ABSTRACT:
A harvester includes a mobile vehicle with a forward vertically adjustable header that includes a mechanism for stripping grain from a standing crop as the machine advances while leaving the stem of the crop attached to the soil. The stripping mechanism including a pair of axially transverse vertically offset brush-type rotors having randomly spaced radial bristles, the upper rotor being disposed slightly forwardly of the lower and being driven so that its lower surface moves rearwardly in close proximity to the rearwardly moving upper surface of the lower roller that is driven in the opposite direction from the first rotor. The grain heads on most of the standing crop is disposed between the axes of the rotors, and the grain is stripped as the heads move into the bite between the rotors. A front blower directs a stream of air toward the bite and a rear blower directs a stream of air upwardly to the rear of the lower rotor, to create a lower pressure zone behind the rotors that assist the feeding of stripping material to a collector bin on the vehicle.
