NEUTRAL ADJUSTMENT
-NOTE-
Neutral has been set by your Scag dealer at the
time of set up and normally does not need to be
adjusted. If, however, you find that the neutral
has come out of adjustment, follow the procedure
below.
Be sure the dump valves are in the run position and 1.
the speed control lever is in the neutral lock position.
With an operator in the operating position, park the 2.
machine on a flat level surface, start the engine and
disengage the parking brake.
Run the engine at full operating speed and check if 3.
the machine creeps forward or backwards.
Adjust the RH wheel by loosening the jam nuts on 4.
the steering control rod and turning the rod until the
drive wheel turns in the forward direction. Turn the
rod back until the drive wheel stops moving. Turn the
rod an additional 1/2 turn. See Figure 6-2.
