Mower Belt Replacement - Craftsman 107.28791 Operator's Manual

Figure 36. 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 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 33 & 36). Front tips
should be 1/8"-1/4" (3-6 mm) higher than rear tips. If
not, proceed to step 2.
2. The front mower hitch rod (A, Figure 37) is used to
adjust front-to-back leveling. To raise or lower the
front of mower deck, loosen the two rear jam nuts (B)
on both sides of the hitch rod (A). Adjust the front
jam nuts (C) on both sides of the hitch rod (A) to
adjust the deck level. When adjusted correctly,
tighten the rear jam nuts (B) to lock hitch rod in place.
