FAILURE TO MATCH VALVE TO TRACTOR
HYDRAULIC SYSTEM BY USING INCOR-
RECT PLUG WILL CAUSE DAMAGE TO
TRACTOR.
2-3 PITCH ADJUSTMENT
The pitch of the cutter (front to rear) is controlled by
adjusting the linkage rods (Figure 2-4). Shortening
the linkage rod assemblies will raise the front of
the cutter. Lengthening the linkage rod assem-
blies will lower the front of the cutter. The pitch ad-
justment is primarily for compensating for the different
height of tractor drawbar. As described in the follow-
ing, it can also be used to alter the cutting perform-
ance. Note that operating the cutter at any pitch other
than parallel to the ground will produce a slightly un-
even cut.
CAUTION
Figure 2-4 Linkage Rod Adjustment Turnbuckles

If you are cutting in dense material, operating cutter
with the rear slightly higher than the front will allow an
increased volume of cut material to exit from under-
neath cutter. This will decrease the cutter horsepower
requirements.
TO AVOID SERIOUS INJURY OR DEATH:
OPERATING CUTTER WITH REAR LOW-
ERED EXCESSIVELY WILL RESULT IN AN
UNEVEN CUT AND COULD CAUSE RAPID
BLADE, SKID AND DRIVELINE WEAR AND
POSSIBLY CAUSE STRUCTURAL FAILURES
IN THE WING HINGE AREA.
TO AVOID SERIOUS INJURY OR DEATH:
DO NOT PLACE HANDS, FEET OR OTHER
PARTS OF THE BODY UNDER CUTTER
WHILE MAKING ADJUSTMENTS. NEVER
MAKE ADJUSTMENTS WITH CUTTER OPER-
ATING.
IMPORTANT
NEVER ADJUST THE TURNBUCKLE SO THAT
THE THREADED END OF ANY ROD IS NOT FULLY
ENGAGED IN THE TURNBUCKLE.
WARNING
WARNING
The wings should be adjusted before use. To check the
wings for levelness, measure from the top of the center unit
hinge tube (“B” & “C”) to the ground at the front and rear of
the unit. Measure from the flat (horizontal) area extending
from the gearbox to the side band at “A” to the ground. This
dimension should be between the measurements taken at
the center section hinge tube. Repeat for both wing sec-
tions. Measurements taken at “A” for both wings should be
the same.

LEVELING THE CUTTER
To check the attitude of the unit for side to side level and
front to real level, the following locations should be used:
Place cutter on a flat area with the wings unfolded and the
wing cylinder control valve in float position.
To check the front to rear levelnes, measure from the top
of the center section hinge tube to the ground at the front
of the unit at ”B” and the rear of the unit at “C”.
