MOWER DECK LEVELING

Perform these adjustments on a flat level surface.

SIDE-TO-SIDE LEVELING

1.With the mower installed, place the rider on a smooth, level surface such as a concrete floor. Turn the front wheels so they are straight.

2.Check for bent blades and replace if necessary.

3.Place the mower cutting height pin in the 4th hole from the bottom (see insert, Figure 33). Arrange the

outside mower blades so that they are pointing from side-to-side (Figure 31).

4.Measure the distance between the outside tips of each blade and the ground (Figures 31 & 32). If there is more than 1/8” (3mm) difference between the measurements on each side, proceed to step

5.If the difference is 1/8” (3mm) or less, proceed to step 6.

5.Use the rear leveling links (B, Figure 30) to adjust the side-to-side leveling of the deck. Repeat step

4if necessary.

6.Arrange the blades so they face front-to-back (Figure 34).

7.Measure the distance from the ground to the front tip of the center blade, and from the ground to rear tips of left-hand and right-hand blades (Figures 32 & 34). The front tip of the center blade should be 1/4" (6mm) higher than rear tips of left-hand and right-hand blades. If not, proceed with steps 8 - 11.

8.Check the length of the hanging rods. The rear (D, Figure 33) should be 15” (38,1cm) and is not adjusted. To adjust the pitch of the mower deck, adjust the front leveling nuts only.

9.Loosen the front lock nuts (E, Figure 33).

10.Turn the leveling nuts (A, Figure 33) counter- clockwise to lower the front of mower deck. Turn the nuts clockwise to raise the front of the mower. Make adjustments in small increments, trying to keep tension on both leveling nuts.

11.Tighten the front lock nuts (E).

12.Re-check the blade measurement then repeat steps 7-11 as necessary.
