Speed Balancing Adjustment; Neutral Adjustment - Ferris IS2000Z Series Operator's Manual

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 turning the adjustment bolt(s) (A,
Figure 30). Only adjust the speed of the wheel that is
traveling faster.
To Reduce the Speed of the Faster Wheel
1. Loosen the securing nut.
2. Turn the top speed adjustment bolt COUNTER-
CLOCKWISE to reduce the speed.
3. Retighten the securing nut when adjustment is
complete.
WARNING
DO NOT adjust the tractor for a faster overall
speed forward or reverse than it was designed
for.

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.
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 31) on the linkage
rod. The first two are to be used together to turn
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 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 (B) against 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 achieved neutral, depending upon how
much the machine creeps.
