In order to reduce accidents and enhance the safe operation of mowers, Alamo Group Ag Division, in

cooperation with other industry manufacturers has developed the AEM/FEMA Industrial and

Agricultural Mower Safety Practices video and guide book.

The video will familiarize and instruct mower-tractor operators in safe practices when using industrial

and agricultural mowing equipment. It is important that Every Mower Operator be educated in the

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

operating a mower. This video, along with the mower operator’s manual and the warning messages on the

mower, will significantly assist in this important education.

Your Authorized Alamo Ag Dealer may have shown this video and presented you a DVD Video when you

purchased your mower. If you or any mower operator have not seen this video, Watch the Video, Read

this Operator’s Manual, and Complete the Video Guidebook before operating your new mower. If you

do not understand any of the instructions included in the video or operator’s manual or if you have any

questions concerning safety of operation, contact your supervisor, dealer or Alamo Group Ag.

Safety Messages

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.

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)

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.

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)

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)

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)

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)

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)

SAFETY

CY84 03/08 Safety Section 1-4

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. (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)

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)

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)

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

ety

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

CY84 03/08 Safety Section 1-5

SAFETY

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)

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

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

Transport only at speeds where you can maintain control of the

equipment. Serious accidents and injuries can result from operating this

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

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

are in good condition and operate properly.

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

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

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

to determine the stopping characteristics of the Tractor and Implement. As you increase

the speed of the Tractor the stopping distance increases. Determine the maximum

transport speed not to exceed 20 mph (30 kph) for transporting this equipment.

Test the equipment at a slow speed in turns. Increase the speed through the turn only after

you determine that the equipment can be operated at a higher speed. Use extreme care

and reduce your speed when turning sharply to prevent the tractor and implement from

turning over. Determine the maximum turning speed for you and this equipment before

operating on roads or uneven ground.

Only transport the Tractor and Implement at the speeds which allow you to properly control

the equipment.

Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes

or worn tires. When operating down a hill or on wet or rain slick roads, the braking distance

increases: use extreme care and reduce your speed. When operating in traffic always use

the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you

and watch out for the other guy. (SG-19)

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

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

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)

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)

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)

Mow only in conditions where you have clear visibility in daylight or with adequate arti

icial

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

CY84 03/08 Safety Section 1-7

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-2)

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)

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)

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)

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)

SAFETY

CY84 03/08 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 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)

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)

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)

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)

SAFETY

CY84 03/08 Safety Section 1-9

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)

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)

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

power-driven or pulled equipment. REMEMBER! This machine is often operated in rough

terrain conditions that include tall grass, weeds, gullies, holes, slopes, hidden obstructions

and the like. Serious injury or even death may occur unless care is taken to assure the

safety of the operator and bystanders in the area. Do not operate this machine with anyone

in the immediate area. (S3PT-7)

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)

SAFETY

CY84 03/08 Safety Section 1-10

SAFETY

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)

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!”

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)

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)

INTRODUCTION

This Rotary Mower is designed with care and built with quality materials by skilled workers. Proper assembly,

maintenance, and operating practices, as described in this manual, will help the owner/operator get years of

satisfactory service from the machine.

The purpose of this manual is to familiarize, instruct, and train. The Assembly Section instructs the owner/

operator in the correct assembly of the Mower using standard and optional equipment. The Parts Listing

section is designed to familiarize the owner/operator with replaceable parts on the Mower. This section

provides exploded assembly drawings of each mower component illustrating each piece and the

corresponding part number.

Careful use and timely service save extensive repairs and costly downtime losses. The Operation and

Maintenance Sections of the manual train the owner/operator how to work the Mower correctly and attend to

appropriate maintenance. The Trouble Shooting Guide helps diagnose difficulties with mower and offers

solution to the problems.

Safety is of primary importance to the owner/operator and to the manufacturer. The first section of this manual

includes a list of Safety Messages, that, if followed, will help protect the operator and bystanders from injury or

death. Many of the Safety Messages will be repeated throughout the manual. The owner/operator/dealer

should know these Safety Messages before assembly and be aware of the hazards of operating this blade

during assembly, use, and maintenance. The Safety Alert Symbol combined with a Signal Word, as seen

below, is intended to warn the owner/operator of impending hazards and the degree of possible injury faced

when operating this machine.

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.

CY84 03/08 Introduction Section 2-3

INTRODUCTION

Pull-Type Model

These mowers are available in lift-type and pull-type. These rugged Mowers are designed for medium-duty

work. They can mow pastures, cut brush up to 4" 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 84" Lift-Type machine requires a minimum of 60 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).

It is the operator’s responsibility to be knowledgeable of all 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.

This section 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 rotary mower and are not necessarily of a CY84 mower. Some pictures may show shields removed for

purposes of clarity. NEVER OPERATE this implement without all shields in place and in good operational

condition. The operator must be familiar with the mower and tractor operation and all associated safety

practices before operating the mower and tractor. Proper operation of the CY84 mower, as detailed in this

manual, will help ensure years of safe and satisfactory use of the mower.

IMPORTANT: To avoid damage to the cutter, retorque all bolts after the first 10 hours of operation. Retorque

blade carrier retaining nut to 400 ft. lbs.

READ AND UNDERSTAND THE ENTIRE OPERATING INSTRUCTIONS AND SAFETY SECTION OF THIS

MANUAL AND THE TRACTOR MANUAL BEFORE ATTEMPTING TO USE THE TRACTOR AND

IMPLEMENT. If you do not understand any of the instructions, contact your nearest authorized dealer for a

full explanation. Pay close attention to all safety signs and safety messages contained in this manual and

those affixed to the implement and tractor. OPS-U- 0001
