Superior Manufacturing offers a grain bin unloading system with unload speeds up to 6,000 bushels per hour. The unloading system features a 9-inch, under-bin grain auger inside an 11-inch U-Trough. In a traditional system, the auger forces grain through a 10-inch tube. The grain gets compacted and pressed against the inside of the tube and is often damaged as a result. By comparison, the U-Trough has no sidewalls and there is more space between the auger and the trough. With its 11-inch diameter, the U-Trough also has greater capacity. Bulk grain free flows over the auger for fast unloading speeds.
