SERVICE AND ADJUSTMENTS

FRONT-TO-BACK ADJUSTMENT (See Figs. 22 and 23) -

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.

Check adjustment on right side of tractor. Measure distance “F” directly in front of and behind the mandrel at bottom edge of mower housing as shown.

•Before making any necessary adjustments, 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 housing, loosen nut “G” on both front links an equal number of turns.

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

•To raise front of mower housing, loosen nut “H” from trunnion on both front links. Tighten nut “G” on both front links an equal number of turns.

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