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.degree. 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.
