Tracking Adjustment
Stop the engine and remove the key from the
ignition before making any adjustments. Wait for
all moving parts to come to a complete stop
before beginning work.
The engine and drive unit can get hot during
operation causing burn injuries. Allow engine
and drive components to cool before making any
adjustments.
-NOTE-
Before proceeding with this adjustment, be sure
that the caster wheels turn freely and that the tire
pressure in the drive wheels is correct. If the tire
pressure is not correct, the machine will pull to
the side with the lower pressure.
1. If at full speed the mower pulls right, it is an
indication that the left wheel is turning faster than the
right wheel. To adjust this condition, proceed as
follows:
A. Stop the machine and place the steering control
levers in the neutral position. Loosen the lock
nuts securing the ball joints at each end of the
LH steering control rod. Rotate the control rod
to shorten the rod and tighten the lock nuts.
This will cause the control rod to stroke the LH
pump less, slowing down the LH wheel. (See
Figure 6-4).
-NOTE-
If after making the adjustment as outlined in step
1A, the machine creeps forward or backward, the
neutral adjustment must be made as described on
page 19.
2. If at full speed the mower pulls left, it is an indication
that the right wheel is turning faster than the left
wheel. To adjust this condition, proceed as follows:
CAUTION:
CAUTION:
A. Stop the machine and place the steering control
levers in the neutral position. Loosen the lock
nuts securing the ball joints at each end of the
RH steering control rod. Rotate the control rod
to shorten the rod and tighten the lock nuts.
This will cause the control rod to stroke the RH
pump less, slowing down the RH wheel. (See
Figure 6-3).
6.5 BELT ALIGNMENT
Belt alignment is important for proper performance of
your Scag mower. If you experience frequent belt wear
or breakage, see your authorized Scag service center for
belt adjustment.
All drive belts and cutter deck belts are spring loaded and
self-tensioning. The belts should be checked periodically
for proper alignment and wear.
WARNING:
Before removing any guards, shut the
engine off and remove the ignition key.
6.4 BELT ADJUSTMENT
-NOTE-
If after making the adjustment as outlined in step
2A, the machine creeps forward or backward, the
neutral adjustment must be made as described on
page 21.
6.3 THROTTLE CONTROL AND CHOKE
ADJUSTMENTS
These adjustments must be performed by your Scag
dealer to ensure proper and efficient running of the
engine. Should either need adjustment, contact your
authorized Scag service center.
