Neutral Adjustment; Return-To-Neutral Adjustment; Parking Brake Adjustment - Ferris IS2000Z Series Operator's Manual

Neutral Adjustment

If the tractor "creeps" while the ground speed control levers are
locked in the 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 41) on the linkage rod. The
first two are to be used together to run 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 (C)
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 agains 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 achieve
neutral, depending on how much the machine creeps.

Return-to-Neutral Adjustment

Determining If Adjustment is Necessary
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 rearward and release.
3. Move the ground speed control levers out towards the
NEUTRAL position.
• If the levers align with the notches in the neutral lock
plate, no adjustment is necessary.
• If the levers do not align with the notches in the neutral
lock plate, adjustment is necessary.

neutral return rod, the lever must be pulled rearward and released
to properly check the neutral position.
