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 man-

ual). If tires are over or underinflated, you will not properly adjust your mower.

SIDE-TO-SIDE ADJUSTMENT

•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 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".

•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.

•When distance "D" is 1/8" to 1/2" lower

at front than rear, tighten nut "F" against trunnion on both front links.

•Recheck side-to-side adjustment.

Adjustment

FRONT-TO-BACK ADJUSTMENT

IMPORTANT: Deck must be level side-to side. If the following front-to-back adjust- ment is necessary, be sure to adjust both

front links equally so mower will stay level side-to-side.

To obtain the best cutting results, the mower housing should be adjusted so that

the front is approximately 1/8" to 1/2" lower than the rear when the mower is in its

highest position.

Check adjustment on right side of trac- tor. Measure distance "D" directly in front and behind the mandrel at bottom edge of mower housing as shown.

•Before making any necessary adjust- ments, check that both front links are equal in length.

•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.
