OPERATION
HEADER ANGLE
The header angle can be varied within these ranges:
Measured at Guards: 3.5 ° to 9.1° (cutterbar on ground).
Measured at Drapers: 14 ° to 19.6° (cutterbar on ground).
Achievable angles may vary depending on combine face plate angle.
IMPORTANT: The flattest header angles are recommended for normal conditions. A flatter header angle
reduces sickle section breakage and reduces soil scooping or build-up at the cutterbar in wet conditions. Use a
steeper angle to cut very close to the ground, or in down crop for better lifting action.
Header angle is varied by adjusting the length of the top link (mechanical or hydraulic) between adapter and
header. See "Header Angle" in Combine Adapter Operator's Manual for adjustment details.
DRAPER SPEED
Draper speed affects the orientation of stalks in the delivered crop. See Combine Adapter Operator's Manual
for adjustment details.
