SAFETY General Safety Instructions and Practices SAFETY 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. Read and understand these Safety Messages before assembling, operating or servicing this Implement. This equipment should only be operated by those persons who have read the manual, who are responsible and trained, and who know how to do so responsibly. The Safety Alert Symbol combined with a Signal Word, as seen below, is used throughout this manual and on decals which are attached to the equipment. The Safety Alert Symbol means: “ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!” The Symbol and Signal Word are intended to warn the owner/operator of impending hazards and the degree of possible injury faced when operating this equipment. Practice all usual and customary safe working precautions and above all---remember safety is up to YOU. Only YOU can prevent serious injury or death from unsafe practices. Indicates an imminently hazardous situation that, if not avoided, WILL result in DEATH OR VERY SERIOUS INJURY. Indicates an imminently hazardous situation that, if not avoided, COULD result in DEATH OR SERIOUS INJURY. Indicates an imminently hazardous situation that, if not avoided, MAY result in MINOR INJURY. Identifies special instructions or procedures that, if not strictly observed, could result in damage to, or destruction of the machine, attachments or the environment. NOTE: Identifies points of particular interest for more efficient and convenient operation or repair.(SG-1) READ, UNDERSTAND, and FOLLOW the following Safety Messages. Serious injury or death may occur unless care is taken to follow the warnings and instructions stated in the Safety Messages. Always use good common sense to avoid hazards. (SG-2) Si no lee ingles, pida ayuda a alguien que si lo lea para que le traduzca las medidas de seguridad. (SG-3) RMB 1660 11/10 © 2010 Alamo Group Inc. Safety Section 1-2 SAFETY Engine Exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the state of California to cause cancer and birth defects or other reproductive harm. (SG-30) Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the state of California to cause cancer, birth defects or other reproductive harm. (SG-31) 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. (SG-4) 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 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) Always read carefully and comply fully with the manufacturer’s instructions when handling oil, solvents, cleansers, and any other chemical agent. (SG-22) RMB 1660 11/10 © 2010 Alamo Group Inc. Safety Section 1-3 SAFETY Operator Safety Instructions and Practices SAFETY 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) 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. 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) Prolonged operation may cause operator boredom and fatigue affecting safe operation. Take scheduled work breaks to help prevent these potentially impaired operating conditions. Never operate the Implement and Tractor in a fatigued or bored mental state which impairs proper and safe operation. (SG-32) Use extreme caution when getting onto the Implement to perform repairs, maintenance and when removing accumulated material. Only stand on solid flat surfaces to ensure good footing. Use a ladder or raised stand to access high spots which cannot be reached from ground level. Slipping and falling can cause serious injury or death. (SG-33) Avoid contact with hot surfaces including hydraulic oil tanks, pumps, motors, valves and hose connections. Relieve hydraulic pressure before performing maintenance or repairs. Use gloves and eye protection when servicing hot components. Contact with a hot surface or fluid can cause serious injury from burns or scalding. (SG-34) DO NOT operate this Implement on a Tractor that is not properly maintained. Should a mechanical or Tractor control failure occur while operating, immediately shut down the Tractor and perform repairs before resuming operation. Serious injury and possible death could occur from not maintaining this Implement and Tractor in good operating condition. (SG-36) Avoid contact with hot surfaces of the engine or muffler. Use gloves and eye protection when servicing hot components. Contact with a hot surface or fluid can cause serious injury from burns or scalding. (SG-38) RMB 1660 11/10 © 2010 Alamo Group Inc. Safety Section 1-4 SAFETY The rotating parts of this machine continue to rotate even after the Tractor 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. (SBM-5) “Wait a minute...Save a life!” 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. (SFL-2) Do not put hands or feet near the cutter bar. Blade contact can result in serious injury. Stay away until all motion has stopped and the mower is securely blocked up. (SSM-1) Do not operate the implement while wearing loose fitting clothing. Entanglement of the clothing with the rotating elements can result in serious injury or even death. Stay clear of all rotating elements at all times. (SSP-03) Connecting & Disconnecting Implement Safety Instructions & Practices Each Rear Wheel must have a minimum of 1500 pound contact with the surface to prevent lateral instability and possible tip-over which could result in serious bodily injury or even death. Widen the wheel tread and add weights if needed. Refer to the mounting instructions or call Customer Service if you need assistance with Counterweight Procedure. (SBM-11) Do Not attempt to raise or lower the boom or mower head unless the Implement is securely attached to the Tractor. The Implement could tip over and cause equipment damage and possible serious injury or death. Do Not use the boom controls to assist in installing the implement on the tractor. Raise or Lower the boom and mower head only while seated in the Tractor operator’s seat with the seat belt securely fastened. Inadvertent contact with the boom controls could allow a component to fall. A sudden or inadvertent fall by any of these components could cause serious injury or even death. (SBM-23) RMB 1660 11/10 © 2010 Alamo Group Inc. Safety Section 1-5 SAFETY 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-09) SAFETY Equipment Operation Safety Instructions and Practices 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 securely in place, or put a secure support under the A-Frame. Lower the implement carefully to the ground. Do not put hands or feet under lifted components. (S3PT-1) 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. (S3PT-12) Use extreme caution when raising the Mower head. Stop the Blades from turning when the Mower Head is raised and passersby are within 300 feet. Raising the Mower head exposes the Cutting Blades which creates a potentially serious hazard and can cause serious injury by objects thrown from the Blades or by contact with the Blades. (SBM-2) Never Leave the mower unattended while the head is in the raised position. The mower could fall causing serious injury to anyone who might inadvertently be under the mower (SBM-4) Always keep a careful lookout and use extreme care when working around overhead obstructions. Never allow the Mower head or boom within 10 feet of any power line. When working close to overhead power lines consult your electric company for a safe code of operation. (SBM-7) The center of Gravity of Tractors equipped with a Rear-Mounted Boom Mower is shifted to the rear and removes weight from the front wheels. Add front ballast until at least 20% of the tractors weight is on the front wheels to prevent rearing up, loss of steering control, and possibly injury. (SBM-10) Use extreme care and Safety Awareness when using the boom mower head to mulch loose brush or wood that has fallen on the ground from overhead trimming. DO NOT mulch this debris if bystanders, vehicles, livestock or buildings are within 300 feet of the mower. This cut debris can be thrown at great velocities and could result in serious injury or even death. (SBM-17) Do not back up this implement when the boom or mower head is extended. Backing could damage the machine or its components. (SBM-19) RMB 1660 11/10 © 2010 Alamo Group Inc. Safety Section 1-6 SAFETY Follow these guidelines to reduce the risk of equipment and grass fires while operating, servicing, and repairing the Mower and Tractor: -Equip the Tractor with a fire extinguisher in an accessible location. -Do Not operate the Mower on a Tractor with an underframe exhaust. -Do Not smoke or have an open flame near the Mower and Tractor. -Do Not attempt to mow or place the mower head close to burning debris. -Never allow clippings or debris to collect near drivelines, gearboxes or hydraulic components such as valves, tanks, pumps and motors. Periodically shut down the Tractor and Mower and clean clippings and collected debris from the mower deck. (SBM-20) Do not operate Mower if excessive vibration exists. Shut down PTO and the Tractor engine. Inspect the Mower to determine the source of the vibration. If Mower blades are missing or damaged replace them immediately. Do not operate the mower until the blades have been replaced and the Mower operates smoothly. Operating the Mower with excessive vibration can result in component failure and 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 Mower to be operated with blades missing. (SFL-4) RMB 1660 11/10 © 2010 Alamo Group Inc. Safety Section 1-7 SAFETY -Do Not drive into burning debris or freshly burnt areas. SAFETY Flail 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 300 FEET UNLESS: -Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable condition; SAFETY -Mower sections exposed Blades; or Wings are running close to and parallel to the ground without -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.) (SFL-6) Operate this Equipment only with a Cab Tractor. Always wear seat belts. BEFORE leaving the tractor seat lower the implement, 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. (SG-9) Never allow children or other persons to ride on the Tractor or Implement. Falling off can result in serious injury or death. (SG-10) 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) RMB 1660 11/10 © 2010 Alamo Group Inc. Safety Section 1-8 (SG-45) SAFETY Do not mount or dismount the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all moving parts are completely stopped. (SG-12) 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) Never run the Tractor engine in a closed building or without adequate ventilation. The exhaust fumes can be hazardous to your health. (SG-23) 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) 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) In case of mechanical difficulty during operation, place the transmission in the park position, set the parking brake, shut down all power, including the PTO and the engine and remove the key. Wait until all rotating motion has stopped before dismounting. (SG-39) RMB 1660 11/10 © 2010 Alamo Group Inc. Safety Section 1-9 SAFETY Do not operate this Equipment with hydraulic oil or fuel leaking. Oil and fuel are explosive and their presence could present a hazard. Do not check for leaks with your hand! High-pressure oil streams from breaks in the line could penetrate the skin and cause tissue damage including gangrene. To check for a hose leak, SHUT the unit ENGINE OFF and remove all hydraulic pressure. Wear oil impenetrable gloves, safety glasses and use Cardboard to check for evidence of oil leaks. If you suspect a leak, REMOVE the HOSE and have it tested at a Dealer. If oil does penetrate the skin, have the injury treated immediately by a physician knowledgeable and skilled in this procedure. (SG-15) SAFETY Do Not operate this equipment in areas where insects such as bees may attack you and/or cause you to lose control of the equipment. If you must enter in such areas, use a tractor with an enclosed Cab and close the windows to prevent insects from entering. If a tractor cab is not available, wear suitable clothing including head, face, and hand protection to shield you from the insects. Attacking insects can cause you to lose control of the tractor, which can result in serious injury or death to you or bystanders. Never dismount a moving tractor. (SG-40) SAFETY 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 300 feet (90 m) 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 these type of items discontinue mowing. (SGM-1) 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 300 feet of mower. (SGM-02) 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. (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-05) 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-06) RMB 1660 11/10 © 2010 Alamo Group Inc. Safety Section 1-10 SAFETY 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) 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 mow with two machines in the same area except with Cab tractors with the windows closed. (SGM-11) Follow these guidelines to reduce the risk of equipment and grass fires while operating, servicing, and repairing the Mower and Tractor: -Equip the Tractor with a fire extinguisher in an accesible location. -Do Not operate the Mower on a Tractor with an underframe exhaust. -Do Not smoke or have an open flame near the Mower and Tractor. -Do Not drive into burning debris or freshly burnt areas. -Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating. -Never allow clippings or debris to collect near drivelines, slip clutches, and gearboxes. Periodically shut down the Tractor and Mower and clean clippings and collected debris from the mower deck. (SGM-12) The Mower is designed for certain mowing applications and is rated to cut up to a specific size vegetation (see Mower Standard Equipment and Specifications). DO NOT use this mower to cut vegetation above the Mower’s rated capacity or to cut any type of nonvegetative material. Only operate this Mower on a properly sized and equipped Tractor. Operating this Mower in an application for which it is not designed and/or operating the Mower with the wrong size Tractor can cause Mower component damage and equipment failure resulting in possible serious injury or death. (SGM-14) Never leave the Implement and Power Unit unattended while the Implement is in the raised position. Accidental operation of a lifting lever or a hydraulic failure may cause the implement to suddenly fall causing serious injury or possible death to anyone who might inadvertently be under the Implement. Lower the implement carefully to the ground. Do not put hands or feet under lifted components. (SPU-3) RMB 1660 11/10 © 2010 Alamo Group Inc. Safety Section 1-11 SAFETY (SGM-08) SAFETY Do not let the Blades turn when the Mower Deck is raised for any reason, including clearance or for turning.

(SGM-13) PARTS INFORMATION Bush Hog mowers use balanced and matched system components for blade carriers, blades, cuttershafts, knives, knife hangers, rollers, drivetrain components, and bearings. These parts are made and tested to Bush Hog specifications. Non-genuine "will fit" parts do not consistently meet these specifications. The use of “will fit” parts may reduce mower performance, void warranties, and present a safety hazard. Use genuine Bush Hog mower parts for economy and safety. (SPBH-1) SEE YOUR BUSH HOG DEALER Transporting Safety Instructions and Practices 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-02) Allow sufficient clearance for the Implement to swing outward while turning. Implements carried behind the Tractor will swing outside the tire path when making turns. Contacting a solid object while turning will cause equipment damage and possible injury. (S3PT-20) Be particularly careful in transport. The Mower has raised the center of gravity for the tractor and has increased the possibility of overturn. Turn curves or go up slopes only at low speed and using a gradual turning angle. Slow down on rough or uneven surfaces. (SBM-3) RMB 1660 11/10 © 2010 Alamo Group Inc. Safety Section 1-14 SAFETY When transporting Boom Mower on a truck or trailer, the height or width may exceed legal limits when the boom is in the transport position. Contact with side or overhead structures or power lines can cause property damage or serious injury or death. If necessary lower boom to reduce height and/or remove mowing head to reduce width to the legal limits. (SBM-8) Make sure the Rotor Control Lever is in the OFF position and control lever locking mechanism is in the “Locked” Position to prevent accidental movement. (SBM-26) Secure the boom and mower head in the transport position before traveling on public roads. Never transport on public roads with the boom and mower head extended. Always disengage and lock out the hydraulic controls for the boom mower before transporting. Inadvertent boom movement on public roads may contact with other vehicles resulting in serious bodily injuries or even death. (SBM-21) 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. (SG-6) RMB 1660 11/10 © 2010 Alamo Group Inc. Safety Section 1-15 SAFETY Never operate the Tractor and Mower Unit without an OPS (Operators Protective Structure) or Cab to prevent injury from objects thrown from ground or from overhead trimming. Stop mowing if workers or passersby are within 300 feet. (SBM-9) SAFETY 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. SAFETY Before transporting the Tractor and Implement, determine the proper 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 transport speed not to exceed 20 mph (30 kph) for transporting this equipment. Test the equipment at a slow speed in turns. Increase the speed through the turn only after you determine that the equipment can be operated 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 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 reduce your speed. Be aware of traffic around you and watch out for the other guy. (SG-19) Your driving vision may be reduced or impaired by the tractor, cab, or implement. Before driving on public roadways identify any limited vision areas, and make adjustments to your operating position, mirrors, and the implement transport position so that you can clearly see the area where you will be traveling, and any traffic that may approach you. Failure to maintain adequate vision of the public roadway and traffic can result in serious injury or even death. (STI-10) Concluding Safety Instructions and Practices In addition to the design and configuration of this Implement, including Safety Signs and Safety Equipment, hazard control and accident prevention are dependent upon the awareness, concern, prudence, and proper training of personnel involved in the operation, transport, maintenance, and storage of the machine.

Introduction Section 2-2 INTRODUCTION INTRODUCTION The Bush Hog Boom Mower is primarily designed for grass cutting and trimming hedges. This mower is assembled for operation with 540 RPM tractor input only. With proper use and maintenance the mower should provide years of dependable service. For Non-Agricultural use, OSHA, ASABE, SAE and ANSI standards require the use of Chain Guards, Deflectors, or Solid Skirts at all times. The Mower manufacturer strongly recommends the use of Chain Guards, Deflectors, 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. At least 20% of the tractor’s total weight must be on the front tires with the Mower lifted to provide adequate traction for safe steering under good conditions. Slow down on hills, rough terrain, and curves. Mower Orientation: Front and rear, and left and right are determined by the normal direction of travel (the same as on your automobile). RMB 1660 11/10 © 2010 Alamo Group Inc. Introduction Section 2-3 INTRODUCTION ATTENTION OWNER/ OPERATOR BEFORE OPERATING THIS MACHINE: 1. Carefully read the Operator’s Manual, completely understand the Safety Messages and instructions, and know how to operate correctly both the Mower and Power Unit. INTRODUCTION 2. Fill out the Warranty Card in full. Be sure to answer all questions, including the Serial Number of the Mower. Mail promptly using the return envelope included with the Operator’s Manual. NOTE: Warranties are honored only if completed “Owner Registration and Warranty” forms are received by Alamo Group within thirty days of delivery of the mower. 3. Record the Mower Model and Serial Numbers on the Warranty page at the end of the Operator’s Manual. Keep this as part of the permanent maintenance file for the Mower. RMB 1660 11/10 © 2010 Alamo Group Inc. Introduction Section 2-4 ASSEMBLY SECTION Assembly Section 3-1 © 2010 Alamo Group Inc. ASSEMBLY TRACTOR SELECTION MINIMUM TRACTOR WEIGHTS - including ballast weight if necessary: All models – 6,600 lbs. ASSEMBLY MINIMUM HP REQUIREMENTS: All models – 60 PTO HP LINKAGE: Category 2 P.T.O. SHAFT: Tractor must be equipped with a live drive PTO to enable forward motion to be stopped while the flail head continues to operate. CHECK CHAINS/STABILIZERS: Check chains or stabilizers must be fitted and tightened. TRACTOR OPERATOR STATION: Bush Hog recommends installing the 1660 Boom Mower on fully enclosed cab tractors equipped with impact resistant glass windows. Do Not Operate if Tractor Cab is damaged. RMB 1660 11/10 © 2010 Alamo Group Inc. Assembly Section 3-2 ASSEMBLY TRACTOR PREPARATION Fitting Operator Guard Use tractor with safety glass windows if possible and fit Operator guard using the hooks provided. Shape mesh to cover all vulnerable areas. Remember the driver must be looking through mesh and/or poly carbonate glazing when viewing the flail head in any working position - unless the tractor/cab manufacturer can demonstrate that the penetration resistance is equivalent to, or higher than, that provided by mesh/poly carbonate glazing. ASSEMBLY Wheel Width: Set wheel widths as wide as possible. Lift Links: Adjust lift links until they are equal length. Tractor Ballast: It is imperative when attaching ‘third-party’ equipment to a tractor that the maximum possible stability of the machine and tractor combination is achieved – this can be accomplished by the utilization of ‘ballast’ in order to counter-balance the additional equipment added. Front weights may be required to place 20% of total outfit weight on the front axle for stable transport on the road and to reduce ‘crabbing’ due to the drag of the cutting unit when working on the ground. Rear weights may be required to maintain a reasonable amount of rear axle load on the opposite wheel from the arms when in work; for normal off-ground work i.e. hedge cutting this should be 20% of rear axle weight or more for adequate control, and for ground work i.e. grass mowing with experienced operators, this can be reduced to 10%. All factors must be addressed in order to match the type and nature of the equipment added to the circumstances under which it will be used. The center of gravity on a RMB 1660 will constantly change as the boom or cutting attachment moves. Maintaining proper balance during operation and transport is critical. Factors that affect stability: • Center of gravity of the tractor/machine combination. • Geometric conditions, e.g. position of the cutting head and ballast. • Weight, track width and wheelbase of the tractor. • Acceleration, braking, turning and the relative position of the cutting head during these • operations. • Ground conditions, e.g. slope, grip, load capability of the soil/surface. • Rigidity of implement mounting. RMB 1660 11/10 © 2010 Alamo Group Inc. Assembly Section 3-3 ASSEMBLY ASSEMBLY Suggestions to increase stability: • Increasing rear wheel track; a tractor with a wider wheel track is more stable. • Ballasting the wheel; it is preferable to use external weights but liquid can be added to around 75% of the tire volume – water with anti-freeze or the heavier Calcium Chloride alternative can be used. • Addition of weights – care should be taken in selecting the location of the weights to ensure they are added to a position that offers the greatest advantage. • Front axle locking; a cylinder can be used to ‘lock’ the front axle in work only – locking the axle moves the ‘balance line’ and can be used to transfer weight to the front axle from the rear (check with tractor manufacturer). The advice above is offered as a guide for stability only and is not a guide to tractor strength - it is therefore recommended that you consult your tractor manufacturer or local dealer to obtain specific advise on this subject, additionally advice should be sought from a tire specialist with regard to tire pressures and ratings suitable for the type and nature of the machine you intend to fit. DEALER SETUP INSTRUCTIONS 1. The machine will be delivered in a partially dismantled condition, secured with transport strap and banding. 2. Choose a firm level site. 3. Remove the transport strap, banding straps and loose items. 4. Check the oil level. 5. Raise the machine using overhead lifting equipment with a minimum capacity of 3307 lbs. LEAVE IN POSITION AT THIS STAGE. 6. Lower the legs and pin in position selecting the holes that position the machines gearbox stub shaft approx. 3” below the tractors P.T.O. shaft. NOTE: Leg pin position used. 7. Unbolt stabilizer from machine and remove the stabilizer nose quadrant pin. RMB 1660 11/10 © 2010 Alamo Group Inc. Assembly Section 3-4 ASSEMBLY ATTACHMENT TO TRACTOR Reverse tractor squarely up to the machine. • Connect the tractors sway bars - selecting the rear most hole in the machines lower link brackets that allow the machine to be mounted without contacting the tractor. • Ensure that the same hole is used on both sides. • If necessary fit the spacers supplied (as required) to minimise sideways movement of the tractor sway bars within the hitch brackets. • Tighten tractor’s stabilizers. • The lifting equipment may now be removed. • Fit the stabilizer tongue (A or B) into the tractors top link position. Use the highest position available avoiding any load sensing properties. • The bolt-on tongue of the stabilizer is reversible to accommodate a variety of tractor linkage designs. • Stretch out the stabilizer and rest the bottom legs on the lower rail. • Do not fit stabilizer lower pins at this stage. RMB 1660 11/10 © 2010 Alamo Group Inc. Assembly Section 3-5 ASSEMBLY • ASSEMBLY Fit the machine to top link • Raise machine on tractor linkage until the tractors PTO and the machines gearbox stub shaft are approximately in line. ASSEMBLY • NOTE: As lift occurs be aware the machine may tilt slightly. The four levers of machine controls must be operated from the tractor seat. During this operation ensure no one is standing on or among the linkage arms or bars. Set tractor hydraulics to position control. Never allow anyone below the frame unless it is securely blocked up. RMB 1660 11/10 © 2010 Alamo Group Inc. Assembly Section 3-6 ASSEMBLY • Replace the stabilizer quadrant pin and secure with the clip pin. NOTE: The quadrant pin must be fitted in the lowest hole on the stabilizer in order that it acts as a “Bottom Stop”. This will prevent the machine from dropping when stopped and permit the tractor’s in-built transport protection system to function correctly during operation and transportation. Ensure the tractor’s linkage is in “Position Control” and the linkage raised sufficiently to hold the sickle bar at the correct height and remove the load from the quadrant pin NOTE: Never fit the quadrant pin in a location hole that locks the stabilizer as this can cause damage to the machine and/or tractor. • Adjust the top link to bring the machine frame into the vertical position. RMB 1660 11/10 © 2010 Alamo Group Inc. Assembly Section 3-7 ASSEMBLY • ASSEMBLY ASSEMBLY Check that the welded in pins between the stabilizers jaws are in contact with the mounting rail. If not the machine must be lowered to the ground and the next higher hole on the stabilizer valve selected, the machine raised and contact checked. Repeat again in the third hole if necessary. On subsequent fitting to the same tractor the hole selected is always used. • Adjust the top link to bring the frame of the machine into the vertical position. RMB 1660 11/10 © 2010 Alamo Group Inc. Assembly Section 3-8 ASSEMBLY Adjust using the mounting hole that allows the P.T.O. and gearbox shaft to align as near as possible. • Fit positioning stops - these remain in position until tractor is changed • Lower tractor linkage control so that the machine weight is taken by the yoke. RMB 1660 11/10 © 2010 Alamo Group Inc. Assembly Section 3-9 ASSEMBLY • ASSEMBLY Raise the stand legs into the work position and secure with lock pins. • Tighten check chains and/or stabilizer bars. • Fit machine controls into the cab. • Measure P.T.O. and cut to dimension shown. ASSEMBLY • Note: For subsequent use on different tractors measure again - there must be a minimum shaft overlap of 6”. RMB 1660 11/10 © 2010 Alamo Group Inc. Assembly Section 3-10 ASSEMBLY Fit PTO shaft in position. • Attach safety chains (A) on driveline to a convenient location to prevent rotation of the shaft guarding. • Ensure the Lift Cylinder shut-off valve and Slew Cylinder shut-off valve are open. • Operate the lift up controls and raise the dipper arm end just enough to clear the ground. • Pivot out the dipper arm until the tension link can be connected. ASSEMBLY • Do Not attempt to raise or lower the boom or mower head unless the Implement is securely attached to the Tractor. The Implement could tip over and cause equipment damage and possible serious injury or death. Do Not use the boom controls to assist in installing the implement on the tractor. Raise or Lower the boom and mower head only while seated in the Tractor operator’s seat with the seat belt securely fastened. Inadvertent contact with the boom controls could allow a component to fall. A sudden or inadvertent fall by any of these components could cause serious injury or even death. (SBM-23) RMB 1660 11/10 © 2010 Alamo Group Inc. Assembly Section 3-11 ASSEMBLY Flail Head Attachment ASSEMBLY Operate machine controls to maneuver boom arm into flailhead attachment.

Operation Section 4-7 OPERATION 3.6 Tractor Horsepower OPERATION 3.9 Front End Weight A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the 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. OPS-U- 0005 OPERATION 3.10 Power Take Off (PTO) Depending on the unit, the mower is designed to operate at a PTO speed of 540 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. Those operating at 540 RPM will have a 6-spline shaft and those operating at 1000 RPM will have a 21-spline shaft. Note: Refer to the tractor owner’s manual for instructions to change 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_B 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 Implement resulting in excessive vibration, thrown objects, and blade and implement 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) 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.

BREAKAWAY The machine is fitted with a hydraulic breakaway device which protects the structure of the machine should an unforeseen obstacle be encountered. OPERATION NOTE: The breakaway function does not relieve the operator of his responsibility to drive carefully, be alert and AVOID OBVIOUS HAZARDS BEFORE CONTACT OCCURS. Breakaway may occur momentarily during normal work should an extra thick or dense patch of vegetation be encountered. In these instances tractor forward motion may be maintained with care. Where breakaway has occurred as a result of contacting a post or tree etc. the tractor must be halted and the controls of the machine utilized to maneuver the head away from the obstacle. NEVER CONTINUE FORWARD MOTION TO DRAG THE HEAD AROUND THE OBSTACLE IN BREAKBACK POSITION. NOTE: The force required to activate the breakaway system will vary dependent upon the gradient of work. It will require less force when working uphill and vice versa. With 'SLEW' selected When the slew relief valve setting is exceeded oil is displaced from the slew cylinder allowing the arm to pivot backwards horizontally and the obstacle to be cleared. Re-setting the head into the working position is done automatically by selecting 'SLEW OUT' on the control assembly. Powered Slew The slew feature allows a 95° arc of powered arm movement on the working side from right angles to the tractor to 5º beyond the direct line back. The feature is required to place the machine in the transport position but can also be used to swing the arm back and forth while cutting awkward areas and corners to avoiding the need to constantly reposition the tractor. To operate in this way, 'SLEW' must be selected on the control assembly. If breakaway occurs the slew motion must be reversed to allow the slew breakaway relief valve to reset and the ram to become operable again. Extra care must be taken when working in 'SLEW’ mode with the reach fully in – IT IS POSSIBLE FOR THE FLAILHEAD TO HIT THE TRACTOR OR MACHINE FRAME. RMB 1660 11/10 © 2010 Alamo Group Inc. Operation Section 4-22 OPERATION 9. ROTOR OPERATING SPEED Ensure that the rotor control lever is in the ‘STOP’ position before engaging the PTO shaft. Allow the oil to circulate for a minute or so before operating the armhead levers. Position the flail head in a safe position, increase the engine speed to a high idle and move rotor control lever to ‘START’. After initial surging the rotor will run at even speed. 10. FORWARD SPEED OPERATION The material being cut determines tractor forward speed. Forward speed can be as fast as that which allows the flail head sufficient time to cut the vegetation properly. Too fast a speed will be indicated by over frequent operation of the breakaway system, a fall off in tractor engine revs and a poor finish to the work leaving ragged uncut tufts and poorly mulched cuttings. 11. HIGH VOLTAGE CABLES Depending on the voltage of the cables and the weather conditions there is a danger of electric flashover if the head or arms approach the cables too closely. ALWAYS MAINTAIN A MINIMUM CLEARANCE DISTANCE OF 10 FEET WHEN OPERATING NEAR HIGH VOLTAGE CABLES. If in any doubt consult your local electric company regarding a safe procedure for work. OVERHEAD OBSTRUCTIONS Always be aware that the machine is approximately 13 ft. high when folded - take care when maneuvering in areas with overhead obstacles especially power cables, low bridges etc. or when entering buildings. RMB 1660 11/10 © 2010 Alamo Group Inc. Operation Section 4-23 OPERATION 12. Hedge Cutting Procedure OPERATION Cut the side and bottom of the field side first. This leaves the maximum thickness of hedge on the road side to prevent the possibility of any debris being thrown through the hedge into the path of oncoming vehicles. Cut the side and bottom of the road side. Top cut the hedge to the height required. NOTE: Never cut over the far side of the hedge. It is impossible to see any potential hazards and the position of the flail head will allow the possibility of debris being thrown through the hedge towards the tractor and operator. RMB 1660 11/10 © 2010 Alamo Group Inc. Operation Section 4-24 OPERATION 12.1 Working on Adverse Slopes When working high with the reach fully extended, it is possible for the main arm balance to go ‘OverCenter’ and take the weight off the lift cylinder. A restrictor in the gland connection of the lift ram prevents sudden unpredictable movements should this occur. 13. Lift Float Kit (Optional) Fitting Location The hydraulic float kit should be mounted to the special bracket in such a position that it does not foul any other component during the slewing motion. RMB 1660 11/10 © 2010 Alamo Group Inc. Operation Section 4-25 OPERATION NOTE: Always inspect the work area prior to cutting to remove hazardous material and note any immovable objects. OPERATION 14. 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. Decals on the Boom warn you of particular and multiple hazards. Some decals are attached close to part of the Boom where there is a possible hazard. Read and make sure you understand the safety messages before you operate the implement. Keep all decals clean and readable. Replace lost or damaged decals, refer to safety section for more information. Power for operating the mower is supplied from the tractor PTO. Refer to your tractor manual instructions for engaging and disengaging the PTO. Start the tractor and bring the engine speed up to normal operating 540 PTO speed. Always engage the PTO at low engine RPM and run the mower for a short period until all air is removed from the hoses. Keep all person's well clear of mower since blades can throw objects with great velocity for a considerable distance! KEEP CLEAR! OPS-B- 0005 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. (SG-4) Always maintain the safety signs in good readable condition. If the safety signs are missing, damaged, or unreadable, obtain and install replacement safety signs immediately. (SG-5) 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. (S3PT-12) BEFORE leaving the tractor seat lower the implement, 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. (SG-9) RMB 1660 11/10 © 2010 Alamo Group Inc. Operation Section 4-26 OPERATION 14.1 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. OPS-U-0033 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. 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. OPSU- 0013 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. RMB 1660 11/10 © 2010 Alamo Group Inc. Operation Section 4-27 OPERATION 14.2 Brake and Differential Lock Setting OPERATION 14.3 Driving the Tractor and Boom OPERATION 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. Perform turns with the tractor and mower at slow speeds to determine how the tractor with an attached implement handles a turn. Determine the safe speed to maintain proper control of the tractor when making turns. When turning with the implement the overall working length and width of the unit is increased. Allow additional clearance for the unit when turning or when passing large obstructions. 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. 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. OPS-B- 0006_G Never Leave the mower unattended while the head is in the raised position. The mower could fall causing serious injury to anyone who might inadvertently be under the mower (SBM-4) Always keep a careful lookout and use extreme care when working around overhead obstructions. Never allow the Mower head or boom within 10 feet of any power line. When working close to overhead power lines consult your electric company for a safe code of operation. (SBM-7) 15. OPERATING THE TRACTOR AND IMPLEMENT 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. Before starting any operation, the operator must become familiar with the area to be worked in 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. OPS-U- 0015 RMB 1660 11/10 © 2010 Alamo Group Inc. Operation Section 4-28 OPERATION 15.1 Foreign Debris Hazards Before mowing, inspect the area to make sure there are no foreign objects that the mower 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 mower blades from contacting them. Always wear your seat belt securely fastened and only operate the tractor and mower with the ROPS in the raised position. If the tractor or mower hits a tree stump, rock, or bump, a sudden movement could throw you off of the seat and under the tractor and/or mower. 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. OPS-F-0010 15.2 Bystanders/Passersby Precautions If a bystander comes within 300 feet of the tractor while the mower 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 300 foot distance. OPS-R-0024 RMB 1660 11/10 © 2010 Alamo Group Inc. Operation Section 4-29 OPERATION If you hit a solid object or foreign debris, stop the mower and tractor at once. Immediately idle the engine speed and disengage the PTO. Wait for all mower rotating motion to stop, then raise the mower 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 mower and make any needed repairs immediately. Make sure the blades are not damaged and the carrier is balanced before resuming operation. OPERATION Flail 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 300 FEET UNLESS: -Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable condition; OPERATION -Mower sections exposed Blades; or Wings are running close to and parallel to the ground without -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.) (SFL-6) 15.3 Engaging the Power Take Off (PTO) Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement must be completely lowered and the deck positioned at a safe operating height. NEVER engage the PTO with the implement in the raised position. 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 the rated speed. If you hear unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the implement to determine the cause of the noise or vibration and repair the abnormality. OPS-U- 0027 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-09) RMB 1660 11/10 © 2010 Alamo Group Inc. Operation Section 4-30 OPERATION 15.4 Operating Speed and Ground Speed Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Do Not exceed 2 MPH while operating. Operate the mower at its full rated PTO speed to maintain blade speed for a clean cut. Refer to the tractor operator’s manual or the tractor instrument panel for the engine speed and gear to provide the required operating and desired ground speed. Make sure that the mower is operating at its full rated speed before entering the vegetation to be cut. Always start and stop cutting blades with engine near idle. 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) 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) 15.5 Operating the Mower The mower is designed to cut vegetation up to 1-1/2” in diameter. Sharp blades will produce a cleaner cut and require less power. Travel at a speed that allows the mower sufficient time to cut through the vegetation and maintain the PTO operating speed to prevent overloading the mower and tractor. Choose a driving pattern that provides the maximum pass length and minimizes turning. Under certain conditions, tractor tires may roll some grasses down preventing them from being cut at the same height as the surrounding area. When this occurs, reduce the tractor ground speed while maintaining the operating speed of the mower. A slower ground speed will permit grasses to at least partially rebound and be cut. Taking a partial cut and/or reversing the direction of travel may also help produce a cleaner cut. Avoid mowing in the reverse direction when possible. In situations where the mower must be backed to access areas to be cut, make sure there are no persons or other foreign debris behind the mower before mowing in reverse. When mowing in reverse, operate the tractor and mower at a reduced ground speed to ensure tractor and mower control is maintained. OPS-R-0026_N RMB 1660 11/10 © 2010 Alamo Group Inc. Operation Section 4-31 OPERATION 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 implement 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. OPS-B- 0009 OPERATION OPERATION 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 300 feet of mower. (SGM-02) Do not mow with two machines in the same area except with Cab tractors with the windows closed. (SGM-11) 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 300 feet (90 m) 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 these type of items discontinue mowing. (SGM-1) 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) Follow these guidelines to reduce the risk of equipment and grass fires while operating, servicing, and repairing the Mower and Tractor: -Equip the Tractor with a fire extinguisher in an accesible location. -Do Not operate the Mower on a Tractor with an underframe exhaust. -Do Not smoke or have an open flame near the Mower and Tractor. -Do Not drive into burning debris or freshly burnt areas. -Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating. -Never allow clippings or debris to collect near drivelines, slip clutches, and gearboxes. Periodically shut down the Tractor and Mower and clean clippings and collected debris from the mower deck. (SGM-12) RMB 1660 11/10 © 2010 Alamo Group Inc.

Grass Flail • • • • The Grass Flail head is rated for cutting grass and small brush up to 1-1/2”. The Grass Flail operates attached to the boom arm, and is ideal for cutting hard to reach areas where a smooth cut is required. Cutting height ranges from 3/4” to 4” in vegetation. Cutting height is set by adjusting the height of the roller assembly. When operating near the ground or when mulching be particularly careful that there are no bystanders or animals with a 300 feet. Debris tends to fly out at great speed and can injure or even cause death. OPS-B- 0040_B Sickle Bar • • • • • The Sickle Bar Cutter will cut a 5’ swath through tough weeds and grass. The Sickle Bar Cutter is operated attached to the boom arm and is ideal for vegetation maintenance When operating the Sickle Bar correctly it will give you a fast, efficient, and cost-effective method of vegetation maintenance. The Sickle Bar will also cut vegetation through tough weeds under water, ideal for maintaining ponds, creeks, and other areas that may be under shallow water. When operating the unit be sure there are no bystanders or animals within 300 feet of the unit. OPS-B- 0049 RMB 1660 11/10 © 2010 Alamo Group Inc.

TRANSPORT POSITION-Head Attached The machine is transported in line to the rear of the tractor with a minimum of 11-1/4” clearance between the tension link and the rear cross member of the tractor cab. OPERATION 19. TRANSPORT POSITION-Head Removal With the flail head removed the arms are fully folded but the lift ram remains retracted. If the lift ram is extended the weight of the arms will cause the balance of the machine to go over center causing the tension link to crash into the rear cross member of the tractors cab. During transport the 'SLEW’ mode must ALWAYS be selected on the control assembly. RMB 1660 11/10 © 2010 Alamo Group Inc. Operation Section 4-37 OPERATION 19.1 Transport Height OPERATION There is no fixed dimension for transport height. It will vary depending on the height that the machine is carried and the degree of arm fold that the rear of the cab will allow. For the majority of installations the transport height will generally fall between a minimum of 3.45m (11’1/2”) and a maximum of 3.65m (12’) when the machine is correctly folded. 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. Never tow the implement at speeds greater than 20 MPH (32 kph). OPS-U- 0018 19.2 Transporting on Public Roadways Extreme caution should be used when transporting the tractor and implement on public roadways. The tractor must be equipped with all required safety warning features including a SMV emblem and flashing warning lights to alert drivers of the tractor’s presence. Remember that roadways are primarily designed for automotive drivers and most drivers will not be looking out for you, therefore, you must look out for them. Check your side view mirrors frequently and remember that vehicles will approach quickly because of the tractor’s slower speed. Be extremely cautious when the piece of equipment that you are towing is wider than the tractor tire width and/or extends beyond your lane of the road. Make sure that a proper size safety tow chain is secured between the tractor and implement before entering a public road. OPS-U- 0019 NOTE: Ensure that the mower sections are fully raised and that the transport locks are engaged for each section. RMB 1660 11/10 © 2010 Alamo Group Inc. Operation Section 4-38 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) 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. (SG-6) 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 and 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. OPS-B-0015 RMB 1660 11/10 © 2010 Alamo Group Inc. Operation Section 4-39 OPERATION The SMV (Slow-Moving Vehicle) emblem is universal symbol used to alert drivers of the presence of equipment traveling on roadways at a slow speed. SMV signs are a triangular bright orange with reflective red trim for both easy day and night visibility. Make sure the SMV sign is clean and visible from the rear of the unit before transporting the tractor and implement on a public roadway. Replace the SMV emblem if faded, damaged, or no longer reflective. OPS-U- 0020 OPERATION 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 state or municipality for agricultural tractors. Always stay alert when transporting the tractor and mower on public roads. Especially in busy cities, the boom extends to right farther then the tractors width, so be careful there are no bystanders, poles, large obstructions or any vehicles that may be in path of the mower head or boom. Use caution and reduce speed if other vehicles or pedestrians are in the area. OPS-B- 0016 Reduce speed before turning or applying the brakes. Ensure that both brake pedals are locked together when operating on public roads. OPS-U- 0023 When transporting Boom Mower on a truck or trailer, the height or width may exceed legal limits when the boom is in the transport position. Contact with side or overhead structures or power lines can cause property damage or serious injury or death. If necessary lower boom to reduce height and/or remove mowing head to reduce width to the legal limits. (SBM-8) RMB 1660 11/10 © 2010 Alamo Group Inc. Operation Section 4-40 OPERATION 19.3 Hauling the Tractor and Implement 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 Arrange the chains so that when tightened, the chains are pulling downward and against themselves. Carefully tighten the securing chains or other fasteners using boomers or binders to apply maximum tension. Use extreme care when attaching and removing the securing devices as the extreme tension involved when released has the potential to inflict serious injury. While hauling the tractor and implement, make occasional stops to check that the tractor and implement have not moved or shifted and that the securing chains have maintained tension. If during transport a hard braking, sharp turning, or swerving action was performed, stop at the next safe location to inspect the security of the load.

MAINTENANCE MAINTENANCE LUBRICATION General Grease all locations shown daily. PTO SHAFT INSPECTION Regularly check the PTO guards for damage and ensure the anti rotation chains are in place and that their anchor points are in good condition. Do not operate the machine with any damaged guards - replace suspect items immediately. PTO SHAFT LUBRICATION Lubricate all the points indicated in the diagram below at the intervals stated using a general purpose lithium based grease. RMB 1660 11/10 © 2010 Alamo Group Inc. Maintenance Section 5-2 MAINTENANCE HYDRAULIC SYSTEM Oil Supply Check daily the oil level in the reservoir. No fixed time period can be quoted for oil changes as operating conditions and maintenance standards vary so widely. Burnt and scorched oil odors and the oil darkening and thickening are all signs of oxidation and indicate the oil should be changed. Contamination can be reduced by: 1. 2. 3. Cleaning off around the reservoir cap before removal, and keeping that area clean. Using clean containers when replenishing the system. Regular servicing of the filtration system. Filtration Maintenance A 125-micron suction strainer and a low-pressure 10-micron full flow return line filter protect the machine. Suction strainer The strainer is permanently fixed within the reservoir. Should symptoms of pump cavitation or spongy intermittent operation occur the tank must be drained and flushed out with a suitable cleaning agent e.g. clean diesel oil. Return Line Filter The elements should be changed after the first 50 hours and thereafter at 500-hour intervals. It is important to note hours worked as if the filter becomes blocked an internal by-pass within the canister will operate and no symptoms of filter malfunction will occur to jog your memory. HYDRAULIC HOSES The condition of all hoses should be carefully checked during routine service of the machine. Hoses that have been chafed or damaged on their outer casing should be securely wrapped with waterproof adhesive tape to stop the metal braid from rusting. Hoses that have been suffered damage to the metal braid should be changed at the earliest opportunity. RMB 1660 11/10 © 2010 Alamo Group Inc. Maintenance Section 5-3 MAINTENANCE Moisture which results from condensation can become entrapped in the oil and cannot be removed by filtration so that contamination is a progressive factor. MAINTENANCE Hose Replacement MAINTENANCE 1. Replace one hose at a time to avoid the risk of wrong connections. 2. When the hose is screwed to an additional fitting or union, use a second spanner on the union to avoid breaking both seals. 3. Do not use jointing compound on the threads. 4. Avoid twisting the hose. Adjust the hose line to ensure freedom from rubbing or trapping before tightening hose end connections. Before changing hoses, study the installation. These are carefully calculated to prevent hose damage during operation. Always replace hoses in exactly the same manner. This is especially important for the flail hoses where they must be crossed, upper to lower, at the dipper and head pivots. Hose Warranty Warranty is limited to replacement of hoses which have failed due to faulty materials of manufacture. Warranty will not be considered on hoses that have suffered damage by abrasion, cuts or being pinched or trapped while in work. Neither will a claim be considered where a hose end has been damaged by a blow or where the threads or unions have been damaged by overtightening. Soft Seal hose connections are capable of holding pressure when the nut is only ‘finger tight’. It is therefore recommended that when dismantling, the hose be manually flexed to relieve any residual pressure with the retaining nut slackened prior to complete disassembly. RMB 1660 11/10 © 2010 Alamo Group Inc. Maintenance Section 5-4 MAINTENANCE FLAILHEAD 1. Frequently inspect the rotor assembly for damaged or missing flails. Bolts and nuts securing the flails to the rotor should be regularly checked and kept tight. The correct torque setting for these locknuts is 135 Nm (100 lbs/ft.). Use only the correct flail bolt and locking nut. Check the flail pivot bushes for possible damage or wear. They do not require oil. 3. Blunt flails absorb a lot of power and leave an untidy finish to work. They should be sharpened on a grindstone or with a portable grinder periodically. Blades MUST BE sharpened in pairs. 4. Wear protective gear when sharpening flails. 5. Ensure that the bearing housings and hydraulic mounting nuts and bolts are kept tight. They should be checked during servicing. CABLES The cables operate on a push/pull system with the spool centering springs always returning the spool to the neutral position when the handle is released. Care should be taken during installation and operation to ensure that the cables are not trapped or kinked. Any abrasion or damage to the outer casing should be sealed with plastic insulation tape to avoid moisture penetrating. No routine adjustment of the cables are necessary as they do not stretch. The threaded collar is correctly adjusted when the lever is in a vertical position in its housing allowing an equal amount of travel in either direction. On no account should any attempt be made to lubricate the cables which are assembled with a special lubricant during manufacture. NOTE: Be careful in determining the correct cable connections on both the control unit and the valve in the event of cable replacement. RMB 1660 11/10 © 2010 Alamo Group Inc. Maintenance Section 5-5 MAINTENANCE 2. Do not attempt to run the rotor with flails missing. Imbalance will cause severe vibration and can rapidly damage the rotor shaft bearings. As an emergency measure, if a flail is broken off or lost, remove another on the opposite site of the rotor to retain balance. Always replace flails in opposite pairs and never match up a new flail with a resharpened one which will of course be lighter. MAINTENANCE PTO GEARBOX Refill the gearbox after the first initial 50 hours and thereafter yearly or 500 hour intervals. or whichever comes first. MAINTENANCE Drainage of the gearbox for an oil change is via the drain plug located on the base of the gearbox. To refill or for ‘topping up’ remove both plugs indicated below and fill gearbox via the filler plug to a point where the oil starts to run from the level plug orifice – replace plugs and tighten securely. Fill with multipurpose gearbox oil P/ N 00786250. STORAGE If machine is to be left standing for an extended period of time, lightly coat the exposed portions of the ram rods with grease. Subsequently, this grease which becomes contaminated with dust and grit should be wiped off before the rams are next moved. If the machine has to be stored outside, tie a piece of tarpaulin or canvas over the control assembly. Do not use a plastic fertilizer bag which could lead to rapid corrosion. RMB 1660 11/10 © 2010 Alamo Group Inc. Maintenance Section 5-6 MAINTENANCE PROPER TORQUE VALUES FOR FASTENERS The chart lists the correct tightening torque for fasteners. When bolts are to be tightened or replaced, refer to this chart to determine the grade of bolts and the proper torque except when specific torque values are assigned in manual text. RECOMMENDED TORQUE IN FOOT POUNDS UNLESS OTHERWISE STATED IN THE MANUAL* RMB 1660 11/10 © 2010 Alamo Group Inc. Maintenance Section 5-7 MAINTENANCE NOTE: These values apply to fasteners as received from supplier, dry or when lubricated with normal engine oil. They do not apply if special graphitized or molydisulphide greases or other extreme pressure lubricants are used. This applies to both UNF fine and UNC coarse threads.
