FRONT-TO-BACK ADJUSTMENT
IMPORTANT: Deck must be level side-to
side. If the following front-to-back adjust-
ment 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 trac-
tor. Measure dis tance “D” directly in front
and behind the mandrel at bottom edge of
mower housing as shown.
Before making any necessary ad just -
ments, check that both front links are
equal in length.

TO LEVEL MOWER HOUSING
Adjust the mower while tractor is parked
on level ground or driveway. Make sure

UCT SPECIFICATIONS” section of this
man u al). If tires are over or underinfl ated,
you will not properly adjust your mower.
SIDE-TO-SIDE ADJUSTMENT
Raise mower to its highest position.
At the midpoint of both sides of mower,
measure height from bot tom edge of

sides of mower should be the same or
within 1/4" of each other.
If adjustment is necessary, make adjust-
ment on one side of mower only.
To raise one side of mower, tighten lift
link ad just ment nut on that side.
To lower one side of mower, loosen lift
link ad just ment nut on that side.
NOTE: Each full turn of adjustment nut
will change mower height about 1/8".
Recheck measurements after ad just ing.

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”
