Ground Speed Control Lever
Adjustment

The ground speed control levers can be adjusted in three
ways. The alignment of the control levers, the placement of
the levers (how close the ends are to one another) and the
height of the levers can be adjusted.

To Adjust the Handle Alignment

Loosen the ground speed control lever mount bolts (D,
Figure 40) and pivot the lever(s) (C) to align with each other.

To Adjust the Handle Placement

Loosen the jam nuts and adjust the placement bolt (B) in or
out to properly adjust the lever end spacing.

To Adjust the Handle Height

Remove the mounting hardware (D) and reposition the
handle either up or down from its original position. You will
need to readjust the handle alignment as described above.

Speed Balancing Adjustment

If the rider veers to the right or left when the ground speed
control levers are in the maximum forward position, the top
speed of each of these levers can be balanced by adjusting
the top speed adjustment bolt(s) (A, Figure 40). Only adjust
the speed of the wheel that is traveling faster.

Neutral Adjustment

If the tractor “creeps” while the ground speed control levers
are locked in NEUTRAL, then it may be necessary to adjust
the linkage rod.

1. Park the machine on a hard, level surface such as a
concrete floor. Disengage the PTO, engage the parking
brake, and turn off the engine.

CAUTION

This adjustment should not be performed while the
machine is running.

2. The locking nuts (A, Figure 41) are to be used together
to turn the rod. Loosen the jam nut that locks against
the ball joint (B) and turn the linkage rod (C) 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 (while standing at the rear of
the machine, facing forward).

3. Lock the jam nut (D) against the ball joint (B) when
neutral is achieved.

4. Start the engine.

5. Disengage the parking brake and lock the ground speed
control levers in the neutral position.

6. If the machine still “creeps,” repeat the Neutral
Adjustment procedure. It may take several attempts to
achieve neutral, depending on how much the machine
creeps.

off the engine.

2. Move the ground speed control levers into the operating
position, pull the 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.

Adjustment:

1. Loosen the set collar (B, Figure 42) locked against the
return spring (A).

2. Lock the ground speed control levers in neutral.

3. Tighten the set collar snug against the return spring

4. Pull the ground speed control levers rearward and
release to check that the lever stops aligned with the
notch in the neutral lock plate.
