Troubleshooting, Adjustment & Service
Return-to-Neutral Adjustment
To determine if it is necessary to adjust the neutral
return, perform the following steps.
1. Disengage the PTO, engage the parking brake
and turn off the engine.
2. Move the ground speed control levers into 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 plate, it is
necessary to adjust the neutral return rod.
To Adjust:
1. Loosen the set collar (B, Figure 32) locked against
the return spring (A).
2. Lock the ground speed control levers in neutral.
3. Tighten set collar against the return spring.
4. Pull lever rearward and release to check that the
lever stops aligned with notch in the neutral lock
plate.
It is important to note that after every adjustment of
the neutral return spring, the lever must be returned
to locked position to properly check the neutral
position.

Parking Brake Adjustment

1. Disengage the PTO, engage the parking brake,
stop the engine and remove the ignition key.
2. Raise the seat plate.
3. Locate the brake spring (A, Figure 33).
4. With the parking brake engaged, measure the
compressed spring length. The spring should be
1-15/16" - 2" (4,9 - 5,1 cm) when compressed.
5. If the spring is not within this range, release the
parking brake and turn the adjustment nut (B) to
compress or release the spring.
6. Engage the parking brake and remeasure the
spring.
CAUTION
Do not adjust the spring to be shorter than
1-15/16" (4,9 cm) when compressed. This may
damage the brake mechanism.
If this does not correct the braking problem, see
your Ferris dealer.
