Neutral Adjustment; Speed Balancing Adjustment; S/N: 2014523387 & Below - Snapper SW20 Series Operator's Manual

Neutral Adjustment

If the unit "creeps" while the forward speed control lever is
locked in the NEUTRAL position, 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.
CAUTION
This adjustment should not be performed while the
machine is running.
2. There are two jam nuts (B, Figure 23) on the linkage rod
(A). Loosen the jam nuts on the linkage rod and turn
the linkage rod to adjust. If the machine creeps forward,
turn the rod COUNTER-CLOCKWISE (while standing at
the rear of the machine, looking down), if the machine
creeps backward, turn the rod CLOCKWISE.
3. Lock the jam nuts (B) against the ball studs 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.

Speed Balancing Adjustment

(2014523387 & Below)
If the unit veers to the right or left when you are driving the
machine, the top speed of each wheel can be balanced by
turning the linkage adjuster rod (C, Figure 24). Only adjust
the speed of the wheel that is traveling faster.
To Reduce the Speed of the Faster Wheel:
1. Loosen the jam nut (B).
2. Turn the linkage adjuster rod COUNTER-CLOCKWISE to
reduce the speed.
3. Retighten the jam nut when adjustment is complete.
WARNING
Do NOT adjust the tractor for a faster overall speed
forward or reverse than it was designed for.
