TO LEVEL MOWER HOUSING

Adjust the mower while tractor is parked

on level ground or driveway. Make sure

tires are properly inflated (See “PROD­

UCT SPECIFICATIONS”). If tires are
over or underinflated, you will not properly

adjust your mower.

SIDE-TO-SIDE ADJUSTMENT
• Raise mower to its highest position.
• Measure height from bottom of deck

curl to ground level at front comers of
mower. Distance “A” on both sides of
mower should be the same.

• If adjustment is necessary, make adjust­

ment on one side of mower only.

• To raise one side of mower, tighten lift

link adjustment nut on that side.

• To lower one side of mower, loosen lift

link adjustment nut on that side.

NOTE: Each full turn of adjustment nut
will change mower height about 3/16".

• Recheck measurements after adjusting.

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 the

front is approximately 1/8" to 1/2" lower
than the rear when the mower is in its

highest position.
Check acjjustment on right side of tractor.

Measure distance “P directly in front of
and behind the mandrel at bottom edge of
mower housing as shovwi.

• Before making any necessary adjust­

ments, check that both front finks 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
number of turns.

• When distance “P 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. .

• When distance “P 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 dim. “P by approximately 3/8“.
