Abstract
A harvesting machine comprising a threshing mechanism, a transverse rotary separator mechanism having discharge outlets adjacent its opposite ends, and discharge channels in register with the discharge outlets leading to a common strawhood. The separator mechanism is arranged spirally to convey crop material received from the threshing mechanism toward each of its ends while submitting the crop material to a separating action and to forcefully eject crop material through said discharge outlets and through said discharge channels in the direction of the common strawhood. A crop material chopper device is associated with each discharge channel and is disposed out of the normal path of the crop materials through the respective discharge channel. A deflector device associated with each chopper device is adjustable between a position retracted from said normal path of the crop material and a further position across said normal path. The arrangement is such that in the former position of the deflector device, crop material forcefully issuing from the separating mechanism bypasses the associated chopper device in moving toward the strawhood and that in the latter position said crop materi…
