tracked combine

Problem addressed/functional need Small scale threshing and cleaning equipment is not easily available in the United States. Older combines have threshing cylinders that are often prone to plugging in weedy conditions - the axial flow design does not have "choke points" that are as vulnerable to plugging because the clearances and threshing area in general, is larger. This documentation is intended to spark new low cost approaches to small scale combine harvesting equipment.
