SERVICE AND ADJUSTMENTS

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 3of this manual).

If tires are over or under!nflated, you will not properly adjust

your mower.

SIDE-TO-SIDE ADJUSTMENT (See Figs. 20 and 21)

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: Each full turn of adjustment nut will change mower
height about 1/8".

Recheck measurements after adjusting.

tance “D” directly in front and behind the mandrel at bottom

edge of mower housing as shown.
