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.
SAFETY The rotating parts of this machine continue to rotate even after the PTO has been turned off. The operator should remain in the operator’s seat for 60 seconds after the brake has been set, the PTO disengaged, the tractor turned off, and all evidence of rotation has ceased. (S3PT-10) “Wait a minute...Save a life!” Never crawl under a raised Implement supported solely by the Tractor 3-Point hitch.
SAFETY Always read carefully and comply fully with the manufacturer’s instructions when handling oil, solvents, cleansers, and any other chemical agent. (SG-22) 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.
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.
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.
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 completelystopped. (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.
SAFETY 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.
SAFETY 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) Do not mow with two machines in the same area except with Cab tractors with the windows closed.
SAFETY DO NOT allow any person under a folded wing unless wing is securely locked up or supported. DO NOT approach the Implement unless the Tractor is turned off and all motion has ceased. Never work under the frame work, or any lifted component unless the implement is securely supported or blocked up. A sudden or inadvertent fall by any of these components could cause serious injury or even death.
SAFETY On a fully-assembled unit, do not remove the Wing Retaining Strap until hoses are attached to the tractor and the Wing Cylinders are filled with oil. Lower the Wings slowly and carefully. Keep bystanders away during operations. (STI-05) Transporting Safety Instructions and Practices (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.
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.
SAFETY Make sure the PTO shield, integral driveline shields, and input shields are installed when using PTO-driven equipment. Always replace any shield if it is damaged or missing. (S3PT-8) Relieve hydraulic pressure prior to doing any maintenance or repair work on the Implement. Place the Implement on the ground or securely blocked up, disengage the PTO, and turn off the tractor engine. Push and pull the Remote Cylinder lever in and out several times prior to starting any maintenance or repair work.
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) Perform service, repairs and lubrication according to the maintenance section.
SAFETY Always disconnect the main PTO Driveline from the Tractor before performing service on the Mower. Never work on the Mower with the tractor PTO driveline connected and running. Blades or Drivelines could turn without warning and cause immediate entanglement, injury or death.

OPERATION SECTION Operation Section 4-1 © 2011 Alamo Group Inc.
OPERATION ALAMO INDUSTRIAL INTERSTATER OPERATING INSTRUCTIONS OPERATION Alamo Industrial Interstater flail mowers are manufactured with quality material by skilled workers. These mowers are designed for cutting grass and small weeds. The mower is equipped with protective deflectors to prevent objects being thrown from the mower by the blades, however, no shielding is 100% effective. All shields, guards, and deflectors equipped on the mower must be maintained in good operational condition.
OPERATION 1. Standard Equipment and Specifications INTERSTATER 02/11 © 2011 Alamo Group Inc.
OPERATION 2.OPERATOR REQUIREMENTS OPERATION Safe operation of the unit is the responsibility of a qualified operator. A qualified operator has read and understands the implement and tractor Operator’s Manuals and is experienced in implement and tractor operation and all associated safety practices. In addition to the safety messages contained in this manual, safety signs are affixed to the implement and tractor.
OPERATION 3. TRACTOR REQUIREMENTS In addition to tractor horsepower and size required to operate the boom unit, the tractor must also be properly equipped to provide operator protection, to alert approaching vehicle drivers of the tractor’s presence, and to ensure tractor stability when mowing with the boom fully extended. Tractor Requirements and Capabilities • • ASAE approved Roll-Over Protective Structure (ROPS) or ROPS cab and seat belt. Tractor Safety Devices .....................
OPERATION 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.
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) Do not mount or dismount the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all moving parts are completelystopped. (SG-12) Before dismounting the tractor, idle the tractor engine down, disengage the head and retract the boom arm to the transport position.
OPERATION 5. STARTING THE TRACTOR The operator must have a complete understanding of the placement, function, and operational use of all tractor controls before starting the tractor. Review the tractor operator’s manual and consult an authorized dealer for tractor operation instructions if needed.
OPERATION Always shut the Tractor completely down, place the transmission in park, and set the parking brake before you or anyone else attempts to connect or disconnect the Implement and Tractor hitches. (S3PT-15) 6.1 Connecting the Mower A-Frame to the Tractor 6.2 Safety Tow Chain If the mower is towed on a public roadway, a safety chain with tensile strength equal to or greater than the gross weight of the mower must be connected between the tractor and mower.
OPERATION 7. SETTING THE MOWER OPERATION Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make a more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow the contour of uneven terrain. NOTE: Avoid very low cutting heights, striking the ground with the blades gives the most damaging shock loads and will cause damage to the mower and drive.
OPERATION 7.1 Roller Height Adjustment Hydraulic Cylinder Priming Hydraulic Cylinders must be filled with hydraulic oil before releasing the wing transport locks to lower the mower. Hydraulic cylinders and lines are filled by holding the valve control levers in the raised position until the cylinders fully extend then place the control lever in the float position.
OPERATION 7.2 Leveling Deck OPERATION To Facilitate a safe and efficient mowing operation, the mower should be operated parallel to the ground at all times. Never operate if front or rear of mower is tilted upward. Objects may be discharged at high speeds causing possible injury or even death. Adjust Top Link to level mower roller adjustment. Side Skid Shoes should always be parallel to ground throughout the full adjustment range.
OPERATION When fitting the mower to the tractor, the telescoping driveline must be inspected to ensure that at its most compressed position, the profiles do not “bottom out”, and when at its farthest extended position, there is sufficient engagement between the profiles to operate safely. At its shortest length, there must be at least a 1” clearance between each profile end and opposite profile universal joint. At its farthest operating extension, a minimum profile engagement of 12” must be maintained.
OPERATION Shorten the driveline profiles as follows: • • OPERATION • • • • • Remove the driveline from the tractor. Position the mower to the point with the shortest distance between the tractor PTO shaft and cutter gearbox. Shut down the tractor and securely block the mower in this position. Pull driveline apart and reattach yoke to PTO shaft. Hold driveline sections parallel to one another and measure back 1” from yoke of each shaft and place mark on opposite section. Cut this length off with a saw.
OPERATION DO NOT allow any person under a folded wing unless wing is securely locked up or supported. DO NOT approach the Implement unless the Tractor is turned off and all motion has ceased. Never work under the frame work, or any lifted component unless the implement is securely supported or blocked up. A sudden or inadvertent fall by any of these components could cause serious injury or even death. (STI-03) 9.
OPERATION 9.2 Mower Pre-Operation Inspection/Service OPERATION Before each mower use, a complete inspection and service is required to ensure the mower is in a good and safe working condition. Damaged and/or broken parts should be repaired and/or replaced immediately. To ensure the mower is ready for operation, conduct the following.
OPERATION • • • • • • • • • • • Ensure rubber deflectors are in position and not damaged. Replace worn, broken, and missing sections immediately. Ensure the rollers are in good condition and rotate freely. Ensure the driveline integral shield is in good condition and rotate freely. Inspect that all bolts and screws are in position and are properly torqued. OPS-F- 0004 Inspect the condition of the wings and rear section drive belts.
OPERATION • OPERATION • • • • • Inspect oil level in gearbox and replenish if needed. A low oil level is a warning sign that the gearbox may be cracked or its seal is damaged and needs to be replaced. Check the oil level in tank and replenish if need. NOTE: Do not fill the tank with oil above the level of the sight gauge. Over filling the tank with oil after initial filling may result in oil being discharged through the air filter on the top of the hydraulic tank.

Make sure the mower is resting on the ground or securely blocked up and all hydraulic pressure has been relieved. Condition at Start of Shift Item Specific Comments if not O.K.
OPERATION 10. DRIVING THE TRACTOR AND IMPLEMENT Safe tractor transport requires the operator possess a thorough knowledge of the model being operated and precautions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the weight of the implement and the tractor operating controls are set for safe transport. To ensure safety while driving the tractor with an attached implement, review the following.
OPERATION 10.1 Starting the Tractor OPERATION 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 10.2 Brake and Differential Lock Setting Make sure the tractor brakes are in good operating condition.
OPERATION 11. Operating the Mower Wings Raising to Transport Position 1. With tractor engine running, place ON/OFF switch(s) in "OFF" position and wait for cuttershaft(s) to stop rotating. 2. Pull LIFT control lever rearward until lift frame is as high as it will go. 4. Push LIFT control lever forward enough to lower unit slowly. Bar on cylinder support must pass through bracket on unit as shown in Figure 268. 5. Make certain that all control levers are in "HOLD" position when transporting unit.
OPERATION When the Wings are folded for transport, the center of gravity is raised and the possibility of overturn is increased. Drive slowly and use extreme caution when turning on hillsides. Overturning the Implement could cause the Implement to overturn the Tractor and vice versa resulting in serious injury or even death. Never fold wings on a hillside...the Implement or unit may overturn. (STI-02) OPERATION Lowering into Operating Position Ensure that ON/OFF switch(es) is (are) in "OFF" position.
OPERATION 11.1 Engaging and Disengaging the Power Take Off (PTO) and Wings Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement must be lowered to the mowing position. 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.
OPERATION OPERATION 11.2 Driving the Tractor and Implements Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the tractor and units. Moving slowly at first will also prevent the tractor from rearing up and loss of steering control. The tractor should never be operated at speeds that cannot be safely handled or which will prevent the operator from stopping quickly during an emergency.
OPERATION 11.3 Crossing Ditches and Steep Inclines Damage resulting from over-collapse of the driveline’s inner profile and its outer housing may allow the driveline to come loose from the Tractor which could cause bodily injury to the operator or bystanders and/or extensive damage to the Tractor or Implement. OPS-R-0020 When confronted with an incline or ditch, do not approach from an angle which is perpendicular or straight on as damaged to over collapse of the driveline may occur.
OPERATION OPERATION Inclines and ditches should be approached along a line which is at an angle as shown. This type of path will reduce the possibility of over-collapse of the driveline and resulting damage. If the gradient is so steep that such an approach increases the possibility of a tractor roll-over, select an alternate crossing path.
OPERATION Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating parts of the mower head. These items could then swing outside the housing at greater velocities than the blades. Such a situation is extremely hazardous and could result in serious injury or even death. 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) 12.
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.
OPERATION 12.4 Operating the Mower Only operate the mower from the tractor operator’s seat with the seatbelt securely fastened. The tractor must be equipped with a ROPS in the raised position or a ROPS cab. 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.
OPERATION 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. OPERATION -Do Not drive into burning debris or freshly burnt areas. -Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating.
OPERATION 13. DISCONNECTING THE MOWER FROM THE TRACTOR After disconnecting the 3 lift points, remove the mower driveline from the tractor PTO shaft. Lay the driveline down carefully to avoid damaging the driveline or its shield. Do not let the driveline fall into mud or dirt, which can contaminate the bearing and shorten the life of the driveline.
OPERATION MOWER STORAGE It is recommended that the mower be stored with the center section and both wings fully lowered to ground level. If the mower is stored with the wings in the raised position, select a level area and install wing transport braces to prevent the wings from falling BEFORE disconnecting the mower hitch from the tractor. OPERATION Properly preparing and storing the mower at the end of the season is critical to maintaining its appearance and to help ensure years of dependable service.
OPERATION 14. TRANSPORTING THE TRACTOR AND IMPLEMENT Inherent hazards of operating the tractor and implement and the possibility of accidents are not left behind when you finish working in an area. Therefore, the operator must employ good judgement and safe operation practices when transporting the tractor and implement between locations. By using good judgement and following safe transport procedures, the possibility of accidents while moving between locations can be substantially minimized.
OPERATION OPERATION Before transporting the tractor on a public roadway or boarding a trailer for transport, the tractor brake pedals should be locked together. Locking the pedals ensures that both wheels brake simultaneously while stopping, especially when making an emergency stop. Use extreme caution and avoid hard applications of the tractor brakes when towing heavy loads at road speeds. Never tow the implement at speeds greater than 20 MPH (32 kph).
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. (SG-6) Make sure that all tractor flashing warning lights, headlights, and brake/tail lights are functioning properly before proceeding onto public roads.
OPERATION OPERATION Reduce speed before turning or applying the brakes. Ensure that both brake pedals are locked together when operating on public roads. OPS-U- 0023 15. 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.
OPERATION Once the tractor has been loaded onto an adequate rated trailer, raise the side flail/flails into transport position and make sure the control levers are in the center lock position. Ensure the wing start/stop buttons are pushed in the stop position and shut down tractor. Remove key and exit the tractor. Dual Wing When completely out of the tractor close window and strap window closed as shown in Figure Ops1464. Use both hands for support when getting on and off the Tractor.
OPERATION OPERATION Before tying down tractor with chains secure the flail wings together with a shipping strap. Refer to Figure Ops-1465 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.
OPERATION 16. TROUBLE SHOOTING GUIDE Problem Possible Cause Remedy Excessive Vibrations Check gearbox bolts. Check for missing knives on cutter shaft. Check to see if knives are free swinging. Blade broken or bent. Cuttershaft bent. Drivelines not phased correctly. Implement & Tractor yokes must be in line. Tighten if loose Replace missing knives Low on lubricant. Improper type lubricant. Excessive trash build-up around gearbox. Bearing or gears set up improperly. Fill to level plug.
OPERATION OPERATION Knives Wear Too Fast Cutting in sandy conditions. Cutting in rocky conditions. Soft “will fit” knives. Increase cutting height. Increase cutting height. Use genuine Alamo Industrial knives. Hydraulic Cylinder Will Not Operate Not enough pressure. Valve not connected properly Quick coupler not completely connected. Check Pressure Re-plumb valve.

Mnt-FL-0009 INTERSTATER 02/11 © 2011 Alamo Group Inc. Maintenance Section 5-5 MAINTENANCE 5. Remove filter. Inspect material trapped by the filter. It can indicate parts wear in the system.
MAINTENANCE CUTTER UNIT A. GENERAL The INTERSTATER electrical circuit controls the flow of oil to the hydraulic motor on the cutter unit. The motor control valve relies on a solenoid to control the spool within the valve and direct the flow of oil. MAINTENANCE When the mower ON/OFF switch is in the "ON" position, current flows to the solenoid which positions the spool to direct the oil flow from the pump to the motor. The oil then turns the motor which drives the cuttershaft.
MAINTENANCE REPLACING CUTTER UNIT DRIVEBELTS NOTE: Belts must be replaced as a set. DO NOT replace just one belt. 1. Place unit on ground or support securely. 2. Remove belt guard. 3. Remove idler arm spring. 5. Pivot motor-mounting bracket assembly. Remove old belts and install new ones. 6. Reinstall front mounting bolt then secure motor mounting bracket to unit. 7. Reinstall idler arm spring and belt guard. ADJUSTING CUTTING HEIGHT 1.
MAINTENANCE ROLLER BEARING REPLACEMENT MAINTENANCE Securely support mower while removing and installing roller assembly. 1. Remove roller and both bearing and bracket assemblies from mower. Lift the mower only high enough to remove the roller assembly. If installing a roller with pre assembled bearing and bracket assemblies, remove the old roller, proceed to step 11. 2. Slide bearing and bracket assemblies off each end of roller. If replacing with new bearing and bracket assemblies, proceed to step 9. 3.
MAINTENANCE CUTTERSHAFT BEARING REPLACEMENT Outboard Bearing 1. Lift cutter unit to maximum horizontal height; then securely support ends of cutterhousing. 2. Remove enough knives to place a floor jack under center of cuttershaft. NOTE: The cuttershaft must remain supported while changing bearings. 4. Remove outboard fender. 5. Remove fasteners securing bearing and housing assembly to cutterhousing, then remove bearing and housing assembly.
MAINTENANCE MAINTENANCE Inboard (Drive) Bearing 1. Remove spring from idler arm. Fig. Mnt-FL0013 2. Remove motor mounting bracket fasteners, at the cutterhousing. Pivot motor- mounting bracket 3. Remove fasteners that secure pulley to cuttershaft. Remove pulley and key. 4. Remove fasteners securing inboard bearing and housing assembly to cutter- housing, then remove bearing and housing assembly.
MAINTENANCE CHANGING TO FORWARD OR REVERSE ROTATION Wing Mowers Rear Mower To change direction of cuttershaft rotation for the rear mover, three left hand parts are required. A belt guard, an outboard bearing plate and a idler pulley arm. (Consult parts book for these part numbers). Remove the cuttershaft and turn 180 deg. Remove the gearbox cuttershaft drive pulley and outboard bearing plate, (using the proper bearing plate) mount the plate to opposite side of mower housing.
MAINTENANCE HYDRAULICS General The INTERSTATER hydraulic system consists of two circuits. The power circuit drives the cuttershaft. The control circuit lifts and tilts the cutter unit. MAINTENANCE A tractor with a cutter unit installed on each side will have two independent power circuits with two sets of lift and tilt cylinders, and one control circuit with a four-section control valve (instead of a two section valve).
MAINTENANCE Troubleshooting The following shows various problems, the apparent cause, and the recommended procedure for their correction. POSSIBLE CAUSE REMEDY Mower will not rotate In line Fuse blown. Safety switch not making contact. Broken Drivebelts. On/Off Switch bad. Insufficient voltage through Solenoid. Solenoid Spool will not shift completely. Replace Fuse. Adjust or replace Safety Switch. Replace Belts Replace On/Off Switch Check Coil and Wires. Mower will not stop.
MAINTENANCE POWER CIRCUIT The pump unit assembly is made up of the oil reservoir, and hydraulic pump. The pump is driven by the engine crankshaft through a drive shaft. Therefore, oil is being pumped whenever the engine is running. When the mower is off, oil is directed to the reservoir by the solenoid motor control valve and does not flow to the cutter motor. Cooling is provided by patented in frame cooling tubes in the wing mowers.
MAINTENANCE Reservoir The reservoir stores hydraulic system oil. The breather cap which is mounted on top of the reservoir prevents a pressure buildup or vacuum from occurring in the tank as oil level changes. Their is also an oil filler cap which is used to fill the reservoir with oil. To help prevent dirt from entering the tank, clean the top of the reservoir before removing the cap. THE BREATHER CAP HOLDS APPROX 11 PSI PRESSURE IN TANK.
MAINTENANCE Checking Solenoid Valve 1. With engine running, turn the mower ON/OFF switch in the "ON" position. Check voltage level at the solenoid. 2. If it is less than 12 volts, check wiring and ground connections. Checking ground wire is as important as checking the hot wire. If voltage is sufficient, the solenoid valve is bad and will need to be replaced. MAINTENANCE Hydraulic Pump DISASSEMBLY 1. Disconnect all hydraulic lines. Remove pump assembly from tractor. 2.
MAINTENANCE Inspection of Hydraulic Pump 1. Inspect flat surface of the backplate. The finish on the piston block side should be smooth and free of grooves. DO NOT LAP BACKPLATE WEAR SURFACE. The backplate should be replaced if it shows any of the wear characteristics outlined above. Inspect the needle bearing in the backplate. If the needles are free of excessive play and remain in the bearing cage, there is no need to replace the bearing. 2. Inspect the piston block.
MAINTENANCE MAINTENANCE POSSIBLE TROUBLE CAUSES REMEDIES System will not operate in either direction. Oil supply low. Oil Filter clogged. Oil too heavy. Drive Coupling broken. Check oil level and fill. Replace Filter Element. Use proper viscosity oil. Inspect Coupling for sheared Spline Spline or Key. System noisy. Air in system due to low oil level. Loose Suction Line. Clogged Suction Filter. Internal Pump or Motor damage. Fill in reservoir to sight glass. Tighten Fittings. Replace Filter Element.
MAINTENANCE Hydraulic Motor Disassembly Clean outside of unit thoroughly. Refer to Hydraulic Motor illustration in the Parts Listing section. 2. Clamp shaft in a protected jaw vise with backplate end up. 3. Remove six cap screws from backplate. 4. Use a plastic mallet and tap the backplate to loosen it. 5. Remove o-ring from backplate. 6. Remove the complete piston block assembly from the housing assembly. 7. Remove piston assemblies, spider, and pivot form piston block assembly. 8.
MAINTENANCE MAINTENANCE Inspection 1. Wash all parts thoroughly in a suitable solvent. 2. Examine needle bearings in housing and backplate. 3. Inspect thrust washers and thrust bearing. All surfaces should be free of any signs of wear or fretting. 4. Inspect spider and pivot; conical surfaces should be free of wear and score marks. 5. Inspect the pistons: the O.D. surface should be smooth and free of scoring. The shoes should be snug fit to the piston.
MAINTENANCE Troubleshooting CAUSES REMEDIES Motor turns while unloaded but slows down or stops when load is applied Scored backplate. Remove backplate and examine surface condition of flat area; if scored, replace backplate. DO NOT LAP. Disassemble motor, examine condition of shoes on pistons; replace pistons as a complete set if necessary. DO NOT LAP Check Relief Valve for proper pressure setting; adjust pr replace Relief Valve. Scored or worn piston shoes. Low Relief Valve pressure.
MAINTENANCE CONTROL CIRCUIT Lift and Tilt Cylinders MAINTENANCE Hydraulic cylinders change the position of the cutter unit. The lift cylinder raises and lowers the unit by changing position of the lift frame. To lift unit, oil is supplied to rod side of cylinder. Gravity lowers unit when lift levers are in "DOWN" position. The tilt cylinder changes the angle of the cutter unit. Oil is supplied to both ends of the cylinder and provides power to tilt the unit up or down.
MAINTENANCE Hydraulic Gear Pump NOTE: The gear pump is not used when tractor hydraulics are used to power the control circuit. Sectional Control Valve The control valve directs oil flow from the gear pump to the hydraulic cylinders. In the "HOLD" position, the spool blocks oil flow to the cylinders which prevents movement, and directs oil through the valve back to the reservoir. When the spool is shifted, oil flows to one side of the cylinder while the other side is opened to the return line.
MAINTENANCE Checking Relief Valve Pressure 1. To check the relief valve pressure setting, remove inlet hose at the control valve. Install a tee fitting and reconnect the hose to a pressure gauge. 2. Check for proper tension on front drive belts (1/4 inch play at midpoint). 3. Start engine and run at low idle. MAINTENANCE 4. Raise the Tilt cylinder and note the pressure when the cylinder bottoms. 5. The pressure should be the same on both circuits, 1200 psi.
MAINTENANCE External Coil Slip Disk Replacement A. TO DISASSEMBLE EXTERNAL COIL SPRING CLUTCH (Figure Mnt-FL-0024) Before beginning disassembly, remove or fold shields out of the way and clean off dirt and trash from the area. 1. Remove two Attaching Bolts (6). Remove Clutch Assembly from shaft of Gearbox. Leave Driveline or Driveline Half attached to Clutch. 3.
MAINTENANCE Slip Clutch A slip clutch is incorporated in the PTO driveline. It is designed to slip, absorb the shock load, and protect the driveline. MAINTENANCE After the first hour of operation, the slip clutch should be checked for overheating. After this first check, the slip clutch should be checked weekly or anytime there is overheating. To adjust the slip clutch, tighten the spring bolts 1/8 (maximum) turn at a time.
MAINTENANCE SEASONAL CLUTCH MAINTENANCE It is important that the clutch lining plates slip when an obstacle or load heavier than clutch setting is encountered. Therefore, if the machine sits outside longer than 30 days and is exposed to rain and/or humid air it is important to make sure that the clutch lining plates are not rusted/corroded together. Before using the mower use the following procedure to make sure the clutch will slip and give the overload protection required. 1.
MAINTENANCE Proper Torque 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. MAINTENANCE RECOMMENDED TORQUE IN FOOT POUNDS UNLESS OTHERWISE STATED IN THE MANUAL* NOTE: These values apply to fasteners as received from supplier, dry or when lubricated with normal engine oil.
