Abstract
In a drive system for the threshing cylinder of a combine harvester, a conventional infinitely variable V-belt drive, is combined with a two-speed final drive assembly. In the final drive assembly, an epicyclic gear train is housed within the body of a driven sheave carried on the cylinder shaft. A sun gear of the gear train is controllable externally of the sheave body and may be pinned for rotation with the sheave in a direct drive mode, or nonrotatably secured relative to the combine body for a cylinder speed reducing mode. The combine cylinder speed is therefore infinitely variable within, selectively, either an upper range or a lower range.
