SERVICE AND ADJUSTMENTS

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” section of this manual). If tires are over or underinflated, you will not properly adjust your mower.

SIDE-TO-SIDE ADJUSTMENT (See Figs. 16 and 17)

•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: Three full turns of adjustment nut will change mower height about 1/8".

•Recheck measurements after adjusting.

• 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 1/8" to 1/2" lower at front than rear, tighten nuts “F” against trunnion on both front links.
