TO LEVEL MOWERHOUSING

Adjust the mower while tractor is parked on level ground or driveway. Make sure tires areproperly inflated (See "PROD- UCT SPECIFICATIONS" section of this

manual). If tires are over or underin- flated, 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 ad- justment 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.

FRONT-TO-BACK ADJUSTMENT

IMPORTANT: Deck must be level side-to side. If the following front-to-backadjust- 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 tractor. 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.
