IMPORTANT: DECK MUST BE LEVEL SIDE-TO-SIDE. IF THE
FOLLOWING FRONT-TO-BACKADJUSTMENT IS NECESSARY,

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