Form in full and return it to within 30 Days. Make certain the Serial Number of the Machine is recorded on the War­ranty Card and on the Warranty Form that you retain.

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 Indus-
trial.

If you would like a VHS video tape of the video, please email [e-mail] or Fax
AEM VHS Video at [phone] 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.

Every operator should be trained for each piece of equipment (Tractor and Mower), understand the

Operator Safety Instructions and Practices

The rotating parts of this machine continue to rotate even after the PTO has been turned off.
The operator should remain in his seat for 60 seconds after the brake has been set, the

PTO disengaged, the tractor turned off, and all evidence of rotation has ceased.

“Wait a minute...Save a life!”

Never crawl under a raised Implement supported solely by the Tractor 3-Point hitch.
Release of the control lever or mechanical failure will result in the Implement falling and
possible injury or death. Always securely block up the Implement before crawling
underneath to perform repairs and service.

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-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.

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.

SAFETY

Never allow children to operate, ride on, or come close to the Tractor or
Implement. Usually, 16-17 year-old children who are mature and
responsible can operate the implement with adult supervision, if they
have read and understand the Operator’s Manuals, been trained in
proper operation of the tractor and Implement, and are physically large
enough to reach and operate the controls easily.

Do not mount the Tractor while the tractor is moving. Mount the Tractor
only when the Tractor and all moving parts are completely stopped.

Start tractor only when properly seated in the Tractor seat. Starting a
tractor in gear can result in injury or death. Read the Tractor operators
manual for proper starting instructions.

(SG-12)

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.

discontinue mowing.

(SGM-1)

There are obvious and hidden potential hazards in the operation of this

Mower. REMEMBER! This machine is often operated in heavy brush
and in heavy weeds. The Blades of this Mower can throw objects if shields are not
properly installed and maintained. Serious injury or even death may occur unless care is
taken to insure the safety of the operator, bystanders, or passersby in the area. Do not
operate this machine with anyone in the immediate area. Stop mowing if anyone is within
100 yards of mower.

(SGM-2)

(SG-39)

The rotating parts of this machine have been designed and tested for rugged use.
However, the blades could fail upon impact with heavy, solid objects such as metal guard
rails and concrete structures. Such impact could cause the broken objects to be thrown
outward at very high velocities. To reduce the possibility of property damage, serious
injury, or even death, never allow the cutting blades to contact such obstacles.

reme care should be taken when operating near loose objects suc

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.

Never allow the cutting blades to contact such items.

ow 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-7)

Avoid mowing in reverse direction when possible. Check to make sure there are no
persons behind the mower and use extreme care when mowing in reverse. Mow only at a
slow ground speed where you can safely operate and control the tractor and mower.
Never mow an area that you have not inspected and removed debris or foreign material.

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.

SAFETY

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.

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.

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;

SAFETY

-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-1)

(SGM-15)

(SPU-1)

Do not turn so sharp or lift mower so high to produce a severe "knocking" of the Driveline
which will cause accelerated wear and breakage of drive train components and could result

in possible injury from the separated Driveline sections.

Do not let the Blades turn when the Mower Deck is raised for any

reason, including clearance or for turning. Raising the Mower deck
exposes the Cutting Blades which creates a potentially serious hazard and could cause
serious injury or even death from objects thrown from the Blades.

Connecting or Disconnecting Implement Safety Instructions and Practices

DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor

PTO. Use of an adapter can double the operating speed of the Implement resulting in
excessive vibration, thrown objects, and blade and implement failure. Adapter use will also
change the working length of the driveline exposing unshielded driveline areas. Serious
bodily injury and/or equipment failure can result from using a PTO adapter. Consult an
authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.

(S3PT-14)

Always shut the Tractor completely down, place the transmission in park, and set the

parking brake before you or anyone else attempts to connect or disconnect the Implement

and Tractor hitches.

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-15)

(S3PT-16)

SAFETY

en attaching the Implement input driveline to the Tractor
connecting yoke spring activated locking collar slides freely and the locking balls are seated
securely in the groove on the Tractor PTO shaft. A driveline not attached correctly to the
Tractor PTO shaft could come loose and result in personal injury and damage to the
Implement.

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.

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 fron
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 tracto
and/or Implement and possibly cause the operator or others to be injured or killed. (S3PT-2)

B

Allow sufficient clearance for the Implement to swing outward while turning. Implements
carried behind the Tractor will swing outside the tire path when making turns. Contacting a
solid object while turning will cause equipment damage and possible injury.

Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in
such a way as to be clearly visible and legible. When transporting the
Equipment use the Tractor flashing warning lights and follow all local
traffic regulations.

Transport only at 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

SAFETY

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.

(SG-6)

(S3PT-20)

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)

e 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.

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.
