Springland UTL45 Transfer Auger **11" diameter u-trough compares to a 13" tradition round auger. "The UTL45 auger will unload your bins faster than ever." The Springland U-Trough design moves more material than traditional round tubes at the same horsepower with less chance of grain damage. When loading the u-trough fills to the top of lid allowing product to flow with little or no contact with the flighting. This innovation allows the augers to be used for all products from lentils, grains, and canola, to fertilizers. The design has the benefits of a traditional auger and conveyor combined. Another advantage of the u-trough design is that the UTL40 can be powered with a more economical gas engine to keep the price down on a high capacity auger.
