TO LEVEL MOWER HOUSING

Adjust the mower while tractor is parked on level ground or driveway. Make sure tires are properly inflated (See "PRODUCT SPECIFICATIONS" on page 3 of this manual). Iftires are over or underinflated, you will not properly adjust your mower.

SIDE-TO-SIDE ADJUSTMENT (See Figs. 22 and 23)

•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 adjusting.

•Before making any necessary adjustments, check that both front links are equal in length. Both links should be approximately 10-3/8".

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

•To lower front of mower loosen nut "E" on both front links an equal number of turns.

•When distance "D" is 1/4" to 3/4" 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.
