Installing the Mower Deck
(Figure 27)
1. Slide mower deck under unit.
2. Connect rear mower mounting arms to
deck with mower mounting pins.
3. Install link chains on the mower lift arms
in the same holes they were removed
from.
4. Install PTO mower belt (See Replacing
Mower Belts on page 30).
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 34).
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 28)
and on the right blade (Right position in
Figure 28). 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 29).
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 28.
7. Measure the distance between the
ground and the cutting edge of the
3
middle blade at the front of the deck
(Front position in Figure 28) and
between the ground the cutting edge of
the left and right blades at the rear of the
deck (Rear position in Figure 28).
8. The cutting edge at the front of the deck
(Front position in Figure 28) should be
1/8" (3.18 mm) lower than the cutting
edges at the rear of the deck (Rear
position in Figure 28).
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 29). Be sure to raise the deck
evenly to keep the deck level side to
side.
NOTE: 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.
