DANGER!

WARNING!

CAUTION! PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE PER-

Do not operate this Equipment with hydraulic oil leaking. Oil is expensive and its presence could present a hazard. Do not check for leaks with your hand! Use a piece of heavy paper or cardboard. Highpressure oil streams from breaks in the line could penetrate the skin and cause tissue damage including gangrene. If oil does penetrate the skin, have the injury treated immediately by a physician knowledgeable and skilled in this procedure. (SG-15)

The operator and all support personnel should wear hard hats, safety shoes, safety glasses, and proper hearing protection at all times for protection from injury including injury from items thrown by the equipment. (SG-16)

MANENT HEARING LOSS! Tractors with or without an Implement attached can often be noisy enough to cause permanent hearing loss. We recommend that you always wear hearing protection if the noise in the Operator’s position exceeds 80db. Noise over 85db over an extended period of time will cause severe hearing loss. Noise over 90db adjacent to the Operator over an extended period of time will cause permanent or total hearing loss. Note: Hearing loss from loud noise [from tractors, chain saws, radios, and other such sources close to the ear] is cumulative over a lifetime without hope of natural recovery. (SG-I7)

SAFETY

WARNING! Transport only at safe speeds. Serious accidents and injuries can re-

sult from operating this equipment at unsafe 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 safe 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 safe transport speed for you and 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 that you

have determined are safe and which allow you to properly control the equipment.

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. When operating in traffic always use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you andwatch out for the other guy. (SG-19)

SAFETY

WARNING!

DANGER!

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 before working on the Implement.

(SG-20)

Periodically inspect all moving parts for wear and replace when necessary with authorized service parts. Look for loose fasteners, worn or broken parts, and leaky or loose fittings. Make sure all pins have cotter pins and washers. Serious injury may occur from not maintaining this machine in good working order. (SG-21)

Always read carefully and comply fully with the manufacturers instructions when handling oil, solvents, cleansers, and any other chemical agent. (SG-22)

Never run the tractor engine in a closed building or without adequate ventilation. The exhaust fumes can be hazardous to your health. (SG-23)

DANGER!

KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement and possible serious injury or death.

(SG-24)

Never allow children to play on or around Tractor or Implement. Children can slip or fall off the Equipment and be injured or killed. Children can cause the Implement to shift or fall crushing themselves or others. (SG-25)

Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause Implement driveline or blade failures resulting in serious injury or death.

(SG-26)

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

Serious injury or

death to the operator or others could result if the operator is under the influence of drugs or alcohol. (SG-27)

DANGER! Operate the Tractor and/or Implement controls only while properly seated in the Tractor seat with

the seat belt securely fastened around you. Inadvertent movement of the Tractor or Implement may cause serious injury or death. (SG-29)

WARNING!

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 100 yards 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 this type of items discontinue mowing. (SGM-

DANGER!

There are obvious and hidden potential hazards in the operation of this Mower. REMEMBER! This machine is often operated in heavy brush and in heavy weeds. The Blades of this Mower can throw objects if shields are not properly installed and maintained. Serious injury or even death may occur unless care is taken to insure the safety of the operator, bystanders, or passersby in the area. Do not operate this machine with anyone in the immediate area. Stop mowing if anyone is within 100 yards of mower. (SGM-2)

Safety Section 1-6LJ60/72 02-02

Page 13

SAFETY

DANGER! All Safety Shields, Guards and Safety devices including

(but not limited to) - the Deflectors, Chain Guards, Steel Guards, Gearbox Shields, Hydraulic Tank Shields, and Retractable Door Shields should be used and maintained in good working condition. All safety devices should be inspected carefully at least daily for missing or broken components. Missing, broken, or worn items must be replaced at once to reduce the possibility of injury or death from thrown objects, entanglement, or blade contact. (SGM-3)

SAFETY

DANGER!

WARNING!

The rotating parts of this machine have been designed and tested for rugged use. However, they could fail upon impact with heavy, solid objects such as steel guard rails and concrete abutments. Such impact could cause the broken objects to be thrown outward at very high velocities. To reduce the possibility of property damage, serious injury, or even death, never allow the cutting blades to contact such obstacles. (SGM-4)

Extreme care should be taken when operating near loose objects such as gravel, rocks, wire, and other debris. Inspect the area before mowing. Foreign objects should be removed from the site to prevent machine damage and/or bodily injury or even death. Any objects that cannot be removed must be clearly marked and carefully avoided by the operator. Stop mowing immediately if blades strike a foreign object. Repair all damage and make certain rotor or blade carrier is balanced before resuming mowing. (SGM-5)

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-6)

Mow at the speed that you can safely operate and control the tractor and mower. Safe mowing speed depends on terrain condition and grass type, density, and height of cut. Normal ground speed range is from 0 to 5 mph. Use slow mowing speeds when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power lines, or when debris and foreign objects are to be avoided. (SGM-7)

WARNING!

Avoid mowing in reverse direction when possible. Check to make sure there are no persons are 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 in the reverse direction that you have not inspected and removed debris or foreign material. (SGM-

Do not put hands or feet under mower decks. Blade Contact can result serious injury or even death. (SGM-9)

SAFETY

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

BLADES SINCE THIS WILL LIKELY CRACK OR OTHERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLE SERIOUS INJURY FROM THROWN BLADES. (SGM-10)

WARNING!

SAFETY

DANGER!

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

(SGM-11)

Rotary Mowers are capable under adverse conditions of throwing objects for great distances (100 yards 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 requiredto mow, reduce wear and tear on the Mower drivetrain, spread cut material better, eliminate streaking, and make the final cut more uniform.)

(SRM-1)

WARNING!

Do not let the Blades turn when the Mower Deck is raised for any reason, including clearance or for turning. Raising the Mower deck exposes the Cutting Blades which creates a potentially serious hazard and could cause serious injury or even death from objects thrown from the Blades. (SRM-7)

Never leave Tractor and Implemented unattended while the implement is in the lifted position. Accidental operation of lifting lever or a hydraulic failure may cause sudden drop of unit with injury or death by crushing. To properly park the implement when disconnecting it from the tractor, lower the stand and put the retaining pin securely in place, or put a secure support under the AFrame. Lower the implement carefully to the ground. Do not put hands or feet under lifted components. (S3PT-1)

Be particularly careful when transporting the Implement with the Tractor. Turn curves or go up hills only at a low speed and using a gradual steering angle. Rear mounted implements move the center of gravity to the rear and remove weight from the front wheels. Make certain, by adding front ballast, that at least 20% of the tractor’s weight is on the front wheels to prevent rearing up, loss of steering control or Tractor tip-over. Slow down on rough or uneven surfaces

to prevent loss of steering control which could result in property damage or possible injury. Do

not transport unless 3-Point lift lever is fully raised and in the latched transport position. Dropping implement in transport can cause serious damage to the tractor and/or Implement and possibly cause the operator or others to be injured or killed. (S3PT-2)

SAFETY

DANGER!

WARNING!

There are obvious and hidden potential hazards in the operation of this Implement as in all power-driven or pulled equipment. REMEMBER! This machine is often operated in rough terrain conditions that include tall grass, weeds, gullies, holes, slopes, hidden obstructions and the like. Serious injury or even death may occur unless care is taken to assure the safety of the operator and bystanders in the area. Do not operate this machine with anyone in the immediate area. (S3PT-7)

Make sure the PTO shield is installed when using PTO-driven equipment. Always replace the PTO shield if it is damaged or missing. (S3PT-8)

Relieve hydraulic pressure prior to doing any maintenance or repair work on the Implement. Place the Implement on the ground or securely blocked up, disengage the PTO, and turn off the tractor engine. Push and pull the Remote Cylinder lever in and out several times prior to starting any maintenance or repair work. (S3PT-9)

SAFETY

WARNING!

DANGER!

The rotating parts of this machine continue to rotate even after the PTO has been turned off. The operator should remain in his seat for 60 seconds after the brake has been set, the PTO disengaged, the tractor turned off, and all evidence of rotation has ceased. (S3PT-10)

“Wait a minute...Save a life!”

Always disconnect the main PTO Driveline from the Tractor before performing service on the Implement. Never work on the Implement with the tractor PTO driveline connected and running. Rotating Parts, Blades or Drivelines could turn without warning and cause immediate entanglement, injury or death. (S3PT-11)

This Implement is 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.

LJ60/72 02-02 Operation Section 4-5

Page 80

OPERATION

2.3 Tractor Horsepower

The power required to operate a cutter is determined by the tractor PTO horsepower. For most cutting conditions, the LJ60 and LJ72 require a tractor with 50 and 90 HP, respectively. Operating the cutter with a tractor that does not have adequate power may damage the tractor engine. Exceeding 125 HP may cause cutter damage by overpowering the unit in heavy cutting conditions.

Top link attaches here

2.4 3-Point Hitch

Lumberjack cutters are considerably heavier than conventional rotary mowers of the same size. The tractor 3-point hitch must be rated to lift at least 1650 lbs. if attaching a LJ60 and 2500 lbs. if attaching a LJ72.

1-1/4 O.D. Bushing must be installed here.

The LJ60 attaches to tractors with a Cat II 3-point hitch and the LJ72 either a Cat II or III hitch. Refer to the tractor owner’s manual for the category of the tractor used. If the hitch does not conform to the ASAE Cat II or III hitch dimensions, the cutter may not fit properly. Consult an authorized dealer for possible modification procedures to mount nonconforming hitches.

Use the correct hitch pins for the hitch category being used. For a Cat II hitch, 1-1/8” lower and 1” upper diameter hitch pins are used and Cat III hitches require 1-7/16” lower and 1-1/4” upper diameter hitch pins.

A minimum of 20% total tractor weight must be maintained on the tractor front end when the cutter is in the raised position. Proper weight on the tractor front end is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the tractor 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.

LJ60/72 02-02 Operation Section 4-6

Page 81

OPERATION

2.6 Power Take Off (PTO)

Depending on the equipped gearbox, LJ60/72 cutters are designed to operate at either 540 or 1000 rpm. Most tractors operate at either 540, or a combination of 540 and 1000 rpm PTO speeds. The speed of the tractor PTO can be determined by the number of splines on the PTO output shaft. Those operating at 540 rpm will have a 6spline 1-3/8” diameter shaft and those operating at 1000 rpm will have a 21-spline 1-3/8” shaft. NOTE: The LJ60/72 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 change PTO speeds on models that operate at more than one speed.

WARNING!

Never use a PTO shaft adapter to connect a Mower to a Tractor which operate at different speeds. The Mower must be operated by the Tractor at its rated speed (depending on mower either 540 or 1000 rpm) to provide a specfic blade speed for efficient and safe mowing. Attaching a non-conforming tractor PTO shaft to an Implement driveline using a PTO shaft adapter will result in the Implement operating at a greatly increased or reduced speed. Use of a PTO shaft apapter will also change the working length of the driveline and expose unshielded driveline areas. Serious bodily injury and/or equipment failure can result from combining non-conforming Tractor and Implement speeds with the use of an adapter. Consult an authorized dealer for technical assistance if the Tractor and Mower are designed to operate at different speeds.

3. GETTING ON AND OFF THE TRACTOR

Before getting onto the tractor, the operator must read and completely understand the cutter and tractor operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for a complete explanation.

OPERATION

6. SETTING THE CUTTER

Properly setting the cutter height is essential for efficient and safe operation. A properly set cutter 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 cutter and drive

6.1 Setting Cutting Height

1. Park the tractor and cutter on level ground.

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

3. Shut down the tractor and remove the key.

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

5. Level the cutter 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 cutter at this height.

7. Remove the bolts securing the tailwheel beam in position and allow the tailwheel to rest at ground level. Align tailwheel beam between nearest sets of holes in beam support brackets and reinstall support bolts on each side of beam. Tighten all bolts and nuts.

8. Extend the tractor’s top 3-point link so that when lifting the cutter, the front of the deck will raise 2 to 2½" before the tail wheel leaves the ground. This will allow the cutter to follow the contour of uneven

terrain.

OPERATION

6.2 Setting Deck Level

The cutter deck should be level from front to rear and side to side. It is especially important that the cutter be level with the ground when cutting large diameter trees. If the cutter is not level, the blades are making contact with the tree on an elevated angle, and its ability to cut is greatly reduced. There is extreme pressure being applied to the blades, the blade carrier, the gearbox, and the driveline when cutting large diameter size trees. This pressure can cause the blades to bend or break, and other component failure. By minimizing the work required by the cutter and tractor, better performance and increased longevity of the

tractor and cutter can be realized

The cutter deck should be level with the ground to reduce the work required by the cutter and tractor and to minimize equipment wear and damage.

7. DRIVELINE ATTACHMENT

The driveline yoke and tractor PTO shaft must be dirt free and greased for attachment.

To attach the driveline, loosen the driveline yoke clamping cone with a 11/16” (17mm) wrench and remove the cone from yoke. Slide yoke onto output shaft and align hole for cone with groove of PTO output shaft. Reinstall cone and tighten (50 lb-ft torque). Push and

OPERATION

pull the driveline to ensure it is securely attached to PTO output shaft. Regularly check the driveline yoke to ensure a tight connection. To remove the yoke, remove the connecting cone and pull yoke off the output shaft. If the cone cannot be easily removed by hand, drive it out from the other side using a hammer and

punch.

WARNING!

LJ60/72 02-02 Operation Section 4-12

When attaching the PTO yoke to the Tractor PTO shaft, it is important that the clamping cone is securely seated into the groove of the PTO shaft and properly tightened. A driveline not attached correctly to the Tractor PTO shaft could slip off and result in personal injury and damage to the cutter.

Page 87

OPERATION

7.1 Driveline Length Modification

WARNING!

When fitting the cutter 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 10” must be maintained.

“Bottoming Out” Check Procedure

1. Disconnect driveline from the tractor and slide the profiles together until fully compressed.

2. Place a mark on the inner shield 1/8” from the end of the outer shield.

3. Reattach the driveline to the PTO shaft.

4. Raise the cutter 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.

Before operating the Mower, check to make sure the 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.

OPERATION

Shorten the driveline profiles as follows:

1. Remove the driveline from the tractor.

2. Raise and lower the cutter to find position with the shortest distance between the tractor PTO shaft and cutter gearbox. Shut down the tractor and securely block the cutter in this position.

3. Pull driveline apart and reattach yoke to PTO shaft.

4. 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.

5. Round off all sharp edges and debur.

6. Thoroughly grease then reinstall the driveline.

7. Recheck for proper operation.

LJ60/72 02-02 Operation Section 4-13

Page 88

OPERATION

Engagement Check Procedure

1. With the driveline attached, raise and lower the cutter within its operating range. Position the mower at the point where the telescoping driveline is at its maximum extension. Turn off the tractor and apply the parking brake. Securely block the cutter at this height.

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

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

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

5. If the engaged length is less than 10”, 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 cutter, at least 1” clearance must be maintained between the driveline and the cutter deck. If necessary, place an upper lift stop on the 3-point hitch control lever to limit the height the cutter can be raised.

8. PRE-OPERATION INSPECTION AND SERVICE

Before each use, a pre-operation inspection and service of the cutter 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 cutter and tractor 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.

DANGER!

OPERATION

WARNING!

Always disconnect the main PTO Driveline from the Tractor before performing service on the Mower. Never work on the Mower with the Tractor PTO driveline connected and running. Blades or Drivelines could turn without warning and cause immediate

entanglement, injury or death. (SRM-3)

Never work under the Mower, the framework, or any lifted component unless the Mower is securely supported or blocked up to prevent sudden or inadvertent falling which could cause serious injury or

OPERATION

9. DRIVING THE TRACTOR AND CUTTER

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 cutter and the tractor operating controls are set for safe transport. To ensure safety while driving the tractor with an attached cutter, review the following.

DANGER!

WARNING!

OPERATION

Never run the Tractor engine in a closed building or without adequate ventilation. The exhaust fumes can be hazardous to your health. (SG-23)

Transport only at safe speeds. Serious accidents and injuries can result from operating equipment at unsafe speeds. Understand the Tractor and Mower 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 Mower, determine the safe transport speeds for you and the equipment. Make sure you abide by the following rules:

1. 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 Mower. As you increase the speed of the Tractor the stopping distance increases. Determine the maximum safe transport speed for you and this Equipment.

2. 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 Mower from turning over. Determine the maximum safe turning speed for you and this equipment before operating on roads or uneven ground.

3. Only transport the Tractor and Mower at the speeds that you have

determined are safe and which allow proper control of the equipment.

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. (SG-19)

LJ60/72 02-02 Operation Section 4-18

Page 93

OPERATION

9.1 Starting the Tractor

The procedure to start the tractor is model specific. Refer to the tractor operator’s manual for starting procedures for your particular tractor. Consult an authorized dealer if the starting procedure is unclear. Ensure the 3-point control lever is in the lowered position and the PTO lever is off before starting the tractor.

9.2 Brake and Differential Lock Setting

Make sure the tractor brakes are in good operating condition. Tractor brakes can be set to operate independently allowing single rear wheel braking action or locked together to provide simultaneous rear wheel braking. FOR MOST DRIVING AND CUTTING CONDITIONS, THE BRAKE PEDALS SHOULD BE LOCKED TOGETHER TO PROVIDE THE MOST EFFECTIVE BRAKING ACTION.

WARNING!

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.

OPERATION

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.

LJ60/72 02-02 Operation Section 4-19

Page 94

OPERATION

9.3 Raising the Cutter

Using the tractor 3-point hitch control lever, raise the cutter off the ground about 6”, or just high enough to clear any ground obstacles. When raising the cutter, make sure all connection points are securely attached and at least 1” clearance is maintained between the driveline and the deck. If necessary, place an upper lift stop on the 3point hitch control lever to limit the height the cutter can be raised to avoid driveline damage.

9.4 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 cutter. 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. If the tractor becomes stuck or the tires are frozen to the

ground, reverse the tractor out to prevent overturning.

Perform turns with the tractor and cutter at slow speeds to determine how the tractor with the cutter handles a turn. Determine the safe operating speed to maintain proper control of the tractor when making turns. When turning with an attached rear implement, the overall length of the working unit is greatly increased. Allow additional clearance for the cutter to swing when

OPERATION

turning.

WARNING!

Be particularly careful when transporting the Mower with the Tractor. Turn curves or go up hills only at a low speed and using a gradual steering angle. Rear mounted Implements move the center of gravity to the rear and remove weight from the front wheels. Make certain, by adding front ballast if necessary, to maintain at least 20% of the Tractor’s weight on the front wheels to prevent Tractor rearing up, loss of steering control, and possible Tractor tip-over. Slow down on rough or uneven surfaces to prevent loss of steering control, which could result in property damage or possible injury. Do not transport the Mower unless the Tractor 3-Point lift lever is fully raised and in the latched transport position. Dropping the Mower during transport can cause serious damage to the Tractor

and/or Mower, and possibly cause the operator or others to be injured or killed. (S3PT-2)

LJ60/72 02-02 Operation Section 4-20

Page 95

OPERATION

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.

9.5 Crossing Ditches and Steep Inclines

When crossing ditches with steep banks or going up sharp inclines, it is possible that the 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 may result in damage to the tractor and cutter components in the form of severe catastrophic failures.

OPERATION

WARNING!

When confronted with an incline or ditch, do not approach from an angle which is perpendicular or straight on as damage to over collapse of the driveline may occur.

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 as approach increases the possibility

of a tractor roll-over, select an alternate crossing path.

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

LJ60/72 02-02 Operation Section 4-21

OPERATION

10. OPERATING THE TRACTOR AND CUTTER

Before starting any cutting operation, the operator must become familiar with the area to be cut 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.

DANGER!

OPERATION

resuming mowing. (SGM-5)

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-6)

10.1 Foreign Debris Hazards

Before cutting, inspect the area to make sure there are no foreign objects that the cutter 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 cutter blades from contacting them.

LJ60/72 02-02 Operation Section 4-22

Page 97

OPERATION

If you hit a solid object or foreign debris, stop the cutter and tractor at once. Immediately idle the engine speed and disengage the PTO. Wait for all cutter rotating motion to stop, then raise the cutter 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 cutter 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 the ROPS in the raised position. If the tractor or cutter contacts a tree stump, rock, or bump, a sudden movement could throw you off of the seat and under the tractor and/or cutter. 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.

10.2 Bystander/Passersby Precautions

If a bystander comes within 100 yards of the tractor while the cutter 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 100 yard distance. If the cutter is operated in the vicinity of people or livestock, the cutter must be operated with front chain guards and the retractable rear guard in the lowered position.

DANGER!

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.

Rotary Mowers are capable under adverse conditions of throwing objects for great distances (100 yards or more) and causing serious injury or death. Follow safety messages carefully.

OPERATION

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 the 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)

LJ60/72 02-02 Operation Section 4-23

Page 98

OPERATION

10.3 Engaging the Power Take Off (PTO)

Before engaging the PTO, make certain that the area is clear of bystanders and passersby. 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 540 or 1000 rpm. If you hear unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the cutter to determine the cause of the noise or vibration and repair the abnormality.

DANGER!

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)

Do not put hands or feet under Mower decks. Blade contact can result in serious injury or even death. (SGM-9)

10.4 PTO RPM and Ground Speed

Ground speed for cutting will depend upon the height, type, and density of vegetation to be cut. Recommended speed for efficient cutter performance is between 1 and 3 mph. Operate the cutter at its rated 540 or 1000 rpm PTO speed to maintain blade speed and produce a clean cut. Refer to the tractor operator’s manual or the tractor

OPERATION

instrument panel for the engine speed and gear to provide the required PTO and desired speed. Make sure that the cutter is operating at its full rated speed before the blades make contact with vegetation. 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 cutter 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.

WARNING!

LJ60/72 02-02 Operation Section 4-24

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)

Page 99

OPERATION

WARNING!

Mow at the speed that you can safely operate and control the Tractor and Mower. Safe mowing speed depends on terrain condition and grass type, density, and height of cut. Normal ground speed range is from 1 to 3 mph. Use slow mowing speeds when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power lines, or when debris and foreign objects are to be avoided. (SGM-7)

10.5 Operating the Cutter

The cutter is designed to cut vegetative material up to 6” in diameter. The tractor and cutter can be operated by driving across growth that a properly rated tractor can safely pass over. This includes grass, brush, small trees and other type of growth up to about 3” in diameter.

To cut larger vegetation (up to 6” maximum diameter), raise the retractable rear guard and slowly back the cutter into the material. Use extreme care when backing the tractor and cutter. Allow the cutter sufficient time to cut through the material and maintain the operating speed to prevent overloading the cutter and tractor. Only raise the retractable rear guard while backing into areas to be cut. The guard must be maintained in the lowered position at

all other times.

OPERATION

DANGER!

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 100 yards 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 this type of item discontinue

mowing. (SGM-1)

Only mow where you have good visibility and can clearly see the ground and surrounding area that you are working in. Reduce speed when vision of the area is reduced or if you are avoiding foreign debris.

LJ60/72 02-02 Operation Section 4-25

Page 100

OPERATION

When you get to the end of a pass, slightly raise the cutter (2-4”) before turning. Never raise the cutter entirely while the blades are turning. If the cutter must be raised higher than 12” from ground level, disengage the tractor PTO and wait for all cutter rotation to come to a complete stop before proceeding to raise the cutter.

Large, dense, or wet vegetation may need to be cut in two or more passes to achieve a uniform cut. In such conditions, raise the cutting height to 12” or more on the first pass.

OPERATION

Then lower the cutting height of the cutter and cut the vegetation a second time. If possible, select a cutting pattern that is at a 90 degree angle to the first pass to reduce streaking and provide a more even cut.
