Abstract:
1. A flail rotor head attachment for attachment to a harvesting machine having crop residue processing elements, a power source and including an input opening for receiving crop residue into a harvesting machine, the attachment comprising: a frame structure for operatively coupling the attachment to the front portion of a harvesting machine; a housing having an exit opening for positioning in alignment with the input opening of a harvesting machine; a flail rotor mounted on said frame structure, said flail rotor including a plurality of cutting elements for picking up and chopping crop residue from a field; an auger mounted on the frame structure for receiving crop residue from the flail rotor, the auger having at least two flightings positioned in opposite directions for funneling crop residue towards the exit opening of the housing for delivery to the input opening of a harvesting machine; a rake positioned between the flail rotor and the auger, said rake including a plurality of tines for further engaging the crop residue and for facilitating the funneling of the crop residue from the flail rotor to the auger; and a drive mechanism coupled to said flail rotor, said auger and said rake for rotating said flail rotor and said rake in the same direction relative to each other and for rotating said auger in an opposite direction relative to said flail rotor and said rake.
