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

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

Safety Section 1-2
SAFETY
Engine Exhaust, some of its constituents, and certain vehicle components contain or emit
chemicals known to the state of California to cause cancer and birth defects or other
reproductive harm. (SG-30)
Battery posts, terminals and related accessories contain lead and lead compounds,
chemicals known to the state of California to cause cancer, birth defects or other
reproductive harm. (SG-31)
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. (S3PT-10)
“Wait a minute...Save a life!”
Never crawl under a raised Implement supported solely by the Tractor 3-Point hitch.
Release of the control lever or mechanical failure will result in the Implement falling and
possible injury or death. Always securely block up the Implement before crawling
underneath to perform repairs and service. (S3PT-19)
Never operate the Tractor or Implement until you have read and
completely understand this Manual, the Tractor Operator’s Manual, and
each of the Safety Messages found in the Manual or on the Tractor and
Implement. Learn how to stop the tractor engine suddenly in an
emergency.
Never allow inexperienced or untrained personnel to
operate the Tractor and Implement without supervision. Make sure the
operator has fully read and understood the manuals prior to operation.
(SG-4)
The operator and all support personnel should wear hard hats, safety
shoes, safety glasses, and proper hearing protection at all times for
protection from injury including injury from items that may be thrown by
the equipment. (SG-16)

Safety Section 1-3
SAFETY
For your protection while operating or servicing equipment, wear relatively tight and belted
clothing to avoid entanglement in moving parts. Tie up and protect long hair that could
become entangled in machinery. Remove all jewelry including necklaces, rings and
watches which can get caught in machinery or on corners or edges of the equipment.
Serious injury can result from entanglement with the machinery. (SG-42)
SAFETY
SAFETY
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)
Always read carefully and comply fully with the manufacturer’s
instructions when handling oil, solvents, cleansers, and any other
chemical agent. (SG-22)
KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement
and possible serious injury or death. (SG-24)
Never allow children to play on or around Tractor or Implement. Children can slip or fall off
the Equipment and be injured or killed. Children can cause the Implement to shift or fall
crushing themselves or others. (SG-25)
NEVER use drugs or alcohol immediately before or while operating the
Tractor and Implement.
Drugs and alcohol will affect an operator’s
alertness and coordination and therefore affect the operator’s ability to
operate the equipment safely.
Before operating the Tractor or
Implement, an operator on prescription or over-the-counter medication
must consult a medical professional regarding any side effects of the
medication that would hinder their ability to operate the Equipment safely.
NEVER knowingly allow anyone to operate this equipment when their
alertness or coordination is impaired. Serious injury or death to the
operator or others could result if the operator is under the influence of
drugs or alcohol. (SG-27)
Prolonged operation may cause operator boredom and fatigue affecting safe operation.
Take scheduled work breaks to help prevent these potentially impaired operating
conditions. Never operate the Implement and Tractor in a fatigued or bored mental state
which impairs proper and safe operation. (SG-32)

Safety Section 1-4
SAFETY
Use extreme caution when getting onto the Implement to perform repairs, maintenance and
when removing accumulated material. Only stand on solid flat surfaces to ensure good
footing. Use a ladder or raised stand to access high spots which cannot be reached from
ground level. Slipping and falling can cause serious injury or death. (SG-33)
Avoid contact with hot surfaces including hydraulic oil tanks, pumps, motors, valves and
hose connections. Relieve hydraulic pressure before performing maintenance or repairs.
Use gloves and eye protection when servicing hot components. Contact with a hot surface
or fluid can cause serious injury from burns or scalding. (SG-34)
(SG-36)
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)
Do not put hands or feet under mower decks. Blade Contact can result
in serious injury or even death. Stay away until all motion has stopped
and the decks are securely blocked up. (SGM-09)
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
clothing with the rotating elements can result in serious injury or even death. Stay clear of
all rotating elements at all times. (SSP-03)

Safety Section 1-5
SAFETY
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.
SAFETY
SAFETY
Repeated or substantial breathing of hazardous dusts, including
crystalline silica, could cause fatal or serious respiratory disease including
silicosis. Concrete, masonry, many types of rock, and various other
materials contain silica sand. California lists respirable crystalline silica as
a substance known to cause cancer. Operation of this equipment under
certain conditions may generate airborne dust particles that could contain
crystalline silica. In those conditions, personal protective equipment
including an appropriate respirator must be used. If excessive dust is
generated, a dust collection or suppression system should also be used
during operation. (SG-41)
Equipment Operation Safety Instructions and Practices
Never leave the Tractor and Implement unattended while the Implement is in the lifted
position. Accidental operation of lifting lever or a hydraulic failure may cause sudden drop
of unit with injury or death by crushing. To properly park the implement when disconnecting
it from the tractor, lower the stand and put the retaining pin securely in place, or put a secure
support under the A-Frame. Lower the implement carefully to the ground. Do not put hands
or feet under lifted components. (S3PT-1)
Use extreme care when lowering or unfolding the implement’s wings. Make sure no
bystanders are close by or underneath the wings. Allow ample clearance around the
implement when folding or unfolding the wings. Use extreme caution around buildings or
overhead power lines. (S3PT-05)
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)
Be sure you have adequate knowledge of the property you will be 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. If in doubt about buried utility lines call 811
before digging or 1-800-258-0808. (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)

Safety Section 1-6
SAFETY
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)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
Never allow children to operate, ride on, or come close to the Tractor or
Implement. Usually, 16-17 year-old children who are mature and
responsible can operate the implement with adult supervision, if they
have read and understand the Operator’s Manuals, been trained in
proper operation of the tractor and Implement, and are physically large
enough to reach and operate the controls easily. (SG-11)
Do not mount or dismount the Tractor while the tractor is moving. Mount
the Tractor only when the Tractor and all moving parts are completely
stopped. (SG-12)
Start tractor only when properly seated in the Tractor seat. Starting a
tractor in gear can result in injury or death. Read the Tractor operators
manual for proper starting instructions. (SG-13)
Eagle 20 03/09

Safety Section 1-7
SAFETY
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)
SAFETY
SAFETY
Do not operate this Equipment with hydraulic oil or fuel leaking. Oil
and fuel are explosive and their presence could present a hazard. Do
not check for leaks with your hand! High-pressure oil streams from
breaks in the line could penetrate the skin and cause tissue damage
including gangrene. To check for a hose leak, SHUT the unit ENGINE
OFF and remove all hydraulic pressure. Wear oil impenetrable gloves,
safety glasses and use Cardboard to check for evidence of oil leaks. If
you suspect a leak, REMOVE the HOSE and have it tested at a Dealer.
If oil does penetrate the skin, have the injury treated immediately by a
physician knowledgeable and skilled in this procedure. (SG-15)
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health. (SG-23)
Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause
Implement driveline or blade failures resulting in serious injury or death. (SG-26)
Operate the Tractor and/or Implement controls only while properly seated in the Tractor seat
with the seat belt securely fastened around you. Inadvertent movement of the Tractor or
Implement may cause serious injury or death. (SG-29)
In case of mechanical difficulty during operation, place the transmission in the park
position, set the parking brake, shut down all power, including the PTO and the engine and
remove the key. Wait until all rotating motion has stopped before dismounting. (SG-39)
Do Not operate this equipment in areas where insects such as bees may attack you and/or
cause you to lose control of the equipment. If you must enter in such areas, use a tractor
with an enclosed Cab and close the windows to prevent insects from entering. If a tractor
cab is not available, wear suitable clothing including head, face, and hand protection to
shield you from the insects. Attacking insects can cause you to lose control of the tractor,
which can result in serious injury or death to you or bystanders. Never dismount a moving
tractor. (SG-40)
Mow only in conditions where you have clear visibility in daylight or with adequate artificial
lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least
100 yards(90 m) in front and to the sides of the tractor and mower. Make sure that you can
clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions,
power lines, debris and foreign objects. If you are unable to clearly see these type of items
discontinue mowing. (SGM-1)

Safety Section 1-8
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-02)
Extreme care should be taken when operating near loose objects such
as gravel, rocks, wire, and other debris. Inspect the area before
mowing. Foreign objects should be removed from the site to prevent
machine damage and/or bodily injury or even death. Any objects that
cannot be removed must be clearly marked and carefully avoided by the
operator. Stop mowing immediately if blades strike a foreign object.
Repair all damage and make certain rotor or blade carrier is balanced
before resuming mowing. (SGM-05)
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the
operating parts of the mower head. These items could then swing outside the housing at
greater velocities than the blades. Such a situation is extremely hazardous and could result
in serious injury or even death. Inspect the cutting area for such objects before mowing.
Remove any like object from the site. Never allow the cutting blades to contact such items.
(SGM-06)
Mow at the speed that you can safely operate and control the tractor and mower. The
correct mowing speed depends on terrain condition and grass type, density, and height of
cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds
when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power
lines, or when debris and foreign objects are to be avoided. (SGM-07)
Avoid mowing in reverse direction when possible. Check to make sure there are no
persons behind the mower and use extreme care when mowing in reverse. Mow only at a
slow ground speed where you can safely operate and control the tractor and mower.
Never mow an area that you have not inspected and removed debris or foreign material.
(SGM-08)
Do not mow with two machines in the same area except with Cab tractors with the windows
closed. (SGM-11)

Safety Section 1-9
SAFETY
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)
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.
SAFETY
-Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating.
-Never allow clippings or debris to collect near drivelines, slip clutches, and gearboxes.
Periodically shut down the Tractor and Mower and clean clippings and collected debris from
the mower deck. (SGM-12)
The Mower is designed for certain mowing applications and is rated to cut up to a specific
size vegetation (see Mower Standard Equipment and Specifications). DO NOT use this
mower to cut vegetation above the Mower’s rated capacity or to cut any type of nonvegetative material. Only operate this Mower on a properly sized and equipped Tractor.
Operating this Mower in an application for which it is not designed and/or operating the
Mower with the wrong size Tractor can cause Mower component damage and equipment
failure resulting in possible serious injury or death. (SGM-14)
Do not operate 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. (SGM-15)
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. (SPU-1)

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;
-Passersby are outside the existing thrown-object zone;
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, reduce streaking, and
make the final cut more uniform). (SRM-01)
Do Not attempt to raise or lower the implement wing unless the Implement tongue is
securely attached to the Tractor drawbar. The Implement could tip over and cause
equipment damage and possible serious injury or death. Raise or Lower the mower wing
only while seated in the Tractor operator’s seat with the seat belt securely fastened. (SRM-2)
Do not 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. (SRM-04)
Do not let the Blades turn when the Mower Deck is raised for any
reason, including clearance or for turning. Raising the Mower deck
exposes the Cutting Blades which creates a potentially serious hazard
and could cause serious injury or even death from objects thrown from
the Blades. (SRM-07)
DO NOT allow any person under a folded wing unless wing is securely
locked up or supported. DO NOT approach the Implement unless the
Tractor is turned off and all motion has ceased. Never work under the
frame work, or any lifted component unless the implement is securely
supported or blocked up. A sudden or inadvertent fall by any of these
components could cause serious injury or even death. (STI-03)

SAFETY
Connecting or Disconnecting Implement Safety Instructions and
Practices
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
PTO. Use of an adapter can double the operating speed of the Implement resulting in
excessive vibration, thrown objects, and blade and implement failure. Adapter use will also
change the working length of the driveline exposing unshielded driveline areas. Serious
bodily injury and/or equipment failure can result from using a PTO adapter. Consult an
authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.
SAFETY
(S3PT-14)
Always shut the Tractor completely down, place the transmission in park, and set the
parking brake before you or anyone else attempts to connect or disconnect the Implement
and Tractor hitches. (S3PT-15)
When attaching the Implement input driveline to the Tractor PTO, it is important that the
connecting yoke spring activated locking collar slides freely and the locking balls are seated
securely in the groove on the Tractor PTO shaft. Push and pull the driveline back and forth
several times to ensure it is securely attached. A driveline not attached correctly to the
Tractor PTO shaft could come loose and result in personal injury and damage to the
Implement. (S3PT-17)
Before operating the Implement, check to make sure the Implement input driveline will not
bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates
the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out
can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and
through the support bearings or downward onto the PTO shaft, breaking it off. A broken
driveline can cause personal injury. (S3PT-18)
Never unhitch without using the Tongue Jack. The Tongue is very heavy. Attempting to lift
the Tongue without using the Tongue Jack could cause strains or other injury. Allowing the
tongue to fall suddenly and unexpectedly could result in crushing injury. Use the Tongue
Jack for lifting the Implement only. Overloading the Tongue Jack can cause failure with
possible serious bodily injury or even death. (STI-04)
On a fully-assembled unit, do not remove the Wing Retaining Strap until hoses are attached
to the tractor and the Wing Cylinders are filled with oil. Lower the Wings slowly and
carefully. Keep bystanders away during operations. (STI-05)

SAFETY
Transporting Safety Instructions and Practices
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.
Allow sufficient clearance for the Implement to swing outward while turning. Implements
carried behind the Tractor will swing outside the tire path when making turns. Contacting a
solid object while turning will cause equipment damage and possible injury. (S3PT-20)
Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in
such a way as to be clearly visible and legible. When transporting the
Equipment use the Tractor flashing warning lights and follow all local
traffic regulations. (SG-6)

SAFETY
(S3PT-02)
SAFETY
Transport only at speeds where you can maintain control of the
equipment. Serious accidents and injuries can result from operating this
equipment at high speeds. Understand the Tractor and Implement and
how it handles before transporting on streets and highways. Make sure the Tractor steering
and brakes are in good condition and operate properly.
SAFETY
Before transporting the Tractor and Implement, determine the proper transport speeds for
you and the equipment. Make sure you abide by the following rules:
Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes smoothly
to determine the stopping characteristics of the Tractor and Implement. As you increase
the speed of the Tractor the stopping distance increases.
Determine the maximum
transport speed not to exceed 20 mph (30 kph) for transporting this equipment.
Test the equipment at a slow speed in turns. Increase the speed through the turn only after
you determine that the equipment can be operated at a higher speed. Use extreme care
and reduce your speed when turning sharply to prevent the tractor and implement from
turning over. Determine the maximum turning speed for you and this equipment before
operating on roads or uneven ground.
Only transport the Tractor and Implement at the speeds which allow you to properly control
the equipment.
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes
or worn tires. When operating down a hill or on wet or rain slick roads, the braking distance
increases: use extreme care and reduce your speed. When operating in traffic always use
the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you
and watch out for the other guy. (SG-19)
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. (STI-01)
When the Wings are folded for transport, the center of gravity is raised and the possibility of
overturn is increased. Drive slowly and use extreme caution when turning on hillsides.
Overturning the Implement could cause the Implement to overturn the Tractor and vice
versa resulting in serious injury or even death. Never fold wings on a hillside...the
Implement may overturn. (STI-02)
Only tow the Implement behind a properly sized and equipped Tractor
which exceeds the weight of the Implement by at least 20%. DO NOT
tow the Implement behind a truck or other type of vehicle. Never tow the
Implement and another Implement connected in tandem. Never tow the
Implement at speeds over 20 MPH. (STI-06)

Safety Section 1-14
SAFETY
Secure the Implement for transport before traveling on public roads. For pull-type
Implements, secure the center axle using cylinder stops or transport pin and properly attach
a safety chain between the Implement and Tractor. Secure wings in upright position on
folding Implements using wing transport locks. (STI-7)
Always keep a careful lookout and use extreme care when working
around overhead obstructions and electrical power lines.
The
Implement wing can be over 10 feet high. Never allow the Implement
wing to come within 10 feet of any power line. (STI-8)
Maintenance and Service Safety Instructions and Practices
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)
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-09)
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)
Never interfere with factory-set hydraulic calibrations. Any change in calibration could
cause a failure of the equipment and may result in injury. (SBH-13)
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)

SAFETY
Your driving vision may be reduced or impaired by the tractor, cab, or implement. Before
driving on public roadways identify any limited vision areas, and make adjustments to your
operating position, mirrors, and the implement transport position so that you can clearly
see the area where you will be traveling, and any traffic that may approach you. Failure to
maintain adequate vision of the public roadway and traffic can result in serious injury or
even death. (STI-10)
SAFETY
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)
SAFETY
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)
Never attempt to lubricate, adjust, or remove material from the Implement while it is in
motion or while tractor engine is running. (SG-20)
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)
Perform service, repairs and lubrication according to the maintenance section. Ensure the
unit is properly lubricated as specified in the lubrication schedule and all bolts and nuts are
properly torqued. Failure to properly service, repair and maintain this Implement in good
operating condition could cause component failure and possible serious injury or even
death. (SG-35)
Use caution and wear protective gloves when handling sharp objects such as blades,
knives, and other cutting edges. Be alert to worn component surfaces which have sharp
edges. Sharp surfaces can inflict severe laceration injuries if proper hand protection is not
worn. (SG-37)
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)

INTRODUCTION
This Rotary Mower is designed with care and built with quality materials by skilled workers. Proper assembly,
maintenance, and operating practices, as described in this manual, will help the owner/operator get years of
satisfactory service from the machine.
INTRODUCTION
The purpose of this manual is to familiarize, instruct, and train. The Assembly Section instructs the owner/
operator in the correct assembly of the Mower using standard and optional equipment.
Careful use and timely service save extensive repairs and costly downtime losses. The Operation and
Maintenance Sections of the manual train the owner/operator how to work the Mower correctly and attend to
appropriate maintenance. The Trouble Shooting Guide helps diagnose difficulties with mower and offers
solution 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.
Alamo Industrial typically offers three types of shielding to protect the operator, passerby, livestock, and
property from thrown objects... deflectors, single chain guards, and double chainguards. Shielding should be
selected based on the intended use of the mower. Double chainguards or deflectors should be used for
highway, right-of-way, parks or greenbelt mowing or all other mowing where human dwellings, vehicles, or
livestock could be within 300 feet of the mower. Chainguards are more durable, provide a longer service life
and require less maintenance and replacement than deflectors. Single chainguards may be sufficient for
agriculture and other mower use only where passersby or property are not within 300 feet of the mower during
operation.
No shielding is 100% effective in preventing thrown objects. The possibility of injury and property damage from
this hazard can be substantially reduce by selecting proper shielding, maintaining the mower and shielding in
good operational condition, inspecting the area for foreign debris before mowing, operating the mower at a
minimum cutting height of 4”, and keeping persons at a minimum distance of 300 feet from the mower at all
times during operation.

OPERATION
2.2 Tractor Safety Devices
If transporting or operating the tractor and implement near a public roadway, the tractor must be equipped with
proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of
the unit. Lights and a SMV emblem must be equipped directly on implements if the visibility of the tractor
warning signals are obscured.
OPERATION
Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were
removed for access to connect, service, or repair the tractor or implement. Never operate the tractor PTO
with the PTO master shield missing or in the raised position. OPS-U- 0004
2.3 Tractor Horsepower
The horsepower required to operate the mower depends on several operating factors including the vegetation
to be cut, terrain condition, operator experience, condition of the mower and tractor, and others. For most
mowing conditions, the Eagle 20 and Eagle 14 mower requires a tractor with a minimum of 75 HP. Operating
the mower with a tractor that does not have adequate power may damage the tractor engine.
2.4 Drawbar
The tractor drawbar must be positioned at a certain
length based on the operating speed of the mower
for proper driveline operation. If the mower is a 540
RPM unit, position the drawbar length from shaft end
to hitch hole at 14”. For 1000 RPM mowers, set the
drawbar length at 16” for 21 spline 1-3/8” mowers
and at 20” for 1-3/4” 20 spline mowers.
Ensure that the drawbar is rated to carry the tongue
weight of the mower.
Pintle Hook Hitch-Optional Equipment
Drawbar length must be modified to
dimension “A” (CV Driveline = 17” ± 2”)

obtain
Operation Section 4-6
OPERATION
2.5 Tractor Hydraulics
The mower center section and each wing are positioned with hydraulic cylinders that are operated by the
tractor hydraulic pump. The tractor must have a minimum of 2 hydraulic control valves devoted to the mower
unless the tractor is fitted with a 3-spool control valve (extra equipment).
2.6 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
2.7 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: 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_A
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
PTO. Use of an adapter can double the operating speed of the Implement resulting in
excessive vibration, thrown objects, and blade and implement failure. Adapter use will also
change the working length of the driveline exposing unshielded driveline areas. Serious
bodily injury and/or equipment failure can result from using a PTO adapter. Consult an
authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.
(S3PT-14)
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)
Eagle 20 03/09

Operation Section 4-7
OPERATION
A 3-spool control valve is required if the tractor is equipped with a single valve and is recommended for those
with two valves so that the center section and each wing can be controlled independent of one another. Refer
to the Assembly Section of this manual for properly equipping the tractor with a 3-spool control valve. Tractors
equipped with three hydraulic ports can position the center section and each wing independently with no extra
equipment. If the tractor is equipped with only two hydraulic ports and a 3-spool control valve is not used, the
wings cannot be operated independently and will raise and lower at different speeds.
OPERATION
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
OPERATION
Do not mount or dismount the Tractor while the tractor is moving. Mount
the Tractor only when the Tractor and all moving parts are completely
stopped. (SG-12)
3.1 Boarding the Tractor
Use both hands and equipped handrails and steps for support when boarding the tractor. Never use control
levers for support when mounting the tractor. Seat yourself in the operator’s seat and secure the seat belt
around you.
Never allow passengers to ride on the tractor or attached equipment. Riders can easily fall off and be
seriously injured or killed from falling off and being ran over. It is the operator’s responsibility to forbid all extra
riders at all times. OPS-U- 0008
Never allow children to operate, ride on, or come close to the Tractor or
Implement. Usually, 16-17 year-old children who are mature and
responsible can operate the implement with adult supervision, if they
have read and understand the Operator’s Manuals, been trained in
proper operation of the tractor and Implement, and are physically large
enough to reach and operate the controls easily. (SG-11)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
3.2 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)
4. STARTING THE TRACTOR
Essential Tractor Controls:
• Locate the light control lever.
• Locate the engine shut off control.
• Locate the brake pedals and the clutch.
• Locate the PTO control.
• Locate the 3-point hitch control lever.
• Locate the hydraulic remote control levers.
Before starting the tractor ensure the following:
• 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.
After the tractor engine is running, avoid accidental contact with the tractor transmission to prevent sudden
and unexpected tractor movement. OPS-U-0028
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)

tractor controls before starting the tractor. Review the tractor operator’s manual and consult an authorized
dealer for tractor operation instructions if needed.
OPERATION
5. 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
OPERATION
Always shut the Tractor completely down, place the transmission in park, and set the
parking brake before you or anyone else attempts to connect or disconnect the Implement
and Tractor hitches. (S3PT-15)
5.1 Connecting the Mower Tongue to the Tractor
1. Ensure the tractor is equipped with the correct
PTO shaft and the drawbar is set at the correct
length.
2. Using the parking jack, position the tongue clevis
to the height of the tractor drawbar. Adjust the
mower tongue clevis to be level and parallel with
the tractor drawbar using the control rod connecting the mower tongue clevis to the deck.
3. Board the tractor and start the engine. Back the
tractor to the mower aligning the drawbar hitch
hole with the mower tongue clevis. Turn off the
tractor engine, place the tractor in park, and set
the parking brake before dismounting.
4. To attach the mower, place two 1” flatwashers (1)
positioned under top lip of tongue clevis and to
the top of drawbar. Add additional 1” flatwashers (2) between the bottom of drawbar and bottom lip of clevis to fill open space. Insert a 1”
diameter grade 5 or 8 bolt (3) through clevis and
drawbar and retain in position with a 1” locknut
(4). Tighten the locknut securely but do not overtighten which could spring or break the clevis.
NEVER attach mower to the tractor with a pin not
having a nut.
5. Securely attach the mower safety chain to the
tractor drawbar or drawbar support frame.
6. Lower the jack until the tongue is completely
supported by the drawbar. Remove jack from the
tongue and place on storage bracket of mower.
Eagle 20 03/09

Operation Section 4-10
OPERATION
Safety Tow Chain
If the mower is towed on a public roadway, a safety chain with tensile strength equal to or greater than the
gross weight of the mower must be connected between the tractor and mower. This will help control the
implement in the event the tongue becomes disconnected from the drawbar. Make sure the chain is attached
to a secure location on the tractor and not to an intermediate support.
5.2 Connecting Mower Hydraulic Lines to the Tractor
With the tractor shut down and secured in position, relieve hydraulic pressure from the tractor by moving the
control levers back and forth several times or placing the levers in the float position.
When connecting the mower hydraulic lines, keep hoses, quick couplers, and swivels free of contamination.
Never leave a disconnected hose end open and cap the tractor hydraulic outlet ports when not in use. If the
tractor ports or mower hydraulic hose ends become contaminated, wipe clean with a rag before connecting.
Operating Mower Hydraulics with Three Tractor Hydraulic Ports
Connect one hose into each hydraulic port. Connect lines to correspond with position of hydraulic control
levers.
Operating Mower Hydraulics with Two Tractor Hydraulic Ports
The lines that operate the wings must be plumbed together and will be controlled using one hydraulic control
valve and the center section with the remaining control valve. Ensure that the operator is aware that each wing
cannot be controlled independently nor will they raise and lower simultaneously.
Operating the Mower Hydraulics with a 3-Spool Hydraulic Control Valve (Extra Equipment)
Ensure the valve matches the hydraulic operating system of the tractor (open or closed center). Refer to the
Assembly Section for additional information on equipping the tractor with a 3-spool control valve.
Mount the valve bank to a tractor fender or other accessible location. Connect valve bank inlet and outlet lines
to outlets of the same tractor hydraulic port. Connect the mower hydraulics to the control valve bank with the
center section line to the right port. Connect the wing cylinder lines to the control valve positioned to
correspond with the left and right wing.
Eagle 20 03/09
© 2009 Alamo Group Inc.
Operation Section 4-11
OPERATION
After connecting both ends of the safety chain, drive the tractor to the right and left to check for proper chain
length. Adjust length as necessary and allow only enough slack in the chain to make a maximum turn in both
directions. When not in use, store the safety chain to protect it from mud or standing water by wrapping the
chain around the tongue. Replace the safety chain if one ore more links or end fittings are broken, stretched or
otherwise damaged or deformed. OPS-U-0039
OPERATION
OPERATION
To activate the 3-spool hydraulic control valve, tie the tractor’s hydraulic control lever back to keep hydraulic oil
continuously fed to the valve bank.
Hydraulic Line Support
After connecting the mower hydraulic lines to the tractor, support the hoses with the equipped brackets.
Ensure that hoses do not contact the driveline, do not bind while turning, and do not become pinched or
kinked.
Hydraulic Cylinder Priming
Hydraulic Cylinders must be filled with hydraulic oil before removing the wing transport braces to lower the
mower wings. Hydraulic cylinders and lines are filled by holding the valve control levers in the raised position
until the cylinders fully retract (wing cylinders) and extend (center cylinder). Place control levers in the float
position and repeat process a second time. Ensure wings are entirely supported by the cylinders before
removing the transport braces. NEVER drive out bar pins and NEVER remove braces that have tension on
them.
6. 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
Never work under the Implement, the framework, or any lifted
component unless the Implement is securely supported or blocked up
to prevent sudden or inadvertent falling which could cause serious
injury or even death. (SG-14)

OPERATION
6.1 Setting Deck Height
LEVELING DECK CENTER SECTION
1. Place the tractor and mower on a level surface
and lower both wings.
3. Shut down the tractor, place the transmission
in park, and set the parking brake before
dismounting.
4. Level the mower deck front to rear by
adjusting the leveling rods linking the tongue
to the rear axle. DO NOT allow feet or other body part underneath the mower when making adjustments.
To adjust rod length, loosen jamnut and screw turnbuckles. To lower the front, lengthen the rods and to
raise the front, shorten the rods. DO NOT unscrew turnbuckles to the point that either rod threaded ends
becomes disconnected which will cause the mower to fall. Re-tighten jamnuts when deck is leveled.
Alternate adjustments between rods and adjust at equal lengths to maintain equal tension.
Improper adjustments may cause rods to snap or bend.
5. Place split collar assemblies on the center axle hydraulic cylinder rod to maintain a set cutting height each
time the mower is raised and lowered.
LEVELING WING SECTIONS WITH CENTER
To level the wing sections with the deck center,
adjust the leveling screw between the wing axle
and the center axle. To lower the wing, loosen the
jamnut and shorten the screw assembly, lengthen
the screw assembly to raise the wing. After wings
are leveled, retighten jamnuts to maintain settings.
Eagle 20 03/09

Operation Section 4-13
OPERATION
2. Use the center section hydraulic cylinder to
set the mower at approximately 3/4” above the
desired cutting height. The additional height is
necessary so that after the mower has been
leveled, the deck pitch can be set such that
the front of the mower is slightly lower than the
rear.
OPERATION
6.2 Setting Deck Pitch
OPERATION
To facilitate safe and efficient operation, the mower
should be operated with the deck approximately
3/4” LOWER IN THE FRONT THAN THE REAR.
Operating the mower at this pitch will allow 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 deck pitch.
Adjust the leveling rods linking the tongue to the
rear axle until the front of the mower is at least 3/4”
lower in the front that than the rear. To lower the
front, lengthen the leveling rods and to raise the
front shorten the leveling rods. IMPORTANT:
Adjust the leveling rods the same amount and
maintain equal tension in the rods. Improper adjustment may cause rods to snap or bend. Retighten the
jamnuts after the deck pitch has been set. OPS-R-0002
6.3 Lowest Cutting Height
NOTE: Only operate in the lower position when you
are mowing in an agricultural application, be sure
there are no bystanders, passerby or livestock with
in 300 feet. .
To achieve the lowest possible cutting height, raise
the side skirt from the upper set of holes to the
lower set of holes shown in Figure Op-245
Never crawl under a raised Implement supported solely by the Tractor 3-Point hitch.
Release of the control lever or mechanical failure will result in the Implement falling and
possible injury or death. Always securely block up the Implement before crawling
underneath to perform repairs and service. (S3PT-19)

Operation Section 4-14
OPERATION
Also raise both skid shoes from the lower holes to
the upper holes as shown in Figure Op-246.
NOTE: Change height back to normal position
before operating or mowing on roadside, ditches
or greenbelts
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, reduce streaking, and
make the final cut more uniform). (SRM-01)

OPERATION
7. DRIVELINE ATTACHMENT
OPERATION
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. Push and pull the driveline back and forth
several times to ensure it is securely attached. A driveline not attached correctly to the
Tractor PTO shaft could come loose and result in personal injury and damage to the
Implement. (S3PT-17)
7.1 Driveline Length Check
Before operating the Implement, check to make sure the Implement input driveline will not
bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates
the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out
can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and
through the support bearings or downward onto the PTO shaft, breaking it off. A broken
driveline can cause personal injury. (S3PT-18)
When fitting the mower to the tractor , the telescoping driveline must be inspected to ensure that at its most
compressed position, the shafts do not “bottom out”, and when at its farthest extended postion, there is
sufficient engagement between the profiles to operate safely. At its shortest length, there must be at least at 1”
clearance between each profile end and opposite profile universal joint. At its farthest operating extension, a
minimum profile engagement of 5-1/2” must be maintained.
Eagle 20 03/09

Operation Section 4-16
OPERATION
“Bottoming Out” Check Procedure
•
•
•
•
Engagement Check Procedure
•
With the driveline attached, position the mower to the point where the telescoping driveline is at its maximum
extension. Completely shut down the tractor and secure in position.
•
Mark the inner driveline shield 1/8” from the end of the outer shield.
•
Disconnect the driveline from the tractor and separate the two driveline halves.
•
Measure the distance from the mark to the end of the inner profile. This length is the amount the driveline profiles were
engaged.
•
If the engaged length is less than 6”, the shaft is considered too short and should be replaced with a longer shaft.
Consult an authorized dealer to purchase the required driveline length.
NOTE: If the driveline cannot be shortened and still maintain the required profile engagement, the operator must be made
aware of terrain conditions and avoid situations which pose a potential problem to avoid damaging the driveline or move
drawbar to 16” or 20” position for required clearance. OPS-R-0005_O
Eagle 20 03/09

Operation Section 4-17
OPERATION
•
Disconnect driveline from the tractor and slide
the profiles together until fully compressed.
Place a mark on the inner shield 1/8” from the
end of the outer shield.
Reattach the driveline to the PTO Shaft.
Lift Type - With the PTO NOT TURNING, raise
and lower the mower and watch shaft movement.
Pull Type - With the PTO NOT TURNING, drive
the tractor and mower through the sharpest turn
possible and watch shaft movement. With the
PTO NOT TURNING, drive the tractor and
mower through the most severe terrain conditions expected and watch shaft movement.
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, contact your local dealer or tech service for proper directions. OPS-R-0004_B
OPERATION
7.2 Constant Velocity (CV) Driveline
For mowers equipped with a Constant Velocity (CV) driveline, the maximum turning angle between the tractor
and mower must be determined to ensure the joint angle does not over-extend which can cause CV joint
damage. Constant Velocity joints enable the driveline to operate smoothly with no vibrations and clattering at
angles up to 70°. Angles greater than 80° can result in mechanical damage to the CV joint and mower
driveline.
OPERATION
The Constant Velocity joint must be lubricated every 8 hours of operation as specified in the Maintenance
Section. Failure to properly lubricate the joint will result in accelerated wear and joint component failure.
CV Driveline Maximum Angle Check Procedure
With the mower attached to the tractor and the driveline disconnected from the tractor PTO stub make a
hard left turn until there is approximately a 1" clearance between the left rear tractor tire and mower frame or
tongue.
Stop and completely shut down the tractor. Place the tractor in Park and apply the Parking Brake before
dismounting.
Check the CV joint at this maximum turning radius by holding the driveline yoke above the PTO shaft and then
angle the CV joint to its maximum angle. A minimum difference of 10 degrees between the center line of the
yoke and the PTO shaft must be maintained to ensure the joint will not be over angled. If the joint cannot be
angled at least 10°, there is a potential problem of over-angling the joint while making sharp turns.
Solutions: To ensure the joint is not damaged, check the following:
Check the drawbar length to ensure that it is at the proper length for the RPM speed of the mower.
Move the tractor rear tires wider apart to limit the tractor turning radius.
Position the mower at multiple angles and perform the above procedure. Determine the sharpest turning
radius that maintains a safe operating angle and note this position to the operator. OPS-R-0006
Eagle 20 03/09

Operation Section 4-18
OPERATION
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. (SRM-04)
8. PRE-OPERATION INSPECTION AND SERVICE
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)
DO NOT allow any person under a folded wing unless wing is securely
locked up or supported. DO NOT approach the Implement unless the
Tractor is turned off and all motion has ceased. Never work under the
frame work, or any lifted component unless the implement is securely
supported or blocked up. A sudden or inadvertent fall by any of these
components could cause serious injury or even death. (STI-03)
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)

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

Operation Section 4-29
OPERATION
This Implement is wider than the Tractor. Be careful when operating or transporting this
equipment to prevent the Implement from running into or striking sign posts, guard rails,
concrete abutments or other solid objects. Such an impact could cause the Implement and
Tractor to pivot violently resulting in loss of steering control, serious injury, or even death.
Never allow the Implement to contact obstacles. (S3PT-12)
OPERATION
9.1 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
9.2 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.
9.3 Operating the Mower Wings
Wings are positioned with hydraulic cylinders. It is recommended that the tractor be equipped with three
hydraulic ports or a 3-spool control valve be used so that each section can be controlled independently.
Ensure the hydraulic cylinders and lines are filled with oil by holding the valve control levers in the raised
position until the cylinders fully retract (wings) and extend (center). Only operate the mower with both wings
fully lowered, NEVER operate the mower with a raised wing. Wait until the blades are at a complete stop
before raising wings. OPS-R-0015
Eagle 20 03/09
© 2009 Alamo Group Inc.
Operation Section 4-30
OPERATION
Transport Position
The center of gravity is raised and the mower more
prone to tipping when the wings are in the raised
position. When transporting, only raise the center
section high enough to clear ground obstacles. OPS-R-0016
When the Wings are folded for transport, the center of gravity is raised and the possibility of
overturn is increased. Drive slowly and use extreme caution when turning on hillsides.
Overturning the Implement could cause the Implement to overturn the Tractor and vice
versa resulting in serious injury or even death. Never fold wings on a hillside...the
Implement may overturn. (STI-02)
Operating Position
To lower the wings, remove the transport lock
braces and secure braces on storage bracket. DO
NOT drive out transport brace pins. The wing
cylinder may need to be retracted to remove tension
for brace removal. After removing brace bars,
extend wing hydraulic cylinders and fully lower
wings.
The valves operating wing cylinders should be
placed in the float position while mowing to allow the
mower to follow the contour of uneven terrain and to
prevent the wings from creeping up.
When
extending a wing over a ditch for mowing, place the
control valve lever detents in the center position.
This will give the mower more stability and prevent
the opposite wing from raising. DO NOT operate the mower with the valves in the detent position for extended
periods of time to prevent deck frame damage. OPS-R-0017
Use extreme care when lowering or unfolding the implement’s wings. Make sure no
bystanders are close by or underneath the wings. Allow ample clearance around the
implement when folding or unfolding the wings. Use extreme caution around buildings or
overhead power lines. (S3PT-05)
Eagle 20 03/09

Operation Section 4-31
OPERATION
To raise mower wings, drive the unit to a level area
and retract the wing hydraulic cylinders. DO NOT
raise wings with the mower positioned on an
embankment or other inclined position to prevent
overturning the mower. After the wings are fully
raised, install transport lock braces to prevent wings
from inadvertently falling. NOTE: If the transport
lock braces can not be easily installed, lower the
mower wings and remove rod end of cylinder and
adjust the rod clevis in or out to match the transport
brace length.
OPERATION
9.4 Driving the Tractor and Cutter
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.
OPERATION
Drive the tractor with the 3-Point lift arms in the raised position and lock the control lever in the transport detent
position to prevent damage to the mower driveline and tongue when turning.
Perform turns with the tractor and 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.
OPS-R-0018

Operation Section 4-32
OPERATION
9.5 Crossing Ditches and Steep Inclines
Damage resulting from over-collapse of the driveline’s inner profile and its outer housing
may allow the driveline to come loose from the Tractor which could cause bodily injury to the
operator or bystanders and/or extensive damage to the Tractor or Implement. OPS-R-0020
When contronted with an incline or ditch, do not
approach from an angle which is perpendicular or
straight on as damaged to over collapse of the
driveline may occur.
When crossing such terrain, the implement should
be fully lowered for a lower center of gravity and
added stability. OPS-R-0021
Eagle 20 03/09
© 2009 Alamo Group Inc.
Operation Section 4-33
OPERATION
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.
OPERATION
OPERATION
Inclines and ditches should be approached along a
line which is at an angle as shown. This type of
path will reduce the possibility of over-collapse of
the driveline and resulting damage. If the gradient
is so steep that such an approach increases the
possibility of a tractor roll-over, select an alternate
crossing path.
When operating the tractor and mower across
slopes and inclines, through ditches, and other
uneven terrain conditions, it is important to maintain
sufficient deck to ground clearance. Blade contact
with the ground may cause soil, rocks and other
debris to be thrown out from under the mower
resulting in possible injury and/or property damage.
Ground contact also produces a severe shock load
on the mower drive and to the mower blades
resulting in possible damage and premature wear.
OPS-R-0022
10. OPERATING THE TRACTOR AND IMPLEMENT
THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND
IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE. The operator must read and
understand the Safety and Operation Sections of the implement and tractor operator’s manuals. These
manuals must be read and explained to any operator who cannot read. Never allow someone to operate the
implement and tractor without complete operating instructions.
Before starting any operation, the operator must become familiar with the area to be worked in and any
obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special
attention should be paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area.
OPS-U- 0015
Extreme care should be taken when operating near loose objects such
as gravel, rocks, wire, and other debris. Inspect the area before
mowing. Foreign objects should be removed from the site to prevent
machine damage and/or bodily injury or even death. Any objects that
cannot be removed must be clearly marked and carefully avoided by the
operator. Stop mowing immediately if blades strike a foreign object.
Repair all damage and make certain rotor or blade carrier is balanced
before resuming mowing. (SGM-05)
Eagle 20 03/09
© 2009 Alamo Group Inc.
Operation Section 4-34
OPERATION
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the
operating parts of the mower head. These items could then swing outside the housing at
greater velocities than the blades. Such a situation is extremely hazardous and could result
in serious injury or even death. Inspect the cutting area for such objects before mowing.
Remove any like object from the site. Never allow the cutting blades to contact such items.
(SGM-06)
10.1 Foreign Debris Hazards
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
10.2 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
Eagle 20 03/09
© 2009 Alamo Group Inc.
Operation Section 4-35
OPERATION
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.
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;
OPERATION
-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, reduce streaking, and
make the final cut more uniform). (SRM-01)
10.3 Engaging the Power Take Off (PTO)
Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement
must be completely lowered and the deck positioned at a safe operating height. NEVER engage the PTO with
the implement in the raised position.
Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to
the on position, and slowly increase the engine speed until the PTO is operating at the rated speed. If you
hear unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the
implement to determine the cause of the noise or vibration and repair the abnormality. OPS-U- 0027
Do not let the Blades turn when the Mower Deck is raised for any
reason, including clearance or for turning. Raising the Mower deck
exposes the Cutting Blades which creates a potentially serious hazard
and could cause serious injury or even death from objects thrown from
the Blades. (SRM-07)
Do not put hands or feet under mower decks. Blade Contact can result
in serious injury or even death. Stay away until all motion has stopped
and the decks are securely blocked up. (SGM-09)

Operation Section 4-36
OPERATION
10.4 PTO RPM and Ground Speed
Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut.
Recommended speed for efficient mower performance is between 2 and 5 mph(3-8 kph). Operate the mower
at its full rated PTO speed to maintain blade speed for a clean cut. Refer to the tractor operator’s manual or
the tractor instrument panel for the engine speed and gear to provide the required PTO and desired ground
speed. Make sure that the mower is operating at its full rated speed before entering the vegetation to be cut.
If it becomes necessary to temporarily regulate engine speed, increase or decrease the throttle gradually.
Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause
Implement driveline or blade failures resulting in serious injury or death. (SG-26)
Mow at the speed that you can safely operate and control the tractor and mower. The
correct mowing speed depends on terrain condition and grass type, density, and height of
cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds
when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power
lines, or when debris and foreign objects are to be avoided. (SGM-07)
10.5 Operating the Mower
The mower is designed to cut vegetative material up to 2” in diameter. Travel at a speed that allows the
mower sufficient time to cut through the vegetation and maintain the operating speed at 540 rpm to prevent
overloading the mower and tractor and to produce a clean cut. Choose a driving pattern that provides the
maximum pass length and minimizes turning. Remember, sharp blades produce cleaner cuts and require
less power.
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 much reduced ground
speed to ensure control is maintained of the tractor and cutter. OPS-R-0026_H
Eagle 20 03/09
© 2009 Alamo Group Inc.
Operation Section 4-37
OPERATION
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
OPERATION
Do not mow with two machines in the same area except with Cab tractors with the windows
closed. (SGM-11)
OPERATION
Mow only in conditions where you have clear visibility in daylight or with adequate artificial
lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least
100 yards(90 m) in front and to the sides of the tractor and mower. Make sure that you can
clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions,
power lines, debris and foreign objects. If you are unable to clearly see these type of items
discontinue mowing. (SGM-1)
Avoid mowing in reverse direction when possible. Check to make sure there are no
persons behind the mower and use extreme care when mowing in reverse. Mow only at a
slow ground speed where you can safely operate and control the tractor and mower.
Never mow an area that you have not inspected and removed debris or foreign material.
(SGM-08)
Follow these guidelines to reduce the risk of equipment and grass fires
while operating, servicing, and repairing the Mower and Tractor:
-Equip the Tractor with a fire extinguisher in an accesible location.
-Do Not operate the Mower on a Tractor with an underframe exhaust.
-Do Not smoke or have an open flame near the Mower and Tractor.
-Do Not drive into burning debris or freshly burnt areas.
-Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating.
-Never allow clippings or debris to collect near drivelines, slip clutches, and gearboxes.
Periodically shut down the Tractor and Mower and clean clippings and collected debris from
the mower deck. (SGM-12)

Operation Section 4-38
OPERATION
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. NEVER raise the
mower wings while the blades are turning.
If the mower is operated in conditions that require
frequent sharp turning, the mower should be
equipped with a Constant Velocity driveline. CV
joints enable the tractor PTO shaft and mower
driveline to be angled safely up to 80 degrees with
no damage to the mower or driveline. OPS-R-0027
Do not let the Blades turn when the Mower Deck is raised for any
reason, including clearance or for turning. Raising the Mower deck
exposes the Cutting Blades which creates a potentially serious hazard
and could cause serious injury or even death from objects thrown from
the Blades. (SRM-07)
Stay alert and watch for trees, low hanging limbs,
power lines, and other overhead obstacles and solid
ground objects while you are operating. Use care
to avoid hitting these items. OPS-R-0028
Eagle 20 03/09
© 2009 Alamo Group Inc.
Operation Section 4-39
OPERATION
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.
OPERATION
OPERATION
When mowing across uneven areas such as road shoulders, ditch edges, and other uneven terrain, position
mower so that one support wheel is near the highest point to prevent blades from cutting into gravel or dirt
which can cause rapid blade wear and extremely severe shock loads on the drivetrain resulting in rapid wear
or damage to these components. Blades contacting the ground may cause objects to be thrown out from
under the mower deck. Always avoid operating the mower at a height or position which may cause the blades
to contact the ground. Cutting into the berm or edge of the ditch will cause abnormal and accelerated blade
wear and possible blade component failure. OPS-R-0029

Operation Section 4-40
OPERATION
10.6 Shutting Down the Implement
To shut down attached mower head, first bring the
tractor to a complete stop. Decrease engine RPM
to idle then disengage cutterhead. The mower head
will come to a complete stop within a suitable
amount of time. Do not engage or disengage the
cutterheads at a high RPM unless there is an
emergency situation.
11. 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 the center section and both wings to the ground. If the mower
will be stored with the wings in the raised position, install both wing transport lock braces. If the mower is not
resting securely on the ground, block the mower up securely before attempting to disconnect it from the
tractor.
Use extreme care to keep feet and hands from under the mower and clear of any pinch points. OPS-R-0030
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)
Eagle 20 03/09
© 2009 Alamo Group Inc.
Operation Section 4-41
OPERATION
Park the tractor on a level surface, place the
transmission in park or neutral and apply the
parking brake, lower the attached implement to the
ground, shut down the engine, remove the key, and
wait for all motion to come to a complete stop
before exiting the tractor. OPS-U- 0016
OPERATION
OPERATION
Never unhitch without using the Tongue Jack. The Tongue is very heavy. Attempting to lift
the Tongue without using the Tongue Jack could cause strains or other injury. Allowing the
tongue to fall suddenly and unexpectedly could result in crushing injury. Use the Tongue
Jack for lifting the Implement only. Overloading the Tongue Jack can cause failure with
possible serious bodily injury or even death. (STI-04)
When disconnecting the mower the tractor should
be completely shut down and secured in position.
Relieve hydraulic pressure by moving the control
levers back and forth several times. Lower the
parking jack and raise the mower until the tongue
clevis is no longer resting on the tractor drawbar
and is supported solely by the jack. The jack
should be in a near vertical position with the ground
and can be adjusted by loosening the positioning
nut and moving the jack up to 15 degrees in each
direction.
Also make sure that the jack foot is
securely resting at ground level or securely
supported by a block before raising the mower.
Once the mower tongue is being supported entirely
by the jack, remove the hitch bolt, locknut, and
washers. Remove the hydraulic hoses from the
tractor and secure to the mower to prevent contact
with dirt.
After disconnecting the mower hitch, remove the
mower driveline from the tractor PTO shaft. Place
the driveline in its storage bracket to prevent it from
contacting mud or dirt which can contaminate the
universal joint bearings and shorten the life of the
driveline.
After the driveline has been removed from the
tractor, place the PTO master shield back in the
operating position. OPS-R-0031

Operation Section 4-42
OPERATION
12. MOWER STORAGE
It is recommended that the mower be stored with the center section and both wings fully lowered to ground
level. If the mower is stored with the wings in the raised position, select a level area and install wing transport
braces to prevent the wings from falling BEFORE disconnecting the mower hitch from the tractor.
Properly preparing and storing the mower at the end of the season is critical to maintaining its appearance
and to help ensure years of dependable service. The following are suggested storage procedures:
•
•
•
•
•
•
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
Never allow children to play on or around Tractor or Implement. Children can slip or fall off
the Equipment and be injured or killed. Children can cause the Implement to shift or fall
crushing themselves or others. (SG-25)
13. TRANSPORTING THE TRACTOR AND IMPLEMENT
Inherent hazards of operating the tractor and implement and the possibility of accidents are not left behind
when you finish working in an area. Therefore, the operator must employ good judgement and safe operation
practices when transporting the tractor and implement between locations. By using good judgement and
following safe transport procedures, the possibility of accidents while moving between locations can be
substantially minimized. OPS-U- 0017

OPERATION
•
Thoroughly clean all debris off the mower to
prevent damage from rotting grass and standing water.
Lubricate all mower grease points and fill gearbox oil levels as detailed in the maintenance
section.
Tighten all bolts and pins to the recommended
torque.
Check the mower for worn and damaged
parts. Perform repairs and make replacements immediately so that the mower will be
ready for use at the start of the next season.
Store the mower in a clean, dry place with the
mower housing resting securely on blocks or
at ground level.
Keep the driveline yoke from sitting in water,
dirt and other contaminants.
Use spray touch-up enamel where necessary
to prevent rust and maintain the appearance of
the mower.
OPERATION
OPERATION
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
Before transporting the tractor and mower, idle the
tractor engine, disengage the PTO and wait for all
mower moving parts to come to a complete stop.
Once all mower parts are completely stopped, raise
the mower to transport height. NOTE: When
raising the mower, maintain at least 1” clearance
between the driveline and mower deck. If additional
mower deck height is needed for safe transport,
disconnect the driveline from the tractor and secure
its end to the mower deck. The mower can then be
raised to the maximum lift height.. OPS-R-0033
If the tractor’s hydraulic pump is not independent of
the tractor PTO, or if the tractor PTO has to be run
to have hydraulic power, disconnect the mower
driveline from the tractor PTO output shaft. Secure
the driveline to the mower deck to prevent driveline
damage or loss during transport. OPS-R-0034
Before transporting the tractor on a public roadway
or boarding a trailer for transport, the tractor brake
pedals should be locked together. Locking the
pedals ensures that both wheels brake
simultaneously while stopping, especially when
making an emergency stop.
Use extreme caution and avoid hard applications of
the tractor brakes when towing heavy loads at road
speeds. Never tow the implement at speeds
greater than 20 MPH (25 kph). OPS-U- 0018

OPERATION
13.1 Tire and Wheels
Laminated Sectional Tires are designed for conditions where puncture proof performance is required and
the mower will not be transported for long distances on roadways. Transport speed for laminated tires should
not exceed 20 MPH. Excessive speed can cause damage to the machine and tire sections. Laminated tires
must be installed such that the rubber segments lay with the ground.

Foam Filled used Airplane Tires are ideal for conditions where a puncture proof tire is needed and the
mower is frequently transported between locations.
Pneumatic Tires Implement tires are ideal for frequent long distance towing, however, they are not puncture
proof and are not recommended for mowing brushy areas or other conditions that could damage the tires.
Check side wall of tire for proper inflation pressure. DO NOT over-inflate. OPS-R-0035
13.2 Transporting on Public Roadways
Extreme caution should be used when transporting the tractor and mower on public roadways. The tractor
must be equipped with all required safety warning features including a SMV emblem and flashing warning
lights to alert drivers of the tractor’s presence. Remember that roadways are primarily designed for
automotive drivers and most drivers will not be looking out for you, therefore, you must look out for them.
Check your side view mirrors frequently and remember that vehicles will approach quickly because of the
tractor’s slower speed. Be extremely cautious when the piece of equipment that you are towing is wider than
the tractor tire width and/or extends beyond your lane of the road.
Make sure that a proper size safety tow chain is secured between the tractor, flex arm and mower before
entering a public road. Secure the center section at a safe transport height by placing additional stroke control
spacers on the center axle cylinder and then lower the mower. Secure the mower wings in the raised position
with the transport lock braces. OPS-R-0036
Only tow the Implement behind a properly sized and equipped Tractor
which exceeds the weight of the Implement by at least 20%. DO NOT
tow the Implement behind a truck or other type of vehicle. Never tow the
Implement and another Implement connected in tandem. Never tow the
Implement at speeds over 20 MPH. (STI-06)

OPERATION
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
OPERATION
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
newer model tractors have plenty of lighting to
provide warning signals and operating lighting, most
older models are only equipped with operating lights.
Consult an authorized tractor dealer for lighting kits
and modifications available to upgrade the lighting on
older tractor models. OPS-U- 0021

OPERATION
When operating on public roads, have
consideration for other road users. Pull to the side
of the road occasionally to allow all following traffic
to pass. Do not exceed the legal speed limit set in
your country for agricultural tractors. Always stay
alert when transporting the tractor and implement
on public roads. Use caution and reduce speed if
other vehicles or pedestrians are in the area. OPSU- 0022
13.3 Hauling the Tractor and Implement
Before transporting a loaded tractor and implement,
measure the height and width dimensions and gross
weight of the complete loaded unit. Ensure that the
load will be in compliance with the legal limits set for
the areas that will be traveled through. OPS-U- 0024

Ensure that both brake pedals are locked together
when operating on public roads. OPS-U- 0023
OPERATION
OPERATION
Use adequately sized and rated trailers and
equipment to transport the tractor and implement.
Consult an authorized dealer to determine the proper
equipment required. Using adequately sized chains,
heavy duty straps, cables and/or binders, securely tie
down both the front and rear of the tractor utilizing the
proper tie down locations as specified by the tractor
manufacturer. OPS-U- 0025
Arrange the chains so that when tightened, the
chains are pulling downward and against
themselves. Carefully tighten the securing chains or
other fasteners using boomers or binders to apply
maximum tension.
Use extreme care when
attaching and removing the securing devices as the
extreme tension involved when released has the
potential to inflict serious injury.
While hauling the tractor and implement, make
occasional stops to check that the tractor and
implement have not moved or shifted and that the
securing chains have maintained tension. If during
transport a hard braking, sharp turning, or swerving
action was performed, stop at the next safe location
to inspect the security of the load. OPS-U- 0026

BLADE SERVICING
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.
Use only original equipment blades on this cutter. They are made of special heat-treated
alloy steel. WILL-FIT BLADES MAY NOT MEET SPECIFICATIONS AND MAY FAIL
CATASTROPHICALLY AND CAUSE BODILY INJURY OR DEATH.
Inspect Blades daily for abnormal wear. If Blades have a notch worn into the leading edge
at the lower bend more than a 1/2" DEEP (FIGURE 12) (due to running in gravel and/or the
ground), REPLACE BOTH BLADES ON THAT CARRIER IMMEDIATELY. Failure to
replace such abnormally worn blades may lead to catastrophic failure of the blade and
ejection of the broken part with tremendous force which may cause bodily injury or death!
Eagle 20 03/09
© 2009 Alamo Group Inc.
Maintenance Section 5-13
MAINTENANCE
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
BLADE SHARPENING
Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as shown in
FIGURE 11. 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.
IMPORTANT: 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.
MAINTENANCE
Never work under equipment supported by a hydraulic device because it may drop if the
control is actuated (even with the engine stopped) or in the event of hose failure, etc.
Always use a secure support for equipment which must be serviced while in the raised
position.
NOTE: Replace Blades in pairs after no more than 1/2" notch wear!
BLADE REMOVAL
To remove blades for sharpening or replacement,
remove the cover plate on deck of cutter near each
gear box. Remove locknut from blade bolt - note:
These are Left-Hand Threads. Inspect lock nut after
removal and replace if threads are damaged.
Always replace nut when replacing blade bolt.
When installing blades, be sure to check blade bolt
pivot diameter for wear. Replace bolt if worn more
than 1/4" at any point. Install blade bolts with worn
side of bolt away from the center of the blade carrier.
Tighten lock nut to 300 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 , PTO disengaged, and the cutter blocked in the
raised position.

Maintenance Section 5-14
MAINTENANCE
BLADE CARRIER REMOVAL
Remove cotter pin and loosen slotted nut on gear box shaft. Loosen but do not remove the nut until the blade
carrier is loosened. Use a suitable two-jaw gear puller to pull carrier off tapered gear box 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 INSPECTION
Failure to replace a worn blade carrier bushing as described above may lead to catastrophic
failure of the blade, blade bolt, and/or blade bolt nut resulting in the ejection of the broken
parts out from under the mower at tremendous speed and force which could result in serious
bodily injury or death.
Eagle 20 03/09

Maintenance Section 5-15
MAINTENANCE
Blade bolt fit into carrier bushings should be checked every time blades are changed. The blade bolt should fit
into carrier bushings as a snug slip fit. If the blade bolt fit appears to be loose or sloppy, measure the square
hole in bushing. If the bottom of the square hole is 1/16” or greater than the square shoulder of the new blade
bolt the bushings should be replaced. Bushings can be removed by cutting bushing head where it is welded to
carrier bar. Once head is removed bushing can be pressed out of bar. Clean and grind top of blade bar so new
bushing can be installed and welded. Bushing should be pressed into bar so that bottom of bushing is flush
with bottom of blade bar. Use low hydrogen rod to weld bushing in place.
MAINTENANCE
BLADE CARRIER INSTALLATION
Clean the taper and keyway on both the blade carrier and output shaft. Position carrier on the gear box output
shaft and install flat washer and 1" hex nut. Tighten the nut holding the blade carrier to minimum 450 ft.
pounds. Strike the carrier on 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 and
spread cotter pin.
MAINTENANCE
NOTE: After a few hours of operation always recheck blade carrier retaining nut torque.
Avoid personal injury. Do not work under cutter without support blocks to keep frame from
falling.
SLIP CLUTCHES
A slip clutch is incorporated on each outboard driveline. The slip clutches are designed to slip, absorb the
shock load, and protect the drivelines of the mower.
After the first hour of operation, the slip clutches should be checked for overheating. After this first check,
inspect weekly or anytime there is overheating. To adjust the slip clutch, tighten the spring bolts 1/8
(maximum) turn at a time. See Figure Mnt-R-0018 for minimum dimension. DO NOT tighten springs beyond
1-15/32" length (from top of washer to pressure plate).
Each 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/frozen together. Should
this occur refer to the procedure described in the "Seasonal Clutch Maintenance" section on the next page.
There are four friction lining plates in the slip clutch. These should be checked weekly for oil or grease, wear,
and moisture which could cause corrosion on the drive plates.

Maintenance Section 5-16
MAINTENANCE
TIRES AND WHEELS
Before working on any tires and wheels make certain the Cutter is jacked up high enough and securely
supported. When installing laminated or airplane tires, be sure the flat side of the lug nut is against the Wheel.
Maximum airplane tire inflation pressure is 50 PSI, minimum inflation pressure is 20 PSI. Inflate ribbed
implement tires to manufacturer rated PSI as shown on the tire sidewall.
SEASONAL TORQUE LIMITER 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/frozen
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 (Figure MntP-R-0018) on springs
until the springs can freely rotate, 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 Figure Mnt-R0018.
4. Engage the PTO (approximately one second)
and then quickly disengage it. The friction
lining plates should break loose (check the
mark).
5. Turn tractor off and tighten the nuts on the
springs to their original position of 1-9/16"
compressed spring length (top of washer to
pressure plate).

MAINTENANCE
When installing Sectional Tires and Wheels note the direction of travel and the curvature of rubber segments in
the tire (See Assembly Section). Do not exceed 15 M.P.H. on Sectional Tires. When removing Airplane Tires,
let all of the air out of the tire before removing lug nuts or wheel bolts or nuts. Remove valve core to make
certain that there is no air pressure left in tube before separating wheel halves to dismount tires. DO NOT
LOOSEN WHEEL CLAMP BOLTS BEFORE PRESSURE IS REMOVED FROM TUBE AND TIRE TO
PREVENT EXPLOSIVE SEPARATION OF WHEEL HALVES WITH POSSIBLE SERIOUS BODILY INJURY.
MAINTENANCE
HYDRAULIC HOSES
MAINTENANCE
Replace pinched and broken Hydraulic Hoses at once. Tighten any Hydraulic Fitting with fluid leaking from it. If
fluid still leaks, loosen the fitting, apply a pipe thread compound to the threads and tighten. Care must be
exercised when tightening Hydraulic Fittings. Too much tightening can cause the fittings to crack and require
replacement fittings.
Although a small amount of oil will be present from bleeding at all Hydraulic Fittings, significant amounts of oil
leaking around the Breather Plug on the Cylinder indicates that the seal in the Cylinder is worn out. Replace
the seals in the Cylinder immediately before the Cylinder is damaged or too much hydraulic fluid is lost.
SKID SHOES
Skid shoes are made of carbon steel to reduce wear and increase service life. Premature wear can be caused
by the cutter Wing sections being set too low which allows the Wing Skid Shoes to drag on the ground.
Dragging the Skid Shoes on the ground or running the Skid Shoes into solid objects can contribute to early
frame failure on the cutter. Replace worn Skid Shoes as required.
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:
6.
7.
8.
9.
10.
11.
Thoroughly clean the cutter.
Lubricate the cutter as covered in Maintenance Section.
Tighten all bolts and pins to the recommended torque.
Check the cutter for worn or damaged parts. Make replacements immediately.
Store the cutter in a clean, dry place with the cutter housing resting on blocks.
Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the cutter.

STEP 7
Install the Shaft Assembly into the Main Housing. FIGURE Mnt-R-0070. Install the Input Cap and check the
gap between the Main Housing and the Input cap to determine the approximate amount of Shims that will be
required. Remove the Input Cap and install the Gaskets. Reinstall the Cap and install four Bolts. FIGURE MntR-0071.
NOTE! These four Bolts should be installed in every other bolt hole of the Cap When tightening, the second
bolt tightened should be 180 degrees away from the first bolt tightened. Check how the Input Shaft turns. When
turned, if tight, additional Shims are needed. If loose and the Shaft can be moved from side to side, Shims
need to be removed. The correct adjustment of the Input Shaft Bearings is when the Shaft turns freely, but
cannot be moved from side to side in the Housing.

MAINTENANCE
Install the second Spindle Hub assembly on the Main Housing. Check the amount of backlash present
between its Gear and the Gear on the Input Shaft. The amount of backlash between these two Gears needs to
be set to the same amount that was set on the first Gear mesh. Add or subtract Shims as required. Once this
adjustment is made, remove the Hub Cap and apply sealer as before, then reinstall on Housing. Install all eight
bolts and tighten to a torque of 31 to 34 foot pounds. FIGURE Mnt-R-0076-0077.
