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.
D1 Series draper headers perform best with minimum ground pressure under normal conditions. Readjust the float if
adding/removing optional attachments to the header that affect header weight.
5.6.1
Checking Header Float
If the header float is not set properly, it may cause the cutterbar to push into the ground or leave uncut crop. This
procedure describes how to check the header float.

Figure 5.10: Float Springs
Header float can be gauged by the length of threaded
portion (A) of the spring adjustment bolts.
The maximum force is determined by the tension on the float
module
’
s adjustable float springs (B). Float can be changed to
suit field and crop conditions and is dependent on what options
have been installed on the header.
The recommended float setting for cutting on the ground is
when there is approximately 34 kg (75 lb.) weight on each side
of the header at the cutterbar. Readjust as needed for the given
field conditions.
5.6.2
Adjusting Header Float
This procedure explains how to adjust the header float so that the header floats over the ground to compensate for ridges,
trenches, and other variations in ground contour.
If float adjustment is required, follow these steps:
