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 27) .
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 58).
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.

2. To raise the front of the deck, loosen jam nut and
rotate the front pin clockwise (Figure 59).
3. To lower the front of the deck, loosen jam nut and
rotate the front pin counter clockwise (Figure 59).
4. Position the blades front-to-rear. Measure at C and
D locations (Figure 59) 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 59).

Side-to-Side Height
1. Adjust the rear tire pressure to specifications; refer
to Drive System Maintenance (page 27) .
2. Position the blades side-to-side. Measure at C and
D locations from a level surface to the cutting edge
of blade tips (Figure 60).
3. The difference between measurements C and D
should be no more than 1/4 inch (6 mm).
