Abstract
A silo unloader has an auger collector for moving material to an impeller operable to discharge material from a tower silo. A sprocket and endless chain secured to a transition assembly mounted on the impeller drives the collector around the silo wall. Wheels on the outer end of the collector and wheels on a biased arm on the inner end of the frame stabilize the unloader in the silo. A stop pivotally connected to the collector limits its backward movement by lifting the collector from the material.
