3. Install mower lift links on the mower lift
arms in the same holes they were
removed from.
4. Install PTO mower belt (See Replacing
Mower Belts on page 34).
5. Raise the deck to the transport position
and connect the lift assist springs to the
lift arms.
6. Level mower deck (See Leveling the
Mower Deck on page 38).
Leveling the Mower Deck
These adjustments should be made on a
level surface with the tires inflated to the
correct air pressure.
Check Blade Level and Pitch
1. Raise mower deck to a 3-1/2" (8.9 cm)
cutting height.
2. Shut off engine. Engage parking brake.
Remove the ignition key.
3. Turn the blades so the blade ends point
left to right across the width of the deck.
4. Measure the distance between the
ground and cutting edge of the blade on
the left blade (Left position in Figure 32)
and on the right blade (Right position in
Figure 32). Distances should be within
3/16" (4.7 mm). If they are not, raise the
low side of the deck using the height
adjusters on the deck lift brackets (see
Figure 33).
5. After deck is level side to side, check the
deck front to back pitch.
6. Turn the blades so the blade ends point
front to back as shown in Figure 32.
7. Measure the distance between the
ground and the cutting edge of the
middle blade at the front of the deck
(Front position in Figure 32) and
between the ground the cutting edge of
the left and right blades at the rear of the
deck (Rear position in Figure 32).
8. The cutting edge at the front of the deck
(Front position in Figure 32) should be
1/8" (3.2 mm) lower than the cutting
edges at the rear of the deck (Rear
position in Figure 32).
9. If measurements are out of range, raise
the low side of the deck using the height
adjusters on the deck lift brackets (see
Figure 33). Be sure to raise the deck
evenly to keep the deck level side to
side.
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 to be pitched with the rear of the
blades lower than the front. Heeling the deck
this way requires more engine power but can
provide better cut quality.

Adjust Blade Height
Level and pitch the mower with the height
adjusters (3) on each deck lift bracket
(Figure 33).
1. Turn the adjustment bolt (1) clockwise to
lower the deck or counterclockwise to
raise the deck.
2. Adjust all four corners of the deck to
desired pitch, ensuring that deck is even
side to side and front to back.
