1/4” higher than the front. If the rear blade tip is
lower or is more than 1/4” higher than the front,
proceed with adjustment.
a. Remove rear hanger chains.
b. Turn each hanger pivot the same number of
rotations on the eye-bolt to raise or lower the
rear of the deck. See Figure 4.8.
c. Reinstall rear hanger chains and measure
blade tips again.

levelness is obtained.
