A combine harvester threshing drum threshing bar includes a rigid, integral, unitary threshing fixture having a leading edge and an opposed trailing end, an upstream face and an opposed downstream face formed with an oblique crop deflecting surface, a threshing side and an opposed threshing drum emplacement side. The threshing side includes a trailing threshing face formed toward the trailing end of the threshing fixture, and an inclined leading threshing face extending from the trailing threshing face to the leading edge, and which cooperates with the threshing drum emplacement side and the upstream and downstream faces of the threshing fixture at the leading edge to form a wedge in the threshing fixture. Crop threshing grooves are formed in the trailing threshing face of the top threshing side of the threshing fixture, which extend from the trailing end to the leading threshing face of the threshing fixture. |
