3.OPERATION INSTRUCTIONS

3.1CONTROLS

3.1.1Familiarize yourself with all controls before operating the mower.

3.1.2Motion Control Levers: Located on each side of the console. The left lever controls the flow of hydraulic oil from the left hydrostatic pump to the left drive wheel motor. The right lever controls the flow of hydraulic oil from the right hydrostatic pump to the right drive wheel motor.

IMPORTANT: To begin movement (forward or backward) the operator must be in the seat, the brake lever must be disengaged (pushed down) before the motion control levers can be moved in or the engine will kill.

When levers are centered in the T-slot the drive system is in the neutral position. With levers moved out in the T-slot the drive system is in the neutral lock position See Figure 2.

FIGURE 2

By moving both levers an equal amount forward or back from the neutral position the machine can be caused to move forward or backward in a straight line.

Movement of the left lever forward will cause the left drive wheel to rotate in a forward direction. Movement of the right lever forward will cause the right drive wheel to rotate in a forward direction. To stop forward travel, pull the levers back to the neutral position.

To turn left while moving forward, move the left lever back toward neutral to slow the left drive wheel.

To turn right while moving forward, move the right lever back toward neutral to slow the right drive wheel.
