•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.

•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: Three full turns 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 raise front of mower, 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.

both front links are equal in length.

• If links are not equal in length, adjust one link to same

length as other link.
