TO
LEVEL MOWER HOUSING
Adjust the mower while tractor is parked on
level ground or driveway. Make sure tires
are properly inflated (See sides of tire for
proper PSI). 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 '_' on both
sides of mower should be the same or
within 1/4" of each other.
• If adjustment is necessary, make adjust-
ment 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.
FRONT-TO-BACK ADJUSTMENT

IMPORTANT: Deck must be level side-to
side. If the following front-to-back adjust-
ment 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 trac-
tor. 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.
• 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.
