Draper header having flexible cutterbar with pivotable support arms

摘要

A harvesting header having a flexible cutterbar assembly utilizes draper belts behind the cutterbar assembly to gently consolidate the severed crop materials and deliver them to a point of discharge and delivery, such as to the feederhouse of a combine harvester. The cutterbar assembly is supported by pivotable support arms such that it is operable to flex along the length thereof in response to changes in terrain as the header is advanced. One embodiment has draper assemblies and a central conveyor fixed relative to the flexible cutterbar assembly, while another has the draper assemblies and central conveyer flexible with the cutterbar assembly.
