A mobile spreader having a main frame, a tank mounted on the main frame for receiving manure or other fertilizer material, and a ground engaging wheel assembly mounted on the main frame for supporting the tank. A pair of augers rotatably mounted in the tank for conveying material received in the tank to a discharge area where an opening is provided in the tank. An expeller assembly, also mounted on the main frame, receives material conveyed to the discharge area and discharges it from the tank as it is transported over a field. The pair of augers consist of a first auger having a tubular element with continuous flighting extending therefrom, and a second auger mounted parallel and adjacent the first auger. The second auger also has a tubular element. Interrupted flighting elements extends from the tubular element of the second auger to aggressively engage clumpy material and break it up into particles small enough to be transferred to the discharge area by the augers.
