Danger • Keep cigarettes, sparks and flames away from battery. • Make sure the ignition switch is off. • Ventilate when charging or using battery in an enclosed space.
Refer to Adjusting the Mower Level on page 41. Caution Checking the Radiator Coolant This machine produces sound levels in excess of 85 dBA at the operators ear and can cause hearing loss through extended periods of exposure. Check the cooling system level before the engine is first started. Wear hearing protection when operating this machine. Refer to Checking the Radiator Coolant, page 32.
Using the Hour Meter Warning The hour meter records the number of hours the engine has operated. It operates when the engine is running. Use these times for scheduling regular maintenance. Parking brake may not hold machine parked on a slope and could cause personal injury or property damage. 1 Do not park on slopes unless wheels are chocked or blocked Releasing the Parking Brake m–3077 Figure 10 Push forward and down on the parking brake lever to release the parking brake (Fig. 12).
6. Turn the ignition key to Start to energize the starter. When the engine starts, release the key (Fig. 16). 5. Pull wire off spark plug(s) to prevent possibility of someone accidentally starting the machine before transporting or storing machine. Important Do not engage the starter for more than 10 seconds at a time. If the engine fails to start, allow a 30 second cool-down period between attempts. Failure to follow these instructions can burn out the starter motor. 6.
The Safety Interlock System 3. Sitting on the seat, engage the parking brake, move the PTO to Off, and lock the motion control levers in neutral. Now start the engine. While the engine is running, release the parking brake, engage the PTO, and rise slightly from the seat; the engine should stop. Caution If safety interlock switches are disconnected or damaged the machine could operate unexpectedly causing personal injury. 4.
Adjusting the Height-of-Cut The farther you move the traction control levers in either direction, the faster the machine will move in that direction. The height-of-cut is adjusted from 1-1/2 to 5 in. (38 to 127 mm) in 1/4 in. (6 mm) increments by relocating the clevis pin in different hole locations. To stop, pull the motion control levers to neutral. 1. Raise the height-of-cut lever to the transport position (also the 5 in. [127 mm] cutting height position) (Fig. 19). 2 3 1 2.
To Push the Machine 5. Repeat the adjustment on the other gage wheels. 1. Disengage the power take off (PTO) and turn the ignition key to Off. Move the levers to the neutral locked position and apply the parking brake. 2. Rotate the by-pass valves counterclockwise 1 turn to push. This allows hydraulic fluid to by-pass the pump enabling the wheels to turn (Fig. 22). Important Do not rotate the by-pass valves more than 1 turn.
Warning Warning Driving on street or roadway without turn signals, lights, reflective markings, or a slow moving vehicle emblem is dangerous and can lead to accidents causing personal injury. Loading a unit onto a trailer or truck increases the possibility of backward tip–over and could cause serious injury or death. • Use extreme caution when operating a unit on a ramp. • Use only a single, full width ramp; DO NOT use individual ramps for each side of the unit.

Z Stand (Positioned in slot) • Use extreme caution when operating unit on Z Stand.
Mow at Correct Intervals 9. Remove chocks or blocks. Normally, mow every four days. But remember, grass grows at different rates at different times. So to maintain the same cutting height, which is a good practice, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height; then mow again two days later at a lower height setting. Driving off the Z Stand 1.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position.
Caution If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the ignition and disconnect the wire from the spark plug(s) before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug. Servicing the Cutting Blades Maintain sharp blades throughout the cutting season because sharp blades cut cleanly without tearing or shredding the grass blades.
3 5 4 MEASURE FROM CUTTING EDGE TO A LEVEL SURFACE 2 1 m–2539 3 Figure 29 4 M–4226 3. Rotate the opposite ends of the blades forward. Measure from a level surface to the cutting edge of the blades at the same position as in step 2 above. The difference between the dimensions obtained in steps 2 and 3 must not exceed 1/8 in. (3 mm). If this dimension exceeds 1/8 in. (3 mm), the blade is bent and must be replaced; refer to Removing the Blades and Installing the Blades, page 30. Figure 30 1.
Installing the Blades Cleaning the Paper Elements 1. Install the blade onto the spindle shaft (Fig. 30). 1. Lightly tap the element on a flat surface to remove dust and dirt (Fig. 34). Important The curved part of the blade must be pointing upward toward the inside of the mower to ensure proper cutting. 2. Inspect the element for tears, an oily film, and damage to the rubber seal. Important Never clean the paper element with pressurized air or liquids, such as solvent, gas, or kerosene.
Changing the Oil Viscosity: See the table below. USE THESE SAE VISCOSITY OILS Replace the oil every 100 hours. 1. Start the engine and let it run for five minutes. This warms the oil so that it drains better. 2. Park the machine so that the drain side is slightly lower than the opposite side to ensure that the oil drains completely. Disengage the power take off (PTO), set the parking brake, stop the engine, and remove the key. 3. Place a pan below the oil drain.
4. Apply a thin coat of new oil to the rubber gasket on the replacement filter (Fig. 37). Danger Rotating shaft and fan can cause personal injury. • Do not operate the machine without the covers in place. • Keep fingers, hands and clothing clear of rotating fan and drive shaft. • Shut off the engine and remove the ignition key before performing maintenance. 3 1 2 Caution m–1256 Swallowing engine coolant can cause poisoning. Figure 37 1. Oil filter 2. Gasket • Do not swallow engine coolant.
Cleaning the Cooling System 1. Position the machine on a level surface, stop the engine, and set the parking brake. Clean the cooling system daily before each use. 2. Tilt the seat up and tilt the engine hood forward. 1. Position the machine on a level surface, stop the engine, and set the parking brake. 3. With the engine cool, drain the coolant by loosening the drain cock in the right rear corner (Fig. 39). Important Before starting the engine, clean grass from the pump drive belt compartment.
Servicing the Spark Plug 9. With the radiator cap off, tilt the engine cover down and put the seat down. Start the engine. Run the engine until it is warm. Check the spark plug(s) after every 100 operating hours. Make sure that the air gap between the center and side electrodes is correct before installing the spark plug. Use a spark plug wrench for removing and installing the spark plug(s) and a gapping tool/feeler gauge to check and adjust the air gap. Install a new spark plug(s) if necessary. 10.
3. Check the gap between the center and side electrodes (Fig. 43). Bend the side electrode (Fig. 43) if the gap is not correct. 2 1 3 1 2 0.030 in. (0.76 mm) m–4384 Figure 44 m–3215 1. Filter 2.

Fuel line Figure 46 Servicing the Spark Arrester Inspect the spark arrester every 50 hours for damage, such as holes in the screen, and for buildup on the screen. If it is damaged, replace it with a new spark arrester. If it is dirty, remove it and clean the screen with a wire brush and/or soak it in solvent. Greasing the Front Castor Pivots Lubricate the front castor pivots once a year. 1.
Servicing the Hydraulic System 3. Grease the fittings on the push arms (Fig. 47). Checking the Hydraulic Fluid Check the hydraulic fluid level before engine is first started. Check the hydraulic fluid level after first 8 operating hours. Check the hydraulic fluid level after every 25 operating hours. Fluid Type: Mobil 1 15W-50 synthetic motor oil or equivalent synthetic oil. Important Use the oil specified or equivalent. Other fluids could cause system damage. Hydraulic System Oil Capacity: 67 oz.
Warning Hydraulic fluid escaping under pressure can penetrate skin and cause injury. • If hydraulic fluid is injected into the skin it must be surgically removed within a few hours by a doctor familiar with this type of injury. Gangrene may result if this is not done. • Keep body and hands away from pin hole leaks or nozzles that eject high pressure hydraulic fluid. • Use cardboard or paper to find hydraulic leaks.
Bleeding the Hydraulic System Adjusting the Motion Controls The traction system is self bleeding; however, it may be necessary to bleed the system if the fluid is changed or after work is performed on the system. Adjusting the Handle Neutral If the motion control levers do not align, or move easily into the console notch, an adjustment is required. Adjust each lever, spring, and rod separately. 1. Raise the rear of the machine so that the wheels are off of the ground and support it with jack stands. 2.
Adjusting the Hydraulic Pump Neutral Warning Note: Adjust the handle neutral first. That has to be correct before the following adjustment can be made. Electrical system will not perform proper safety shut off with jumper wire installed. Danger • Remove jumper wire from wire harness connector and plug connector into seat switch when adjustment is completed. • Never operate this unit with jumper installed and seat switch bypassed.
Checking the Wheel Hub Slotted Nut 5. Place 2 thick blocks (1-1/2 in. [38 mm]) under the rear left and right lower edge of the mower. Place 1 block (2-1/4 in. [57 mm]) under the front center lower edge of the mower. Lower the mower to the 2 in. (51 mm) height-of-cut position (Fig. 55). Check after every 500 operating hours. The slotted nut needs to be torqued to 125 ft.-lb. (170 N⋅m). 1. Stop the engine, set the parking brake, remove the key, and disconnect the spark plug wire(s) from the spark plug(s).
Replacing the Deck Belt Note: When properly adjusted, the front blade tip will be slightly lower than the rear blade tip; refer to Checking for Bent Blades, page 28, to measure. Squealing when the belt is rotating, blades slipping when cutting grass, frayed belt edges, burn marks, and cracks are signs of a worn deck belt. Replace the deck belt if any of these conditions are evident. 10. Recheck that the blocks just fit just under the mower and that the tension on all four chains is approximately equal.
3. Remove the PTO drive belt from the rear idler arm and front idler pulley assembly. Remove the PTO drive belt (Fig. 58). 4. Place the new drive belt over the clutch, around the rear idler pulley, installed into the rear idler arm assembly, installed into the front idler pulley assembly, and onto the top center pulley (Fig. 58). 2 Important Check the amount of twist in the belt between the pulleys. Make sure that it is only what is specified in Figure 58. 1 5.
