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" section of this
manual). 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 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.
• When distance "D" is 1/8" to 1/2"
lower at front than rear, tighten nuts "F"
against trunnion on both front links.
• To raise front of mower, loosen nut "F"
from trunnion on both front links. Tighten
nut "E" on both front links an equal num-
ber of turns. The two front links must
remain equal in length.
• When distance "D" is 1/8" to 1/2" lower
at front than rear, tighten nut "F" against
trunnion on both front links.
• Recheck side-to-side adjustment.
