Wing Deck Leveling
Refer to Figure 2-3:
Each wing section will need adjusting if wing top is not
level with center deck top when wings are unfolded.
1.
With tractor hydraulics, lower the wings down. Refer
to
on page 26 for instructions on how
to lower the wing.
2.
Pull cutter straight forward six to ten feet to allow
outer wing wheels to properly align themselves.
3.
Check wing tops to see if they are level with the top of
the center deck. If the 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 higher
than the center
deck, loosen jam nut (#1) & rotate turnbuckle (#2)
clockwise to lower outer wing edge until wing is
level. Tighten jam nut (#1) to the correct torque
when level.
b.
If outer wing edge is lower
than the center deck,
loosen jam nut (#1) and rotate turnbuckle (#2)
counterclockwise to raise outer wing edge until
wing is level. Tighten jam nut (#1) to the correct
torque when level.

Cutting Height Adjustment
Refer to Figure 2-4:
1.
At the cutting site, unfold wings and raise center deck
fully up with lift cylinder.
2.
Place tractor gear selector in park or set park brake,
shut off tractor, and remove key before dismounting
from tractor.

Clockwise Rotation Shown
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.
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.
4.
Start tractor and engage blades. See instructions for
5.
Using tractor control lever, adjust cutter to the desired
cutting height and then travel forward for
approximately 20 to 50 feet.
6.
Stop tractor, disengage PTO, place tractor gear
selector in park or set park brake, shut off tractor,
remove key, and wait for blades to come to a
complete stop before dismounting from tractor.
7.
Measure height of cut grass/material. This distance
is the cutting height. If this height is acceptable,
continue with step 8. If this height is unacceptable,
repeat steps 4 to 7 until desired cutting height is
achieved.
8.
Select required size and number of stroke control
spacers (#2) that will fit on the center hydraulic
cylinder rod. The following spacers are available.
•
Two 1" spacers
•
One 1 1/4" spacer
•
One 1 1/2" spacer
•
One 1 3/4" spacer
9.
Return to the 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.
10. Return to tractor and lower cutter against stroke
control spacers. Recheck cutting height using
steps 4 to 7 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.
11. Keep remaining spacers with tractor for field
adjustments.
