TO LEVEL MOWERHOUSING
Adjust the mower while tractor is parked
on level ground or driveway. Make sure
tires areproperly inflated (See "PROD-
UCT SPECIFICATIONS" section of this
manual). If tires are over or underin-
flated, you will not properly adjust your
mower.
SIDE-TO-SIDE ADJUSTMENT
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 ad-
justment 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.

ment is necessary, be sure to adjust both
front links equally so mower will stay level

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.

behind the mandrel at bottom edge of

Before making any necessary adjust-
ments, check that both front links are
equal in length.
If links are not equal in length, adjust
one link to same length as other link.
