TO LEVEL MOWER HOUSING

Adjust the mower while tractor is parked on level ground or driveway. Make sure tires are properly infl ated (See “PRODUCT SPECIFICATIONS” section of this manual). If tires are over or underinfl ated, you will not properly adjust your mower.

SIDE-TO-SIDE ADJUSTMENT (See Figs. 19 and 20)

•Raise mower to its highest position.

•Measure height from bottom edge of mower to ground level at front corners of mower. Distance “A” on both sides of mower should be the same.

•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 3/16".

•Recheck measurements after adjusting.

IMPORTANT: DECK MUST BE LEVEL SIDE-TO-SIDE. IF THE FOLLOWING FRONT-TO-BACK ADJUSTMENT IS NECESSARY, BE SURE TO ADJUST BOTH FRONT LINKS EQUALLY SO MOWER WILL STAY LEVEL SIDE-TO-SIDE.

CAUTION: Blades are sharp. Protect your hands with gloves and/or wrap blade with heavy cloth.

Check adjustment on right side of tractor. Position any blade so the tip is pointing straight forward. Measure distance "B" at front and rear tip of the blade.

•Before making any necessary adjustments, check that both front plate 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 blade, loosen nut “C” on both front links an equal number of turns.

NOTE: Each full turn of nut “C” will change distance. “B” by approximately 3/16".

•When distance “B” is 1/8" to 1/2" lower at front than rear, tighten nut “D” against trunnion on both front links.

•To raise front of blade, loosen nut “D” from trunnion on both front links. Tighten nut “C” on both front links an equal number of turns.The two front links must remain equal in length.

•When distance “B” is 1/8" to 1/2" lower at front than rear, tighten nut “D” against trunnion on both front links.
