In order to reduce accidents and enhance the safe operation of mowers, Bush Hog, 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 Bush Hog 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 Bush Hog.

If you would like a VHS video tape of the video, please email AEMVideo@alamo-group.com or Fax

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.

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

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 or Implement without supervision. Make sure the

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

(SG-4)

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)

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)

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)

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)

BEFORE leaving the tractor seat, always set the parking 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

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)

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)

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)

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

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

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

the equipment. ^(SG-16)

SAFETY

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)

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 attempt to lubricate, adjust, or remove material from the Implement while it is in

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

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)

Always read carefully and comply fully with the manufacturer’s

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

chemical agent. ^(SG-22)

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)

PT5 09/10

Safety Section 1-6

SAFETY

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)

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)

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

300 feet (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 300 feet

of mower. ^(SGM-02)

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)

PT5 09/10

Safety Section 1-7

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

SAFETY

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

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

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

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

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

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 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)

PT5 09/10

Safety Section 1-8

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

SAFETY

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 POSSIBLY

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

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 300 Feet 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 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)

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

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)

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-07)

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

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

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

Relieve hydraulic pressure prior to doing any maintenance or repair work

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

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

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

starting any maintenance or repair work. ^(S3PT-09)

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)

SAFETY

This Implement may be 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)

In addition to the design and configuration of this Implement, including Safety Signs and Safety Equipment,

hazard control and accident prevention are dependent upon the awareness, concern, prudence, and proper

training of personnel involved in the operation, transport, maintenance, and storage of the machine. Refer

also to Safety Messages and operation instruction in each of the appropriate sections of the Tractor and

Equipment Manuals. Pay close attention to the Safety Signs affixed to the Tractor and Equipment. ^(SG-18)

INTRODUCTION

This PT5 Sickle Bar 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, and instruct. The Assembly Section instructs the owner/operator in

the correct assembly of the Implement using standard and optional equipment.

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

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

to appropriate maintenance. The Trouble Shooting Guide helps diagnose difficulties with implement 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 mower

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.

INTRODUCTION

The sickle bar boom is designed for medium-duty work. They can cut grass and weeds, around waterways,

under fences and other hard-to-reach areas.

For Non-Agricultural use, OSHA, ASABE, 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 Guards, 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.

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

automobile).

ASSEMBLY

TRACTOR SELECTION

The PT5 is specifically designed to be fitted to all tractors with Category I linkage facility and a minimum weight

inclusive of ballast to manufacturer’s specifications of 650 kg (1430 lbs.). The tractor should also be equipped

with an OPEN CENTER HYDRAULIC SYSTEM.

Check chains/stabilizer bars must be available to hold the machine firmly in position during transport and

operation. The tractor selected must have a relief valve setting between 2000 PSI (140 Bar) and 3000 PSI (210

Bar).

Ballast Weight

Irrespective of the size of the tractor it must be stable while operating the PT5 under all conditions. Due regard

must be paid to operating on slopes and front end ballast as well as rear wheel weights to counterbalance the

overhang of the cutterbar should be added as appropriate.

ATTACHMENT TO TRACTOR

1. Unbolt the upper halves of the yoke and fit them on either side of the tractor’s top hitch bracket with the 3/

4” UNF nut and bolt provided. If the tractor has only one top hitch position the bolt will replace the existing

top hitch pin. If more than one location is available, mount the yokes through an alternative position as it

will make it easier to put the machine on and take it off the tractor.

2. Do not tighten the nut at this stage.

3. Attach the machine to the three-point linkage and raise to give 200-250 MM (8”-10”) clearance under the

lowest part of the frame.

4. Rebolt the yoke halves together. It may be necessary to raise or lower the machine on the linkage to

achieve hole alignment. Adjust the top link until the main frame is vertical.

5. Tighten the nut and bolt securing the upper yoke just enough to eliminate any sideways movement. Do not

overtighten and squeeze the top hitch brackets.

6. Tighten the check chains/stabilizer bars.

7. Release its holding chain and position the control valve to suit the tractor and operator. This is achieved by

a combination of height adjustments in the mounting bar attachment and by bending the mounting bar

itself.

8. Turn the parking leg upside down and pin in position.

ASSEMBLY

COUPLING UP HYDRAULICS

Consult the tractor’s handbook for correct installation of the supply and return connection.

Note that if the tractor is equipped with one or more quick release hydraulic couplings the PT5 supply and

return hydraulic components may need to be rearranged to facilitate fitting to a variety of tractors.

The motor drain line must always be returned to a low pressure position i.e. Transmission plug.

Where no specific return connection is available and the transmission filter plug has to be used, an adaptor

must be fitted which then allows the motor return and the motor drain to utilize a common return location.

Run up the machine and operate through its complete range of movements including the operation of the

cutterbar drive. Check the tractor’s transmission oil level and top up if necessary.

You are now ready to proceed to the work site.

REMOVAL FROM THE TRACTOR

1. Select a firm level site.

2. Replace the stand leg to the park position with foot down.

3. Position the arms so that the motor is level with the bottom of the frame.

4. Raise tractor linkage to take the weight off the yoke. Where a common top link and yoke position is used,

the yoke must be unbolted in the middle. If different top link locations are used, the yoke may be unbolted

at the top.

5. Lower the machine to the ground and disconnect the three point linkage. Remove top halves of the yoke if

still attached to the tractor.

6. Use chain to tie the hydraulic control valve back to the main arm. This will make it easier for subsequent

coupling up.

7. Blank off hose ends or loop the hoses and join with coupling is available.

STORAGE

If the machine is to be left standing for an extended period of time, lightly coat the exposed portions of the ram

rods with grease. Subsequently, this grease which becomes contaminated with dust and grit should be wiped

off before the rams are next moved.

Liberally grease the cutterbar and replace the finger and knife guard. Remember to take caution and keep

fingers away from the knife.

If the machine is to be stored outside, lay a piece of tarpaulin or canvas over the control valve. Do not use a

plastic bag which could lead to rapid corrosion.
