ABSTRACT:
In the harvesting of a crop there is always a portion of the crop that is lost as a result of the combine harvesting process. The present device is attached to the underside of the combine and is arranged to pick up seeds and short crop missed by the first sweep of the combine. The device provides a fan arrangement within a housing carried adjacent the surface of the ground. The vacuum device picks up the seeds and short crop left behind by the normal pick up action of the combine. The present invention increases the yield of the crop, thereby making harvesting more cost efficient.
