Safety System This machine is equipped with a safety system that prevents starting or driving under the following conditions. 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.
Deck Belt Deck Belt Removal Park on a level surface. Apply park brake.Lower the deck into the lowest cutting position. Remove foot plate and belt shields. Using a ratchet or breaker bar with a on the spring idler bolt, relieve the tension on the belt.
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: Remove the deck belt (see in this section of the manual).
Install and tighten blade bolt securely. Torque blade bolt to 45-55 ft-lbs (60-75 Nm). IMPORTANT INFORMATION Special blade bolt is heat treated. Replace with a Husqvarna bolt if required. Do not use lower grade hardware than specified. WARNING! Before performing any service or adjustment checklist: 1.
Adjusting the Mower Deck 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.
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. Anti- scalp rollers then keep the deck in the proper position to help prevent scalping in most terrain conditions.
Caster Wheels Check every 200 hours. Check that wheels rotate freely. IMPORTANT INFORMATION DO NOT add any type of tire liner or foam fill material to the tires. Excessive loads created by foam tires wil caues premature failures. Use only O.E.M. specified tires. Removal and Installation Remove nut and caster bolt.
Lubrication Schedule 12/12 Every year 1/52 Every Week 1/365 Every day Change hydraulic drive filters. p See Engine Manufacturer's manual General Remove the ignition key to prevent unintentional movements during lubrication. When lubricating with an oil can, it must be filled with engine oil.
lUbRICaTION Wheel and Deck Zerks Use only good quality bearing grease. Grease from well-known brand names (petrochemical companies, etc.) usually maintains a good quality. Front Wheel Mount Lubricate with a grease gun until the grease is forced out. Front Wheel Bearings Lubricate 3-4 strokes with a grease gun on each set of wheel bearings.
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.
Purging Procedures 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.
