2. Raise the low side of deck:
a. Loosen jam nuts against deck-leveling
links.
b. Turn adjustment bolts clockwise.
c. Measure distance between the
ground
and cutting edges of left and
right
blades. Continue adjustment if
necessary.
d. Tighten jam nuts against deck-leveling
links.
Adjust Blade Pitch
NOTICE: Side-to-side deck heights MUST remain
even after completing pitch
adjustment.
NOTICE: Pitching the front of the blades lower than
the rear provides a balance between cut quality and
the power needed to cut grass. Certain cutting
conditions require the deck rear to be pitched lower
than the front. Positioning the deck this way requires
more engine power but can provide better cut
quality.
1. Increase forward pitch:
2. Loosen jam nuts against all deck-leveling
links.
3. Turn front adjustment bolts
counterclockwise to lower deck front.
4. Turn rear adjustment bolts clockwise
to
raise deck rear.
5. Check adjustment. See
Check Blade Level
and Pitch
on page 31.
6. Tighten jam nuts against deck-leveling
links.
7. Decrease forward pitch:
a. Loosen jam nuts against all deck-
leveling links.
b. Turn front adjustment bolts clockwise
to raise deck front.
c. Turn rear adjustment bolts
counterclockwise to lower deck rear.
d. Check adjustment. See
Check Blade
Level and Pitch
on page 31.
e. Tighten jam nuts against deck-leveling
links.
ADJUST CLUTCH
NOTICE: Adjust clutch every 500 hours or once per
season if used less than 500 hours.
See Figure 42.
If clutch operates incorrectly or sounds abnormal,
check the gap at the three inspection slots.
