NEUTRAL POSITION AND RETURN
SPRING ADJUSTMENT
To determine if it is necessary to adjust the neutral posi-
tion, perform the following steps.
1. Disengage the PTO, engage the parking brake and
turn off the engine.
2. Move the ground speed control levers in the operat-
ing position, pull levers rearward and release.
3. Move the ground speed control levers towards the
neutral position. If the levers do not align with the
notches in the neutral lock plate, it is necessary to
adjust the reverse return bolts (A, Figure 28).
Neutral Position Adjustment
1. Loosen the jam nut (D) locked against the clevis.
2. Turn the reverse return bolt (A) clockwise to adjust
handle rearward, counter-clockwise to adjust handle
forward.
4. Pull lever rearward and release to check position
again. Adjust as necessary to align levers with
notches.
5. 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
(B) length. This should be 2-3/8” long. If not, hold the
reverse return bolt (A) with a wrench while turning the
spring position nut (C) until the measurement is
achieved.
