TO LEVEL MOWER HOUSING
Adjust the mower while tractor is parked on
level ground or driveway. Make sure tires are
properly inflated (See side of tire for proper
PSI). 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 '_' 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".
