  • Patent number: 6314708
    Abstract: A stripper for lifting crop off flat rigid tines of a rotary conveyor is molded of ultra high molecular weight polyethylene. The stripper is oval-shaped in side view and is constructed of identical halves which each include a pair of spaced apart, parallel side walls that have marginal portions defined by rims which have a thickness greater than that of the side walls. An intermediate, concave wall extends between and is joined to the bases of the rims, which have a height measured from the respective base that is approximately twice the thickness of the associated side walls.

  • Patent number: 6279304
    Abstract: A large round baler includes a crop pick-up assembly which is wider than the baling chamber and equipped with right- and left-hand stub augers for centering the crop for delivery through the inlet of the baling chamber. In order to prevent the augers from compressing crop against crop feeding tines located between the inner ends of the stub augers, crop lifters are mounted to inner end portions of each of the stub augers. The stub augers are each double flight augers with the flights being offset 180° from each other. The crop lifters each include first and second lifter plates respectively associated with the first and second flights, the lifter plates each having a first end fixed to the auger core and being curved outwardly from the core to the outer periphery of the associated flight.

  • Patent number: 5848523
    Abstract: A large round baler includes a crop feed arrangement for taking up crop deposited on the ground and for delivering it to the inlet of the baling chamber of the baler. The baling chamber has a width less than that of a pick-up forming a forward portion of the crop feed arrangement and the arrangement includes a pair of augers respectively mounted at its opposite sides for narrowing the flow of crop to a width matching that of the baling chamber. These augers are mounted on a shaft also used for supporting a plurality of dogs, of a rotary crop conveying apparatus, in laterally spaced relationship to each other along the shaft. The shaft is located below the conveying surface of the crop feed arrangement. The dogs are in the form of diametrically opposite pairs of tines which sweep the crop in an overshot fashion to move the crop towards the baling chamber inlet.
