OPERATION SECTION Operation Section 4-1
OPERATION LUMBERJACK 60/72 HEAVY-DUTY TREE CUTTERS OPERATION INSTRUCTIONS Rhino Lumberjack 60 and Lumberjack 72 (LJ60/72) Heavy-Duty Tree Cutters are manufactured with quality material by skilled workers. Lumberjack cutters are engineered to cut vegetative material that a properly rated tractor can drive over (up to about 3” in diameter) and larger vegetation (up to 6” maximum diameter) by raising the retractable rear door and backing the cutter into the material.
OPERATION (7) DRIVELINE ATTACHMENT.................................................................................................................4-12 (7.1) Driveline Length Modification.....................................................................................................4-13 (8) PRE-OPERATION INSPECTION AND SERVICE.............................................................................4-14 (8.1) Tractor Pre-Operation Inspection/Service...................................................
OPERATION 1. OPERATOR REQUIREMENTS Safe operation of the Rhino Lumberjack 60 and Lumberjack 72 (LJ60/72) Heavy-Duty Tree Cutter is the responsibility of a qualified operator. A qualified operator has read and understands both the cutter and tractor Operator Manuals and is experienced in tractor and cutter operations and all associated safety practices. In addition to the safety messages contained in this manual, safety message decals are affixed to the cutter and tractor.
OPERATION 2. TRACTOR REQUIREMENTS The tractor used to operate the cutter must have the power capacity to lift, pull, and operate the Power Take Off (PTO) at the required speed (540 or 1000 revolutions per minute, depending on cutter gearbox) while traveling at a ground speed between 1 and 3 mph. Operating a cutter with a tractor that does not meet the following requirements may cause tractor or cutter damage and be a potential danger to the operator and passersby.
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.
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.
OPERATION 3.1 Boarding the Tractor Use both hands and equipped handrails and steps for support when getting on the tractor. Never use tractor control levers for support when mounting the tractor. Always seat yourself in the operator’s seat and fasten the seatbelt. Only operate the tractor and cutter with the ROPS in the raised position. Never allow passengers to ride on the tractor or cutter.
OPERATION 4. 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.
OPERATION 5. CONNECTING THE CUTTER TO THE TRACTOR Use extreme caution when connecting the cutter to the tractor. The cutter should be securely resting at ground level or setting securely on blocks. Keep hands and feet from under cutter deck and clear of pinch points between tractor hitch arms and cutter pins. DANGER! Never stand or allow another person to stand between a running Tractor and the Mower when attaching the Implement to the Tractor 3-point hitch.
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.
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.
OPERATION 7.1 Driveline Length Modification WARNING! 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 1. 2. 3. 4. 5. Engagement Check Procedure 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. Mark the inner shield 1/8” from the end of the outer shield. Disconnect the driveline from the tractor and separate the two driveline halves.
OPERATION 8.1 Tractor Pre-Operation Inspection/Service Refer to the tractor operator’s manual to ensure a complete pre-operation inspection and scheduled service is performed according to manufacturer recommendations. The following is a partial list of items requiring inspection: 8.2 Cutter Pre-Operation Inspection/Service Before each cutter use, a complete inspection and service is required to ensure the cutter is in a good and safe working condition.
OPERATION " " OPERATION " Ensure chain guards and rubber deflectors are in position and not damaged. Replace worn, broken, and missing pieces. Check the condition of the retractable rear guard and ensure it raises and lowers properly. Ensure the cylinder operating the retractable door is correctly installed and attached. Inspect the cylinder, hose, fittings, and connection for leaks.
OPERATION " " Ensure the driveline slip clutch shield is in place and in good condition. Ensure the driveline integral shield is in good condition and rotates freely. " Make sure the tractor PTO master shield is in place, lowered, and in good condition. " Inspect the gearbox oil level. A low oil level is a warning sign that the gearbox may be cracked or its seal is damaged and needs replacement. Ensure the gearbox vent is in place on the top of the box and free from clogs.
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.
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 WARNING! Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes.
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.
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.
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. OPERATION DANGER! DANGER! Extreme care should be taken when operating near loose objects such as gravel, rocks, wire, and other debris.
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.
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.
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.
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. OPERATION Large, dense, or wet vegetation may need to be cut in two or more passes to achieve a uniform cut.
OPERATION 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. Do not cut, or drive the tractor into, material that is burning, or areas that recently burnt and may contain hot spots. Burning material, sparks, and coals could be thrown from the cutter to areas of vegetation that might ignite. Tire damage can occur when driving over hot material.
OPERATION 11. DISCONNECTING THE CUTTER FROM THE TRACTOR DANGER! Never stand or allow another person to stand between a running Tractor and the Mower when disconnecting the Implement from the Tractor 3-point hitch. Always shut the Tractor off completely and set the parking brake before attempting to disconnect the Mower pins from the Tractor hitch. Before disconnecting the mower, the PTO must be disengaged and blade rotation at a complete stop.
OPERATION 12. CUTTER STORAGE Properly preparing and storing the cutter 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: It is critical that the driveline clutch slip when an obstacle or heavy load is encountered to avoid cutter and/ or tractor damage.
OPERATION 13. TRANSPORTING THE TRACTOR AND CUTTER Inherent dangers of operating the tractor and cutter and the possibility of accidents are not left behind when you finish cutting an area. Therefore, the operator must employ good judgement and safe operation practices when transporting the tractor and cutter between locations. By using good judgement and following safe tranport procedures, the possibility of accidents while moving between locations can be substantially minimized.
OPERATION 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. 13.
OPERATION OPERATION Make sure that all tractor flashing warning lights, headlights, and brake/taillights are functioning properly before proceeding onto public roads. While newer model tractors have plenty of lighting to provide warning signals as well as artificial operating lighting, most older models where only equipped with operating lights. Consult an authorized tractor dealer for lighting kits and modifications available to upgrade the lighting on older tractor models.
OPERATION 13.2 Hauling the Tractor and Cutter Before transporting a loaded tractor and cutter, 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. Arrange the chains so that when tightened, the chains are pulling downward and against themselves.
