SAFETY Safety Instructions • Watch for traffic when operating near or crossing roadways. • Use extra care when loading or unloading the machine into a trailer or truck. • Always wear eye protection when operating machine. • Wear proper Personal Protective Equipment (PPE) while operating this machine, including (at a minimum) sturdy footwear, eye protection, and hearing protection. Do not mow in shorts and/or footwear with open toes.
SAFETY Slope Operation Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operation on all slopes requires extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it. • Mow up and down slopes (10 degrees maximum), not across. • Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.
SAFETY • Never fill containers inside a vehicle or on a truck or trailer bed with plastic liner. Always place containers on the ground away from the vehicle when filling. • Remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, refuel such equipment with a portable container, rather than from a gasoline dispenser nozzle. • Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.
SAFETY Towing • The machine is tested and approved only with the equipment originally provided or recommended by the manufacturer. Only use approved repair parts for the machine. • The blades are sharp and can cause cuts and gashes. Wrap the blades or use protective gloves when handling them. If machine is equipped with a tow hitch, use extreme caution when towing. Never allow children or others in or on towed equipment.. Make wide turns to avoid jack-knifing.
CONTROLS This operator manual describes the Husqvarna Zero Turn Rider. The rider is fitted with a Briggs & Stratton four-stroke overhead valve engine. Transmission from the engine is made via a belt-driven hydraulic pumps. Using the left and right steering controls, the flow is regulated and thereby the direction and speed. Control Locations 3 2 4 5 1 14 5 13 6 7 8 12 9 11 10 1. 2. 3. 4. 5. Motion control levers Park brake Tracking knob Fuel tank Hydro release levers 6. 7. 8. 9. 10. 11.
CONTROLS Steering Control Levers WARNING! The machine can turn very rapidly if one steering control is moved much further forward than the other. Park Brake The machine’s speed and direction are continuously variable using the two steering controls. The steering controls can be moved forward or backward about a neutral position. Furthermore, there is a neutral position, which is locked if the steering controls are moved outward. When both controls are in the neutral position (N), the machine stands still.
CONTROLS Throttle Control Service Minder The throttle control regulates the engine speed and thereby the rate of rotation of the blades, assuming the blade switch is pulled out, see Engaging the Mower Deck. To increase or decrease the engine speed, the control is moved forward or back respectively. Avoid idling the engine for long periods, as there is a risk of fouling the spark plugs. USE FULL THROTTLE WHEN MOWING, for best mower performance and battery charging.
CONTROLS Fuses Cutting Height Lever Fuses are located on the left hand side of the machine and are accessed by tilting the seat forward. Fuses are flat pin fuses type as used in automobiles. The 20 A is the primary fuse. The 7.5 A is for the mower deck coupling. The desired cutting height is set with the height pin.The cutting height pedal releases the deck lift to place the deck at the selected height.
CONTROLS Fuel Tank IMPORTANT INFORMATION Experience indicates that alcohol blended fuels (called gasohol, ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel the next season.
OPERATION Before Starting Read the Safety section and following pages, if you are unfamiliar with the machine. 1. Training 2. Due to unique steering capabilities, zero turn mowers are far more maneuverable than typical riding mowers. This section should be reviewed in its entirety prior to attempting to move the mower under its own power. When first operating the mower or until becoming comfortable with controls, use a reduced throttle speed and reduced ground speed.
OPERATION Starting the Engine 1. 2. 3. 4. 5. Move the steering controls outward to the locked (outer) neutral position. 6. Move throttle control to full throttle (rabbit symbol). 7. 8. 9. Open the fuel tank valve. Press in and turn the ignition key to the start position. When the engine starts, immediately release the ignition key back to the run position. Slowly push in the choke control knob, if it was used to start a cold engine. Sit on the seat.
OPERATION Running 1. Release the park brake by moving the lever downward. NOTE: The mower is equipped with an operator presence system. When the engine is running, any attempt by the operator to leave the seat without first setting the park brake will shut off the engine. WARNING! Engine exhaust and certain vehicle components contain or emit chemicals considered to cause cancer, birth defects or other reproductive system damage.
OPERATION 4. 5. 6. 7. Mowing Tips Raise the mower deck by pressing the foot pedal forward to the transport position. • 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.
OPERATION Weak Battery Moving Machine By Hand If the battery is too weak to start the engine, it should be recharged. (See Battery in the Maintenance section.) If jumper cables are used for emergency starting, follow this procedure: When pushing or pulling the mower, engage the IZT (Integrated Zeroturn Transaxle) bypass linkages. The release levers are located on each side of the rear of the unit below the rear engine plate. 1. Raise the deck to the highest (transport) position. 2.
MAINTENANCE Maintenance Schedule The following is a list of maintenance procedures that must be performed on the machine. For those points not described in this manual, visit an authorized service workshop. An annual service carried out by an authorized service workshop is recommended to maintain your machine in the best possible condition and to ensure safe operation. Read General Maintenance in the Safety section.
MAINTENANCE Daily MAINTENANCE Before After At least once each year Check/adjust throttle cable Check the condition of belts, belt pulleys Change the engine oil 1) Replace the engine oil filter Clean/replace the spark plugs Replace the fuel filter Replace the paper air filter 2) Check the caster wheels (every 200 hours) Replace the air cleaner’s foam pre-filter 2) ● Check the hydraulic oil in the oil tank Change the hydraulic oil (every 300 hours) Replace the hydraulic oil filter (every 300 hours) ● ■
MAINTENANCE Battery Your mower is equipped with a maintenance free battery and does not need servicing. However, periodic charging of the battery with an automotive type battery charger will extend its life. • Keep battery and terminals clean. • Keep battery bolts tight. • See chart for charging times. STANDARD STATE BATTERY OF CHARGE APPROXIMATE BATTERY CHARGING TIME* TO FULL CHARGE AT 80OF / 27OC Maximum Rate at: 50 Amps 30 Amps 20 Amps 10 Amps 12.6V 100% - FULL CHARGE - 12.4V 75% 20 min.
MAINTENANCE Safety System Park Brake The 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 park brake is on. Visually check that no damage is found on the lever, links, or switch belonging to the park brake. Perform a standstill test and check that there is sufficient braking action.
MAINTENANCE Caster Wheels V-belts Check every 200 hours. Check that wheels rotate freely. If wheels do not rotate freely take the unit to your dealer for service. Foam filled tires or solid tires will void the warranty. Removal and installation Remove nut and caster bolt. Pull the wheel out of the yoke and take care of the spacers. Install in reverse order. Tighten caster bolt. Check every 100 hours of operation. Check for severe cracking and large nicks.
MAINTENANCE Pump Belt 3. 4. 5. 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 park 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. 6. 7. 8. Place the belt over the right and left idler pulleys. Place the belt on the engine pulley.
MAINTENANCE 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. 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.
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 3-4 strokes with a grease gun on each set of wheel bearings. Front Wheel Bearings Lubricate 3-4 strokes with a grease gun on each set of wheel bearings.
LUBRICATION Engine oil change Transaxle (Transmission) Fluid 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. 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.
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 for maintenance or if 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 Problem / Cause Engine will not start Engine overheats Blade switch is engaged Clogged air intake or cooling fins Steering controls are not locked in the neutral position Engine overloaded Park brake is not activated Poor ventilation around engine Battery is dead Defective engine speed regulator Contamination in the carburetor or fuel line Too little or no oil in the engine Fuel supply shutoff valve is closed Contamination in the fuel line.
STORAGE Winter Storage To ready the machine for storage: 1. Thoroughly clean the machine, especially under the mower deck. Touch up damage to the paint and spray a thin layer of oil on the underside of the mower deck to avoid corrosion. 2. Inspect the machine for worn or damaged parts and tighten any nuts or screws that may have become loose. 3. Change the engine oil; dispose of properly. 4. Empty the fuel tanks or add a fuel stabilizer.
