ABSTRACT:
A device for crushing stubble comprising a rotatable crushing element supported by a frame. The frame is coupled by a pivotable connection to a drive mechanism which moves the device in a predefined direction across the stubble. The pivotable connection allows the crushing element to pivot about an axis substantially parallel to the predefined direction of motion so that substantial contact is maintained with the ground, thereby maximizing the extent of crushing. Limited vertical movement of the crushing element is permitted by a suspension mechanism.
