Abstract: The feeder of a combine has at least one rotatable cam and hook, rotatable about a common axis. The cam is arranged to gradually reduce the distance between the feeder and the header by rotating the cam away from the header and the hook is arranged to grip a bar located on the header as the cam is being rotated away from the header, thereby securing the header to the feeder. A coupling mechanism automatically establishes a hydraulic and/or electric coupling between the feeder and the header, through the reduction of the distance between feeder and header.

Abstract: The present invention relates to an agricultural machine such as a combine harvester. The machine comprises a feeder (1) such as a straw elevator, and a detachable header (2). The feeder comprises at least one rotatable cam (15) and a hook (16), rotatable about a common axis (14). The cam is arranged to gradually reduce the distance between the feeder and the header by rotating the cam (15) away from the header and the hook is arranged to grip a bar or pin (18) located on the header as the cam is being rotated away from the header, thereby securing the header to the feeder. An agricultural machine according to the invention further is equipped with a coupling mechanism (20) for automatically establishing a hydraulic and/or electric coupling between the feeder and the header, the coupling being actuated through the reduction of the distance between feeder and header.
