Figure 3.29: Center-Link
Set the header angle according to the type and condition of
crop and soil as follows:
•
Use shallower settings (A) (position
A
on the indicator) for
normal cutting conditions and wet soil to reduce soil buildup
at the cutterbar. Shallow angle settings also minimize damage
to the knife in stony fields.
•
Use steeper settings (D) (position
D
on the indicator) for
lodged crops and crops that are close to the ground such as
soybeans.

Figure 3.30: Guard Angles
The shallowest angle (A) (center-link fully retracted) produces
the highest stubble when cutting on the ground.
The steepest angle (D) (center-link fully extended) produces the
lowest stubble when cutting on the ground.
Choose an angle that maximizes performance for your crop and
field conditions. Refer to the table below for a summary of
adjustment ranges.

Adjusting Header Angle
Header angle can be adjusted using the center-link between the windrower and the header.
Refer to the windrower operator
’
s manual for adjustment details.
3.7.4
Reel Speed
Reel speed is one of the factors that determines how crop is moved from the cutterbar onto the drapers.
The reel performs best when it appears to be driven by the ground. It should move the cut crop evenly through the
cutterbar and onto the drapers without bunching and with minimal disturbance.
In standing crop, reel speed should be slightly higher than, or equal to, ground speed.
In flattened crop or crop that is leaning away from the cutterbar, the reel speed needs to be higher than the ground speed.
To achieve this, either increase the reel speed or decrease the ground speed.
Excessive shattering of grain heads or crop loss over the header backtube may indicate that the reel speed is too high.
Excessive reel speed also increases reel component wear and overloads the reel drive.
Slower reel speeds can be used with nine-bat reels, which is advantageous in shatter-prone crops.
Refer to for recommended reel speeds in specific crops and crop conditions.
