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 oper-

ation of their mowing equipment and be able to recognize the potential hazards that can occur while oper-

ating 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 [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.

SAFETY

General Safety Instructions and Practices

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)

READ, UNDERSTAND, and FOLLOW the following Safety Messages. Serious injury or

death may occur unless care is taken to follow the warnings and instructions stated in the

Safety Messages. Always use good common sense to avoid hazards. ^(SG-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)

Operator Safety Instructions and Practices

The rotating parts of this machine continue to rotate even after the PTO has been turned off.

The operator should remain in his seat for 60 seconds after the brake has been set, the

PTO disengaged, the tractor turned off, and all evidence of rotation has ceased. ^(S3PT-10)

“Wait a minute...Save a life!”

Never crawl under a raised Implement supported solely by the Tractor 3-Point hitch.

Release of the control lever or mechanical failure will result in the Implement falling and

possible injury or death. Always securely block up the Implement before crawling

underneath to perform repairs and service. ^(S3PT-19)

Never operate the Tractor or Implement until you have read and

completely understand this Manual, the Tractor Operator’s Manual, and

each of the Safety Messages found in the Manual or on the Tractor and

Implement. Learn how to stop the tractor engine suddenly in an

emergency.

Never allow inexperienced or untrained personnel to

operate the Tractor and Implement without supervision. Make sure the

operator has fully read and understood the manuals prior to operation.

(SG-4)

The operator and all support personnel should wear hard hats, safety

shoes, safety glasses, and proper hearing protection at all times for

protection from injury including injury from items that may be thrown by

the equipment. ^(SG-16)

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)

SAFETY

Always read carefully and comply fully with the manufacturer’s

instructions when handling oil, solvents, cleansers, and any other

chemical agent. ^(SG-22)

KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement

and possible serious injury or death. ^(SG-24)

Never allow children to play on or around Tractor or Implement. Children can slip or fall off

the Equipment and be injured or killed. Children can cause the Implement to shift or fall

crushing themselves or others. ^(SG-25)

NEVER use drugs or alcohol immediately before or while operating the

Tractor and Implement.

alertness and coordination and therefore affect the operator’s ability to

operate the equipment safely. Before operating the Tractor or

Drugs and alcohol will affect an operator’s

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

gound 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)

SAFETY

DO NOT operate this Implement on a Tractor that is not properly maintained. Should a

mechanical or Tractor control failure occur while operating, immediately shut down the

Tractor and perform repairs before resuming operation. Serious injury and possible death

could occur from not maintaining this Implement and Tractor in good operating condition.

(SG-36)

Avoid contact with hot surfaces of the engine or muffler. Use gloves and eye protection

when servicing hot components. Contact with a hot surface or fluid can cause serious injury

from burns or scalding. ^(SG-38)

Do not put hands or feet under mower decks. Blade Contact can result

in serious injury or even death. Stay away until all motion has stopped

and the decks are securely blocked up. ^(SGM-9)

Always keep a careful lookout and use extreme care when working around utility and

municipal obstructions. Never allow the Mower to contact any utility, municipal, or other

type structure. Clearly mark all mowing obstructions and consult local utility providers for a safe code of

operation. ^(SPU-5)

Do not operate the implement while wearing loose fitting clothing. Entanglement of the

clothing with the rotating elements can result in serious injury or even death. Stay clear of

all rotating elements at all times. (SSP-3)

Equipment Operation Safety Instructions and Practices

Never leave the Tractor and Implement unattended while the Implement is in the lifted

position. Accidental operation of lifting lever or a hydraulic failure may cause sudden drop

of unit with injury or death by crushing. To properly park the implement when disconnecting it from the tractor,

lower the stand and put the retaining pin securely in place, or put a secure support under the 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-5)

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)

A60/A72 01/08

Safety Section 1-5

Download from Www.Somanuals.com. All Manuals Search And Download.

SAFETY

Be sure you have adequate knowledge of the property you will be working on. Take time to

make yourself aware of any area underground lines or cables. Contact with buried lines or

cable could result in serious injury or death. If in doubt about buried utility lines call 811

before digging or 1-800-258-0808. ^(SBH-6)

Do not operate Mower if excessive vibration exists.

Shut down PTO and the Tractor

engine. Inspect the Mower to determine the source of the vibration. If Mower blades are

missing or damaged replace them immediately.

Do not operate the mower until the blades have been

replaced and the Mower operates smoothly. Operating the Mower with excessive vibration can result in

component failure and broken objects to be thrown outward at very high velocities. To reduce the possibility of

property damage, serious injury, or even death, never allow the Mower to be operated with blades missing.

(SFL-4)

Operate this Equipment only with a Tractor equipped with an approved roll-

over-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 the Tractor while the tractor is moving. Mount the Tractor

only when the Tractor and all moving parts are completely stopped. ^(SG-12)

A60/A72 01/08

Safety Section 1-6

SAFETY

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)

Do not operate this Equipment with hydraulic oil or fuel leaking. Oil and

fuel are explosive and their presence could present a hazard. Do not

check for leaks with your hand! High-pressure oil streams from breaks in

the line could penetrate the skin and cause tissue damage including

gangrene. To check for a hose leak, SHUT the unit ENGINE OFF and

remove all hydraulic pressure. Wear oil impenetrable gloves, safety

glasses and use Cardboard to check for evidence of oil leaks. If you

suspect a leak, REMOVE the HOSE and have it tested at a Dealer. If oil

does penetrate the skin, have the injury treated immediately by a

physician knowledgeable and skilled in this procedure. (SG-15)

Never run the Tractor engine in a closed building or without adequate ventilation. The

exhaust fumes can be hazardous to your health. ^(SG-23)

Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause

Implement driveline or blade failures resulting in serious injury or death. ^(SG-26)

Operate the Tractor and/or Implement controls only while properly seated in the Tractor seat

with the seat belt securely fastened around you. Inadvertent movement of the Tractor or

Implement may cause serious injury or death. ^(SG-29)

In case of mechanical difficulty during operation, place the transmission in the park

position, set the parking brake, shut down all power, including the PTO and the engine and

remove the key. Wait until all rotating motion has stopped before dismounting. ^(SG-39)

Do Not operate this equipment in areas where insects such as bees may attack you and/or

cause you to lose control of the equipment. If you must enter in such areas, use a tractor

with an enclosed Cab and close the windows to prevent insects from entering. If a tractor

cab is not available, wear suitable clothing including head, face, and hand protection to

shield you from the insects. Attacking insects can cause you to lose control of the tractor,

which can result in serious injury or death to you or bystanders. Never dismount a moving

tractor. (SG-40)

SAFETY

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)

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

Mower. REMEMBER! This machine is often operated in heavy brush

and in heavy weeds. The Blades of this Mower can throw objects if shields are not

properly installed and maintained. Serious injury or even death may occur unless care is

taken to insure the safety of the operator, bystanders, or passersby in the area. Do not

operate this machine with anyone in the immediate area. Stop mowing if anyone is within

100 yards of mower. ^(SGM-2)

The rotating parts of this machine have been designed and tested for rugged use.

However, the blades could fail upon impact with heavy, solid objects such as metal guard

rails and concrete structures. Such impact could cause the broken objects to be thrown

outward at very high velocities. To reduce the possibility of property damage, serious

injury, or even death, never allow the cutting blades to contact such obstacles. ^(SGM-4)

Extreme care should be taken when operating near loose objects such

as gravel, rocks, wire, and other debris. Inspect the area before

mowing. Foreign objects should be removed from the site to prevent machine damage

and/or bodily injury or even death. Any objects that cannot be removed must be clearly

marked and carefully avoided by the operator. Stop mowing immediately if blades strike a

foreign object. Repair all damage and make certain rotor or blade carrier is balanced

before resuming mowing. ^(SGM-5)

Many varied objects, such as wire, cable, rope, or chains, can become entangled in the

operating parts of the mower head. These items could then swing outside the housing at

greater velocities than the blades. Such a situation is extremely hazardous and could result in serious injury

or even death. Inspect the cutting area for such objects before mowing. Remove any like object from the site.

Never allow the cutting blades to contact such items. ^(SGM-6)

Mow at the speed that you can safely operate and control the tractor and mower. 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)

A60/A72 01/08

Safety Section 1-8

SAFETY

Avoid mowing in reverse direction when possible. Check to make sure there are no

persons behind the mower and use extreme care when mowing in reverse. Mow only at a

slow ground speed where you can safely operate and control the tractor and mower.

Never mow an area that you have not inspected and removed debris or foreign material.

(SGM-8)

Do not mow with two machines in the same area except with Cab tractors with the windows

closed. ^(SGM-11)

Follow these guidelines to reduce the risk of equipment and grass fires

while operating, servicing, and repairing the Mower and Tractor:

-Equip the Tractor with a fire extinguisher in an accesible location.

-Do Not operate the Mower on a Tractor with an underframe exhaust.

-Do Not smoke or have an open flame near the Mower and Tractor.

-Do Not drive into burning debris or freshly burnt areas.

-Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating.

-Never allow clippings or debris to collect near drivelines, slip clutches, and gearboxes.

Periodically shut down the Tractor and Mower and clean clippings and collected debris from

the mower deck. ^(SGM-12)

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 non-vegetative material. Only

operate this Mower on a properly sized and equipped Tractor. Operating this Mower in an application for

which it is not designed and/or operating the Mower with the wrong size Tractor can cause Mower component

damage and equipment failure resulting in possible serious injury or death. ^(SGM-14)

Do not operate or pull the mower into standing water. When uplift or fan type mower blades

contact water they can be severely deflected downward causing possible failure of blade

resulting in serious boldly injury to the operator or bystanders. (SGM-15)

Use extreme caution when raising the Mower above ground level. Stop the Blades from

turning when the Mower is raised and passersby are within 100 yards. Raising the

Mower exposes the Cutting Blades which creates a potentially serious hazard and can cause serious injury

by objects thrown from the Blades or by contact with the Blades. ^(SPU-1)

A60/A72 01/08

Safety Section 1-9

Download from Www.Somanuals.com. All Manuals Search And Download.

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-1)

Do Not attempt to raise or lower the implement wing unless the Implement tongue is

securely attached to the Tractor drawbar. The Implement could tip over and cause

equipment damage and possible serious injury or death. Raise or Lower the mower wing

only while seated in the Tractor operator’s seat with the seat belt securely fastened. ^(SRM-2)

Do not turn so sharp or lift mower so high to produce a severe "knocking" of the Driveline

which will cause accelerated wear and breakage of drive train components and could result

in possible injury from the separated Driveline sections. ^(SRM-4)

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

reason, including clearance or for turning. Raising the Mower deck

exposes the Cutting Blades which creates a potentially serious hazard and could cause

serious injury or even death from objects thrown from the Blades. ^(SRM-7)

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)

A60/A72 01/08

Safety Section 1-10

Download from Www.Somanuals.com. All Manuals Search And Download.

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)

When attaching the Implement input driveline to the Tractor PTO, it is important that the

connecting yoke spring activated locking collar slides freely and the locking balls are seated

securely in the groove on the Tractor PTO shaft. A driveline not attached correctly to the

Tractor PTO shaft could come loose and result in personal injury and damage to the

Implement. ^(S3PT-17)

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-2)

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

Transport only at speeds where you can maintain control of the

equipment. Serious accidents and injuries can result from operating this

equipment at high speeds. Understand the Tractor and Implement and how it handles

before transporting on streets and highways. Make sure the Tractor steering and brakes

are in good condition and operate properly.

Before transporting the Tractor and Implement, determine the proper transport speeds for

you and the equipment. Make sure you abide by the following rules:

•

Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes

smoothly to determine the stopping characteristics of the Tractor and Imple-

ment. 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-1)

Only transport the Implement behind a properly sized and equipped

Tractor which exceeds the weight of the Implement by at least 20%. DO

NOT transport the Implement behind a truck or other type of vehicle.

Never transport the Implement and another Implement connected in

tandem. Never transport the Implement at speeds over 20 MPH. ^(STI-6)

SAFETY

Your driving vision may be reduced or impaired by the tractor, cab, or implement. Before

driving on public roadways identify any limited vision areas, and make adjustments to your

operating position, mirrors, and the implement transport position so that you can clearly

see the area where you will be traveling, and any traffic that may approach you. Failure to

maintain adequate vision of the public roadway and traffic can result in serious injury or

even death. ^(STI-10)

Maintenance and Service Safety Instructions and Practices

Make sure the PTO shield, integral driveline shields, and input shields

are is installed when using PTO-driven equipment. Always replace any

shield if it is damaged or missing. ^(S3PT-8)

Relieve hydraulic pressure prior to doing any maintenance or repair work

on the Implement. Place the Implement on the ground or securely

blocked up, disengage the PTO, and turn off the tractor engine. Push

and pull the Remote Cylinder lever in and out several times prior to

starting any maintenance or repair work. ^(S3PT-9)

Always disconnect the main PTO Driveline from the Tractor before performing service on

the Implement. Never work on the Implement with the tractor PTO driveline connected and

running. Rotating Parts, Blades or Drivelines could turn without warning and cause

immediate entanglement, injury or death. ^(S3PT-11)

Never interfere with factory-set hydraulic calibrations. Any change in calibration could

cause a failure of the equipment and may result in injury. (SBH-13)

Always maintain the safety signs in good readable condition. If the safety signs are

missing, damaged, or unreadable, obtain and install replacement safety signs immediately.

(SG-5)

Do not modify or alter this Implement. Do not permit anyone to modify or alter this

Implement, any of its components or any Implement function. (SG-8)

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)

SAFETY

Never attempt to lubricate, adjust, or remove material from the Implement while it is in

motion or while tractor engine is running. ^(SG-20)

Periodically inspect all moving parts for wear and replace when

necessary with authorized service parts. Look for loose fasteners, worn

or broken parts, and leaky or loose fittings. Make sure all pins have

cotter pins and washers. Serious injury may occur from not maintaining

this machine in good working order. ^(SG-21)

Do Not fill gasoline tank while engine is running. Refuel only after engine has cooled down.

If gasoline is spilled, move machine away from the area of the spill and avoid creating any

source of ignition until the gasoline has evaporated. ^(SG-28)

Perform service, repairs and lubrication according to the maintenance section. Ensure the

unit is properly lubricated as specified in the lubrication schedule and all bolts and nuts are

properly torqued. Failure to properly service, repair and maintain this Implement in good

operating condition could cause component failure and possible serious injury or even

death. ^(SG-35)

Use caution and wear protective gloves when handling sharp objects such as blades,

knives, and other cutting edges. Be alert to worn component surfaces which have sharp

edges. Sharp surfaces can inflict severe laceration injuries if proper hand protection is not

worn. ^(SG-37)

All Safety Shields, Guards and Safety devices including (but not

limited to) - the Deflectors, Chain Guards, Steel Guards, Gearbox

Shields, PTO integral shields, and Retractable Door Shields should be used and

maintained in good working condition. All safety devices should be inspected

carefully at least daily for missing or broken components. Missing, broken, or worn

items must be replaced at once to reduce the possibility of injury or death from thrown

objects, entanglement, or blade contact. ^(SGM-3)

Replace bent or broken blades with new blades. NEVER ATTEMPT TO STRAIGHTEN,

WELD, OR WELD HARDFACING ON BLADES SINCE THIS WILL LIKELY CRACK OR

OTHERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLE

SERIOUS INJURY FROM THROWN BLADES. ^(SGM-10)

INTRODUCTION

These mowers are available in lift-type models only. These rugged Mowers are designed for heavy-duty work.

They can mow pastures, cut brush up to 3" in diameter, and control grass and weeds on highways or industrial

sites.

For Non-Agricultural use, OSHA, ASAE, SAE, and ANSI standards require the use of Chain

Guards or Solid Skirts at all times. The Cutter manufacturer strongly recommends the use

of Chain Guards or Solid Skirts for Agricultural purposes as well, to reduce the risk of

property damage, serious bodily injury, or even death from objects thrown out by or from

contact with the Cutting Blades.

The A60 requires a tractor with a minimum of 30 HP and the A72 requires a minimum of 40 HP with adequate

front end weight.

At least 20% or the tractor’s weight must be on the front tires with the implement lifted to

provide adequate traction for safe steering under good conditions. Slow down on hills,

rough terrain, and curves.

Front and rear, and left and right are determined by the normal direction of travel (the same as on your

automobile).

ASSEMBLY

Check Chains - Extra Equipment - for Lift-Models

Check Chains are available for attachment to front of Mower as an accessory. (Figure Asm-0092) Check

chains are used to control cutting height and especially allow Mower to be lowered to the same preset cutting

height effortlessly.

Install lower end of check chain (4) to hitch ears (6) through lower holes (7) using bolts, nuts and

lockwashers(8). Tighten securely.

Install chain lugs (3) on either side of tractor top link mounting (5) using bolt or pin of required diameter and

length. Cat I kit requires a 3/4" diameter bolt. Cat II kit requires a 1" diameter bolt. Install top end of check

chains in brackets (3).

Cutting height is then set by placing proper chain link in keyhole slot. Cutting height is easily adjustable by

hooking chain higher or lower in the keyholes in chain lug (3).

For additional safety in transport, raise mower as high as possible without having driveline

hit deck and shorten check chains as much as possible to prevent inadvertent falling in

transport.

ASSEMBLY

Offset Adapter Hitch - Extra Equipment

1. Fasten the Offset Adapter Hitch weldment to

the lift lugs using the Hitch Pin holes. Fasten

the Adjustable Leg to the left side lug if the

Mower is to offset to the left. The Mower will

make a cleaner cut behind the wheel tracks if it

is offset to the left. Reverse the Assembly for

right offset (Figure Asm-0010).

2. Install the Brace Bars. Fasten the chain end to

the rear mounting hole in the Gearbox Base

Plate. Adjust the Brace Bar so the Hitch

Assembly is nearly perpendicular.

3. Attach the Mower to the tractor. Install stabilizer

bars or adjust sway chains to prevent side sway

of the mower.

Stabilizer Bars or Sway Chains must be installed and adjusted tightly. Without these bars

or chains, serious damage to the Driveline can occur, and broken parts could cause bodily

injury to the operator or bystanders. Stabilizer Bars or Sway Chains are available at most

tractor dealerships.

4. Raise the mower to check clearance between the Driveline and Mower Deck. Set the lift stop on the

tractor to ascertain that the Driveline does not strike the deck.

For additional safety in transport, raise mower as high as possible without having driveline

hit deck and shorten check chains as much as possible to prevent inadvertent falling in

transport.

OPERATION

A60/72 HEAVY-DUTY ROTARY MOWER

OPERATION INSTRUCTIONS

Alamo 60 and Alamo 72 (A60/72) rotary mowers are manufactured with quality material by skilled workers.

These heavy-duty mowers are engineered for mowing grass, shredding stalks, maintaining pastures, and

cutting other vegetation up to 3” in diameter. The mower is equipped with protective deflectors and/or 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

directly in front or to the rear of the unit.
