ABSTRACT:
A harvesting machine comprising a transversely extending threshold mechanism having a threshing cylinder cooperable with a threshing concave for threshing a layer of crop material fed therebetween and a separating mechanism having a separator rotor cooperable with a separator housing including a separator concave and disposed parallel to the threshing mechanism. Crop layer dividing means are foreseen on the separator rotor for dividing the layer of crop material received from the threshing mechanism into two portions. Separator means extend lengthwise of the separator rotor and are arranged spirally to convey said portions of the layer received from the threshing mechanism around said rotor in opposite directions to the opposite ends of the separating mechanism while submitting the crop material to a separating action.
