In order to reduce accidents and enhance the safe operation of mowers, Alamo Industrial, in cooperation
with other industry manufacturers has developed the AEM/FEMA Industrial and Agricultural Mower
Safety Practices video and guide book.
The video will familiarize and instruct mower-tractor operators in safe practices when using industrial
and agricultural mowing equipment. It is important that Every Mower Operator be educated in the operation of their mowing equipment and be able to recognize the potential hazards that can occur while operating a mower. This video, along with the mower operator’s manual and the warning messages on the
mower, will significantly assist in this important education.
Your Authorized Alamo Industrial Dealer may have shown this video and presented you a DVD Video
when you purchased your mower. If you or any mower operator have not seen this video, Watch the
Video, Read this Operator’s Manual, and Complete the Video Guidebook before operating your new
mower. If you do not understand any of the instructions included in the video or operator’s manual or if
you have any questions concerning safety of operation, contact your supervisor, dealer or Alamo Industrial.
If you would like a VHS video tape of the video, please email AEMVideo@alamo-group.com or Fax

General Safety Instructions and Practices
SAFETY
A careful operator is the best operator. Safety is of primary importance to the manufacturer and should be to
the owner/operator. Most accidents can be avoided by being aware of your equipment, your surroundings, and
observing certain precautions. The first section of this manual includes a list of Safety Messages that, if
followed, will help protect the operator and bystanders from injury or death. Read and understand these Safety
Messages before assembling, operating or servicing this Implement. This equipment should only be operated
by those persons who have read the manual, who are responsible and trained, and who know how to do so
responsibly.
The Safety Alert Symbol combined with a Signal Word, as seen below, is used throughout this
manual and on decals which are attached to the equipment. The Safety Alert Symbol means:
“ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!” The Symbol and Signal Word
are intended to warn the owner/operator of impending hazards and the degree of possible injury
faced when operating this equipment.
Practice all usual and customary safe working precautions and above all---remember safety is
up to YOU. Only YOU can prevent serious injury or death from unsafe practices.
Indicates an imminently hazardous situation that, if not avoided, WILL result in DEATH OR
VERY SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, COULD result in DEATH
OR SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, MAY result in MINOR
INJURY.
Identifies special instructions or procedures that, if not strictly observed, could result in
damage to, or destruction of the machine, attachments or the environment.
NOTE: Identifies points of particular interest for more efficient and convenient operation or
repair.(SG-1)

Safety Section 1-2
SAFETY
The rotating parts of this machine continue to rotate even after the PTO has been turned off.
The operator should remain in his seat for 60 seconds after the brake has been set, the
PTO disengaged, the tractor turned off, and all evidence of rotation has ceased. (S3PT-10)
“Wait a minute...Save a life!”
Never crawl under a raised Implement supported solely by the Tractor 3-Point hitch.
Release of the control lever or mechanical failure will result in the Implement falling and
possible injury or death. Always securely block up the Implement before crawling
underneath to perform repairs and service. (S3PT-19)
Never operate the Tractor or Implement until you have read and
completely understand this Manual, the Tractor Operator’s Manual, and
each of the Safety Messages found in the Manual or on the Tractor and
Implement. Learn how to stop the tractor engine suddenly in an
emergency.
Never allow inexperienced or untrained personnel to
operate the Tractor and Implement without supervision. Make sure the
operator has fully read and understood the manuals prior to operation.
(SG-4)
The operator and all support personnel should wear hard hats, safety
shoes, safety glasses, and proper hearing protection at all times for
protection from injury including injury from items that may be thrown by
the equipment. (SG-16)
PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE
PERMANENT HEARING LOSS! Tractors with or without an Implement
attached can often be noisy enough to cause permanent hearing loss.
We recommend that you always wear hearing protection if the noise in
the Operator’s position exceeds 80db. Noise over 85db over an
extended period of time will cause severe hearing loss. Noise over 90db
adjacent to the Operator over an extended period of time will cause
permanent or total hearing loss. NOTE: Hearing loss from loud noise
[from tractors, chain saws, radios, and other such sources close to the
ear] is cumulative over a lifetime without hope of natural recovery. (SG-I7)
INTERSTATER 03/09

Safety Section 1-3
SAFETY
Do not put hands or feet under mower decks. Blade Contact can result
in serious injury or even death.
Stay away until all motion has
stopped and the decks are securely blocked up. (SFL-2)
SAFETY
Always read carefully and comply fully with the manufacturer’s
instructions when handling oil, solvents, cleansers, and any other
chemical agent. (SG-22)
SAFETY
KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement
and possible serious injury or death. (SG-24)
Never allow children to play on or around Tractor or Implement. Children can slip or fall off
the Equipment and be injured or killed. Children can cause the Implement to shift or fall
crushing themselves or others. (SG-25)
NEVER use drugs or alcohol immediately before or while operating the
Tractor and Implement.
Drugs and alcohol will affect an operator’s
alertness and coordination and therefore affect the operator’s ability to
operate the equipment safely.
Before operating the Tractor or
Implement, an operator on prescription or over-the-counter medication
must consult a medical professional regarding any side effects of the
medication that would hinder their ability to operate the Equipment safely.
NEVER knowingly allow anyone to operate this equipment when their
alertness or coordination is impaired. Serious injury or death to the
operator or others could result if the operator is under the influence of
drugs or alcohol. (SG-27)
Prolonged operation may cause operator boredom and fatigue affecting safe operation.
Take scheduled work breaks to help prevent these potentially impaired operating
conditions. Never operate the Implement and Tractor in a fatigued or bored mental state
which impairs proper and safe operation. (SG-32)
Use extreme caution when getting onto the Implement to perform repairs, maintenance and
when removing accumulated material. Only stand on solid flat surfaces to ensure good
footing. Use a ladder or raised stand to access high spots which cannot be reached from
ground level. Slipping and falling can cause serious injury or death. (SG-33)
Avoid contact with hot surfaces including hydraulic oil tanks, pumps, motors, valves and
hose connections. Relieve hydraulic pressure before performing maintenance or repairs.
Use gloves and eye protection when servicing hot components. Contact with a hot surface
or fluid can cause serious injury from burns or scalding. (SG-34)
DO NOT operate this Implement on a Tractor that is not properly maintained. Should a
mechanical or Tractor control failure occur while operating, immediately shut down the
Tractor and perform repairs before resuming operation. Serious injury and possible death
could occur from not maintaining this Implement and Tractor in good operating condition.
(SG-36)

Safety Section 1-4
SAFETY
Equipment Operation Safety Instructions and Practices
Never leave the Tractor and Implement unattended while the Implement is in the lifted
position. Accidental operation of lifting lever or a hydraulic failure may cause sudden drop
of unit with injury or death by crushing. To properly park the implement when disconnecting
it from the tractor, lower the stand and put the retaining pin securely in place, or put a secure
support under the A-Frame. Lower the implement carefully to the ground. Do not put hands
or feet under lifted components. (S3PT-1)
This Implement is wider than the Tractor. Be careful when operating or transporting this
equipment to prevent the Implement from running into or striking sign posts, guard rails,
concrete abutments or other solid objects. Such an impact could cause the Implement and
Tractor to pivot violently resulting in loss of steering control, serious injury, or even death.
Never allow the Implement to contact obstacles. (S3PT-12)
There are obvious and hidden potential hazards in the operation of this Mower.
REMEMBER! This machine is often operated in grass and in heavy weeds. The Blades of
this Mower can throw objects if shields are not properly installed and maintained. Serious
injury or even death may occur unless care is taken to insure the safety of the operator,
bystanders, or passersby in the area. Do not operate this machine with anyone in the
immediate area. Stop mowing if anyone is within 100 yards of mower. (SFL-1)
Do not operate Mower if excessive vibration exists.
Shut down PTO and the Tractor
engine. Inspect the Mower to determine the source of the vibration. If Mower blades are
missing or damaged replace them immediately.
Do not operate the mower until the
blades have been replaced and the Mower operates smoothly. Operating the Mower with
excessive vibration can result in component failure and broken objects to be thrown
outward at very high velocities. To reduce the possibility of property damage, serious injury,
or even death, never allow the Mower to be operated with blades missing. (SFL-4)

Safety Section 1-5
SAFETY
Use extreme care when lowering or unfolding the implement’s wings. Make sure no
bystanders are close by or underneath the wings. Allow ample clearance around the
implement when folding or unfolding the wings. Use extreme caution around buildings or
overhead power lines. (S3PT-05)
SAFETY
Flail Mowers are capable under adverse conditions of throwingobjects
for great distances (100 yards or more) and causing seriousinjury or
death. Follow safety messages carefully.
STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good,
workablecondition;
SAFETY
-Mower sections
or Wings are running close to and parallel to the ground
withoutexposed Blades;
-Passerby are outside the existing thrown-object zone;-All areas have been thoroughly
inspected and all foreign material such as rocks, cans, glass, and general debris has
been removed.
NOTE: Where there are grass and weeds high enough to hide debris that could
bestruck by the blades, the area should be: inspected and large debris removed, mowed
atan intermediate height, inspected, closely with any remaining debris being removed,
andmowed again at desired final height. (This will also reduce power required to
mow,reduce wear and tear on the Mower drivetrain, spread cut material better,
eliminatestreaking, and make the final cut more uniform.) (SFL-6)
Operate this Equipment only with a Tractor equipped with an approved rollover-protective system (ROPS). Always wear seat belts. Serious injury or
even death could result from falling off the tractor--particularly during a turnover
when the operator could be pinned under the ROPS. (SG-7)
BEFORE leaving the tractor seat, always engage the brake and/or set
the tractor transmission in parking gear, disengage the PTO, stop the
engine, remove the key, and wait for all moving parts to stop. Place the
tractor shift lever into a low range or parking gear to prevent the tractor
from rolling. Never dismount a Tractor that is moving or while the engine
is running. Operate the Tractor controls from the tractor seat only. (SG-9)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
Never allow children to operate, ride on, or come close to the Tractor or
Implement. Usually, 16-17 year-old children who are mature and
responsible can operate the implement with adult supervision, if they
have read and understand the Operator’s Manuals, been trained in
proper operation of the tractor and Implement, and are physically large
enough to reach and operate the controls easily. (SG-11)
INTERSTATER 03/09

Safety Section 1-6
SAFETY
Do not mount or dismount the Tractor while the tractor is moving. Mount
the Tractor only when the Tractor and all moving parts are completely
stopped. (SG-12)
Start tractor only when properly seated in the Tractor seat. Starting a
tractor in gear can result in injury or death. Read the Tractor operators
manual for proper starting instructions. (SG-13)
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health. (SG-23)
Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause
Implement driveline or blade failures resulting in serious injury or death. (SG-26)
Operate the Tractor and/or Implement controls only while properly seated in the Tractor seat
with the seat belt securely fastened around you. Inadvertent movement of the Tractor or
Implement may cause serious injury or death. (SG-29)
In case of mechanical difficulty during operation, place the transmission in the park
position, set the parking brake, shut down all power, including the PTO and the engine and
remove the key. Wait until all rotating motion has stopped before dismounting. (SG-39)
INTERSTATER 03/09

Safety Section 1-7
SAFETY
Do not operate this Equipment with hydraulic oil or fuel leaking. Oil
and fuel are explosive and their presence could present a hazard. Do
not check for leaks with your hand! High-pressure oil streams from
breaks in the line could penetrate the skin and cause tissue damage
including gangrene. To check for a hose leak, SHUT the unit ENGINE
OFF and remove all hydraulic pressure. Wear oil impenetrable gloves,
safety glasses and use Cardboard to check for evidence of oil leaks. If
you suspect a leak, REMOVE the HOSE and have it tested at a Dealer.
If oil does penetrate the skin, have the injury treated immediately by a
physician knowledgeable and skilled in this procedure. (SG-15)
SAFETY
SAFETY
Do Not operate this equipment in areas where insects such as bees may attack you and/or
cause you to lose control of the equipment. If you must enter in such areas, use a tractor
with an enclosed Cab and close the windows to prevent insects from entering. If a tractor
cab is not available, wear suitable clothing including head, face, and hand protection to
shield you from the insects. Attacking insects can cause you to lose control of the tractor,
which can result in serious injury or death to you or bystanders. Never dismount a moving
tractor. (SG-40)
Mow only in conditions where you have clear visibility in daylight or with adequate artificial
lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least
100 yards(90 m) in front and to the sides of the tractor and mower. Make sure that you can
clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions,
power lines, debris and foreign objects. If you are unable to clearly see these type of items
discontinue mowing. (SGM-1)
The rotating parts of this machine have been designed and tested for rugged use.
However, the blades could fail upon impact with heavy, solid objects such as metal guard
rails and concrete structures. Such impact could cause the broken objects to be thrown
outward at very high velocities. To reduce the possibility of property damage, serious
injury, or even death, never allow the cutting blades to contact such obstacles. (SGM-4)
Extreme care should be taken when operating near loose objects such
as gravel, rocks, wire, and other debris. Inspect the area before
mowing. Foreign objects should be removed from the site to prevent
machine damage and/or bodily injury or even death. Any objects that
cannot be removed must be clearly marked and carefully avoided by the
operator. Stop mowing immediately if blades strike a foreign object.
Repair all damage and make certain rotor or blade carrier is balanced
before resuming mowing. (SGM-05)
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the
operating parts of the mower head. These items could then swing outside the housing at
greater velocities than the blades. Such a situation is extremely hazardous and could result
in serious injury or even death. Inspect the cutting area for such objects before mowing.
Remove any like object from the site. Never allow the cutting blades to contact such items.
(SGM-06)
Mow at the speed that you can safely operate and control the tractor and mower. The
correct mowing speed depends on terrain condition and grass type, density, and height of
cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds
when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power
lines, or when debris and foreign objects are to be avoided. (SGM-07)
INTERSTATER 03/09

Safety Section 1-8
SAFETY
Avoid mowing in reverse direction when possible. Check to make sure there are no
persons behind the mower and use extreme care when mowing in reverse. Mow only at a
slow ground speed where you can safely operate and control the tractor and mower.
Never mow an area that you have not inspected and removed debris or foreign material.
(SGM-08)
Do not mow with two machines in the same area except with Cab tractors with the windows
closed. (SGM-11)
-Equip the Tractor with a fire extinguisher in an accesible location.
-Do Not operate the Mower on a Tractor with an underframe exhaust.
-Do Not smoke or have an open flame near the Mower and Tractor.
-Do Not drive into burning debris or freshly burnt areas.
-Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating.
-Never allow clippings or debris to collect near drivelines, slip clutches, and gearboxes.
Periodically shut down the Tractor and Mower and clean clippings and collected debris from
the mower deck. (SGM-12)
The Mower is designed for certain mowing applications and is rated to cut up to a specific
size vegetation (see Mower Standard Equipment and Specifications). DO NOT use this
mower to cut vegetation above the Mower’s rated capacity or to cut any type of nonvegetative material. Only operate this Mower on a properly sized and equipped Tractor.
Operating this Mower in an application for which it is not designed and/or operating the
Mower with the wrong size Tractor can cause Mower component damage and equipment
failure resulting in possible serious injury or death. (SGM-14)
Do Not attempt to raise or lower the implement wing unless the Implement tongue is
securely attached to the Tractor drawbar. The Implement could tip over and cause
equipment damage and possible serious injury or death. Raise or Lower the mower wing
only while seated in the Tractor operator’s seat with the seat belt securely fastened. (SRM-2)
Do not let the Blades turn when the Mower Deck is raised for any
reason, including clearance or for turning. Raising the Mower deck
exposes the Cutting Blades which creates a potentially serious hazard
and could cause serious injury or even death from objects thrown from
the Blades. (SRM-07)
INTERSTATER 03/09

Safety Section 1-9
SAFETY
Follow these guidelines to reduce the risk of equipment and grass fires
while operating, servicing, and repairing the Mower and Tractor:
SAFETY
DO NOT allow any person under a folded wing unless wing is securely
locked up or supported. DO NOT approach the Implement unless the
Tractor is turned off and all motion has ceased. Never work under the
frame work, or any lifted component unless the implement is securely
supported or blocked up. A sudden or inadvertent fall by any of these
components could cause serious injury or even death. (STI-03)
SAFETY
Connecting or Disconnecting Implement Safety Instructions and Practices
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
PTO. Use of an adapter can double the operating speed of the Implement resulting in
excessive vibration, thrown objects, and blade and implement failure. Adapter use will also
change the working length of the driveline exposing unshielded driveline areas. Serious
bodily injury and/or equipment failure can result from using a PTO adapter. Consult an
authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.
(S3PT-14)
Always shut the Tractor completely down, place the transmission in park, and set the
parking brake before you or anyone else attempts to connect or disconnect the Implement
and Tractor hitches. (S3PT-15)
Never operate the Tractor and Mower if the Implement input driveline is directly connected
to the Tractor transmission. Tractor braking distances can be substantially increased by
the momentum of the rotating Mower blades driving the Tractor transmission even though
the Tractor clutch has been disengaged. Install an over running clutch between the Tractor
PTO and the Mower driveline to prevent this potentially dangerous situation. (S3PT-16)
When attaching the Implement input driveline to the Tractor PTO, it is important that the
connecting yoke spring activated locking collar slides freely and the locking balls are seated
securely in the groove on the Tractor PTO shaft. Push and pull the driveline back and forth
several times to ensure it is securely attached. A driveline not attached correctly to the
Tractor PTO shaft could come loose and result in personal injury and damage to the
Implement. (S3PT-17)
Before operating the Implement, check to make sure the Implement input driveline will not
bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates
the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out
can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and
through the support bearings or downward onto the PTO shaft, breaking it off. A broken
driveline can cause personal injury. (S3PT-18)
Each Rear Wheel must have a minimum of 1,000 pounds contact with the
surface to prevent lateral instability and possible tip-over which could
result in serious bodily injury or even death. Widen the wheel tread and
add weights if needed. Refer to the mounting instructions or call customer
service if you need assistance with counterweight procedure. (SFL-3)

SAFETY
On a fully-assembled unit, do not remove the Wing Retaining Strap until hoses are attached
to the tractor and the Wing Cylinders are filled with oil. Lower the Wings slowly and
carefully. Keep bystanders away during operations. (STI-05)
Transporting Safety Instructions and Practices
(S3PT-02)
Allow sufficient clearance for the Implement to swing outward while turning. Implements
carried behind the Tractor will swing outside the tire path when making turns. Contacting a
solid object while turning will cause equipment damage and possible injury. (S3PT-20)
Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in
such a way as to be clearly visible and legible. When transporting the
Equipment use the Tractor flashing warning lights and follow all local
traffic regulations. (SG-6)

Safety Section 1-11
SAFETY
Be particularly careful when transporting the Implement with the Tractor. Turn curves or go
up hills only at a low speed and using a gradual steering angle. Rear mounted implements
move the center of gravity to the rear and remove weight from the front wheels. Make
certain, by adding front ballast, that at least 20% of the tractor’s weight is on the front wheels
to prevent rearing up, loss of steering control or Tractor tip-over. Slow down on rough or
uneven surfaces to prevent loss of steering control which could result in property damage
or possible injury. Do not transport unless 3-Point lift lever is fully raised and in the latched
transport position. Dropping implement in transport can cause serious damage to the
tractor and/or Implement and possibly cause the operator or others to be injured or killed.
SAFETY
Transport only at speeds where you can maintain control of the
equipment. Serious accidents and injuries can result from operating this
equipment at high speeds. Understand the Tractor and Implement and how it handles
before transporting on streets and highways. Make sure the Tractor steering and brakes
are in good condition and operate properly.
SAFETY
Before transporting the Tractor and Implement, determine the proper transport speeds for
you and the equipment. Make sure you abide by the following rules:
Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes smoothly
to determine the stopping characteristics of the Tractor and Implement. As you increase
the speed of the Tractor the stopping distance increases.
Determine the maximum
transport speed not to exceed 20 mph (30 kph) for transporting this equipment.
Test the equipment at a slow speed in turns. Increase the speed through the turn only after
you determine that the equipment can be operated at a higher speed. Use extreme care
and reduce your speed when turning sharply to prevent the tractor and implement from
turning over. Determine the maximum turning speed for you and this equipment before
operating on roads or uneven ground.
Only transport the Tractor and Implement at the speeds which allow you to properly control
the equipment.
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes
or worn tires. When operating down a hill or on wet or rain slick roads, the braking distance
increases: use extreme care and reduce your speed. When operating in traffic always use
the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you
and watch out for the other guy. (SG-19)
When the Wings are folded for transport, the center of gravity is raised and the possibility of
overturn is increased. Drive slowly and use extreme caution when turning on hillsides.
Overturning the Implement could cause the Implement to overturn the Tractor and vice
versa resulting in serious injury or even death. Never fold wings on a hillside...the
Implement may overturn. (STI-02)
Only tow the Implement behind a properly sized and equipped Tractor
which exceeds the weight of the Implement by at least 20%. DO NOT
tow the Implement behind a truck or other type of vehicle. Never tow the
Implement and another Implement connected in tandem. Never tow the
Implement at speeds over 20 MPH. (STI-06)
Secure the Implement for transport before traveling on public roads. For pull-type
Implements, secure the center axle using cylinder stops or transport pin and properly attach
a safety chain between the Implement and Tractor. Secure wings in upright position on
folding Implements using wing transport locks. (STI-7)

ASSEMBLY
GENERAL INSTRUCTIONS
To assemble your new INTERSTATER and mount it to your tractor we assist you with drawings, instructions
and information, also about experiences of others and when needed just get some information or clarification
from our engineering department over the phone.
These instructions are general information and not specifically for your tractor, but in connection with our
drawings, they might offer your some valuable assistance.
ASSEMBLY
This section covers the installation procedure of an Alamo Group Interstater mower kit, and includes parts lists
for framework, hoses, and miscellaneous parts to be attached to your tractor.
These instructions are for mounting the center mower, right side mower, and left side mower units. For
mounting one mower side only, disregard information concerning the opposite side. Hardware quantities
shown are for both sides.
1. The hydraulic system must be kept “SURGICALLY CLEAN” to ensure proper operation and long life of the
pumps, motors, and valves. All components have protective caps over openings connected to internal
spaces to prevent contamination. It is important that care be taken during unpacking, assembly, and other
contaminants which will damage parts.
2. After the drive belts are installed, DO NOT start the tractor unless the hydraulic system is filled with
hydraulic oil. Running without oil will damage the pumps.
3. Check the oil level in the reservoir before start-up.
4. Care should be taken when filling the reservoir to prevent contamination of the hydraulic system. Always
use new hydraulic fluid when filling the system. USE ONLY TRACTOR HYDRAULIC OIL
IN THE
HYDRAULIC SYSTEM.Reference to the left or right side of the Interstater is determined while facing the
front of the tractor from the drivers seat.
Reference to the left or right side of the Interstater is determined while facing the front of the tractor from the
drivers seat.
Assemble the Interstater, step by step, as illustrated on the pages of this section. Small parts (bolts, nuts, etc.)
required are packed in numbered plastic bags which correspond to assembly procedures and illustrations in
the manual.
The part quantities listed for an illustration pertain only to that phase of assembly. The quantity given
corresponds to the number of parts needed. When assembling a single-sided model based on a dual-sided
model, the quantity furnished will usually be half the quantity listed.
Large parts are not always listed next to an illustration because they are usually easy to identify.
Whenever reference is made to parts, listed for an illustration or elsewhere in this manual, the following
abbreviations are used:
HHCS - hex head capscrew
RH - right hand
NF - national fine
LW - lock washer
LH - left
MA - mechanical assembly
PW- plain washer
NC - national coarse
WA - welded assembly
When installing fasteners, PW and LW (generally installed in that order) are usually on the side of the fixture or
part being fastened that the hex/lock nut is on. When only HHCS, LW and/or PW are required, they are
generally installed in that order. Some parts do not require a PW or LW. Refer to illustrations for exceptions.
Fasteners should be installed so they cause the least interference with other parts. When securing driveshaft
pulley to hub, tighten fasteners to 9 lb-ft torque.
This manual makes reference to individual component parts, some of which may have been pre assembled at
the factory.

ASSEMBLY
PRELIMINARY TRACTOR PREPARATION
Depending on the make and model of tractor the INTERSTATER is to be mounted on, certain modifications will
be illustrated. In some cases special accessory components for the tractor will be required before assembling
the INTERSTATER. In these cases, specific mention will be made to the manufacturer, part number and

HYDRAULICS
ASSEMBLY
Refer the Tractor Manual when connecting hydraulic hoses to the tractor hydraulic system.
Not only does the installation procedure vary from tractor to tractor, but numerous
precautions should be taken due to the possibility of a pressure buildup within the hydraulic
circuit. Relieve the pressure before opening or entering the circuit. FLUID ESCAPING
UNDER PRESSURE CAN PENETRATE THE SKIN CAUSING SERIOUS INJURY. Ensure
that hose fittings are secure before pressurizing the hydraulic systems.
Once pumps and belts are installed, DO NOT start the tractor (which will turn pumps) unless
both power circuits are filled with the specified hydraulic fluid. Running pumps without oil will
cause non-warrantable damage.
It is important that pipe thread sealant be used only on solid connections of pipe thread;
never on connections between swivel fittings and solid male pipe threads or on straight thread "O" ring fittings.
Use the pipe thread sealant supplied. Do not substitute with some other type of sealant, i.e., teflon tape, paint,
shellac, etc.
Hoses supplied have two types of fittings; solid or swivel. Some hoses have solid fittings on both ends; others
have a solid fitting and a swivel fitting. Hoses with two solid fittings will fit into either a female solid thread, or a
swivel adapter union. When installing either type hose, solid fittings must be installed first, then install the
swivel end of the hose.
The INTERSTATER hydraulic system incorporates three basic types of hydraulic fittings:
a. Standard pipe (NPT or NPTF) thread fittings. This type requires a small amount of evenly-applied sealant.
b. Swivel fittings. This type does not require any sealant on the swivel end because it seals against an internal
flare.
c. “O” Ring fittings. This type does not require any sealant on the “O” Ring end of the fitting.
It is extremely important to avoid getting pipe thread sealant inside the fittings or hoses. KEEP THE INTERIOR
OF ALL HYDRAULIC COMPONENTS SURGICALLY CLEAN. Inspect the inside diameter of each hose before
assembly. Ensure that no obstruction is present. Dirt, sand, dust, etc., are abrasive and once in the system can
cause immediate or early failure.
POWER CIRCUIT
Using the following drawing and your installation drawing as a guide to install the hydraulic hoses and fittings
for the power circuit. The power circuit drives the Interstater wing cutter units. The control circuit (for lift and tilt)
will be assembled later.
NOTE: Do not strap hoses together until all hoses and wiring are connected. Hoses and wiring should be
routed so they do not lay on moving parts, too close to sharp edges, or near excessive heat.

ASSEMBLY
INITIAL START-UP PROCEDURE
1. Check all nuts and hex head capscrews to ensure all are tight and all lock washers are fully compressed
(flattened).
2. Check all hoses and hydraulic connections. Make certain they are secure.
3. Inspect all moving parts and be sure that no wires or hoses will be caught or pinched when the tractor or
the INTERSTATER is in operation. Tie down loose wires and hoses.
ASSEMBLY
4. Thoroughly grease the INTERSTATER and install a lubricap on each grease fitting. Refer to the Operation
and Maintenance Section.
5. Jack front of tractor up enough to allow axle to pivot through its full range. While turning wheels through
their limits, right and left, swing them up and down. Look for interference between tires and any part of the
INTERSTATER. If interference occurs, shims (not furnished) must be welded to axle pivot stop or steering
arm to limit the movement enough to avoid interference. Tractors with an adjustable front axle may require
an outward adjustment of the wheels.
6. To fill the INTERSTATER reservoir with new, clean hydraulic oil, follow the steps below. Refer to the
Operation and Maintenance Section for specifications.
a. With a hydraulic jack raise the right side of the tractor. This will tilt the tank and allow only a minimum amount
of air when filling.
b. Avoid hydraulic contamination by filtering the hydraulic oil while filling the hydraulic tank. ASM-FL-0038

Filter buggies or carts are commercially
available for hydraulic system clean-up.
These consist of a high-efficiency, highcapacity filter, a circulating pump, a drive
motor, and hoses for connecting the
overhauled machine’s hydraulic system.
ASM-FL-0048
7. After the Interstater mower is completely
assembled to the tractor and with the wings
on the ground, fill the mower hydraulic tank
above the oil level sight gauge approximately 5" or 1" below the top of the tank.
8. With mower ON/OFF switches in “ON” position and tractor fuel cut off, crank engine for about 30 to 45
seconds to allow oil to fill pumps and motors. Check the oil level in the sight gauge. If no oil is seen add oil to
bring the level up to the sight gauge. NOTE: Do not fill the tank with oil above the level of the sight gauge.
Over filling the tank with oil after the initial filling may result in oil being discharged through the air filter on top of
the hydraulic tank. Start the tractor and run it for 2 minutes and then turn it off. Again check the oil level in the
sight gauge. If the oil level is in the sight gauge, the unit is ready to run. If no oil is seen, add oil to bring the
level up to the sight gauge.
Remove all foreign objects and stand clear of cutter units. DO NOT GET NEAR ROTATING
KNIVES!
NOTE: On tractor hydraulic powered circuit only, make certain that there is full flow from tractor hydraulic
system to control valve. Refer to tractor manual.
9. After hydraulic system is fully charged and functioning properly, switch cutter units on, then speed engine up
to 540 RPM PTO speed. Maintain this speed for about 5 minutes. Check complete INTERSTATER, look for
any leaks, loose connections, or anything that could cause premature wear or failure.
FINAL CHECK
Run INTERSTATER for about 1/2 hour at full speed. Check for leaks and vibrations. Frequently check oil
temperature. Make certain it does not exceed 180 deg.
NOTE: When raising wings, make certain there is no interference with mower, frame, cylinders or tractor. Lift
wings slowly.
DO NOT leave unit unattended, and COMPLY WITH ALL WARNING DECALS.
If unit starts to make unusual noise, stop unit and check oil level. Also check for frothy oil which would indicate
a leak on suction side of system.

ASSEMBLY
INSTALLATION OF REAR MOWER
Before attaching mower to tractor, it will be necessary that each tractor lower hitch arm has freedom of
movement so that the mover is completely independent of tractor movement. This will allow the mower to pivot
sideways as well as move vertically.
ASSEMBLY
Some tractors provide this “float” by means of an optional slot in the lower end of each lift link, others by lift
links which can be made telescopic by changing the position of the pins in the links. Failure to provide “float”
may result in failure of the cutterhousing and bearings in the roller, thus voiding the mover warranty. Should
your tractor not have a built in “float” option, a flexible lift chain assembly will be required.
On all centered mowers, two flexible lift chain assemblies will be necessary to provide “float” to each lift link.
On all offset mowers, one flexible lift chain assembly will be necessary to provide “float” to the lift link on the
same side that the mover is offset. The other lift link should be the adjustable stiff link furnished with the
tractor.
After the mower is attached to the tractor’s 3-point hitch, but before the universal slip joint is installed, and with
the mover on the ground, adjust the top link of the hitch to make the mower gearbox input shaft parallel to the
tractor P.T.O. shaft. This relationship provides optimum operation of the universal joints in the driveline.
Driveline that is not parallel to PTO will result in vibration due to the characteristic of a universal joint that
results in the output end speeding up and slowing down twice each revolution of the universal jointed shaft.
Adjust the top link whenever the cutting height is changed.
1. Tip cutterhousing back and place a block under roller to safely support unit. Remove shipping skids and
drive pulley side belt guard fender. If necessary, install knives, as shown, one row at a time. ALL KNIFE PINS
ARE INSTALLED WITH THEIR HEADS FACING AWAY FROM THE CUTTERSHAFT PULLEY. This will
locate cotter pins where knives cannot reach them when flexing backward. The housing side sheet has a hole
in it which allows knife pins to be inserted into end lugs from outside the cutterhousing. After the cotter pin is
installed, bend extended prong at a 45 Degree angle with prong parallel to lug. ASMP-FL-0047

If extension shaft does not line-up with Gearbox, it may be necessary to shim gearbox
mounting lugs. To accomplish this, insert one gearbox retaining bolt (Item 1), ASM-FL0050 thru the mount plate and into the gearbox housing. Do not tighten this bolt (it should
have at least 1/4" free threads to move in and out). Assemble the gearbox, shaft, shaft
extension tube and the bearing to the bearing retainer plate mounted on the side sheet.
Tighten all fasteners except the one bolt in the gearbox mounting plate. Check the
distance between the gearbox mounting lugs and the mount plate. If required, insert shims
from shim kit (P/N 000552), ASM-FL-0051 between gearbox mounting lugs and mounting
plate to insure the gearbox pulls up evenly on the mounting plate.

ALAMO INDUSTRIAL INTERSTATER
OPERATING INSTRUCTIONS
OPERATION
Alamo Industrial Interstater flail mowers are manufactured with quality material by skilled workers. These
mowers are designed for cutting grass and small weeds. The mower is equipped with protective deflectors to
prevent objects being thrown from the mower by the blades, however, no shielding is 100% effective. All
shields, guards, and deflectors equipped on the mower must be maintained in good operational condition.
It is the operator’s responsibility to be knowledgeable of all potential operating hazards and to take every
reasonable precaution to ensure oneself, others, animals, and property are not injured or damaged by the
mower, tractor, or a thrown object. Do not operate the mower if passersby, pets, livestock, or property are
within 100 yards of the unit.
This section of the Operator’s Manual is designed to familiarize, instruct, and educate safe and proper mower
use to the operator. Pictures contained in this section are intended to be used as a visual aid to assist in
explaining the operation of a Interstater flail mower and are not specific to any model. Some pictures may show
shields removed for picture clarity. NEVER operate implement without all shields in place and in good
operational condition. The operator must be familiar with the mower and tractor and all associated safety
practices before operating the mower and tractor. Proper operation of the mower, as detailed in this manual,
will help ensure years of safe and satisfactory use of the mower.
To avoid mower damage, retorque all bolts after the first 10 hours of operation. Refer to the
Torque Chart at the end of the Maintenance Section to ensure bolts are properly tightened.

3. TRACTOR REQUIREMENTS
In addition to tractor horsepower and size required to operate the boom unit, the tractor must also be properly
equipped to provide operator protection, to alert approaching vehicle drivers of the tractor’s presence, and to
ensure tractor stability when mowing with the boom fully extended.
Tractor Requirements and Capabilities
•
•
ASAE approved Roll-Over Protective Structure (ROPS) or ROPS cab and seat belt.
Tractor Safety Devices ..................... Slow Moving Vehicle (SMV) emblem, lighting, PTO master shield
Tractor Horsepower-Minimum .......... Rear INT 88” 60hp, Rear INT 96” 60hp
Drawbar............................................ 14” length-measured from end of PTO shaft to hitch pin hole, rated to
carry mower tongue weight, safety chain attachment point
Hydraulics......................................... 4-Spool Valve & 2-Spool Valve with Detent Position
Power Take Off................................. 540 RPM
3.1 ROPS and Seat Belt
The tractor must be equipped with a Roll-Over-Protective-Structure (ROPS) (tractor cab or roll-bar) and seat
belt to protect the operator from falling off the tractor, especially during a roll over where the driver could be
crushed and killed. Only operate the tractor with the ROPS in the raised position and seat belt fastened.
Tractor model not equipped with a ROPS and seat belt should have these life saving features installed by an
authorized dealer. OPS-U- 0003
Operate this Equipment only with a Tractor equipped with an approved rollover-protective system (ROPS). Always wear seat belts. Serious injury or
even death could result from falling off the tractor--particularly during a turnover
when the operator could be pinned under the ROPS. (SG-7)
3.2 Tractor Safety Devices
If transporting or operating the tractor and implement near a public roadway, the tractor must be equipped with
proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of
the unit. Lights and a SMV emblem must be equipped directly on implements if the visibility of the tractor
warning signals are obscured.
Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were
removed for access to connect, service, or repair the tractor or implement. Never operate the tractor PTO
with the PTO master shield missing or in the raised position. OPS-U- 0004
3.3 Tractor Horsepower
The horsepower required to operate the mower depends on many factors including the vegetation to be cut,
terrain condition, operator experience, and condition of the mower and tractor. For most mowing condition, the
Rear INT 88” & 96”mowers require a tractor with at least 60HP. Operating the mower with a tractor that does
not have adequate power may damage the tractor engine.

•
•
OPERATION
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
PTO. Use of an adapter can double the operating speed of the Implement resulting in
excessive vibration, thrown objects, and blade and implement failure. Adapter use will also
change the working length of the driveline exposing unshielded driveline areas. Serious
bodily injury and/or equipment failure can result from using a PTO adapter. Consult an
authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.
OPERATION
(S3PT-14)
Never operate the Tractor and Mower if the Implement input driveline is directly connected
to the Tractor transmission. Tractor braking distances can be substantially increased by
the momentum of the rotating Mower blades driving the Tractor transmission even though
the Tractor clutch has been disengaged. Install an over running clutch between the Tractor
PTO and the Mower driveline to prevent this potentially dangerous situation. (S3PT-16)
4. GETTING ON AND OFF THE TRACTOR
Before getting onto the tractor, the operator must read and completely understand the implement and tractor
operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for
a complete explanation. OPS-U- 0007
Do not mount or dismount the Tractor while the tractor is moving. Mount
the Tractor only when the Tractor and all moving parts are completely
stopped. (SG-12)
4.1 Boarding the Tractor
Use both hands and equipped handrails and steps for support when boarding the tractor. Never use control
levers for support when mounting the tractor. Seat yourself in the operator’s seat and secure the seat belt
around you.
Never allow passengers to ride on the tractor or attached equipment. Riders can easily fall off and be
seriously injured or killed from falling off and being ran over. It is the operator’s responsibility to forbid all extra
riders at all times. OPS-U- 0008
Never allow children to operate, ride on, or come close to the Tractor or
Implement. Usually, 16-17 year-old children who are mature and
responsible can operate the implement with adult supervision, if they
have read and understand the Operator’s Manuals, been trained in
proper operation of the tractor and Implement, and are physically large
enough to reach and operate the controls easily. (SG-11)
INTERSTATER 03/09

OPERATION
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
Do not mount or dismount the Tractor while the tractor is moving. Mount
the Tractor only when the Tractor and all moving parts are completely
stopped. (SG-12)
Before dismounting the tractor, idle the tractor engine down, disengage the head and retract the boom arm to
the transport position. Park the tractor on a level surface, set the transmission in park or neutral and apply
the parking brake. Shut down the tractor engine, remove the key, and wait for all motion to come to a
complete stop before exiting the operator’s seat. NEVER leave the seat until the tractor, its engine, and
mower head movement have come to a complete stop.
Use hand rails and extra steps when exiting the tractor. Be careful of your step and use extra caution when
mud, ice, snow, and other matter has accumulated on the steps and handrails. Never rush or jump off the
tractor. OPS-B- 0002
BEFORE leaving the tractor seat, always engage the brake and/or set
the tractor transmission in parking gear, disengage the PTO, stop the
engine, remove the key, and wait for all moving parts to stop. Place the
tractor shift lever into a low range or parking gear to prevent the tractor
from rolling. Never dismount a Tractor that is moving or while the engine
is running. Operate the Tractor controls from the tractor seat only. (SG-9)

Make sure all guards, shields, and other safety devices are securely in place.
The parking brake is on.
The tractor transmission levers are in park or neutral.
The boom operating controls are in the neutral and off position.
The PTO control lever is disengaged.
The hydraulic remote control levers are in the neutral position.
Refer to the tractor owner’s manual for tractor starting procedures. Only start the tractor while seated and
belted in the tractor operator’s seat. Never bypass the ignition switch by short circuiting the starter solenoid.
After the tractor engine is running, avoid accidental contact with the tractor transmission to prevent sudden
and unexpected tractor movement. OPS-B- 0003
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health. (SG-23)
Start tractor only when properly seated in the Tractor seat. Starting a
tractor in gear can result in injury or death. Read the Tractor operators
manual for proper starting instructions. (SG-13)
6. CONNECTING THE MOWER TO THE TRACTOR
Use extreme caution when connecting the mower to the tractor. The mower should be securely resting at
ground level or setting on blocks. Keep hands and feet from under the mower deck and clear of pinch points
between the tractor hitch arms and mower pins. OPS-R-0001
INTERSTATER 03/09
© 2009 Alamo Group Inc.
Operation Section 4-8
OPERATION
Always shut the Tractor completely down, place the transmission in park, and set the
parking brake before you or anyone else attempts to connect or disconnect the Implement
and Tractor hitches. (S3PT-15)
6.1 Connecting the Mower A-Frame to the Tractor
6.2 Safety Tow Chain
If the mower is towed on a public roadway, a safety chain with tensile strength equal to or greater than the
gross weight of the mower must be connected between the tractor and mower. This will help control the
implement in the event the tongue becomes disconnected from the drawbar. Make sure the chain is attached
to a secure location on the tractor and not to an intermediate support.
After connecting both ends of the safety chain, drive the tractor to the right and left to check for proper chain
length. Adjust length as necessary and allow only enough slack in the chain to make a maximum turn in both
directions. When not in use, store the safety chain to protect it from mud or standing water by wrapping the
chain around the tongue. Replace the safety chain if one ore more links or end fittings are broken, stretched or
otherwise damaged or deformed. OPS-U-0039
INTERSTATER 03/09
© 2009 Alamo Group Inc.
Operation Section 4-9
OPERATION
1. Make sure the tractor is equipped with the
correct PTO shaft. Change shafts if needed.
2. Shorten or remove the tractor drawbar to avoid
interference when raising and lowering the
mower.
3. Board the tractor and start the engine. Position
the tractor to the mower with the 3-point lift
arms positioned between the respective set of
mower A-frame lift lugs. Note: Set the 3-point lift
control to “Position Control” so that the lift arms
maintain a constant height when attaching the
mower. See the tractor Operator’s Manual for
correct settings when attaching 3-point
equipment.
4. Turn off the tractor engine and dismount.
5. One lift arm at a time, align arm end hole
between the set of A-frame lift lugs. Insert hitch
pin through the lug and arm holes and insert
retaining pin into hitch pin.
6. Walk around to opposite side and repeat
procedure for remaining lift arm and hitch pin.
7. Extend or retract 3-point top link to align its end
hole with the holes of the mower’s top link.
Insert the top link hitch pin and insert retaining
pin into hitch pin.
8. Adjust any lower link check chains, guide
blocks, or sway blocks to prevent the mower
from swaying side to side and possible contact
with tractor rear tires.
OPERATION
7. SETTING THE MOWER
OPERATION
Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make
a more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow the contour of
uneven terrain. NOTE: Avoid very low cutting heights, striking the ground with the blades gives the most
damaging shock loads and will cause damage to the mower and drive. Blades contacting the ground may
cause objects to be thrown out from under the mower deck. Always avoid operating the mower at a height
which causes the blades to contact the ground. OPS-U- 0010
Never work under the Implement, the framework, or any lifted
component unless the Implement is securely supported or blocked up
to prevent sudden or inadvertent falling which could cause serious
injury or even death. (SG-14)

OPERATION
7.1 Roller Height Adjustment
Hydraulic Cylinder Priming
Hydraulic Cylinders must be filled with hydraulic oil before releasing the wing transport locks to lower the
mower. Hydraulic cylinders and lines are filled by holding the valve control levers in the raised position until the
cylinders fully extend then place the control lever in the float position. Repeat the process several more times
to ensure wings are entirely supported by the hydraulic cylinders before releasing the transport locks and
lowering the mower.
INTERSTATER 03/09
© 2009 Alamo Group Inc.
Operation Section 4-11
OPERATION
1. The mower’s cutting height is set by positioning
the roller assembly for each mower section.
Each section must be set at the same height to
ensure an even cut across the entire width of
the mower.
2. Place the tractor and mower on a level surface
and completely lower the mower to the ground.
3. Shut down the tractor, place the transmission in
park, and set the parking brake before
dismounting.
4. One section at a time, place lifting device
(scissors jack or hydraulic jack) under center of
cutter housing.
5. Remove hex nuts, washers and carriage bolts
from bracket at each end of roller. Make certain
that roller bracket is free to move once the
fasteners are removed. A stuck roller could
drop unexpectedly and cause injury.
6. Use lifting device to reposition cutter housing to
desired cutting height. Align bracket holes with
cutter housing, then reinstall hardware.
7. Lower cutter housing to the ground and remove
lifting device.
8. Set cutting height according to procedures
above for remaining two cutter sections. Make
sure that all three rollers are set at the same
height to ensure a even cut across the entire
width of the mower.
OPERATION
7.2 Leveling Deck
OPERATION
To Facilitate a safe and efficient mowing operation,
the mower should be operated parallel to the
ground at all times. Never operate if front or rear of
mower is tilted upward. Objects may be discharged
at high speeds causing possible injury or even
death.
Adjust Top Link to level mower roller adjustment.
Side Skid Shoes should always be parallel to
ground throughout the full adjustment range. Adjust
cutting height of machine by raising or lowering rear
roller as specified in Operation Section.
Do not let the Blades turn when the Mower Deck is raised for any
reason, including clearance or for turning. Raising the Mower deck
exposes the Cutting Blades which creates a potentially serious hazard
and could cause serious injury or even death from objects thrown from
the Blades. (SRM-07)
8. DRIVELINE ATTACHMENT
The driveline yoke and tractor PTO shaft must be
dirt free and greased for attachment.
To connect the mower driveline to the tractor
PTO output shaft, pull the driveline yoke collar
back and align the grooves and splines of the
yoke with those of the PTO shaft. Push the
driveline yoke onto the PTO shaft, release the
locking collar, and position the yoke until the
locking collar balls are seated onto the PTO
shaft. Push and pull the driveline back and forth
several times to ensure a secure attachment.
After the driveline is securely attached, place the
tractor PTO master shield back in the operating
position. OPS-R-0003
8.1 Driveline Length Check
Before operating the Implement, check to make sure the Implement input driveline will not
bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates
the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out
can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and
through the support bearings or downward onto the PTO shaft, breaking it off. A broken
driveline can cause personal injury. (S3PT-18)
INTERSTATER 03/09

Operation Section 4-12
OPERATION
When fitting the mower to the tractor, the telescoping driveline must be inspected to ensure that at its most
compressed position, the profiles do not “bottom out”, and when at its farthest extended position, there is
sufficient engagement between the profiles to operate safely. At its shortest length, there must be at least a 1”
clearance between each profile end and opposite profile universal joint. At its farthest operating extension, a
minimum profile engagement of 12” must be maintained.
“Bottoming Out” Check Procedure
•
•
•
INTERSTATER 03/09

Operation Section 4-13
OPERATION
•
Disconnect driveline from the tractor and slide
the profiles together until fully compressed.
Place a mark on the inner shield 1/8” from the
end of the outer shield and reattach the
driveline to the PTO Shaft.
With the PTO NOT TURNING, slowly drive the
tractor with mower attached through the
sharpest turn possible and watch shaft
movement. With the PTO NOT TURNING,
slowly drive the tractor with the mower attached
through the most severe terrain conditions
expected and watch shaft movement.
If the distance between the mark and the outer
shield becomes less than 2” at any point there
is a potential problem bottoming out the
driveline and the driveline should be shortened.
OPS-F-0001
OPERATION
Shorten the driveline profiles as follows:
•
•
OPERATION
•
•
•
•
•
Remove the driveline from the tractor.
Position the mower to the point with the shortest
distance between the tractor PTO shaft and cutter
gearbox. Shut down the tractor and securely block
the mower in this position.
Pull driveline apart and reattach yoke to PTO shaft.
Hold driveline sections parallel to one another and
measure back 1” from yoke of each shaft and place
mark on opposite section. Cut this length off with a
saw.
Round off all sharp edges and debur.
Thoroughly grease then reinstall the driveline.
Recheck for proper operation.
Engagement Check Procedure
•
•
•
•
•
With the driveline attached, position the mower to the
point where the telescoping driveline is at its maximum extension. Completely shut down the tractor and secure in
position.
Mark the inner driveline shield 1/8” from the end of the outer shield.
Disconnect the driveline from the tractor and separate the two driveline halves.
Measure the distance from the mark to the end of the inner profile. This length is the amount the driveline profiles
were engaged.
If the engaged length is less than 12” the shaft is considered too short and should be replaced with a longer shaft.
Consult an authorized dealer to purchase the required driveline length.
NOTE: If the driveline cannot be shortened and still maintain the required profile engagement, the operator must be made
aware of terrain conditions and avoid situations which pose a potential problem to avoid damaging the driveline.
OPS-F-0002
9. PRE-OPERATION INSPECTION AND SERVICE
Before each use, a pre-operation inspection and service of the implement and tractor must be performed.
This includes routine maintenance and scheduled lubrication, inspecting that all safety devices are equipped
and functional, and performing needed repairs. DO NOT operate the unit if the pre-operation inspection
reveals any condition affecting safe operation. Perform repairs and replacement of damaged and missing
parts as soon as noticed. By performing a thorough pre-operation inspection and service, valuable down time
and repair cost can be avoided. OPS-U-0029
Always disconnect the main PTO Driveline from the Tractor before performing service on
the Mower. Never work on the Mower with the tractor PTO driveline connected and
running. Blades or Drivelines could turn without warning and cause immediate
entanglement, injury or death. (SRM-3)

10. DRIVING THE TRACTOR AND IMPLEMENT
Safe tractor transport requires the operator possess a thorough knowledge of the model being operated and
precautions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the
weight of the implement and the tractor operating controls are set for safe transport. To ensure safety while
driving the tractor with an attached implement, review the following. OPS-U- 0012
Transport only at speeds where you can maintain control of the
equipment. Serious accidents and injuries can result from operating this
equipment at high speeds. Understand the Tractor and Implement and
how it handles before transporting on streets and highways. Make sure the Tractor steering
and brakes are in good condition and operate properly.
Before transporting the Tractor and Implement, determine the proper transport speeds for
you and the equipment. Make sure you abide by the following rules:
Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes smoothly
to determine the stopping characteristics of the Tractor and Implement. As you increase
the speed of the Tractor the stopping distance increases.
Determine the maximum
transport speed not to exceed 20 mph (30 kph) for transporting this equipment.
Test the equipment at a slow speed in turns. Increase the speed through the turn only after
you determine that the equipment can be operated at a higher speed. Use extreme care
and reduce your speed when turning sharply to prevent the tractor and implement from
turning over. Determine the maximum turning speed for you and this equipment before
operating on roads or uneven ground.
Only transport the Tractor and Implement at the speeds which allow you to properly control
the equipment.
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes
or worn tires. When operating down a hill or on wet or rain slick roads, the braking distance
increases: use extreme care and reduce your speed. When operating in traffic always use
the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you
and watch out for the other guy. (SG-19)
INTERSTATER 03/09

Operation Section 4-23
OPERATION
This Implement is wider than the Tractor. Be careful when operating or transporting this
equipment to prevent the Implement from running into or striking sign posts, guard rails,
concrete abutments or other solid objects. Such an impact could cause the Implement and
Tractor to pivot violently resulting in loss of steering control, serious injury, or even death.
Never allow the Implement to contact obstacles. (S3PT-12)
OPERATION
10.1 Starting the Tractor
OPERATION
The procedure to start the tractor is model specific.
Refer to the tractor operator’s manual for starting
procedures for your particular tractor. Consult an
authorized dealer if the starting procedure is
unclear. Ensure the 3-point control lever is in the
lowered position and the PTO is disengaged before
starting the tractor. OPS-U-0033
10.2 Brake and Differential Lock Setting
Make sure the tractor brakes are in good
operating condition. Tractor brakes can be set to
operate independently allowing single rear wheel
braking action or locked together to provide
simultaneous rear wheel braking. FOR MOST
DRIVING AND OPERATING CONDITIONS, THE
BRAKE PEDALS SHOULD BE LOCKED
TOGETHER TO PROVIDE THE MOST
EFFECTIVE BRAKING ACTION.
Always disengage the tractor differential lock
when turning. When engaged the differential lock
will prevent or limit the tractor from turning. During
normal cutting conditions, locking the differential
provides no benefit and should not be used.
OPS-U- 0013
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes.
When operating down a hill or on wet or rain slick roads, the braking distance increases; use
extreme care and reduce your speed in these conditions. When operating in traffic, always
use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around
you and watch out for the other guy.

10.3 Operating the Mower Wings
Transport Position
1. With tractor engine running, place ON/OFF
switch(s) in "OFF" position and wait for
cuttershaft(s) to stop rotating.
2. Pull LIFT control lever rearward until lift frame is
as high as it will go.
4. Push LIFT control lever forward enough to lower
unit slowly. Bar on cylinder support must pass
through bracket on unit as shown in Figure 2.
5. Make certain that all control levers are in "HOLD"
position when transporting unit.
NOTE: Lift and Tilt cylinder rods may be adjusted to
provide proper transport bracket to support bar
clearance.
Loosen rod end clamp.
Shorten stroke on LIFT cylinder to raise lift frame.
Lengthen stroke on LIFT cylinder to lower lift frame.
and/or
Shorten stroke on TILT cylinder to move transport
bracket closer to support bar. Lengthen stroke on
TILT cylinder to move transport bracket away from
support bar.
Once sufficient clearance is obtained, tighten rod
end clamp.
The mower’s center of gravity is raised making the
mower more prone to tipping when the wings are in
the raised position. Use extreme caution when
towing the mower in the transport position and
avoid uneven terrain which could upset the mower.
When the Wings are folded for transport, the center of gravity is raised and the possibility of
overturn is increased. Drive slowly and use extreme caution when turning on hillsides.
Overturning the Implement could cause the Implement to overturn the Tractor and vice
versa resulting in serious injury or even death. Never fold wings on a hillside...the
Implement may overturn. (STI-02)

TILT control lever forward until cutter unit is level
with ground.Push LIFT lever forward enough to
slowly lower unit until it touches ground, then push
both levers forward to "FLOAT" position.
NOTE: For best mowing results and longer roller
life, both LIFT and TILT levers should be in
"FLOAT" position while mowing.
It takes some effort to pull TILT lever from "FLOAT"
position because of detent spring.
The mower must be operated with the cutter
sections fully lowered and the hydraulic control
lever in the float detent to ensure the mower follows
the contour of the ground and to prevent sections
from creeping up. NEVER attempt to raise the
mower while the mower is operating.

OPERATION
10.4 Driving the Tractor and Implements
Drive the tractor with the 3-Point lift arms in the
raised position and lock the control lever in the
transport detent position to prevent damage to
the mower driveline and tongue when turning.
Perform turns with the tractor and units at slow
speeds to determine how the tractor with an
attached blade or rake handles a turn. Determine
the safe speed to maintain proper control of the
tractor when making turns. When turning with a
towed implement, the overall working length of
the unit is increased. Allow additional clearance
for the units when turning.
To avoid overturns, drive the tractor with care and
at safe speeds, especially when operating over
rough ground, crossing ditches or slopes, and
turning corners. Tractor wheel tread spacing
should be increased when working on inclines or
rough ground to reduce the possibility of tipping.
Use extreme caution when operating on steep
slopes. Keep the tractor in a low gear when going
downhill. DO NOT coast or free-wheel downhill.

Operation Section 4-27
OPERATION
Start off driving at a slow speed and gradually
increase your speed while maintaining complete
control of the tractor and units. Moving slowly at
first will also prevent the tractor from rearing up
and loss of steering control. The tractor should
never be operated at speeds that cannot be
safely handled or which will prevent the operator
from stopping quickly during an emergency. If the
power steering or engine ceases operating, stop
the tractor immediately as the tractor will be
difficult to control.
OPERATION
OPERATION
10.5 Crossing Ditches and Steep Inclines
When crossing ditches with steep banks or going up
sharp inclines, it is possible that the main driveline
inner profile will penetrate into the outer housing to its
maximum depth until the assembly becomes solid
(driveline is at its extreme shortest length). This type
of abusive operation can cause serious damage to
the tractor and mower drive by pushing the PTO into
the tractor and through the support bearings or
downward onto the PTO shaft, breaking it off.
Damage resulting from over-collapse of the driveline’s inner profile and its outer housing
may allow the driveline to come loose from the Tractor which could cause bodily injury to the
operator or bystanders and/or extensive damage to the Tractor or Implement. OPS-R-0020
When contronted with an incline or ditch, do not
approach from an angle which is perpendicular or
straight on as damaged to over collapse of the
driveline may occur.
When crossing such terrain, the implement should
be fully lowered for a lower center of gravity and
added stability. OPS-R-0021
INTERSTATER 03/09
© 2009 Alamo Group Inc.
Operation Section 4-28
OPERATION
Inclines and ditches should be approached along a
line which is at an angle as shown. This type of
path will reduce the possibility of over-collapse of
the driveline and resulting damage. If the gradient
is so steep that such an approach increases the
possibility of a tractor roll-over, select an alternate
crossing path.
11. OPERATING THE TRACTOR AND IMPLEMENT
THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND
IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE. The operator must read and
understand the Safety and Operation Sections of the implement and tractor operator’s manuals. These
manuals must be read and explained to any operator who cannot read. Never allow someone to operate the
implement and tractor without complete operating instructions.
Before starting any operation, the operator must become familiar with the area to be worked in and any
obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special
attention should be paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area.
OPS-U- 0015
Extreme care should be taken when operating near loose objects such
as gravel, rocks, wire, and other debris. Inspect the area before
mowing. Foreign objects should be removed from the site to prevent
machine damage and/or bodily injury or even death. Any objects that
cannot be removed must be clearly marked and carefully avoided by the
operator. Stop mowing immediately if blades strike a foreign object.
Repair all damage and make certain rotor or blade carrier is balanced
before resuming mowing. (SGM-05)
INTERSTATER 03/09
© 2009 Alamo Group Inc.
Operation Section 4-29
OPERATION
When operating the tractor and mower across
slopes and inclines, through ditches, and other
uneven terrain conditions, it is important to maintain
sufficient deck to ground clearance. Blade contact
with the ground may cause soil, rocks and other
debris to be thrown out from under the mower
resulting in possible injury and/or property damage.
Ground contact also produces a severe shock load
on the mower drive and to the mower blades
resulting in possible damage and premature wear.
OPS-R-0022
OPERATION
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the
operating parts of the mower head. These items could then swing outside the housing at
greater velocities than the blades. Such a situation is extremely hazardous and could result
in serious injury or even death. Inspect the cutting area for such objects before mowing.
Remove any like object from the site. Never allow the cutting blades to contact such items.
(SGM-06)
OPERATION
11.1 Foreign Debris Hazards
Before mowing, inspect the area to make sure
there are no foreign objects that the mower blades
could hit or become entangled with. Remove all
foreign objects and debris. If objects are too big to
remove, mark them clearly and be sure to prevent
the mower blades from contacting them.
If you hit a solid object or foreign debris, stop the
mower and tractor at once. Immediately idle the
engine speed and disengage the PTO. Wait for all
mower rotating motion to stop, then raise the
mower and move the tractor and implement off the
object. Inspect the area and remove, or mark the
location of the debris. Inspect the condition of the
mower and make any needed repairs immediately.
Make sure the blades are not damaged and the
carrier is balanced before resuming operation.
Always wear your seat belt securely fastened and
only operate the tractor and mower with the ROPS
in the raised position. If the tractor or mower hits a
tree stump, rock, or bump, a sudden movement
could throw you off of the seat and under the
tractor and/or mower. The seat belt is your best
protection from falling off the tractor and the ROPS
provides protection from being crushed during a
tractor roll-over. OPS-F-0010
11.2 Bystanders/Passersby Precautions
If a bystander comes within 300 feet of the tractor while the mower is being operated, stop the tractor at once,
idle the engine and disengage the PTO. Do not engage the PTO again until all bystanders are well past the
300 foot distance. OPS-R-0024
INTERSTATER 03/09
© 2009 Alamo Group Inc.
Operation Section 4-30
OPERATION
Flail Mowers are capable under adverse conditions of throwingobjects
for great distances (100 yards or more) and causing seriousinjury or
death. Follow safety messages carefully.
STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good,
workablecondition;
-Mower sections
or Wings are running close to and parallel to the ground
withoutexposed Blades;
NOTE: Where there are grass and weeds high enough to hide debris that could
bestruck by the blades, the area should be: inspected and large debris removed, mowed
atan intermediate height, inspected, closely with any remaining debris being removed,
andmowed again at desired final height. (This will also reduce power required to
mow,reduce wear and tear on the Mower drivetrain, spread cut material better,
eliminatestreaking, and make the final cut more uniform.) (SFL-6)
11.3 Engaging the Power Take Off (PTO)
Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement
must be completely lowered and the deck positioned at a safe operating height. NEVER engage the PTO with
the implement in the raised position.
Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to
the on position, and slowly increase the engine speed until the PTO is operating at the rated speed. If you
hear unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the
implement to determine the cause of the noise or vibration and repair the abnormality. OPS-U- 0027
Do not let the Blades turn when the Mower Deck is raised for any
reason, including clearance or for turning. Raising the Mower deck
exposes the Cutting Blades which creates a potentially serious hazard
and could cause serious injury or even death from objects thrown from
the Blades. (SRM-07)
Do not put hands or feet under mower decks. Blade Contact can result
in serious injury or even death. Stay away until all motion has stopped
and the decks are securely blocked up. (SGM-09)

OPERATION
11.4 PTO RPM and Ground Speed
OPERATION
Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut.
Recommended speed for efficient mower performance is between 2 and 5 mph(3-8 kph). Operate the mower
at its full rated PTO speed to maintain blade speed for a clean cut. Refer to the tractor operator’s manual or
the tractor instrument panel for the engine speed and gear to provide the required PTO and desired ground
speed. Make sure that the mower is operating at its full rated speed before entering the vegetation to be cut.
If it becomes necessary to temporarily regulate engine speed, increase or decrease the throttle gradually.
Ground speed is achieved by transmission gear selection and not by the engine operating speed. The
operator may be required to experiment with several gear range combinations to determine the best gear and
range which provides the most ideal performance from the mower and most efficient tractor operation. As the
severity of cutting conditions increase, the ground speed should be decreased by selecting a lower gear to
maintain the proper operating PTO speed. OPS-R-0025
Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause
Implement driveline or blade failures resulting in serious injury or death. (SG-26)
Mow at the speed that you can safely operate and control the tractor and mower. The
correct mowing speed depends on terrain condition and grass type, density, and height of
cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds
when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power
lines, or when debris and foreign objects are to be avoided. (SGM-07)
11.5 Operating the Mower
Only operate the mower from the tractor operator’s seat with the seatbelt securely fastened. The tractor must
be equipped with a ROPS in the raised position or a ROPS cab.
The mower is designed to cut vegetation up to 1-1/2” in diameter. Sharp blades will produce a cleaner cut and
require less power. Travel at a speed that allows the mower sufficient time to cut through the vegetation and
maintain the PTO operating speed to prevent overloading the mower and tractor. Choose a driving pattern
that provides the maximum pass length and minimizes turning.
Under certain conditions, tractor tires may roll some grasses down preventing them from being cut at the
same height as the surrounding area. When this occurs, reduce the tractor ground speed while maintaining
the operating speed of the mower. A slower ground speed will permit grasses to at least partially rebound and
be cut. Taking a partial cut and/or reversing the direction of travel may also help produce a cleaner cut.
Avoid mowing in the reverse direction when possible. In situations where the mower must be backed to
access areas to be cut, make sure there are no persons or other foreign debris behind the mower before
mowing in reverse. When mowing in reverse, operate the tractor and mower at a reduced ground speed to
ensure tractor and mower control is maintained. OPS-R-0026
INTERSTATER 03/09

OPERATION
Do not mow with two machines in the same area except with Cab tractors with the windows
closed. (SGM-11)
Avoid mowing in reverse direction when possible. Check to make sure there are no
persons behind the mower and use extreme care when mowing in reverse. Mow only at a
slow ground speed where you can safely operate and control the tractor and mower.
Never mow an area that you have not inspected and removed debris or foreign material.
(SGM-08)
Follow these guidelines to reduce the risk of equipment and grass fires
while operating, servicing, and repairing the Mower and Tractor:
-Equip the Tractor with a fire extinguisher in an accesible location.
-Do Not operate the Mower on a Tractor with an underframe exhaust.
-Do Not smoke or have an open flame near the Mower and Tractor.
-Do Not drive into burning debris or freshly burnt areas.
-Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating.
-Never allow clippings or debris to collect near drivelines, slip clutches, and gearboxes.
Periodically shut down the Tractor and Mower and clean clippings and collected debris from
the mower deck. (SGM-12)

OPERATION
Mow only in conditions where you have clear visibility in daylight or with adequate artificial
lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least
100 yards(90 m) in front and to the sides of the tractor and mower. Make sure that you can
clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions,
power lines, debris and foreign objects. If you are unable to clearly see these type of items
discontinue mowing. (SGM-1)
OPERATION
11.6 Shutting Down the Implement
OPERATION
To shut down the implement, first bring the tractor
to a complete stop. Then slow down the implement
by reducing the engine speed before disengaging
the PTO. Wait for all motion to stop before
proceeding to drive or shut down the tractor.
Park the tractor on a level surface, place the
transmission in park or neutral and apply the
parking brake, lower the attached implement to the
ground, shut down the engine, remove the key, and
wait for all motion to come to a complete stop
before exiting the tractor. OPS-F- 0011
12. DISCONNECTING THE MOWER FROM THE TRACTOR
Before disconnecting the mower, the PTO must be
disengaged and all motion at a complete stop.
Move the mower to a level storage location and
lower both wings to the ground. If the mower will
be stored with the sections in the raised position,
be sure that the locks are engaged. If the mower
is not resting securely on the ground, block the
mower up securely before attempting to
disconnect it from the tractor. Use extreme care to
keep feet and hands from under the mower and
clear of any pinch points. OPS-F-0012

OPERATION
After disconnecting the 3 lift points, remove the
mower driveline from the tractor PTO shaft. Lay
the driveline down carefully to avoid damaging
the driveline or its shield. Do not let the driveline
fall into mud or dirt, which can contaminate the
bearing and shorten the life of the driveline.

OPERATION
Never work under the Implement, the framework, or any lifted
component unless the Implement is securely supported or blocked up
to prevent sudden or inadvertent falling which could cause serious
injury or even death. (SG-14)
OPERATION
MOWER STORAGE
It is recommended that the mower be stored with the center section and both wings fully lowered to ground
level. If the mower is stored with the wings in the raised position, select a level area and install wing transport
braces to prevent the wings from falling BEFORE disconnecting the mower hitch from the tractor.
OPERATION
Properly preparing and storing the mower at the end of the season is critical to maintaining its appearance
and to help ensure years of dependable service. The following are suggested storage procedures:
•
•
•
•
•
•
•
Thoroughly clean all debris off the mower to
prevent damage from rotting grass and
standing water.
Lubricate all mower grease points and fill
gearbox oil levels as detailed in the maintenance section.
Tighten all bolts and pins to the recommended torque.
Check the mower for worn and damaged
parts. Perform repairs and make replacements immediately so that the mower will be
ready for use at the start of the next season.
Store the mower in a clean, dry place with
the mower housing resting securely on
blocks or at ground level.
Keep the driveline yoke from sitting in water,
dirt and other contaminants.
Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the mower.
It is critical that driveline clutches slip when an obstacle or heavy load is encountered to avoid mower and/or
tractor damage. If the mower sits outside for an extended period of time or is exposed to rain and/or humid
air, the clutch lining plates must be inspected to ensure they are not frozen together from rust or corrosion. If
the mower has been exposed to such conditions, at the start of each mowing season, and any time it is
suspected that the slip clutch plates may be frozen together, readjust the slip clutch as detailed in Seasonal
Clutch Maintenance of the maintenance section in this manual. OPS-F-0014
Never allow children to play on or around Tractor or Implement. Children can slip or fall off
the Equipment and be injured or killed. Children can cause the Implement to shift or fall
crushing themselves or others. (SG-25)

13. TRANSPORTING THE TRACTOR AND IMPLEMENT
Inherent hazards of operating the tractor and implement and the possibility of accidents are not left behind
when you finish working in an area. Therefore, the operator must employ good judgement and safe operation
practices when transporting the tractor and implement between locations. By using good judgement and
following safe transport procedures, the possibility of accidents while moving between locations can be
substantially minimized. OPS-U- 0017
Before transporting the tractor and mower, idle the
tractor engine, disengage the PTO and wait for all
mower moving parts to come to a complete stop.
Raise the mower sections and ensure transport
locks engage.

Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
OPERATION
OPERATION
Before transporting the tractor on a public roadway
or boarding a trailer for transport, the tractor brake
pedals should be locked together. Locking the
pedals ensures that both wheels brake
simultaneously while stopping, especially when
making an emergency stop.
Use extreme caution and avoid hard applications of
the tractor brakes when towing heavy loads at road
speeds. Never tow the implement at speeds
greater than 20 MPH (25 kph). OPS-U- 0018
If the tractor’s hydraulic pump is not independent of the tractor PTO, or if the tractor PTO has to be run to have
hydraulic power, disconnect the mower driveline from the tractor PTO output shaft. Secure the driveline to the
mower deck to prevent driveline damage or loss during transport.
13.1 Transporting on Public Roadways
Extreme caution should be used when transporting the tractor and implement on public roadways. The tractor
must be equipped with all required safety warning features including a SMV emblem and flashing warning
lights to alert drivers of the tractor’s presence. Remember that roadways are primarily designed for
automotive drivers and most drivers will not be looking out for you, therefore, you must look out for them.
Check your side view mirrors frequently and remember that vehicles will approach quickly because of the
tractor’s slower speed. Be extremely cautious when the piece of equipment that you are towing is wider than
the tractor tire width and/or extends beyond your lane of the road.
Make sure that a proper size safety tow chain is secured between the tractor and implement before entering a
public road. OPS-U- 0019
NOTE: Ensure that the mower sections are fully raised and that the transport locks are engaged for each
section.

DAILY CHECKS
MAINTENANCE
Before operating your Interstater, take the time to inspect and repair any damage to the machine or tractor.
Only a minimum of time and effort is required to regularly maintain this machine to provide long life and trouble
free operation.
1. Lubricate the INTERSTATER at the specified intervals as outlined in the lubrication diagram. Figure MntFL-0001. All mower grease fittings are equipped with lubricaps which snap over the grease fittings to prevent
dirt from entering the fittings. Remove the cap and wipe the fitting before greasing. Wipe the outlet of the
grease gun then grease the bearing. When finished, place the cap over the fitting and wipe any excess grease
from around the cap. In extremely dusty conditions, it is desirable to lubricate more often than every 8 hours.
Grease PTO shaft as outlined on the diagram located on PTO shaft shield. The idler pulleys are equipped with
a sealed ball bearing and require no further lubrication. Caster wheel bearings should be repacked at the end
of each mowing season and checked before the start of the next season. The gearbox is shipped with the
proper amount of SAE No. 90 extreme pressure lubricant. Maintain the level of this oil at the lower 1/8" pipe
plug on the gearbox cover. LUBRICATE MOWER BEFORE INITIAL USE.
NOTE: Lubricate flail roller bearing until lubricant can be seen coming out between roller and bearing housing.
2. Before each day's use, follow this procedure:
a. Visually check the unit, and make certain all items are properly tightened.
b. Check the pump drive belt tension. If necessary, tighten the belt as instructed in this section.
NOTE: Cutter unit belt tension is maintained by a spring-loaded idler pulley.
c. Check the reservoir fluid level with the cutter units in the transport position. The oil level should be even with
the sight glass located on the reservoir. Before removing filler cap, wipe the top of the reservoir to prevent dirt
from entering the tank. Use Chevron 1000 THF or an equivalent.
NOTE: Your ambient temperature and operating conditions may require a different viscosity oil. Please consult
the oil manufacturer for proper specifications.
NOTE: If the reservoir needs oil, a leak exists somewhere in the system. Repair the leak before using the unit.
d. Check the cuttershaft to make certain it is fully knifed. Replace any missing knives or cotter pins, then run
the unit at full speed to check for vibrations. Do not operate the unit in an out-of-balance condition.
Never work under the Implement, the framework, or any lifted
component unless the Implement is securely supported or blocked up
to prevent sudden or inadvertent falling which could cause serious
injury or even death. (SG-14)

MAINTENANCE
CUTTER UNIT
A. GENERAL
The INTERSTATER electrical circuit controls the flow of oil to the hydraulic motor on the cutter unit. The motor
control valve relies on a solenoid to control the spool within the valve and direct the flow of oil.
MAINTENANCE
When the mower ON/OFF switch is in the "ON" position, current flows to the solenoid which positions the spool
to direct the oil flow from the pump to the motor. The oil then turns the motor which drives the cuttershaft.
When the mower ON/OFF switch is in the "OFF" position, the solenoid is not energized and oil pressure in the
power circuit pushes the spool back allowing the oil to return to the reservoir from the valve. Without the flow of
oil, the motor will no longer drive the cuttershaft.
B. OFF-ON SWITCH
The electrical circuit is connected to the tractor ignition switch. (See Electrical Schematic). The yellow wire
connects to the switch accessory terminal and the red wire connects to the start terminal. A 6 amp in-line fuse
on the yellow wire protects the off-on switches from an overload. THE OFF/ON SWITCH HAS A SAFETY
LOCK-OUT FEATURE THAT WILL NOT ALLOW THE TRACTOR STARTER TO ENGAGE IF SWITCH IS IN
THE ON POSITION.
C. SAFETY CUT-OFF SWITCH
In the electrical circuit between the OFF-ON switch and the motor solenoid valve is a safety cut-off switch.
This switch is a cam-operated electrical switch that cuts the wing mowers off when the wing is raised to
approximately 60 degree angle. This also prevents mower from being operated with the wing up. This feature
prevents injury due to inadvertently starting mower with wing raised and should be kept in proper operating
condition.
D. SOLENOID OPERATED VALVE AT MOTOR
The electric solenoid valve is mounted in the hydraulic motor manifold block. The solenoid controls the spool
within the valve. When the off-on switch is on and the wing is lowered the solenoid in energized by electrical
current and the spool is closed to direct the flow of oil from the pump through the cuttershaft hydraulic motor.
The wing activates the safety cut-off switch, the electrical current is removed from the solenoid causing the
spool to open and allows oil to return to tank without being directed through the motor. Without oil flow through
the motor, the cuttershaft will not operate.
GENERAL MAINTENANCE
Mowing is accomplished by a series of knives which rotate at high speed on a shaft. The shaft is driven by a
hydraulic motor through a set of drive belts. Belt tension is maintained by a spring-loaded idler pulley.
The cutter unit is mounted to the lift frame by two mounting pins and held in place by a hydraulic cylinder. This
cylinder is used to tilt the cutter unit to allow mowing on an angle and tilting to the vertical position for
transporting. Another hydraulic cylinder is mounted to the lift frame and the lift cylinder support. This cylinder is
used to raise the cutter unit via the lift frame.
The cutter unit rides on a large roller assembly. The position of this roller is adjustable and will determine the
cutting height of the knives.

HYDRAULICS
General
The INTERSTATER hydraulic system consists of two circuits. The power circuit drives the cuttershaft. The
control circuit lifts and tilts the cutter unit.
MAINTENANCE
A tractor with a cutter unit installed on each side will have two independent power circuits with two sets of lift
and tilt cylinders, and one control circuit with a four-section control valve (instead of a two section valve).
NOTE: It is important that pipe thread sealant be used on solid connections only; never on connections
between swivel fittings or fittings with “O” rings and straight threads. Use pipe thread sealing compound. DO
NOT substitute other types of sealant, such as teflon tape, paint, shellac, etc.
Initial Start-Up Procedures
Whenever the hydraulic system is drained in order to service a hydraulic component, the following start-up
procedure should be completed.
1.
Check all nuts and hex head capscrews to be sure they are tight and that all lock washers are fully
compressed.
2.
Check all hoses and hydraulic connections to be sure that they are tight.
3.
Inspect all moving parts, and make certain that no wires or hoses will be caught or pinched when the
tractor is in operation.
Secure all wires and hoses.
4.
Thoroughly lubricate the INTERSTATER. Refer to SECTION 2, Illustration 4.
5.
Change the hydraulic filter and fill the reservoir to the sight glass with new hydraulic oil. Refer to SECTION
1 for specifications.
Remove all objects from, and stand clear of the front of the cutter unit. DO NOT GET NEAR
ROTATING KNIVES.
6.
Turn mowers off, then start tractor and run engine at low idle. Operate the lift and tilt circuits, and the
power circuit (turn cutter units on ONLY when mowers are fully lowered). Operate until the system is fully
charged. Recheck the fluid level and add oil, if necessary. If undue noise continues after the system is fully
charged, stop the unit and determine the cause.
7.
After the hydraulic system is fully charged and functioning properly, switch the mowers on and increase
the engine speed to run the PTO at 540 RPM. Maintain this speed for 5 minutes and look for any leaks or
possible problems.

and checked with the cutter unit in the transport position. The oil temperature should not exceed 180 deg.F.
The oil return hoses are connected to the hydraulic filter on top of the reservoir. Oil is returned from cutter unit
cooling tubes and filtered before entering the hydraulic reservoir. Oil returning from the control circuit also
enters the reservoir thru the filter. Use Chevron 1000THF or an equivalent.
Note: Your ambient temperature and operating con ditions may require a different viscosity oil. Please consult
the oil manufacturer for proper specifications.
Solenoid Control Valve
The solenoid control valve directs oil flow from the
hydraulic pump. When the mower ON/OFF switch
is in the "ON" position, the solenoid is energized
and the spool within the valve is positioned to direct
oil to the cuttershaft motor.
When the mower ON/OFF switch is in the "OFF"
position, oil pressure within the valve pushes the
spool back which allows the oil to circulate through
the cutter unit before returning to the reservoir.
When the flow of oil to the motor is cut off, the
cuttershaft will stop rotating. Figure Mnt-FL-0017

Checking Solenoid Valve
1. With engine running, turn the mower ON/OFF switch in the "ON" position. Check voltage level at the
solenoid.
2. If it is less than 12 volts, check wiring and ground connections. Checking ground wire is as important as
checking the hot wire. If voltage is sufficient, the solenoid valve is bad and will need to be replaced.

CONTROL CIRCUIT
Lift and Tilt Cylinders
MAINTENANCE
Hydraulic cylinders change the position of the cutter unit.
The lift cylinder raises and lowers the unit by changing
position of the lift frame. To lift unit, oil is supplied to rod side
of cylinder. Gravity lowers unit when lift levers are in
"DOWN" position.
The tilt cylinder changes the angle of the cutter unit. Oil is
supplied to both ends of the cylinder and provides power to
tilt the unit up or down. The unit can be tilted to the full
vertical position for transport.
Lift Cylinder (3-1/4” O.D.)
Tilt Cylinder (3-3/4” O.D.)
Disassembly or Lift or Tilt Cylinder
For part numbers and illustration, refer to the Parts Listing section.
1. Disconnect hoses at cylinder. Cap all hoses to prevent fluid contamination. Remove cylinder from unit.
2. Remove reducer bushing and snap ring which retains the rod guide. Remove rod guide, rod, and piston.
Remove guide and piston from rod.
3. Replace all "O" rings, back-up washers, and rod wiper. Inspect rod, guide, piston, and body for damage.
4. Clean inside of cylinder with mineral spirits. DO NOT wipe dry; air dry instead. Lint, dirt, and, grit can cause
immediate or premature failure.
5. Lubricate all parts with clean hydraulic oil and reassemble.
Cylinder Rod Maintenance
It is important to visually inspect the hydraulic cylinder rods daily before use. It is highly recommended that
while the machine is stored or getting very little use that a protectant is applied to the hydraulic cylinder rods to
prevent degradation. If the machine receives more frequent use, be sure to fully cycle each cylinder function so
that the cylinder rod is coated by the systems hydraulic fluid. Depending on your operating environment it may
be necessary, under normal operating conditions, to apply a protective lubricant to the cylinder rods for
protection against rust and pitting. Hydraulic fluid may provide a suitable amount of protection, but remember
any protectant can attract dust and debris so attention must be given to the cylinder rods daily. Also remember
that any other protectant must be compatible with hydraulic fluid. Alamo Industrial is not responsible for rust or
pitting of the cylinder rod due to weather exposure or impacts from normal operation or mounting. If hydraulic
cylinders and or the cylinder rods are damaged as a result of the rods rusting or pitting, the hydraulic cylinders
and rods will not be covered under warranty by Alamo Industrial.

Hydraulic Gear Pump
NOTE: The gear pump is not used when tractor
hydraulics are used to power the control circuit.
Sectional Control Valve
The control valve directs oil flow from the gear
pump to the hydraulic cylinders. In the "HOLD"
position, the spool blocks oil flow to the cylinders
which prevents movement, and directs oil through
the valve back to the reservoir.
When the spool is shifted, oil flows to one side of
the cylinder while the other side is opened to the
return line. The cylinder rod then moves in or out
and changes the cutter unit's position.
In the "FLOAT" position, the spool will open both
sides of the cylinder to the return line. The cylinder
rod is then free to move since oil can enter or leave
either side of the cylinder.
There are two valve sections for each side of the
tractor. One is for TILT, one is for LIFT. The sections
are bolted together between an inlet and an outlet
section. The LIFT section has three positions: UP,
HOLD and DOWN & FLOAT. The TILT section has
four positions: UP, HOLD, OUT and FLOAT.
A pressure relief valve is mounted in the inlet section of the valve. When a cylinder is bottomed, the relief valve
will open and allow oil from the gear pump to return to the reservoir.
INTERSTATER 03/09

Maintenance Section 5-23
MAINTENANCE
The gear pump, mounted to the pump mount and
driven by the crank shaft pulley, produces oil flow
for the control circuit. The gear pump inlet is
connected, via a hose, to the reservoir which
supplies control circuit oil. A high pressure hose
connects the pump outlet to the sectional control
valve inlet.
MAINTENANCE
Checking Relief Valve Pressure
1. To check the relief valve pressure setting, remove inlet hose at the control valve. Install a tee fitting and
reconnect the hose to a pressure gauge.
2. Check for proper tension on front drive belts (1/4 inch play at midpoint).
3. Start engine and run at low idle.
MAINTENANCE
4. Raise the Tilt cylinder and note the pressure when the cylinder bottoms.
5. The pressure should be the same on both circuits, 1200 psi. If the pressure is 1200 psi on one and not on
the other, the relief valve and the pump are working fine. The problem would be somewhere else.
6. If pressure is low on both circuits, adjust relief valve. Remove hex cap, loosen lock nut (if present) and turn
adjusting screw clockwise.
7. If the pressure does not increase, remove the relief valve and inspect it. If the valve is good, the gear pump
is worn.

External Coil Slip Disk Replacement
A. TO DISASSEMBLE EXTERNAL COIL SPRING CLUTCH (Figure Mnt-FL-0024)
Before beginning disassembly, remove or fold shields out of the way and clean off dirt and trash from the
area.
1. Remove two Attaching Bolts (6). Remove Clutch Assembly from shaft of Gearbox. Leave Driveline or
Driveline Half attached to Clutch.
3. On the opposite side, Outer Flange (2) will slide off which will allow Clutch Plate (3) to slide over notches
on outside diameter of Clutch Body (5).
4. Remove Plate with six bolt holes (7). Note: Bolts (1) go through these holes.
5. Remove the four Friction Disks (4) and discard. DO NO RE-USE.
B. TO CLEAN AND INSPECT
1. Inspect all components for rust, wear, or damage. Check Spacer (8) for scoring or excessive wear. Clean
Clutch Plates and Drive Plates with a wire brush as required to remove any rust.
C. TO REASSEMBLE
1. After all parts have been inspected, cleaned or replaced as necessary, replace components in reverse
order from disassembly USING THE NEW, IMPROVED DISKS. Do not tighten the six Adjusting Nuts and
Bolts (1) until assembly is complete.
D. TO ADJUST
To adjust Slip Clutch, tighten Bolts (1) until the Nut makes contact with Compression Spring (10).
1. After all six Bolts have been assembled so that Nuts contact Springs, mark the position of the top flat on
each Nut. Tighten Nuts 1-3/8 turns as follows: Do NOT tighten one bolt completely. Tightening as shown in
rotation will put equal pressure all the way around on Friction Disks and Drive Plates.
a. Tighten the Nuts (1) one-half turn in rotation.
b. Tighten one-half turn again until the marks on the Nuts are on top as in the beginning.
c. Then, carefully tighten 3/8 of a turn. As a double check, the Springs should now be
COMPRESSED TO 1-11/32" (1.34") TO 1-5/16" (1.31") long.
1. Re-assemble Clutch to Gearbox. Tighten Bolts (6) securely.
2. Clutch slips too easily, STOP PTO AT ONCE. Tighten each Adjusting Nut (1) NO MORE THAN ¼ TURN
AT A TIME. NEVER TIGHTEN SPRINGS SHORTER THAN 1-9/32" (1.28") LONG EVEN AFTER DISK
WEAR.
NOTE: EXCESSIVE SLIPPING WILL BURN UP DISKS AND SLIP CLUTCH TO THE POINT WHERE THE
CLUTCH IS NOT REPAIRABLE. HOWEVER, EXCESSIVE TIGHTENING WILL PREVENT THE SLIP
CLUTCH FROM SLIPPING AND CAN LEAD TO FAILURES OF DRIVETRAIN COMPONENTS WITH
RESULTING DOWNTIME.
E. TO REPLACE SHIELDS
1.
Make certain that all Driveline Canopy Shields are in good repair and rotate smoothly on the
Drivelines. Replace Bearings and/or Integral Shields if necessary.
2.
Re-install Gearbox Canopy Shields with the same hardware and tighten securely.

2. Loosen six Adjusting Bolts (1). LOOSEN EACH BOLT A FEW TURNS AT A TIME - NOT ALL AT ONCE.
Continue in rotation until Nuts are loose. Remove these Bolts. Flange Yoke (9) will slide off. On Clutches
that have Dust Shields (11), Shields will slide off with Flange Yoke. Note: Some types do not have Dust
Shields.
MAINTENANCE
Slip Clutch
A slip clutch is incorporated in the PTO driveline. It is designed to slip, absorb the shock load, and protect the
driveline.
MAINTENANCE
After the first hour of operation, the slip clutch should be checked for overheating. After this first check, the
slip clutch should be checked weekly or anytime there is overheating. To adjust the slip clutch, tighten the
spring bolts 1/8 (maximum) turn at a time. Bolts should NEVER be adjusted to the point where the springs are
compressed solid. Minimum spring length is 1-1/8".
The slip clutch should be checked periodically and adjusted to compensate for wear. The lining plates are 1/8"
thick when new. Replace after 1/32" wear. If the mower has been idle for an extended period of time, or in wet
weather, before operating check to be sure the friction lining plates are not frozen or rusted together. Should
this freezing occur refer to the procedure described in the "Seasonal Clutch Maintenance" section on the next
page.
There are four friction lining plates in the slip clutch. These should be checked weekly for oil or grease, wear,
and moisture which could cause corrosion on the drive plates.

SEASONAL CLUTCH MAINTENANCE
It is important that the clutch lining plates slip when an obstacle or load heavier than clutch setting is
encountered. Therefore, if the machine sits outside longer than 30 days and is exposed to rain and/or humid
air it is important to make sure that the clutch lining plates are not rusted/corroded together. Before using the
mower use the following procedure to make sure the clutch will slip and give the overload protection required.
1. Loosen nuts on springs until the springs can freely rotate, yet remain secure on bolts.
2. Attach mower to tractor and start the tractor. Set the engine speed at 1200 RPM.
4. Engage the PTO (approximately one second) and then quickly disengage it. The friction lining plates
should break loose (check the mark).
5. Turn tractor off and tighten the nuts on the springs to their original position of 1-5/16" compressed spring
length.
A double wing Interstater with 74" wing mowers will require approximately 26 gallons of oil to fill the hydraulic
tank, hoses, cylinders and cooling tubes in the mower deck. An Interstater with 60" wings will require less oil
and with 88" wings will require more oil. The Hydraulic tank only holds 15 gallons of oil and you can not add
enough oil to the tank the first time to completely fill the system. Oil should be changed after the first 200 hours
of operation and every 400 hours of 12 months of operation thereafter.
The following filling instructions must be carefully followed to prevent pump cavitation and instant pump failure.
1.
After the Interstater mower is completely assembled to the tractor and with the wings on the ground, fill the
mower hydraulic tank above the oil level sight gauge approximately 5" or 1" below the top of the tank.
2.
Start the tractor and run it for 30 to 45 seconds and then turn it off.
3.
Check the oil level in the sight gauge. If no oil is seen, add oil to bring the level up to the sight gauge.
NOTE: Do not fill the tank with oil above the level of the sight gauge after the first filling. Overfilling the tank
with oil after the initial filling may result in oil being discharged through the air filter on top of the hydraulic tank.
4.
Start the tractor and run it for 2 minutes and then turn it off.
5.
Again check the oil level in the sight gauge. If the oil level is in the sight gauge, the unit is ready to run. If
no oil is seen, add oil to bring the level up to the sight gauge.
6.
Repeat steps 4 and 5 as required until the oil level stabilizes at the level of the sight gauge.

REQUIRED OF THE OWNER:
1. Provide a Roll-Over-Protective Structure that meets the requirements of this Standard; and
2. Provide Seat belts that meet the requirements of this paragraph of this Standard and SAE J4C; and
3. Ensure that each employee uses such Seat belt while the tractor is moving; and
4. Ensure that each employee tightens the Seat belt sufficiently to confine the employee to the protected
area provided by the ROPS.

Securely fasten seat belt if the tractor has a ROPS.
Where possible, avoid operating the tractor near ditches, embankments, and holes.
Reduce speed when turning, crossing slopes, and on rough, slick, or muddy surfaces.
Stay off slopes too steep for safe operation.
Watch where you are going - especially at row ends, on roads, and around trees.
Do not permit others to ride.
Operate the tractor smoothly - no jerky turns, starts, or stops.
Hitch only to the drawbar and hitch points recommended by the tractor manufacturer.
When the tractor is stopped, set brakes securely and use park lock, if available.
Keep children away from danger all day, every day...
Equip tractors with rollover protection (ROPS) and keep all machinery
guards in place...
Please work, drive, play and live each day with care and concern for
your safety and that of your family and fellow citizens.
