Gasoline is extremely flammable and the vapors are explosive. • Extinguish all cigarettes, cigars, pipes, and other sources of ignition. • Use only approved gasoline containers. • Never remove gas cap or add fuel with the engine running. Allow engine to cool before refueling. • Never fuel the machine indoors. • Never store the machine or fuel container where there is an open flame, spark or pilot light such as on a water heater or other appliance. • Before you begin refueling, minimize the risk of static electricity by touching a metal surface. • 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. • Never overfill fuel tank. Replace gas cap and tighten securely. 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. 8 SAFETY • 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. Do not use a nozzle lock-open device. • If fuel is spilled on clothing, change clothing immediately. • Do not start the engine near spilled fuel. • Never use gasoline as a cleaning agent. • If leaks arise in fuel system, the engine must not be started until problem has been resolved. • Check the fuel level before each use and leave space for the fuel to expand, as the heat from the engine and the sun may otherwise cause the fuel to expand and overflow. • The blades are sharp and can cause cuts and gashes. Wrap the blades or use protective gloves when handling them. • Never work with the starter circuit if there is spilled fuel. • Ensure that the fuel filler cap is mounted tightly and no flammable substances are stored in an open vessel. • Sparking can occur when working with the battery and the heavy cables of the starter circuit. This can cause battery explosion, fire or eye injury. Sparking will not occur after the grounding cable (normally negative, black) is removed from the battery. • Disconnect the grounding cable from the battery first and reconnect it last. • Do not make a bridge short circuit across the starter relay to run the starter. • Be very careful when handling battery acid. Acid on skin can cause serious corrosive burns. If you spill battery acid on your skin, rinse immediately with water. • Acid in the eyes can cause blindness, contact a doctor immediately. • Be careful when servicing the battery. Explosive gases form in the battery. Never perform maintenance on the battery when smoking or near open flames or sparks. The battery can explode and cause serious injury or damage. • 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. • Check the park brake’s functionality regularly. Adjust and service as necessary. • The mulch blades should only be used in familiar areas when higher quality mowing is desired. • Regularly clean deck and underside of deck, avoid spraying engine and electrical components with water. CAUTION! Use protective glasses for maintenance work. General Maintenance • Never use the machine indoors or in spaces lacking proper ventilation. The exhaust fumes contain carbon monoxide, an odorless and poisonous lethal gas. • Make sure that the equipment is in good condition and that all nuts and bolts, especially those fastening the blade attachments, are properly tightened and torqued. • Maintain or replace safety and instruction labels as necessary. • Never interfere with the intended function of a safety device or reduce the protection provided by a safety device. Check their proper operation regularly. NEVER operate a machine with a safety device that does not function properly. WARNING! The engine must not be started when the driver’s floor plate or any protective plate for the mower deck’s drive belt is removed. WARNING! The battery contains lead and lead compounds, chemicals that are considered to cause cancer, birth defects, and other reproductive system damage. Wash your hands after handling the battery. • Check grass catcher components and the discharge guard frequently and replace with manufacturer’s recommended parts when necessary. • Do not change the settings of governors and avoid running the engine with overly high engine speeds. If you run the engine too fast, machine components could be damaged. • To reduce the risk of fire, keep machine free of grass, leaves or other debris buildup.

Transmission from the engine is made via a belt-driven hydraulic pumps. Using the left and right steering controls, the flow is regulates the direction and speed. Control Locations 3 2 4 5 1 5 6 7 13 8 9 10 11 12 1. Steering/Brake levers 8. Choke control 2. Tracking adjustment, left side 9. Throttle control 3. Deck lift 10. Service meter 4. Fuses 11. Ignition switch 5. Bypass linkages 12. Blade switch 6. Fuel shut off valve 13. Seat adjustment lever 7. Fuel tank 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. By moving both controls an equal amount forward or backward, the machine moves in a straight line forward or backward respectively. In order, for example, to turn right while moving forward, move the right control towards the neutral position. The rotation of the right wheel is reduced and the machine turns to the right. Zero turn can be achieved by moving one control backward (behind the neutral position) and carefully moving the other steering control forward from its neutral position. The rotation direction when zero turning is determined by which steering control is moved backward behind the neutral position. If the left steering control is pulled backward, the machine turns to the left. Use extra care when using this maneuver. If the steering controls are in uneven positions when standing still or do not fit in the slots for moving the controls outward, they can be adjusted. The park brake is integrated with the steering control levers. Move the levers outward from the neutral position to engage the park brake. To release the park brake, rotate both steering control levers inwards to the neutral position. Do not attempt to operate the unit without both levers being inwards out of the engaged position or machine components could be damaged. IMPORTANT INFORMATION The machine must stand absolutely still when applying the park brake. Always set the park brake before dismounting. Release the park brake before moving the mower. Ignition Switch Forward Neutral Park Brake Reverse The ignition switch is placed on the control panel and is used to start and stop the engine. 12 CONTROLS Throttle Control Service Meter The throttle control regulates the engine speed and the rate of rotation of the blades, assuming the blade switch is pulled out. See Blade Switch. 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. The service meter displays the total number of hours the engine has run and indicates when the engine and mower need servicing. After every 50 hours of operation, an oil can icon will appear and stay on for two hours, before an automatic reset occurs. To manually reset the meter, turn the key off and on five times at one second intervals. To service the engine and mower, see the Service Journal of this manual. Note: The service meter operates (clocks hours) only when the engine is running. Be sure to turn the key off when the unit is not in use, to prevent meter hours from accumulating. Blade Switch Choke Control To engage the mower deck, pull the knob out; mower blades are disengaged when the knob is pressed down. The choke control is used for cold starts to provide the engine with a richer fuel mixture. For cold starts the control should be pulled up. 13 CONTROLS Fuse Cutting Height Lever The 20 amp primary fuse is located on the left hand side of the machine. It is accessed by tilting the seat forward. The fuse is a flat pin type used in automobiles. To set the deck cutting height, pull the cutting height lever inwards and move it to the desired height notch. IMPORTANT INFORMATION Always raise the deck to the highest position for transport. Seat Adjustment Lever IMPORTANT INFORMATION To obtain an even cutting height, it is important that the air pressure in all tires is 15 psi / 103 kPa / 1 bar. Bypass Linkages The seat can be adjusted lengthways. When making adjustments, the lever under the right side of the seat is pulled up, after which the seat can be moved backward or forward. Fuel Shut Off Valve Transaxle bypass linkages must be engaged when pushing or pulling the mower. The release levers are located on each side of the rear of the unit below the rear engine guard. See Moving Machine By Hand in the Operation section. WARNING! Bypass linkages are located close to the muffler. To prevent burns, the engine should be shut off and allowed to cool before the bypass linkage levers are handled. The fuel shut off valve is located at the right rear of the seat. The valve is off when the handle tab is turned perpendicular to the fuel line. 14 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. See Storage for additional information. Never use engine or carburetor cleaners in the fuel tank or permanent damage may occur. Tracking WARNING! Gasoline is highly flammable. Observe caution and fill the tank outdoors (see the safety instruction). WARNING! The engine and the exhaust system, become very hot during operation. There is a risk for burns if touched. Allow engine and exhaust system to cool before refueling. WARNING! Fill to bottom of filler neck. Do not overfill. Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame. If the mower is not tracking straight, check the air pressure in both rear tires. Recommended air pressure for the rear tires is 15 psi (1 bar). 1. Tracking adjustments are made using the tracking bolts. The tracking bolts act as limiting devices for the motion control levers when in the full-forward position. 2. For preliminary tracking adjustment, move unit to an open, unobstructed area such as an empty parking lot or open field. 3. Using a ½" wrench, back the tracking bolts out until flush with nut. 4. Test operate unit by driving it at full throttle and the full forward position on both motion control levers. Gradually turn in the tracking bolt on the right hand side until the unit noticeably starts drifting right. 5. Drive forward at full throttle with both motion control levers in the full forward position. Gradually turn in the left tracking bolt until unit tracks straight. Read the safety instructions before refueling. The machine has one fuel tank, just behind the console. The tank capacity is 3½ gallons (13.25 litres). Regularly check the gas cap gasket for damage and keep the cap properly tightened. The engine will run on a minimum of 87-octane unleaded gasoline (no oil mix). Environmentally adapted alkylate gasoline can be used. See also Technical Data concerning ethanol fuel. Methanol fuel is not allowed. Do not use E85 alcohol based fuel. Damage to engine and components may occur. When operating in temperatures below 32° F. (0° C.), use fresh, clean winter grade gasoline to insure good cold weather starting. 15 OPERATION Before Starting Read the Safety section and following pages, if you are unfamiliar with the machine. 1. Read the sections on Safety and Controls before starting the machine. 2. Perform the daily maintenance before starting (see Maintenance Schedule in the Maintenance section). 3. Check that there is sufficient fuel in the fuel tank. 4. Adjust the seat to the desired position. The following conditions must be fulfilled before the engine can be started: • The blade switch must be pressed down into the disengaged position. • Both steering / park brake controls must be in the locked (outer) position. Training 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. DO NOT move control levers to the furthest forward or reverse positions during initial operation. First time users should become familiar with the mower’s movement on a hard surface, such as concrete or blacktop PRIOR to attempting to operate on turf. Until the operator becomes comfortable with the mower controls and zero turning capability, overly aggressive maneuvers may damage turf. WARNING! Engine exhaust and certain vehicle components contain or emit chemicals considered to cause cancer, birth defects or other reproductive system damage. The engine exhaust contains carbon monoxide, which is a odorless, colorless, poisonous gas. Do not use the machine in enclosed spaces. Steering To move forward and backward The direction and speed of the mower’s movements are effected by the movement of the control lever(s) on each side of mower. The left control lever controls the left wheel. The right control lever controls the right wheel. First time users should push the mower (see Moving the Machine By Hand in the Operation section) to an open, flat area without other people, vehicles or obstacles nearby. To move the unit under its own power, the operator must sit in the seat and start the engine (see Before Starting in the Operation section). Adjust the engine speed to idle and disengage the park brake by moving the steering control levers inward. Do not engage the blades. As long as the control levers have not been moved forward or backwards, the mower will not move. Slowly move both control levers slightly forward. This will allow the mower to move forward in a straight line. Pull the control levers back to the neutral position and the mower should stop moving. Pull back slightly on control levers, allowing the mower to move backwards. Push the control levers forward to the neutral position and mower should stop moving. To turn to the right While moving in a forward direction, pull the right lever back towards the neutral position while maintaining the position of the left lever, this will slow the rotation of the right wheel and cause the machine to turn in that direction. To turn to the left While moving in a forward direction pull the left lever back towards the neutral position while maintaining the position of the right lever, this will slow the rotation of the left wheel and cause the machine to turn in that direction. To zero turn While moving in a forward direction, first pull both control levers back until the mower stops or slows dramatically. Then by alternating one lever slightly to the forward position and the other in the reverse position, complete the turn. Starting the Engine 16 1. 2. Sit on the seat.

Release the park brake by pulling the steering / park brake controls inwards to the neutral position. 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. Lower the mower deck to the desired cutting height. 3. 4. Move throttle control to full throttle (rabbit symbol). Engage the mower deck by pulling the blade switch up. 5. Rotate control levers inward and slowly move both control levers slightly forward to move forward in a straight line. Move the throttle to the middle position. If the engine is cold, the choke control should be pulled up. 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. Push the choke control in gradually when the engine has started. WARNING! Make sure that no one is near mower when engaging blade switch. Make sure the work area is free from objects that could be thrown by the rotating blades. IMPORTANT INFORMATION Do not run the starter for more than 5 seconds each time. If the engine does not start, wait approximately 10 seconds before retrying. WARNING! Do not drive up or down hills with slopes greater than 10 degrees. Do not drive across slopes. 17 OPERATION Stopping the Engine 1. 2. 3. 4. 5. • When mowing large areas, start by turning to the right so that clippings will discharge away from shrubs, fences, driveways, etc. After one or two rounds, mow in the opposite direction making left hand turns until finished. Move the throttle to the minimum position (tortoise symbol). Move the steering / park brake controls outward from the neutral position. Disengage the mower deck by pressing the blade switch down. • Avoid mowing wet lawns. The mowing result is poorer because the wheels sink into the soft lawn, clumps build, and grass clippings fasten under the cowling. • Hose the mower deck underside with water after each use. When cleaning, the mower deck shall be raised into the transport position. Make sure the mower is cooled and the engine is off. • Use compressed air to clean top surface of the deck. Avoid flooding water on top surface, engine and electrical components. • When the mulching kit is used, it is important that the mowing interval is frequent. Raise the mower deck to the highest position. If the engine has been worked hard, allow it to idle at least 60 seconds to attain a normal operating temperature before stopping. To prevent fouling the spark plugs, avoid idling the engine for longer periods. Turn the ignition key to the stop position. Remove key. Always remove key when leaving the mower to prevent unauthorized use. IMPORTANT INFORMATION Leaving the ignition switch in any other position than OFF will cause the battery to be discharged. Operating On Hills Read the Safety Instructions Driving on Slopes in the Safety section. • The slowest speed possible should be used before starting up or down hills. • Avoid stopping or changing speed on hills. • If stopping is absolutely necessary, pull steering controls into the neutral position and the push to the outside of the unit to engage the park brake. • To restart movement, move the steering controls back to the neutral position. • Press forward to regain forward motion. • Make all turns slowly. 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" during the cool season and over 3" during the hot months. For healthier and better looking lawns, mow often after moderate growth. For best cutting performance, grass over 6" in height should be mowed twice. Make the first cut relatively high, the second to the desired height. • The mowing result will be best with a high engine speed (blades rotate rapidly) and low speed (rider moves slowly). If the grass is not too long and dense, the driving speed can be increased without negatively affecting the mowing result. • The finest lawns are obtained by mowing often. The lawn becomes more even and the grass clippings more evenly distributed over the mown area. The total time taken is not increased as a higher operating speed can be used without poor mowing results. WARNING! Never drive the rider on terrain that slopes more than 10 degrees. Mow slopes up and down, never side to side. Avoid sudden directional changes. 18 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 EZT bypass linkages. The EZT bypass linkages are located on the rear of the frame, below the rear engine guard. 1. Raise the deck into the highest cutting position. 2. Move the steering / park brake controls inwards to the neutral position. 3. Pull the EZT bypass linkages up and out of the keyhole slots. Release the levers with the head outside the frame and held in the bypass position. Jumper Cable Use 1. Connect each end of the RED cable to the POSITIVE (+) terminal on each battery, taking care not to short against chassis. 2. Connect one end of the BLACK cable to the NEGATIVE (-) terminal of the fully charged battery. 3. Connect the other end of the BLACK cable to a good CHASSIS GROUND on the mower with the discharged battery, away from the fuel tank and battery. To remove cables, reverse order 1. Remove BLACK cable first from chassis and then from the fully charged battery. 2. Remove RED cable last from both batteries. 2 1 4. To reengage the EZT’s to drive, reverse the above procedure. Load the machine into truck or trailer by driving slowly up the ramps. DO NOT LIFT! The machine is not intended to be lifted by hand. WARNING! Bypass linkages are located close to the muffler. To prevent burns, the engine should be shut off and allowed to cool before the bypass linkage levers are handled. CAUTION! Lead-acid batteries generate explosive gases. Keep sparks, flame and smoking materials away from batteries. Always wear eye protection when around batteries. • • • IMPORTANT INFORMATION The mower is equipped with a 12-volt negative grounded system. The other vehicle must also be a 12-volt negative grounded system. Do not use your mower to start other vehicles. WARNING! Make no adjustments without: the engine stopped, the ignition key removed, the park brake activated WARNING! Use extreme caution when loading the machine into a truck or trailer using ramps. There is the possibility of serious injury or death if the machine falls off the ramps. 19 MAINTENANCE Maintenance Schedule The following is a list of maintenance procedures that must be performed on the machine.

WARNING! Do not short battery terminals by allowing a wrench or any other object to contact both terminals at the same time. Before connecting battery, remove metal bracelets, wristwatch bands, rings, etc. Positive terminal must be connected first to prevent sparks from accidental grounding. IMPORTANT INFORMATION Do not attempt to open or remove caps or covers. Adding or checking level of electrolyte is not necessary. Always use two wrenches for the terminal screws. CAUTION! Always wear eye protection when around batteries. Park Brake Visually check that no damage is found on the steering control levers, links or switches belonging to the park brake. Perform a standstill test and check that there is sufficient braking action. To adjust the park brake, contact the Husqvarna service workshop. IMPORTANT INFORMATION The machine must be absolutely standing still when applying the park brake. 5. 6. Carefully remove the battery from the mower. Install new battery with cable terminals routed toward the center of the battery. 7. Reinstall battery hold-down and secure with nuts removed in Step 4. 8. Reconnect RED battery cable to positive (+) battery terminal with bolt and hex nut. 9. Connect BLACK grounding cable to negative (-) battery terminal with remaining hex bolt and hex nut 10. Replace terminal boot cover. 11. Lower seat WARNING! Faulty adjustment will result in reduced braking ability and can cause an accident. 22 MAINTENANCE Safety System Tire Pressures 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 / park brake controls are in the outer, locked neutral position. All tires should be at 15 psi / 103 kPa / 1 bar. IMPORTANT INFORMATION DO NOT add any type of tire liner or foam fill material to the tires. Excessive loads created by foam filled tires will cause premature failures. Only use O.E.M. specified tires. Caster Wheels 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. If the machine starts when one of these conditions is not met, turn the machine off and repair the safety system before using the machine again. Make sure the engine stops when the park brake is not engaged and the operator leaves the seated position. Check that the engine stops if the mower blades are engaged and the driver temporarily moves off the drivers seat. 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. IMPORTANT INFORMATION To be able to drive, the driver must sit in the seat and the steering / park brake controls must be moved into the engaged (outer) position. Otherwise the engine will stop. Hardware Check daily. Inspect the entire machine for loose or missing hardware. 23 MAINTENANCE Cutting Blades V-belts For the best mowing results, 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. 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 park brake. 2. Lower the deck into the lowest cutting position. 3. Remove bolts from belt shields and remove shields. 4. Remove any dirt or grass that may have accumulated around the cutter housings and entire deck surface. 5. Loosen the nut securing the belt guide. Pull the belt guide up out of the idler arm. 6. Push inward on the idler arm to release the tension on the belt. CAUTION! Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling. The sharpening of blades should be carried out by an authorized service workshop. Blade replacement 1. Remove blade bolt by turning counter clockwise. 2. Install new or resharpened blade with stamped GRASS SIDE facing towards ground/grass (down) or THIS SIDE UP facing deck and cutter housing. 3. Seat the blade's opening firmly onto the cutter housing. 4. Tighten blade bolt securely. 5. Torque blade bolt to 45-60 ft/lbs (60-81 Nm). 7. Carefully lift the belt over the top of the cutter housing pulleys and remove belt from the deck. Deck Belt Installation NOTE: For ease in installing the deck belt, refer to the routing decal on the top of the deck. 1. Wrap the deck belt around the electric clutch pulley located on the engine shaft. 2. Route the belt forward and up onto the deck. 3. Place belt around spring loaded idler pulley. 4. Wrap the belt around the stationary idler pulley and around the mandrel housings. 5. Push inward on the idler arm and carefully route belt over stationary idler pulley. Once the belt is properly routed, slowly release the idler arm to tension belt. 6. Double check belt routing to make sure it matches the decal affixed to the deck, and the belt does not have any twist. Correct if needed. 7. Set the loosened belt guide into the idler arm hole and tighten the pulley bolt. Replace belt shields on both mandrel housings and secure with fasteners. IMPORTANT INFORMATION Special blade bolt is heat treated. Replace with a Husqvarna bolt if required. Do not use lower grade hardware than specified. 24 MAINTENANCE Adjusting the Mower Deck adjustment. With an adjustable wrench, loosen the rear jam nut on the front suspension linkage. Make adjustment to level with the front lift link nut. Clockwise raises the front of the mower, counter clockwise will lower the front. Adjust the nut until rear blade tip is ¼" to 3/8" higher than the front blade tip. NOTE: This will place the mower deck in a standard measurement position. Depending on the type of grass being mowed or environmental conditions, additional adjustments may be required to achieve the desired cut. 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, the deck cannot be properly adjusted. Raise the deck to the highest (transport) position. 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. Turn each blade tip to align front to rear with the deck side-to-side. Cleaning 2. 3. Regular cleaning, 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 debris 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 the 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. For models fitted with a cleanout port, attach the quick connect (from the accessory packet) to any garden hose. After mowing, snap the hose to the cleanout port and turn on water supply. Measure from the floor surface up to the bottom of the blade tip on the discharge side of the mower deck. Record the measurement. Move to the opposite side, check that measurement is the same. If adjustment is required—with a ¾" or adjustable wrench, turn the lift link adjustment nuts on either side counter clockwise to lower or clockwise to raise. Adjust until both measurements are equal. Restart the mower and engage the blades to use the spinning action to wash away debris. Make sure the hose is away from the mower blades. Do not rinse hot surfaces with cold water. Let unit cool before washing. 4. Turn either blade to align with the deck front-to-rear. If the front blade tip does not measure ¼" to 3/8" higher in the rear, remove the foot plate access the front deck CAUTION! Use protective glasses when cleaning and washing. 25 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. 12/12 Every year Lubricate with grease gun 1/52 Every Week Filter change 1/365 Every day Oil change Level check 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. Wipe away excess grease after lubrication. It is important to avoid getting lubricant on the belts or the drive surfaces of the belt pulleys. Should this happen, attempt to clean them with spirits. If the belt continues to slip after cleaning, the belt must be replaced. Gasoline or other petroleum products must not be used to clean belts. Deck Spindles Lower the cutting deck completely. Lubricate with a grease gun, 2-3 strokes per spindle. IMPORTANT INFORMATION Use minimal lubrication and remove excess lubricant so that is does not come into contact with belts or belt pulley drive surfaces. Transmission The transmission is maintenance free with no need for level checks or oil changes. If a leak occurs, replace the unit or contact your Husqvarna dealer. 26 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 outer position Engine overloaded Battery is dead Poor ventilation around engine Contamination in the carburetor or fuel line Defective engine speed regulator Fuel supply shutoff valve is closed Too little or no oil in the engine Clogged fuel filter or fuel line Contamination in the carburetor or fuel line Ignition system faulty Fouled spark plugs Starter does not turn the engine over Battery not charging Battery is dead Poor contact of the battery terminal cable connections Poor contact of the battery terminal cable connections Charging lead is disconnected Blown fuse Machine moves slowly, unevenly, or not at all Fault in the starter safety circuit.

Clogged air filter Bent blades Fouled spark plugs Suspending for the mower deck is uneven Carburetor incorrectly adjusted Blades are dull Air trapped in hydraulic system Driving speed too high Machine vibrates Grass is too long Blades are loose Grass collected under the mower deck Blades are incorrectly balanced Engine is loose 27 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. Start the engine and allow it to run until the carburetor is drained of fuel or the stabilizer has reached the carburetor. 5. Remove the spark plug and pour about a tablespoon of engine oil into the cylinder. Turn over the engine so that the oil is evenly distributed and then refit the spark plug. 6. Lubricate all grease zerks, joints and axles. 7. Remove the battery. Clean, charge and store the battery in a cool place, but protect it from direct cold. 8. Store the machine in a clean, dry place and cover it for extra protection. The machine should be readied for storage at the end of the mowing season or if it will not be in use for more 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 to prevent the sticky residues that can occur during storage. Add stabilizer to the fuel in the tank or in the storage container. Always use the mixing ratios specified by the manufacturer of the stabilizer. Run the engine for at least ten minutes after adding the stabilizer so that it reaches the carburetor. Do not empty the fuel tank and the carburetor if stabilizer has been added. WARNING! Never store an engine with fuel in the tank indoors or in poorly ventilated spaces where fuel vapor can come in contact with open flames, sparks, or a pilot light such as in a boiler, hot water tank, clothes dryer, etc. Handle the fuel with care. It is very flammable and can cause serious personal injury and property damage. Drain the fuel into an approved container outdoors and store far away from open flame or sources of ignition. Never use gasoline for cleaning. Use a degreaser and warm water. 28 Service When ordering spare parts, please specify the purchase year, model, type, and serial number. Always use genuine Husqvarna spare parts. An annual check-up at an authorized service workshop is a good way to ensure that your machine performs its best the following season. 28 SCHEMATIC 29 TECHNICAL DATA Engine Frame Manufacturer Briggs & Stratton Cutting Width 42" / 107cm Type Endurance Commercial Cutting Height 1.5" - 4" / 3.8 - 10.2 cm Power 22 Uncut Circle 0 Lubrication Pressure with oil filter Number of Blades 2 Fuel Min 87 octane unleaded (Max Blade Length ethanol 10%, Max MTBE 15%) 21" / 53.3 cm Fuel tank capacity 3½ gallons / 13.25 litres Nose Roller Yes Cooling Air cooled Sprung Seat Standard Air filter Standard Hinged Arm Rests Optional Alternator 12V Service Meter Digital Starter Electric Blade Engagement Electromagnetic Clutch 1) Deck Construction Fabricated Transmission Hydrostatic transaxles Productivity 2.2 acres/h / 8,093 m2/h Steering control Dual levers, foam gripped Dimensions Speed forward 0-6.5 mph / 0-10.5 km/h Weight 580 lbs / 263 kg Speed reverse 0-3.5 mph / 0-5.6 km/h Base Machine Length 75" / 191 cm Brakes Mechanical park brake Base Machine Height 40" / 102 cm Front caster tires 11 x 6-5 Base Machine Width 41.5" / 106 cm Rear tires, turf pneumatic 18 x 8.5-8 Overall Width, Chute Up 48" / 122 cm Tire pressure 15 PSI / 103 kPa / 1 bar Overall Width, Chute Down 56" / 142 cm Transmission 1) The power rating as declared by the engine manufacturer is the average gross power output at the specified RPM of a typical production engine for the engine model measured using SAE Standards for engine gross power.
