ABSTRACT:
The multi-stage crop termination system includes a main frame assembly connected to first and second roller frames. A first roller is installed in the first roller frame and a second roller is installed in the second roller frame. A compression frame extends between the main frame and the second roller frame so that a downwardly compression force is applied to the second roller. In the preferred embodiment, the first roller is a smooth drum and the second roller is a central cylindrical drum with a plurality of crimping bars extending outwardly from the drum. In operation, crops are flattened by the first roller and then crimped by the second roller. A pivot joint between the first roller frame and the second roller frame ensures that the second roller is able to maintain contact with the ground as the system traverses uneven terrain.
