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).
