Header Angle - MacDon A30-S Operator's Manual

6.17.8 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.
6.17.8.1 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
Operator's Manual.
6.17.8.2 Header Angle: Pull-Type
6.17.8.2.1 Mechanical Adjustment (if equipped)
a. Lower header so that cutter bar is resting on the
ground.
B
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.

SECTION 6 OPERATION
A
Self-Propelled Windrower
C
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 6.17.7 Cutting Height.
g. Check header float, and adjust if required. Refer
to Section 6.17.9 Header Flotation.
6.17.8.2.2 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.
