Abstract
A header for an agricultural machine including a support structure, a header frame, a floating cutterbar assembly, and a spring. The support structure may be adapted to mount the header to the agricultural machine. The header frame is pivotally coupled to the support structure. The floating cutterbar assembly is operatively coupled to the header frame and pivotally coupled to the support structure. The floating cutterbar assembly is moveable between a first position and a second position. The spring is coupled between the header frame and the floating cutterbar assembly for reducing a ground contact force on the cutterbar.

A header for an agricultural machine, the header comprising:
- a support structure adapted to mount the header to the agricultural machine;
- a header frame pivotally coupled to the support structure;
- a floating cutterbar assembly operatively coupled to the header frame and pivotally coupled to the support structure, wherein the floating cutterbar assembly is moveable between a first position and a second position;
- a spring coupled between the header frame and the floating cutterbar assembly for reducing a ground contact force on the cutterbar;
- and
- a support mechanism coupled to the support structure and operable to adjust a height of the header frame relative to the ground, wherein the support mechanism is pivotal relative to the support structure between a retracted position to lower the header frame and an extended position to raise the header frame.
