Abstract
A portable thrasher includes a housing with an interior, a mouth for passing crop heads into the interior, a grain discharge opening and a chaffe discharge opening. A thrashing assembly includes a primer mover mounted on the housing, a generally cylindrical flail subassembly driven by the prime mover and an oscillating sieve panel separating the housing interior into an upper, chaffee compartment and a lower, grain compartment.
