Installing the Mower Deck (Figure 18)
1. Slide mower deck under unit.
2. Connect 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 Remove PTO Belt on
page 18).
5. Level mower deck (See Leveling the Mower Blades on
page 19).
Leveling the Mower Blades
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 in. (7.62 cm) cutting height.
2. Shut off engine. Engage parking brake. Remove the
ignition key.
NOTE: Place blocks under the bottom edge of the deck, not
under the reinforcement bar welded along deck face.
3. Place blocks at each corner of the deck to support the
weight of the deck.
4. Turn the blades so the blade ends point left to right across
the width of the deck.

5. Measure the distance between the ground and cutting edge
of the blade on the left blade (Left position in Figure 19) and
on the right blade (Right position in Figure 19). Distances
should be within 3/16 in. (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 20).
6. After deck is level side to side, check the deck front to back
pitch.
7. Turn the blades so the blade ends point front to back as
shown in Figure 19.
8. Measure the distance between the ground and the cutting
edge of the middle blade at the front of the deck (Front
position in Figure 19) and between the ground the cutting
edge of the left and right blades at the rear of the deck
(Rear position in Figure 19).
9. The cutting edge at the front of the deck (Front position in
Figure 19) should be 1/8 in. (3.18 mm) lower than the
cutting edges at the rear of the deck (Rear position in
Figure 19).
10. If measurements are out of range, raise the low side of the
deck using the height adjusters on the deck lift brackets
(see Figure 20). 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.
11. Remove the blocks from under the deck.
