When the engine is running, any attempt by the operator to leave the seat without first setting the parking brake will shut off the engine. 2. Move the steering controls to the neutral position (N). 8058-020 Parking brake released 3. Set retaining pin into selected cutting height and secure the opposite side with a cotter hairpin.
OPERATION 6. Engage the mower deck by pulling out the blade switch. 7. Move throttle control to full throttle. The machine’s speed and direction are continuously variable using the two steering controls. When both controls are in the neutral position, the machine stands still. By moving both controls an equal amount forward or backward, the machine moves in a straight line forward or backward respectively.
OPERATION Mowing Tips • • • • • • • • Observe and flag rocks and other fixed objects to avoid collisions. Begin with a high cutting height and reduce it until the desired mowing result is attained. The average lawn should be cut to 2½" (64 mm) during the cool season and over 3" (76 mm) during the hot months. For healthier and better looking lawns, mow often after moderate growth. For best cutting performance, grass over 6" (15 cm) in height should be mowed twice.
OPERATION Stopping the Engine Allow the engine to idle a minute in order to attain normal operating temperature before stopping it, if it has been worked hard. Avoid idling the engine for longer periods, as there is a risk of the spark plugs fouling. • Disengage the mower deck by depressing the blade switch. 8052-001 Disengage the mower deck and move throttle to minimum • Raise the mower deck by pressing the button on the lever and pulling it backward to the transport position.

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. 8058-079 Check tire pressures Parking Brake Visually check that no damage is found on the lever, cables, or switch belonging to the parking brake. Perform a standstill test and check that there is sufficient braking action. To adjust the parking brake, contact the Husqvarna service workshop. IMPORTANT INFORMATION The machine must be absolutely standing still when applying the parking brake.
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 Pump Belt Replacing pump belt Park the mower on a level surface. Engage the parking brake. Belt removal 1. Remove the deck belt (see Deck Belt Removal in this section of the manual). 2. Create slack in the belt by removing the spring on the pump idler arm. 3. The belt should now be able to be removed from the engine pulley and pump pulleys. Belt installation 1. Wrap the belt around the pulley 2. Route the belt around the inside of the idler pulley. 3. Wrap the belt around the engine pulley. 4.
maintenance Cutting Blades In order to attain the best mowing effect, it is important that the blades are well sharpened and not damaged. Bent or cracked blades or blades with large nicks should be replaced. IMPORTANT INFORMATION The sharpening of blades should be carried out by an authorized service workshop. Damaged blades should be replaced when hitting obstacles that result in a breakdown. Let the service workshop decide whether the blade can be repaired/ ground or must be replaced.
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.
maintenance 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. IMPORTANT INFORMATION Adjust anti-scalp rollers with the mower on a flat level surface.
maintenance 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 8050-832 12/12 Every year 1/52 Every Week 1/365 Every day Lubricate with grease gun Oil change Filter change Lubricate with oil can Level check * Change transmission filter 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 a high grade molybdenum disulphide grease. For daily use, the machine should be lubricated twice weekly.
LUBRICATION Front Wheel Mount Lubricate with a grease gun, one zerk for each wheel mount, until the grease is forced out. Use only good quality bearing grease. Grease from well-known brand names (petrochemical companies) usually maintains a good quality. Front Wheel Bearings Lubricate with a grease gun, one zerk for each set of wheel bearings, until the grease is forced out. Use only good quality bearing grease.
LUBRICATION Transaxle 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 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. 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.
troubleshooting guide Problem Engine will not start Starter does not turn the engine over Engine runs rough Engine seems weak Machine vibrates Cause • Blade switch is engaged. • Steering controls are not locked in the neutral position • Parking brake is not activated • Battery is dead • Contamination in the carburetor or fuel line.
troubleshooting guide Problem Engine overheats Battery not charging The machine moves slowly, unevenly, or not at all Mower deck not engaging Transaxle leaks oil Uneven mowing results 50 Cause • Clogged air intake or cooling fins • Engine overloaded • Poor ventilation around engine • Defective engine speed regulator • Too little or no oil in the engine • Contamination in the carburetor or fuel line.
STORAGE Winter Storage At the end of the mowing season, the machine should be readied for storage (or if it will not be in use for longer than 30 days). Fuel allowed to stand for long periods of time (30 days or more) can leave sticky residues that can plug the carburetor and disrupt engine function. Fuel stabilizers are an acceptable option as regards to the sticky residues that can occur during storage. Add stabilizer to the fuel in the tank or in the storage container.
