SERVICE AND MAINTENANCE Sharpening or Replacing the Blade Note: It may be easier to change the blade by first removing the deck from beneath the tractor, (refer to Cutting Deck Removal earlier in this section) then gently flip the deck over to expose its underside. It is possible to change the blade, however, with the deck still attached to the tractor. If attempting to change the blade with the deck still installed on the tractor, first move the deck lift lever to its highest (#5) position. 1. Remove the mulch plug, deck chute or bagging chute, if equipped, exposing the deck chute opening. 2. Using a block of wood or 2 x 4, insert it into the deck opening and rotate the blade around until it wedges the wood between the deck opening and the cutting blade, as shown in Figure 21. 3. Remove the hex screw (a) and the blade bell support (b) which holds the blade (c) and the blade adapter (d) to the deck motor. See Figure 22. Figure 21 (d) 4. Remove blade (c) and adapter (d) from the deck motor spindle See Figure 22. 5. To properly sharpen the cutting blade, remove equal amounts of metal from both ends of the blade along the cutting edges, parallel to the trailing edge, at a 25°- to 30° angle. Always grind each cutting blade edge equally to maintain proper blade balance. See Figure 23. 6. Test the blade's balance using a blade balancer. Grind metal from the heavy side until it balances evenly. (b) (c) (a) Figure 22 Figure 23 WARNING A poorly balanced blade will cause excessive vibration, may damage the tractor and/or result in personal injury. Note: When replacing the blade, be sure to install the blade with the side of the blade marked ''Bottom'' (or with a part number stamped in it) facing the ground when the tractor is in the operating position. 7. Reinstall blade when properly sharpened. Torque to 450-600 in-lbs (50.9-67.8 N-m). Off-Season Storage Storing the Tractor • Allow the machine to cool in an open area before storing. • Do not park the tractor near any flammable materials (wood, cloth or chemicals) or any open flames or other potential source of ignition (furnace, water heater or any other type of heater). • Remove all combustible materials from the tractor before storing. Empty cargo boxes, grass catchers or containers. Removing The Tractor From Storage 1. Fully charge the battery and inflate the tires to the recommended pressures. 2. Drive the tractor without a load to make certain all the tractor systems are functioning properly. Battery Storage 1. The battery should be stored with a full charge. A discharged battery can freeze faster than a charged battery in cold temperatures. 2. The battery charger should remain connected to the charging port on the tractor when not in use. 3. If keeping the charger connected during off-season storage is not possible, the battery should be fully charged once every month. Note: It will take approximately 4 hours to fully charge the battery. Leaving the battery connected to the charger for more than 4 hours will not damage the battery. 4. Battery should not be kept in a discharged state. Permanent damage to the battery can occur. 5. Fully recharge the battery before returning to service. Battery Disposal Disposing of Damaged or Worn-Out Battery WARNING • The following toxic and corrosive material is used in this battery: LITHIUM-ION, a toxic material. • Do not use broken or cracked batteries, even if there is no leakage. Replace damaged or worn-out batteries with new batteries. DO NOT ATTEMPT TO REPAIR BATTERIES! Repair attempts may result in severe personal injury, due to explosion or electrical shock. To avoid personal injury and damage to the environment: • Do not attempt to remove or destroy any of the battery components. Do not open or mutilate the battery. If a leak develops, released electrolytes are corrosive and toxic. Do not get the solution in your eyes or on your skin, and do not swallow it. • Do not dispose of the battery in the regular household trash. • Do not dispose of the battery in a fire. The cell may explode. • Do not dispose of the battery where it will become part of any waste landfill or municipal solid waste stream. • Contact your local authorized service dealer for proper battery recycling. 15
