CONTROLS Controls This operator’s manual describes the Husqvarna Zero Turn Rider. The mower is fitted with a liquid cooled, 3 cylinder Daihatsu diesel engine (27 HP) or Daihatsu Turbo diesel engine (34 HP) Transmission from the engine is made via two belt-driven hydrostat transaxles, which in turn drive a hydraulic motor for each drive wheel. Using the left and right steering controls, the flow is regulated and thereby the direction and speed.
CONTROLS Gauges 1 Water temperature gauge- indicates coolant temperature and warns of overheat situation. Ammeter - indicates amount of electrical flow at the battery. Under normal operating conditions the needle will be slightly on the plus (+) side of the gauge, showing that current is being supplied to the battery. At idle speed, the indicator may be at zero or on the negative (-) side.
CONTROLS Engaging the Mower Deck In order to engage the mower deck, pull the knob out; the mower deck is disengaged when the knob is depressed. Deck should be engaged at mid throttle and disengaged at idle speed to prolong clutch life. BAM-2 Engaging the mower deck Parking Brake The parking brake is found on the left of the machine. Pull the lever back to activate the brake and push forward to release it.
CONTROLS Motion Control Levers The machine’s speed and direction are continuously variable using the two motion control levers. The motion control levers can be moved forward or backward from a neutral position. Furthermore, there is a neutral position, which is locked if the motion control levers are moved outward into the neutral slots. When both controls are in the neutral position (N), the machine stands still. The motion control levers on each side of the mower control the direction of movement.
