SAFE OPERATIONAL PRACTICES
BEFORE OPERATING
WHILE OPERATING
Read Operator’s Manuals
Prior to operating the Turf Tender, read and understand
the contents of this Operator’s Manual and the Operator’s
manual of vehicle either towing or carrying the Turf Tender.
Become familiar with all control functions and know how to
turn the vehicle off and stop effectively.
REPLACEMENT MANUAL
A replacement manual is available by sending complete
Model and Serial Number to
Dakota, Inc.
833 Gateway Drive, North East
East Grand Forks, Minnesota 56721
Unauthorized Operators
Never allow children to operate the Turf Tender. Do not
allow anyone to operate the Turf Tender without proper
instruction or training. Only trained and authorized persons
should operate the Turf Tender.
The operator is defined as being the person responsible
for supervising the operation of the Turf Tender and driving
the vehicle that either tows it or carries it.
Drugs And Alcohol
Never operate the Turf Tender when under the influence
of drugs or alcohol.
Shields And Safety Devices
Keep all shields, guards, and safety devices in place. If a
shield, guard, or safety device is damaged, replace or repair
it prior to operating the Turf Tender. If a decal is illegible,
order and install a new one.
Vehicle Instructions
Mounted-type Turf Tenders are designed to installed on
either the Toro Workman® or the John Deere ProGator®. Refer
to the Operator’s Manual for capacities, instructions, and
precautions.
WARNING
Do not attempt to mount the Turf Tender on a model
other than those listed. Never mount a Turf Tender
on a vehicle that does not have the brakes,
suspension, or frame strength to handle the load.
Trailer-type Turf Tenders can be towed by most utility
tractors with adequate brakes. The tractor pulling 410, 411,
412, and 420 models must have a drawbar hitch capacity to
handle a 7825 lb (3556 Kg) trailer. The tractor pulling 414
and 440 models must have a drawbar hitch capacity to handle
a 13,000 lb (5909 Kg) trailer. Refer to your Tractor Operator’s
Manual for towing capacities, instructions, and precautions.
WARNING
Do not attempt to tow a loaded Turf Tender with a
light utility vehicle or runabout. Never tow a Turf
Tender with a vehicle that does not have the brakes,
suspension, or frame strength to handle the load.
When operating a Turf Tender equipped with electric
brakes on hilly terrain, it is recommended to use the Turf
Tender’s brakes in conjunction with the tow vehicle’s brakes.
The fully loaded weight of the Turf Tender may be beyond
the capacity of the just the tow vehicle’s brakes.
Loose Fasteners And Fittings
Confined Space Operation
Although the Turf Tender has been designed so that
components will not come loose during normal operation of
the Turf Tender, always check the Turf Tender prior to start
up and after each use for loose fasteners, fittings, connectors
and other components. Tighten, repair, or replace as necessary.
This includes electrical and hydraulic system components,
also. Only use original DAKOTA replacement parts.
Danger Zones
Modifications To Turf Tender
Do not modify the Turf Tender in any way. Modifying the
Turf Tender will void the warranty.
Safe Attire
Do not operate the Turf Tender while wearing sandals,
tennis shoes, sneakers, or shorts. Always wear long pants and
substantial shoes. Do not wear loose fitting clothing which
could get caught in control switches or moving parts. The
wearing of safety glasses, safety shoes, hearing protection,
and a hard hat is recommended and may be required by some
ordinances and insurance regulations.
6
Do not run the vehicle’s engine in a confined area without
sufficient ventilation. Exhaust fumes are hazardous and could
possibly be deadly.
The following danger zones exist in and around the Turf
Tender:
1. A crush hazard exists in any area beneath the Turf Tender.
2. A hydraulic jet puncture hazard and hot oil burn hazard
exists in any area within 6 feet (2 m) of a hydraulic hose
due to the possibility of a puncture in a hose.
3. A projectile hazard exists in any area within a 100 foot
(30 m) radius of the rear and sides of the Turf Tender.
Rocks travel farther than sand during normal top dressing
operations.
4. Entanglement, pinch, and cut hazards exist in any areas
close to rotating and moving components such as
conveyors and spinners.
5. A potential entrapment hazard exists within the hopper.
6. On trailer-type Turf Tenders, a crush hazard exists at the
rear and an impact hazard exists at the front of the Turf
Tender during loading or uncoupling if the load is not evenly
distributed and balanced in front of the wheels due to the
rear tipping down. Never load the Turf Tender when it is
uncoupled from its tow vehicle. Never uncouple the Turf
Tender when there is a load in the hopper. There is potential
of the Turf Tender tipping backwards which could cause
damage to the Turf Tender or injury or even death.
SAFE OPERATIONAL PRACTICES
7. A crush hazard exists around the perimeter of the Turf
Tender if operated on a slope exceeding either the
vehicle’s or Turf Tender’s recommended maximum speed
and operational angle (10° side to side and 26° front to
back).
8. On the trailer-type Turf Tenders, a crush hazard exists
due to the Turf Tender rolling if uncoupled from its tow
vehicle. Always solidly chock both the front and rear of
the outermost wheels before uncoupling from the tow
vehicle.
9. On mounted-type Turf Tenders, a crush hazard exists
beneath the hopper when it is raised to do maintenance
on the vehicle. Always install the Safety Bar on the hoist
ram to secure the hopper in the raised position.
10. On mounted-type Turf Tenders, a crush hazard exists
beneath the hopper when removed from the vehicle in
the storage position. Be sure the stands are properly
installed and that no one is allowed beneath the hopper
when in the storage position.
For these reasons, the only person that is allowed to be
near a loaded or operating Turf Tender is the operator seated
in the driver’s position of the vehicle.
You, the operator in control, are responsible for using good,
safe judgment in the operation of the Turf Tender and ensuring
that no one will be injured by it’s operation.
Passengers
Never carry passengers on this Turf Tender. The Turf
Tender is not designed to carry anybody.
Drive Carefully
Using the Turf Tender demands attention to operation.
Failure to operate the Turf Tender safely may result in an
accident, tip over, or serious injury or death. To prevent tipping
or loss of control:
1. Never exceed the tow (or carrier’s) vehicle’s load capacity.
One of the most dangerous operations associated with
the Turf Tender is attempting to haul or tow it with an
undersized vehicle due to the vehicle’s limited traction
and braking capacity. Exceeding the vehicle’s capacity
may result in loss of control, damage, serious injury, or
even death. Refer to your vehicle’s manual for load
capacities and restrictions. Do not use the Toro Workman®
and John Deere ProGator® for the trailer-type Turf Tenders
with hoppers larger than 1 cubic yard (410 & 411 models).
2. Use extreme caution, reduce speed, and maintain a safe
distance when operating around sand traps, ditches,
creeks, trees, ramps, unfamiliar areas, or other hazards.
3. Be alert for severe ground depressions, holes, or other
hidden hazards. If an outside wheel (on trailer-type Turf
Tenders) drops into a hole, it may cause the Turf Tender
to tip over.
4. Use caution when operating the Turf Tender on slopes.
Normally travel straight up or down slopes. Shift the
vehicle into a lower gear before attempting to either go
up or down a slope.
5. Avoid making turns on slopes.
6. Reduce speed when making turns.
7. Use extra caution when operating on wet surfaces, at high
speeds, or with a full load. Stopping time increases with
a full load.
NOTE: A worst-case control scenario exists when
the Turf Tender is being driven down a wet slope at
an angle to the slope and the operator is attempting
to turn and/or brake. Loss of control could result in
an accident, tip over and serious injury or death.
8. Avoid sudden stops and starts. Do not go from forward
to reverse or from reverse to forward without coming to
a complete stop.
9. Do not attempt sharp turns or abrupt maneuvers or other
unsafe driving actions which may cause loss of control.
10. If the vehicle’s engine stalls or loses headway on a hill,
never attempt to turn the vehicle around. Always back
straight down the hill in reverse. Never back down a hill
in neutral or with the clutch depressed using only the
brakes.
11. Make sure the area is clear prior to backing up. Back up
slowly as the visibility behind the Turf Tender hopper is
limited.
12. Always avoid low hanging objects such as tree limbs,
doorways, door jambs, power lines, etc. Ensure there is
enough clearance for both you and the machine(s) you
are operating.
13. Always avoid objects, which may “hook” the wheels such
as trees, posts, etc. Be constantly aware of the width and
turning radius of the Turf Tender. Failure to do so may
result in damage to the vehicle or Turf Tender.
14. Watch out for traffic when near or crossing roads. Always
yield the right of way to pedestrians and other vehicles.
This vehicle was not designed for travel on streets or
highways. Obey all traffic rules and regulations pertaining
to controlled and uncontrolled traffic areas.
15. Limit load size if working on steep or rough terrain.
16. STOP and ask your supervisor if you are ever unsure about
safe operation.
LOADING
WARNING
Never load a trailer-type Turf Tender when it is
uncoupled from its tow vehicle.
When loading material, distribute the load evenly to keep
it from shifting. Operate the Turf Tender with extra care when
the hopper is full of heavy material.
Slowly fill the hopper over a few seconds of time with the
loader bucket as low as possible. Avoid “dropping” the load
into the hopper from an excessively high loader bucket. This
is safer in terms of maintaining a balanced load and will also
extend the life of the Turf Tender.
Make sure the material you are loading has uniform
properties. Material that has few small rocks in it poses a
projectile hazard. Material that has varying composition or
moisture may result in widely varying application rates.
Do not exceed the load capacity of the Turf Tender or
vehicle. Refer to the Specifications section to determine the
maximum load capacity of the Turf Tender.
Never add sideboards to the hopper to increase its capacity
for dense or heavy materials. The additional weight will
increase the chance of tipping or rolling over. The hopper
capacity of the may be increased for low-density materials
such as peat.
SAFE OPERATIONAL PRACTICES

GENERAL INFORMATION
Owners and operating personnel must thoroughly read and
understand this manual in order to properly operate, lubricate,
and maintain the Turf Tender. Failure to do so could result in
personal injury or equipment damage. Refer to this manual
as frequently as necessary.
LABELING AND TERMINOLOGY
The Turf Tender and this manual use the following terms
and symbols to bring attention to the presence of hazards of
various risk levels and important information concerning the
use and maintenance of the Turf Tender.
WARNING: Indicates presence of a hazard which can
cause severe personal injury, death, or substantial property
damage if ignored.
CAUTION: Indicates presence of a hazard which will or
can cause minor personal injury or property damage if ignored.
NOTE: Indicates supplementary information worthy of
particular attention relating to installation, operation, or
maintenance of the Turf Tender but is not related to a
hazardous condition.
Be sure to follow all instructions and related precautions
as they are meant for your safety and protection.
This manual is considered a permanent part of the Turf
Tender and must remain with the Turf Tender when sold.
Use only the correct replacement parts and fasteners. Right
and left-hand sides are determined by facing in the direction
of forward travel.
Record the model and serial numbers in the
specifications section so they are readily available when
contacting a dealer for parts or service. Many owners
employ the dealer’s Service Department for all work other
than routine care, cleaning, and adjustments. We strongly urge
the use of genuine DAKOTA parts to protect the investment
in your Turf Tender.
Our warranty is provided to support customers who operate
and maintain their equipment as described in this manual.
This warranty provides you the assurance that DAKOTA will
back its products where defects appear within the warranty
period. Should the equipment be abused, or modified to
change its performance beyond the original factory
specifications, the warranty will become void and field
improvements will be denied.
AUTHORIZED MAINTENANCE
Perform only the maintenance described in this manual
that you are qualified to perform. If major repairs are ever
needed or assistance is desired, contact an Authorized
DAKOTA Dealer for their professional service.
UNLOAD HOPPER PRIOR TO DOING
MAINTENANCE
Any material in the hopper must be removed prior to
performing maintenance on or beneath the Turf Tender.
POWER OFF MAINTENANCE AND
ADJUSTMENTS
All maintenance and adjustments to the Turf Tender must
be made with the vehicle’s parking brakes set and engine off.
On trailer-type Turf Tenders the vehicle must remain coupled
to the Turf Tender. Failure to do so could result in injury or
even death.
8
TIRES
Check the tires frequently for cracks, checks, and proper
inflation. An under inflated tire poses a significant tipping
and braking hazard and may cause an accident, injury and
death. Do not attempt to jack or perform tire maintenance
with material in the hopper. For trailer-type Turf Tenders, the
recommended tire pressure operating range is 13-18 psi (90124 kPa) for 26.5 in. tires and 15-22 psi (115-169) for 33 in.
tires. Do not exceed the maximum tire pressure listed. Tire
pressure is an indication of the ground pressure the Turf
Tender has on turf; however, using a tire pressure which is
too low may cause tire problems and also result in nonuniform
ground pressure at the tire’s face.
NOTE: For mounted-type Turf Tenders, follow the
tire inflation guidelines found in the vehicle’s
Operator’s Manual or on the sidewall of the tire.
MAINTAIN SAFE OPERATING
CONDITIONS
Grease all fittings as described in this manual. Proper
lubrication is essential for the safe operation and longevity
of the Turf Tender.
Check the conveyor belt(s) for stretch and proper
alignment; adjust accordingly. Each conveyor belt has a Vbelt vulcanized to the back side of the belt to help maintain
proper alignment and carry most of the load; however, it is
still necessary to check and adjust (if necessary) belt
alignment.
Do not allow hydraulic fluid to come in contact with the
belt. The PVC belt material is resistant to fertilizers, but
hydraulic fluid causes the PVC coating on the belt to
decompose. One of the most common causes of hydraulic
fluid on the belt is the placing of uncoupled hose-ends in the
hopper. Under no conditions should this be done.
RELIEVE HYDRAULIC PRESSURE
Before disconnecting or performing any work on the
hydraulic system, all pressure in the system must be relieved
by turning all Turf Tender control switches to their OFF
position, placing the hydraulic supply valve in the float
position, and stopping the engine of the vehicle.
Residual hydraulic pressure may still be present, so care
must be taken. Make sure parts of the Turf Tender actuated
by hydraulic pressure are supported or otherwise restrained
to prevent movement prior to relieving hydraulic pressure.
Failure to do so could result in damage, injury or even death.
KEEP TURF TENDER CLEAN
Keep the Turf Tender free of excessive grass, leaves, and
accumulations of dirt and sand. Materials such as this can
compromise seals and bearings.
REPLACEMENT PARTS
To ensure optimum performance and safety, always
purchase genuine DAKOTA replacement parts and
accessories. NEVER USE “WILL-FIT” REPLACEMENT
PARTS AND ACCESSORIES MADE BY OTHER
MANUFACTURERS. Using unapproved replacement parts
and accessories voids the warranty of the DAKOTA Turf
Tender.

SETUP
TRAILER-TYPE TURF TENDERS
To properly setup the Turf Tender, several items will need
to be performed in conjunction with the tow vehicle. You
will need to install the power cord and control box mount on
the tow vehicle. The power cord supplies electrical power to
the control box from the tow vehicle. This power cord should
be left in place after the initial installation.
CAUTION
Always complete a safety inspection before hooking
to the tractor and before using the Turf Tender. This
safety inspection “walk around” is described in the
safety section of this manual.
Main Power Cable
1. Route the power cord from the battery, beneath the tractor
platform, and over to the right rear fender of the tractor.
Make sure the cord does not contact any hot or moving
parts and will not be pinched under the fender. Leave
some slack in the cord at the control box end so that the
cord will not pull loose if the control box shifts or moves.
2. Using cable ties, attach the cord to the tractor in several
places. Make sure the cord will not come loose and move
into a position to become pinched or cut.
3. Attach the red wire eyelet to the positive terminal and
the black wire eyelet to the negative terminal on the tractor
battery.
NOTE: If it is desired to mount the control box to
the roll bar of the tractor, a bracket must be designed
and built.
CAUTION
Do not drill holes in the roll bar to mount the control
box bracket to the roll bar. Holes in the roll bar may
weaken the structure.
Hold the bracket in the desired mounting location
making sure there are no electrical wires in the area (above
and below the fender). Using the bracket as a template,
mark the location for the four mounting holes on the fender;
then center punch the holes. Remember to allow room for
removal and installation of the control box from the bracket
without interference since the control box stays with the
Turf Tender when unhooked from the tractor.
Using a 1/4 in. drill bit, drill the holes in the fender. Using
the hardware included, secure the bracket to the fender; tighten
securely. Remove the 7/16 in. nut securing the control box to
the Turf Tender. It is for shipping purposes only and is not
needed for regular use or storage.
CAUTION
Before using Turf Tender for the first time, check
the wheel bolts to make sure they are tight. They
must be torqued to 90 ft-lb (12.4 kg-m).
Mounting The Control Box
WARNING
Recheck each wheel bolt’s torque within the first 1
hour of use and every 10 hours thereafter until the
bolts maintain the proper torque. Failure to do so
may result in a serious accident.
CAUTION
It is the operator’s responsibility to inspect and
torque the lug bolts upon delivery and during normal
usage.
The mounting bracket for the control box is to be mounted
in a position convenient for the operator (either on the right
rear fender, on the dash, or to the roll bar of the tractor). Select
a location for mounting the bracket making sure you will be
able to remove and install the control box from the bracket
without interference. To mount the bracket to the fender, use
the following procedure:
10
WARNING
Check the tire pressure on all tires and look for any
obvious leaks in the hydraulic system prior to each
use. Failure to do so may result in a serious accident.

2. While wearing gloves and safety glasses, hold the longest
free side of each band; then carefully cut each of the bands
(as close as possible to a corner) securing the hopper to
the skid.
CAUTION
The bands are under tension. Wear gloves and safety
glasses. Cut as close as possible to a corner while
holding the longest free side of each band.
3. Insert the Dakota Lift Bar (p/n 11361) beneath the sides
and rear lip of the hopper.
NOTE: Prior to mounting the Turf Tender 410T on
the Toro Workman, it is required to install the proper
Auxiliary Hydraulic Kit. Order the proper kit
(gasoline or diesel engine) for your machine; then
using the installation instructions included with
each kit, install the kit.
Removing Components From Skid
1. To avoid damage, transport the hopper/skid carefully.
4. Lift the hopper straight up until clear of the pedestal on
the skid. Hold securely until ready to place on either the
vehicle or hopper legs.
WARNING

SELF-CONTAINED TURF TENDERS
Self-contained Turf Tenders have their own power supply
and hydraulic system. The power supply used is a Honda 11
hp engine. The engine provides power to the hydraulic pump
which draws hydraulic fluid from the reservoir and circulates
the fluid to the drive motors on the Turf Tender.
In addition to following the setup information for trailertype Turf Tenders, the following information must also
adhered to.
Before Operating For The First Time
1. Check the level of the hydraulic fluid. A sight gauge is
built into the front side of the reservoir. Fill as required.
2. Check the oil and gasoline levels in the engine. Fill as
required.
NOTE: The engine has oil fill/check caps and drain
plugs on both sides. The gray plug is the dipstick
and is located on the front side of the engine.
3. Read and understand all information in the Honda engine
Operator’s Manual.
Note: This engine has no Transmission/centrifugal
clutch; therefore, ignore pages 29-30 in the Honda
engine Operator’s Manual.
2. Check engine oil and gasoline levels.
3. Check the position of the choke, fuel valve, throttle and
key switch. See the engine manual for proper use of each.
4. Ensure master switch on control box is in the OFF
position. Be sure all persons are clear of conveyor and
spinner areas; then using the key switch on the control
box, start the engine.
Before Starting Engine
1. Using the sight gauge, check the oil level in the hydraulic
reservoir.

SETUP
OPERATION
SAFETY INSPECTION
Introduction
Every day before operating the Turf Tender, it is important
to perform a safety inspection “walk around” of the Turf
Tender. The purpose of the safety inspection is to inspect the
Turf Tender for any unsafe conditions and maintenance
concerns. Finding these conditions before using the Turf
Tender can save time, money, and the possibility of injuries.
Check for loose nuts or bolts, broken or cracked metal and
welds, bent or damaged components, under-inflated tires and
leaking hydraulic components and hoses. Any of these
conditions may indicate a potentially serious situation. All
Turf Tender models require the same basic safety inspection
procedure.
On trailer-type models, start the inspection at the hitch.
Check the hitch for excessive wear or cracks. Check the
tongues of the hitch coupler (the part that directly hitches to
the tractor drawbar). The coupler is made of cast iron and
designed to break away in case the Turf Tender is driven on
an unsafe slope and rolls. The cast iron tends to wear faster
than steel and does wear out. This coupler may be turned
over to allow wear on both tongues before replacement is
necessary. Make sure the bolts attaching the hitch are not
loose. On models with a front door, check to make sure the
track is not full of material and that it has not been damaged.
At the back of the Turf Tender, continue to look for
hydraulic leaks and other unsafe conditions. Check the
conveyor belt for damage and proper alignment. Make sure
the shield over the twin spinners is not bent or interfering
with the operation of the spinners. Make sure the rear door
and gate are not bent or damaged and are closed as much as
needed for the materials you will be hauling. By hand, rotate
each spinner to ensure that it is not bent and clears other parts
of the spinner/chute assembly.
On the right side of the Turf Tender, visually, make sure
the tire(s) are inflated properly. On models with a side
conveyor, check the side conveyor for damage and proper
alignment. Check for any signs of hydraulic leaks.
Check the left side of the Turf Tender for any unsafe
conditions. Much of the hydraulic system is based on this
side. Check for any hydraulic leaks. Visually, make sure the
tire(s) are inflated properly. If in doubt, use a tire gauge and
check the tire pressure. Check for loose wires. All wiring
should be secured to the Turf Tender and should not be
hanging loose.
When finished with the safety inspection and any repairs
or adjustments that need to be made, the Turf Tender is ready
for operation.
OPERATION
15
HOOKING TO THE TRACTOR (TRAILER
MODELS)
It is required that the tractor be equipped with a regular
drawbar. Set the drawbar length to the longest position for
maximum turning clearance between the tractor and the Turf
Tender. Do not use either a 3-point drawbar or any type of
clevis hitch.
NOTE: The jack stand can also be removed
completely and stored in the toolbox if that is desired.
The jack stand should always be kept near the Turf
Tender if it becomes necessary to unhook quickly.
CAUTION
Do not use a 3-point drawbar since it limits
maneuverability. It may also damage the hitch on
the Turf Tender.
Back the tractor up to the Turf Tender so that the tractor
drawbar lines up with the hitch on the Turf Tender. Set the
parking brake and shut off the tractor. Using the Turf Tender
jack stand, level the Turf Tender; then compare the height of
the tractor drawbar with the height of the hitch. If necessary,
adjust the height of the hitch coupler so that the Turf Tender,
when pulled, will be level. To adjust hitch coupler height,
remove the bolts and nuts securing the coupler, move the
coupler either up or down as necessary, and secure with the
bolts and nuts. Tighten securely. Using the jack stand on the
Turf Tender, raise or lower the hitch as needed to align the
tractor drawbar and hitch. Start the tractor, release the parking
brake, and back into position.
NOTE: Adjustment of the hitch coupler height will
only have to be made the first time the Turf Tender
is to be hooked up to the tractor.
Set the parking brake and shut off the engine. Secure the
Turf Tender to the drawbar using a 5/8 inch pin. Secure the
pin with either a hitch pin or cotter key.
Noting the supply and return hydraulic couplings for both
the tractor and Turf Tender and making sure the couplings
are clean, hook up the two hydraulic hoses to the tractor
couplings. The hoses must be attached to the proper couplings
for the Turf Tender to operate properly.
NOTE: The hose that goes to the supply coupling
on the tractor is marked at the factory with a plastic
cable tie. The tractor supply coupling will vary from
tractor to tractor.
CAUTION
Make sure that the hose ends and tractor couplings
are clean before hooking up hydraulic hoses.
Contamination of the hydraulic system may cause
failure of components on the Turf Tender and tractor.
CAUTION
Do not use bolts or other substitutes for a hitch pin.
These may not be strong enough and may cause
the Turf Tender to disconnect.
Using the jack stand, lower the hitch of the Turf Tender
until all Turf Tender weight is on the drawbar of the tractor
and the jack stand is loose. Remove the pin securing the jack
stand, turn the jack stand 90 degrees counterclockwise (putting
the bottom of the jack stand toward the rear of the Turf Tender)
and install the pin. This is the stow position for the jack stand
and will keep it out of the way during all operations.
16
OPERATION
Excess hose and wiring harness length should be coiled
and secured to the top of the Turf Tender’s hitch frame. If the
same tractor is used with the Turf Tender every time, the
excess hose and harness length coil my be left secured to the
hitch. Leave some slack in both the hoses and the wiring
harness for turning and maneuvering the Turf Tender.
CAUTION
Do not allow the hoses or wiring harness to wrap
around any parts of the tractor or to drag on the
ground.
Remove the control box from the front of the Turf Tender.
Start the tractor engine; then engage the tractor hydraulic
system. Test all functions of the Turf Tender. If the hydraulic
functions of the Turf Tender are not operating properly, more
than likely the hoses are hooked up backwards. If everything
works properly, the Turf Tender is ready for operation.
NOTE: If necessary to switch the hose connections,
set the parking brake, if you have released it, and
shut off the tractor engine. Relieve the pressure on
the hydraulic system by moving the tractor hydraulic
valve to the neutral position; then switch the
hydraulic hose connections. Start the tractor engine
and test the hydraulic functions of the Turf Tender.
UNHOOKING FROM THE TRACTOR
(TRAILER MODELS)
Slide the control box into the mounting bracket on the
tractor. Secure by tightening the screws on the back of the
bracket.
WARNING
The Turf Tender must not have any material in the
hopper when uncoupling. Failure to empty the
hopper prior to unhooking from the tractor may
result in a rear tipping hazard resulting in damage,
injury or even death.
Find a level, dry place to park the Turf Tender. Set the
parking brake on the tractor and shut off the engine.
WARNING
Park the Turf Tender on a flat, solid surface. Parking
the Turf Tender on an incline may create an unsafe
condition. It may be necessary to chock the Turf
Tender wheels to remove the possibility of it rolling
from its parked position.
Inspect the 2-wire power cord connector to make sure it is
clean and not worn or damaged. Good electrical connections
are important so all functions, especially if equipped with
electric brakes, are working properly.
Connect the 2-wire power cord to the control box.
CAUTION
Do not allow the hoses or wiring harness to wrap
around or fasten to any part of the tractor other than
the connectors at the tractor. The hoses and wiring
harness are designed to pull loose if the Turf Tender
disconnects.
Relieve the pressure on the hydraulic system by moving
the tractor hydraulic valve to the neutral position.
Unplug the control box from the 2-wire power cord. Loosen
the screws on the back of the bracket; then remove the control
box from the mounting bracket. Place the control box in the
storage position on the front of the Turf Tender. Make sure
the wiring harness is not wrapped around any part of the tractor
during the transfer of the control box to its storage position.
Disconnect the hydraulic hoses. Coil and cap them and
place them on the top of the hitch frame for storage. Do not
allow the hoses to fall in the dirt. Also, do not set the hoses in
the hopper or on the conveyor belting.
CAUTION
Do not allow hydraulic oil from the hoses to come
into contact with the conveyor belt. The belt is made
of a PVC compound to resist damage by fertilizers
but it can be damaged by hydraulic oil.
OPERATION
17
Remove the pin securing the jack stand in the stow position;
then turn the jack stand upright and install the pin. Using the
jack stand, lift the hitch of the Turf Tender until it is no longer
putting weight on the tractor drawbar.
Chock the Turf Tender wheels to prevent movement; then
remove the pin from the hitch.
Make sure there is no further connection between the
tractor and the Turf Tender. Get on the tractor, start the engine,
release the parking brake and drive away.
WARNING
The Turf Tender must be hooked up to the tractor
prior to loading. Failure to do so may result in
damage, injury or even death.
HOPPER CONVEYOR BELT SYSTEM
Overview
The conveyor running along the bottom of the hopper on
the Turf Tender is used to unload the hopper. It is generally
run backward to unload material from the back of the hopper.
On models with a front door, the conveyor may be reversed
to run material out the front. The conveyor controls are located
on the control box, which should be mounted on the towing
vehicle.
Two types of belts are used (depending upon model) for
the hopper conveyor. Spliced and endless belts are the two
types of belts used. Each conveyor belt has a center V-belt
vulcanized on the inner side to help keep the belt centered on
the rollers. Instructions for tightening of the belt and belt
replacement follows later in the Maintenance section.
On larger models (414, 420, and 440), the conveyor has
drive motors on each end. The dual drive motor design gives
additional power in each direction and also helps limit the
chances of belt slipping off track.
On the 420 and 440 models, a diamond wiper system is
located between the belts in the center of the hopper. This
wiper is used to help eliminate a buildup of materials on the
inner side of the belt. A material buildup could cause the belt
to run off track or jam. The diamond wiper generally prevents
these problems.
Turf Tender models are equipped with either an electric
or manual control to adjust the speed of the conveyor belt.
On all models (except the self-contained models, the master
switch must be turned on first to allow the other controls
to function. The red light on the control box will be
illuminated when the master switch has energized the rest of
the control box functions.
18
NOTE: To prevent battery discharge, remember to
turn the master switch and the towing vehicle’s
ignition switch to the OFF position when not using
the Turf Tender.
On models with only a rear gate, the conveyor switch is a
two position switch (ON and OFF). On models with front and
rear gates, the conveyor switch is a three position switch
(REARWARD-OFF-FORWARD). Moving the switch from the
OFF position, will engage the belt in the direction as indicated
on the switch decal. To unload the hopper, be sure to open the
appropriate gate before running the conveyor. The gate(s) may
be left open a limited amount if the material being hauled does
not leak out when the conveyor is not running.
NOTE: Before starting the main conveyor belt when
unloading from the rear, always first activate the
spinners. Failure to due so will result in material
piling up on the spinners.
The speed of the spinners may be adjusted to control the
spread width of the Turf Tender. There are two methods to
adjust hydraulic flow to the Turf Tender. Increasing the speed
of the conveyor increases the amount of material being
unloading. Use the appropriate section below to adjust
conveyor belt speed.
NOTE: Conveyor belt speed may also be adjusted
by changing the throttle speed on the vehicle (or
engine) supplying the hydraulic power. Speeding up
the engine will speed up hydraulic flow to the
machine. This will speed up the operation of all
features of the Turf Tender.
ELECTRIC-CONTROL MODELS
The master switch on the control box activates the
hydraulic valve. Once the master switch is in the ON position,
the switch marked “conveyor” will turn the conveyor ON
and OFF. The conveyor speed dial controls the belt speed
(flow rate) of material. Faster belt speeds result in higher
application rates. The numbers on the dial’s scale do not
represent any particular units, they are simply reference
numbers to allow you to set the speed the same each time.
The relationship between flow rate and dial scale are fairly
linear; therefore, if the dial was initially set at 40, raising the
setting to 80 would roughly double the material application
rate.
OPERATION
MANUAL-CONTROL MODELS
Hydraulic flow to the Turf Tender is controlled by the
hydraulic controls of the tow vehicle. As soon as the tow
vehicle’s hydraulic system is activated, the spinners will spin.
Once the hydraulic system is ON, the switch on the control
box marked “conveyor” controls the ON/OFF function of the
hydraulic valve. On the manual-control system, conveyor
speed adjustments are made on the valve located on the side
of the Turf Tender. The speed of the conveyor is not to be
adjusted while the Turf Tender is running. The scale on the
speed control valve is not calibrated to represent any particular
units, however much like the electric-control model, the scale
is fairly linear. Upon completing an adjustment on models
using a diverter valve, secure the adjustment by tightening
the thumb screw securely.
SIDE CONVEYOR
Overview
The side unloading conveyor is a unique option of the Turf
Tender line of material handling systems. It allows the vehicle
operator, while seated on the tractor, to control the unloading
of materials with a complete view of the operation. The side
conveyor may be used to fill other smaller Turf Tenders, sand
bunkers, trenches or almost anything else you may want to
unload material into. Keep the small top dressers busy by
filling them out on the job site rather than pulling them back
to the supply pile.
NOTE: On manual-control models, the control box
switch marked “spinners” is a dummy switch. The
spinners are only turned ON and OFF by activating
or deactivating the tow vehicle’s hydraulic system.
There are two positions for the side conveyor. The
traveling position is when the side conveyor is retracted and
rests against the side of the hopper. The operating position
is when the side conveyor is fully extended to the side.
CAUTION
Do not adjust conveyor or spinner speeds on
manual-control models while operating the Turf
Tender. The operator should always remain seated
on the vehicle when the engine is running and no
other people should be near the Turf Tender while
the engine is running. To safely adjust the hydraulic
flow on all models except the electric-control
models, Dakota recommends that:
1. Operator sets parking brake.
2. Operator shuts off the engine.
3. Operator dismounts and adjusts flow.
4. Operator returns to vehicle and starts engine.
5. Operator tests Turf Tender using new setting.
6. Operator repeats process as often as necessary
to obtain correct flow and conveyor speed.
The normal operating procedure is to preset the conveyor
speed; then as you pass onto the area you want to spread
material, turn the conveyor switch to the ON position. As
you travel off the area, turn the switch to the OFF position.
Generally it is recommended to run the conveyor at a fairly
high speed and adjust the rear metering gate to control the
application rate. Conveyor speed affects the placement of
material on the spinners. Slow conveyor speeds result in the
“holding” of material on the spinners longer resulting in more
wrap around. With some materials, having too fast of a conveyor
speed may result in a very narrow spread pattern (where all the
material is discharged directly behind the Turf Tender).
Traveling Position
Operating Position
The conveyor must be fully extended to the operating
position to be used. If it is not fully extended, the material
from the main conveyor will spill before being unloaded onto
the side conveyor; thereby, dumping most, if not all, of the
material in front of the Turf Tender rather than unloading
onto the side conveyor.
Three switches control the functions of the side conveyor.
The side conveyor IN/OUT switch swings the conveyor in
and out. The UP/DOWN switch raises and lowers the side
conveyor. A third switch on the control box activates either
the side conveyor or the spinners. Pushing the switch one
way activates the side conveyor; pushing the switch the other
way activates the spinners. All three switches have a center
position which is the OFF position.
Lifting the side conveyor to its highest position and lifting
the hood makes it more effective for filling bunkers or holes
as the material can be thrown further. Varying the throttle
speed of the tractor while unloading allows the material to be
spread over a wider area.
The electric hood position is controlled by one switch.
Push the switch away from the tractor operator and hold to
lift the hood. Pull the switch toward the operator and hold to
lower the hood. Releasing the switch at any point will stop
the hood at whatever position it is in.
OPERATION
19
Lowering the side conveyor to its lowest position makes
it easier and more accurate for filling trenches, pots, or areas
that require some degree of unloading accuracy. With the hood
at the end of the conveyor in the down position it forms a
spout that helps keep the unloading materials in more of a
controlled space and results in less time spent cleaning up.
Operation
To unload the hopper using the side conveyor, use the
following procedure:
1. Open the front gate to the desired height.
NOTE: On models equipped with electrically
activated front gate, use the switch on the control
box to open the gate to the desired height.
2. Using the IN/OUT switch, move the side conveyor to the
operating (fully extended) position.
3. Using the UP/DOWN switch, adjust the side conveyor
to the desired height.
NOTE: If desired to throw the material further, use
the HOOD switch to raise the side conveyor hood.
4. Activate the side conveyor; then start the hopper conveyor.
NOTE: Always activate the side conveyor before
starting the main conveyor. This prevents the
buildup of material on the side conveyor and limits
excessive wear and belt-related problems.
5. If moving while unloading the hopper using the side
conveyor, be sure to stay away from trees, poles and other
obstacles which may come in contact with the side conveyor.
Also, do not drive too closely to bunkers and other dropoffs.
WARNING
Do not drive too close to edges of bunkers or other
dropoffs. The Turf Tender may roll over if the edge
collapses under the outside wheel or if it is
maneuvered incorrectly. This could result in injury
or death.
6. Shut off the hopper conveyor; then turn the side conveyor
off so material does not build up on the side conveyor.
7. Using the UP/DOWN switch, lower the side conveyor to
the fully down position; then using the IN/OUT switch,
move the side conveyor to the traveling position.
8. Close the front gate.
HYDRAULIC REAR DOOR (Optional)
The hydraulic rear door is designed to allow the operator
to unload material quickly without leaving the seat of the
tractor.
A switch on the control box operates the hydraulic rear
door. Pushing the switch away from the operator opens the
door; pulling the switch toward the operator closes the door.
An indicator rod gives the operator an indication of how far
the door is open.
CAUTION
Never close the hydraulic rear door when the hopper
is full of material. Trying to close the door when the
hopper is full could result in damage to the door or
to the rear of the hopper. The door should always
be closed prior to filling the hopper.
The rear door is a structural component of the hopper
assembly, and as such, it must be kept tightly closed when
the hopper contains material and the Turf Tender is being
towed over rough terrain. Failure to keep the door closed
in these conditions may result in cracking of the hopper
assembly.
NOTE: It is not uncommon for the hydraulic system
to “bleed down” or lose pressure when not in use.
Avoid leaving the hopper full of material when not
in use since the material may push the rear door
open as the hydraulic pressure bleeds down.
CAUTION
The side conveyor must be in the fully down position
prior to swinging it in to the travel position next to
the hopper. Failure to do so will result in damage to
the Turf Tender.
20
OPERATION
REAR METERING GATE
As you test the metering gate for material flow, you should
also check for material leakage under the side wipers of the
hopper.
Manual Rear Metering Gate
The rear metering gate is designed to regulate the flow of
material out of the hopper. Two types of the metering gate
are available: hand crank, or manual opening.
NOTE: Stainless steel inserts may be purchased and
installed to limit the width of the gate opening on
412, 414, 420, and 440 models. Narrowing the gate
opening gives a little better control over spread
distribution with difficult material such as wet, sticky
sand.
The rear metering gate may be left open a limited amount
if the material you are hauling across your facility does not
flow (leak) out when the conveyor is not running. Dry sand
and fertilizers are especially bad for leaking out and we
recommend the metering gate be fully closed when
transporting these materials.
There is a scale beside the gate to show you how far the
gate is open (general reference only). The gate opening height
for each operation will need to be determined. For example,
a light topdressing may require the gate to be open 1/8 in. (3
mm); whereas, for a heavy topdressing and core filling, the
gate may have to be open 4-5 inches (10-12 cm). The operating
speed also affects the amount of material you are dispensing.
If accurate calibration of material delivery rates is required,
the actual gate opening should be determined using the
following steps:
1. Make sure the conveyor belt is properly tensioned. Refer
to belt adjustment in the Maintenance section.
2. Press down firmly on the gate so it depresses the belt as
far as it will go; then lock in place with the hand screws.
It requires about 40 to 50 pounds of force to set the
metering gate in the fully closed position. This must be
done since the belt drops slightly below the gate opening
when material is in the hopper. Make sure the gate appears
level.
3. Using a ball point pen, draw a line on the back wall of
the hopper across the top of the metering gate. This is
your “zero” gate opening reference line.
4. On both the right and left ends of the reference line, draw
a scale (fractional inches or millimeters) going up from
the line for an exact gate opening reference.
NOTE: When the metering gate is set to its “zero”
position, material will still flow out the Turf Tender
conveyor when the conveyor is in operation. The
belt cups will actually allow about an 1/8 inch layer
of material to come out the metering gate.
The metering gate is secured by the two turn-screws, one
on each side. To adjust gate height, loosen the two turn-screws,
adjust to the proper height (either by hand or by using the
hand crank), and tighten the turn-screws to secure the
adjustment.
Depending upon the material being applied, the gate may
be left open 1-3 inches (2.5-7.5 cm) even when transporting
materials. Sand and other large aggregate type materials will
not flow out at these openings under normal conditions. Finer
materials such as grass seed may tend to flow out even when
the gate is open a small amount.
FRONT GATE
The electric front gate function adds both safety and
convenience to the operation of the machine. The tractor
operator can open and close the gate from the seat of the
tractor so no one needs to get close to the machine when it is
working. That also means that only one operator is required.
The electric front gate is easy to operate. One switch moves
the gate either up or down. Push the switch away from the
tractor operator and hold to open the gate. Pull the switch
toward the operator and hold to close the gate. Releasing the
switch will stop the gate at whatever position it is in.
The purpose of the front gate is control material flow out
the front of the Turf Tender. Material may be unloaded directly
in front of the machine or to the side using the side conveyor
in the operating position.
Depending on the material being hauled, the front gate
may be left open a small amount. Because of the relative
position of the gate opening to the end of the main conveyor,
many materials will not leak out if the gate is left open 1-2
inches. If you plan to leave the gate open, monitor it while
you are filling the hopper to see if you will have a problem.
Always close the gate to the position you need before filling
hopper. Trying to force the gate closed when the hopper is
full may damage the gate or the front of the hopper.
Keep the gate clean and keep the track free of debris. This
limits excessive wear and potential damage from the gate
jamming on the debris.
OPERATION
21
ELECTRIC VIBRATOR
An electric vibrator is an option available for all Turf
Tender models. The vibrator is designed to help break up
material bridging problems in the hopper. As the main
conveyor belt pulls material out of the bottom of the hopper,
some material (i.e. wet sticky sand) can bridge or form a
hollow tunnel through the bottom of the hopper. The vibrations
from the electric vibrator will normally shake the material
loose so that it will drop onto the conveyor belt.
For all models (except the self-contained models), the
master switch must be turned to the ON position to allow all
other controls to function. The red light will be illuminated
when the master switch has energized the rest of the control
box functions.
NOTE: To prevent battery discharge, remember to
turn the master switch to the OFF position when
not using the Turf Tender.
Activate the vibrator using the vibrator switch on the
control box. Sometimes 2 or 3 short bursts are needed to break
the material loose. The switch is a momentary switch and
should never be held in the ON position for extended periods
of time.
CAUTION
Do not operate the vibrator continually as excessive
wear on the motor will result. Excessive compaction
of material in the hopper can also result making it
much more difficult to unload.
DUAL SPINNER SYSTEM
The dual spinner function of all Turf Tenders is the same.
A variety of materials from sand and larger aggregates down
to grass seed and fertilizer may be spread. Coverage widths
may be as wide as 50 feet (15 m). It should be noted that
“fine tuning” the system for the specific material being spread
is essential.
CAUTION
Always turn the spinners on before starting the main
conveyor. Failure to due so will result in material
piling up on the spinners.
Material discharged from the spinners can be very
dangerous; therefore no other people should be near the Turf
Tender when spreading and the operator should remain in the
tractor’s seat while the tractor is running. The velocity of
discharged material can exceed 60 miles per hour.
Electric-Control Models
The switch on the control box marked “spinner” controls
the On/Off function of the hydraulic valve. The spinner speed
dial controls the speed of the spinners. The numbers on the
dial’s scale do not represent any particular units, they are
simply reference numbers to allow you to set the sinner speed
the same each time. The relationship between spinner speed
and dial scale are fairly linear; therefore, if the dial was
initially set at 40, raising the setting to 80 would roughly
double spinner speed.
Operation
The dual spinner system is very easy to operate. The
“spinner” switch on the control box activates the spinners.
Most operators leave the spinners on at all times while
spreading a load and only turn the spinners off when the
hopper is empty. The conveyor should be turned ON as you
start a pass and OFF as you complete the pass and turn around.
22
OPERATION
Manual-Control Models
On the manual-control system, spinner speed adjustments
are made on the valve located on the right side of the Turf
Tender. The speed of the spinners is not to be adjusted while
the Turf Tender is running. The scale on the speed control
valve is not calibrated to represent any particular units,
however much like the electric-control model, the scale is
fairly linear. Upon completing an adjustment on models using
a diverter valve, secure the adjustment by tightening the thumb
screw securely. To adjust the spinner speed on your manualcontrol system, use the following procedure:
1. Operator sets parking brake.
2. Operator shuts off engine.
3. Operator dismounts and adjusts flow.
4. Operator returns to tractor and starts engine.
5. Operator tests Turf Tender using new setting.
6. Operator repeats process as often as necessary to get correct
flow and correct speed.
CAUTION
Use care and firmly support the spinner when
removing and installing. Also, be sure the spinner
is firmly locked on the shaft.
Adjustments
OVERVIEW
A variety of materials from sand and larger aggregates
down to grass seed and fertilizer can be spread with Turf
Tenders. All Turf Tenders use the same spinner disk
assemblies. The 410 Turf Tender models use smaller hydraulic
motors and is designed for light and heavy topdressing,
seeding, and fertilizer applications. All other Turf Tender
models are designed for light to heavy application rates and
use larger hydraulic motors. Coverage can be as wide as 50
feet (15 m). It should be noted that “fine tuning” the system
for the specific material being spread is essential. The

application rates and types of material may warrant changing
the blades from their “neutral” position. Also, gate opening,
spinner speed, and conveyor speed will affect the pattern. In
general for best application of material, avoid running the
conveyor too slowly and avoid running the spinners too
fast. The factory “neutral” setting was designed to yield the
best spread pattern under the following conditions:
Material: moist sand (barely clumps when hand squeezed)
Gate Opening: 3/4 in. (from the flat of the belt)
Conveyor Speed: 70 RPM (about 70% dial setting)
Spinner Speed: 350 RPM (about 65% dial setting)
OPERATION
23
The following illustration represents how three blades may
be set to hold the material a little longer and three other blades
are set to release material a little sooner. An overview on
pattern distributions and blade settings follows.
NOTE: Do not be too concerned about achieving
the maximum spread width; instead, focus on
getting a good distribution of your spread pattern.
The “neutral” blade setting, points the blades at the center
of the spinner shaft. There is a diamond cut in the spinner
disk indicating the “neutral” position bolt hole for each blade.
SPREAD PATTERNS AND
ADJUSTMENTS
Overview
WARNING
All spinner blade fasteners must be tightened after
each adjustment. Failure to do so could result in
injury or even death.
WARNING
The setting the spinner and conveyor speeds on
some models, requires the use of a hand-held
tachometer. Remove the spinners prior to measuring
the spinner rpm. Failure to do so could result is
serious injury or even death.
NOTE: Conveyor speed indicators are either located
on the control box or on the left side of the Turf
Tender.
24
Spread pattern is defined as the uniformity of material
distribution. Calibration refers to controlling the amount of
material deposited over a set area.
Prior to setting up the Turf Tender for calibration, the
following items must be correct:
A. The conveyor belt rear roller must be positioned 5 1/4 in.
(13.3 cm) from back wall of vertical chute.
NOTE: This is measured from the flat portion of the
belt.
B. The conveyor belt must be properly aligned and tensioned.
If adjustment is necessary, make the necessary
adjustments at the front end of Turf Tender.
C. On trailer-type models, all tires must be properly inflated.
Adjust tire inflation pressure so all tires are equal and
suitably low to avoid excessive soil compaction. The
recommended tire pressure operating range is 13-18 psi
(90-124 kPa) for 26.5 in. tires and 15-22 psi (115-169)
for 33 in. tires. Remember, the inflation pressure of the
tire indicates how much compaction you are imparting
on your soil. Running the tire pressure too low may
however cause damage to the tire.
D. The spinner shafts must be vertical. If necessary, on trailertype models, make the initial adjustment by changing the
hitch height. If unable to bring the spinner shafts fully
vertical by changing the hitch height, it may be necessary
to adjust the spinner assembly until the spinner shafts are
vertical.
OPERATION
E. The hopper wipers must be adjusted tightly down onto
the conveyor belt. Failure to properly adjust the hopper
wipers results in an adverse spread pattern and application
rate. Adjust the hopper wipers by pushing the belt fully
downward; then adjust the wipers tightly down to the
belt and secure the adjustment.
F. Set the metering gate opening to the approximate material
flow rate. Do not open the gate too far. Instead travel
slower over the area to get a higher application rate.
Opening the gate too high affects the controllability of
the pattern. For most materials, 3-4 inches (7.6-10 cm)
seems to be the point at which pattern controllability
problems arise. Available hydraulic power from the tractor
may also be a limiting factor in your gate setting.
G. Calibrate spinner speed to 325-350 RPM. Extensive
testing has shown that excessive spinner speed results in
uncontrollable patterns, material hitting the spinner shield
and heavy material deposits in the center. Furthermore,
increasing the spinner speed to 500 RPM, increases your
spread pattern width by only 10-15 feet (3-5 m) and results
in segregation of particulates such that fine ones only go
a few feet and the larger ones travel to the outer region of
the pattern. This causes detrimental results with precision
topdressing and fertilizer application.
Basic Spinner Adjustments
If the spread pattern is heavy in the middle, adjust three of
the six blades (every other one) on each spinner disk two
notches in the hold direction; then test the spread pattern. If
necessary, move the same blades two more notches in the
hold position. If additional adjustments are desired, move the
remaining three blades (that haven’t been adjusted) two
notches in the hold direction.
If the spread pattern is heavy on the outside, adjust three
of the six blades (every other one) on each spinner disk two
notches in the release direction; then test the spread pattern.
If necessary, move the same blades two more notches in the
release position. If additional adjustments are desired, move
the remaining three blades (that haven’t been adjusted) two
notches in the release direction.
The following photo illustrates the hold and release angles
for a right spinner disk which rotates counterclockwise.
Collection Methods
H. Calibrate conveyor speed to approximately 70 RPM. This
will result in material just “skimming” the back wall of
the vertical spinner chute. The placement location of
material on the spinners has proven to be a critical variable
in the adjustment and control of the spread pattern.
I. Take note of the material type, condition, and supplier.
Material, which has varying moisture and/or clay content
from one week to the next, may behave differently each
time you spread it. Wet sand, with high clay content, is
among the hardest materials to spread. For these reasons,
try to maintain uniform material conditions. Sometimes
it’s as simple as talking with your supplier to arrange for
uniform material to be supplied and covering the material
pile with a tarp so it is not exposed to the elements. In
direct contrast, dry graded silica sand (hour glass sand)
is probably the easiest material to spread.
The establishment of these preliminary setup steps was
developed through extensive testing and experience. For
example, the conveyor belt’s rear roller distance of 5 1/4 in.
(13.3 cm) from the back wall of the vertical spinner chute was
found to give the best control of spread pattern distribution
with all of the various spinner blades. This applies to all models.
STANDARD PAN COLLECTION METHOD
The typical method of testing the spread pattern is to place
collection pans in a row going across the direction of travel.
Make one or more passes across the pans and measure the
amount of material in each. This doesn’t work with large
broadcast spreaders.
The amount of material collected in each pan can be
graphed to reveal the type of spread pattern you are producing.
A perfect rectangular pattern is very hard to achieve and, in
some cases such as fertilizer application, not desirable because
you would have to drive impossibly precise to avoid skips or
double application. The inherent limitation of this testing
method is that particles coming out of a broadcast spreader
have a very low trajectory angle with high velocity and usually
skip across the surface. Most test runs will have sand sliding
across the pan and launching out the opposite side. We have
even tried using square “egg crate” inserts of varying sizes to
provide better capture of material but we still had material
skipping across the top. Therefore, the industry-standard pan
collection method does not accurately reflect the true
distribution of material.
OPERATION
25
STATIONARY TESTING METHOD
Although there are no references to doing this in industry,
we have found that it is best to run several stationary tests of
the system to quickly find the operational settings of the
spinner blades. By spreading material in an empty parking
lot or another area having a paved surface, you will be able to
quickly clean up the discharged material for reuse as well as
be able to observe the uniformity of the spread pattern. Record
the general qualitative characteristics for pattern uniformity
and wraparound (spreading ahead and/or to the sides of the
Turf Tender’s wheels).
We found that, initially, we needed to spread material from
the stationary position and, when done spreading, push the
material into a narrow row (long pile), running across the spread
area. Looking at the amount of material in the strip-pile is a
pretty good indicator of the distribution pattern. After a short
period of time you will be able to look at the distribution (where
it dropped) to determine how uniform the pattern is and
eliminate the need to pile up the material in a row.
As an example of the differences between the two test
methods’ results, we found that when we had an obvious W
spread pattern (heavy center and outside edges) using the
stationary testing method, the pan method was indicating that
we had a nearly perfect distribution. The problem is that the pan
method did not accurately reflect where the material was actually
deposited after it had hit the ground, bounced, rolled, and stopped.
Pattern Adjustments
The pattern below shows the optimum distribution of
material behind the spreader from one pass. On the next pass,
the operator should drive at the edge of the pattern, which
overlaps material to the center of the previous pass. This
results in a uniform distribution of material across the ground.
Most importantly, errors in driving cause minimal streaking
from double spreading or gaps. The problem is that it is very
hard to attain this pattern with broadcast spreaders.
Some spreader manufacturers or users prefer to have a
pattern like the following figure. This can give good results
but requires more precise driving to achieve the exact interval
needed. The pattern must be tested with pans to determine
the point half way from the edge to the corner. Then the driving
interval must be maintained or gaps and overspreading result.
26
The rectangular pattern is best for sand and requires perfect
driving to avoid gaps and overspreading. It is not
recommended.
The oval or rounded pattern is common to many spreaders
and can yield good results similar to the trapezoidal pattern.
The same discussion applies. To get it close to a pyramidal
pattern, increase the amount of release angle on the blades.
This should cause more material to fall directly behind the
spreader. Also, reducing the amount of hold angle should yield
the same result.
The following pattern results from excessive hold angle.
Too much material is staying on the blades too long. Reduce
the hold angle and change half the blades to a release angle.
This pattern may also be caused by too much hold on half
the blades. The heavy center may indicate excessively high
spinner speeds. From a safe distance, watch how material is
exiting the center of the spinners. If a lot of material is coming
off each spinner in the center after hitting the shield and
crossing over the center, the spinner speed is too fast. This is
due to material bouncing off the blades of the spinners rather
than siding along the blade. On the other hand, if the material
streams crossing from each side are colliding and dropping
straight down, the blades need to hold material a little longer.
If there is little crossing of material at the center, reduce the
hold angle to bring the edge humps toward the center.
OPERATION
ELECTRIC BRAKES
Overview
Most trailer-type Turf Tenders come equipped with electric
brakes. Electrically actuated brakes have several advantages
over other brake actuation systems.
1. They can be manually adjusted to provide the correct
braking capability for varying terrain and load conditions.
2. They can be modulated to provide more or less braking
force, thus easing the brake load on the towing vehicle.
3. They can provide braking independent of the tow vehicle.
APPLICATION RATES
Overview
Application rate refers to the amount of material spread
over a given area. Often it’s referred to pounds per acre or
1000 square feet.
To Achieve a Higher Application Rate:
1. Slow down the ground speed. This is the best option since
your spread pattern will not be affected.
2. Increase the rear gate opening. Doing this may affect your
spread pattern.
3. Decrease spinner speed (spread pattern width); then
decrease the driving interval (overlap). This may also
change the uniformity of spread.
To Achieve a Lower Application Rate:
1. Increase ground speed. This is the best option since your
spread pattern will not affected.
2. Decrease the rear gate opening.
3. Increase the spinner speed; then decrease the driving
interval (overlap).
Again, numbers 2 and 3 may affect the spread pattern.

Basics Of Operation
The electric brakes on the Turf Tender are similar to the
drum brakes on an automobile. The difference is that
automotive brakes are actuated by hydraulic pressure while
electric brakes are actuated by an electromagnet. Electric
brakes operate in the following manner:
1. When the electrical current is fed into the system by the
controller, it flows through the electromagnets in the
brakes.
2. The electromagnets are energized and are attracted to the
rotating armature surface of the drums which moves the
actuating levers in the direction that the drums are turning.
3. The resulting force causes the actuating cam block at the
shoe end of the lever to push the primary shoe out against
the inside surface of the brake drum.
4. The force generated by the primary shoe acting through
the adjuster link then moves the secondary shoe out into
contact with the brake drum.
5. As the current flow to the electromagnet is increased, it
causes the magnet to grip the armature surface of the brake
drum more firmly. This results in an increased pressure
against the shoes and brake drums.
CAUTION
The Turf Tender will not have the correct amperage
flow to the brake magnets to give you comfortable,
safe braking unless the proper brake system
adjustments have been made.
OPERATION
27
Varying load and driving conditions as well as uneven
alternator and battery output can mean unstable current flow
to your brake magnets. Therefore, it is imperative that a
properly modulated brake controller be used and the brakes
be maintained and adjusted according to the information in
this manual.
BRAKE CONTROLLER ADJUSTMENT
WARNING
Before making road tests, make sure the area is clear
of vehicular and pedestrian traffic.
It is important that the brake controller provide
approximately 2 volts to the braking system when the brake
switch is first activated. The longer the brake switch is held
in the ON position (either left or right of center), the voltage
to the brakes gradually increases up to a maximum of 12 volts.
If the controller voltage jumps immediately to a high voltage
output, even during a gradual stop, then the electric brakes
will always be fully energized during brake activation and
will result in harsh braking and potential wheel lockup.
Proper brake system setup adjustments can only be
accomplished by road testing. Brake lockup, grabbiness, or
harshness is quite often due to:
1. Improper setup of the Turf Tender.
2. Too high of a threshold voltage (over 2 volts).
3. Under adjusted brakes.
Before any brake setup adjustments are made (in the brake
control box on the right side of the Turf Tender), the Turf
Tender brake drums should be burnished-in by applying the
brakes 20-30 times at 15 mph and coming to almost a complete
stop. Allow ample time for brakes to cool between each
application. This allows the brake shoes and magnets to
slightly “wear-in” to the drum surfaces.
Operating the Electric Brake
The top switch on the left side of Turf Tender control box
controls the activation of the brakes. It is a three position
switch with the center position being the OFF position.
Turning the switch either to the left or right, activates the
brakes. The longer the switch is held in an ON position, the
more pressure the brakes exert. Only hold the switch in the
ON position until adequate braking is attained.
NOTE: Holding the switch in an ON position
gradually increases the voltage (stopping power) of
the brakes.
28
Tow the Turf Tender at slow speed (approximately 8 mph)
on a hard, level, and dry road surface. Activate the brake switch
and hold for a few seconds; then release. If the brakes lock
up, remove the brake control box cover on the right side of
the Turf Tender and back the GAIN knob off slightly. If the
brakes are weak, turn the GAIN knob up until the brakes don’t
quite lock up. Repeat the procedure until the brakes operate
properly. Place the cover back into position and secure.
WARNING
Gain should be turned down in wet or slippery
conditions. Gain should never be set to a level high
enough to cause the brakes to lock up. Skidding
wheels can cause loss of directional stability of the
Turf Tender and tractor possibly resulting in injury
or even death.
The GAIN control may need to be reset to adjust for
different load weights and terrain conditions. Braking
performance may be sluggish in subfreezing temperatures.
In subfreezing temperatures, allow adequate time for the
control to warm up prior to use.
OPERATION
MAINTENANCE
WARNING
After all repairs and/or adjustments, always test the
Turf Tender before operating. Failure to do may
result in injury or even death.
RUNNING GEAR (TRAILER-TYPE MODELS)
Wheels
There is very little chance of a problem with your wheels
unless you are driving on a flat tire or if the wheel bolts have
loosened. If a problem should develop with a wheel, remove
it; then repair or replace as needed.
Axles
Larger models of the Turf Tender have two (2) wheels on
each side of the Turf Tender that are attached to independent
“walking beam” axles. Smaller Turf Tender models have a
single, solid axle on each side. The axles, if maintained
properly, will give many years of service.
WARNING
Tire and wheel mounting and demounting can be
dangerous and must only be done by trained
personnel using proper tools and procedures.
Failure to comply with safety procedures and
information contained here can result in serious
injury or even death.
Tires
The tires on the Turf Tender are designed to provide good
flotation (less compaction) under normal circumstances. It is
important to check tire pressure on all tires periodically to
ensure they are properly inflated. Proper inflation will extend
wear and provide good flotation. The recommended tire
pressure operating range is 13-18 psi (90-124 kPa) for 26.5
in. tires and 15-22 psi (115-169) for 33 in. tires. Do not exceed
the maximum tire pressure listed.
WARNING
Operation of the Turf Tender with improperly inflated
tires could result in serious injury or even death due
to the potential rollover under certain conditions
such as operating on a hillside.
3. Using jack stands, support the frame so it is safe to work
beneath. Under no conditions should cement blocks
(cinder blocks) or unstable piles of wood blocks be used.
WARNING
Do not perform maintenance of any kind below the
Turf Tender unless it is properly secured and
stabilized.
4. Remove the wheel bolts; then remove the wheel.
5. Bring the wheel to a tire repair center to fix or replace the
tire.
NOTE: Due to the specialized equipment necessary,
tire removal, repair, and mounting should be only
performed by a tire repair service shop.
6. Place the wheel back into position; then install the wheel
bolts. Tighten until snug.
NOTE: Do not lubricate threads.
7. Using a crisscross pattern, tightening wheel bolts to 90
ft-lb (12.4 kg-m).
CAUTION
Do not under or over torque the wheel bolts.
Inappropriate wheel bolt torque will result in wheels
loosening and possibly falling off.
8. Remove the jack stands from beneath the Turf Tender;
then lower the jack.
CHANGING AN OUTSIDE TIRE
1. Empty all material from the hopper; then chock the
wheel(s) on the opposite side of the Turf Tender.
2. With the Turf Tender hooked to a tractor that has the
parking brake set, jack up the frame directly in front of
the axle mount.
NOTE: Wheel bolt torque must be checked every 10
hours after mounting a wheel until the bolts maintain
the proper torque.
CHANGING AN INSIDE TIRE (4-WHEEL MODELS)
Changing an inside tire is slightly more complicated than
changing an outside tire since it involves removing the
“walking beam” axle assembly and rolling it out from beneath
the Turf Tender.
1. Empty all material from the hopper; then chock the
wheel(s) on the opposite side of the Turf Tender.
2. With the Turf Tender hooked to a tractor that has the
parking brake set, jack up the frame directly in front of
the axle mount.
MAINTENANCE
29
The walking beam axles need regular greasing maintenance.
There are grease points on the front and rear of each axle
assembly. General lithium grease may be used for a lubricant.
See the lubrication schedule for proper lubrication application.
3. Using jack stands, support the frame so it is safe to work
beneath. Under no conditions should cement blocks
(cinder blocks) or unstable piles of wood blocks be used.
WARNING
Do not perform maintenance of any kind below the
Turf Tender unless it is properly secured and
stabilized.
4. Remove the walking beam axle mounting bolts and nuts
(front & rear). Roll axle assembly out to the rear.
5. Stand the axle assembly on end and remove the wheel
bolts; then remove the wheel.
6. Bring the wheel to a tire repair center to fix or replace the
tire.
NOTE: Due to the specialized equipment necessary,
tire removal, repair, and mounting should be only
performed by a tire repair service shop.
7. Place the wheel back into position; then install the wheel
bolts. Tighten until snug.
NOTE: Do not lubricate threads.
8. Using a crisscross pattern, tightening wheel bolts to 90
ft-lb (12.4 kg-m).
Wheel Bearings
The wheel bearings should be repacked with grease and
the seals inspected annually under normal use and conditions.
This procedure should be done more often if you are using
the Turf Tender every day or if working with extremely
abrasive materials or fertilizers.
NOTE: For Turf Tender models with only one wheel
on each side, ignore the steps referencing the
walking beam axles.
1. Empty all material from the hopper; then chock the
wheel(s) on the opposite side of the Turf Tender.
2. With the Turf Tender hooked to a tractor that has the
parking brake set, jack up the frame directly in front of
the axle mount.
CAUTION
Do not under or over torque the wheel bolts.
Inappropriate wheel bolt torque will result in wheels
loosening and possibly falling off.
9. Roll the axle assembly back under the Turf Tender and
install the eight bolts and nuts securing it to the frame.
Tighten the hardware to 75 ft-lb (10.3 kg-m).
10. Remove the jack stands from beneath the Turf Tender;
then lower the jack.
NOTE: Wheel bolt torque must be checked every 10
hours after mounting a wheel until the bolts maintain
the proper torque.
Axle Lubrication
Larger Turf Tender models come equipped with 2
independent walking beam axles. These axles allow the Turf
Tender to follow the contour of the ground better giving you
more stability and less chance of damaging turf.
30
3. Using jack stands, support the frame so it is safe to work
beneath. Under no conditions should cement blocks
(cinder blocks) or unstable piles of wood blocks be used.
MAINTENANCE
WARNING
Do not perform maintenance of any kind below the
Turf Tender unless it is properly secured and
stabilized.
4. Remove the eight walking beam axle mounting bolts and
nuts (four at the front and four at the rear). Roll axle
assembly out to the rear.
5. Stand the axle assembly on end and remove the wheel
bolts; then remove the wheels.
6. For each wheel bearing, remove the grease cap.
7. Bend the cotter key straight and remove; then remove
the spindle nut and washer.
8. Remove the hub from the spindle being careful not to
allow the outer bearing to fall out. The inner bearing will
be retained by the seal on the back side of the hub
assembly.
NOTE: It is important to protect the wheel bearing
bores (inside portion of the hub) from metallic chips
and contamination. Ensure the wheel bearing
cavities are clean and free of contamination before
installing the bearings and seal.
9. Using a suitable solvent, wash all grease and oil from the
bearings. Dry the bearing with a clean, lint-free cloth;
then thoroughly inspect each bearing. If any pitting,
spalling, or corrosion is present, the bearing must be
replaced.
NOTE: Bearings must always be replaced in sets of
inner and outer bearings.
10. Inspect the seal to assure that it is not nicked or torn and
is still capable of sealing the bearing cavity.
11. Pack the bearings with a Lithium complex NLGI No. 2
grease.
12. Assemble the hub (seal, bearings, spindle washer, and
spindle nut) back on the spindle being careful to not spill
grease on the outside of the spindle (backside) where it
could drop onto the brakes.
13. Rotate the hub assembly slowly while tightening the
spindle nut to approximately 50 ft-lb (7 kg-m); then loosen
the spindle nut to remove the torque. Without rotating
the hub, finger tighten the spindle nut until just snug.
Back the spindle nut out slightly until the first castellation
(slot) lines up with the cotter key hole and insert the cotter
key. Spread the legs of the cotter key.
NOTE: The nut should move freely with the only
restraint being the cotter key.
14. Install the spindle cap.
15. Install the wheels; then install the axle assembly. Refer
to the “Changing an Inside Tire” section for the procedure
and proper torque specifications.
Testing the Brake Controller
To perform a quick and easy test on the brake control, use
a 12-volt test light (not a voltmeter) and the following
procedure:
1. Connect the ground clip from the test light to a solid
ground (WHITE wire) and pierce the brake wire (BLUE
wire) with the point of the test light.
2. Activate the brake switch and hold. The test light should
get steadily brighter in intensity. Release the brake switch
and the test light should go out.
This test allows you to quickly see if the brake controller
is functioning properly. If the controller tests good with a test
light, but will not work properly with a Turf Tender connected,
check for a poor connection or broken wire.
NOTE: Minimum vehicle stopping distances are
achieved when the wheels approach lockup. Brake
lockup should be avoided as it results in poor
vehicle stability and control. Depending upon load,
driving surface, wheels and tires, not all brakes are
capable of wheel lockup under all conditions.
WARNING
Do not adjust the controller outside the parameters
outlined in these instructions.
General Maintenance
BRAKE ADJUSTMENT
Brakes should be adjusted: after the first 10 hours of
operation when the brake shoes and drums have “seated,” at
300 hour intervals thereafter, and as use and performance
requires. To adjust the brakes, use the following procedure:
1. Empty all material from the hopper; then chock the
wheel(s) on the opposite side of the Turf Tender.
2. With the Turf Tender hooked to a tractor that has the parking
brake set, jack up the frame directly in front of the axle
mount. Check that the wheel and drum rotates freely.
ELECTRIC BRAKES
Features
Electrically actuated brakes have several advantages over
other brake actuation systems.
1. They can be manually adjusted to provide the correct
braking capability for varying terrain and load conditions.
2. They can be modulated to provide more or less braking
force, thus easing the brake load on the towing vehicle.
3. They can provide braking independent of the tractor.
3. Using jack stands, support the frame so it is safe to work
beneath. Under no conditions should cement blocks
(cinder blocks) or unstable piles of wood blocks be used.
WARNING
Do not perform maintenance of any kind below the
Turf Tender unless it is properly secured and
stabilized.
MAINTENANCE
31
CAUTION
Do not lift or support the Turf Tender on any part of
the axle or the suspension system. All lifting and
support must be done on the frame directly in front
of the axle mount point.
4. Remove the cover from the adjusting slot on the bottom of
the brake backing plate.
5. Using a screwdriver or standard brake adjusting tool, rotate the
starwheel of the adjuster assembly to expand the brake shoes.
Adjust the brake shoes out until the pressure of the linings
against the drum makes the wheel very difficult to turn.
6. Rotate the starwheel in the opposite direction until the wheel
turns freely with a slight lining drag.
7. Install the cover and lower the wheel to the ground. Repeat
procedure on all brakes.
BRAKE CLEANING AND INSPECTION
The brakes must be inspected and serviced at yearly
intervals (more often as use and performance requires).
Magnets and shoes must be changed when they become worn
or scored thereby preventing adequate braking. Be sure to
clean the backing plate, magnet arm, magnet, and brake shoes.
Make certain that all the parts removed are installed in the
same brake and drum assembly. Inspect the magnet arm for
any loose or worn parts. Check shoe return springs, hold down
springs, and adjuster springs for stretch or deformation;
replace if required.
BRAKE LUBRICATION
Before assembling, apply a light film of Lubriplate or AntiSeize compound on the brake anchor pin, the actuating arm bushing
and pin, and the areas on the backing plate that are in contact with
the brake shoes and magnet lever arm. Apply a light film of grease
on the actuating block mounted on the actuating arm.
CAUTION
Do not get grease or oil on the brake linings, drums,
or magnets.
MAGNETS
The electric brakes are equipped with high quality
electromagnets that are designed to provide the proper input
force and friction characteristics. The magnets should be
inspected and replaced if worn unevenly or abnormally. Check
the magnets for wear using a straightedge.
32
Even if wear is normal as indicated by your straightedge,
the magnets should be replaced if any part of the magnet coil
has become visible through the friction material facing of the
magnet.
NOTE: It is recommended that the drum armature
surface be re-faced when replacing magnets.
Magnets should be replaced in pairs - both outer sets and/
or both inner sets. Use only genuine DAKOTA replacement
parts when replacing the magnets.
SHOES AND LININGS
A visual inspection of your brake linings will indicate if
they are in need of replacement. Replacement is necessary if
the lining is worn to 1/16 in. (1.5 mm) or less, contaminated
with grease or oil, or abnormally scored or gouged. Hairline
heat cracks are normal in bonded linings and is not a cause
for concern. To retain the “balance” of your brakes, it is
important to replace both shoes on each brake and both brakes
of the same set (inner and/or outer).
Troubleshooting
Most electric brake malfunctions that cannot be corrected
by either brake or controller adjustments, can generally be
traced to electrical system failure. Mechanical causes are
ordinarily obvious, i.e. bent or broken parts, worn out linings
or magnets, seized lever arms or shoes, scored drums, loose
parts, etc. A voltmeter and ammeter are essential tools for
proper troubleshooting of electric brakes.
MEASURING VOLTAGE
Brake system voltage is measured at the magnets by
connecting the voltmeter to the two magnet lead wires at any
brake. This is accomplished using pin probes inserted through
the insulation of the wires dropping down from the chassis.
The engine of the towing vehicle should be running when
checking the voltage so that low battery voltage will not
adversely affect the readings.
Voltage in the brake system is designed to modulate (begin
at 0 volts and, as the brake switch is held in the ON position,
gradually increase [modulate] to about 12 volts). If no
modulation occurs (immediate high voltage applied to the
brakes just when the controller begins to apply voltage), adjust
and/or troubleshoot the brake system.
The threshold voltage of the controller is the voltage
applied to the brakes when the controller is first applied. The
lower the threshold voltage, the smoother the brakes will
operate. Too high of a threshold voltage (in excess of 2 volts
as quite often found in heavy duty controllers) can cause
grabby, harsh brakes.
MAINTENANCE
MEASURING AMPERAGE
System amperage is the amperage being drawn by all
brakes on the Turf Tender. The engine of the towing vehicle
should be running when checking amperage.
Measure system amperage at the BLUE controller wire
(the output to the brakes). The BLUE wire must first be
disconnected and the ammeter put in series into the line. Make
sure the ammeter has sufficient capacity to handle the current
draw of about 6 amps. To prevent damaging the ammeter, be
sure to observe polarity.
Individual amperage draw can be measured by inserting
the ammeter in the line at the magnet you want to check.
Disconnect one of the magnet lead wire connectors and attach
the ammeter between the two wires. Make sure that the wires
are properly connected and sealed after the testing is
completed.
HOPPER CONVEYOR BELT
Belt Adjustment
Due to stretching of the belting material with use, it will
be necessary to periodically tighten the conveyor belt. Pressure
on the belt and warm temperatures will increase the frequency
of belt tightening. The belt should be loosened if the Turf
Tender will not be used for an extended period of time or will
be moving to a colder operating temperature due to seasonal
or geographic changes.
NOTE: If the belt was loosened for storage or any
other reason, the belt will need to be tightened
before using the Turf Tender.
CAUTION
Always tighten the belt at the front roller. Adjusting
the rear roller will affect the material placement on
the twin spinners and may affect belt tracking.
To tighten the main conveyor belt, use the following
procedure:
1. On drive motor side of the Turf Tender, loosen the two
nuts securing the drive motor mount to the hopper frame.
2. Loosen the jam nut on each of the tensioning bolts.
By far, the most common electrical problem is either
low or no voltage and amperage at the brakes. Common
causes of this condition are:
1. Poor electrical connections
2. Open circuit(s)
3. Insufficient wire size
4. Broken wires
5. Damaged circuit breaker (use of a fuse is not recommended).
6. Improperly functioning switch, controller, or resistors

or partially shorted circuits (indicated by abnormally high
system amperage). These are occasionally the most difficult 3. Using a ¾ inch wrench, turn each tensioning bolt

Belt Replacement
SPLICED BELT
If it becomes necessary to replace the spliced main
conveyor belt, use the following procedure:
NOTE: DAKOTA sells replacement kits composed
of a spliced belt and wire splice pin. The splice pin
connects the two halves of the splice.
1. Run the conveyor until the belt splice is close to the front
of the Turf Tender; then shut the vehicle’s engine off.
WARNING
Make sure the vehicle’s engine is not running before
starting the belt replacement procedure.
2. Loosen the jam nut securing each of the four belt
tensioning bolts (on both sides, front and rear).
3. On drive motor side (front and back) of the Turf Tender,
loosen the two nuts securing the drive motor mount to
the hopper frame.
4. Loosen the four belt tensioning bolts (one on each side
of both the front and rear rollers). Make sure you loosen
each tensioning bolt the same number of turns.
5. Rotate the loose belt until the splice is at the front of the
Turf Tender.
6. Uncrimp or cut off the end of the belt splice securing the
hinge pin.
7. Using a steel rod, drive or push the hinge pin out of the
splice. The steel rod must be long enough to reach across
the entire belt.
NOTE: Once the hinge pin has started to exit the
splice, it may be easier to remove by pulling on it
with a pair of locking pliers.
8. Remove the old belt; then place the new belt into position
making sure the cups on the topside of the new belt have
the open part of the “C” facing to the rear of the Turf
Tender.
9. Align the splices of the new belt; then run the steel rod
(used to remove the hinge pin) through the splice.
10. Fully insert the new hinge pin into the splice. Use the
hinge pin to push the steel rod out of the splice.
NOTE: The steel rod provides splice alignment.
11. Making sure the hinge pin does not stick out beyond either
edge of the belt, crimp both ends of the splice so the hinge
pin cannot work its way out of the splice.
12. Starting at the rear roller, tighten the tensioning bolts for
the rear roller until the horizontal distance from the flat
of the belt to the vertical wall of the chute behind the
rear roller is 5 1/4 in. (13.3 cm). This is a critical distance
that provides both alignment (tracking) of the belt and
spread pattern control. Measure this distance at both the
left and right sides of the belt.
13. Finish tensioning the belt at the front rollers by equally
tightening the front tensioning bolts. Using a torque
wrench, tighten each of the front tensioning bolts to
approximately 35 ft-lb (4.8 kg-m). This is a “ballpark”
value since the belt will expand and contract with
temperature changes. Ultimately, the best method of
tensioning is to have it just tight enough to not slip while
unloading material.
14. Test the belt for proper alignment by running the conveyor.
Make small adjustments to the rear roller tensioning bolts
for this belt alignment fine tuning.
15. When the alignment and tensioning are complete, secure
the adjustment by tightening the four jam nuts against
the frame and the four drive motor mount nuts (two for
each drive motor).
ENDLESS BELT
Before starting to replace the belt, make sure that there is
adequate work space around the Turf Tender. Open and secure
the front and rear gates. If equipped with a side conveyor,
swing the side conveyor to the operating position for full
access to both sides of the Turf Tender.
WARNING
Always shut off the tractor engine when performing
maintenance on the Turf Tender.
To replace the belt, use the following instructions:
1. Remove the spinner assembly; then remove both fenders.
2. Remove the front and rear hydraulic motors and mounting
brackets.
Note: The hydraulic hoses do not have to be
disconnected from the motors.
34
MAINTENANCE
3. Loosen the jam nut securing each of the four belt
tensioning bolts (on both sides, front and rear); then loosen
the adjusting bolts.
4. Pull the belt to the rear and remove the rear roller; then
pull the belt forward and remove the front roller.
5. Remove the diamond wiper located in the center of the
hopper.
Note: The diamond wiper is located between the
frame of the machine under the fender. It is mounted
with the UHMW plastic facing downward.
6. Remove the bolts holding the belt run in place.
7. Set two sawhorses in front of the hopper and pull the belt
and belt run out together. If it seems tight, the belt may
be removed from the front as well.
8. Roll the belt run over on its side and remove the old belt
from the belt run.
11. Gather all slack belting on both the top and bottom and
pull to the rear.
12. On both sides of the belt run, rub a small amount of lithium
grease along the edge to keep the belt run from sticking
when sliding it back into position.
13. Together, slide the belt and belt run into the frame.
14. Line up the belt run with the guide pins (two in front and
two in the rear).
15. Start, but do not tighten, all of the belt run bolts.
16. Inspect each roller to be sure that it is centered in the
conveyor. Each roller is adjusted with spacers on the
motor side. All slack must be pulled to the motor side
when aligning the roller. After making sure the roller is
centered, place the front roller assembly into position.
17. Pull the slack of the belt to the rear and under the belt
run; then place the rear roller assembly into position.
NOTE: To install the roller, insert the roller through
the belt at an angle.
18. Install and secure the diamond wiper making sure the
UHMW plastic facing downward.
19. Tighten both the front and rear rollers until the belt is
snug (not tight). Make sure to tighten each side of both
rollers equally.
20. Check to ensure that the belt feels firm when you push
down on the inside of the conveyor. The tightness of the
belt can be adjusted when tightening the bolts securing
the belt run.
21. Tighten all of the bolts securing the belt run. Monitor the
tightness of the belt inside the conveyor and adjust as
needed during tightening.
22. Install the spinner assembly. Final adjustment of the
rollers cannot be made until the spinner assembly is
installed. Tighten the tensioning bolts for the rear roller
until the horizontal distance from the flat of the belt to
the vertical wall of the chute behind the rear roller is 5
1/4 in. (13.3 cm). If you are not using the spinner package,
make sure that rollers are adjusted equally on both sides.
23. After completing the rear roller adjustment and the roller
to spinner setting, finish tightening the belt at the front
roller only. Secure each roller adjustment by tightening
the jam nuts on the adjusting bolts.
24. Install the hydraulic drive motors with mounting brackets;
then install the fenders. Tighten all hardware securely.
SIDE CONVEYOR
Belt Adjustment
On occasion, the tension on the conveyor belt will need to
be adjusted. The belt should be loosened when the Turf Tender
will not be used for an extended period of time. The belt will
need to be tightened after extended periods of inactivity, or
when it becomes loose. Heavy use, as well as hot weather,
could loosen the belt due to normal stretching of the belting.
The belt can only be adjusted at the discharge end of the
conveyor.
WARNING
Always shut off the tractor engine when performing
maintenance on the Turf Tender.
9. Slide the new belt over the belt run. Make sure the cups

1. Loosen the four bolts (two above and two below) securing
the motor mount to the frame.
2. Loosen the jam nut on right-hand adjusting bolt.
3. Adjust the adjusting bolts as needed to either loosen or
tighten the belt. Make sure both sides are adjusted equally.
4. Test the conveyor for proper tension and to be sure the
belt is properly aligned.
5. Tighten jam nut on the right hand adjusting bolt; then
tighten the motor mount bolts.
6. Run the conveyor for short period to make sure that the
belt stays on track.
It is important that the belt always runs in the proper track.
If the belt is allowed to run off track to either side it could
become jammed or could wear the belt out prematurely.
Belt Replacement
If it becomes necessary to replace the belt, use the
following procedure:
1. Loosen the four bolts (two above and two below) securing
the motor mount to the frame; then loosen the jam nut on
right-hand adjusting bolt.
3. Adjust the adjusting bolts to loosen the belt. Make sure
both sides are adjusted equally; then remove the splice
pin.
4. Pull the old belt out of the conveyor.
5. Starting on high end of conveyor, thread the new belt
into the conveyor. Make sure V-belt on the inside of the
conveyor belt fits in V on roller and that the belting cups
are positioned with their open end facing the discharge
end of the conveyor.
6. Connect the two ends of the belt with the splice pin; then
crimp the ends of the lacing to keep the pin from sliding out.
7. Tighten the belt using the belt tightening procedure. Make
sure the belt is tracking correctly.
2. Regularly clean and wash the hopper and conveyor
especially if hauling potentially corrosive materials
such as fertilizer.
3. Keep belt tight when in use.
4. Loosen belt at the front rollers when Turf Tender is not
going to be used for an extended period of time. The
belt contracts a significant amount as its temperature
drops so loosening the belt for winter storage is
important.
5. Periodically check belt for tears and wear.
6. Never allow hydraulic fluid to come in contact with
the belt. It is made of PVC which provides resistance
to fertilizers and other agricultural chemicals but has
little resistance to hydraulic fluid.
DUAL SPINNER SPREADING SYSTEM
Regular Maintenance
Maintenance of the dual spinner system consists of
greasing the bearing on each spinner shaft. There is a total
of two (2) grease points on the spinner package (consult the
lubrication chart for recommended lubrication schedule).
CAUTION
Before operating, always test the Turf Tender after
either repair or adjustment.
Regular Maintenance
Regular maintenance of the conveyor system consists of:
1. Regular greasing of the roller’s bearings (consult the
lubrication chart for recommended lubrication schedule).
There is one grease point on each side of both the front
and rear rollers.
36
Periodically check the hydraulic hoses for worn areas
and other unsafe conditions (cracks or leaks). This should
be part of the safety walk around each time before using
the Turf Tender. Pinhole leaks under pressure can pierce
skin and inject hydraulic oil under your skin. Never handle
hoses while the hydraulic system is pressurized.
MAINTENANCE
Whenever changing spinner blades, thoroughly clean the
spinner shafts before installing a different set of spinners.
This prevents a buildup of dirt, grease, and other materials.
After cleaning, apply Anti-Seize to the shafts.
ELECTRICAL SYSTEM
NOTE: Electrical schematics are available upon
request. If problems are experienced with a control
box, contact either your dealer or Dakota Peat.
Overview
The Turf Tender electrical system (on all models except
the self-contained models which obtains its power from the
lighting coil of the engine) obtains its DC electrical power
from the vehicle’s battery and/or alternator. A power cord is
supplied with the Turf Tender to carry the power from the
vehicle to the control box; then back to the Turf Tender. The
power cord should be installed as a permanent addition to the
vehicle. The power cord is plugged into the control box.
Switches and Fuses
Electrical control of actuators (brakes, electric motors and
hydraulics) is through the use of ON-OFF type switches
located in the control box.
Electric-control models (as opposed to the Manual-control
models) use electronic controls for the regulation of the hopper
conveyor and spinners hydraulic motor speeds. These are
normally set in a specific position during operation and the
switches for each turn the electronic controls ON and OFF.
All branch circuits leading to controls and actuators are
protected by either fuses or circuit breakers. On 440 and 420
models, the fuses are located in the bottom of the control box.
All other models have a controller/fuse box located on the left
side of the Turf Tender. Each function of the Turf Tender is fused
separately. If a fuse blows, be sure to identify and correct the
cause of the blown fuse prior to replacing the fuse. Simple
replacement of a fuse normally results in another blown fuse.
Access to the controller/fuse box should be limited to
replacement of a blown fuse after correcting the cause. Located
within the controller/fuse box are adjustments that may be
made to the valve bank controls. These controls have been
preset at the factory and should not be changed unless
instructed to do so by the factory.
Wiring
All wiring conforms to SAE J1128 standards low tension,
PVC insulated, stranded copper wire. The PVC insulation
has a 176ºF (80ºC) temperature rating. It is important that
wires not be routed through areas having high temperatures.
Exposed wires are also encased in black, abrasion-resistant
looming wherever possible. The working temperature range
of the loom is -34º to 200ºF (-34º to 93ºC). Again, since this
a low temperature plastic, it is important that the wires are
not routed near areas with high temperatures.
The connectors used on the Turf Tender are either flat
automotive-type connectors or round “cannon” connectors.
The control box may contain extra wires for options not
ordered. The connectors are designed to “break away” if the
wires are pulled from the control box. Should damage result
to either a connector or wiring harness, a genuine DAKOTA
replacement part should be ordered and installed.
Electric Hydraulic Valves
Electric actuated hydraulic valves are used for the control
of all hydraulic circuits. The valves are a replaceable but not
repairable item. Depending upon the style, the amperage draw
of each solenoid is rated at a maximum of either 1 or 3 amps.
CAUTION
Always replace fuses with fuses of the same
amperage. Any adjustments within the controller/
fuse box must be pre-authorized by the factory.
MAINTENANCE
37
Vibrator Motor
The vibrator uses a carbon brush-type electric motor. The
brushes in the vibrator motor are a replaceable item, and after
extended use, may need to be replaced.
NOTE: The position of the counterweights inside
the vibrator have been preset from the factory and
should not be changed.
Problem Diagnosis And Repair
Diagnosing electrical system problems involves identifying
the features, components, or functions which are not working
properly; then tracking and testing the system back from there.
A multimeter and two jumper wires (preferably with alligator
clips on the ends) will be needed for these tests. Most tests
will be checking for the presence of voltage. Make sure the
multimeter is set to DC volts (not amps or ohms) prior to
conducting these tests.
COMPLETE SYSTEM FAILURE
Should the whole system appear to be inactive, including
the vibrator and electric front door, when the vehicle’s engine
is running and supplying electrical and hydraulic power,
troubleshoot the electrical system using the following steps.
The vehicle’s transmission must be in the neutral position
and the parking brake set. All tests are to be performed with
the engine off so that there is no chance of accidental
engagement during the tests.
WARNING
Never perform any maintenance or troubleshooting
unless the vehicle’s engine is off and the parking
brake set.
1. Turn the master switch on the control box (if equipped)
to the ON position. The red light on the control box should
illuminate. If the red light illuminates, the electrical
problem is between the control box and the Turf Tender.
If the light does not illuminate, the problem is either with
the electrical system of the vehicle or in the wiring leading
to the control box.
2. Check the main power harness connector at the control
box making sure it is clean and making good contact.
Clean or replace as necessary.
3. Using a multimeter set in the 12 volts DC range, check
the voltage at the end of the main power wiring harness.
Being sure to observe polarity connect the red test lead
from the meter to the red (+) wire and the black test lead
to black. Voltage greater than 11 volts should be present.
Low voltage indicates a problem with either the vehicle’s
battery or the connections of the main power wiring
harness. If there is no evidence of damage to the power
wiring harness and the connections are good, connect the
main power wire harness to the control box.
NOTE: If there is a reading of zero volts, move the
negative lead from the power wire harness to a bare
spot on the chassis of the tractor which will give a
good chassis ground. Paint is a poor conductor of
electricity. If a voltage is present, there is a problem
with the ground (black) wire or it’s connection to
the battery. Check the connection. If the connection
is not the problem, replace the power wire harness.
4. Open the control box, and check the voltage between the
chassis ground screw (located on the inner left wall) and
the power lead (located on the fuse block). If no voltage
is detected, but voltage was present at the end of the main
power harness, the problem is in the power pigtail of the
control box. Repair or replace as necessary.

MAINTENANCE
If after uncoupling the Turf Tender on trailer-type models,
it has happened that the operator drove off without
disconnecting the power cable from the tractor and forgetting
to return the control box to its storage location the connector
may get damaged.
2. If all functions except the vibrator work, the problem
is most likely with the small, circular cannon plug connector
portion of the wiring harness. Check the connections to ensure
they are fully connected, clean, and not damaged.
If the vibrator still does not work, check the voltage at the
two pins exiting out of the smaller cannon plug connector on
the control box. Make sure they are clean and not damaged.
5. Check the voltage between the control box’s chassis
ground screw (on the left side wall) and the brass buss
bar running across the top of the fuse block. If there is no
voltage detected, check all connections.
WARNING
Prior to closing the control box lid, make sure the
rubber sheet is laying over the top of the fuse block.
This serves as an insulator to keep the control wires
from rubbing on the fuse block and possibly
shorting. Failure to do so could result in loss of
control, injury, or even death.
FAILURE OF SPECIFIC FUNCTIONS
1. If all functions except the vibrator do not work, there
is a problem in either part of the large circular “cannon” plug
connector portion of the control box to the Turf Tender wiring
harness. Check the connections to ensure that they are fully
connected, clean, and not damaged.
If no voltage is detected while the vibrator switch is ON,
open the control box (or controller/fuse box) and check the
fuse. Replace as needed.
If the fuse is working properly, check the voltage at the switch
terminal while it is in the ON position. If no voltage is detected,
replace the switch. The switch is rated at 12 volts DC, 20 amps.
Do not use an underrated switch as a replacement.
Check the voltage at the rear end of the wiring harness
coming from the control box. If no voltage is detected, the
problem is most likely with the wiring harness coming from
the control box. Repair or replace as necessary.
If the wiring harness checks out, visually check all wires
going back through the Turf Tender including the connectors
behind the valve assembly. If all the wires and connections
appear good, there may be a problem with the vibrator’s motor.
Prior to removal, check for voltage at the motor. The brushes
in the motor are consumable parts and are replaceable. Use
only original DAKOTA replacement parts.
3. If an individual function does not operate, perform
the same tests listed above. The solenoid(s) on the hydraulic
valve assembly are not serviceable parts and, although rare,
may need to be replaced.
NOTE: The retaining nut on the top of each hydraulic
valve section requires only firm hand tightening.
Application of excessive force will result in damage
to the valve.

HYDRAULIC SYSTEM
All components use either an O-ring boss or 37° flare
hydraulic fittings. Do not use pipe-threaded hoses or fittings
for replacements. Do not use Teflon tape or pipe thread
compound. These are not helpful and may cause damage to
the system.

Operation
The hydraulic system providing hydraulic fluid to the Turf
Tender should be filled with premium grade hydraulic fluid
per the recommendations of the vehicle’s owner’s manual.
The oil should be good for at least two years unless one of the
following problems occur:
1. If the reservoir is contaminated with excessive water
or dirt. Hydraulic fluid can hold more than 20% water in
solution. Usually at these high levels, the fluid will appear
milky. A quick test for water at lower concentrations may
be performed outside with a hot (>300°F) sheet of steel.
With the sheet heated, drop a small amount of hydraulic
fluid in the center of the sheet. If it sputters there is a
significant amount of water in the fluid and the fluid
should be replaced.
2. If the oil has been overheated [above 190° F (87°C)].
The oil will have a foul odor. Do not use oil that has been
overheated. The lubricating properties have been
destroyed and acids and varnish have been created by
oxidation.
3. If a pump or motor has had a catastrophic failure
resulting in metal fragments and particles entering the
fluid. These particles may cause the replacement
components to fail before the filter cleans up the system.
The filter in a hydraulic system does not filter out 100%
of all particles as the fluid passes through it.
After any of the above have occurred, the entire system
should be drained, cleaned, and filled with new fluid. A new
filter should always be installed after any maintenance to the
hydraulic system.
FITTINGS AND HOSES
All hoses and fittings are rated for 3000 psi or greater. All
replacement fittings and hoses must meet or exceed this
specification.
40
Hydraulic flow is required to operate the Turf Tender
functions. With all Turf Tender control switches off, the oil
circulates from the hydraulic source through the electric
control valves and back to the source with little system flow
restriction.
When the conveyor switch is activated, a portion of the
oil is directed to the conveyor motor and the remainder is
sent to the exhaust port of the valve. The motor return flow
is combined with the exhaust flow and the full flow is sent to
the spinner valve.
When the spinner switch is activated, a portion of the oil
is directed to the spinner motors in series and the return flow
is again combined with the exhaust flow and returned to the
tractor.
In all switch positions, the tractor relief valve can limit
the maximum pressure by dumping oil to the tractor reservoir.
This should happen only during a malfunction wherein the
desired flow path is blocked. The engine must be shut down
immediately as all the engine power is being turned to heat
and being absorbed by the hydraulic fluid. The cause of the
blockage must be identified and eliminated before the engine
is restarted.
A few newer model tractors are capable of producing very
high working pressures. In case an operator reverses the flow
of the hydraulic fluid by hooking up hoses backwards or by
reversing the tractor controls, a check valve has been added
to the return (exhaust) line to prevent reverse pressurization
and potential failure of seals on the control valve assembly.
This check valve hangs down off the left end of the control
valve assembly.
Hydraulic Valves
The hydraulic valve package is operated by 12 VDC
solenoids which are controlled by toggle switches in the
control box. The speed of the spinners and the conveyor belt
are adjusted by the rotating knobs.
Hydraulic Schematics
NOTE: Hydraulic schematics are available upon
request.
MAINTENANCE
STORAGE
Before storing the Turf Tender for an extended period of
time, such as over the winter, it is important to make sure the
Turf Tender is in good condition and all maintenance is
complete.
Wash the Turf Tender thoroughly to make sure you have
removed all corrosive or potentially corrosive materials. Let
the Turf Tender dry completely, especially if you will be
covering the Turf Tender.
Grease all points that need to be greased. This is a good
time to do the annual repacking of the wheel bearings.
Otherwise it will need to be done when you remove the Turf
Tender from storage.
Relax the tension on the conveyor belt.
Check the air pressure on all tires and fill if needed to
maintain recommended pressure. It is usually a good idea to
make any needed repairs before storing the Turf Tender. If all
repairs and maintenance is completed before storing the Turf
Tender, it will be ready for use immediately when you need
it.
If you have taken the time to complete these season storage
operations, removing the Turf Tender from storage will be
easy. Do a safety inspection as you would any time you hook
up to the Turf Tender.
If you did not have time to store your Turf Tender properly
you may have to do repair work on the Turf Tender before
you can use it. Grease any points that need to be greased.
Repack the axle bearings if this was not done. Check the tire
pressure and fill the tires. Do a complete safety inspection of
the Turf Tender to spot any potential problem areas. Fix any
problems that you find. Tighten the conveyor(s) to the proper
tension. Hose off the layer of dust that has collected on the
Turf Tender. The Turf Tender should be ready to use.

Top Dressing Material
In cooperation with several universities and soil testing
laboratories nationwide, Team DAKOTA has developed a
highly concentrated organic material called Dakota Peat.
Dakota Peat is formed principally from partially decomposed
reeds, sedges, marsh grasses, and other associated plants. These
plants have a unique cellular structure that resists further
decomposition. Cells with exceptionally high plant feeding
ability are essential for successful development of a plant’s
root system and the right balance of air and water. This makes
it an ideal soil conditioner and growing medium.
Dakota Peat is the finest quality peat from selected deposits,
carefully processed to maintain its excellent, agronomic
horticultural attributes. It is naturally dried by summer sun and
winds; then gently packaged by vibrating machines to preserve
its unique cellular structure. Dakota Peat is high in organic
content, odorless, and free of harmful substances.
Material Recommendations for Use in Greens,
Tees Boxes, and Sports Field Maintenance
The Agronomists at Dakota Peat and Equipment have
performed thousands of hours of research into top dressing
materials and have many recommendations for maintaining a
quality green and healthy turf. One such recommendation is
using a mix of USGA spec. sand and Dakota Peat in varying
ratios for all situations of green and tee box maintenance.
Dakota Peat blends can be utilized in sand-to-peat ratios from
80/20 to 90/10 (depending upon the needs of various turf
problems or objectives). Simply stated, the facts are that this
combination of components will enhance the quality,
resiliency and playability of all surfaces and subsurfaces for
future use. This applies to normal top dressing, top dressing
prior to over-seeding, and top dressing after coring or other
soil tillage practices. Using Dakota Peat/sand blends also helps
mend the problem spots that may show up on all courses and/
or fields from time to time.
Dakota Peat is the “one” amendment which virtually fulfills
all dressing needs for healthy growth and maintenance of golf
and sports turf. What makes Dakota Peat different from other
peat materials and necessary for sand blends? We believe the
following points will explain the benefits of Dakota Peat.
When used with a tested, spec. sand, the resulting Dakota
Peat/sand blend increases the water holding capacity of
the sand while allowing excellent water infiltration and
air exchange for optimum root growth and turf health.
The Dakota Peat/sand blend retains fertilizer and pesticides
in the upper soil horizon thereby maximizing usage and
absorption by the turf and target pests. This limits chemical
runoff and leaching potential creating a fertilizer and
pesticide cost savings while reducing environmental
responsibilities. This increase in retention is due to the
unique CEC (cation exchange capacity) of Dakota Peat
which greatly increases the blend’s capacity for stabilization
of leachable inputs and its water holding capacity.
The “near neutral” pH of Dakota Peat continues to provide
the best environment for microbial activity that decomposes
thatch. This reduction in thatch keeps the turf as healthy as
possible since (as we all know), thatch ties up fertilizer,
prevents water infiltration, and is a huge disease “reservoir.”
Thatch also reduces root mass due to poor gas exchange.
Even if using an aggressive aeration program, Dakota Peat/
sand blends increase positive results by increasing the ability
of the “sterile” sand to hold more fertility and water without
inhibiting air exchange and water infiltration.
The humic acid content of Dakota Peat aids in the gas
exchange through the soil surface plus water infiltration
by promoting soil particle aggregation. Its fulvic acid
content helps stimulate root growth into core areas and
also into any new root zones.
Ideal particle size and density allows the Dakota Peat to
become “part” of the sand since most of the particles fit
the profile of the sand and stay there.
