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
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.
If clutch operates incorrectly or sounds
abnormal, check the gap at the three
inspection slots.
Check Clutch
1. Place unit in service position. See
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 measurement for remaining
inspection slots.
4. If gap is within range, no adjustment is
needed.
Adjust Clutch
1. Place unit in service position. See
2. Loosen adjustment nut until a
0.5 mm (0.020") feeler gauge fits between
armature and rotor.
3. Tighten adjustment nut until armature and
rotor make slight contact with feeler
gauge.
4. Repeat at remaining inspection slots.
NOTICE:
Air gap MUST be even at all
inspection slots.
