The mower deck is disengaged. 2. The steering controls are in the outer, locked neutral position. 3. The parking brake is on. Make daily inspections to ensure that the safety system works by attempting to start the engine when one of the conditions is not met. Change the conditions and try again.
MAINTENANCE Tire Pressures All tires should be at 15 psi / 103 kPa / 1 bar. 8011-564 Check tire pressures Anti-Scalp Rollers Anti-scalp rollers are properly adjusted when they are just slightly off of the ground when the deck is at the desired cutting height in the operating position. Antiscalp rollers then keep the deck in the proper position to help prevent scalping in most terrain conditions. IMPORTANT INFORMATION Adjust anti-scalp rollers with the mower on a flat level surface.
MAINTENANCE V-belts Check every 100 hours of operation. Check for severe cracking and large nicks. NOTE: The belt will show some small cracks in normal 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 parking brake. 2. Lower the deck into the lowest cutting position. 3. Remove bolts from belt shields and remove shields. 4.
MAINTENANCE Cutting Blades To attain the best mowing effect, it is important that blades are well sharpened and not damaged. Replace blades that have been bent or cracked when hitting obstacles. Let the service workshop decide whether a blade with large nicks can be repaired/ground or must be replaced. Balance the blades after sharpening. Check the blade mounts. WARNING! Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling.
MAINTENANCE Adjusting the Mower Deck Leveling deck Adjust the deck while the mower is on a level surface. Make sure the tires are inflated to the correct pressure. See Technical Data under Transmission. If tires are under or over inflated, the deck cannot be properly adjusted. The deck should be adjusted slightly higher in the rear. NOTE: To insure accuracy of leveling procedure, mower deck drive belt must be installed prior to leveling deck. 1. Wear heavy gloves.
