FRONT-TO-BACK ADJUSTMENT
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 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 "F" directly in front of
and behind the mandrel at bottom edge of
mower housing as shown.
• Before making any necessary adjust-
ments, 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 mower housing, loosen
nut "G" on both front links an equal num-
ber 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. The two front
links must remain equal in length.
• When distance "F" is 1/8" to 1/2" lower
at front than rear, tighten nut "H" against
trunnion on both front links.
NOTE: Each full turn of nut "G" will
change distance "F" by approximately
3/8".
• Recheck side-to-side adjustment.
