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 36 .
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 76).
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.

3. Front height-of-cut pins
2. To raise the front of the deck, loosen jam nut
and rotate the front pin clockwise (Figure 77).
3. To lower the front of the deck, loosen jam
nut and rotate the front pin counter clockwise
(Figure 77).
4. Position the blades front-to-rear. Measure at
C and D locations (Figure 76) from a level
surface to the cutting edge of the blades.
5. Check the side-to-side leveling of the cutting
unit.
6. Tighten the jam nuts (Figure 77).
