2. Open the hood.
3. The hood latch is spring loaded and will automatically
latch the hood in place when the hood is closed.

Neutral Adjustment

If the unit "creeps" while the ground speed control levers are
locked in NEUTRAL, then it may be necessary to adjust the
control linkage.
1. Park the unit on a flat, level surface such as a concrete
floor. Disengage the PTO, engage the parking brake, turn
the ignition switch to OFF, and remove the ignition key.
2. Loosen the jam nuts (A, Figure 61) and turn the
adjustment linkage (B) to adjust. If the unit creeps
forward, turn the linkage clockwise (while standing at
the rear of the unit, facing forward), if the unit creeps
backward, turn the linkage counter-clockwise.

3. Lock the jam nuts when neutral is achieved.
Note: This adjustment should not be performed while the unit
is running. It may take several attempts to achieve neutral,
depending upon how much the unit creeps.
Neutral Position and Return Spring
Adjustment
To determine if it is necessary to adjust the neutral position,
perform the following steps:
1. Park the unit on a flat, level surface such as a concrete
floor. Disengage the PTO, engage the parking brake, turn
the ignition switch to OFF, and remove the ignition key.
2. Move the ground speed control levers in to the operating
position, pull levers rearward, and release.
3. Move the ground speed control levers out towards the
neutral position. If the levers do not align with the notches
in the neutral lock plates, it is necessary to adjust the
reverse return bolts (A, Figure 62).

Neutral Position Adjustment
1. Loosen the jam nut (B, Figure 62) locked against the
clevis.
2. Turn the reverse return bolt (A) clockwise to adjust
handle rearward, counter-clockwise to adjust handle
forward.
3. Pull lever rearward and release to check position again.
Adjust as necessary to align levers with notches.
4. Once the lever alignment has been adjusted, lock jam nut
against the clevis.
Return Spring Adjustment
After adjusting the neutral position, lock the levers in the
neutral position and measure the reverse return spring (C,
Figure 62) length. This should be 2-3/8" (6,03 cm) long. If not,
hold the reverse return bolt (A) with a wrench while turning
the spring position nut (D) until the measurement is achieved.
