BELT ALIGNMENT6.5
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 ADJUSTMENTS6.6
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 6.5)

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 bottom 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 bottom 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 equal to the measurement
at 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 equal, the cutter deck pitch must
be adjusted as follows:
Loosen the jam nut on both adjusting rods. (See
