SAFETY SECTION Safety Section 1-1
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.
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. Never allow inexperienced or untrained personnel to operate the Tractor or Implement without supervision. Make sure the operator has fully read and understood the manuals prior to operation.
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. (SG-11) SAFETY Do not mount or dismount the Tractor while the tractor is moving.
SAFETY PROLONGED EXPOSURE TO LOUD NOISE MAY 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. Noise over 90db adjacent to the Operator over an extended period of time will cause permanent or total hearing loss.
SAFETY 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. (SG-21) Always read carefully and comply fully with the manufacturer’s instructions when handling oil, solvents, cleansers, and any other chemical agent.
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.
SAFETY The rotating parts of this machine have been designed and tested for rugged use. However, the blades could fail upon impact with heavy, solid objects such as metal guard rails and concrete structures. 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.
SAFETY Replace bent or broken blades with new blades. NEVER ATTEMPT TO STRAIGHTEN, WELD, OR WELD HARDFACING ON BLADES SINCE THIS WILL LIKELY CRACK OR OTHERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLY CAUSE SERIOUS INJURY FROM THROWN BLADES. (SGM-10) 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.
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 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.
SAFETY This Implement may be wider than the Tractor. Be careful when operating or transporting this equipment to prevent the Implement from running into or striking sign posts, guard rails, concrete abutments or other solid objects. Such an impact could cause the Implement and Tractor to pivot violently resulting in loss of steering control, serious injury, or even death. Never allow the Implement to contact obstacles.

DRIVING THE TRACTOR AND IMPLEMENT OPERATION Safe tractor transport requires the operator to 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 boom and the tractor operating controls are set for safe transport. To ensure safety while driving the tractor with a boom, review the following. Read all safety instructions.
OPERATION 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.
OPERATION 9.2 Brake and Differential Lock Setting OPERATION Make sure the tractor brakes are in good operating condition. Tractor brakes can be set to operate independently allowing single rear wheel braking action or locked together to provide simultaneous rear wheel braking. FOR MOST DRIVING AND OPERATING CONDITIONS, THE BRAKE PEDALS SHOULD BE LOCKED TOGETHER TO PROVIDE THE MOST EFFECTIVE BRAKING ACTION. Always disengage the tractor differential lock when turning.
OPERATION 9.3 Driving the Tractor and Boom Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the tractor. Never operate the tractor 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.
OPERATION 10. OPERATING THE TRACTOR AND IMPLEMENT OPERATION THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE. The operator must read and understand the Safety and Operation Sections of the implement and tractor operator’s manuals. These manuals must be read and explained to any operator who cannot read. Never allow someone to operate the implement and tractor without complete operating instructions.
OPERATION 10.1 Foreign Debris Hazards/Overhead Obstructions An area to be cut must first be inspected for objects that could be thrown or that could damage the machine. Walk through the area looking for fences, boulders, rocks, culverts, stumps or metal objects. Mark the inspected area with flags. If the area is dense and cannot be walked thoroughly it may be necessary to inspect a smaller area as well as possible, then trim away the part that has been inspected and can safely be removed.
OPERATION Mow at the speed that you can safely operate and control the tractor and mower. The correct mowing speed depends on terrain condition and grass type, density, and height of cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power lines, or when debris and foreign objects are to be avoided. (SGM-07) OPERATION 10.
OPERATION 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. (SGM-08) 10.4 Shutting Down the Implement Park the tractor on a level surface, place the transmission in park or neutral and apply the parking brake.
OPERATION OPERATION BEFORE leaving the tractor seat, always set the parking brake and/or set the tractor transmission in parking gear, disengage the PTO, stop the engine, remove the key, and wait for all moving parts to stop. Place the tractor shift lever into a low range or parking gear to prevent the tractor from rolling. Never dismount a Tractor that is moving or while the engine is running. Operate the Tractor controls from the tractor seat only.
OPERATION Before transporting the tractor between locations, idle the tractor engine, disengage the attached head, and wait for all head motion to come to a complete stop. Place the cutterbar guard over the knife. Remember keep fingers away from the knife so it can move, even with the tractor engine switched off. Place the machine in the transport position by carrying out the following procedure: Position the main arm on the left hand side of the machine. Fully retract the angle arm.
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) OPERATION Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in such a way as to be clearly visible and legible. When transporting the Equipment use the Tractor flashing warning lights and follow all local traffic regulations.
OPERATION When operating on public roads, have consideration for other road users. Pull to the side of the road occasionally to allow all following traffic to pass. Do not exceed the legal speed limit set in your country for agricultural tractors. Always stay alert when transporting the tractor and implement on public roads. Use caution and reduce speed if other vehicles or pedestrians are in the area.
OPERATION 13.2 Hauling the Tractor and Implement OPERATION Before transporting a loaded tractor and implement, measure the height and width dimensions and gross weight of the complete loaded unit. Ensure that the load will be in compliance with the legal limits set for the areas that will be traveled through. OPS-U- 0024 Use adequately sized and rated trailers and equipment to transport the tractor and implement. Consult an authorized dealer to determine the proper equipment required.
OPERATION 14. TROUBLESHOOTING GUIDE HYDRAULIC CYLINDER NOT WORKING -Check level of hydraulic fluid (see sight gauge on tank). Check to see if pump is functioning properly by attempting to use another cylinder or pressure gauge. If pump is working properly, check the pressure on the line. The relief valve may be bypassing fluid at too low pressures. If cylinder is still not functioning properly, check line for stoppage.
MAINTENANCE SECTION Maintenance Section 5-1
MAINTENANCE MAINTENANCE LUBRICATION Refer to the lubrication diagram and grease daily all points indicated. Remember, regular lubrication ensures longer machine life and diminishes service costs. In addition, occasionally oil the con-rod pivots and bushes. FASTENERS Check daily that all bolts and nuts are tight, pins are secure and hydraulic connections are not leaking. PT5 09/10 © 2010 Alamo Group Inc.
MAINTENANCE CUTTERBAR Adjusting the Knife Guides Before commencing any checks or adjustments, lay the cutterbar flat on the ground. Select “CUTTERBAR OFF”, switch off the tractor and disconnect the con rod. MAINTENANCE When adjusted correctly the knife sections (4) lie flush between the fingers and the underside of the knife holder (1) with the fingers projecting 6 MM to 8 MM in front of the knife tips.
MAINTENANCE Sharpening the Knife After five to twenty operating hours, depending on the work involved the knives require re-sharpening. It is recommended that knives are removed from the cutterbar for re-sharpening. Switch off tractor, disconnect the con rod, remove the three setscrews securing the knife heel to the knife and withdraw the knife from the cutterbar. MAINTENANCE Clean the knife and ensure that neither the back nor the knife sections are bent. Straighten as necessary.
MAINTENANCE HYDRAULIC RAMS Ram Seal Replacement- General Information To Change Seals on Angle, Reach and 40 MM Dia Lift Ram 1. Unscrew the gland and withdraw to complete rod assembly. Remove piston locking nut, slide the piston and gland housing off the rod. 2. Lubricate all new seals prior to assembly. 3. Replace the gland seals ensuring they are positioned in the same location from which they were removed. Carefully place the gland housing complete with seals back on the rod. 4.
MAINTENANCE MAINTENANCE Cylinder Rod Maintenance It is important to visually inspect the hydraulic cylinder rods daily before use. It is highly recommended that while the machine is stored or getting very little use that a protectant is applied to the hydraulic cylinder rods to prevent degradation. If the machine receives more frequent use, be sure to fully cycle each cylinder function so that the cylinder rod is coated by the systems hydraulic fluid.
MAINTENANCE Replacing Spool “O” Rings Note: Owing to the sharp edges in the design of the spool, failure to carry out the following procedure could result in damage to the “O” rings resulting in external leakage. Main Relief Valve The main relief valve is pressure set at the factory to 1450 PSI (100 Bar) and is non adjustable. A sticking relief valve will probably cause overheating and/or loss of power. If this is suspected it should be dismantled and examined for dirt and damage.
MAINTENANCE Hose Warranty Warranty is limited to replacement which have failed due to faulty manufacture or materials. Warranty will not be considered on hoses that have suffered damage by abrasion, cuts or being pinched or trapped while in work. MAINTENANCE Neither will a claim be considered where the hose end has been damaged by a flow or where the threads or unions have been damaged by overtightening.
