Page 17: Controls
This operator’s manual describes the Husqvarna Zero Turn Rider. The rider is fitted with either a Kohler or Briggs & Stratton four-stroke overhead valve engine. 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: Steering Control Levers
Steering 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: Seat Adjustment Knobs
Seat Adjustment Knobs The seat can be adjusted lengthways. When making adjustments, loosen the four knobs under the seat pan, after which the seat can be moved backward or forward. Retighten the knobs at the desired setting. Fuses The fuses are located in a holder at the right hand side of the battery compartment.
Page 20: Refueling
Refueling Read the safety instructions before refueling. The machine has one fuel tank, just behind the seat. The tank capacity is 3 gallons (11.4 liters). Regularly check the gas cap gasket for damage and keep the cap properly tightened. The engine will run on a minimum of 85-octane unleaded gasoline (no oil mix).
Page 21: Blade Switch
Blade switch To engage the mower deck, pull the blade switch knob out. The mower blades are disengaged when the knob is pressed down fully. Ignition Switch The ignition key is placed on the control panel and is used to start and stop the engine. WARNING! Do not run the starter for more than five seconds each time.
Page 22: Throttle Control
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 back respectively.
Page 23: Accessories
Lifting Lever for the Mower Deck The deck cutting height is achieved with the foot pedal. To lift the deck, press the foot pedal forward. To lower the deck, apply pressure to the top side of the foot pedal and allow the pedal to pivot while allowing the lift arm to rotate to the rear of the unit.
Page 24: Training
Read the “Safety Instructions” section and the 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.
Page 25: Before Starting
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.
