ABSTRACT:
A forage harvester row crop attachment including a main frame adapted to be attached to a field traversing forage harvester having a crop inlet. An auger, mounted on the main frame generally transverse to the direction of travel of the forage harvester, comprises a tube and flighting mounted on the tube for engaging the upper portion of standing row crops as the forage harvester traverses the field. A transverse cutting assembly, mounted below the auger, has cutting device for cutting the lower portion of standing row crops. Also mounted below the auger are elements for engaging the lower portion of the stalks in cooperation with the auger flighting under conditions where the auger is rotated in a direction that urges the crop material downwardly and inwardly. After the crop is cut it is urged rearwardly by the auger toward a crop outlet in the floor of the attachment adjacent the inlet in the harvester on which the attachment is mounted. Intermediate the crop engaging elements and the floor are crop grasping elements that cooperate with the auger to grasp the lower portion of the crop material before, during and after cutting takes place.
