3.8.2 Adjusting Cutterbar Angle

Figure 3.104: Cutterbar Angle
The header angle (A) adjustment ranges from 0 to 8 degrees
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.
3.8.3 Header Float
The M1 Series, M155, and M155 E4 windrowers have different float adjustments. Although they both have float springs, the
M1 Series are completely adjustable from the cab through the Harvest Performance Tracker (HPT), the M155 and M155 E4
have coarse adjustment done at the spring drawbolt and fine adjustment done through the Cab Display Module (CDM) in
the windrower cab.
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.
