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. A crop hold down is vertically pivotally mounted in the vicinity of each of the augers and is downwardly biased so as to aid the positive engagement of crop with the augers thereby resulting in a continuous, even inward flow of crop.
