3.7.2 Header Float
The header float system reduces the ground pressure at the cutterbar, allowing the header to more easily follow the
ground and quickly respond to sudden ground contour changes or obstacles.

Figure 3.33: Float Indicator
Header float is indicated on the CA25 float indicator (A).
The values 0 to 4 represent the force of the cutterbar on the
ground with 0 being the minimum and 4 being
the maximum.
The maximum force is determined by the tension on the
adapters adjustable float springs. The tension is factory-
set, but it can be changed to suit field and crop conditions.
Refer to Checking and Adjusting Header Float, page 59.
