Adjusting Cutterbar Angle

Figure 3.73: Cutterbar Angle
Header angle (A) adjustment ranges from 0 to 8° 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 downed crops for better lifting action.
Check the float after significantly adjusting the header angle
because the adjustments affect the header float due to shifting
the header center of gravity. Refer to your windrower
operator
’
s manual for instructions.
NOTE:
An angle of 3 to 5° on the HPT display is suitable for most
conditions. At steep header angles (7 to 10°) the cut pattern of
the discs will become apparent, leaving a variation in stubble
height between discs.
3.7.3
Header Float
The M1240 float is completely adjustable from the cab through the Harvest Performance Tracker (HPT).
The header float feature allows the header to closely follow ground contours and respond quickly to sudden changes or
obstacles. The float setting is ideal when the cutterbar is on the ground with minimal bouncing, scooping, or pushing soil.
IMPORTANT:
•
Set header float as light as possible
—
without excessive bouncing
—
to avoid frequent breakage of knife components,
scooping soil, or soil build-up at the cutterbar in wet conditions.
•
Avoid excessive bouncing (resulting in a ragged cut) by operating at a slower ground speed when the float setting
is light.
•
Install applicable header options (crop dividers, etc.) before setting header float.
•
Adjust the float when adding or removing optional attachments that affect the weight of the header.
•
Changing header angle affects the float. Check the float after making appropriate changes to header angle for crop type
and conditions, field conditions, and speed settings.
For instructions on setting and adjusting the header float, refer to your windrower operator
’
s manual.
