Adjust Blade Pitch
IMPORTANT: Side-to-side deck heights
MUST remain level even after completing
pitch adjustment.
IMPORTANT: 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:
a. Loosen jam nuts against all deck-
leveling links.
b. Turn front adjustment bolts
counterclockwise to lower deck front.
c. Turn rear adjustment bolts clockwise
to raise deck rear.
d. Check adjustment. See Check Blade
Level and Pitch on page 30.
e. Tighten jam nuts against deck-
leveling links.
2. 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 30.
e. Tighten jam nuts against deck-
leveling links.
