Abstract

A crop conveying apparatus for laterally urging crop from outboard ends of a cutting header on an agricultural harvester toward an interior discharge zone for formation of a windrow or for feed to a subsequent crop processing apparatus. Helical flighting extending radially from a transversely disposed, rotatable central core defines a first profile for the auger apparatus adjacent each outboard end of the header and extending inwardly to a position near, but not co-extensive with the width of a crop discharge zone in the header. Auger flighting in the central portion of the header co-extensive with the width of the discharge zone opening features a variable profile that tapers from the first profile to a minimum profile centrally located between the side edges of the discharge zone opening to provide optimal movement of severed crop material into the discharge opening, resist entanglement and clogging of the crop material, and minimize the loss of seed from the crop stem.
