SERVICE AND ADJUSTMENTS
FRONT-TO-BACK ADJUSTMENT (See Figs. 24 and 25)
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.
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 dis-
tance "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. Both links should be
approximately 10-3/8".
•
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.
