NW Washington | The "down front threshing" was a trademark of Gleaners and Curtiss Baldwin from their very beginning back in the 1920's. I am not all that sure it was an advantage as most grain is separated in the concave area of a regular conventional cylinder design and Gleaner had to convey all the threshed grain, straw and chaff up several feet with a raddle chain before the cleaning process got started. Plugging behind the cylinder can be another issue. No one ever copied the design. | |
