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 65 or Figure 66). For 36 inch mower
decks use Figure 66.
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.

To raise the front of the deck, loosen jam nut and
rotate the front pin clockwise (Figure 67).
3.
To lower the front of the deck, loosen jam nut and
rotate the front pin counter clockwise (Figure 67).
4.
Position the blades front-to-rear. Measure at C and D
locations (Figure 65) from a level surface to the cutting
edge of the blades.
5.
Check the side-to-side leveling of the cutting unit.
