6.10 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 dealer for belt
adjustment.
6.11 CUTTER DECK ADJUSTMENTS
Due to many conditions that exist, it is difficult to suggest a
setting that will work for every lawn. However, two
adjustments should be made on the cutter deck to ensure
proper grass cutting: DECK LEVEL AND PITCH.
-NOTE-
Before checking for proper cutter deck adjust-
ments, check that all tires are inflated to the
correct pressure.
DECK LEVEL is the adjustment to level the deck side-to-
side. For proper blade cutting, the deck should be level.
To check for level, place the mower on a flat, level surface.
On the right side of the deck, measure from the ground to
the bottom of the cutter deck (Figure 6-7). Then, take a
measurement on the left side of the deck. Both measurements
should be equal. If different, adjust the deck to level.

Figure 6-7 Measuring Height of Deck
To level the deck, loosen the adjusting nut (Figure 6-8) and
lift or lower the deck until the left side measurement equals
the right side measurement. Tighten the adjusting nut.

PITCH is the adjustment to angle the blades from rear to
front. For proper grass cutting, the blades should be angled
forward. To check proper blade pitch, place the mower on
a flat, level surface. Measure the distance from the ground
to the rear of the mower deck ("X", Figure 6-9). Then,
measure on both sides of the mower deck the distance from
the ground to the front of the deck ("Y"). The front should
be 1/4 inch lower than the rear. If not correct, adjust the
pitch.
