TO LEVEL MOWER HOUSING
Adjust the mower while tractor is parked on
level ground or driveway. Make suretires are
properly inflated (See side 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.
When distance "D" is 1/8" to 1/2" lower
at front than rear, tighten nuts "F" against
trunnion on both front links.
• To raisefrontofmower, loosen nut"F"from
trunnion on both front links. Tighten nut
"E" on both front links an equal number
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.

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, checkthat both front links are equal
in length.
