  • Patent number: 8286410
    Abstract: The non-row sensitive corn harvesting unit utilizes a tine wheel tilted to have tines that extend forwardly and downwardly into a side region of a stalk receiving area bounded by a row divider and which move along an upward and rearward trajectory toward a moving stalk handling element bounding an inlet of a stalk processing or picking channel, for pushing stalks toward the path of the handling element, such that the stalk will be grasped and carried into the channel, providing enhanced non-row sensitivity as well as handling of downed stalks. A companion tine wheel can be provided on the opposite side of the receiving area and function in the same manner.

  • Patent number: 7908836
    Abstract: The draper canvas of the header includes a strip of a resilient material that stands outwardly and forwardly of a front edge thereof and has an outer barrier surface, an inner barrier surface, and a front barrier surface received and contained in structure of a cutter bar and a front draper support plate having a plurality of barrier elements in face-to-face closely spaced relation with the barrier surfaces to form a multiple sided barrier interface between the cutter bar and draper fabric for excluding cut crop from the interior of the header. The strip runs within the container structure with minimal contact to reduce friction and wear.

  • Publication number: 20100083629
    Abstract: A flexible cutterbar support apparatus with integral adjustable torsional preload mechanism for connecting a cutterbar support arm to a header frame for upward and downward movement. The mechanism includes a first element connected to the support arm and extending about a second element configured for connection to the frame, and at least one resilient biasing element disposed between the first element and the second element and biasable by generation of a torsional loading condition between the first and second elements for applying a preload force therebetween. A preload adjusting mechanism in connection with at least one of the first element and the second element is operable for selectably adjusting the biasing of the at least one resilient biasing element in a manner for adjusting the preload force. The preload mechanism is also operable for damping vibrations emanating from the cutterbar, and can be used in cooperation with apparatus for damping the up and down movements thereof.
