2.Rotate the right and left mower blades until the ends of both mower blades are facing rearward (Figure 8).

NOTE: The rear blade cutting height should be 2-7/8 to 3 in. (7.3 to 7.6 cm) from rear edge of mower blades to the ground on both blades (Figure 8).

IMPORTANT: The distance from rear edge of mower blades to the ground MUST NOT exceed 3 in. (7.6 cm) (Figure 8).

3.Measure from rear edge of mower blades to the ground.

4.Perform steps 5 through 7 if the measurement is too high to too low on either side of mower deck.

5.Remove rear lift link and rear trunnion from mower deck and mower lift.

TO RAISE the mower deck, turn rear trunnion clockwise several turns.

TO LOWER the mower deck, turn rear trunnion counterclockwise several turns.

6.Install rear trunnion and rear lift link on mower deck and mower lift.

7.Check that the mower deck is level:

Rotate right and left mower blades to face side-to- side.

Measure outer edge of mower blades to ground. Measurement must be within 1/4 inch (6.35 mm).

If mower deck is not level, repeat steps 5 and 6.

If mower deck is level, record the distance from rear edge of mower blades to the ground and then adjust pitch of mower deck.

Adjust Pitch of Mower Deck

IMPORTANT: The mower blade end used to level the mower deck must be used to adjust the pitch of the mower deck.

1.Rotate the right and left mower blades 90 degrees until the end of the mower blade that was used to level the mower deck is facing forward (Figure 8).

NOTE: The front blade cutting height should be 1/16 - 1/4 inch (1.59 - 6.35 mm) lower than the rear blade cutting height.

2.Measure from front edge of right and left mower blades to the ground.

3.Subtract front blade cutting height measurement from rear blade cutting height measurement.

4.Perform steps 5 through 7 if the front blade cutting height is too high or too low on either side on either side of mower deck.

5.Remove front lift link and front trunnion from mower deck and mower lift (Figure 6).

TO RAISE the mower deck, turn front trunnion clockwise several turns.

TO LOWER the mower deck, turn front trunnion counterclockwise several turns.

6.Install front trunnion and front lift link on mower deck and mower lift.

7.Check mower deck pitch.

If mower deck pitch is not correct, repeat steps 2 through 6.

If mower deck pitch is correct, the adjustment is complete.

4.8 ADJUSTING ANTI-SCALP ROLLER

NOTE: The anti-scalp rollers are intended to prevent lawn scalping, not to control cutting height. All anti- scalp rollers should be set at the same height.
