6.12.6 Header Angle
Header (or cutterbar) angle can be varied from
0–5° below horizontal with the mechanical
center-link, and 0–8° below horizontal with the
hydraulic center-link.
Choose an angle that maximizes performance
for your crop and field conditions.
A flatter angle provides better clearance in stony
conditions, while a steeper angle is required in
down crops for better lifting action.
DANGER
Stop engine, and remove key from ignition
before leaving Operator's seat for any
reason. A child or even a pet could engage
an idling machine.
6.12.6.1 Mechanical Adjustment (if equipped)
a. Lower header so that cutter bar is resting on the
ground.
b. Loosen nut (A).
c. To DECREASE (flatten) header angle, rotate the
turnbuckle sleeve (B) so that the turnbuckle
decreases in length.
d. To INCREASE (steepen) header angle, rotate
the turnbuckle sleeve (B) so that the turnbuckle
increases in length.
e. Snug up nut (A), but do not over-tighten.
A slight tap with a small hammer is sufficient.
f. Check cutting height, and adjust if required.
g. Check header float, and adjust if required. Refer
to Section 6.12.1 Header Float.
6.12.6.2 Hydraulic Adjustment (if equipped)
The header angle can be adjusted from the
tractor without shutting down the mower
conditioner.
a. To DECREASE (flatten) header angle, operate
tractor hydraulic control so that cylinder (C)
retracts, moving the gauge (D) toward the
GREEN zone.
b. To INCREASE (steepen) header angle, operate
tractor hydraulic control so that cylinder (C)
extends, moving the gauge (D) toward the RED
zone.
