TO LEVEL MOWER HOUSING
Adjust the mower while tractor is parked on level ground or
driveway. Make sure tires are properly inflated (See
“PRODUCT SPECIFICATIONS” on page 3 of this manual).
If tires are over or underinflated, you will not properly adjust
your mower.
SIDE-TO-SIDE ADJUSTMENT (See Figs. 22 and 23)
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.
If adjustment is necessary, make adjustment on one
side of mower only.
To raise one side of mower, tighten lift link adjustment
nut on that side.
To lower one side of mower, loosen lift link adjustment
nut on that side.
NOTE: Three full turns of adjustment nut will change
mower height about 1/8".
Recheck measurements after adjusting.
