  • Patent number: 7222804
    Abstract: The invention concerns an arrangement for the adjustment of the position of a shearbar with respect to knives of a chopper assembly. The arrangement includes a first adjusting drive to position the first end of the shearbar at a predetermined first spacing from the knives and a second adjusting drive to position the second end of the shearbar with respect to the knives until a spacing measurement arrangement indicates that the spacing between the shearbar and the knives is less than a threshold value. An analogous procedure is applied to the first adjusting drive. On the basis of the measurement values the shearbar is brought into a position that corresponds to a desired gap between the shearbar and the knives. Each of the first spacing and the second spacing are greater than the desired gap between the shearbar and the knives.

  • 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.
