Operation

Driving the Machine

CAUTION

Machine can spin very rapidly by positioning one lever too much ahead of the other. Operator may lose control of the machine, which may cause damage to the machine or injury.

Use caution when making turns.

Slow the machine down before making sharp turns.

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 stop.

When the motion control levers are positioned fully outward (apart) in the T-slot, the drive system is in the neutral lock position (Figure 7).

When the motion control levers are moved directly inward (together) the drive system is in the neutral operate position.

Driving Forward

1.Release the parking brake.

2.Move the motion control levers inward to the center to the neutral position.

3.To move forward in a straight line, move both levers forward with equal pressure.

To turn left or right, pull the motion control lever back toward neutral in the desired turn direction.

The machine will move faster the farther the motion control levers are moved from the neutral position.

4.To stop, position both motion control levers in the neutral operate position.

Driving in Reverse

1.Move the motion control levers inward to the neutral operate position.

2.To move rearward in a straight line, move both levers rearward with equal pressure.

To turn right, release pressure on the RH motion control lever and the rear of the machine will move towards the rear and to the right.

To turn left, release pressure on the LH motion control lever and the rear of the machine will move towards the rear and to the left.

3.To stop, position both motion control levers in the neutral operate position.

Adjusting the Cutting Height

The cutting height of the mower deck is adjusted from 1 to 5 inches (2.54 cm to 12.7 cm) in 1/4 inch (6.4 mm) increments.

1.Stop the machine and move the motion control levers outward to the neutral locked position.

2.Disengage the PTO.

3.Raise the deck height lever to the transport position (also the 5 inch (12.7 cm) cutting height position)(Figure 9).
