Level Mower Deck
See Figure 45.
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.
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
IMPORTANT:
Side-to-side deck heights MUST
remain 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
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.
ADJUST CLUTCH
NOTICE:
Adjust clutch every 500 hours or once per
season if used less than 500 hours.
See Figure 46.
If clutch operates incorrectly or sounds abnormal,
check the gap at the three inspection slots.
Check Clutch
1. Place unit in service position. See
Service
Position
on page 17.
2. Measure gap between the armature and
rotor:
•
A 0.4 mm – 0.5 mm (0.016" – 0.020")
feeler gauge should fit between the
armature and rotor and make slight
contact with each.
3. Repeat measurements for remaining
inspection slots.
4. If gap is within range, no adjustment is
needed.
