Checking and Adjusting Header Float
The header is equipped with a suspension system that fl oats the header over the ground to compensate for
ridges, trenches, and other variations in ground contour. If the header fl oat is not set properly, it may cause the
cutterbar to push into the ground or leave uncut crop. This procedure describes how to check header fl oat and
adjust to the factory-recommended settings.
