that the front is approximately 1/8" to 1/2"
lower than the rear when the mower is in
its highest position.

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.

• 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 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 adjust-
ing.
