MAINTENANCE Anti-scalp rollers can be set in three positions. • Upper position 1" to 2-1/2" grass • Middle position 2-1/2" to 4" grass • Lower position 4" to 5" grass The rollers must be approximately 1/4" from ground. Do not adjust the rollers to support the deck. ZT-3100 Powertrain Regular external maintenance of the ZT-3100 Powertrain™ should include the following: 1. Check oil level in expansion tanks. When the engine is cold, the tanks should be at the FULL COLD level. 2. Inspect the vehicle drive belt, idler pulley(s), and idler spring(s). Insure that no belt slippage can occur. Slippage can cause low input speed to the transmission. 3. Inspect the transmission cooling fan for broken or bent blades. Remove any obstructions such as grass clippings, leaves or dirt. 4. Inspect the park brake and vehicle linkage to insure proper action and adjustment of the parking. 5. Inspect the vehicle control linkage to the directional control arm on the transaxle. Also, make sure the control arm is securely fastened to the trunnion arm of the transaxle. 6. Inspect the bypass mechanism on the transaxle and unit linkage to make sure it rotates and releases fully. Cleaning Regular cleaning and washing, especially under the mower deck, will increase the machine's lifespan. Make it a habit to clean the machine directly after use (after it is cooled), before the dirt sticks. Do not spray water on the top of the mower deck. Use compressed air to clean the top side of mower deck. Regularly clean deck and underside of the deck with normal water pressure. Do not use a high pressure washer or steam cleaner. Avoid spraying engine and electrical components with water. Do not rinse hot surfaces with cold water. Let unit cool before washing. CAUTION! Always wear eye protection when cleaning and washing. Hardware Check daily. Inspect the entire machine for loose or missing hardware. IMPORTANT INFORMATION Any servicing dealer attempting a warranty repair must have prior approval before conducting maintenance of a Hydro-Gear® product, unless the servicing dealer is a current Authorized Hydro-Gear Service Center. 27
