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 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) The rotating parts of this machine continue to rotate even after the PTO has been turned off.
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. Children can cause the Implement to shift or fall crushing themselves or others.
SAFETY 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) 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) Do not operate the implement while wearing loose fitting clothing.
SAFETY SAFETY 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.
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.
SAFETY SAFETY 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.
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 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.
SAFETY SAFETY Rotary Mowers are capable under adverse conditions of throwing objects for great distances (300 feet or more) and causing serious injury or death. Follow safety messages carefully.
SAFETY Connecting or Disconnecting Implement Safety Instructions and Practices 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.
SAFETY 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.
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. Before transporting the Tractor and Implement, determine the proper transport speeds for you and the equipment.
SAFETY Secure the Implement for transport before traveling on public roads. For pull-type Implements, secure the center axle using cylinder stops or transport pin and properly attach a safety chain between the Implement and Tractor. Secure wings in upright position on folding Implements using wing transport locks. (STI-7) SAFETY Always keep a careful lookout and use extreme care when working around overhead obstructions and electrical power lines. The Implement wing can be over 10 feet high.
SAFETY Never work under the Implement, the framework, or any lifted component unless the Implement is securely supported or blocked up to prevent sudden or inadvertent falling which could cause serious injury or even death. (SG-14) Never attempt to lubricate, adjust, or remove material from the Implement while it is in motion or while tractor engine is running. (SG-20) Perform service, repairs and lubrication according to the maintenance section.

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 The tractor used to operate the mower must have the power capacity to lift, pull, and operate the Power Take Off (PTO) at the mower’s rated speed while traveling at a ground speed between 2 and 5 MPH. Operating the mower with a tractor that does not meet the following requirements may cause tractor or mower damage and be a potential danger to the operator and passersby.
OPERATION 3.3 Tractor Horsepower The horsepower required to operate the mower depends on several operating factors including the vegetation to be cut, terrain condition, operator experience, condition of the mower and tractor, and others. For most mowing conditions, the FL10 NITRO mower requires a tractor with a minimum of 40 HP and the FL15 NITRO mower requires a tractor with a minimum of 50 HP. Operating the mower with a tractor that does not have adequate power may damage the tractor engine.
OPERATION 3.6 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 3.
OPERATION 3.8 Tire Spacing OPERATION Tractor tires should be set a minimum of 60”(1.5 mm) apart measured from inside of tire to inside of tire. Refer to the tractor Operator’s Manual or consult an authorized dealer for instructions to change tractor tire spacing. OPS-R- 0062 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.
OPERATION 4.2 Dismounting the Tractor Before dismounting, park the tractor and implement on a reasonably level surface, apply the parking brake, idle the engine down, disengage the PTO, and lower the implement to the ground. Shut down the tractor engine according to the operator’s manual, remove the key, and wait for all motion to completely stop. Never leave the seat until the tractor, its engine and all moving parts have come to a complete stop. Use hand rails and steps when exiting the tractor.
OPERATION Never run the Tractor engine in a closed building or without adequate ventilation. The exhaust fumes can be hazardous to your health. (SG-23) OPERATION 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) 6. CONNECTING THE MOWER TO THE TRACTOR Use extreme caution when connecting the mower to the tractor.
OPERATION 4. 6. 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. This will help control the implement in the event the tongue becomes disconnected from the drawbar. Make sure the chain is attached to a secure location on the tractor and not to an intermediate support.
OPERATION to outlets of the same tractor hydraulic port. Connect the mower hydraulics to the control valve bank with the center section line to the right port. Connect the wing cylinder lines to the control valve positioned to correspond with the left and right wing. OPERATION To activate the 3-spool hydraulic control valve, tie the tractor’s hydraulic control lever back to keep hydraulic oil continuously fed to the valve bank.
OPERATION 7.1 Setting Deck Height LEVELING DECK CENTER SECTION 1. 2. 4. 5. 6. LEVELING WING SECTIONS WITH CENTER To level the wing sections with the deck center, adjust the leveling screw between the wing axle and the center axle. To lower the wing, loosen the jamnut and shorten the screw assembly, lengthen the screw assembly to raise the wing. After wings are leveled, retighten jamnuts to maintain settings. FN10/FN15 NITRO 02/10 © 2010 Alamo Group Inc. Operation Section 4-13 OPERATION 3.
OPERATION 7.2 Setting Deck Pitch OPERATION To facilitate safe and efficient operation, the mower should be operated with the deck approximately 3/4” LOWER IN THE FRONT THAN THE REAR. Operating the mower at this pitch will allow the mower to cut the grass only once and requires less work from the tractor. In addition, a more even distribution of the clippings from the rear of the mower will be achieved with this deck pitch.
OPERATION 8.1 Driveline Length Check Before operating the Implement, check to make sure the Implement input driveline will not bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and through the support bearings or downward onto the PTO shaft, breaking it off. A broken driveline can cause personal injury.
OPERATION Engagement Check Procedure OPERATION • With the driveline attached, position the mower to the point where the telescoping driveline is at its maximum extension. Completely shut down the tractor and secure in position. • Mark the inner driveline shield 1/8” from the end of the outer shield. • Disconnect the driveline from the tractor and separate the two driveline halves. • Measure the distance from the mark to the end of the inner profile.
OPERATION 8.2 Constant Velocity (CV) Driveline Mowers are equipped with a Constant Velocity (CV) driveline, the maximum turning angle between the tractor and mower must be determined to ensure the joint angle does not over-extend which can cause CV joint damage. Constant Velocity joints enable the driveline to operate smoothly with no vibrations and clattering at angles up to 80°. Angles greater than 80° will result in mechanical damage to the CV joint and mower driveline.
OPERATION The Constant Velocity PTO driveline is HEAVY (70 lbs or greater) and Special Lifting Procedures are recommended.
OPERATION 9.1 Tractor Pre-Operation Inspection/Service Refer to the tractor operator’s manual to ensure a complete pre-operation inspection and scheduled service is performed according to the manufacturers recommendations.
OPERATION The operator’s manual and safety signs affixed on the unit contain important instructions on the safe and proper use of the equipment. Maintain these important safety features on the implement in good condition to ensure the information is available to the operator at all times. • OPERATION • • • • • • • • Ensure the manual canister is secured to the equipment with the operator’s manual inside. Ensure all safety signs are in place and legible. Replace missing, damaged, and illegible decals.
OPERATION • • • • • • • • Perform scheduled lubrication as specified in the maintenance section. Inspect each gearbox oil level 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. Ensure all gearbox vents are in place and free from clogs. OPS-R-0011_A Inspect blades and blade bolts for looseness and excessive wear. Make sure the mower is securely blocked up before crawling beneath.
OPERATION • OPERATION • • • • • • Ensure each hydraulic cylinder is installed and retained correctly. Ensure the proper size pins are used to retain the cylinders in place and are secured with pins. Check for hydraulic oil leaks on the cylinders, along the hydraulic lines, and at tractor hydraulic ports.IMPORTANT: DO NOT use your hands to check for oil leaks. Use a piece of heavy paper or cardboard to check for hydraulic oil leaks.
OPERATION 9.3 Cutting Component Inspection Inspect blade pan and blade assembly for the following: OPERATION OPS-U-0031 FN10/FN15 NITRO 02/10 © 2010 Alamo Group Inc.
OPERATION Operating the mower with loose blade hardware will damage the blade holder or blades and can result in blade breakage or blade fastener failure. Broken blades or bolts can be thrown out from under the mower for distances up to 300 feet. When the blades are replaced, the fastening hardware must be replaced. Check and retighten the blade hardware after the first eight hours of operation. In severe cutting conditions, recheck the blade carrier and blade bolt torque every 50 hours.
OPERATION 9.4 Blade Bolt Inspection Inspect Blade Bolt Head daily for wear as followed: OPERATION Inspect the Blade Bolt Heads daily for abnormal wear. REPLACE BOTH BLADE BOLTS on the Blades IMMEDIATELY if either blade bolts has: • Visible cracks or • If the recessed area on blade bolt is worn off or • If Blade Bolt has gouges or chipped areas.

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 Tractor PRE-OPERATION Inspection Tractor ID#________________ Make ____________________ Date: Shift ________________ ____________________ Condition at Start of Shift Item Specific Comments if not O.K.
OPERATION 10. DRIVING THE TRACTOR AND IMPLEMENT OPERATION 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 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.
OPERATION OPERATION 10.4 Transport Position To raise mower wings, drive the unit to a level area and retract the wing hydraulic cylinders. DO NOT raise wings with the mower positioned on an embankment or other inclined position to prevent overturning the mower. After the wings are fully raised, install transport lock braces to prevent wings from inadvertently falling.
OPERATION Use extreme care when lowering or unfolding the implement’s wings. Make sure no bystanders are close by or underneath the wings. Allow ample clearance around the implement when folding or unfolding the wings. Use extreme caution around buildings or overhead power lines. (S3PT-05) 10.
OPERATION OPERATION 10.7 Crossing Ditches and Steep Inclines When crossing ditches with steep banks or going up sharp inclines, it is possible that the main driveline inner profile will penetrate into the outer housing to its maximum depth until the assembly becomes solid (driveline is at its extreme shortest length).
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. 11. OPERATING THE TRACTOR AND IMPLEMENT THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE.
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) OPERATION 11.
OPERATION Rotary Mowers are capable under adverse conditions of throwing objects for great distances (300 feet or more) and causing serious injury or death. Follow safety messages carefully.
OPERATION 11.4 PTO RPM and Ground Speed OPERATION Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Recommended speed for efficient mower performance is between 2 and 5 mph(3-8 kph). 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 PTO and desired ground speed.
OPERATION Do not mow with two machines in the same area except with Cab tractors with the windows closed. (SGM-11) 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.
OPERATION OPERATION When you get to the end of a pass, slightly raise the mower (2-4”) before turning. Never raise the mower entirely while the blades are turning. If the mower must be raised higher than 12” from ground level, disengage the tractor PTO and wait for all mower rotation to come to a complete stop before proceeding to raise the mower. NEVER raise the mower wings while the blades are turning.
OPERATION When mowing across uneven areas such as road shoulders, ditch edges, and other uneven terrain, position mower so that one support wheel is near the highest point to prevent blades from cutting into gravel or dirt which can cause rapid blade wear and extremely severe shock loads on the drivetrain resulting in rapid wear or damage to these components. Blades contacting the ground may cause objects to be thrown out from under the mower deck.
OPERATION 11.6 Shutting Down the Implement OPERATION To shut down attached mower head, first bring the tractor to a complete stop. Decrease engine RPM to idle then disengage cutterhead. The mower head will come to a complete stop within a suitable amount of time. Do not engage or disengage the cutterheads at a high RPM unless there is an emergency situation.
OPERATION Never unhitch without using the Tongue Jack. The Tongue is very heavy. Attempting to lift the Tongue without using the Tongue Jack could cause strains or other injury. Allowing the tongue to fall suddenly and unexpectedly could result in crushing injury. Use the Tongue Jack for lifting the Implement only. Overloading the Tongue Jack can cause failure with possible serious bodily injury or even death.
OPERATION 13. 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. 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 Never allow children or other persons to ride on the Tractor or Implement. Falling off can result in serious injury or death. (SG-10) If the tractor’s hydraulic pump is not independent of the tractor PTO, or if the tractor PTO has to be run to have hydraulic power, disconnect the mower driveline from the tractor PTO output shaft. Secure the driveline to the mower deck to prevent driveline damage or loss during transport.
OPERATION 14.1 Tire and Wheels OPERATION Laminated Sectional Tires are designed for conditions where puncture proof performance is required and the mower will not be transported for long distances on roadways. Transport speed for laminated tires should not exceed 15 MPH. Excessive speed can cause damage to the machine and tire sections. Laminated tires must be installed such that the rubber segments lay with the ground.
OPERATION 14.2 Transporting on Public Roadways Extreme caution should be used when transporting the tractor and mower 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.
OPERATION OPERATION Make sure that all tractor flashing warning lights, headlights, and brake/tail lights 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 are only equipped with operating lights. Consult an authorized tractor dealer for lighting kits and modifications available to upgrade the lighting on older tractor models.
OPERATION 14.3 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.

MAINTENANCE CENTER & WING GEARBOXES The Gearboxes have been filled with lubricant to the proper level prior to shipment. However, you should check the oil level using dipstick before operating, and frequently thereafter. MAINTENANCE The gearbox should not require additional lubricant unless the box is cracked or a seal is leaking. It is recommended that the dipstick be removed after every 8 to 10 hours of operation and oil added until it rises to proper level on dipstick.
MAINTENANCE GEARBOX ARRANGEMENTS (Secondary Gearboxes) FN10/FN15 NITRO 01/11 © 2010 Alamo Group Inc. Maintenance Section 5-5 MAINTENANCE All Three secondary Gearboxes have the same identical parts in them for 540 or 1000 RPM and for the left, center, or right sections. To change Gearbox from 540 to 1000 RPM, the Gear (#1) and Pinion (#2) must be reversed. Remove the Gear from the Cross Shaft and the Pinion from the vertical Output Shaft.
MAINTENANCE DRIVELINES The Drivelines and U-Joints should be inspected each morning before the mower is started. MAINTENANCE Many of the equipment components are HEAVY (70 lbs or greater) and Special Lifting Procedures are recommended. Use lifting assistance such as mechanical assistance, two people, and proper lifting techniques when connecting or installing the driveshaft to reduce the possibility of back injuries.
MAINTENANCE MAIN CV DRIVELINE SHIELD SERVICE INSTRUCTIONS Clean and grease bushing groove before the bushing is placed in the groove. Grease any remaining bushings in guard. 2. Slide guard half over driveline and insert bushing tabs into the openings in the guard. 3. Turn the bushing until it engages into the guard. 4. Push Easy Lock clip into position. The bushing and guard are now secure. 5. TO REMOVE GUARD - Use screwdriver to release Easy Lock clip.
MAINTENANCE BLADE SERVICING MAINTENANCE Inspect blades before each use to determine that they are properly installed and in good condition. Replace any blade that is bent, excessively nicked, worn, or has any other damage. Small nicks can be ground out when sharpening. Use only original equipment blades on this cutter. They are made of special heat-treated alloy steel. Substitute blades may not meet specifications and may fail in a hazardous manner that could cause injury.
MAINTENANCE BLADE SHARPENING Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as shown in FIGURE Mnt-R-0008. Always sharpen blades by grinding. DO NOT heat and pound out edge. Do not sharpen blade to a razor edge, but leave a 1/16" blunt edge. Do not sharpen back side of blade. Never work under equipment supported by a hydraulic device because it may drop if the control is actuated (even with the engine stopped) or in the event of hose failure, etc.
MAINTENANCE Blade Bolt Inspection MAINTENANCE Inspect Blade Bolt Head daily for wear as followed: Inspect the Blade Bolt Heads daily for abnormal wear. REPLACE BOTH BLADE BOLTS on the Blades IMMEDIATELY if either blade bolts has: • Visible cracks or • If the recessed area on blade bolt is worn off or • If Blade Bolt has gouges or chipped areas.
MAINTENANCE BLADE CARRIER REMOVAL Remove cotter pin and loosen slotted nut on gear box shaft. Loosen but do not remove the nut until the blade carrier is loosened. Use a suitable two-jaw gear puller to pull carrier off tapered gear box shaft. If gear puller is not available use long bar inserted through blade bolt access hole with end against rotor bar. Strike opposite end of bar with sledge hammer. Rotate blade carrier 180 degrees and repeat process.
MAINTENANCE BLADE CARRIER INSTALLATION Clean the splines on both the blade carrier and output shaft. Position carrier on the gear box output shaft and install flat washer and 1" hex nut. Tighten nut holding blade carrier to minimum 600 ft. pounds, strike the carrier on the hub several times with a heavy hammer to seat the hub. Use a suitable spacer over the nut to prevent damage to the nut and threads. Retighten the nut to 600 ft. pounds. Install and spread cotter pin.
MAINTENANCE SEASONAL CLUTCH MAINTENANCE It is important that the clutches slip when an obstacle or load heavier than the clutch setting is encountered. Before using the cutter each season, use the following procedure to make sure the clutch will slip and give the overload protection required. 1. 2. SLIP CLUTCH REPAIR PROCEDURE 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. Remove two bolts from top cover plate which holds shield bracket to gearbox. Remove locknuts #11 from bolts #12.
MAINTENANCE WHEEL HUB ASSEMBLY MAINTENANCE The Wheel Hub Assemblies need to be lubricated on a weekly basis. FIGURE MntP-R-0032. TIRES AND WHEELS Before working on any tires and wheels make certain the Cutter is jacked up high enough and securely supported. When installing laminated or airplane tires, be sure the flat side of the lug nut is against the Wheel. When installing Sectional Tires and Wheels note the direction of travel and the curvature of rubber segments in the tire (See Assembly Section).
MAINTENANCE Tongue The Tongue Hitch Pins attach the Tongue to the Center Section and should be checked for signs of wear or cracking. Replace as needed. The Drawbar 1" Bolt fastens the mower to the tractor Drawbar. When the mower is unhitched and this 1" Bolt is removed, examine for signs of cracking or wear. Replace the Drawbar 1" Bolt at first sign of either problem. FIGURE Op-1155 MAINTENANCE FN10/FN15 NITRO 01/11 © 2010 Alamo Group Inc.

KEEP all hydraulic hoses, lines and connections in GOOD CONDITION and TIGHT before applying system pressure. • RELIEVE HYDRAULIC PRESSURE before disconnecting lines or working on the system. • REMOVE and replace hose if you suspect it leaks. Have dealer test it for leaks.
MAINTENANCE Flex Wing Hydraulic Cylinder Replacement Instructions Implement Cylinders Removal and Replacement Follow these Steps: Clear the area of all personnel before lowering the wings. 2. From the tractor seat with your seat belt fastened around you, Lower the implement wings to the ground. Do Not attempt to replace the cylinder with the wings in the raised position. 3.
MAINTENANCE SKID SHOES Skid shoes are made of carbon steel to reduce wear and increase service life. Premature wear can be caused by the mower Center or Wing sections being set too low which allows the Wing Skid Shoes to drag on the ground. Dragging the Skid Shoes on the ground or running the Skid Shoes into solid objects can contribute to early frame failure on the mower. Replace worn Skid Shoes as required.
