ABSTRACT:
A harvesting machine includes a feed mechanism configured for being driven in a forward direction to feed crops into the harvesting machine and a reverse drive mechanism for driving the feed mechanism in a reverse direction. The reverse drive mechanism includes a cam surface, a plurality of cam engagement members, and a plurality of pistons connected to the engagement members. One of the cam surface and the plurality of cam engagement members is operatively coupled to the feed mechanism. Controlled movement of the pistons in a first direction forces the cam engagement members into engagement with the cam surface to drive the feed mechanism in the reverse direction. Movement of each of the pistons in a second direction allows the feed mechanism to rotate in the forward direction.
