Abstract
A harvesting machine comprising a transversely extending threshing 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 and being arranged spirally to convey portions of the layer of crop material received from the threshing mechanism towards each of its ends while submitting the crop material to a separating action. A rotary member with a plurality of beater means transversely spaced apart on the width thereof, is disposed between the threshing mechanism and the separating mechanism for orienting crop material in the layer of crop material received from the threshing mechanism generally lengthwise in the direction of movement of the layer. Crop layer dividing means are provided on the separator rotor for dividing the layer of crop material received from the rotary member into said portions prior to the spiral movement thereof in the separating mechanism.
