7.12.3 HEADER ANGLE
Header angle is the angle between the drapers
and the ground, and is adjustable to
accommodate crop conditions and/or soil type.
Guard angle is the similar to header angle which
is the angle between the guard upper surface and
the ground.
Refer to illustration.
Flatter header angles are recommended for
normal crop conditions and for stony ground
because it minimizes sickle section breakage,
and reduces soil scooping or build-up at the
cutterbar in wet conditions.
Steeper angles are recommended in “downed”
crops for better lifting action, or for cutting close
to the ground in hay for example. Refer to
Section 7.12.10 Reel Tine Pitch and Section
7.12.9 Reel Fore-Aft Position for adjustment
details.
Header angle also affects the type of windrow
that is laid. Refer to Section 7.15 WINDROW
TYPES. Choose an angle that maximizes
performance for your crop and field conditions.
The following table summarizes the adjustment

7.12.3.1 Angle Adjustment
The header angle is varied by adjusting the
length of the top center-link (mechanical or
hydraulic) between the windrower and the
header.
Refer to “Header Angle in your Windrower
Operator’s Manual for adjustment details.
