Daily Maintenance Checklist Important: Duplicate this page for routine use. Maintenance Check Item For the week of: Mon. Tues. Wed. Thurs. Fri. Check the safety interlock operation. Check the parking brake operation. Check that pivot joints operate freely. Check the fuel level. Check the engine oil level. Check the air filter. Clean the engine cooling fins. Check for unusual engine noises. Check for unusual operating noises. Check the reel-to-bedknife adjustment. Check the height-of-cut adjustment.
Engine Maintenance Engine Oil The crankcase must be filled with approximately 20 fluid ounces of proper viscosity oil before staring. The engine uses any high-quality oil having the American Petroleum Institute - APl - “service classification" SF, SG, SH or SJ. Oil viscosity - weight - must be selected according to ambient temperature. Figure 21 illustrates the temperature/viscosity recommendations. Figure 22 1. Oil level gauge 2. Drain plug 2. Remove oil level gauge by rotating it counterclockwise. 3.
3. Push down on handle to tip mower and engine backward, allowing all oil to run into drain pan. 4. Install drain plug and refill crankcase with the specified oil; refer to Checking the Oil Level. Servicing the Air Cleaner Service Interval: Every 25 hours Every 100 hours 1. Make sure wire is off spark plug. Figure 25 2. Remove wing nuts securing air cleaner cover to air cleaner and remove cover. Clean cover thoroughly (Figure 24). 1. Foam element 2. Paper element 4.
Fuel System Maintenance electrodes because engine damaged could result from grit entering the cylinder. 3. Set air gap at 0.028-0.032 inch (Figure 27). Install correctly gapped spark plug and tighten firmly to 17 ft.-lb. Cleaning the Fuel Filter Service Interval: After the first 25 hours Every 50 hours 1. Close fuel shut off valve and unscrew bowl from filter body (Figure 28). Figure 27 Figure 28 1. Shut-off valve 2. Bowl 2. Clean bowl and filter in clean gasoline and install.
Electrical System Maintenance Drive System Maintenance Servicing the Interlock Switch Checking the Transmission Fluid Level Use the following procedure if the switch needs adjustment or replacement. Service Interval: Every 50 hours 1. Make sure the engine is off and traction lever is Disengaged. The transmission is filled at the factory with approximately 94 fluid ounces of Mobil Dexron lll automatic transmission fluid. 2. Engage traction lever until it contacts neutral stop (Figure 29).
Brake Maintenance 1. Place a drain pan at the rear of the machine. 2. Remove the drain plug from the rear of the transmission (Figure 31). Adjusting the Service/Parking Brake If service/park brake slips when operated, an adjustment is required. 1. Move service/parking brake lever to Off position. 2. To increase cable tension, loosen front cable jam nut and tighten back cable jam nut (Figure 32) until a force of 11–14 lb. is required to engage brake. Force to be measured at lever knob.
Belt Maintenance 3. To adjust belt tension: A. Loosen the bearing housing mounting nuts (Figure 35). Adjusting the Belts Make sure belts are properly tensioned to assure proper operation of the machine and unnecessary wear. Check belts frequently. Reel Drive Belt (Reel) 1. Remove the belt cover mounting fasteners and belt cover to expose belt (Figure 33). Figure 35 1. Reel drive belt 2. Bearing housing mounting nuts B. Using a 3/8 inch drive torque wrench, rotate the bearing housing with 35-40 in.-lb.
Reel Drive Belt (Transmission coupler) 1. Remove the belt cover mounting fasteners and belt cover to expose belt (Figure 37). Figure 39 1. Reel drive belt Figure 37 2. Bearing housing mounting nuts B. Using a 3/8 inch drive torque wrench, rotate the bearing housing with 35-40 in.-lb. of torque to set belt tension (Figure 40). 1. Belt cover 2. Check tension by depressing belt (Figure 38) at mid span of pulleys with 4 ± 1 lb. of force. Belt should deflect 3/16 to 5/16 inch (4.8 to 7.9 mm).
Figure 41 Figure 43 1. Traction drive belt cover 1. Tang washer 2. Check tension by depressing belt (Figure 42) at mid span of pulleys with 4 ± 1 lb of force. Belt should deflect 3/16 to 5/16 inch (4.8 to 7.9 mm). If the deflection is incorrect, proceed to next step. 2. Idler bracket bolt B. Using a 3/8 inch drive torque wrench, rotate the idler bracket with 35-40 in.-lb. of torque to set the belt tension (Figure 44).
Controls System Maintenance Adjusting the Traction Control If traction control does not engage or it slips during operation, an adjustment is required. 1. Move traction control to Disengaged position. Figure 46 2. To increase cable tension, loosen front cable jam nut and tighten back cable jam nut (Figure 45) until a force of 12-16 lb. is required to engage traction control. 1. Reel control cable 3. Tighten front cable jam nut. 4. Check control operation. Measure the force at the control knob.
Cutting Unit Maintenance Separating the Cutting Unit from the Traction Unit 1. Place the mower on its drums on a level surface. 2. Lower kick stand. Insert a 1/4" dia. pin or equivalent into frame hole above kick stand mounting bolt (Figure 47). Figure 49 1. Transmission coupling 7. Reverse procedure to install cutting unit. Note: When tightening the pivot arm mounting fasteners, use an adjustable end wrench to hold the pivot arm parallel to the side plate (Figure 50). Figure 47 3. Kick stand 1.
Figure 51 1. Spacer 2. Sideplate mounting flange 3. Roller bracket Figure 53 • Position the spacer below the sideplate mounting flange when height of cut settings range from 1/8" to 1" (Figure 52). 1. Sideplate mounting bolts Important: Whenever the cutting unit has to be tipped to expose bedknife/reel, prop up rear of cutting unit to make sure nuts on back end of bedbar adjusting screws are not resting on work surface.
from the front, parallel to the bedknife. A slight drag will be noted as the paper is pulled. Figure 55 Figure 56 1. Rear roller bracket 2. Height-of-cut arm Note: Each time adjusting screw is rotated one click clockwise, the bedknife moves .0007 inch closer to reel. Do not overtighten the adjusting screws. 3. Locknut 4. Adjusting screw 2. Loosen nut on gauge bar (Figure 57) and set adjusting screw to desired height-of-cut. Distance between bottom of screw head and face of bar is height-of-cut. 5.
Figure 58 Figure 59 1. Cut-off bar 4. Rotate adjusting screw until roller contacts front of gauge bar. Adjust both ends of roller until entire roller is parallel to the bedknife. 2. Insert .060 inch feeler gauge between top of reel and bar and tighten screws. Ensure bar and reel are equal distance apart across complete reel. Important: When set properly, the rear and front rollers will contact the gauge bar and the screw will be snug against the bedknife.
Setting the Machine to Match Turf Conditions Use the following table to set the machine to match turf conditions.
Use the following table and Figure 60 to set the rate of clip. Clip (Refer to Figure 60 for pulley locations.) Drive pulley number of teeth Driven pulley number of teeth 11 Blade Clip 8 Blade Clip 27 22 .14 inches (standard) .19 inches 22 22 .16 inches .24 inches 22 27 .21 inches .29 inches The reel is shipped with one 27 tooth and one 22 tooth pulley. To get a .16 inch clip, you must purchase a 22 tooth pulley. The clip can only be changed on the reel drive (Figure 60).
Note: For a better cutting edge, run a file across the front face of the bedknife when the lapping operation is completed. This will remove any burrs or rough edges that may have built up on the cutting edge. 2. Secure bedbar to each side plate with bedbar bolts (jam nuts on bolts) and 8 washers. A nylon washer is to be positioned on each side of side plate boss. Place a steel washer outside each of the nylon washers. Torque bolts to 240-320 in.-lb. 3.
Storage 1. Remove grass clippings, dirt, and grime from the external parts of the entire machine, especially the engine. Clean dirt and chaff from the outside of the engine’s cylinder head fins and blower housing. Important: You can wash the machine with mild detergent and water. Do not pressure wash the machine. Avoid excessive use of water, especially near the shift lever plate, and engine. 2. For long-term storage (more than 90 days) add stabilizer/conditioner additive to fuel in the tank. A.
