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 38. 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 38). 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 39) 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.
