In order to reduce accidents and enhance the safe operation of mowers, Alamo Group Ag Division, 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 Ag 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 Group Ag.

Safety Messages
SAFETY
A safe and 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 safely and 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.

Safety Section 1-2
SAFETY
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)
Always maintain the safety signs in good readable condition. If the safety signs are
missing, damaged, or unreadable, obtain and install replacement safety signs immediately.
(SG-5)
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)
Do not modify or alter this Implement. Do not permit anyone to modify or alter this
Implement, any of its components or any Implement function. (SG-8)
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)

Safety Section 1-3
SAFETY
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
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)
SAFETY
Do not mount 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 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)
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)
GR60/72 02/07

Safety Section 1-4
SAFETY
Periodically inspect all moving parts for wear and replace when
necessary with authorized service parts. Look for loose fasteners, worn
or broken parts, and leaky or loose fittings. Make sure all pins have
cotter pins and washers. Serious injury may occur from not maintaining
this machine in good working order. (SG-21)
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 towing this equipment.
•
Test the equipment at a slow speed in turns. Increase the speed through the turn only
after you determine that it is safe to operate 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 safe 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)
Never attempt to lubricate, adjust, or remove material from the Implement while it is in
motion or while tractor engine is running. Make sure the tractor engine is off, the
transmission in park, the parking brake set, and that the key is with you before working on
the implement. (SG-20)
GR60/72 02/07

Safety Section 1-5
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
Always read carefully and comply fully with the manufacturer’s
instructions when handling oil, solvents, cleansers, and any other
chemical agent.
(SG-22)
SAFETY
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health. (SG-23)
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)
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)
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)
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 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)

Safety Section 1-6
SAFETY
There are obvious and hidden potential hazards in the operation of this
Mower. REMEMBER! This machine is often operated in heavy brush
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. (SGM-2)
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-5)
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-6)
Mow at the speed that you can safely operate and control the tractor and mower. Safe
mowing speed depends on terrain condition and grass type, density, and height of cut.
Normal ground speed range is from 2 to 5 mph. 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-7)
GR60/72 02/07
© 2007 Alamo Group Inc.
Safety Section 1-7
SAFETY
All Safety Shields, Guards and Safety devices including (but not
limited to) - the Deflectors, Chain Guards, Steel Guards, Gearbox
Shields, PTO integral shields, and Retractable Door Shields should be used and
maintained in good working condition. All safety devices should be inspected
carefully at least daily for missing or broken components. Missing, broken, or worn
items must be replaced at once to reduce the possibility of injury or death from thrown
objects, entanglement, or blade contact. (SGM-3)
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-8)
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. (SGM-9)
Replace bent or broken blades with new blades. NEVER ATTEMPT TO STRAIGHTEN,
WELD, OR WELD HARDFACING ON BLADES SINCE THIS WILL LIKELY CRACK OR
OTHERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLE SERIOUS INJURY
FROM THROWN BLADES. (SGM-10)
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-7)
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)
GR60/72 02/07

Safety Section 1-8
SAFETY
Rotary Mowers are capable under adverse conditions of throwing
objects for great distances (300 feet or more) and causing serious injury
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, workable
condition;
-Mower sections or Wings are running close to and parallel to the ground without exposed
Blades;
-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 be struck
by the blades, the area should be: inspected and large debris removed, mowed at an
intermediate height, inspected, closely with any remaining debris being removed, and
mowed 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, eliminate streaking, and
make the final cut more uniform). (SRM-1)
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. (S3PT-2)
There are obvious and hidden potential hazards in the operation of this Implement as in all
power-driven or pulled equipment. REMEMBER! This machine is often operated in rough
terrain conditions that include tall grass, weeds, gullies, holes, slopes, hidden obstructions
and the like. Serious injury or even death may occur unless care is taken to assure the
safety of the operator and bystanders in the area. Do not operate this machine with anyone
in the immediate area. (S3PT-7)
Make sure the PTO shield, integral driveline shields, and input shields are
is installed when using PTO-driven equipment.
Always replace any
shield if it is damaged or missing. (S3PT-8)
GR60/72 02/07

Safety Section 1-9
SAFETY
-Passersby are outside the existing thrown-object zone;
SAFETY
Relieve hydraulic pressure prior to doing any maintenance or repair work
on the Implement. Place the Implement on the ground or securely
blocked up, disengage the PTO, and turn off the tractor engine. Push and pull the Remote
Cylinder lever in and out several times prior to starting any maintenance or
repair work. (S3PT-9)
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!”
Always disconnect the main PTO Driveline from the Tractor before performing service on
the Implement. Never work on the Implement with the tractor PTO driveline connected and
running. Rotating Parts, Blades or Drivelines could turn without warning and cause immediate entanglement,
injury or death. (S3PT-11)
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)
Do not mow with two machines in the same area except with Cab tractors with the windows
closed. (SGM-11)
Replace bent or broken blades with new blades. NEVER ATTEMPT TO STRAIGHTEN,
WELD, OR WELD HARDFACING ON BLADES SINCE THIS WILL LIKELY CRACK OR
OTHERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLE SERIOUS INJURY
FROM THROWN BLADES. (SGM-10)

maintenance, and operating practices, as described in this manual, will help the owner/operator get years of
satisfactory service from the machine.
The purpose of this manual is to familiarize, instruct, and train. The Assembly Section instructs the owner/
operator in the correct assembly of the Cutter using standard and optional equipment. The Parts Listing
section is designed to familiarize the owner/operator with replaceable parts on the Cutter. This section
provides exploded assembly drawings of each Cutter component illustrating each piece and the corresponding
part number.
Careful use and timely service saves extensive repairs and costly downtime losses. The Operations and
Maintenance sections of the manual trains the owner/operator how to work the Cutter correctly and attend to
appropriate maintenance. The Trouble-Shooting Guide helps diagnose difficulties with the Cutter and offers
solutions to the problems.
Safety is of primary importance to the owner/operator and to the manufacturer. 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. Many of the Safety Messages will be repeated throughout the manual. The owner/operator/dealer
should know these Safety Messages before assembly and be aware of the hazards of operating this blade
during assembly, use, and maintenance. The Safety Alert Symbol combined with a Signal Word, as seen
below, is intended to warn the owner/operator of impending hazards and the degree of possible injury faced
when operating this machine.

INTRODUCTION
INTRODUCTION
These rugged Cutters are designed for heavy-duty work. They can mow pastures, cut brush up to 3" (GR60)
and 4" (GR72) in diameter, and control grass and weeds on highways or industrial sites.
For Non-Agricultural use, OSHA, ASAE, SAE, and ANSI standards require the use of Chain
Guards or Solid Skirts at all times. The Cutter manufacturer strongly recommends the use
of Chain Guards or Solid Skirts for Agricultural purposes as well, to reduce the risk of
property damage, serious bodily injury, or even death from objects thrown out by or from
contact with the Cutting Blades.
The 60" machine requires a minimum of 30 HP for both 540 and 1000 RPM machines. The 72" Cutter requires
at least 35 HP for 540 and 1000 RPM machines. The maximum allowable horsepower for either size is 120HP.
At least 20% or the tractor’s weight must be on the front tires with the implement lifted to
provide adequate traction for safe steering under good conditions. Slow down on hills,
rough terrain, and curves.
Front and rear, and left and right are determined by the normal direction of travel (the same as on your
automobile).

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 mower 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 mower. Never operate the tractor PTO with
the PTO master shield missing or in the raised position. OPS-U- 0004

OPERATION
3.3 Tractor Horsepower
The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing
conditions, the GR60/72 mower requires at tractor with at least 30 and 40 HP, respectively. Operating the
mower with a tractor that does not have adequate power may damage the tractor engine. Exceeding 90 HP
may cause mower damage by overpowering the unit in heavy cutting conditions.
OPERATION
3.4 3-Point Hitch
The tractor 3-point hitch must be rated to lift at least
1370 lbs. if attaching a GR60 and 1578 lbs. if
attaching a GR72 mower.
GR60/72 mowers can attach to tractor’s with either
a CAT I or II hitch. Refer to the tractor operator’s
manual for the category of the tractor used. If the
hitch does not conform to ASAE Cat I or II
dimensions, the mower may not fit or raise properly.
Consult an authorized dealer for possible
modification procedures to mount nonconforming
hitches.
Use the correct hitch pins for the hitch category
being used. For a Cat I hitch, 7/8” lower and 3/4”
upper diameter hitch pins are used and Cat II
hitches require 1-1/8” lower and 1” upper diameter
hitch pins.

3.5 Front End Weight
A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end
weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the
front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front
weights and weight carriers can be purchased through an authorized tractor dealership. OPS-U- 0005
GR60/72 02/07

Operation Section 4-6
OPERATION
3.6 Power Take Off (PTO)
Depending on the unit, the mower is designed to operate at a PTO speed of 540 or 1000 RPM. Most tractors
operate at either 540, or a combination of 540 and 1000 RPM PTO speeds. The operating speed of the
mower and tractor can be determined by the number of splines on the driveline yoke and PTO output shaft.
Those operating at 540 RPM will have a 6-spline shaft and those operating at 1000 RPM will have a 21-spline
shaft. Note: The mower will not operate on tractors equipped with a 1000 RPM 20-spline, 1-3/4” shaft. Refer
to the tractor owner’s manual for instructions to change PTO speeds on models that operate at more than one
speed.
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 Mower resulting in
excessive vibration, thrown objects, and blade and mower 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)
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 the Tractor while the tractor is moving. Mount the Tractor
only when the Tractor and all moving parts are completely stopped. (SG-12)
GR60/72 02/07
© 2007 Alamo Group Inc.
Operation Section 4-7
OPERATION
If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an
over-running clutch must be used between the PTO output shaft and the driveline of the mower. An
authorized tractor dealer can provide the over-running clutch and its installation if needed. OPS-U- 0006
OPERATION
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.
OPERATION
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)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
4.2 Dismounting the Tractor
Before dismounting, park the tractor and implement on a reasonably level surface, apply the parking brake,
idle the engine down, disengage the PTO, and lower the implement to the ground. Shut down the tractor
engine according to the operator’s manual, remove the key, and wait for all motion to completely stop. Never
leave the seat until the tractor, its engine and all moving parts have come to a complete stop.
Use hand rails and steps when exiting the tractor. Be careful of your step and use extra caution when mud,
ice, snow or other matter has accumulated on the steps or hand rails. Use all handrails and steps for support
and never rush or jump off the tractor. OPS-U- 0009
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)

OPERATION
5. STARTING THE TRACTOR
The operator must have a complete understanding of the placement, function, and operational use of all
tractor controls before starting the tractor. Review the tractor operator’s manual and consult an authorized
dealer for tractor operation instructions if needed.
Essential Tractor Controls:
• Conduct all pre-start operation inspection and service according to the tractor operator’s manual.
• Make sure all guards, shields, and other safety devices are securely in place.
• The parking brake is on.
• The PTO control lever is disengaged.
• The 3-point hitch control lever is in the lowered position.
• The hydraulic remote control levers are in the neutral position.
• The tractor transmission levers are in park or neutral.
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.
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

Board the tractor and start the engine.
Position the tractor to the mower with the 3point 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.
Turn off the tractor engine and dismount.
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.
Walk around to opposite side and repeat
procedure for remaining lift arm and hitch pin.
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.
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.
NOTE: Offset Adaptor Hitches are available to position the mower to the left or right. Mowers with Offset
Adaptor hitches connect to the 3-Point hitch the same way as the mower A-frame. See Offset Adaptor Hitch in
the Assembly Section for details to equip the mower with this feature.
7. SETTING THE MOWER
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

Securely block up the mower at this height.
Remove the bolts securing the tailwheel
beam positioning bracket to the support
brackets and allow the tailwheel to rest at
ground level. Align beam and positioning
brackets holes with closest set of holes in
support brackets and reinstall bolts securing
the beam in position. Tighten all bolts and
nuts.
Extend the tractor’s top 3-point link so that
when lifting the mower, the front of the deck
will raise 2 to 2½" before the tail wheel leaves
the ground. This will allow the mower to
follow the contour of uneven terrain.
NOTE: Install optional check chains when there is
a problem with the hydraulic 3-Point lift maintaining
a set height or when a constant pre-adjusted cut
height is required. See Check Chains in the
Assembly Section for this accessory.

Park the tractor and mower on level ground.
Using the 3-point hitch control lever, position
the front of the mower with the side skids 1”
less off the ground than desired cut height.
For example, for a 3” cut, position the skids 2”
from the ground. Set the 3-point control lever
stop at this position to maintain this height
when raising and lowering the mower.
Shut down the tractor and remove the key.
Level the mower deck front to rear by
extending or retracting the 3-point top link.
OPERATION
7.2 Setting Deck Pitch
To facilitate safe and efficient operation, the mower
should be operated with the deck approximately
3/4” LOWER IN THE FRONT THAN THE REAR.
The correct deck pitch is obtained as follows:
OPERATION
1. Lower the mower until the rear of the mower is
resting securely on its tail wheel.
2. Then slowly lower the 3-point lift arms further
until the front of the mower is at least 3/4” lower
than the rear of the mower.
3. Place the tractor’s 3-point control lever stop at
this position so that each time the mower is raised
and lowered the deck pitch will be maintained.
Operating the mower with the front of the deck slightly lower than the rear allows the mower to cut the grass
only once and requires less work from the tractor. In addition, a more even distribution of the clippings from
the rear of the mower will be achieved with this angle. OPS-R-0002_B
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. OPS-R-0003_A
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. 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)

Operation Section 4-12
OPERATION
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 drive line can cause personal injury. (S3PT-18)
“Bottoming Out” Check Procedure
•
•
•
•
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.
Reattach the driveline to the PTO Shaft.
Raise the mower and watch the driveline as it
approaches the mark. If the distance between
the mark and the end of the outer shield tube
becomes less than 2” at any point, the driveline
must be shortened. OPS-R-0004_A
GR60/72 02/07
© 2007 Alamo Group Inc.
Operation Section 4-13
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 9” must be maintained.
OPERATION
GR60 Mowers Only
Shorten the driveline profiles as follows:
OPERATION
•
•
•
•
•
•
•
Remove the driveline from the tractor.
Raise and lower the mower to find the position
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.
GR72 Mowers
The GR72 driveline is a bar and welded sleeve assembly and its length cannot be modified as described
above. Contact your authorized dealer or Rhino Customer Service for recommendations to fit the mower to
the tractor if there is a potential problem bottoming out the driveline.
Engagement Check Procedure
•
•
•
•
•
With the driveline attached, position the mower to the point where the telescoping driveline is at its
maximum extension. Turn off the tractor and securely block the mower at this 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 9”, 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: When raising the mower, at least 1” clearance must be maintained between the driveline and the
mower deck. If necessary, place an upper lift stop on the 3-point hitch control lever to limit the height the
mower can be raised. OPS-R-0005_B

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
Periodically inspect all moving parts for wear and replace when
necessary with authorized service parts. Look for loose fasteners, worn
or broken parts, and leaky or loose fittings. Make sure all pins have
cotter pins and washers. Serious injury may occur from not maintaining
this machine in good working order. (SG-21)
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

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 towing this equipment.
• Test the equipment at a slow speed in turns. Increase the speed through the turn only
after you determine that it is safe to operate 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 safe 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)

OPERATION
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.
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.

10.4 Driving the Tractor and Mower
Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the
tractor and mower. 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.
Perform turns with the tractor and mower at slow
speeds to determine how the tractor with an
attached mower 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
mower 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.

Using the tractor 3-point hitch control lever, raise
the mower off the ground about 6”, or just high
enough to clear any ground obstacles. When
raising the mower, make sure all connection points
are securely attached and at least 1” clearance is
maintained between the driveline and the deck. If
necessary, place an upper lift stop on the 3-point
hitch control lever to limit the height the mower can
OPERATION
OPERATION
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. (S3PT-2)
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 wings should be
fully lowered for a lower center of gravity and added
stability. OPS-R-0021

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

crossing path.
resulting in possible damage and premature wear.
OPS-R-0022
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-5)
GR60/72 02/07

Operation Section 4-27
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
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-6)
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-R-0023
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
GR60/72 02/07

Operation Section 4-28
OPERATION
Rotary Mowers are capable under adverse conditions of throwing
objects for great distances (300 feet or more) and causing serious injury
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, workable
condition;
-Passersby 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 be struck
by the blades, the area should be: inspected and large debris removed, mowed at an
intermediate height, inspected, closely with any remaining debris being removed, and
mowed 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, eliminate streaking, and
make the final cut more uniform). (SRM-1)
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-7)
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-9)

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. 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. Safe
mowing speed depends on terrain condition and grass type, density, and height of cut.
Normal ground speed range is from 2 to 5 mph. 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-7)
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 4” 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_B
GR60/72 02/07

Operation Section 4-30
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 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)
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)
When you get to the end of a pass, slightly raise the
mower (2-4”) before turning. Never raise the
mower entirely while the blades are turning. If the
mower must be raised higher than 12” from ground
level, disengage the tractor PTO and wait for all
mower rotation to come to a complete stop before
proceeding to raise the mower.
When turning, the angle between the tractor and
mower should not be so great that a clattering of
the U-joints occurs.
Sharp turns can cause
premature failure of the joints and place pressure
on the tractor PTO shaft and could cause extensive
mechanical damage to the mower and tractor.

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.
12. DISCONNECTING THE MOWER FROM THE TRACTOR
Before disconnecting the mower, the PTO must be
disengaged and blade rotation at a complete stop.
Move the mower to a level storage location and
lower it to the ground. If the mower is not resting
securely on the ground, block the mower up
securely before attempting to disconnect it from
the tractor.

•
•
•
•
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-R-0032_A
14. TRANSPORTING THE TRACTOR AND IMPLEMENT
Inherent dangers 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

14.1 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 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)
The SMV (Slow-Moving Vehicle) emblem is
universal symbol used to alert drivers of the
presence of equipment traveling on roadways at a
slow speed. SMV signs are a triangular bright
orange with reflective red trim for both easy day and
night visibility. Make sure the SMV sign is clean and
visible from the rear of the unit before transporting
the tractor and implement on a public roadway.
Replace the SMV emblem if faded, damaged, or no
longer reflective. OPS-U- 0020
Make sure that all tractor flashing warning lights,
headlights, and brake/tail lights are functioning
properly before proceeding onto public roads. While

MAINTENANCE
Before operating your Rotary Cutter, make sure it is properly lubricated and thoroughly inspected. Only a
minimum of time and effort is required to regularly lubricate and maintain this machine to provide long life and
trouble free operation.
Always disengage the PTO before raising the Rotary Cutter for transporting or making
adjustments.
Lubrication (Figure Mnt-0014)
Do not let excess grease collect on or around parts, particularly when operating in sandy areas. The
illustrations show lubrication points. The chart gives the frequency of lubrication in hours, based on normal
operating conditions. Severe or unusual conditions may require more frequent lubrication.
Use an SAE multi-purpose, lithium-type grease for
all locations shown. Be sure to clean the fitting
thoroughly before using grease gun.
Daily
lubrication of the driveline slip joint is necessary.
Failure to maintain proper lubrication will result in
damage to U-joints, gearbox, and/or driveshaft.

The Gearbox was filled with oil at the factory.
However, it is necessary that the operator check the
Gearbox before operations. The oil should be up
level of the Test Plug on the side of the Gearbox.
The Filler/Breather Plug is on the top of the
Gearbox. Fill through this Plug.
Check the oil level after operating long enough for
warmed oil to flow through the Bearings into the
lower Gearbox cavity. Refill to the test plug level.
Check the oil again before operation, after every 40
hours of mowing, and at the beginning and end of
each mowing season.
NOTE: Overfilling the Gearbox will cause pressure
to build up and cause Oil Seals to leak.
ATTENTION:
If the Gearbox suddenly starts
making an unusual noise, stop at once, check for
leaks, and refill Gearbox as required.
Recommended lubricant for GR60 is NLGI-000
(P/N 00765444) (Mnt-0001). Gearbox capacity is 4
Quarts.
Required lubricant for GR72 is a SAE 85W140T
(PN 00769031). Use gear lube with EP additives
for extreme pressure and temperature, with a AP:GI-5 Service rating. This lube also has tack agent
added so oil adheres to parts when box is not
running. (Mnt-0011). Gearbox capacity is 2 Quarts.
MAINTENANCE
Driveline Lubrication
MAINTENANCE
Grease Fittings are located on the Cross Assembly of each U-Joint and on the Round Housing. Grease the UJoint after each 8 hours of use. Do not force grease through the Needle Cup Assemblies. Grease the Round
Housing after every 8 hours of use, except in sandy soil conditions. Some PTO-to-Hitch connections may
necessitate cutting a hole in the shields to be able to align the Grease Fitting holes for lubrication.

Blade Servicing
Blade Sharpening
Always sharpen both blades at same time to
maintain balance.
Follow original sharpening
pattern as shown in Mnt-0008. Always sharpen
blades by grinding. DO NOT heat and pound out
edge. Do not sharpen blade to a razor edge, but
leave a 1/16" blunt edge. Do not sharpen back side
of blade.
Avoid personal injury. Always
block the cutter up to prevent if from falling when the blades and or carrier are being
serviced.
Replace bent or broken blades with new blades. NEVER ATTEMPT TO STRAIGHTEN,
WELD, OR WELD HARDFACING ON BLADES SINCE THIS WILL LIKELY CRACK OR
OTHERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLE SERIOUS INJURY
FROM THROWN BLADES. (SGM-10)
GR60/72 02/07
© 2007 Alamo Group Inc.
Maintenance Section 5-5
MAINTENANCE
Inspect blades before each use to determine that they are properly installed and in good condition. Replace
any blade that is bent, excessively nicked, worn, or has any other damage. Small nicks can be ground out
when sharpening.
When sharpening blades, grind each blade the same amount to maintain balance. The
difference in blade weights should not exceed 1 ounce. Unbalanced blades will cause
excessive vibration which can damage gear box bearings. Vibration may also cause
structural cracks in cutter housing.
Use only original equipment blades on this cutter. They are made of special heat-treated
alloy steel. Substitute blades may not meet specifications and may fail in a hazardous
manner that could cause injury.
MAINTENANCE
MAINTENANCE
Blade Removal
To remove blades for sharpening or replacement,
remove the cover plate on deck of cutter near gear
box. Remove lock nut from blade bolt. NOTE:
Inspect lock nut after removal and replace if threads
are damaged. Always replace nut when replacing
blade bolt. When installing blades be sure and
check blade bolt pivot diameter for wear. Replace
bolt if worn more than 1/4 inch at any point. Install
blade bolts with partially worn side of bolt either
toward or away from center. Tighten lock nut to 250
ft. lbs.
Avoid personal injury. Blade and/or blade carrier removal should be done only with the
tractor engine shut off, key removed, in neutral, parking brake on, and PTO disengaged and
the cutter blocked in the raised position.
Blade Carrier Removal
Remove cotter pin and loosen slotted nut on gearbox shaft. Loosen but do not remove the nut until the blade
carrier is loosened. Use a suitable 2 jaw gear puller to pull carrier off tapered gearbox shaft. If gear puller is
not available use long bar inserted through blade bolt access hole with end against rotor bar. Strike opposite
end of bar with sledge hammer. Rotate blade carrier 180 degrees and repeat process.
Blade Carrier Installation
Clean the hub on the blade carrier and the output shaft on the gearbox. Position carrier on the gearbox output
shaft and install hardened washer, slatted nut, and cotter pin.
Tighten nut holding blade carrier to minimum 450 ft. pounds, strike the carrier near the hub several times with a
heavy hammer to seat the hub. Use a suitable spacer over the nut to prevent damage to the nut and threads.
Retighten the nut to 450 ft. pounds. Install cotter pin and spread.
IMPORTANT: Always recheck gearbox output shaft slotted blade carrier retaining nut torque after a few hours
operation.
Avoid personal injury. Do not work under cutter without support blocks to keep frame from
falling.

Slip Clutch - GR60
Seasonal Slip Clutch Maintenance
It is important that the clutches slip when an
obstacle or load heavier than the 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 cutter use the following procedure
to make sure the clutch will slip and give the
overload protection required.
1.
Loosen nuts (Mnt-0017) on springs until the
springs are free, yet remain secure on bolts.
2.
Attach cutter to tractor and start the tractor.
Set the engine speed at 1200 RPM.
3.
Mark outer plates as shown in Mnt-0017.
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. (1) Tighten the nuts on the
coil spring clutch to their original position of
1-9/16" compressed spring length. (2) (Top
of washer to pressure plate)
GR60/72 02/07

Maintenance Section 5-7
MAINTENANCE
A slip clutch is incorporated in the PTO driveline. It is designed to slip, absorb the shock load, and protect the
driveline. There are two types of clutches furnished. (1) A clutch with 8 coil springs and (2) A clutch with a
single disc spring with 6 adjusting nuts.
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. (1)To adjust the coil spring slip clutch,
tighten the spring bolts 1/8 (maximum) turn at a time. Bolts should NEVER be adjusted to the point where the
coil springs are compressed solid. Minimum spring compression length is 1-15/32". (2) To adjust the disc
clutch, tighten the 6 bolts until they bottom out and then loosen each of them 2 turns.
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 rusted/corroded together. Should
this occur refer to the procedure described in the "Seasonal Clutch Maintenance" section on the next page.
MAINTENANCE
MAINTENANCE
Torque Limiter - GR72
Avoid overheating of the Torque Limiter by too long or too frequent slipping, as this can damage the friction
plates and limiter parts. When checking Torque Limiter for overheating, DO NOT touch with hand. Torque
Limiter could be extremely hot and cause severe burn.
If an adjustment is required, this may be done in the field by following the procedure outlined below. Following
these instructions will give maximum rated torque and long life. (See Mnt-0018).
1.
With the three Capscrews (#1) backed out until the points are below the surface of the circular Adjusting
Nut (#2), run Adjusting Nut up finger-tight, or slightly less than finger-tight.
2.
Alternately tighten the hardened, cup point Capscrews (#1) no more than one-half turn at a time until the
Capscrew heads "Bottom Out". Do not over tighten the Capscrews nor completely flatten the Spring
Washers (#3).
If the Hub is removed from the Shaft for any reason, the Shaft and Hub should be coated with a heavy grease
before reassembly to prevent Hub from freezing to Shaft.
Seasonal Torque Limiter Maintenance
It is important that the Torque Limiter slips when an obstacle or load heavier than the setting is encountered.
Before using the cutter each season, use the following procedure to make sure the torque limiter will slip and
give the overload protection required.
1.
Loosen Bolts (#1) until gap between adjusting nut (#2) and guide ring is approximately 1/16".
2.
Attach machine to tractor, set engine at approximately half throttle and quickly engage PTO. This
procedure will break Torque Limiter facings loose and allow the proper torque to be maintained.
3.
Return the bolts to their original position as described in (b) above.

Storage
Your rotary cutter represents an investment from which you should get the greatest possible benefit.
Therefore, when the season is over, the cutter should be thoroughly checked and prepared for storage so that
a minimum amount of work will be required to put it back into operation for the next season. The following are
suggested storage procedures:
1.
Thoroughly clean the cutter.
2.
Lubricate the cutter as covered in Maintenance Section.
3.
Tighten all bolts and pins to the recommended torque.
4.
Check the cutter for worn or damaged parts. Make replacements immediately.
5.
Store the cutter in a clean, dry place with the cutter housing resting on blocks.
6.
Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the
cutter.
Proper Torque For Fasteners
The chart lists the correct tightening torque for fasteners. When bolts are to be tightened or replaced, refer to
this chart to determine the grade of bolts and the proper torque except when specific torque values are
assigned in manual text.
Recommended Torque in Foot Pounds Unless Otherwise Stated in the Manual*
NOTE: These values apply to fasteners as received from supplier, dry or when lubricated with normal engine
oil. They do not apply if special graphited or molydisulphide greases or other extreme pressure lubricants are

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.

•
I have informed the Purchaser of this product of Warranty terms, provisions, and procedures that are applicable, reviewed the contents of the Operator’s Manual
including safety equipment, safe operation, and maintenance, reviewed the Safety Signs on implement (and tractor if possible), shown the AEM Mower Safety
Practices Video, and reviewed Purchaser’s responsibility to train his operators in safe operation.
• IMPLEMENTS: I have explained that Deflectors, Chain Guards, or Solid Skirts must be maintained in good repair and installed except in areas where persons,
vehicles, livestock, or other property will not be endangered by thrown objects and where such safety equipment would prevent the mower’s reasonable performance
of its assigned task.
• DRIVELINES: I have made certain that all driveline, gearbox, and other shields are in good repair and fastened securely in place to prevent injuries from
entanglement or thrown objects.
•
HYDRAULIC MACHINES: I have explained the necessity of using clean hydraulic oil, changing filters as instructed, stopping leaks, damage caused by
operating with over-heated oil, caring for hoses, using hoses of proper rating, the necessity of maintaining the specified operating pressure, and the potential hazard
of oil's penetrating the skin.
• BOOM-TYPE or FOLDING-TYPE IMPLEMENTS:
I have explained that it is not possible to guard against thrown objects when the head is lifted off ground
and that operator is responsible to watch out for persons in the area. I have explained that the lifted mower head or boom can contact overhead obstructions with
damage to cables and telephone lines and possible injury. I have explained that the extended head or boom or retracted boom can contact power lines with resulting
electrocution injury or death and that operator is responsible for keeping clear of such hazards.
Dealer’s Signature ___________________________________ Date ______________
I have been instructed on the paragraphs above, received and have been shown the AEM Mower Safety Practices Video and have been instructed in the contents
of the Operator’s Manual including safety signs, safety equipment, safe operation, maintenance, and the potential hazards of unauthorized alteration or modification
of the product. I have been informed of the warranty provisions and know that the warranty is not in effect until this form is received by Alamo Group.
I understand the Implement Guarding statements above and the potential hazards of operating without such guards. I understand that the operator is responsible for
the safety of others in the area. I have examined the product and accept it as being complete and in satisfactory condition with all required guards.
