ABSTRACT:
A harvesting machine has a mobile main frame with a forwarding harvesting header that includes an axially transverse stripping rotor that is rotated with the front side moving upwardly to engage the grain bearing heads of a standing crop and separate the grain from the crop by impact while leaving the stem attached to the field. The impact with the stripping elements projects the grain rearwardly on the header to a crop collecting mechanism, which conveys it to a grain cleaning means in the body of the harvesting machine. An upper drum-type rotor is mounted on the header above and parallel to the stripping rotor and is provided with vanes and an arcuate hood, the upper rotor being rotated in the opposite direction from the lower rotor and generating an air flow between the drum and the hood that exits from the hood in a downward and rearward direction to assist in directing the grain heads into the stripping rotor and to convey the stripped grain rearwardly to the crop collecting mechanism.
