MOWING HEIGHT ADJUSTMENT
The cutting height adjustment pin (A, Figure 31)
controls the mower cutting height. The cutting height
is adjustable between 1-3/4” (4,4 cm) and 4-1/2” (11,4
cm) in 1/4” (0,64 cm) increments.
1. Depress the deck lift foot pedal (B) until it locks
into the 4-1/2” (11,4 cm) position.
2. Place the cutting height adjustment pin in the
desired cutting height.
3. Depress the deck lift foot pedal then push the lock
lever (C) towards the right to release the lock.
4. Release the deck lift foot pedal until it comes to
rest against the cutting height adjustment pin.

NEUTRAL ADJUSTMENT
If the tractor “creeps” while the ground speed control
levers are locked in NEUTRAL, then it may be
necessary to adjust the linkage rod.
NOTE: Perform this adjustment on a hard, level
surface such as a concrete floor.
1. Disengage the PTO, engage the parking brake
and turn off the engine.
2. There are three nuts (B, Figure 30) on the linkage
rod. The first two are to be used together to turn
the rod and the third (towards the front of the
machine) is used to lock the rod in place. Loosen
the jam nut that locks against the ball joint (B,
Figure 30) and turn the linkage rod (A) to adjust.
If the machine creeps forward, turn the rod
CLOCKWISE (while standing at the rear of the
machine, facing forward), if the machine creeps
backward, turn the rod COUNTER-CLOCKWISE.
3. Lock the jam nut (B) against the ball joint when
neutral is achieved.
NOTE: This adjustment should not be performed
while the machine is running. It may take several
attempts to achieved neutral, depending upon how
much the machine creeps.
