6.17.9 Header Angle
Header (or guard) angle can be varied from 8° to
16° below horizontal. 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.
6.17.9.1 Header Angle: Self-Propelled
Header angle can be hydraulically adjusted from
the cab using hydraulic cylinder (A), without
shutting down the windrower. To adjust angle,
refer to your self-propelled windrower
operator’s manual.
6.17.9.2 Header Angle: Pull-Type
6.17.9.2.1 Mechanical Adjustment (if equipped)
a. Lower header so that cutter bar is resting on
the ground.
b. Loosen nut (B).
c. To decrease (flatten) header angle , rotate the
turnbuckle sleeve (C) so that the turnbuckle
decreases in length.
d. To increase (steepen) header angle , rotate the
turnbuckle sleeve (C) so that the turnbuckle
increases in length.
e. Snug up nut (B), but do NOT over-tighten. A
slight tap with a small hammer is sufficient.
f. Check cutting height, and adjust if required.
Refer to Section 6.17.8 Cutting Height .
g. Check header float, and adjust if required. Refer
to Section 6.17.10 Header Flotation .
6.17.9.2.2 Hydraulic Adjustment (if equipped)
The header angle can be adjusted from the
tractor, without shutting down the windrower/
mower conditioner.
a. To decrease (flatten) header angle , operate
tractor hydraulic control so that cylinder retracts,
decreasing the number of holes in the gauge (D)
that are exposed.
b. To increase (steepen) header angle , operate
tractor hydraulic control so that cylinder extends,
increasing the number of holes in the gauge that
are exposed.
