Neutral Adjustment

The neutral system for this unit consists of two neutral linkage
rods and a pivot that connects the ground speed control
lever to the transmission. The lower rod that connects the
transmission to the pivot is factory preset and should not be
changed for neutral adjustment purposes. The adjustment is
achieved by changing the length of the upper rod (A, Figure
47) that connects the ground speed control lever to the pivot.

Determining if Adjustment is Necessary: If the unit
"creeps" while the ground speed control levers are locked in
the NEUTRAL LOCKOUT position, then it may be necessary
to adjust the linkage rods.
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 two nuts (B) on the linkage rod. Loosen the
nuts from the ball joints (C) and turn the linkage rod to
adjust.
• If the unit creeps forward, turn the rod clockwise
(while standing at the rear of the unit, facing forward);
• If the unit creeps backward, turn the rod counter-
clockwise (while standing at the rear of the unit,
facing forward).
3. Lock the jam nut against the ball joints 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 on how much the unit creeps.

Prior to performing this procedure the Neutral Adjustment
procedure must be completed.
WARNING
To avoid serious injury, perform adjustments only with the

spring (C).
4. Move the ground speed control levers into the operating
position, pull rearward, and release.
