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.
If you would like a VHS video tape of the video, please email AEMVideo@alamo-group.com or Fax

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.
SAFETY
READ, UNDERSTAND, and FOLLOW the following Safety Messages. Serious injury or
death may occur unless care is taken to follow the warnings and instructions stated in the
Safety Messages. Always use good common sense to avoid hazards.

Operator Safety Instructions and Practices
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.
“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.

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 too 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 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.

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)

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 gound level. Slipping
and falling can cause serious injury or death.
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.
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.
Avoid contact with hot surfaces of the engine or muffler. 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-38)
(SG-36)
Do not put hands or feet under mower decks. Blade Contact can result serious
injury or even death. Stay away until all motion has stopped and the decks are
securely blocked up.
(SGM-9)
Always keep a careful lookout and use extreme care when working around utility and municipal
obstructions. Never allow the Mower to contact any utility, municipal, or other type structure.
Clearly mark all mowing obstructions and consult local utility providers for a safe code of
operation.
(SPU-5)
Do not operate the implement while wearing loose fitting clothing. Entanglement of the clothin
with the rotating elements can result in serious injury or even death. Stay clear of all rotatin
elements at all times. (SSP-3)
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 AFrame. Lower the implement carefully to the ground. Do not put hands or feet under lifted
components.
(S3PT-1)
SAFETY
se extreme care when lowering or unfo
ng 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.
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)
SAFETY
e sure you have adequate knowledge of the property you w
e working on. Take time to make
yourself aware of any area underground lines or cables. Contact with buried lines or cable could
result in serious injury or death.
(SBH-6)
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)
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.
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 safe operation of the
tractor and Implement, and are physically large enough to reach and operate
the controls easily.
Do not mount the Tractor while the tractor is moving. Mount the Tractor only
when the Tractor and all moving parts are completely stopped.
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-11)
(SG-12)
(SG-13)
SAFETY
Do not operate this Equipment with hydraulic oil or fuel leaking. Oil and fuel are
expensive 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 tractor 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)
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.

Wait until all rotating motion has stop before dismounting. (SG-39)
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 movingtractor.
(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 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)
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.
reme 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.
any 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.
ow 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 0 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)
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.
Do not mow with two machines in the same area except with Cab tractors with the windows
closed.
(SGM-11)
(SGM-6)
(SGM-8)
SAFETY
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.
ower is designed for certain mowing applications and is rated to cut up to a spec
(SGM-12)
c 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 non-vegetative 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.
Do not operator or pull the mower into standing water. When uplift or fan type mower blades
contact water they can be severely deflected downward causing possible failure of blade
resulting in serious boldly injury to the operator or bystanders.
Use extreme caution when raising the Mower above ground level. Stop the Blades from
turning when the Mower is raised and passersby are within 100 yards. Raising the Mower
exposes the Cutting Blades which creates a potentially serious hazard and can cause serious
injury by objects thrown from the Blades or by contact with the Blades.
(SGM-15)
(SPU-1)
SAFETY
Rotary Mowers are capable under adverse conditions of throwing objects for
great distances (100 yards 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;
-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)
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
Do not turn so sharp or lift mower so high to produce a severe "knocking" of the Driveline which
will cause accelerated wear and breakage of drive train components and could result in possible
injury from the separated Driveline sections.
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.
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 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.
(SRM-4)
(SRM-7)
(S3PT-14)
SAFETY
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.

mportant 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)
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.
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 preven
loss of steering control which could result in property damage or possible injury. Do not transpor
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
SAFETY
operator or others to be injured or killed.
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.
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.
Transport only at safe speeds. Serious accidents and injuries can result from
operating this equipment at unsafe 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 safe 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 safe transport
speed for you and 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 that you have
determined are safe and which allow you to properly control the
equipment.
SAFETY
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. 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)
Be particularly careful when transporting the Implement using the tractor. Turn curves or go up or
down hills only at a low speed and at a gradual steering angle. Make certain that at least 20% of
the tractor’s weight is on the front wheels to maintain safe steerage. Slow down on rough or
uneven surfaces.

vegetation above the Mower’s rated capacity or to cut any type of non-vegetative 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.
Safe operation of the unit is the responsibility of a qualified operator. A qualified operator has read and
understands the implement and tractor Operator’s Manuals and is experienced in implement and tractor
operation and all associated safety practices. In addition to the safety messages contained in this manual,
safety decals are affixed to the implement and tractor. If any part of the operation and safe use of this
equipment is not completely understood, consult an authorized dealer for a complete explanation.
If the operator cannot read the manuals for themselves or does not completely understand the operation of the
equipment, it is the responsibility of the supervisor to read and explain the manuals, safety practices, and
operating instructions to the operator.
Safe operation of equipment requires that the operator wear approved Personal Protective Equipment (PPE)
for the job conditions when attaching, operating, servicing, and repairing the equipment. PPE is designed to
provide operator protection and includes the following safety wear:
PERSONAL PROTECTIVE EQUIPMENT (PPE)

•Close Fitting Clothing
•Respirator or Filter Mask (depends on mowing
conditions) OPS-U- 0002
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.
operator or others could result if the operator is under the influence of drugs or
alcohol.
The tractor used to operate the mower must have the power capacity to lift, pull, and operate the Power Take
Off (PTO) at the mower’s rated speed while traveling at a ground speed between 2 and 5 MPH. Operating the
mower with a tractor that does not meet the following requirements may cause tractor or mower damage and
be a potential danger to the operator and passersby.
Tractor Requirements and Capabilities
•ASAE approved Roll-Over Protective Structure (ROPS) or ROPS cab and seat belt.
-Drawbar ....................Extended 14” from PTO shaft end with safety chain attachment point
-Hydraulics................. Optional
•Front End Weight ............................. As needed to maintain 20% weight on front axle
•Power Take Off................................. 540 RPM 6-spline, 1-3/6” diameter output shaft
OPERATION
2.1 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.
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
2.3 Tractor Horsepower
The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing
conditions, the SE5 mower requires a tractor with at least 20 HP. Operating the mower with a tractor that does
not have adequate power may damage the tractor engine. Exceeding 50 HP may cause mower damage by
overpowering the unit in heavy cutting conditions.
OPERATION
2.4 3-Point Hitch
The tractor 3-point hitch must be rated to lift at least
730 lbs.
The SE6 mower is designed to be mounted on a
tractor with a CAT I 3-point hitch. Refer to the
tractor operator’s manual for the category of the
tractor being used. If the hitch does not conform to
ASAE CAT I dimensions, the mower may not fit or
raise properly. Consult an authorized dealer for
possible modification procedures to mount nonconforming hitches.
Depending on the hitch category, certain size pins
are used to attach the mower to the tractor. CAT I
hitches require 7/8” lower and 3/4” upper diameter
hitch pins.
CAT I Implement / Hitch Specification
Width from outside to outside A-frame.... 26 7/8”
Quick Hitch width inside lug to lug ......... 27 1/8”
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
2.6 Drawbar-Pull Type Mower
For equipment operating at 540 RPM, the tractor
drawbar must be positioned at a 14” distance from the
hitch point to the PTO shaft end for proper operation
and minimal wear to the driveline.
If attaching the mower tongue clevis to a 3-point hitch drawbar supported by the lower lift arms, the attaching
point must be extended past the main bar to allow for turning without binding the clevis and bar. Lift arm
stabilizers must be used with this type of drawbar to prevent the mower from swaying from side to side.
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.
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
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,
OPERATION
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.

3. 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.
