ABSTRACT:
A front foldable farm implement and hopper-feeding auger comprising an elongated hopper-supporting frame in three separable sections in end-to-end relation. A drawbar is secured to and transversely extends from the central portion of the intermediate section. First means pivotally connects the opposite ends of this central portion to the adjacent ends of the outboard sections, respectively, whereby the outboard sections may be pivoted between a first position in which the three sections are aligned and a second position in which the outboard sections are generally parallel to the drawbar. A plurality of hoppers is carried by the sections. An elongated tubular conveyor in two separable length portions is carried by the two outboard sections, respectively, these length portions being disposed above and in feeding registry with the hoppers. Further, the conveyor extends parallel to the frame sections when the outboard sections are in the first position. The conveyor length portions include two tubular elements which receive two rotary augers, respectively, the adjacent ends of the tubular elements being joined and the augers drivably connected to rotate in unison when the outboard sections are in the first position. The tubular elements are separated and the augers disconnected when the outboard sections are moved to the second position. The tubular elements have material-discharge openings in registry with the hoppers, respectively. A feed port on the outboard end of one conveyor length portion only is provided for introducing flowable granular material into the conveyor which conveys such material through both length portions and to all of the hoppers when the outboard sections are in the first position.
