CONTROLS Controls This operator’s manual describes the Husqvarna Zero Turn Rider. The rider is fitted with a Kawasaki or Kohler four-stroke V-Twin engine developing 23-27 horse power. Transmission from the engine is made via two belt-driven hydraulic pumps, which in turn drive a hydraulic motor for each drive wheel.
Page 18
CONTROLS 1. Motion Control Levers 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.
Page 19
CONTROLS 2. Hour Meter The hour meter displays the total operating time. It will flash CHG OIL (Change Oil) at 50 hour intervals. The flash duration is one hour before and one hour after the interval. The CHG OIL icon will come on and shut off automatically.

MAINTENANCE Checking the Engine's Cooling Air Intake Check that the engine’s cooling air intake is free from leaves, grass, and dirt. If the cooling air intake is clogged, engine cooling deteriorates, which can lead to engine damage. Checking and Adjusting the Throttle Cable The illustations show Kawasaki engine.
Page 43
MAINTENANCE Cyclon air filter maintenance If the engine seems weak or runs unevenly, the air filter may be clogged. If running with a dirty air filter, the spark plugs can become fouled. For this reason, it is important to replace the air filter regularly (see the heading Maintenance Schedule for the proper service interval).
Page 44
MAINTENANCE Filter replacement Remove the end cover. Remove the main filter (outer filter) by pulling it out by hand. Remove the inner filter by pulling it out by hand. Clean inside of the filter housing. Wipe dry only. Install the inner filter with the open end first.
Page 45
MAINTENANCE Replacing the Fuel Filter Replace the line-mounted fuel filter every 100 hours (once per season) or more often if it becomes clogged. Replace the filter as follows: Move the hose clamps away from the filter. Use flat-nosed pliers. Pull the filter loose from the hose ends. Push the new filter into the hose ends.

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.
Page 50
MAINTENANCE To adjust 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.
Page 51
MAINTENANCE Cleaning and Washing Regular cleaning and washing, especially under the mower deck, will increase the machine’s lifespan. 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.
