A cleanout configuration is provided for a grain compartment on a harvesting apparatus. The grain compartment has walls that form a trough, and a vertically arranged auger that is supported on an auger casting located in a sump at a bottom of the trough. Wall portions, in the form of a unitary casting with the auger casting are adjacent to the auger casting and comprise cleanout openings covered by removable covers. The openings are in a grate pattern. The unitary casting can be a bridge member, which supports all, or a substantial amount of the weight of the unitary casting and the auger.
