Abstract
An apparatus for efficiently removing grain from a grain storage device, which uses a plurality of augers. An unloading auger is used to begin removal of grain from a grain storage device. As the amount of grain decreases, a proximity sensor sends an activation signal to a cross auger that rests horizontally on the bottom of the grain storage device. The cross auger will pull the remaining grain to the entry point of an unloading auger. The unloading auger then removes the grain from the grain storage device.
