See Figure 50.
1. Lower the high side of deck:
a. Loosen jam nuts against deck-
leveling links.
b. Turn adjustment bolts
counterclockwise.
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.
2. Raise the low side of deck:
a. Loosen jam nuts against deck-
leveling links.
b. Turn adjustment bolts clockwise.

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.

container before adding fuel.
a. Add fuel stabilizer (see Service Parts
on page 17) or equivalent according
to manufacturer's instructions to the
fuel tank and any fuel containers with
remaining fuel.

repair of any defect in workmanship, and repair or replacement of any defective part. Ariens Company shall
not be liable for incidental, special, or consequential damages (including lost profits). Some states do not

for particular purpose, or any other implied warranty, applies to Ariens Company, then any such implied
