Checking the Mower Deck
Front-to-Rear Pitch
1. Adjust the tire pressure in the rear tires to specifications;
refer to Drive System Maintenance (page 28) .
2. Position one blade front-to-rear. Measure at A and B
locations from a level surface to the cutting edge of
the blade tips (Figure 56).
3. The mower blade should be a 1/4 inch (6 mm) lower
in front at A than in the rear at B. Rotate blades and
repeat for other blades. If it is not correct, proceed to
Changing the Deck Front-to-Rear Pitch.

corresponding side that needs adjustment.
2. Adjust the caster spacer.
3. Recheck the front-to-rear pitch and side to side leveling
of the cutting unit.

Matching Height of Cut

2. Set the height-of-cut to the 4 inch (101.6 mm) position
following the height-of-cut decal.
3. With the machine on level surface, position one blade
