Patent ID: 8631634

Claim:
An agricultural machine with an automatic coupling system comprising: a feeder that is attachable to a header the feeder comprising a lifting component that lifts up the header from the ground for an automatic coupling thereof to the feeder, the lifting component comprising a cradle that supports a beam of the header, the feeder further includes; a cam that is rotatable around an axis, the cam located lower than the cradle, and an actuating component that rotates the cam around the axis wherein the cam and the actuating component are configured to: maintain the header at a distance from the feeder, after the header has been lifted from the ground, by extending the cam towards a support surface of the header, reduce the distance between the feeder and the header, by rotating the cam away from the support surface of the header, the support surface being in contact with the cam during at least a part of a rotation thereof, the feeder further comprises one or more hooks, that are rotatable via the actuating component around the axis while maintaining a fixed relative position with respect to the cam, wherein to facilitate the automatic coupling between the header and the feeder the hooks rotate towards the header while the cam moves away from the support surface of the header, so that the hooks thereby grip a bar or pin located on the header, thereby securing the header to the feeder.
