Abstract: A grain bin sweep is adapted to be assembled within a grain bin. The sweep comprises an auger assembly including a shield and an auger; and a tractor frame assembly comprising a frame first part and a frame second part. The sweep components are sized to fit through a small access opening to a grain bin and to then be assembled together within the grain bin. Additionally, the assembly of the grain bin sweep is accomplished using simple hand tools, such as wrenches, screwdrivers, etc. No welding, drilling or other fabrication is required to assemble the parts or components together to form the sweep.
