  • Combine harvester with secondary cutter
    Patent number: 5433065
    Abstract: A conventional header of a combine is modified by the addition of a second sickle knife positioned rearwardly of the pan of the header. The second sickle knife is mounted on a bar which is connected to a pair of arms extending under the pan to a forward end pivotally mounted just behind the conventional sickle knife of the header. The arms and the second sickle knife can thus pivot upwardly and downwardly and are mounted on suspension springs carried on the frame of the header. A simple drive from the conventional shaft of the header is connected through a belt to a drive wobble box carried on the second sickle knife at a position partway along its length.

  • Harvesting machine with twin headers
    Patent number: 4715172
    Abstract: A harvesting machine particularly a swather comprises a frame carrying twin headers across the front of the frame and abutting centrally of the frame. The headers are mounted on pivot couplings arranged at respective front corners of the frame and of a type which allows the header to rotate through ninety degrees to a position along side the frame while at the same time causing the header to twist abut a longitudinal axis so that when it reaches a transport position along side the frame it is also raised. The movement from field transport position can be obtained by driving ground wheels at the outer ends of the headers. The reels can be moved longitudinally of the headers to accommodate pivotal movement of the headers caused by variations in field height.
