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".
