6.6 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.

6.7 CUTTER DECK ADJUSTMENTS

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 top of the
cutter deck to the floor. Next check the distance from the
top 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:
1. On the front LH side of the cutter deck locate the
cutter deck level adjusting bracket. See Figure 6-5.

2. Loosen the two (2) elastic stop nuts. Adjust the bolt
up or down on the adjustment bracket to adjust
the cutter deck until the distance from the top of
the cutter deck to the floor is the same as the
measurement on the RH side of the machine.
3. Tighten the two (2) elastic stop nuts to secure the
cutter deck in the proper position.
CUTTER DECK PITCH
The pitch of the cutter deck should be equal between
the front and rear of the cutter deck for proper cutting
performance. To check for proper deck pitch, be sure
that the mower is on a flat, level surface and the tires are
properly inflated.
Check the distance from the top of the cutter deck to the
floor at the rear RH side of the cutter deck directly behind
the cutter deck hanging chains. Next check the distance
from the top of the cutter deck to the floor at the front
RH side of the cutter deck directly in front of the cutter
deck hanging chains. The measurement at the front of the
cutter deck should be the same as the rear of the deck.
Make these measurements at the LH side of the cutter
deck also. If the measurement at the front of the deck is
not the same, the cutter deck pitch must be adjusted as
follows:
1. Loosen the jam nut on both adjusting rods. See
Figure 6-6.

2. Using an adjustable jaw pliers, turn the adjusting
rods on the non-threaded portion of the rod until the
deck is equal front to back on both the RH and the
LH side of the cutter deck. Tighten both lock nuts.
