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.
• Measure height from bottom edge of
mower to ground level at front corners
of mower. Distance "A" on both sides
of mower should be the same.
• 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 3/16".
• Recheck measurements after adjust-
ing.

FRONT-TO-BACK ADJUSTMENT

both front links equally so mower will stay

mower housing should be adjusted so
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 "P directly in front of
and behind the mandrel at bottom edge
of mower housing as shown.
• Before making any necessary adjust-
ments, check that both front plate 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 housing,
loosen nut "G" on both front links an
equal number of turns.
• When distance "P is 1/8" to 1/2" lower
at front than rear, tighten nut "H"
against trunnion on both front links.
• To raise front of mower housing, loosen
nut "H" from trunnion on both front links.
Tighten nut "G" on both front links an
equal number of turns.
• When distance =P is 1/8" to 1/2" lower
at front than rear, tighten nut "H"
against trunnion on both front links.
