Section 6
If at full speed the mower pulls left, it is an indication 2.
that the right wheel is turning faster than the left
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 RH steering
control rod. Rotate the control rod to lengthen 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.
- NOTe -
If after making the adjustment as outlined in step
2A, the machine creeps forward or backward,
perform the neutral adjustment. See Neutral
Adjustment on page 23.

engine. Should either need adjustment, contact your
authorized Scag service center.
BELT ADJUSTMENT 6.4
WARNING
Before removing any guards, shut the engine off
and remove the ignition key.
All drive belts are spring loaded and self-tensioning,
however after the first 2, 4, 8 and 10 hours of operation,
the belts should be checked for proper alignment and
wear. Thereafter, check the belts after every 40 hours of
operation or weekly, whichever occurs first.
BELT ALIGNMENT 6.5
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.
CUTTER DECK ADJUSTMENTS 6.6
Cutter deck level, pitch and height are set at the factory.
However, if these adjustments should ever need to be
made, the following procedures will aid in obtaining the
proper cutter deck adjustment.
- NOTe -
Before proceeding with the cutter deck adjustments,
be sure that all tires are properly inflated.
CUTTER DECK LEvEL
The cutter deck should be level from side-to-side for
proper cutting performance. To check for level, be sure
that the mower is on a flat, level surface, the tires are
properly inflated and the cutter deck is set at the most
common cutting height that you will use. On the RH side
of the machine, check the distance from the bottom of the
cutter deck to the floor. Next check the distance from the
bottom of the cutter deck to the floor on the LH side of
the machine. Both measurements should be the same. If
the two measurements are different, the cutter deck level
must be adjusted as follows:
On the front LH side of the cutter deck locate the 1.
cutter deck level adjusting bracket. See Figure 6-4.
