4. Remove the mower mounting pins

connecting the mower mounting arms to

the deck.

5. Slide mower deck out from under unit.

Installing the Mower Deck (Figure 22)

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 Replacing

Mower Belts on page 25).

5. Level mower deck (See Leveling the

Mower Deck on page 27).

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 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 23)

and on the right blade (Right position in

Figure 23). 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 24).

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 23.

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 23) and

between the ground the cutting edge of

the left and right blades at the rear of the

deck (Rear position in Figure 23).

9. The cutting edge at the front of the deck

(Front position in Figure 23) should be

1/8 in. (3.18 mm) lower than the cutting

edges at the rear of the deck (Rear

position in Figure 23).

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 24). 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.
