  • Patent number: 4353201
    Abstract: Our transfer mechanism is attached to the front of a conventional combine. The transfer mechanism includes a number of longitudinally spaced rows of laterally spaced curved teeth or tines that move rearwardly and upwardly so that the tines of each row successively engage a growing or standing crop, such as pinto beans or field peas, lifting the crop sufficiently so that the cutter bar of the combine effectively severs the crop adjacent the surface of the ground. Continued rearward and upward movement of the tines, while still engaging the severed crop, transfers the crop to a more elevated location adjacent the auger. When the tines reach the auger, the shaft on which those particular tines are mounted is angularly rotated so as to release or dump the severed crop onto a curved floor beneath the auger. The auger moves the cut crop laterally and then rearwardly into the threshing portion of the combine.
