MAINTENANCE Caster Wheels Check at 200 hour intervals. Check that wheels turn freely. If wheels do not turn freely take the unit to the dealer for service. Foam filled tires or solid tires will void the warranty. Removal and installation Remove nut and caster bolt. Pull the wheel out of the yoke and take care of the spacers. Install in reverse order. Tighten caster bolt. NOTE: The belt will show some small cracks in usual operation. The belts are not adjustable. Replace belts if they begin to slip from wear. Deck Belt Removal 1. Park on a level surface. Apply park brake. 2. Lower the deck into the lowest cutting position. 3. Remove bolts from belt shields and remove shields. 4. Remove any dirt or grass that may have accumulated around the cutter housings and entire deck surface. 5. Loosen the nut securing the belt guide. Note the position of the belt guide for reinstallation. Anti-scalp Rollers Anti-scalp rollers are correctly adjusted when they are slightly off of the ground when the deck is at the desired cutting height in the operating position. Anti-scalp rollers keep the deck in the proper position to help prevent scalping in most terrain conditions. The anti-scalp rollers can be set in three positions: • Upper position 1-1/2" to 2-1/2" grass • Middle position 2-1/2" to 4" grass • Lower position 4" to 6" grass. The rollers must be approximately 1/4" from the ground. V-belts Check at 100 hour intervals of operation. Check for severe cracking and large nicks. 6. Push inward on the idler arm to release the tension on the belt. 7. Carefully lift the belt over the top of the cutter housing pulleys and remove belt from the deck. Deck Belt Installation NOTE: For ease in installing the deck belt, refer to the routing decal on the top of the deck. 1. Wind the deck belt around the electric clutch pulley located on the engine shaft. 2. Route the belt forward and up onto the deck. 3. Position the belt around spring loaded idler pulley. 4. Wind the belt around the stationary idler pulley and the mandrel housings. 5. Push inward on the idler arm and carefully put the belt over the stationary idler pulley. When the belt is correctly routed, slowly release the idler arm to tension the belt. 6. Double check the belt routing to make sure it matches the routing decal, and the belt does not have twists. 7. Set the loosened belt guide into the idler arm hole and tighten the pulley bolt. 8. Replace belt shields on both mandrel housings and secure with fasteners. 25
