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 [email protected] or Fax
AEM VHS Video at (830) 372-9529 or mail in a completed copy of the form on the back of this page to
AEM VHS Video 1502 E Walnut Street, Seguin, TX 78155. and request the VHS video version. Please
include your name, mailing address, mower model and serial number.

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

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

Safety Section 1-4
SAFETY
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)
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)
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)

Safety Section 1-5
SAFETY
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)
SAFETY
SAFETY
Do not operate Mower if excessive vibration exists.
Shut down PTO and the Tractor
engine. Inspect the Mower to determine the source of the vibration. If Mower blades are
missing or damaged replace them immediately.
Do not operate the mower until the
blades have been replaced and the Mower operates smoothly. Operating the Mower with
excessive vibration can result in component failure and broken objects to be thrown
outward at very high velocities. To reduce the possibility of property damage, serious injury,
or even death, never allow the Mower to be operated with blades missing. (SFL-4)
Operate this Equipment only with a Tractor equipped with an approved rollover-protective system (ROPS). Always wear seat belts. Serious injury or
even death could result from falling off the tractor--particularly during a turnover
when the operator could be pinned under the ROPS. (SG-7)
BEFORE leaving the tractor seat, always engage the brake and/or set
the tractor transmission in parking gear, disengage the PTO, stop the
engine, remove the key, and wait for all moving parts to stop. Place the
tractor shift lever into a low range or parking gear to prevent the tractor
from rolling. Never dismount a Tractor that is moving or while the engine
is running. Operate the Tractor controls from the tractor seat only. (SG-9)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (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)

Safety Section 1-6
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)
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 1-7
SAFETY
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health. (SG-23)
SAFETY
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)
The rotating parts of this machine have been designed and tested for rugged use.
However, the blades could fail upon impact with heavy, solid objects such as metal guard
rails and concrete structures. Such impact could cause the broken objects to be thrown
outward at very high velocities. To reduce the possibility of property damage, serious
injury, or even death, never allow the cutting blades to contact such obstacles. (SGM-4)
Extreme care should be taken when operating near loose objects such
as gravel, rocks, wire, and other debris. Inspect the area before
mowing. Foreign objects should be removed from the site to prevent
machine damage and/or bodily injury or even death. Any objects that
cannot be removed must be clearly marked and carefully avoided by the
operator. Stop mowing immediately if blades strike a foreign object.
Repair all damage and make certain rotor or blade carrier is balanced
before resuming mowing. (SGM-05)
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the
operating parts of the mower head. These items could then swing outside the housing at
greater velocities than the blades. Such a situation is extremely hazardous and could result
in serious injury or even death. Inspect the cutting area for such objects before mowing.
Remove any like object from the site. Never allow the cutting blades to contact such items.
(SGM-06)
Mow at the speed that you can safely operate and control the tractor and mower. The
correct mowing speed depends on terrain condition and grass type, density, and height of
cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds
when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power
lines, or when debris and foreign objects are to be avoided. (SGM-07)
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 1-8
SAFETY
Follow these guidelines to reduce the risk of equipment and grass fires
while operating, servicing, and repairing the Mower and Tractor:
-Equip the Tractor with a fire extinguisher in an accesible location.
-Do Not operate the Mower on a Tractor with an underframe exhaust.
-Do Not smoke or have an open flame near the Mower and Tractor.
-Do Not drive into burning debris or freshly burnt areas.
-Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating.
-Never allow clippings or debris to collect near drivelines, slip clutches, and gearboxes.
Periodically shut down the Tractor and Mower and clean clippings and collected debris from
the mower deck. (SGM-12)
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)
GRASS KING 03/09
© 2009 Alamo Group Inc.
Safety Section 1-9
SAFETY
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)
SAFETY
SAFETY
Rotary Mowers are capable under adverse conditions of throwing
objects for great distances (300 feet or more) and causing serious injury
or death. Follow safety messages carefully.
STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable
condition;
-Mower sections or Wings are running close to and parallel to the ground without exposed
Blades;
-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)
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)
Connecting or Disconnecting Implement Safety Instructions and
Practices
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
PTO. Use of an adapter can double the operating speed of the Implement resulting in
excessive vibration, thrown objects, and blade and implement failure. Adapter use will also
change the working length of the driveline exposing unshielded driveline areas. Serious
bodily injury and/or equipment failure can result from using a PTO adapter. Consult an
authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.
(S3PT-14)
GRASS KING 03/09

Safety Section 1-10
SAFETY
Always shut the Tractor completely down, place the transmission in park, and set the
parking brake before you or anyone else attempts to connect or disconnect the Implement
and Tractor hitches. (S3PT-15)
Never operate the Tractor and Mower if the Implement input driveline is directly connected
to the Tractor transmission. Tractor braking distances can be substantially increased by
the momentum of the rotating Mower blades driving the Tractor transmission even though
the Tractor clutch has been disengaged. Install an over running clutch between the Tractor
PTO and the Mower driveline to prevent this potentially dangerous situation. (S3PT-16)
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)
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.
(S3PT-02)
Allow sufficient clearance for the Implement to swing outward while turning. Implements
carried behind the Tractor will swing outside the tire path when making turns. Contacting a
solid object while turning will cause equipment damage and possible injury. (S3PT-20)
Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in
such a way as to be clearly visible and legible. When transporting the
Equipment use the Tractor flashing warning lights and follow all local
traffic regulations. (SG-6)

SAFETY
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)
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)
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)
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)

INTRODUCTION
These Flail Mowers are designed for medium-duty work. They can mow pastures and control grass and
weeds on highways or industrial sites.
For Non-Agricultural use, OSHA, ASAE, SAE, and ANSI standards require the use of Chain
Guards, Deflectors, or Solid Skirts at all times. The Mower manufacturer strongly
recommends the use of Chain Gaurds, Deflectors, or Solid Skirts for Agricultural purposes
as well to reduce the risk of property damage, serious bodily injury, or even death from
objects thrown out by or from contact with the Cutting Blades..
Mower Orientation: Front and rear, and left and right are determined by the normal direction of travel (the
same as your automobile).
At least 20% of the tractor’s total weight must be on the front tires with the Mower lifted to
provide adequate traction for safe steering under good conditions. Slow down on hills,
rough terrain, and curves.
Front and rear, and left and right are determined by the normal direction of travel (the same as on your

ASSEMBLY
The GRASS KING will attach to most tractors with Cat I or Cat II Hitch and 540 PTO RPM.
ASSEMBLY
TRACTOR PREPARATION
For satisfactory operation the Grass King machine should be attached to tractors that are of sufficient size and
horse power. The Grass King flail mower requires a minimum 40 horse power and a minimum base tractor
weight of 4500 pounds. The Grass King rotary mower requires a minimum 50 horse power and a minimum
base tractor weight of 6000 pounds.
In addition, the left rear tire should have a full charge of liquid ballast. The rotary Grass King requires that the
rear tractor tires be spread to a minimum 96 inches outside dimension.
Note: When attaching the rotary Grass King head to the tractor, it may be necessary to move the main frame
further to the right if the head hits the tire when the head is tilted up. This is done by loosening the bolts that
attach the hitch weldment to the mainframe weldment and sliding the frame to the right. It may be necessary to
loosen the pump suction line and readjust in order to prevent the hose from kinking when adjusting the frame.
In order to move the frame the maximum amount to the right, the hitch weldment attachment bolts on the right
hand side will have to be completely removed so that the hitch can be positioned on the left side of the cylinder
lug. (See A-frame illustration in the parts section).
DEALER SETUP INSTRUCTIONS
Assembly of this mower is the responsibility of the Alamo dealer. The mower should be delivered to the owner
completely assembled, lubricated, and adjusted for normal cutting conditions.
Set up mower as received from the factory with these instructions. Open parts box and lay parts out to make
location easy. Refer to the parts lists and exploded view drawings for more detail.
This mower is shipped partially assembled. Assembly will be easier if components are aligned and loosely
assembled before tightening hardware.
Always use personal protection devices such as eye, ear and foot protectors during
assembly.

OPERATION
Alamo Industrial Grass King flail mowers are manufactured with quality material by skilled workers. These
mowers are designed to cut grass, weeds, small brush, and other vegetative material up to 2” in diameter. The
mower is equipped with protective deflectors and chain guards to prevent objects being thrown from the mower
by the blades, however, no shielding is 100% effective. All shields, guards, deflectors, and chains equipped on
the unit must be maintained on the mower in good operational condition.
It is the operator’s responsibility to be knowledgeable of all potential operating hazards and to take every
reasonable precaution to ensure oneself, others, animals, and property are not injured or damaged by the
mower, tractor, or a thrown object. Do not operate the mower if passersby, pets, livestock, or property are
within 100 yards of the unit.
This section of the Operator’s Manual is designed to familiarize, instruct, and educate safe and proper mower
use to the operator. Pictures contained in this section are intended to be used as a visual aid to assist in
explaining the operation of a Grass King flail mower and are not specific to any model. Some pictures may
show shields removed for purposes of clarity. NEVER OPERATE this implement without all shields in place
and in operational condition. The operator must be familiar with mower and tractor operation and all associated

OPERATION
3.7 Power Take Off (PTO)
Only operate the mower on a tractor equipped to operate at 540 RPM PTO speed. Tractors operating at 540
rpm will have a 1-3/8” diameter 6-spline PTO shaft stub. Refer to the tractor operator’s manual for operating
the PTO at the proper 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. Consult an
authorized tractor dealer to purchase and install an over-running clutch if needed.
(S3PT-14)
Never operate the Tractor and Mower if the Implement input driveline is directly connected
to the Tractor transmission. Tractor braking distances can be substantially increased by
the momentum of the rotating Mower blades driving the Tractor transmission even though
the Tractor clutch has been disengaged. Install an over running clutch between the Tractor
PTO and the Mower driveline to prevent this potentially dangerous situation. (S3PT-16)
4. GETTING ON AND OFF THE TRACTOR
Before getting onto the tractor, the operator must read and completely understand the mower and tractor
operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for a

Operation Section 4-11
OPERATION
1. With the tractor shut down and secured in
position, move the hydraulic remote valve
lever back and forth several times or place
the hydraulic lever in the float position to
relieve all hydraulic pressure. When
connecting the mower hydraulic lines to the
tractor, keep the hose, quick couplers, and
swivels free of dirt and other contaminants.
Wipe all dirt and other contaminants from the
tractor hydraulic remote ports and mower
hydraulic hose coupler with a clean rag
before connecting.
2. Connect mower hydraulic hose to the tractor
remote port. Ensure the coupler locks in
place making a good connection. Different
tractor models receive hydraulic lines
differently. Refer to the tractor Operator’s Manual for connecting and operating hydraulics
for your particular model tractor.
Some tractor models allow the remote
hydraulic valve to be configured for single
acting cylinders. Refer to tractor operators
manual and follow the appropriate
instructions for single acting cylinder
operation.
3. Ensure hydraulic hoses will not contact or
become entangled with mower drivelines, do
not bind when turning, or become pinched or
kinked when operating, raising, and lowering
the mower.
OPERATION
OPERATION
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)
7. SETTING MOWER CUTTING HEIGHT
Properly setting the cutting height is essential for efficient and safe operation. A properly set mower makes a
more uniform cut, distributes clippings more evenly, increases tractor efficiency, and follows 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.
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)
Roller Height Adjustment
The mower’s cutting height is set by positioning
the roller assembly for each mower section.
Each section must be set at the same height to
ensure an even cut across the entire width of the
mower.
1. Place the tractor and mower on a level
surface and completely lower the mower to
the ground.
2. Shut down the tractor, place the
transmission in park, and set the parking
brake before dismounting.
3. One section at a time, place lifting device
(scissors jack or hydraulic jack) under center
of cutter housing.
GRASS KING 03/09

Operation Section 4-12
OPERATION
Leveling Deck
To Facilitate a safe and efficient mowing
operation, the mower should be operated
parallel to the ground at all times. Never operate
if front or rear of mower is tilted upward. Objects
may be discharged at high speeds causing
possible injury or even death.
Adjust Top Link to level mower roller
adjustment. Side Skid Shoes should always be
parallel
to
ground
throughout
the
full
adjustment range. Adjust cutting height of
machine by raising or lowering rear roller as
specified in Operation Section.
Do not let the Blades turn when the Mower Deck is raised for any
reason, including clearance or for turning. Raising the Mower deck
exposes the Cutting Blades which creates a potentially serious hazard
and could cause serious injury or even death from objects thrown from
the Blades. (SRM-07)

Operation Section 4-13
OPERATION
4. Remove hex nuts, washers and carriage bolts
from bracket at each end of roller. Make certain
that roller bracket is free to move once the
fasteners are removed. A stuck roller could drop
unexpectedly and cause injury.
5. Use lifting device to reposition cutter housing to
desired cutting height. Align bracket holes with
cutter housing, then reinstall hardware.
6. Lower cutter housing to the ground and remove
lifting device.
7. Set cutting height according to procedures
above for remaining two cutter sections. Make
sure that all three rollers are set at the same
height to ensure an even cut across the entire
width of the mower.
OPERATION
8. DRIVELINE ATTACHMENT
OPERATION
The driveline yoke and tractor PTO shaft must be
dirt free and greased for easy and secure
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 is securely attached to the PTO
shaft. Push and pull the driveline back and forth
several times to ensure a secure attachment.
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)
8.1 Driveline Length Check
Before operating the Implement, check to make sure the Implement input driveline will not
bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates
the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out
can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and
through the support bearings or downward onto the PTO shaft, breaking it off. A broken
driveline can cause personal injury. (S3PT-18)
When fitting the mower to the tractor, the telescoping driveline must be inspected to ensure that at its most
compressed position, the profiles do not “bottom out”, and when at its farthest extended position, there is
sufficient engagement between the profiles to operate safely. At its shortest length, there must be at least a 1”
clearance between each profile end and opposite profile universal joint. At its farthest operating extension, a
minimum profile engagement of 8” must be maintained.
GRASS KING 03/09
© 2009 Alamo Group Inc.
Operation Section 4-14
OPERATION
Shorten the driveline profiles as follows:
1. Remove the driveline from the tractor.
2. Position the mower to the point with the
shortest distance between the tractor PTO
shaft and cutter gearbox. Shut down the
tractor and securely block the mower in this
position.
3. Pull driveline apart and reattach yoke to PTO
shaft.
4. Hold driveline sections parallel to one
another and measure back 1” from yoke of
each shaft and place mark on opposite
section. Cut this length off with a saw.
5. Round off all sharp edges and debar.
6. Thoroughly grease then reinstall the
driveline.
7. Recheck for proper operation.
Engagement Check Procedure
1. 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.
2. Mark the inner driveline shield 1/8” from the end of the outer shield.
3. Disconnect the driveline from the tractor and separate the two driveline halves.
4. Measure the distance from the mark to the end of the inner profile. This length is the amount the driveline
profiles were engaged.
GRASS KING 03/09
© 2009 Alamo Group Inc.
Operation Section 4-15
OPERATION
“Bottoming Out” Check Procedure”
1. Disconnect driveline from the tractor and
slide the profiles together until fully
compressed.
2. Place a mark on the inner shield 1/8” from
the end of the outer shield and reattach the
driveline to the PTO shaft.
3. With the PTO NOT TURNING, slowly drive
the tractor with mower attached through the
sharpest turn possible and watch shaft
movement. With the PTO NOT TURNING,
slowly drive the tractor with the mower
attached through the most severe terrain
conditions expected and watch shaft
movement.
4. If the distance between the mark and the
outer shield becomes less than 2” at any
point there is a potential problem bottoming
out the driveline and the driveline should be
shortened.
OPERATION
5. If the engaged length is less than 8”, 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.
OPERATION
9. PRE-OPERATION INSPECTION AND SERVICE
Before each use, a pre-operation inspection and service of the mower and tractor must be performed. This
includes routine maintenance and scheduled lubrication, inspecting that all safety devices are equipped and
functional, and performing needed repairs. Do not operate the mower and tractor if the pre-operation
inspection reveals any condition affecting safe operation. Perform repairs and replacement of damaged and
missing parts as soon as noticed. By performing a thorough pre-operation inspection and service, valuable
down time and repair cost can be avoided.
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)

10. DRIVING THE TRACTOR AND MOWER
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 mower and the tractor operating controls are set for safe transport. To ensure safety while driving
the tractor with an attached mower, review the following.
Power for operating the mower is supplied from the tractor PTO. Refer to your tractor manual instructions for
engaging and disengaging the PTO. Start the tractor and idle at a slow engine speed until oil is being pumped.
Always engage the PTO at low engine RPM and run the mower for a short period until all air is removed from
the hoses. Keep all person's well clear of mower since blades can throw objects with great velocity for a
considerable distance! KEEP CLEAR!
Check the fluid level in the Hydraulic Tank and add oil if required. As the air has been forced out of the Hoses,
it goes into the Hydraulic Tank and reduces the volume of oil. Maintain the oil level within the sight gauge
located on the side of the reservoir. Never fill the tank above the sight gauge to allow for the expansion of the
oil. The tank maintains pressure after the mower has been run. Stand off to one side when removing the
breather cap element to prevent possible injury. To relieve pressure remove the breather cap element and
depress the spring loaded pressure valve to release any excess air. Fill with Dexron ll Automatic
Transmission Fluid.
R
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)
GRASS KING 03/09
© 2009 Alamo Group Inc.
Operation Section 4-23
OPERATION
Read all safety instructions. Decals on the Mower warn you of particular and multiple hazards. Some decals
are attached close to part of the Mower where there is a possible hazard. Read and make sure you
understand the safety messages before you operate the implement. Keep all decals clean and readable.
Replace lost or damaged decals.
OPERATION
Transport only at speeds where you can maintain control of the
equipment. Serious accidents and injuries can result from operating this
equipment at high speeds. Understand the Tractor and Implement and
how it handles before transporting on streets and highways. Make sure the Tractor steering
and brakes are in good condition and operate properly.
OPERATION
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)
10.1 Starting the Tractor
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 PTO is
disengaged before starting the tractor.

10.2 Brake and Differential Lock Setting
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes.
When operating down a hill or on a 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.
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.
10.3 Operating the Mower Wing
Transport Position
With tractor engine running, turn off the tractor
PTO Switch and wait for cuttershaft(s) to stop
rotating. Using the tractor remote lever to fully
raise mower wing unit.
Then lift up transport link to pin attaching
cylinder to actuator on A-frame. Attach pin clip
once the pin is through the transport link hole
and attach the clip pin to keep in place.
Make certain that the control lever is in the
“HOLD” position when transporting unit.

OPERATION
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 MOWING CONDITIONS, THE
BRAKE PEDALS SHOULD BE LOCKED
TOGETHER TO PROVIDE THE MOST
EFFECTIVE BRAKING ACTION. OPS-F-0044
OPERATION
OPERATION
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)
The mower’s center of gravity is raised making the mower more prone to tipping when the wings are in the
raised position. Use extreme caution when towing the mower in the transport position and avoid uneven
terrain which could upset the mower.
When the Wings are folded for transport, the center of gravity is raised and the possibility of
overturn is increased. Drive slowly and use extreme caution when turning on hillsides.
Overturning the Implement could cause the Implement to overturn the Tractor and vice
versa resulting in serious injury or even death. Never fold wings on a hillside...the
Implement may overturn. (STI-02)
Operating Position
Ensure that the PTO Switch is in the OFF
position. With tractor engine running, pull LIFT
control lever rearward until wing is fully retracted
in and there is no tension on the transport link.
Take clip pin from the pin holding the transport
link and cylinder on the actuator. Once transport
link has been freed move transport link to the
welded holding bracket on the frame. Finally
slowly lower the wing down to the ground and
then engage the levers into the float position.
OPS-F-0046
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)
Do not put hands or feet under mower decks. Blade Contact can result
in serious injury or even death.
Stay away until all motion has
stopped and the decks are securely blocked up. (SFL-2)

OPERATION
Flail Mowers are capable under adverse conditions of throwing objects
for great distances (100 yards or more) and causing serious injury or
death. Follow safety messages carefully.
10.4 Driving the Tractor and Mower
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, especially when the
wings are lowered. OPS-F-0047
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-F-0048

Operation Section 4-27
OPERATION
Start off driving at a slow speed and gradually increase your speed while maintaining
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.

10.5 Crossing Ditches and Steep Inclines
When crossing ditches with steep banks or
going up sharp inclines, it is possible that the
main driveline inner profile will penetrate into
the outer housing to its maximum depth until the
assembly becomes solid (driveline is at its
extreme shortest length). This type of abusive
operation can cause serious damage to the
tractor and mower drive by pushing the PTO into
the tractor and through the support bearings or
downward onto the PTO shaft, breaking it off.
OPS-F-0049
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
GRASS KING 03/09
© 2009 Alamo Group Inc.
Operation Section 4-28
OPERATION
When confronted with an incline or ditch, do not
approach from an angle which is perpendicular
or straight on as damage to over collapse of the
driveline may occur.
When crossing such terrain, the wings should be
fully lowered for a lower center of gravity and
added stability.
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
as approach increases the possibility of a tractor
roll-over, select an alternate crossing path.
OPS-F-0050
CORRECT: Approach ditch at an angle.
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.

INCORRECT: DO NOT approach ditch straight on.
OPERATION
11. OPERATING THE TRACTOR AND MOWER
OPERATION
THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND MOWER
AND ALL CONTROLS BEFORE ATTEMPTING TO MOW. The operator must read and understand the Safety
and Operation Sections of the mower and tractor operator’s manuals. These manuals must be read and
explained to any operator who cannot read. Never allow someone to operate the mower and tractor without
complete operating instructions.
Before starting any mowing operation, the operator must become familiar with the area to be mowed 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.
Engage the PTO shaft at low engine RPM and speed the engine up after blades are fully engaged. Never
engage the PTO shaft at a high engine RPM. This could cause damage to the PTO shaft as well as the Speed
Increaser and Pump. Always operate PTO at the recommended RPM when mowing. This is necessary to
maintain proper blade speed and to produce a clean cut.
Proper ground speed for cutting will depend upon the height, type, and density of material to be cut. Normally,
ground speed will range from 2 to 5 mph. Tall dense material should be cut at low speed while thin medium
height material can be cut at a faster ground speed.
Always run the Mower at the highest position which will enable you to obtain the desired cutting results.
Allowing the blades to cut into the ground will cause wear and undue strain on the mower frame and mower
components.
If you are mowing in conditions of heavy growth or rough ground where the blades cut into the ground and the
tractor engine slows down, do not depress the clutch on the tractor to allow the engine to speed up and
engage the clutch again. This procedure exerts tremendous strain on Mower components. Always disengage
the PTO and move forward or backwards until the machine is clear.
This mower is designed with free swinging blades. This feature reduces the amount of shock transmitted to
other components. Always make sure the blades can swing freely.
Do not ride the clutch on the tractor. Mow in the appropriate gears to give the correct ground speed.
As often as possible, stop mowing when other people are passing by. Although the Mower is shielded to
prevent objects from being thrown out by the blades, no one shield device is 100% effective. The safest
possible course is the only sensible approach to the problem of endangering a passerby. The operator has
greater knowledge of the dangers of being around this Mower while it is operational than the person on the
street.
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)
GRASS KING 03/09
© 2009 Alamo Group Inc.
Operation Section 4-30
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)
Foreign Debris Hazard
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 motion to stop, then raise the mower
and move the tractor and mower 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 cuttershafts are balanced
before resuming operation. OPS-F-0052
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.
GRASS KING 03/09

Operation Section 4-31
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. OPS-F-0051
OPERATION
11.1 Bystander/Passersby Precautions
If a bystander comes within 100 yards 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 100 yard distance.
Flail Mowers are capable under adverse conditions of throwingobjects
for great distances (100 yards or more) and causing seriousinjury or
death. Follow safety messages carefully.
OPERATION
STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good,
workablecondition;
-Mower sections
or Wings are running close to and parallel to the ground
withoutexposed Blades;
-Passerby are outside the existing thrown-object zone;-All areas have been thoroughly
inspected and all foreign material such as rocks, cans, glass, and general debris has
been removed.
NOTE: Where there are grass and weeds high enough to hide debris that could
bestruck by the blades, the area should be: inspected and large debris removed, mowed
atan intermediate height, inspected, closely with any remaining debris being removed,
andmowed again at desired final height. (This will also reduce power required to
mow,reduce wear and tear on the Mower drivetrain, spread cut material better,
eliminatestreaking, and make the final cut more uniform.) (SFL-6)
11.2 Engaging the Power to Take Off (PTO)
Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The mower wings
must be completely lowered and the deck positioned at a safe mowing height. NEVER engage the PTO with
the mower wings 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 540 rpm. If you hear
unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the mower to
determine the cause of the noise or vibration and repair the abnormality.
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)
GRASS KING 03/09

Operation Section 4-32
OPERATION
12. 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. Mower is designed to mow
effectively when a cuttershaft speed of 2100 RPM is maintained. 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)
Operating the Mower
Only operate the mower from the tractor operator’s seat with the seatbelt securely fastened on a ROPS or cab
equipped tractor. The mower is designed for cutting grass and small weeds. Sharp blades will produce a
cleaner cut and require less power. Travel at a speed that allows the mower sufficient time to cut through the
vegetation and maintain the PTO operating speed to prevent overloading the mower and tractor. Choose a
driving pattern that provides the maximum pass length and minimizes turning. Stay alert and watch for trees,
low hanging limbs, power lines, and other overhead obstacles and solid ground objects while you are
operating.
Under some conditions, tractor tires may roll vegetation down preventing a cut at the same height as the
surrounding area. To minimize this problem, reduce the tractor ground speed while maintaining the operating
speed of the mower. A slower ground speed allows grasses to partially rebound and be cut. Reversing the
direction of travel may also help produce a cleaner cut in these conditions.
Avoid mowing in the reverse direction. If the mower must be backed to access an area to cut, make sure there
are no persons or other foreign debris behind the mower before mowing in reverse. When mowing in reverse,
operate the tractor and mower at a reduced ground speed to ensure control of the tractor and mower is
maintained.
Do not mow with two machines in the same area except with Cab tractors with the windows
closed. (SGM-11)
GRASS KING 03/09
© 2009 Alamo Group Inc.
Operation Section 4-33
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.
OPERATION
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)

13. DISCONNECTING THE MOWER FROM THE TRACTOR
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)
To disconnect the rear mower, first extend the
tractor 3-point hitch top link to remove tension on
the top link hitch pin. When the pin is loose and
easy to rotate, remove the pin from the mower.
Next remove both lower hitch pins. OPS-F-0055
After disconnecting the 3 lift points, remove the
mower driveline from the tractor PTO shaft. Lay
the driveline down carefully to avoid damaging the
driveline or its shield. Do not let the driveline fall
into mud or dirt, which can contaminate the
bearing and shorten the life of the driveline.
OPS-F-0056
Before disconnecting the mower, the PTO must be disengaged and all motion at a complete stop. Move the
mower to a level storage location and lower both wings to the ground. If the mower will be stored with the
sections in the raised position, be sure that the locks are engaged. If the mower is not resting securely on the
ground, block the mower up securely before attempting to disconnect it from the tractor. Use extreme care to
keep feet and hands from under the mower and clear of any pinch points.

14. MOWER STORAGE
It is recommended that the mower be stored lowered to ground level. If the mower is stored in the raised
position, select a level area and ensure the wing is locked to prevent unexpected falling BEFORE
disconnecting the mower 3-point hitch and hydraulics 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:
Thoroughly clean all debris off the mower to prevent damage from rotting grass and standing water.
Lubricate all mower grease points and fill hydraulic tank oil level 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.
5. Store the mower in a clean, dry place with the mower housing resting securely on blocks or at ground level.
6. Keep the driveline yoke from sitting in water, dirt and other contaminants.
7. Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the mower.
It is critical that the driveline clutch 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 Clutch Maintenance
section of this manual.
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)
15. TRANSPORTING THE TRACTOR AND MOWER
Inherent dangers of operating the tractor and mower and the possibility of accidents are not left behind when
you finish mowing an area. Therefore, the operator must use good judgement and safe operation practices
when transporting the tractor and mower between locations. By using good judgement and following safe
transport procedures, the possibility of accidents while moving between locations can be substantially
minimized.
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. Raise the mower section and
ensure transport lock is engage. OPS-F-0057
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
mower at speeds greater than 20 MPH.
OPS-F-0058
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.

15.1 Transporting on Public Roadways
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)
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)
Use extreme caution 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 you are towing is wider than the tractor tire width and/or
extends beyond your lane of the road.
A safety tow chain rated for the weight of the mower must be secured between the tractor and mower before
entering a public road. Ensure that the mower sections are fully raised and that the transport locks are
engaged for each section.
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 mower on a public
roadway. Replace the SMV emblem if faded,
damaged, or no longer reflective. OPS-F-0059

While newer model tractors have plenty of
lighting to provide warning signals and operating
lighting, most older models were only equipped
with operating lights. Consult an authorized
tractor dealer for lighting kits and modifications
available to upgrade the lighting on older tractor
models.
When operating on public roads, have
consideration for other road users. Pull to the
side of the road occasionally to allow following
traffic to pass. Do not exceed the legal speed
limit set in your area for agricultural tractors.
Always stay alert when transporting the tractor
and mower on public roads. Use caution and
reduce speed if other vehicles or pedestrians are
in the area.

HYDRAULIC OIL, FILTERS, & COMPONENTS
Filters and Oil - Change the return filter in the tank after the first 200 hours of operation. Change the filters
again at 800 hours; then, change the oil and filters at 1600 hours. After that, continue to change the filter every
800 hours and the oil every 1600 hours. Hydraulic oil to be Chevron 1000 THF or equivalent. Use SAE 90 wt.
in Speed Increaser. Use the above procedures as part of a good filter maintenance program.
Note: Your ambient temperature and operating conditions may require a different viscosity oil. Please consult
the oil manufacturer for proper specifications.
The reservoir stores hydraulic system oil. The breather cap which is mounted on top of the reservoir prevents
an extreme pressure buildup or vacuum from occurring in the tank as oil level changes. There is also an oil
filler cap which is used to fill the reservoir with oil. To help prevent dirt from entering the tank, clean the top of
the reservoir before removing the cap. THE BREATHER CAP HOLDS APPROX 11 PSI PRESSURE IN TANK.
REMOVE FILLER CAP SLOWLY
The oil level sight glass is located on the back of the reservoir. The oil level should be even with the sight glass
and checked with the cutter unit in the transport position. The oil temperature should not exceed 180 degree F.
The oil return hoses are connected to the hydraulic filter on top of the reservoir. Oil is returned from cutter unit
cooling tubes and filtered before entering the hydraulic reservoir. Oil returning from the control circuit also
enters the reservoir through the filter.
PROPER OIL LEVEL
Maintain the oil level within the sight gauge located on the side of the reservoir. Never fill the tank above the
sight gauge level. A space is maintained above the sight gauge to allow for the expansion of the oil. The tank
maintains pressure after the mower has been run. Stand off to one side when removing the breather cap
element to prevent possible injury. To relieve pressure, remove the breather cap element and depress the
spring loaded pressure valve to release any excess air. Fill with Universal Tractor Hydraulic Oil.

Cylinder Rod Maintenance
It is important to visually inspect the hydraulic cylinder rods daily before use. It is highly recommended that
while the machine is stored or getting very little use that a protectant is applied to the hydraulic cylinder rods to
prevent degradation. If the machine receives more frequent use, be sure to fully cycle each cylinder function so
that the cylinder rod is coated by the systems hydraulic fluid. Depending on your operating environment it may
be necessary, under normal operating conditions, to apply a protective lubricant to the cylinder rods for protection against rust and pitting. Hydraulic fluid may provide a suitable amount of protection, but remember any
protectant can attract dust and debris so attention must be given to the cylinder rods daily. Also remember that
any other protectant must be compatible with hydraulic fluid. Alamo Industrial is not responsible for rust or pitting of the cylinder rod due to weather exposure or impacts from normal operation or mounting. If hydraulic cylinders and or the cylinder rods are damaged as a result of the rods rusting or pitting, the hydraulic cylinders
and rods will not be covered under warranty by Alamo Industrial.

SPINDLE SERVICE PROCEDURE (Cont’d)
1. Using a 3/16” cape chisel, bend out the staking indentations on each side of the bearing adjusting nut. To
do this, place the chisel in the groove and parallel to the shaft. Drive the chisel downward until the
indentation is free of the shaft and threads (see Figure 1).
2. Using the same chisel, straighten the tang on the lockwasher (if equipped with a lockwasher).
NOTE: The lockwasher will not be installed during assembly if the spindle uses the staked adjusting nut.
3. Remove bearing adjusting nut and lockwasher (if equipped). Discard these parts. They are not reusable.
Install a new adjusting nut when assembling.
4. Screw the original blade bar bolts into the flange of the spindle shaft until they contact the bearing ring (see
Figure 2).
5. In a clockwise pattern, rotate each bolt 1/4 turn (see Figure 3). Continue turning the bolts 1/4 turn at a time
(maximum of 3 turns), until the special shanked bolts (P/N 02964353) will thread into the spindle.
6. Remove the original bolts and replace them with the shanked bolts. Screw the shanked bolts in until they
contact the bearing ring.
7. In a clockwise pattern, rotate the bolts 1/4 turn at a time until the spindle is free from the housing.
8. Remove the seal retaining ring from the housing using a flat screwdriver or similar tool.
9. Remove the seal and bearing.
10. A punch or similar tool can be used to remove the bearing cups from the housing if the cups are not to be
re-used.
CLEANING
1. Clean housing and all related parts thoroughly and dry.
2. Protect parts from contamination.
INSPECTION
BEARINGS AND CUPS: Inspect rollers, races and cages for nicks, pitting, discoloration, and signs of excessive or unusual wear. Replace any worn or damaged parts.
SPINDLE SHAFT: Inspect the threads, internal splines and bearing journals for damage or wear. Replace if
damaged or worn.
BEARING RING: Inspect the ring for wear in the area of seal contact. Replace if a wear groove exists.
HOUSING: Inspect the bearing cup bores, ring grooves, etc. for wear or damage. Repair or replace if any
damage is found.
ASSEMBLY
Tools needed:
Hand tools
Hydraulic press
Inch pound torque wrench
Seal Installers
Bearing drivers (do not use punches
Adjusting nut socket
to install bearings)
2-3/4" ID x 8" long, 16 Ga. tubing
NOTE: This procedure should not be attempted in the field due to the need for tools normally only found
in the shop.
1. Place upper bearing cones in bearing oven.
2. Seat bearing cups (outer races) in housing using a press and proper installation tools in good
condition.CUPS MUST BE FULLY SEATED. If bearing cup cocks in bore and seizes, do not continue to
assemble spindle.
3. Lubricate lower bearing cone with LPS.

Coat the outside of the seal with silicone and install the lower bearing, seal, and retaining ring into the
housing, using the correct seal installer.
2. Place a light film of silicon or permatex on the inside diameter of the bearing ring and seat the ring on the
spindle shaft, using the proper tool and press.
3. Lightly lubricate the lip of the seal.
4. Using the 2-3/4" tubing to prevent the cup and cone from contacting each other, press the spindle shaft
through the lower bearing and seal. Make sure the bearing is seated against the bearing ring.
5. Place loctite on threads of the bearing adjusting nut (flange nut).
6. Using gloves, install the heated upper bearing cone on the shaft immediately and push it all the way
against the cup. Lubricate the bearing with LPS.
7. Install the bearing adjusting nut. Tighten the nut until the spindle shaft can not be turned. Loosen the nut
1/4 turn. Place a soft, clean cloth over the top of the spindle assembly. Place an aluminum block over the
end of the spindle shaft and strike the block with a hammer to loosen the bearing.
8. Remove the cloth, being careful not to allow any contamination into the spindle. Tighten the nut until a
rolling torque of 16-21 inch-pounds is reached. (If the seal was not lubricated, add 10 inch-pounds).
9. Stake the nut with a blunt, round nosed punch. Do not tear the nut.
10. Insert the lubricant nozzle into the hole in the center of the housing (between the bearings) and fill the
housing with 000 grease (P/N 00765444), stopping when the lubricant covers the upper bearing
(approximately 11 oz.).
11. Install the breather plug in the top hole (if there is a top hole), and the solid plug in the fill hole. If only one
hole exists, put the breather plug in it.
12. Install spindle in mower deck and assemble in reverse order. Torque the blade bar or pan bolts to
400 ft.-lbs. Torque motor to spindle bolts to 85 ft.-lbs. Torque spindle to deck bolts at 175 ft.-lbs.
