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 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 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.
•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.
