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 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 mail [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.

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

and the potential hazards before operating the equipment.

The information and material listed above along with this Operator’s Manual can assist you in meeting the OSHA

requirement for annual operator training.

OSHA TRAINING REQUIREMENTS

The following training requirements have been taken from Title 29, Code of Federal Regulations Part

1928.57 (a) (6). www.osha.gov

Operator instructions. At the time of initial assignment and at least annually thereafter the employer shall instruct

every employee who operates an agricultural tractor and implements in the safe operating practices and servicing

of equipment with which they are or will be involved, and of any other practices dictated by the work environment.

To the Owner/Operator/Dealer

This Operator's Manual is an integral part of the safe operation of this machine and must be maintained with the

implement at all times. A Manual canister is provided on the implement where this manual can be properly stored.

If you lose or damage this manual a free replacement manual can be obtained from an authorized Bush Hog dealer

or by down loading the manual from the Bush Hog website www.bushhog.com

BEFORE YOU START! READ, UNDERSTAND, and FOLLOW the information provided in this manual, the AEM

Mower Safety manual and the tractor operator's manual carefully to learn how to operate and service your machine

properly. Failure to do so could result in personal injury to you and bystanders. All implements with moving parts

are potentially hazardous. Every effort has been made to ensure that the machine is safe but operators must avoid

engaging in unsafe practices and follow the written instructions provided. The manufacturer has designed this

implement to be used with all its safety equipment properly attached to minimize the chance of accidents.

SAFETY FIRST. Completely read and understand the safety section of this manual before operating this

equipment. Do not allow anyone to operate this equipment who has not fully read and understood this manual.

Contact your Dealer to explain any instructions that you do not fully understand.

The care you give your Bush Hog Implement will greatly determine your satisfaction with its performance and its

service life. Carefully read and follow the instructions in this manual to provide you with a thorough understanding

of your new implement and its intended use and service requirements.

All references made in this manual to right, left, front, rear, top or bottom are as viewed facing the direction of

forward travel with the implement properly attached to the tractor.

Replacement Parts information is located in a separate Parts Manual. Bush Hog mowers use balanced and

matched system components for blade carriers, blades, cuttershafts, knives, knife hangers, rollers, drivetrain

components, and bearings. These parts are made and tested to Bush Hog specifications. Non-genuine “will fit”

parts do not consistently meet these specifications. The use of “will fit” parts may reduce mower performance, void

warranties, and present a safety hazard. Use genuine Bush Hog mower parts for economy and safety.

For future reference, record your Bush Hog product model number and serial number.

INTRODUCTION

We are pleased to have you as a Bush Hog customer. Your Rotary Cutter has been carefully designed with

care and built with quality materials by skilled workers to give maximum service with minimum down time. This

manual is provided to give you the necessary operating and maintenance instructions for keeping your rotary

cutter in top operating condition. Careful use and timely service saves extensive repairs and costly downtime

losses. Please read this manual thoroughly. Understand what each control is for and how to use it.

Bush Hog typically offers three types of shielding to protect the operator, passerby, livestock, and property from

thrown objects... deflectors, single chain guards, and double chain guards. Shielding should be selected based

on the intended use of the mower. Double chain guards or deflectors should be used for highway, right-of-way,

parks or greenbelt mowing or all other mowing where human dwellings, vehicles, or livestock could be within

300 feet of the mower. Chain guards are more durable, provide a longer service life and require less

maintenance and replacement than deflectors. Single chain guards may be sufficient for agriculture and other

mower use only where passersby or property are not within 300 feet of the mower during operation.

No shielding is 100% effective in preventing thrown objects. The possibility of injury and property damage from

this hazard can be substantially reduce by selecting proper shielding, maintaining the mower and shielding in

good operational condition, inspecting the area for foreign debris before mowing, operating the mower at a

minimum cutting height of 4", and keep unprotected persons at a minimum distance of 300 feet from the

mower at all times during operation.

Safety is of primary importance to the owner/operator and to the manufacturer. Observe all safety precaution

decals on the machine and noted throughout the manual for safe operation of implement. If any assistance or

additional information is needed, contact your authorized Bush Hog dealer. The owner/operator/dealer should

know and understand the Safety Messages before assembly and be aware of the hazards of operating this

cutter 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.

KEY OPERATION POINTS

• Cutting performance and distribution are best when cutter is level from side to side and front to rear.

• In extra heavy material, rear chains will allow better discharge and better distribution than solid rear bands.

• Never operate the Mower below full PTO speed of 540.

• Corn should be cut at 5 to 6 mph. If full PTO rpm cannot be maintained, use one lower gear.

Operating Noise Level/Sound Pressure

The sound levels at the operator's ear from the attached machine (rotary cutter) are at least 10 dB(A) below the

levels from typical Agricultural tractors used to power and transport this machine. Therefore, the Noise

emission values given by the OEM of the Agricultural tractor used to power and transport this machine would

be valid when this machine is attached to and operated by that Agricultural tractor in all OEM recommended

applications.

SETUP INSTRUCTIONS - TAILWHEEL

Bush Hog SQ84T models as shipped from the factory Tailwheel Frame and Tailwheel mounted to the unit.

ADJUSTING FOR WORK

The cutter should be operated at the highest position which will give desired cutting results. This will help

prevent the blades from striking the ground, reducing blade wear and undue strain on the machine. For best

results under heavier cutting conditions, always tilt the cutter approximately 2 inches (51mm) lower in the

front.This tilt decreases horsepower requirements and increases potential ground speed. When fine shredding

is desired, adjust cutter deck level or slightly lower in the rear. This will keep the foliage under cutter until

thoroughly shredded. More power is required for shredding. Each cutter can be adjusted to several cutting

heights. The SQ84T can be adjusted from 2” to 12” of cutting height. To adjust, raise cutter and block securely

in position. Remove bolt from adjusting bracket shown in Figure below. Adjust tailwheel arm up or down and

secure in desired position.

2.5 Power Take Off (PTO)

This mower is designed to operate at a PTO speed of 540. Most tractors operate at either 540, or a

combination of 540 and 1000 RPM PTO speeds. The operating speed of the mower and tractor can be

determined by the number of splines on the driveline yoke and PTO output shaft. Those operating at 540

RPM will have a 6-spline shaft and those operating at 1000 RPM will have a 21-spline shaft. Note: The

mower will not operate on tractors equipped with a 1000 RPM 21-spline or 1000 RPM 20-spline, 1-3/4” shaft.

Refer to the tractor owner’s manual for instructions to change PTO speeds on models that operate at more

than one speed.

If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an

over-running clutch must be used between the PTO output shaft and the driveline of the mower. An

authorized tractor dealer can provide the over-running clutch and its installation if needed. OPS-R- 0066

The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing

conditions the SQ84T is 30 HP. Operating the mower with a tractor that does not

have adequate power may

damag

e the tractor engine. Exceeding recommended HP may cause mower damage by overpowering the unit

in heavy cutting conditions.

The tractor 3-point hitch must be rated to lift at least

720lbs (SQ84T). These models are designed to be

mounted on a tractor CAT I - 3 Point Hitch.

Refer to the tractor operator’s manual for the

category of the tractor being used. If the hitch does

not conform to ASABE CAT I dimensions, the

mower may not fit or raise properly. Consult an

authorized dealer for possible modification proce-

dures to mount non-conforming hitches.

Depending on the hitch category, certain size pins

are used to attach the mower to the tractor. CAT I

hitches require 7/8” lower and 3/4” upper diameter

hitch pins.

OPERATION

SQ84T 01/19 Operation Section 4-6

OPERATION

Do not connect the PTO driveline to the tractor or operate the implement unless the

implement is securely connected to the tractor.

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)

DANGER

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)

DANGER

2.6 Tire Spacing

Tractor tires should be set a minimum of 60”(1.5

mm) apart measured from inside of tire to inside of

tire. Refer to the tractor Operator’s Manual or

consult an authorized dealer for instructions to

change tractor tire spacing. OPS-R- 0062

3. GETTING ON AND OFF THE TRACTOR

Before getting onto the tractor, the operator must read and completely understand the implement and tractor

operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for

a complete explanation. OPS-U- 0007

Do not mount or dismount the Tractor while the tractor is moving. Mount

the Tractor only when th

e Tractor and all moving parts are

completelystopped.

3.1 Boarding the Tractor

Use both hands and equipped handrails and steps for support when boarding the tractor. Never use control

levers for support when mounting the tractor. Seat yourself in the operator’s seat and secure the seat belt

around you.

Never allow passengers to ride on the tractor or attached equipment. Riders can easily fall off and be

seriously injured or killed from falling off and being ran over. It is the operator’s responsibility to forbid all extra

riders at all times. OPS-U- 0008

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.

5. CONNECTING THE MOWER TO THE TRACTOR

Use extreme caution when connecting the mower to the tractor. The mower should be securely resting at

ground level or setting on blocks. Keep hands and feet from under the mower deck and clear of pinch points

between the tractor hitch arms and mower pins. OPS-R-0001

OPERATION

SQ84T 01/19 Operation Section 4-9

OPERATION

5.1 Connecting the Mower-Lift Type

1. Make sure the tractor is equipped with the

correct PTO shaft. Change shafts if needed.

2. Shorten or remove the tractor drawbar to avoid

interference when raising and lowering the

mower.

3. Board the tractor and start the engine. Position

the tractor to the mower with the 3-point lift

arms positioned at the same height and to the

outside of the mower hitch pins. Note: Set the

3-point lift control to “Position Control” so that

the lift arms maintain a constant height when

attaching the mower. See the tractor Operator’s

Manual for correct settings when attaching 3-

point equipment.

4. Turn off the tractor engine and dismount.

5. One lift arm at a time, align arm end hole

between the set of A-frame lift lugs. Insert hitch

pin through the lug and arm holes and insert

retaining pin into hitch pin.

6. Walk around to opposite side and repeat

procedure for remaining lift arm and hitch pin.

7. Extend or retract 3-point top link to align its end

hole with the holes of the mower’s top link.

Insert the top link hitch pin and insert retaining

pin into hitch pin.

8. Adjust any lower link check chains, guide

blocks, or sway blocks to prevent the mower

from swaying side to side and possible contact

with tractor rear tires.

OPERATION

6.1 Setting Mower Height- Lift Type - (Standard)

1. Park the tractor and mower on level ground.

2. Using the 3-point hitch control lever, position

the front of the mower with the side skids 1”

less off the ground than desired cut height. For

example, for a 3” cut, position the skids 2” from

the ground. Set the 3-point control lever stop at

this position to maintain this height when raising

and lowering the mower.

3. Shut down the tractor and remove the key.

4. Adjust the mower deck front to rear by

extending or retracting the 3-point top link.

Always set front of deck 3/4”

lower than rear for

best performance.

5. Level the mower side to side by manipulating

one lower lift arm length. On most tractors, at

least one of the lift arms is designed to allow for

manipulation of its length. Shortening or

extending will allow for deck leveling from side

to side.

6. Securely block up the mower at this height.

7. Remove the bolts securing the tailwheel beam

in position and allow the tailwheel to rest at

ground level. Align

tailwheel beam between

nearest sets of holes in beam support brackets

and reinstall support bolts on each side of

beam. Tighten all bolts and nuts.

6. SETTING THE MOWER

Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make

a more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow the contour of

uneven terrain. NOTE: Avoid very low cutting heights, striking the ground with the blades gives the most

damaging shock loads and will cause damage to the mower and drive. Blades contacting the ground may

cause objects to be thrown out from under the mower deck. Always avoid operating the mower at a height

which causes the blades to contact the ground. OPS-U- 0010

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)

DANGER

OPERATION

8. Extend the tractor’s top 3-point link so that

when lifting the mower, the front of the deck will

raise 2 to 2½” before the tail wheel leaves the

ground. This will allow the mower to follow the

contour of uneven terrain.

Note: Install optional check chains when there is a

problem with the hydraulic 3-Point lift maintaining a

set height or when a constant pre-adjusted cut

height is required. See Check Chains in the

Assembly Section for this accessory.

SQ84T 01/19 Operation Section 4-12

OPERATION

6.2 Setting Deck Pitch

Lower Horse Power - Better Fuel Efficiency

To increase fuel efficiency and lower horsepower

requirements for mower operation, the mower

should be operated with the deck approximately 3/

4" LOWER IN THE FRONT THAN THE REAR.

Operating the mower at this pitch will allow the

mower to cut the grass only once and requires less

work from the tractor.

Increase Mulching

To increase mulching of the grass or crop material

during mower operation, the mower should be

operated with the deck approximately 3/4" HIGHER

IN THE FRONT THAN THE REAR.

Operating the mower at this pitch will allow the

mower to cut the grass twice and can result in a

more even cut and improved distribution of the cut

material.

OPS-U-0041_B

7. DRIVELINE ATTACHMENT

The driveline yoke and tractor PTO shaft must be

dirt free and greased for attachment.

To connect the mower driveline to the tractor PTO

measure 3” back from universal joint shield and

mark on opposite section. Do this for both

sections.

4. Do this for both sections.

5. Raise and lower cutter to determine position

with greatest distance between PTO shaft and

gearbox input shaft. Shut down tractor leaving

cutter in position of greatest distance. Securely

block cutter in position.

6. Hold driveline sections parallel to each other

and check for minimum 6” overlap. If driveline

has been marked for cutting, overlap will be the

distance between two marks. if driveline has

less than minimum overlap, do not use. Contact

authorized Bush Hog dealer.

NOTE: If driveline is the correct length, omit the

following steps8-11andproceedtostep 12.

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

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

securely in the groove on the Tractor PTO shaft. Push and pull the driveline back and forth

several times to ensure it is securely attached. A driveline not attached correctly to the

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

Implement.

9. DRIVING THE TRACTOR AND IMPLEMENT

Safe tractor transport requires the operator possess a thorough knowledge of the model being operated and

precautions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the

weight of the implement and the tractor operating controls are set for safe transport. To ensure safety while

driving the tractor with an attached implement, review the following. OPS-U- 0012

Never run the Tracto

r engine in a closed building or without adequate ventilation. The

exhaust fumes can be hazardous to your health.

(SG-23)

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.

9.1 Starting the Tractor

The procedure to start the tractor is model specific.

Refer to the tractor operator’s manual for starting

procedures for your particular tractor. Consult an

authorized dealer if the starting procedure is

unclear. Ensure the 3-point control lever is in the

lowered position and the PTO is disengaged before

starting the tractor. OPS-U-0033

9.2 Brake and Differential Lock Setting

Make sure the tractor brakes are in good operating

condition. Tractor brakes can be set to operate

independently allowing single rear wheel braking

action or locked together to provide simultaneous

rear wheel braking. FOR MOST DRIVING AND

OPERATING CONDITIONS, THE BRAKE PEDALS

SHOULD BE LOCKED TOGETHER TO PROVIDE

THE MOST EFFECTIVE BRAKING ACTION.

Always disengage the tractor differential lock when

turning. When engaged the differential lock will

prevent or limit the tractor from turning. During

normal cutting conditions, locking the differential

provides no benefit and should not be used. OPS-

U- 0013

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

When operating down a hill or on wet or rain slick roads, the braking distance increases; use

extreme care and reduce your speed in these conditions. When operating in traffic, always

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

you and watch out for the other guy.

9.3 Raising the Mower

Using the tractor 3-point hitch control lever, raise

the mower off the ground about 6”, or just high

enough to clear any ground obstacles. When

raising the mower, make sure all connection points

are securely attached and at least 1” clearance is

maintained between the driveline and the deck. If

necessary, place an upper lift stop on the 3-point

hitch control lever to limit the height the mower can

be raised to avoid driveline damage

. OPS-R-0042

9.4 Driving the Tractor and Mower

Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the

tractor and mower. Moving slowly at first will also prevent the tractor from rearing up and loss of steering

control. The tractor should never be operated at speeds that cannot be safely handled or which will prevent

the operator from stopping quickly during an emergency. If the power steering or engine ceases operating,

stop the tractor immediately as the tractor will be difficult to control.

Perform turns with the tractor and mower at slow

speeds to determine how the tractor with an

attached mower handles a turn. Determine the

safe speed to maintain proper control of the tractor

when making turns. When turning with a towed

implement, the overall working length of the unit is

increased. Allow additional clearance for the

mower when turning.

To avoid overturns, drive the tractor with care and

at safe speeds, especially when operating over

rough ground, crossing ditches or slopes, and

turning corners. Tractor wheel tread spacing

should be increased when working on inclines or

rough ground to reduce the possibility of tipping.

Use extreme caution when operating on steep

slopes. Keep the tractor in a low gear when going

downhill. DO NOT coast or free-wheel downhill.

OPS-R-0019

OPERATION

SQ84T 01/19 Operation Section 4-28

OPERATION

9.5 Crossing Ditches and Steep Inclines

When crossing ditches with steep banks or going up

sharp inclines, it is possible that the main driveline

inner profile will penetrate into the outer housing to its

maximum depth until the assembly becomes solid

(driveline is at its extreme shortest length). This type

of abusive operation can cause serious damage to

the tractor and mower drive by pushing the PTO into

the tractor and through the support bearings or

downward onto the PTO shaft, breaking it off.

Damage resulting from over-collapse of the driveline’s inner profile and its outer housing

may allow the driveline to come loose from the Tractor which could cause bodily injury to the

operator or bystanders and/or extensive damage to the Tractor or Implement. OPS-R-0020

When confronted with an incline or ditch, do not

approach from an angle which is perpendicular or

straight on as damaged to over collapse of the

driveline may occur.

When crossing such terrain, the implement should

be fully lowered for a lower center of gravity and

added stability. OPS-R-0021

OPERATION

SQ84T 01/19 Operation Section 4-29

OPERATION

Inclines and ditches should be approached along a

line which is at an angle as shown. This type of

path will reduce the possibility of over-collapse of

the driveline and resulting damage. If the gradient

is so steep that such an approach increases the

possibility of a tractor roll-over, select an alternate

crossing path.

When operating the tractor and mower across

slopes and inclines, through ditches, and other

uneven terrain conditions, it is important to maintain

sufficient deck to ground clearance. Blade contact

with the ground may cause soil, rocks and other

debris to be thrown out from under the mower

resulting in possible injury and/or property damage.

Ground contact also produces a severe shock load

on the mower drive and to the mower blades

resulting in possible damage and premature wear.

OPS-R-0022

10. OPERATING THE TRACTOR AND IMPLEMENT

THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND

IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE. The operator must read and

understand the Safety and Operation Sections of the implement and tractor operator’s manuals. These

manuals must be read and explained to any operator who cannot read. Never allow someone to operate the

implement and tractor without complete operating instructions.

Before starting any operation, the operator must become familiar with the area to be worked in and any

obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special

attention should be paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area.

OPS-U- 0015

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)

OPERATION

SQ84T 01/19 Operation Section 4-30

OPERATION

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

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

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

in serious injury or even death. Inspect the cutting area for such objects before mowing.

Remove any like object from the site. Never allow the cutting blades to contact such items.

(SGM-06)

10.1 Foreign Debris Hazards

Before mowing, inspect the area to make sure

there are no foreign objects that the mower blades

could hit or become entangled with. Remove all

foreign objects and debris. If objects are too big to

remove, mark them clearly and be sure to prevent

the mower blades from contacting them.

If you hit a solid object or foreign debris, stop the

mower and tractor at once. Immediately idle the

engine speed and disengage the PTO. Wait for all

mower rotating motion to stop, then raise the

mower and move the tractor and implement off the

object. Inspect the area and remove, or mark the

location of the debris. Inspect the condition of the

mower and make any needed repairs immediately.

Make sure the blades are not damaged and the

carrier is balanced before resuming operation.

Always wear your seat belt securely fastened and

only operate the tractor and mower with the ROPS

in the raised position. If the tractor or mower hits a

tree stump, rock, or bump, a sudden movement

could throw you off of the seat and under the

tractor and/or mower. The seat belt is your best

protection from falling off the tractor and the ROPS

provides protection from being crushed during a

tractor roll-over. OPS-R-0023

Remove Foreign Material

Raise Mower over solid objects

10.2 Bystanders/Passersby Precautions

If a bystander comes within 300 feet of the tractor while the mower is being operated, stop the tractor at once,

idle the engine and disengage the PTO. Do not engage the PTO again until all bystanders are well past the

300 foot distance. OPS-R-0024

OPERATION

SQ84T 01/19 Operation Section 4-31

OPERATION

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)

10.3 Engaging the Power Take Off (PTO)

Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement

must be completely lowered and the deck positioned at a safe operating height. NEVER engage the PTO with

the implement in the raised position.

Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to

the on position, and slowly increase the engine speed until the PTO is operating at the rated speed. If you

hear unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the

implement to determine the cause of the noise or vibration and repair the abnormality. OPS-U- 0027

Do not let the Blades turn whe

n the Mower Deck is raised for any

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

exposes the Cutting Blades which creates a potentially serious hazard

and could cause serious injury or even death from objects thrown from

the Blades.

(SRM-07)

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

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

and the decks are securely blocked up.

(SGM-09)

DANGER

OPERATION

SQ84T 01/19 Operation Section 4-32

OPERATION

10.5 Operating the Mower

Only operate the mower from the tractor operator’s seat with the seatbelt securely fastened. The tractor must

be equipped with a ROPS in the raised position or a ROPS cab.

The mower is designed to cut vegetation up to 2” in diameter. Sharp blades will produce a cleaner cut and

require less power. Travel at a speed that allows the mower sufficient time to cut through the vegetation and

maintain the PTO operating speed to prevent overloading the mower and tractor. Choose a driving pattern that

provides the maximum pass length and minimizes turning.

Under certain conditions, tractor tires may roll some grasses down preventing them from being cut at the same

height as the surrounding area. When this occurs, reduce the tractor ground speed while maintaining the

operating speed of the mower. A slower ground speed will permit grasses to at least partially rebound and be

cut. Taking a partial cut and/or reversing the direction of travel may also help produce a cleaner cut.

Avoid mowing in the reverse direction when possible. In situations where the mower must be backed to

access areas to be cut, make sure there are no persons or other foreign debris behind the mower before

mowing in reverse. When mowing in reverse, operate the tractor and mower at a reduced ground speed to

ensure tractor and mower control is maintained.

10.4 PTO RPM and Ground Speed

Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut.

Recommended speed for efficient mower performance is between 2 and 5 mph(3-8 kph). Operate the mower

at its full rated PTO speed to maintain blade speed for a clean cut. Refer to the tractor operator’s manual or

the tractor instrument panel for the engine speed and gear to provide the required PTO and desired ground

speed. Make sure that the mower is operating at its full rated speed before entering the vegetation to be cut.

If it becomes necessary to temporarily regulate engine speed, increase or decrease the throttle gradually.

Ground speed is achieved by transmission gear selection and not by the engine operating speed. The

operator may be required to experiment with several gear range combinations to determine the best gear and

range which provides the most ideal performance from the mower and most efficient tractor operation. As the

severity of cutting conditions increase, the ground speed should be decreased by selecting a lower gear to

maintain the proper operating PTO speed. OPS-R-0025

Do not exceed the

rated PTO speed for the Implement. Excessive PTO speeds can cause

Implement driveline or blade failures resulting in serious injury or death.

(SG-26)

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

correct mowing speed depends on terrain condition and grass type, density, and height of

cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds

when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power

lines, or when debris and foreign objects are to be avoided.

(SGM-07)

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

closed.

(SGM-11)

OPERATION

SQ84T 01/19 Operation Section 4-33

OPERATION

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

lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least

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)

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

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

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

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

(SGM-08)

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

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

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

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

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

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

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

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

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

the mower deck.

(SGM-12)

When you get to the end of a pass, slightly raise the

mower (2-4”) before turning. Never raise the

mower entirely while the blades are turning. If the

mower must be raised higher than 12” from ground

level, disengage the tractor PTO and wait for all

mower rotation to come to a complete stop before

proceeding to raise the mower.

When turning, the angle between the tractor and

mower should not be so great that a clattering of

the U-joints occurs. Sharp turns can cause

premature failure of the joints and place pressure

on the tractor PTO shaft and could cause extensive

mechanical damage to the mower and tractor.

OPS-R-0027_A

OPERATION

SQ84T 01/19 Operation Section 4-34

12. MOWER STORAGE

Properly preparing and storing the mower at the end of the season is critical to maintaining its appearance

and to help ensure years of dependable service. The following are suggested storage procedures:

• Thoroughly clean all debris off the mower to

prevent damage from rotting grass and

standing water.

• Lubricate all mower grease points and fill

gearbox oil levels as detailed in the

maintenance section.

• Tighten all bolts and pins to the recommended

torque.

• Check the mower for worn and damaged

parts. Perform repairs and make

replacements immediately so that the mower

will be ready for use at the start of the next

season.

• Store the mower in a clean, dry place with the

mower housing resting securely on blocks or

at ground level.

• Keep the driveline yoke from sitting in water, dirt and other contaminants.

• Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the mower.

It is critical that driveline clutches slip when an obstacle or heavy load is encountered to avoid mower and/or

tractor damage. If the mower sits outside for an extended period of time or is exposed to rain and/or humid

air, the clutch lining plates must be inspected to ensure they are not frozen together from rust or corrosion. If

the mower has been exposed to such conditions, at the start of each mowing season, and any time it is

suspected that the slip clutch plates may be frozen together, readjust the slip clutch as detailed in Seasonal

Clutch Maintenance of the maintenance section in this manual. OPS-R-0032_A

Never allow children or other persons to ride on the Tractor or Implement.

Falling off can result in serious injury or death.

the driveline to the mower deck to prevent driveline

damage or loss during transport. OPS-R-0034

13.1 Transporting on Public Roadways

Extreme caution should be used when transporting the tractor and implement on public roadways. The tractor

must be equipped with all required safety warning features including a SMV emblem and flashing warning

lights to alert drivers of the tractor’s presence. Remember that roadways are primarily designed for

automotive drivers and most drivers will not be looking out for you, therefore, you must look out for them.

Check your side view mirrors frequently and remember that vehicles will approach quickly because of the

tractor’s slower speed. Be extremely cautious when the piece of equipment that you are towing is wider than

the tractor tire width and/or extends beyond your lane of the road.

Make sure that a proper size safety tow chain is secured between the tractor and implement before entering a

public road. OPS-U- 0019

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.

13.2 Hauling the Tractor and Implement

Before transporting a loaded tractor and implement, measure the height and width dimensions and gross

weight of the complete loaded unit. Ensure that the load will be in compliance with the legal limits set for the

areas that will be traveled through

Use adequately sized and rated trailers and equipment to transport the tractor and implement. Consult an

authorized dealer to determine the proper equipment required. Using adequately sized chains, heavy duty

straps, cables and/or binders, securely tie down both the front and rear of the tractor utilizing the proper tie

down locations as specified by the tractor manufacturer.

Arrange the chains so that when tightened, the chains are pulling downward and against themselves.

Carefully tighten the securing chains or other fasteners using boomers or binders to apply maximum tension.

Use extreme care when attaching and removing the securing devices as the extreme tension involved when

released has the potential to inflict serious injury.

While hauling the tractor and implement, make occasional stops to check that the tractor and implement have

not moved or shifted and that the securing chains have maintained tension. If during transport a hard braking,

sharp turning, or swerving action was performed, stop at the next safe location to inspect the security of the

the proper level.

To check the oil level in both the gearboxes

remove the check plug on the side of the gearbox.

The oil should be level with the Check Plug hole.

If the oil is not at this level, remove the Vent Plug

and add EP80W-90 gear oil until it comes out the

check plug hole (Do Not fill past this point).

Replace the Check Plug and the Vent Plug.

If adding oil to a dry gearbox allow time for the oil

to fill the lower portion of the gearbox and check to

see if additional oil is required to bring oil up to the

proper level.

Do not overfill the gearbox!

NOTE: Overfilling of Gearbox will cause pressure

to build up and cause Grease Seals to leak.

BLADE SERVICING

Inspect blades before each use to determine that they are properly installed and in good condition. Replace

any blade that is bent, excessively nicked, worn, or has any other damage. Small nicks can be ground out

when sharpening.

Use only original equipment blades on this cutter. They are made of special heat-treated

alloy steel. Substitute blades may not meet specifications and may fail in a hazardous

manner that could cause injury.

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

WELD ON BLADES SINCE THIS WILL LIKELY CRACK OR OTHERWISE DAMAGE THE

BLADE WITH SUBSEQUENT FAILURE AND POSSIBLE SERIOUS INJURY FROM

THROWN BLADES.

(SGM-10)

• Manually wiggle the blade carriers to check for any looseness.

• Retighten any loose parts.

• Recheck torque every 50 hours.

Operating with loose blade hardware will damage the blade holder and blades. Whenever

the blades have been removed or replaced, the hardware must be retightened after the first

eight hours of operation. On new units check blade hardware and the blade nut torque after

first 8 hours.

Operating with loose blade holder will damage the blade holder and output shaft, two initial

tightenings are required. Retighten after one hour and again after the day of operation. In

severe cutting conditions or commercial use, a daily inspection is required.

To help prevent structural damage caused by loose hardware, tighten gear case hardware

as specified. Check torque after first 8 hours of use and every 50 hours thereafter.

NOTE: Correct Blade Rotation is counter-clockwise viewed from the top.

Inspect Blades daily for normal wear. If Blades have a notch worn into the leading worn into

the leading edge at the lower bend more than 1/2” DEEP (due to running in gravel and/or

the ground), REPLACE BOTH BLADES ON THAT CARRIER IMMEDIATELY. Failure to

replace such abnormally worn blades may lead to catastrophic failure of the blade and

ejection of the broken part with tremendous force which may cause bodily injury or death.

NOTE: Replace Blades in pairs after no more than 1/2” notch wear.

BLADE REMOVAL

Remove lockwasher and nut from blade bolt through inspection hole in deck of mower near the gearbox to

remove blades for sharpening or replacement. See Figure below. Always replace lockwasher and nut

when replacing blade bolt. When installing blades be sure and check blade bolt pivot diameter for wear.

Replace bolt if worn more than 1/4 inch at any point. Tighten nut to 600 ft. lbs.

BLADE SHARPENING

When sharpening blades, grind each blade the same amount to maintain balance. Follow

original sharpening pattern as shown in Figure Mnt-R-0008. Always sharpen blades by

grinding. Always sharpen both blades at same time to maintain balance. The difference in

blade weights should not exceed 1 ounce. Unbalanced blades will cause excessive

vibration which can damage gear box bearings. Vibration may also cause structural cracks

in cutter housing. DO NOT heat and pound out edge. Do not sharpen blade to a razor edge,

but leave a 1/16” blunt edge. Do not sharpen back side of blade.

Avoid personal injury. Always block the cutter up to prevent if from falling when the blades

and/ or carrier are being serviced.

MAINTENANCE

SQ84T 01/19 Maintenance Section 5-8

MAINTENANCE

BLADE CARRIER INSTALLATION

BLADE CARRIER REMOVAL

Remove cotter pin and loosen slotted nut on gearbox shaft. Loosen but do not remove the nut until the blade

carrier is loosened. Use a suitable 2 jaw gear puller to pull carrier off tapered gearbox shaft. If gear puller is not

available use long bar inserted through blade bolt access hole with end against rotor bar. Strike opposite end of

bar with sledge hammer. Rotate blade carrier 180 degrees and repeat process until carrier breaks loose.

The SQ84T is a Dual Spindle machine with two blade carriers which have overlapping blade travel circles. The

carriers MUST be timed to avoid the blades from striking each other during operation.

When replacing the blade carriers follow the illustration below for proper placement.

Clean the splines on both the blade carrier and output shaft. Position carrier on the gearbox output shaft and

install special washer nut.

Tighten nut holding blade carrier to minimum 450 ft. pounds, strike the carrier near the hub several times with a

heavy hammer to seat the hub. Use a suitable spacer over the nut to prevent damage to the nut and threads.

Retighten the nut to 450 ft. pounds. Install cotter pin and spread.

Operating the m

owe

r with a loose blade pan or holder can damage the taper connection on

the gearbox output shaft. To ensure proper seating between the blade holder and output

shaft, check and tighten the retaining nut after the first day of operation. Recheck the blade

carrier attachment each morning before operating. Grasp the carrier firmly with both hands

and try to push and pull the carrier with one hand while pulling and pushing with the other

hand to try to rock or oscillate th

e blade carrier. I

f the carrier is loose, retighten the retaining

nut before operating the mower.

Always recheck gearbox output shaft slotted blade carrier retaining nut torque after a few

hours operation.

Avoid personal injury. Do not work under cutter without support blocks to keep frame from

falling.

SLIP CLUTCH OPERATIONAL CHECK

NOTE: After implement has been stored for 30 days or more, perform the following operational check:

1. Loosen eight nuts retaining clutch springs 1/3 turn or until spring can be turned with fingers.

2. With tractor at idle speed, engage tractor PTO drive for 2-3 seconds. Clutch should lip without turning

blades. If clutch does not slip, contact your authorized Bush Hog dealer.

3. Retighten nuts to within 1/64” of original position. Initial spring length is shown in Figure Below.

Overtightening spring nuts may cause damage to implement and/or tractor due to incorrect

slip clutch torque setting. Always follow the proper adjustment procedure.

SLIP CLUTCH ADJUSTMENT

Do not overtighten nut and cause spring to become solid as this will cause shaft to fail.

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)

1.26”

(32mm)

The slip clutch is factory present to the correct torque for protecting implement and tractor. Periodic adjustment

is recommended. Should adjustment be needed, first check to be sure all spring lengths are the same. Initial

spring length is shown in Figure Above. If necessary, adjust nut on any spring that is unequal. Adjust all eight

spring retaining nuts 1/3 of a turn (2 flats on a nut) and check clutch slippage. If further adjustment is neces-

sary, do so in 1/3 turn increments. Adjust only to provide sufficient torque to prevent slippage under normal

conditions. Occasional slippage is normal for driveline protection. If satisfactory results cannot be obtained,

consult you Bush Hog dealer.
