Abstract

A method for clearing obstructions in a silo having a reciprocating frame uses an obstruction clearance mode. The method includes driving at least one frame in a reciprocal motion across a silo floor until sensing an indication that at least one frame has encountered an obstruction. Upon sensing the indication of obstruction, an obstruction clearance mode is initiated in an attempt to clear the obstruction.
