The engine can only be started when: • The mower deck is disengaged. • The steering controls are in the outer, locked neutral position. • 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 Deck Belt Deck Belt Removal Park on a level surface. Apply park brake. Lower the deck into the lowest cutting position. 1. Remove foot plate and belt shields. 2. Using a ratchet or breaker bar with a 9/16" socket on the spring idler bolt, relieve the tension on the belt. 3. Remove any dirt or grass that may have accumulated around the cutter housings and entire deck surface. 4. Carefully roll the belt over the top of the cutter housing pulleys. 5.
MAINTENANCE Pump Belt The belts are not adjustable. Replace belts if they begin to slip from wear. Replacing Pump Belt Park the mower on a level surface. Engage the parking brake. Belt Removal From the top side of the deck: 1. Remove the deck belt (see Deck Belt Removal in this section of the manual). 2. Tilt seat forward to access fan covers. Remove both fan covers. From the underside of the mower: 3. Remove clutch stop to access the belt. 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. Blade Replacement WARNING! Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling. 1.
MAINTENANCE Adjusting the Mower Deck WARNING! Check the tire pressure before adjustment of the mower deck. See Tire Pressures in Maintenance section. Faulty mower deck adjustments will cause an uneven mowing result. 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 / Transmission. If tires are under or over inflated, you cannot properly adjust your deck. Four slots control the height and pitch of the mower deck.
MAINTENANCE Anti-scalp Rollers Anti-scalp rollers keep the deck in the proper position to help prevent scalping in most terrain conditions. Do not adjust the rollers to support the deck. 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. IMPORTANT INFORMATION Adjust anti-scalp rollers with the mower on a flat level surface.
MAINTENANCE ZT-3400 Powertrain Cleaning Regular cleaning and washing, especially under the mower deck, will increase the machine’s life-span. 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.
LUBRICATION Lubrication Schedule 8065-095 12/12 Every year Lubricate with grease gun Filter change Oil change Level check 1/52 Every Week 1/365 Every day * Change hydraulic drive filters. p Change engine oil every 50 hours. General Remove the ignition key to prevent unintentional movements during lubrication. When lubricating with an oil can, it must be filled with engine oil. When lubricating with grease, unless otherwise stated, use high grade molybdenum disulphide grease.
LUBRICATION Engine Oil Change NOTE: Change the engine oil when the engine is warm. Refer to the engine owner’s manual for the correct replacement oil and filter change recommendations. 1. Park on a level surface. Apply parking brake. 2. Clean the dirt and debris from the area around the oil fill cap. 3. Remove the cap/dipstick. 4. Locate the drain hose at the left rear of the engine. Place an adequately sized container under the end of the drain hose and remove the oil drain plug. 5.
LUBRICATION Deck Spindle Lower the cutting deck completely. If a grease gun without rubber hose is used, the foot plate must be removed to access the center spindle. Lubricate with a grease gun, 2-3 strokes per spindle.
LUBRICATION Transaxle (Transmission) Fluid Change This transaxle is designed with an external filter for ease of maintenance. To ensure constant fluid quality levels and longer life, an oil filter change interval of every 200 hours is recommended. The following procedure is performed with the transaxles installed in the mower and the mower on level ground. Apply the pump release valve for each transaxle and set the parking brake. 1. Remove the three ¼" filter guard screws and filter guard.
LUBRICATION Transmission Purging Due to the effects air has on efficiency in hydrostatic drive applications, it is critical to purge the system. These purge procedures should be implemented any time a hydrostatic system has been opened to facilitate maintenance or any additional oil has been added to the system. Resulting symptoms in hydrostatic systems may be: • Noisy operation. • Lack of power or drive after short term operation. • High operation temperature and excessive expansion of oil.
