Abstract
A grain combine according to the present invention includes a header having two sickles which extend on opposite sides of the combine for severing crop from a field, and two augers which extend on opposite sides of the combine for moving crop inward to central section of the combine. A centerline drive mechanical power transfer means directly connects to the two sickles and two augers at a point intermediate of the two sickles and two augers. A feeder has two conveyors, one located above the other, for transporting crop from the header to a primary threshing rotor. The two conveyors converge towards an aft end of the feeder to compress the crop therebetween. A perforated plate is provided beneath the aft end of the feeder for separating prethreshed grain from the crop. The prethreshed grain is passed through the perforated plate, onto a prethreshed grain conveyor and transported to a sieve section. The feeder passes the crop into the combine and through a cover plate having two apertures for passing the crop to opposite sides of a threshing rotor. The cover plate further has rearward facing bars. An impeller is mounted to the forward end of the threshing rotor and includes forward facing rasp bars which press the crop into the cover plate and the rearward facing bars mounted to an aft end of the cover plate.
