Wing Deck Leveling
Each wing section will need adjusting if top surface of
wing is not level with top surface of center deck when
wings are unfolded.
1.
With tractor hydraulics, lower wings down. Refer to
on page 24 for instructions on how to
lower wings.
2. Pull cutter straight forward six to ten feet to allow
outer wing wheels to properly align themselves.
3. Check top of wings to see if they are level with the top
of the center deck. If outer edge of either wing is
higher or lower than the center deck, then that wing
should be leveled as follows:
a.
If outer wing edge is too high
, loosen nut (#1)
and rotate turnbuckle (#2) counterclockwise to
lower outer wing edge until wing is level. Tighten
nut (#1) against turnbuckle (#2) when level.
b.
If outer wing edge is too low
, loosen nut (#1)
and rotate turnbuckle (#2) clockwise to raise outer
wing edge until wing is level. Tighten
nut (#1) against turnbuckle (#2) when level.

DANGER
!
To avoid serious injury or death:
Do not attempt to add or remove stroke control spacers while
Rotary Cutter blades are turning. Cutter blades rotating at
high speeds cannot be seen and are close to the deck edge.
Body extremities can be cut off instantly.
1.
At the cutting site, unfold wings and raise center deck
fully up with lift cylinder.
2. Place tractor gear selector in park, set park brake,
shut off tractor, and remove key before dismounting
from tractor.

NOTE:
Make all cutting height adjustments in the
field using height of cut grass/material as a guide.
Do not measure blade height above ground as the
non-operating blade height will be different than the
operating blade height.
3. Verify rod end of hydraulic lift cylinder (#1) is pinned
in the upper hole when 29" aircraft tires are used and
lower hole when 21" laminated tires are used. See
“Lift Cylinder Mounting Position”
instructions to change cylinder mounting position.

4. Remove all stroke control spacers (#2) from center
hydraulic cylinder (#1) by spreading them apart at
the break line. Store spacers in a location they can be
retrieved.
5. Start tractor and engage blades. See instructions for
6. Using tractor control lever, adjust cutter to the desired
cutting height and then travel forward for
approximately 20 to 50 feet.
7.
Stop tractor, disengage power take-off, place tractor
gear selector in park, set park brake, shut off tractor,
remove key, and wait for blades to come to a
complete stop before dismounting from tractor.
8. Measure height of cut grass/material. This distance
is the cutting height. If this height is acceptable,
continue with step 9. If this height is unacceptable,
repeat steps 5 - 8 until desired cutting height is
achieved.
9. Select required number and size of stroke control
spacers (#2) that will fill the space on the center
hydraulic cylinder rod (#1).
10. Return to tractor and raise Rotary Cutter up again.
With tractor shut off and switch key removed, install
selected stroke control spacers on the center
hydraulic lift cylinder rod (#1).
11. Return to tractor and lower cutter against stroke
control spacers. Recheck cutting height using
steps 5 - 8 above. If needed, adjust size and quantity
of stroke control spacers until desired cutting height
is achieved.
Removing spacers lowers the cutting height and
adding spacers raises the cutting height.
12. Keep remaining spacers with tractor for field
adjustments.
