TO LEVEL MOWER HOUSING
Adjust the mower while tractor is parked
on level ground or driveway. Make sure
tires are properly inflated (See "PROD-
UCT SPECIFICATIONS"). If tires are
over or underinflated, 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
adjustment on one side of mower only.
• To raise one side of mower, tighten lilt
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".

FRONT-TO-BACK ADJUSTM ENT
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.
Check adjustment on right side of tractor.
Measure distance "D" directly in front
and behind the mandrel at bottom edge
of mower housing as shown.
• Before making any necessary adjust-
ments, check that both front links are
equal in length. Both links should be
approximately 10-3/8".
• If links are not equal in length, adjust
one link to same length as other link.
• To lower front of mower loosen nut "E"
on both front links an equal number of
turns.
