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.

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

only when the Tractor and all movin g parts are completely stopped.

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

(SG-11)

(SG-12)

ever work under the Implement, the framework, or any component unless the Implement is securely supported or blocked up to prevent sudden or inadvertent falling which could cause serious injury or even death.

(SG-14)

The operator and all support personnel should wear hard hats, safety shoes, safety glasses, and proper hearing protection at all times for

protection from injury including injury from items that may be thrown by the equipment.

(SG-16)

PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE PERMANENT HEARING LOSS! Tractors with or without an Implement

attached can often be noisy enough to cause perman ent hear ing lo ss. We recommend that you always wear hearing protection if the noise in the Operator’s position exceeds 80db. Noise over 85db over an extended period of time will cause severe hearing loss. Noise over 90db adjacent to the Operator over an extended pe riod of time will cause per manent or total hearing loss. NOTE: Hearing loss from loud no ise [from tracto rs, chain saws, rad ios,

and other such sources close to the ear] is cu mulative over a lifetime withou t hope of natural recovery.

(SG-I7)

GR60/72 02/07 Safety Section 1-4

SAFETY

Periodically inspect all moving parts for wear and replace when necessary with authorized service parts. Look for loose fasteners, worn or broken parts, and leaky or loose fittings. Make sure all pins have cotter pins and washers. Serious injury may occur from not maintaining this machine in good working order.

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:

(SG-21)

SAFETY

• 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 towing this equipment.

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

after you determine that it is safe to operate 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 safe 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 r educe your speed. Be aware of traf fic around you and watch out for the other guy.

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

motion or while tractor engine is running. Make sure the tractor engine is off, the

transmission in park, the parking brake set, and that the key is with you before working on

(SG-25)

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

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

(SG-26)

NEVER use drugs or alcohol immediately before or while operating the Tractor and Implement. Drugs and alcohol will affect an operator’s

alertness and coordination and therefore affect the operator’s ability to operate the equipment safely. Before operating the Tractor or Implement, an operator on prescription or over-the-counter medication must consult a medical professional regarding any side effects of the medication that would hinder their ability to operate the Equipment safely. NEVER knowingly allow anyone to operate this equipment when their alertness or coordination is impaired. operator is under the influence of drugs or alcohol.

Mower. REMEMBER! This machine is often operated in heavy brush and in heavy weeds. The Blades of this Mower can throw objects if shields are not properly installed and maintained. Serious injury or even death may occur unless care is taken to insure the safety of the operator, bystanders, or passersby in the area. Do not operate this machine with anyone in the immediate area. Stop mowing if anyone is within 100 yards of mower.

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-7)

GR60/72 02/07 Safety Section 1-7

SAFETY

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

persons behind the mower and use extreme care when mowing in reverse. Mow only at a slow ground speed where you can safely operate and control the tractor and mower. Never mow an area that you have not inspected and removed debris or foreign material.

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-10)

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

including clearance or for turning. Raising the Mower deck exposes the Cutting Blades which creates a potentially serious hazard and could cause serious injury or even death from objects thrown from the Blades.

(SRM-7)

(SGM-8)

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

position. Accidental operation of lifting lever or a hydraulic failure may cause sudden drop of unit with injury or death by crushing. To properly park the implement when disconnecting it from the tractor, lower the stand and put the retaining pin se cure ly in place, or put a secure su pport un der th e A-Fram e. Lower the implement carefully to the ground. Do not put hands or feet under lifted components.

(S3PT-1)

GR60/72 02/07 Safety Section 1-8

SAFETY

Rotary Mowers are capable under adverse conditions of throwing objects for great distances (300 feet or more) and causing serious injury

or death. Follow safety messages carefully.

STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:

-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable condition;

-Mower sections or Wings are running close to and parallel to the ground without exposed Blades;

-Passersby are outside the existing thrown-object zone;

-All areas have been thoroughly inspected and all foreign material such as rocks, cans, glass, and general debris has been removed.

NOTE: Where there are grass and weeds high enough to hide debris that could be struck by the blades, the area should be: inspected and large debris removed, mowed at an intermediate height, inspected, closely with any remaining debris being removed, and mowed again at desired final height. (This will also reduce power required to mow, reduce wear and tear on the Mower drivetrain, spread cut material better, eliminate streaking, and make the final cut more uniform).

(SRM-1)

SAFETY

Be particularly careful when transporting the Implement with the Tractor. Turn curves or go

up hills only at a low speed and using a gradual steering angle. Rear mounted implements

move the center of gravity to the rear and remove weight from the front wheels. Make certain, by adding fron ballast, that at least 20% of the tractor’s weight is on the front wheels to prevent rearing up, loss of steering control or Tractor tip-over. Slow down on rough or uneven surfaces to prev ent loss of st eering co ntrol w hich could result in property damage or possible injury. Do not transport unless 3-Point lift lever is fully raised and in the latched transport position. Dropping implement in transport can cause serious damage to the tracto and/or Implement and possibly cause the operator or others to be injured or killed. (S3PT-2)

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

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

terrain conditions that include tall grass, weeds, gullies, holes, slopes, hidden obstructions and the like. Serious injury or even death may occur unless care is taken to assure the safety of the operator and bystanders in the area. Do not operate this machine with anyone in the immediate area.

INTRODUCTION

These rugged Cutters are designed for heavy-duty work. They can mow pastures, cut brush up to 3" (GR60) and 4" (GR72) in diameter, and control grass and weeds on highways or industrial sites.

For Non-Agricultural use, OSHA, ASAE, SAE, and ANSI standards require the use of Chain Guards or Solid Skirts at all times. The Cutter manufacturer strongly recommends the use of Chain Guards or Solid Skirts for Agricultural purposes as well, to reduce the risk of property damage, serious bodily injury, or even death from objects thrown out by or from contact with the Cutting Blades.

The 60" machine requires a minimum of 30 HP for both 540 and 1000 RPM ma chines. The 72" Cutter req uires at least 35 HP for 540 and 1000 RPM machines. The maximum allowable horsepower for either size is 120HP.

At least 20% or the tractor’s weight must be on the front tires with the implement lifted to provide adequate traction for safe steering under good conditions. Slow down on hills, rough terrain, and curves.

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

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 20-spline, 1-3/4” shaft. Refer

to the tractor owner’s manual for instructions to chan ge 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

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 Mower resulting in excessive vibration, thrown objects, and blade and mower 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)

OPERATION

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 )

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 the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all movin g parts are completely stopped.

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 t ractor. Review the tractor operator’s manual and consult an authorized dealer for tractor operation instructions if needed.

Essential Tractor Controls:

• Locate the light control lever.

• 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.

OPERATION

Never run the Tractor engine in a closed building or without adequate ventilation. The exhaust fumes can be hazardous to your health.

Start tractor only when properly seated in the Tractor seat. Starting a

tractor in gear can result in injury or death. Read the Tractor operators

manual for proper starting instructions.

(SG-13)

(SG-23)

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

GR60/72 02/07 Operation Section 4-9

OPERATION

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.

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 3point lift arms positioned between the respective set of mower A-frame lift lugs.

NOTE: Set the 3-point lift control to “Position Control” so that the lift arms maintain a constant height when attaching the mower.

OPERATION

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.

(S3PT-15)

NOTE: Offset Adaptor Hitches are availa ble to position the mower to the left or right. Mowers with Offse t Adaptor hitches connect to the 3-Point hitch the same way as the mower A-frame. See Offset Ada ptor Hitch in the Assembly Section for details to equip the mower with this feature.

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 und er the mower deck. Always avoid operating the mower at a height which causes the blades to contact the ground. OPS-U- 0010

GR60/72 02/07 Operation Section 4-10

OPERATION

7.1 Setting Mower Height

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. Level the mower deck front to rear by extending or retracting the 3-point top link.

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 positioning bracket to the support brackets and allow the tailwheel to rest at ground level. Align beam and positioning brackets holes with closest set of holes in support brackets and reinstall bolts securing the beam in position. Tighten all bolts and nuts.

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.

OPERATION

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.

ng Deck

To facilitate safe and efficient operation, the mower should be operated with the deck approximately 3/4” LOWER IN THE FRONT THAN THE REAR. The correct deck pitch is obtained as follows:

1. Lower the mower until the rear of the mower is resting securely on its tail wheel.

2. Then slowly lower the 3-point lift arms further until the front of the mower is at least 3/4” lower than the rear of the mower.

3. Place the tractor’s 3-point con trol lever stop at this position so that each time the mower is raised and lowered the deck pitch will be maintained.

Operating the mower with the front of the deck slightly lower than the rear allows the mower to cut the grass

OPERATION

only once and requires less work from the tractor. In addition, a more even distribution of the clippings from the rear of the mower will be achieved with this angle. OPS-R-0002_B

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

8.1 Driveline Length Check

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 drive line can cause personal injury.

(S3PT-18)

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 9” must be maintained.

ng 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.

• Reattach the driveline to the PTO Shaft.

• Raise the mower and watch the driveline as it

approaches the mark. If the distance between the mark and the end of the outer shield tube becomes less than 2” at any point, the driveline must be shortened. OPS-R-0004_A

OPERATION

GR60/72 02/07 Operation Section 4-13

OPERATION

GR60 Mowers Only

Shorten the driveline profiles as follows:

• Remove the driveline from the tractor.

• Raise and lower the mower to find the position

with the shortest distance between the tractor PTO shaft and cutter gearbox. Shut down the tractor and securely block the mower in this position.

• Pull driveline apart and reattach yoke to PTO

shaft.

• Hold driveline sections parallel to one another

and measure back 1” from yoke of each shaft and place mark on opposite section. Cut this length off with a saw.

• Round off all sharp edges and debur.

• Thoroughly grease then reinstall the driveline.

• Recheck for proper operation.

OPERATION

GR72 Mowers

The GR72 driveline is a bar and welded sleeve assembly and its length cannot be modified as described above. Contact your authorized dealer or Rhino Customer Service for recommendations to fit the mower to the tractor if there is a potential problem bottoming out the driveline.

Engagement Check Procedure

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

maximum extension. Turn off the tractor and securely block the mower at this 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 mar k to th e e nd of the inner profile. This length is the amount the driveline

profiles were engaged.

• If the engaged length is less than 9”, 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: When raising the mower, at least 1” clearance must be maintained between the driveline and the mower deck. If necessary, place an upper lift stop on the 3-point hitch control lever to limit the height the mower can be raised. OPS-R-0005_B

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 PT O d riveline connected a nd running. Rotating Parts, Blades or Drivelines could turn without warning and cause immediate entanglement, injury or death.
