Cutting on Ground
Cutting height will vary depending on crop type, crop conditions, cutting conditions, etc.
Cutting on the ground is performed with the header fully lowered and the cutterbar on the ground. The orientation of the
knife and knife guards relative to the ground (header angle) is controlled by the skid shoes and the center-link
—

NOT
controlled by the header lift cylinders. The skid shoes and center-link allow you to adjust to field conditions and maximize
the amount of material cut while reducing damage to the knife caused by stones and debris.
The header float system compensates for variations in ground contour to prevent the cutterbar from pushing into the
ground or leaving uncut crop.
Refer to the following for additional information:
