Figure 42. Orient Blades Front-to-Back
Front To Back Leveling
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 42.
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 (Figure 42). Front tips should
be 1/8"-1/4" (3-6 mm) higher than rear tips. If not, pro­
ceed to Step 2.
2. The front hitch rod (A, Figure 43) is used to adjust
front-to-back leveling. To raise or lower the front of the
mower deck, loosen the two rear jam nuts (B) on both
sides of the front hitch rod (A). Adjust the front jam
nuts (C) on both sides of the front hitch rod (A) to
adjust the mower deck level. When adjusted correctly,
tighten the rear jam nuts (B) to lock the front hitch rod
in place.
