If the cut is uneven, the mower may need leveling.

Unequal or improper tire pressure may also cause an

uneven cut. See CHECK TiRE PRESSURE.

1. Turn the blades front-to-back as shown in Figure 36.

Measure the distance from the ground to front tip of

center blade, and from ground to rear tips of left hand

and right hand blades (Figures 36 & 40). Front tips

should be 1/8"-1/4" (3-6 mm) higher than rear tips. If

not, proceed to step 2.

2. To raise or lower the front of mower deck, loosen lock

nut (A, Figure 40 inset) and turn eccentric nut (B).

3. Recheck measurement before tightening lock nut (A)

against bracket.
