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 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 AEMVid[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.

good repair.

• DRIVELINES: I have made certain that all driveline, gearbox, and other shields are in good repair and fas-

tened securely in place to prevent injuries from entanglement or thrown objects.

• HYDRAULIC MACHINES: I have explained the necessity of using clean hydraulic oil, changing filters as

instructed, stopping leaks, damage caused by operating with over-heated oil, caring for hoses, using hoses of

proper rating, maintaining the specified operating pressure and the potential hazard of oil’s penetrating the

skin.

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 two types of shielding to protect the operator, passerby, livestock, and property from

thrown objects... 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 6", 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 precautions

decaled 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

NOTE: All references made in this manual to right, left, front, rear, top or bottom are as

viewed facing the direction of forward travel with implement properly attached to tractor.

The Model 2820/12820 Rotary Cutter consists of a center unit with two variable position

wings together having a cutting width of 20 feet (6.1m). Wing operating angles and

machine cutting height are independently controlled using hydraulic cylinders. A self-

leveling linkage maintains a level cutter at all cutting heights.

Power from the tractor PTO is split at the power divider gearbox and supplied to each of

the blade gearboxes. Each blade gearbox has two free-swinging uplift blades designed

to cut grass, corn stalks and light brush. Free-swinging blades reduce the shock of

impact when a stationary object is hit. Slip clutches are installed on each gearbox for

additional protection. Front and rear discharge shields are included as standard

equipment.

ASSEMBLY

DEALER SET-UP INSTRUCTIONS

The mower as received from the factory is virtually completely assembled and requires minimum time to

complete assembly and is ready for sale.

ASSEMBLY

Select a suitable work area large enough to allow for lowering of the wings. Use extreme caution when

connecting the mower to the tractor. The mower should be securely resting at ground level or sitting on blocks.

Keep hands and feet from under the mower deck and clear of pinch points between the tractor and mower.

The unit comes with all axles and axle arms attached and tires on the center unit. Wing tires will need to be

attached to the wing axle arms and if the unit has dual wheel center axle arms, two tires will be assembled to

these axle arms.

On a fully assembled unit, do not release the Wing Lock Pin until the hoses are attached to

the tractor and the Wing Cylinders are filled with oil. Always keep bystanders away while

raising and lowering the wings.

To lower the wings, hook the hydraulic hoses to the tractor. From the Operators

Seat use the tractor hydraulic control levers to fill wing cylinders with oil (Refer to

Operation Section). Keep coworkers and bystanders away from the implement

while filling. For implements with the wings in the raised or transport position,

filling the cylinders should raise the wings slightly and loosen the wing lock pin.

DO NOT release the wing lock pin if there is a force on the lock. Use tractor

hydraulic control levers to lower the wing(s). Continue to hold the control lever

until both wings are down and the wing cylinders are fully retracted or extended.

Continue to cycle the cylinders several times by raising and lowering the wings

fully to remove any trapped air. If there is sponginess during the raising cycle, this

may indicate that air is entrapped in the hydraulic circuit. Continue to cycle the

cylinders until all sponginess is removed.

The implement wings should lower slowly when they are allowed to float down

and are not powered down. This is a safety feature built into the system. If the

wings fall rapidly, have the cylinders repaired before operating the implement.

2.1 ROPS and Seat Belt

The tractor must be equipped with a Factory Cab and seat belt to protect the operator from falling from the

tractor and being crushed or run over by the tractor and/or implement resulting in serious injury or death. Only

operate the tractor while seated in the operator’s seat with the seatbelt securely fastened around the operator

OPS-U- 0051

2.2 Tractor Safety Devices

If transporting or operating the tractor and implement near a public roadway, the tractor must be equipped with

proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of

the unit. Lights and a SMV emblem must be equipped directly on implements if the visibility of the tractor

warning signals are obscured.

Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were

removed for access to connect, service, or repair the tractor or implement. Never operate the tractor PTO

with the PTO master shield missing or in the raised position. OPS-U- 0004

OPERATION

2820-12820 01/15 Operation Section 4-5

OPERATION

3. Tractor Horsepower

The horsepower required to operate the mower depends on several operating factors including the vegetation

to be cut, terrain condition, operator experience, condition of the mower and tractor, and others. For most

mowing conditions, the 2820/12820 mower requires a tractor with a minimum of 90 HP. Operating the mower

with a tractor that does not have adequate power may damage the tractor engine. Exceeding 120 HP may

cause mower damage by overpowering the unit in heavy cutting conditions.

3.1 Drawbar

Constant Velocity and Standard Driveline.

Position the length of the drawbar from the end of

the tractor PTO shaft to the drawbar hitch hole

according to the operating speed of the mower. If

the mower is a 540 RPM unit, position the drawbar

length from shaft end to hitch hole at 14”. For 1000

RPM mowers, set the drawbar length at 16” for 21

spline 1-3/8” mowers and at 20” for 1-3/4” 20 spline

mowers. Do not use PTO adaptors. Use of PTO

adaptors will invalidate your warranty.

3.2 Tractor Hydraulics

The mower center section and each wing are positioned with hydraulic cylinders that are operated by the

tractor hydraulic pump. The tractor must have a minimum of 2 hydraulic control valves devoted to the mower

unless the tractor is fitted with a 3-spool control valve (extra equipment).

A 3-spool control valve is required if the tractor is equipped with a single valve and is recommended for those

with two valves so that the center section and each wing can be controlled independent of one another. Refer

to the Assembly Section of this manual for properly equipping the tractor with a 3-spool control valve. Tractors

equipped with three hydraulic ports can position the center section and each wing independently with no extra

equipment. If the tractor is equipped with only two hydraulic ports and a 3-spool control valve is not used, the

wings cannot be operated independently and will raise and lower at different speeds.

3.3 Front End Weight

A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end

weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the

front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front

weights and weight carriers can be purchased through an authorized tractor dealership. OPS-U- 0005

OPERATION

2820-12820 01/15 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.

3.4 Power Take Off (PTO)

Depending on the unit, the mower is designed to operate at a PTO speed of 540 or 1000 RPM. 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 20 or 21-

spline shaft. Note: 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-U- 0006_A

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)

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)

3.5 Tire Spacing

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

m) 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

OPERATION

2820-12820 01/15 Operation Section 4-7

OPERATION

4. 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 the Tractor and all moving parts are completely

stopped.

(SG-12)

4.1 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.

(SG-11)

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

Falling off can result in serious injury or death.

(SG-10)

4.2 Dismounting the Tractor

Before dismounting, park the tractor and implement on a reasonably level surface, apply the parking brake,

idle the engine down, disengage the PTO, and lower the implement to the ground. Shut down the tractor

engine according to the operator’s manual, remove the key, and wait for all motion to completely stop. Never

leave the seat until the tractor, its engine and all moving parts have come to a complete stop.

Use hand rails and steps when exiting the tractor. Be careful of your step and use extra caution when mud,

ice, snow or other matter has accumulated on the steps or hand rails. Use all handrails and steps for support

and never rush or jump off the tractor. OPS-U- 0009

OPERATION

2820-12820 01/15 Operation Section 4-8

OPERATION

BEFORE leaving the tractor seat lower the implement, 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)

5. STARTING THE TRACTOR

The operator must have a complete understanding of the placement, function, and operational use of all

tractor controls before starting the tractor. Review the tractor operator’s manual and consult an authorized

dealer for tractor operation instructions if needed.

Essential Tractor Controls:

• Locate the light control switch.

• Locate the engine shut off control.

• Locate the brake pedals and the clutch.

• Locate the PTO control.

• Locate the 3-point hitch control lever.

• Locate the hydraulic remote control levers.

Before starting the tractor ensure the following:

• Conduct all pre-start operation inspection and service according to the tractor operator’s manual.

• Make sure all guards, shields, and other safety devices are securely in place.

• The parking brake is on.

• The PTO control lever is disengaged.

• The 3-point hitch control lever is in the lowered position.

• The hydraulic remote control levers are in the neutral position.

• The tractor transmission levers are in park or neutral.

Refer to the tractor owner’s manual for tractor starting procedures. Only start the tractor while seated and

belted in the tractor operator’s seat. Never bypass the ignition switch by short circuiting the starter solenoid.

After the tractor engine is running, avoid accidental contact with the tractor transmission to prevent sudden

and unexpected tractor movement. OPS-U-0028

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

exhaust fumes can be hazardous to your health.

(SG-23)

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.

6.1 Connecting Mower Tongue to the Tractor

1. Ensure the tractor is equipped with the correct

PTO shaft and the drawbar is set at the correct

length.

2. Using the parking jack, position the tongue

clevis to the height of the tractor drawbar.

Adjust the mower tongue to be level and

parallel with the tractor drawbar using the

control rod connecting the mower tongue to the

deck.

3. Board the tractor and start the engine. Back the

tractor to the mower aligning the drawbar hitch

hole with the mower tongue clevis. Turn off the

tractor engine, place the tractor in park, and set

the parking brake before dismounting.

4. To attach the mower, place two 1” flatwashers

(1) positioned under top lip of tongue clevis and

to the top of drawbar. Insert a 1” diameter

grade 5 or 8 bolt (3) through clevis and drawbar

and retain in position with a 1” locknut (4).

Tighten the locknut securely but do not

overtighten which could spring or break the

clevis. NEVER attach mower to the tractor with

a pin not having a nut.

5. Securely attach the mower safety chain to the

tractor drawbar or drawbar support frame.

6. Lower the jack until the tongue is completely

supported by the drawbar. Remove jack from

the tongue and place on storage bracket of

mower.

6. 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

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

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

and Tractor hitches.

(S3PT-15)

OPERATION

2820-12820 01/15 Operation Section 4-10

OPERATION

Safety Tow Chain

If the mower is towed on a public roadway, a safety chain with tensile strength equal to or greater than the

gross weight of the mower must be connected between the tractor and mower. This will help control the

implement in the event the tongue becomes disconnected from the drawbar. Make sure the chain is attached

to a secure location on the tractor and not to an intermediate support. After connecting both ends of the safety

chain, drive the tractor to the right and left to check for proper chain length. Adjust length as necessary and

allow only enough slack in the chain to make a maximum turn in both directions. Use chain intermediate

support on tractor drawbar to minimize chain slack. When not in use, store the safety chain to protect it from

mud or standing water by wrapping the chain around the tongue. Replace the safety chain if one or more links

or end fittings are broken, stretched or otherwise damaged or deformed.

6.2 Connecting Mower Hydraulic Lines to the Tractor

With the tractor shut down and secured in position, relieve hydraulic pressure from the tractor by moving the

control levers back and forth several times or placing the levers in the float position.

When connecting the mower hydraulic lines, keep hoses, quick couplers, and swivels free of contamination.

Never leave a disconnected hose end open and cap the tractor hydraulic outlet ports when not in use. If the

tractor ports or mower hydraulic hose ends become contaminated, wipe clean with a rag before connecting.

Operating Mower Hydraulics with Three Tractor Hydraulic Ports

Connect one hose into each hydraulic port. Connect lines to correspond with position of hydraulic control

levers.

Operating Mower Hydraulics with Two Tractor Hydraulic Ports

The lines that operate the wings must be plumbed together and will be controlled using one hydraulic control

valve and the center section with the remaining control valve. Ensure that the operator is aware that each wing

cannot be controlled independently nor will they raise and lower simultaneously.

Operating the Mower Hydraulics with a 3-Spool Hydraulic Control Valve (Extra Equipment)

Ensure the valve matches the hydraulic operating system of the tractor (open or closed center). Refer to the

Assembly Section for additional information on equipping the tractor with a 3-spool control valve.

Mount the valve bank to a tractor fender or other accessible location. Connect valve bank inlet and outlet lines

to outlets of the same tractor hydraulic port. Connect the mower hydraulics to the control valve bank with the

center section line to the right port. Connect the wing cylinder lines to the control valve positioned to

correspond with the left and right wing.

To activate the 3-spool hydraulic control valve, tie the tractor’s hydraulic control lever back to keep hydraulic oil

continuously fed to the valve bank.

Hydraulic Line Support

After connecting the mower hydraulic lines to the tractor, support the hoses with the equipped brackets. Ensure

that hoses do not contact the driveline, do not bind while turning, and do not become pinched or kinked.

Hydraulic Cylinder Priming

Hydraulic Cylinders must be filled with hydraulic oil before removing the wing transport lock pins to lower the

mower wings. Hydraulic cylinders and lines are filled by holding the valve control levers in the raised position

until the cylinders fully retract (wing cylinders) and extend (center cylinder). Place control levers in the float

position and repeat process a second time. Ensure wings are entirely supported by the cylinders before

removing the transport lock pins. NEVER drive out bar pins and NEVER remove bars that have tension on

them.

7. 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.

7.1 Setting Deck Height

LEVELING DECK CENTER SECTION

1. Place the tractor and mower on a level surface

and lower both wings.

2. Using the center section hydraulic cylinder,

raise to transport height and loosen level rod

jam nuts. Position the mower so the skid shoes

are 1” less off the ground than the final cut

height. For example, for a 3” cut raise or lower

the mower until the skid shoes are

approximately 2” off the ground.

3. Shut down the tractor, place the transmission in

park, and set the parking brake before

dismounting.

4. Level the mower deck front to rear by adjusting the leveling rods linking the tongue to the rear axle. DO

NOT allow feet or other body parts underneath the mower when making adjustments. To adjust rod length

turn the turnbuckles. To lower the front, lengthen the rods and to raise the front, shorten the rods DO NOT

unscrew turnbuckles to the point that either rod threaded ends becomes disconnected which will cause the

mower to fall. Raise to transport height and re-tighten jamnuts when deck is leveled.

5. IMPORTANT: Alternate adjustments between rods and adjust at equal lengths to maintain equal tension.

Improper adjustments may cause rods to snap or bend.

6. Place split collar assemblies on the center axle hydraulic cylinder rod to maintain a set cutting height each

time the mower is raised and lowered.

LEVELING WING SECTIONS WITH CENTER

Wings should be adjusted before use if they are not level with center deck section. Lower cutter until skids on

center section are approximately 1-2 inches off ground. Remove wing transport lock pin(s) and place in pin

storage hole. Lower wing(s) to ground allowing weight to rest on wheel(s). If wing(s) are not level (parallel) to

center section, loosen jam nut and turn turnbuckle body to adjust. Adjust longer to raise the wing outside edge

and shorter to lower the wing outside edge. It may be necessary to use wing lift cylinder to relieve pressure

from the linkage retaining pin. Tighten jam nut.

2820-12820 01/15 Operation Section 4-13

OPERATION

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 1"

or less 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 oper-

ated 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.

IMPORTANT:

Adjust the leveling rods the same amount and

maintain equal tension in the rods. Improper adjust-

ment may cause rods to snap or bend. Retighten

the jamnuts after the deck pitch has been set. OPS-

8.1 Driveline Length Check

When fitting the mower to the tractor, the telescoping driveline must be inspected to ensure that at its most

compressed position, the profiles do not “bottom out”, and when at its farthest extended position, there is

sufficient engagement between the profiles to operate safely. At its shortest length, there must be at least a 1”

clearance between each profile end and opposite profile universal joint. At its farthest operating extension, a

minimum profile engagement of 6” must be maintained for a Constant Velocity (CV) tube type driveline and a

minimum engagement of 6” for non-CV solid shaft drivelines.

8. 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

output shaft, pull the driveline yoke collar back and

align the grooves and splines of the yoke with those

of the PTO shaft. Push the driveline yoke onto the

PTO shaft, release the locking collar, and position

the yoke until the locking collar balls are seated

onto the PTO shaft. Push and pull the driveline

back and forth several times to ensure a secure

attachment. OPS-R-0003_A

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.

(S3PT-17)

Before operating the Implement, check to make sure the Implement input driveline will not

bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates

the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out

can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and

through the support bearings or downward onto the PTO shaft, breaking it off. A broken

driveline can cause personal injury.

(S3PT-18)

OPERATION

2820-12820 01/15 Operation Section 4-15

OPERATION

NOTE: If tractor has a 540 RPM PTO, adjusting to a 16 inch position will gain additional 2 inches of telescoping

length.

“Bottoming Out” Check Procedure

• Disconnect driveline from the tractor and slide

the profiles together until fully compressed.

• Place a mark on the inner shield 1/8” from the

end of the outer shield and reattach the

driveline to the PTO shaft.

• With the PTO NOT TURNING, slowly drive the

tractor with mower attached through the

sharpest turn possible and watch shaft

movement. With the PTO NOT TURNING,

slowly drive the tractor with the mower attached

through the most severe terrain conditions

expected and watch shaft movement.

• If the distance between the mark and the outer

shield becomes less than 2” at any point there is a potential problem bottoming out the driveline and the

driveline should be replaced with shorter driveline. Contact your local dealer or Technical Service for

proper directions. OPS-R-0004_J

Engagement Check Procedure

• With the driveline attached, position the mower to the point where the telescoping driveline is at its maximum

extension. Completely shut down the tractor and secure in position.

• Mark the inner driveline shield 1/8” from the end of the outer shield.

• Disconnect the driveline from the tractor and separate the two driveline halves.

• Measure the distance from the mark to the end of the inner profile. This length is the amount the driveline profiles were

engaged.

• If the engaged length is less than 6”, the shaft is considered too short and should be replaced with a longer shaft.

Consult an authorized dealer to purchase the required driveline length.

NOTE: If the driveline cannot be shortened and still maintain the required profile engagement, the operator must be made

aware of terrain conditions and avoid situations which pose a potential problem to avoid damaging the driveline or move

drawbar to 16” or 20” position for required clearance. OPS-R-0005_O

OPERATION

2820-12820 01/15 Operation Section 4-16

OPERATION

8.2 Constant Velocity (CV) Driveline

For mowers equipped with a Constant Velocity (CV) driveline, the maximum turning angle between the tractor

and mower must be determined to ensure the joint angle does not over-extend which can cause CV joint

damage. Constant Velocity joints enable the driveline to operate smoothly with no vibrations and clattering at

angles up to 80°. Angles greater than 80° can result in mechanical damage to the CV joint and mower

driveline.

The Constant Velocity joint must be lubricated every 8 hours of operation as specified in the Maintenance

Section. Failure to properly lubricate the joint will result in accelerated wear and joint component failure.

CV Driveline Maximum Angle Check Procedure

• With the mower attached to the tractor and the driveline disconnected from the tractor PTO stub make

a hard left turn until there is approximately a 1" clearance between the left rear tractor tire and mower

frame or tongue.

• Stop and completely shut down the tractor. Place the tractor in Park and apply the Parking Brake before

dismounting.

• Check the CV joint at this maximum turning radius by holding the driveline yoke above the PTO shaft and

then angle the CV joint to its maximum angle. A minimum difference of 10 degrees between the center

line of the yoke and the PTO shaft must be maintained to ensure the joint will not be over angled. If the

joint cannot be angled at least 10°, there is a potential problem of over-angling the joint while making

sharp turns.

• Solutions: To ensure the joint is not damaged, check the following:

Check the drawbar length to ensure that it is at the proper length for the RPM speed of the mower.

Move the tractor rear tires wider apart to limit the tractor turning radius.

Position the mower at multiple angles and perform the above procedure. Determine the sharpest turning

radius that maintains a safe operating angle and note this position to the operator. OPS-R-0006_B

OPERATION

2820-12820 01/15 Operation Section 4-17

OPERATION

The Constant Velocity PTO driveline is HEAVY (70 lbs or greater) and Special Lifting

Procedures are recommended. Use lifting assistance such as mechanical assistance, two

people, and proper lifting techniques when connecting or installing the driveshaft to reduce

the possibility of back injuries.

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

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

in possible injury from the separated Driveline sections.

(SRM-04)

9. PRE-OPERATION INSPECTION AND SERVICE

Before each use, a pre-operation inspection and service of the implement and tractor must be performed.

This includes routine maintenance and scheduled lubrication, inspecting that all safety devices are equipped

and functional, and performing needed repairs. DO NOT operate the unit if the pre-operation inspection

reveals any condition affecting safe operation. Perform repairs and replacement of damaged and missing

parts as soon as noticed. By performing a thorough pre-operation inspection and service, valuable down time

and repair cost can be avoided. OPS-U-0029

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)

DO NOT allow any person under a folded wing unless wing is securely

locked up or supported. DO NOT approach the Implement unless the

Tractor is turned off and all motion has ceased. Never work under the

frame work, or any lifted component unless the implement is securely

supported or blocked up. A sudden or inadvertent fall by any of these

components could cause serious injury or even death.

(STI-03)

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.

Inspect blade pan and blade assembly for the following:

OPS-U-0031

OPERATION

2820-12820 01/15 Operation Section 4-23

OPERATION

Operating the mower with loose blade hardware will damage the blade holder or blades and

can result in blade breakage or blade fastener failure. Broken blades or bolts can be thrown

out from under the mower for distances up to 300 feet. When the blades are replaced, the

fastening hardware must be replaced. Check and retighten the blade hardware after the first

eight hours of operation. In severe cutting conditions, recheck the blade carrier and blade

bolt torque every 50 hours.

To help prevent structural damage caused by loose hardware, tighten gearbox mounting

hardware as specified. Check the fastener torque after first 8 hours of use and every 50

hours thereafter.

Inspect the Blades daily for abnormal wear. REPLACE BOTH BLADES on that carrier

IMMEDIATELY if either blade has:

• Become bent or deformed from it’s original shape or

• Any cracks are visible, or

• Deep gouges in the blade’s surface are present, or

• Gouges or chipped areas in the cutting edge are larger than 1/2”(12.7mm), or

• The material on the leading edge has been worn away by more than 1/2(12.7mm)”

10. 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

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)

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)

OPERATION

2820-12820 01/15 Operation Section 4-28

OPERATION

10.1 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

10.2 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.

10.3 Operating the Mower Wings

Wings are positioned with hydraulic cylinders. It is recommended that the tractor be equipped with three

hydraulic ports or a 3-spool control valve be used so that each section can be controlled independently.

Ensure the hydraulic cylinders and lines are filled with oil by holding the valve control levers in the raised

position until the cylinders fully retract (wings) and extend (center). Only operate the mower with both wings

fully lowered, NEVER operate the mower with a raised wing. Wait until the blades are at a complete stop

before raising wings. OPS-R-0015

OPERATION

2820-12820 01/15 Operation Section 4-29

OPERATION

10.4 Transport Position

To raise mower wings, drive the unit to a level area

and retract the wing hydraulic cylinders. DO NOT

raise wings with the mower positioned on an

embankment or other inclined position to prevent

overturning the mower. After the wings are fully

raised, install transport lock pins to prevent wings

from inadvertently falling. NOTE: If the transport

lock pins can not be easily installed, lower the

mower wings and remove rod end of cylinder and

adjust the rod clevis in or out to match the transport

lock pins.

The center of gravity is raised and the mower more

prone to tipping when the wings are in the raised

position. When transporting, raise the center

section high enough to clear ground obstacles.

OPS-R-0016_F

When the Wings are folded for transport, the center of gravity is raised and the possibility of

overturn is increased. Drive slowly and use extreme caution when turning on hillsides.

Overturning the Implement could cause the Implement to overturn the Tractor and vice

versa resulting in serious injury or even death. Never fold wings on a hillside...the

Implement or unit may overturn.

(STI-02)

10.5 Operating Position

To lower the wings, remove the transport lock pins

and secure pins on storage bracket. DO NOT drive

out transport lock pins. The wing cylinder may need

to be retracted to remove tension for lock pin

removal. After removing lock pins, extend wing

hydraulic cylinders and fully lower wings.

The valves operating wing cylinders should be

placed in the float position while mowing to allow the

mower to follow the contour of uneven terrain and to

prevent the wings from creeping up. When

extending a wing over a ditch for mowing, place the

control valve lever detents in the center position.

This will give the mower more stability and prevent

the opposite wing from raising. DO NOT operate

the mower with the valves in the detent position for

extended periods of time to prevent deck frame

damage. OPS-R-0017_G

OPERATION

2820-12820 01/15 Operation Section 4-30

OPERATION

Use extreme care when lowering or unfolding the implement’s wings. Make sure no

bystanders are close by or underneath the wings. Allow ample clearance around the

implement when folding or unfolding the wings. Use extreme caution around buildings or

overhead power lines.

(S3PT-05)

10.6 Driving the Tractor and Cutter

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.

Drive the tractor with the 3-Point lift arms in the raised position and lock the control lever in the transport detent

position to prevent damage to the mower driveline and tongue when turning.

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-0018

OPERATION

2820-12820 01/15 Operation Section 4-31

OPERATION

10.7 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

2820-12820 01/15 Operation Section 4-32

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

11. 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

2820-12820 01/15 Operation Section 4-33

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)

11.1 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

11.2 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

2820-12820 01/15 Operation Section 4-34

OPERATION

Rotary Mowers are capable under adverse conditions of throwing

objects for great distances (300 ft (100 m) or more) and causing serious

injury or death. Follow safety messages carefully.

STOP MOWING IF PASSERSBY ARE WITHIN 300 Feet (100 m) 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)

11.3 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 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)

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)

OPERATION

2820-12820 01/15 Operation Section 4-35

OPERATION

11.5 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 cab.

The mower is designed to cut vegetation up to 3”(76.2mm) 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. Check tire

spacing as noted in Tractor Operators Manual.

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

11.4 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)

OPERATION

2820-12820 01/15 Operation Section 4-36

OPERATION

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

closed.

(SGM-11)

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 maneuvering 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)

OPERATION

2820-12820 01/15 Operation Section 4-37

OPERATION

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. NEVER raise the

mower wings while the blades are turning.

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.

If the mower is operated in conditions that require

frequent sharp turning, the mower should be

equipped with a Constant Velocity driveline. CV

joints enable the tractor PTO shaft and mower

driveline to be angled safely up to 80 degrees with

no damage to the mower or driveline. OPS-R-0027

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)

Stay alert and watch for trees, low hanging limbs,

power lines, and other overhead obstacles and solid

ground objects while you are operating. Use care

to avoid hitting these items

OPERATION

2820-12820 01/15 Operation Section 4-38

OPERATION

When mowing across uneven areas such as road shoulders, ditch edges, and other uneven terrain, position

mower so that one support wheel is near the highest point to prevent blades from cutting into gravel or dirt

which can cause rapid blade wear and extremely severe shock loads on the drivetrain resulting in rapid wear

or damage to these components. Blades contacting the ground may cause objects to be thrown out from

under the mower deck. Always avoid operating the mower at a height or position which may cause the blades

to contact the ground. Cutting into the berm or edge of the ditch will cause abnormal and accelerated blade

wear and possible blade component failure. OPS-R-0029

11.6 Right of Way (Highway) Mowing

• USE DOUBLE CHAIN GUARDS for highway, right-of-way, parks, greenbelt mowing, or all other mowing

where human dwellings, vehicles, or livestock could be within 300 feet of the mower.

• No shielding is 100% effective in preventing thrown objects. To Reduce Possibility of Injury:

1. MAINTAIN MOWER SHIELDING in good operational condition,

2. DAILY INSPECT the condition of the Thrown Object Guards, mower Side Skirts, and skid shoes:

Replace or repair worn or damaged guards.

3. DAILY INSPECT the condition of the Blades and Blade Bolts. Replace any cracked, worn, bent or

damage blades. Always replace blade bolts and nuts when replacing blades. Make sure the blade

bolts are properly tightened.

4. RAISE CUTTING HEIGHT to 6 INCHES minimum.

5. INSPECT AREA thoroughly before mowing to REMOVE potential THROWN OBJECT HAZARDS.

6. NEVER ALLOW BLADES to CONTACT SOLID OBJECTS like wire, rocks, posts, curbs, guardrails,

or ground while mowing.

ROTARY MOWERS CAN THROW OBJECTS 300 FEET OR MORE UNDER ADVERSE

CONDITIONS.

TO AVOID SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS FROM THROWN

OBJECTS:

INSPECT AREA FOR POTENTIAL THROWN OBJECTS BEFORE MOWING:

• REMOVE debris, rocks, wire, cable, metal objects and other foreign material from area.

Wire, cable, rope, chains and metal objects can be thrown or swung outside deck with great velocity:

1. MARK objects that cannot be removed.

2. AVOID these objects when mowing.

STOP MOWING IF PASSERSBY IS WITHIN 300 FEET UNLESS:

• All THROWN OBJECT SHIELDING including Front and Rear Deflectors, Chain Guards, Steel Guards,

Bands, Side Skirts and Skid Shoes are in place and in good condition when mowing.

• Mower sections or wings are adjusted to be close and parallel to ground without exposing blades.

• MOWING AREA has been inspected and foreign materials and debris have been removed.

11.7 Shutting Down the Implement

To shut down attached mower head, first bring the

tractor to a complete stop. Decrease engine RPM

to idle then disengage cutterhead. The mower head

will come to a complete stop within a suitable

amount of time. Do not engage or disengage the

cutterheads at a high RPM unless there is an

emergency situation.

Park the tractor on a level surface, place the

transmission in park or neutral and apply the

parking brake, lower the attached implement to the

ground, shut down the engine, remove the key, and

wait for all motion to come to a complete stop

before exiting the tractor. OPS-U- 0016

12. DISCONNECTING THE MOWER FROM THE TRACTOR

Before disconnecting the mower, the PTO must be disengaged and blade rotation at a complete stop. Move

the mower to a level storage location and lower the center section and both wings to the ground. If the mower

will be stored with the wings in the raised position, install both wing transport lock pins. If the mower is not

resting securely on the ground, block the mower up securely before attempting to disconnect it from the

tractor.

Use extreme care to keep feet and hands from under the mower and clear of any pinch points.

OPS-R-0030_G

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

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

and Tractor hitches.

OPERATION

2820-12820 01/15 Operation Section 4-41

OPERATION

Never unhitch without using the Tongue Jack. The Tongue is very heavy. Attempting to lift

the Tongue without using the Tongue Jack could cause strains or other injury. Allowing the

tongue to fall suddenly and unexpectedly could result in crushing injury. Use the Tongue

Jack for lifting the Implement only. Overloading the Tongue Jack can cause failure with

possible serious bodily injury or even death.

(STI-04)

When disconnecting the mower the tractor should

be completely shut down and secured in position.

Relieve hydraulic pressure by moving the control

levers back and forth several times. Lower the

parking jack and raise the mower until the tongue

clevis is no longer resting on the tractor drawbar

and is supported solely by the jack. The jack

should be in a near vertical position with the

ground and can be adjusted by loosening the

positioning nut and moving the jack up to 15

degrees in each direction. Also make sure that

the jack foot is securely resting at ground level or

securely supported by a block before raising the

mower. Once the mower tongue is being

supported entirely by the jack, remove the hitch

bolt, locknut, and washers. Remove the hydraulic

hoses from the tractor and secure to the mower to

prevent contact with dirt.

After disconnecting the mower hitch, remove the

mower driveline from the tractor PTO shaft. Place

the driveline in its storage bracket to prevent it

from contacting mud or dirt which can contaminate

the universal joint bearings and shorten the life of

the driveline.

After the driveline has been removed from the

tractor, place the PTO master shield back in the

operating position. OPS-R-0031

OPERATION

2820-12820 01/15 Operation Section 4-42

OPERATION

13. MOWER STORAGE

It is recommended that the mower be stored with the center section and both wings fully lowered to ground

level. If the mower is stored with the wings in the raised position, select a level area and install wing transport

lock pins to prevent the wings from falling BEFORE disconnecting the mower hitch from the tractor.

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_H

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

the Equipment and be injured or killed. Inadvertent contact with controls can cause the

Implement to shift or fall crushing themselves or others.

(SG-25)

14. TRANSPORTING THE TRACTOR AND IMPLEMENT

Inherent hazards of operating the tractor and implement and the possibility of accidents are not left behind

when you finish working in an area. Therefore, the operator must employ good judgement and safe operation

practices when transporting the tractor and implement between locations. By using good judgement and

following safe transport procedures, the possibility of accidents while moving between locations can be

substantially minimized. OPS-U- 0017

OPERATION

2820-12820 01/15 Operation Section 4-43

OPERATION

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

Falling off can result in serious injury or death.

(SG-10)

Before transporting the tractor and mower, idle the

tractor engine, disengage the PTO and wait for all

mower moving parts to come to a complete stop.

Once all mower parts are completely stopped, raise

the mower to transport height. NOTE: When

raising the mower, maintain at least 1” clearance

between the driveline and mower deck. If additional

mower deck height is needed for safe transport,

disconnect the driveline from the tractor and secure

its end to the mower deck. The mower can then be

raised to the maximum lift height. OPS-R-0033

If the tractor’s hydraulic pump is not independent of

the tractor PTO, or if the tractor PTO has to be run

to have hydraulic power, disconnect the mower

driveline from the tractor PTO output shaft. Secure

the driveline to the mower deck to prevent driveline

damage or loss during transport. OPS-R-0034

Before transporting the tractor on a public roadway

or boarding a trailer for transport, the tractor brake

pedals should be locked together. Locking the

pedals ensures that both wheels brake

simultaneously while stopping, especially when

making an emergency stop.

Use extreme caution and avoid hard applications of

the tractor brakes when towing heavy loads at road

speeds. Never tow the implement at speeds

greater than 20 MPH (32 kph). OPS-U- 0018

Tire Size and Matching requirements - Center Axle

Tire assemblies when mounted on center axle duals should always be within limits listed.

Laminated Tires - Maximum difference between tire diameters on a center axle should be 1/2 inch or less.

Foam Filled Airplane Tires - Maximum difference between tire diameters on a center axle should be 1 inch or

less.

When replacing a tire assembly on center axle always check diameters to make sure tires fall within allowed

range for maximum tire and wheel life. It may be necessary to move one or more tires from wing axles to

remain within size limit.

14.1 Tire and Wheels

Laminated Sectional Tires are designed for conditions where puncture proof performance is required and

the mower will not be transported for long distances on roadways. Transport speed for laminated tires should

not exceed 15 MPH. Excessive speed can cause damage to the machine and tire sections. Laminated tires

must be installed such that the rubber segments lay with the ground.

Foam Filled used Airplane Tires are ideal for conditions where a puncture proof tire is needed and the

mower is frequently transported between locations. OPS-R-0035_D

14.2 Transporting on Public Roadways

Extreme caution should be used when transporting the tractor and mower 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, flex arm and mower before

entering a public road. Secure the center section at a safe transport height by placing additional stroke control

spacers on the center axle cylinder and then lower the mower. Secure the mower wings in the raised position

with the transport lock pins. OPS-R-0036_E

Only tow the Implement behind a properly sized and equipped Tractor

which exceeds the weight of the Implement by at least 20%. DO NOT

tow the Implement behind a truck or other type of vehicle. Never tow the

Implement and another Implement connected in tandem. Never tow the

Implement at speeds over 20 MPH.

(STI-06)

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

Falling off can result in serious injury or death.

14.4 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

load.
