FRONT-TO-BACK ADJUSTMENT (See Figs. 21 and 22)
IMPORTANT: DECK MUST BE LEVEL SIDE-TO-SIDE. IF
THE FOLLOWING FRONT-TO-BACK ADJUSTMENT IS
NECESSARY, BE SURE TO ADJUST BOTH FRONT LINKS
EQUALLY SO MOWER WILL STAY LEVEL SIDE-TO-
SIDE.
To obtain the best cutting results, the mower housing should
be adjusted so that the front is approximately 1/8" to 1/2"
lower than the rear when the mower is in its highest position.

Raise mower to its highest position.
•
At the midpoint of both sides of mower, measure height
from bottom edge of mower to ground. Distance “A” on
both sides of mower should be the same or within 1/4"
of each other.

side of mower only.
•
To raise one side of mower, tighten lift link adjustment
nut on that side.
•
