ABSTRACT:
A header for an agricultural machine having a cutterbar, an auger and a rotatable reel, the reel having a main axis of rotation around which the reel is rotated in one direction, crop-engaging members being rotatably mounted on the reel around respective pivot axes disposed around the main shaft, is disclosed wherein inclination control means including steering means positioned eccentrically of the main axis are operable, during rotation of the reel in said one direction, to rotate the crop-engaging members around the respective pivot axes in the opposite direction so as to maintain the crop-engaging members at a fixed positional inclination relative to the horizontal so that the free ends of the crop-engaging members define a circularly shaped locus. Drive means are associated with the steering means for oscillating said steering means during rotation of the reel such that the crop-engaging members equally are oscillated back-and-forth around their respective further pivot axes on the reel and the locus defined by the path of movement of the free ends of the crop-engaging members deviates from said circular shape. Means are also provided for neutralizing said drive means associated with the steering means so that the reel may be operated with either a circular or a non-circular locus.
