General Hazard Information
No accident-prevention program can be successful without the wholehearted cooperation of
the person who is directly responsible for the operation of the equipment.
A large number of accidents can be prevented only by the operator anticipating the result
before the accident is caused and doing something about it. No power-driven equipment,
whether it be transportation or processing, whether it be on the highway, in the field, or in
the industrial plant, can be safer than the person who is at the controls. If accidents are
to be prevented--and they can be prevented--it will be done by the operators who accept
the full measure of their responsibility.
It is true that the designer, the manufacturer, and the safety engineer can help; and they will
help, but their combined efforts can be wiped out by a single careless act of the operator.
It is said that, “the best kind of a safety device is a careful operator.” We, at Unverferth
Mfg. Co., Inc. ask that you be that kind of operator. REMEMBER:
THINK SAFETY
A CAREFUL OPERATOR IS THE
BEST INSURANCE AGAINST AN
ACCIDENT!
SIGNAL WORDS
INDICATES AN EXTREMELY HAZARDOUS SITUATION OR ACTION THAT WILL RESULT IN
SERIOUS INJURY OR DEATH.

Hitching to Tractor
Drawbar Connection
This cart is intended to be hitched to a tractor drawbar. Do not attempt to hitch to any other location
on the tractor other than the drawbar.
The cart is equipped standard with a single tang
hitch. A hitch pin between 1 1/2” or 2” diameter
must only be used with a hammer strap bolted to
the tractor drawbar.
NOTE: The use of a smaller diameter hitch pin will result in additional clearance between
the hitch and pin. This additional clearance may cause accelerated pin wear, tractor and cart
hitch wear, along with more pronounced jolting from the cart during transport operation.
•
DO NOT STAND BETWEEN THE CART AND TRACTOR WHEN HITCHING. ALWAYS ENGAGE PARKING BRAKE AND STOP ENGINE BEFORE INSERTING HITCH PIN.
After inserting drawbar pin, secure drawbar pin with a locking device to help prevent uncoupling
during use.
Jack Usage
•
Unhitching a loaded cart can cause serious injury or death due to
the tongue rising or falling. Always have a loaded cart attached to a
tractor. The jack is intended to support an empty cart only.
Use jack to support an empty grain cart, never a loaded grain cart. Always have a loaded
grain cart hooked to tractor.
•
Mount jack in storage location indicated after cart is hitched to tractor.

•
ALWAYS USE TRANSPORT CHAIN WHEN TRANSPORTING IMPLEMENTS. FAILURE TO USE A TRANSPORT CHAIN COULD CAUSE PERSONAL INJURY IF CART BECOMES DISENGAGED.
Always use intermediate chain support when
connecting the grain cart directly to a tractor.
DO NOT use the intermediate chain support as
the chain attaching point. FIG. 2 shows how
the transport chain must be installed between
the tractor and grain cart.
Transport chain should have a minimum rating
equal to the gross weight of the implement and all
attachments. Use only ASABE approved chains.
Allow no more slack in the chain than necessary to
permit turning.

Parker 742/842 — Operation
Hitching to Tractor (continued)
Clean hydraulic hose couplers before connecting to the tractor. For convenience, it is recommended to connect the flow door circuit hoses to tractor implement coupler #1, auger spout
circuit hoses to coupler #2, and attach auger fold circuit to coupler #3.
This unit is equipped with color bands attached to the hydraulic hoses. This will help in
identifying the hose function and correct hook up.
Green: Raise and Lower Auger
Red: Flow Door Open and Close
Yellow: Spout In and Out
After initial set up or replacement of any hydraulic component on the cart, air must be removed from the cart’s hydraulic system.
Route hoses away from areas that may cause abrasion or kinking of hoses during operation.
Before disconnecting hoses from the tractor, relieve pressure. See the tractor operator’s
manual for the proper procedure to relieve the pressure. Shut off engine and apply parking
brake before disconnecting hoses. Install couplers into storage slots provided.
Hydraulic Connections for Hydraulic Drive
It is possible that the tractor utilizes more than one pump to achieve higher hydraulic flow rates.
To maximize hydraulic flow to auger hydraulic drive motor, refer to tractor’s Operator’s Manual to
determine which couplers should be used to achieve maximum flow. A flow test by your dealer’s
tractor technician can be performed and is recommended to assure maximum flow without
exceeding motor limits.
A case drain hose is supplied with the 100 gpm kit and can be used.
•
The case drain line is to be connected to the tractor’s low pressure return line ONLY! DO
NOT connect to the hydraulic couplers! DO NOT plumb both case drain and hydraulic drive
return lines to low pressure return. Pressure in return lines will back flow into case drain and
shorten motor life.
To avoid thermal shock, maintain a temperature difference less than 50 degrees between
the tractor’s hydraulic fluid and the motor’s hydraulic fluid. With the flow door closed, run
the motor in very short intervals (bursts with 15 second pauses) or low hydraulic flow rate
at startup, in order for hydraulic oil to slowly exchange colder oil in the motor with warmer
oil from the tractor. Particularly advised on cold days and/or first loads of the day.

Electrical Connections
This cart is equipped with a seven-pin SAE connector plug which will connect with the receptacle
found on most newer tractors. If your tractor does
not have this type of receptacle, an SAE J-560
seven-point socket can be purchased from your
Parker dealer (Part number 92824).
FIG. 4
The wiring schematic for this cart, shown in the MAINTENANCE section, complies with ASABE Standards. Always verify correct electrical function before using this cart.
Compliance with all lighting and marking laws is the responsibility of the operator at the
time of travel.
See federal regulation 49 CFR 562; available at www.govinfo.gov for US federal law requirements.
See your Unverferth dealer for additional brackets, reflectors, or lights to meet your requirements.

Towing
This cart is not equipped with brakes. Ensure that the towing vehicle has adequate weight
and braking capacity to tow this implement. See the towing vehicle manual for towing capacity. Never tow a loaded grain cart over public roads.
Do not exceed 10 mph during off-highway travel. Do not exceed 8 mph when cart is fully
loaded.
Secure drawbar pin with a locking device and lock tractor drawbar in centered position.
Connect the PTO driveshaft to the tractor.
Secure transport chain to tractor chain support before towing.
•
THE STANDARD TRANSPORT CHAIN PROVIDED IS FOR THE BASIC CART WHEN TOWED EMPTY FOR ROAD TRAVEL.
It is probable that this cart is taller, wider and longer than the towing tractor. Become aware of and
avoid all obstacles and hazards in the travel path of the equipment, such as power lines,
ditches, etc.
Always have auger folded back into storage position when auger is not in use.
To prevent damage during turning when using non-PTO equipped towing vehicles, store the
PTO driveshaft in the brackets provided on the inside right frame rail.

Auger Operation
PTO Driven Auger
•
ELECTROCUTION WILL CAUSE SERIOUS INJURY OR DEATH. THE GRAIN CART IS NOT INSULATED. KEEP AWAY FROM ALL ELECTRICAL LINES AND DEVICES. ELECTROCUTION CAN OCCUR WITHOUT
DIRECT CONTACT.
•
Entanglement with the driveline will cause serious injury or death.
Keep all guards and shields in good condition and properly installed
at all times. Avoid personal attire such as loose fitting clothing, shoe
strings, drawstrings, pants cuffs, long hair, etc. That can become entangled in a rotating driveline.
1. Before loading cart or operating auger, verify
that the flow control door is closed.
2. Choose an area free from obstructions and
unfold auger into unloading position. Allow
sufficient time for the cylinder to fully engage
the two augers.
3. Engage PTO at low RPM, then increase the
tractor PTO RPM to about 1000 rpm.
4. Open flow control door to desired unloading rate. Numbers on the auger tube provide a point of
reference for operator convenience.
NOTE: If an overload occurs, (Shear-bolt failure or excessive heat/smoke from friction clutch)
stop auger immediately. Close flow control door and relieve auger grain pressure by opening
bottom door to remove some grain from auger before resuming.
5. To slow or stop grain flow, close flow door, rather than reducing tractor RPM. Close flow door fully
when unloading is complete.
NOTE: It is not recommended to disengage auger with flow control door open. Auger system
will require substantially more torque to start, placing extra stress on both cart and tractor
driveline.
6. Stop PTO. After PTO has come to a complete stop, fold auger to the transport position.

Parker 742/842 — Operation
Optional Equipment
Hydraulic Drive
The optional hydraulically-driven auger permits
cart operation using tractors that are not
equipped with a PTO. However, due to the
power requirements of a grain cart, it should be
expected that a hydraulically-driven grain cart
will not unload as quickly as a PTO driven cart.
•
FIG. 9
Depending on the option chosen, the motor is
rated for either 55 or 100 gpm hydraulic flow
at 3000 psi. Sustained flow and pressure above
these amounts will dramatically reduce motor
life. Be aware of maximum tractor hydraulic
flow and pressure before operating auger.
NOTE: A motor containing two pressure and two
return lines is a 55 GPM motor. A motor containing
four pressure and four return lines is a 100
GPM motor. If unsure of motor size, contact
your dealer providing your cart’s serial number.

Parker 742/842 — Operation
Optional Equipment (continued)
Hydraulic Drive (continued)
NOTE: For complete assembly and operation details for the Hydraulic Drive, please refer to
the Hydraulic Drive manual (282894).
1. Before loading cart or operating auger, verify that the flow control door is closed.
2. Choose an area free from obstructions and fully unfold auger to the unloading position.
3. Connect hydraulic hoses to tractor hydraulic circuits. Attach pump pressure hoses to RETRACT
ports on tractor.
Multiple connections help utilize the tractor’s fully hydraulic power and flow. Use the tractor’s flow controls to regulate total output. See hydraulic connections for hydraulic drive in
previous “OPERATIONS” sections.
NOTE: The dual connections help utilize full tractor hydraulic power at the cart hydraulic
motor. For tractors that have more than 55 GPM available pump output, use tractor flow
controls to regulate total output to a maximum of 55 GPM.
4. Engage hydraulic drive circuits at low engine RPM one at a time, then increase engine to full throttle.
See hydraulic connections for hydraulic drive in previous “OPERATIONS” sections for cold starts.
5. While watching hydraulic pressure gauge, begin slowly opening flow control door. Stop opening
flow control door when pressure (on hydraulic gauge by pump) climbs to within 200 psi less than
maximum tractor hydraulic pressure. Ideally, maintaining maximum PTO RPM will optimize unloading performance.
•
If auger stalls during unloading, immediately place tractor hydraulic controls for motor functions in FLOAT to stop auger. Close flow control door, then move all hydraulic controls to
HOLD. Relieve auger grain pressure by opening auger cleanout door to remove some grain
before attempting to restart auger.
6. To slow or stop grain flow, close flow door rather than reducing tractor RPM. Close flow door fully
when unloading is complete.
7. Stop auger by placing both auger hydraulic circuits in FLOAT. This reduces strain on driveline components and prolongs hydraulic motor life. Move controls to HOLD after auger has come to a complete stop.
8. Choose an area free from obstructions and fully fold auger to the transport position.

When the lower & upper augers are coupled
together correctly, the leading edge of the upper
auger flighting is to be indexed approximately
180 degrees from the trailing edge of the lower
auger flighting. If these trailing/leading flighting
edges are out of position then the lower auger
drive dog must be indexed 180 degrees. Do
not remove or index the hanger bearing or
lower auger. Index only the drive dog in the
lower auger by partially removing the two 5/8”
capscrews from the drive dog shaft, turning the
drive dog 180 degrees, and reassembling the
capscrews. Partial removal of the capscrews
will retain the drive collar from dropping down

Verify Telescoping PTO Shaft Length
•
PROPERLY EXTENDED AND COLLAPSED LENGTHS OF THE TELESCOPING PTO SHAFT MUST BE VERIFIED BEFORE FIRST OPERATION WITH EACH AND EVERY DIFFERENT TRACTOR. IF THE EXTENDED LENGTH OF THE PTO SHAFT IS NOT SUFFICIENT, IT MAY BECOME UNCOUPLED IN OPERATION AND CAUSE SERIOUS INJURY OR DEATH FROM CONTACT WITH UNCONTROLLED FLAILING OF PTO SHAFT ASSEMBLY COMPONENTS.
An excessive collapsed length can result in damage to the PTO driveline and attached components.
This is most likely to occur during extreme turning angles and/or travel over rough terrain. Conditions
are amplified on tractors with tracks operating in uneven terrain, particularly rice levies.
Damaged driveline components can result in unsafe operation and severely reduced driveline
component life.
NOTE: Do not exceed 10 degrees beyond a straight pull line while operating the PTO.

4. Hitch tractor drawbar to cart, ensuring that tractor and cart are on level ground and coupled as
straight as practical.
5. Connect PTO shaft to tractor, and measure length “L” from same points as used in step 1. Ensure
that this measurement does not exceed the maximum recommended extended length calculated
in step 3 above. If necessary, choose a shorter drawbar position, or obtain a longer PTO shaft assembly before operating cart.
6. Position the tractor to obtain tightest turning
angle, relative to the cart.
7. Measure length “L” from same points as used
in step 1. This distance must be at least 1.5
inches greater than the distance measured
in step 1. If necessary, adjust length of PTO
shaft by cutting inner and outer plastic guard
tubes and inner and outer sliding profiles by
the same length. Round off all sharp edges
and remove burrs before greasing and reassembling shaft halves.

PTO Shaft and Clutch
Lubrication (Figs. D1 - D6)
Lubricate with quality grease before starting work and every 8 operating hours. Clean and
grease PTO drive shaft before each prolonged period of non-use. Molded nipples on the
shield near each shield bearing are intended as grease fittings and should be lubricated every
8 hours of operation! Telescoping members must have lubrication to operate successfully
regardless of whether a grease fitting is provided for that purpose! Telescoping members
without fittings should be pulled apart and grease should be added manually. Check and
grease the guard tubes in winter to prevent freezing.

Chains (Figs. G1 - G3)
NOTE: The chain is intended to prevent the shield
from rotating against non-moving parts and thereby preventing shield damage. A properly installed
chain will increase the service life of the shield.
1. Chains must be fitted so as to allow sufficient articulation of the shaft in all working
positions. Care must be taken to be sure
that chain does not become entangled with
drawbar hitch or other restrictions during
operation or transport of m
­ achine.

Wheel Nut Torque Requirements
•
Improperly torqued wheel nuts/bolts can cause a loss of implement
control and machine damage. Torque wheel nuts/bolts to values in
table. Check torque before use, after one hour of unloaded use or after first load, and each load until wheel nuts/bolts maintain torque
value. Check torque every 10 hours of use there-after. After each
wheel removal start torque process from beginning. Warranty does
not cover failures caused by improperly torqued wheel nuts/bolts.
Failure to check torque before first load may damage wheel nut/bolt seats. Once seats are damaged, it will become impossible to keep nuts/bolts
tight. Tighten nuts/bolts to applicable torque value
shown in table. Start all nuts/bolts by hand to prevent cross threading. Torque nuts/bolts in the recommended sequence as shown in Diagram 1.

Tire Pressure
The following is to be used as a general guide for tire inflation and figures can vary depending on specific brand of tire used. It is important that tires are inspected after
unit is loaded. Start with minimum pressure indicated. The tire should stand up with no
side-wall buckling or distress as tire rolls. Record the pressure needed to support the full
load and maintain this pressure to achieve proper tire life. Do not exceed maximum
recommended tire pressure. Each tire must be inflated to 35 PSI max to seat the
beads, deflated to 5-10 PSI, then reinflated to the tire’s max PSI when mounting.
