ABSTRACT:
A center drive portable auger system for transporting particulate material. The auger includes an auger tube having a feed end and a discharge end, an auger drive shaft within the auger tube, and an auger flighting mounted to the auger drive shaft for transporting particulate material from the feed end to the discharge end of the auger tube. A gear box is positioned adjacent an external surface of the auger tube between the discharge end and the feed end for center driving the auger flighting. Since the central gear is external to the auger tube it does not restrict the flow of the particulate material within the auger tube, does not leak oil into the particulate material, and runs cooler than the internal gear boxes due to less friction during operation. A drive linkage operates between the gear box and the auger drive shaft for driving the auger flighting.
