Located on control panel.

The ignition switch is used to start and stop the engine. The switch has three positions “OFF”, “RUN” and “START” ( Figure 4). Insert key into switch and rotate clockwise to the “ON” position. Rotate clockwise to the next position to engage the starter (key must be held against spring pressure in this position).

Ignition switch

Note: Brake must be engaged, motion control levers out (neutral lock position) and PTO switch “OFF” to start engine. (It is not necessary for the operator to be in the seat to start the engine.)

Turning the key to the Off position will stop the engine; however, always remove the key when leaving the machine to prevent someone from accidentally starting the engine

Blade Control Switch (Power Take-Off)

Located on the control panel.

The blade control switch, represented by a power take-off (PTO) symbol, engages and disengages power to the mower blades (see Figure 4).

Pull out on the blade control switch to “On” to engage the blades.

Push the blade control switch to “Off ” to disengage the blades.

Throttle/Choke Lever

Located on control panel.

The throttle is used to control engine speed. Moving throttle lever forward will increase engine speed and moving throttle lever to the rear will decrease engine speed. Moving the throttle forward into the detent is full throttle (see Figure 4).

The choke is used to aid in starting a cold engine. Do Not run a warm engine with the choke in the “ON” position. Moving the lever forward beyond the detent will put the choke in the “ON” position and moving the lever to the detent will put the choke in the “OFF” position.

Motion Control Levers

The motion control levers located on each side of the seat (Figure 3).

The motion control levers are speed sensitive controls of independent wheel motors. Moving a lever forward or backward turns the wheel on the same side forward or in reverse; wheel speed is proportional to the amount the lever is moved. Moving the control levers outward from the center position locks them in the neutral position. Always position the motion control levers into the neutral position and engage the park brake lever when you stop the machine or leave it unattended. The unit must be tied down and brake engaged when transporting.
