CONTROLS This operator’s manual describes the Husqvarna Zero Turn Rider. The rider is fitted with either a Briggs & Stratton or Kohler four-stroke overhead valve engine developing 20 - 26 horse power.* Transmission from the engine is made via two beltdriven hydraulic integrated zero turn transaxles (IZTs). Using the left and right steering controls, the flow is regulated and thereby the direction and speed. *As rated by the engine manufacturer. Zero Turn Rider Control Locations 8011-769-2 1. 2. 3. 4.
CONTROLS Parking Brake IMPORTANT INFORMATION The machine must stand absolutely still when applying the parking brake. Always set the parking brake before dismounting. Release the parking brake before moving the mower. The parking brake is found on the left of the machine. Pull the lever backward to activate the brake and forward to release it.
CONTROLS Tracking If the mower is not tracking straight, check the air pressure in both rear tires. Recommended air pressure is 15 psi. (1 bar) Tracking must be checked on a flat and level concrete or blacktop surface. If the unit still does not track straight contact your Husqvarna workshop for adjustments. Fuel Shut Off Valve The fuel shut off valve is located under the fuel tank. The valve has two positions; ON and OFF.
CONTROLS Refueling Read the safety instructions before refueling. The machine has one fuel tank, just behind the seat. The tank volume is 5.4 gallons (20.4 liters). Make sure the fuel cap is properly tightened and the cap gasket is not damaged. The engine will run on a minimum of 85-octane unleaded gasoline (no oil mix). Environmentally adapted alkylate gasoline can be used beneficially. See also Technical Data concerning ethanol fuel. Methanol fuel is not allowed. WARNING! Gasoline is highly flammable.
CONTROLS By Pass Linkage When pushing or pulling the mower, be sure to engage the IZT (Integrated Zeroturn Transaxle) bypass linkages. The IZT bypass linkages are located on the rear of the frame, below the rear engine guard. • Raise the deck into the highest cutting position. CZ10-2 1. IZT Bypass linkage Bypass linkages • Pull the IZT bypass linkages out and into • the slots and release so that it is held in the bypass position.

The CHG OIL icon will come on and shut off automatically. The hour meter can not be manually reset. Hour meter 8011-759 Choke Control The choke control is used for cold starts in order to provide the engine with a richer fuel mixture. For cold starts the control should be pulled out.
CONTROLS Throttle Control 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. In order to increase or decrease the engine speed, the control is moved forward or backward 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 Cutting Height Pedal The cutting deck height is obtained by pressing the foot pedal lift arm forward and releasing the transport latch. Then lower the deck to the preset height. To raise the deck push forward on the foot pedal lift arm until the transport latch locks. The cutting height range is from 1½" (38 mm) to 4 ½" (114 mm) in ¼" (6.4 mm) increments. The heights are measured from the ground up to the blade tip with the engine not running.
OPERATION Operation Read “Safety Instructions” section and following pages, if you are unfamiliar with the machine. Training Zero turn mowers are far more maneuverable than typical riding mowers due to their unique steering capabilities. We suggest that this section be reviewed in its entirety prior to attempting to move the mower under its own power.
OPERATION Before Starting • Read the sections Safety Instructions and Controls before starting the machine. • Perform the daily maintenance before starting (see Maintenance Schedule in the Maintenance section). • Check that there is sufficient fuel in the fuel tank. • Adjust the seat to the desired position. The following conditions must be fulfilled before the engine can be started: • The driver must be seated on the seat. • • • The blade switch for engaging the mower blades must be depressed.
OPERATION 5. Move the steering controls outward to the locked (outer) neutral position. 8011-724 Steering controls in the outward, locked neutral position 6. Move the throttle to the middle position. Set the throttle 8011-763 7. If the engine is cold, the choke control should be pulled out to its extents.

When the engine starts, immediately release the ignition key back to the run position. STOP IMPORTANT INFORMATION Do not run the starter for more than 5 seconds each time. If the engine does not start, wait about 10 seconds before retrying.
OPERATION 11. Press the choke control in gradually when the engine has started. Gradually press in the choke control 8011-756 12. Set the desired engine speed with the throttle. Allow the engine to run at a moderate speed, “half throttle”, for 3-5 minutes before loading it too heavily. USE FULL THROTTLE WHEN MOWING (no choke). WARNING! Engine exhaust and certain vehicle components contain or emit chemicals considered to cause cancer, birth defects or other reproductive system damage.
OPERATION Weak Battery WARNING! Lead-acid batteries generate explosive gases. Keep sparks, flame and smoking materials away from batteries. Always wear eye protection then around batteries. If your battery is too weak to start the engine, it should be recharged. (See “Battery” in the Maintenance Section.) IMPORTANT INFORMATION Your 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.
OPERATION Running 1. Release the parking brake by moving the lever downward. Your 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 parking brake will shut off the engine. 2. Move the steering controls to the neutral position (N). Released parking brake 8011-711 3. Select the cutting height by adjusting the cutting height pin. Release latch and lower deck to set cutting height.
OPERATION 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. Turning on the spot can be achieved by moving one control backward (behind the neutral position) and carefully moving the other steering control forward from its neutral position.
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. 1. Disengage the mower deck by depressing the blade switch. 8011-668 Disengage the mower deck 2.

Check and clean the cooling air intake 8011-719 Throttle Cable Check that the engine responds to throttle increases and that a good engine speed is attained at full throttle.
MAINTENANCE Air Filter Briggs & Stratton Engine Standard air filter If the engine seems weak or runs unevenly, the air filter may be clogged. If run with a dirty air filter, the spark plugs can become fouled disrupting operation. For this reason, it is important to replace the air filter regularly (see the heading Maintenance Schedule for the proper service interval).
MAINTENANCE Air Filter Kohler Engine These engines are equipped with a replaceable, high density paper air cleaner element. Some engines are also equipped with an oiled, foam precleaner which surrounds the paper element. Two different capacity air cleaner systems are available. Check the air cleaner daily or before starting the engine. Check for a buildup of dirt and debris around the air cleaner system. Keep this area clean. Also check for loose or damaged components.
MAINTENANCE Heavy Duty Air Filter If the engine seems weak or runs unevenly and the dust load indicator has turned red the air filter may be clogged. If run with a clogged air filter, disruption of operation can occur. Cleaning/replacing the air filter is carried out as follows: Only do so when the dust indicator is red. WARNING! The engine and the exhaust system, become very hot during operation. Risk for burns if touched.
MAINTENANCE Fuel Filter Replace the line-mounted fuel filter every 100 hours (once per season) or more regularly if it is clogged. Replace the filter as follows: 1. Move the hose clamps away from the filter. Use flat-nosed pliers. 2. Pull the filter loose from the hose ends. 3. Push the new filter into the hose ends. Position the filter with the “FLOW” arrow pointing up toward the fuel pump. If necessary, a soap solution can be applied to the filter ends to ease mounting. 4.
MAINTENANCE Parking Brake Visually check that no damage is found on the lever, links, 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. WARNING! Faulty adjustment result in reduced braking ability and can cause an accident. The parking brake in the disengaged position 8011-711 IMPORTANT INFORMATION V-belts Check every 100 hours of operation.

MAINTENANCE IZT Belt 3 4 To replace IZT (Integraded Zeroturn Transaxle) belt Park the mower on a level surface. Engage the park brake. IZT belt removal NOTE: Be careful not to damage the fan blades on the IZT as this can affect cooling or damage the IZT • Remove the deck belt (see to replace deck belt in this section of the manual). • Create slack in the belt by either removing the spring on the pump idler arm or inserting 1/2” breaker bar into the square hole on the spring loaded idler.
MAINTENANCE Cutting Blades In order to attain the best mowing effect, it is important that the blades are well sharpened and not damaged. WARNING! Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling. 8011-604 Check the blades Bent or cracked blades or blades with large nicks should be replaced. Damaged blades should be replaced when hitting obstacles that result in a breakdown.
MAINTENANCE Blade replacement WARNING! 4 1 2 Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling. 3 • Remove blade bolt by turning counterclockwise. IMPORTANT INFORMATION To ensure proper assembly, center hole in blade must align with star on cutter housing. • Install new or re-sharpened blade with stamped “GRASS SIDE” facing towards ground/grass (down) or “THIS SIDE UP” facing deck and cutter housing. • Install and tighten blade bolt securely.
MAINTENANCE Adjusting the Mower Deck WARNING! Before performing any service or adjustment checklist: 1. Engage the parking brake. 2. Place the Blade switch in the disengaged position. 3. Turn ignition switch to “OFF” position and remove the key. 4. Make sure the blades and all moving parts have completely stopped. 5. Disconnect the spark plug wire from all spark plugs and place the wire where it cannot come in contact with the plug.
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. Antiscalp 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. CZ-9 Anti-scalp roller 1.
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.
MAINTENANCE Parking Brake Adjusting the parking brake Jack up unit and support properly with jack stands. Allow clearance to work at rear transaxles. Before making any adjustments: Set park brake. Measure the distance between the rod swivel pin and the brake arm washer. With the brake engaged, there should be a gap of 1/8" to ½" (3 mm to 13 mm) between the swivel pin and the brake arm washer. If measurement is out of range adjust as follows: Disengage park brake lever.
LUBRICATION Lubrication Schedule EZ 7 8011-672-2 12/12 Every year 1/52 Every Week 1/365 Every day Lubricate with grease gun Oil change Lubricate with oil can Level check Filter change *Change transaxles (transmission) filters. 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.
LUBRICATION Lubricating the Cables If possible, grease both ends of the cables and move the controls to end stop positions when lubricating. Refit the rubber covers on the cables after lubrication. Cables with sheaths will bind if they are not lubricated regularly. If a cable binds, it can disrupt operation. If a cable binds, remove the cable and hang it vertically. Lubricate it with light engine oil until the oil begins to escape from the bottom.
LUBRICATION Deck Outer Spindle Lubricate using a grease gun, one zerk, each side 2-3 strokes. Use only good quality bearing grease. Engine Oil Changing the Engine Oil The engine oil should be changed for the first time after 5-8 hours of operation. Thereafter, it should be changed every 50 hours. WARNING! Engine oil can be very hot if it is drained directly after stopping the engine. Allow the engine to cool somewhat first.
LUBRICATION Oil Levels Check the oil level in the engine when the machine is standing level and the engine is stopped. Remove the dipstick, wipe it clean, and then replace it. The dipstick should be screwed into place. Take the dipstick out again and read the oil level. 8011-500 Remove the dipstick The oil level should lie between the markings on the dipstick. If the level is approaching the “ADD” mark, fill the oil to the “FULL” mark on the dipstick. Never fill to above the “FULL” mark.
LUBRICATION Engine Oil Filter 1. Drain the engine oil in accordance with the work description under the heading Engine Oil/Change Engine Oil. 2. Remove the oil filter. If necessary, use a filter remover. 3. Wipe new, clean engine oil onto the seal for the new filter. 4. Mount the filter by hand with + ¾ turn. 5. Run the engine warm, then check that there are no leaks around the oil filter seal. 6. Check the oil level in the engine, fill if necessary. The oil filter holds 0.1 qt (0.1 liters) of oil.
LUBRICATION 7. Drain old oil filters of all free flowing oil prior to disposal. Place used oil in appropriate containers and dispose of it in accordance with laws in your area. 8. Remove the top port plug (see illustration) from the left side and right side of the transaxles prior to filling with oil. This will allow the transaxles to vent during oil fill. 9. Remove the cap from the transaxles’ expansion tank located on the vehicle frame. 10.
LUBRICATION Purging Procedures Due to the effects air has on efficiency in hydrostatic drive applications, it is critical that it is purged from 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. The resulting symptoms in hydrostatic systems may be: 1. Noisy operation. 2. Lack of power or drive after short term operation. 3.
