SAFETY Safety Messages A careful operator is the best operator. Safety is of primary importance to the manufacturer and should be to the owner/operator. Most accidents can be avoided by being aware of your equipment, your surroundings, and observing certain precautions. The first section of this manual includes a list of Safety Messages that, if followed, will help protect the operator and bystanders from injury or death.
Page 9
SAFETY Never operate the Tractor or Implement until you have read and completely understand this Manual, the Tractor Operator’s Manual, and each of the Safety Messages found in the Manual or on the Tractor and Implement. Learn how to stop the tractor engine suddenly in an emergency.
Page 10
SAFETY 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.
Page 11
SAFETY PROLONGED EXPOSURE LOUD NOISE CAUSE PERMANENT 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.
Page 12
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.
Page 13
SAFETY 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.
Page 14
SAFETY 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.

GORILLA HEAVY-DUTY TREE CUTTERS OPERATION INSTRUCTIONS Alamo Industrial Gorilla Heavy-Duty Tree Cutters are manufactured with quality material by skilled workers. Gorilla 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.
Page 82
OPERATION 2. OPERATOR REQUIREMENTS Safe operation of the unit is the responsibility of a qualified operator. A qualified operator has read and understands the implement and tractor Operator’s Manuals and is experienced in implement and tractor operation and all associated safety practices. In addition to the safety messages contained in this manual, safety signs are affixed to the implement and tractor.
Page 83
OPERATION 3. TRACTOR REQUIREMENTS The tractor used to operate the mower must have the power capacity to lift, pull, and operate the Power Take Off (PTO) at the mower’s rated speed while traveling at a ground speed between 2 and 5 MPH. Operating the mower with a tractor that does not meet the following requirements may cause tractor or mower damage and be a potential danger to the operator and passersby.
Page 84
OPERATION 3.3 Tractor Horsepower The power required to operate a cutter is determined by the tractor PTO horsepower. For most cutting conditions, the Gorilla requires a tractor with 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.
Page 85
OPERATION 3.6 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.
Page 86
OPERATION 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.

OPERATION 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: •...
Page 88
OPERATION Make sure the tractor is equipped with the correct PTO shaft. Change shafts if needed. Shorten or remove the tractor drawbar to avoid interference when raising and lowering the mower. Board the tractor and start the engine. Position the tractor to the mower with the 3- point lift arms positioned between the respective set of mower A-frame lift lugs.
Page 89
OPERATION 7.1 Setting Mower Height Park the tractor and mower on level ground. 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.
Page 90
OPERATION 7.2 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.
Page 91
OPERATION 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.
Page 92
OPERATION 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. •...

OPERATION 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.
Page 101
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.
Page 102
OPERATION 10.3 Raising the Mower Using the tractor 3-point hitch control lever, raise the mower off the ground about 6”, or just high enough to clear any ground obstacles. When raising the mower, make sure all connection points are securely attached and at least 1” clearance is maintained between the driveline and the deck.
Page 103
OPERATION 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.
Page 104
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.
Page 105
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.
Page 106
OPERATION Rotary Mowers are capable under adverse conditions of throwing objects for great distances (300 feet or more) and causing serious injury or death. Follow safety messages carefully. STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS: -Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable condition;...
Page 107
OPERATION 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 1 and 3 mph. Operate the mower at its full rated PTO speed to maintain blade speed for a clean cut.
Page 108
OPERATION 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. 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.
Page 109
OPERATION Large, dense, or wet vegetation may need to be mowed 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 OPS-R-0043 Then lower the mower to the desired height and mow the vegetation a second time.
Page 110
OPERATION 11.6 Shutting Down the Implement To shut down the cutter, first bring the tractor to a complete stop. Then slow down the cutter by reducing the engine speed before disengaging the PTO. Wait for all rotating motion to stop before proceeding to drive or shut down the tractor.
Page 111
OPERATION 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. To disconnect the mower, first extend the tractor 3- point hitch top link to remove tension on the top link hitch pin.
Page 112
OPERATION 13. MOWER STORAGE Properly preparing and storing the mower at the end of the season is critical to maintaining its appearance and to help ensure years of dependable service. The following are suggested storage procedures: • Thoroughly clean all debris off the mower to prevent damage from rotting grass and standing water.
Page 113
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.
