These engines were built primarily as self propelled power plants, mainly for farm use. They would be used for driving threshing machines, sawmills and other plant by means of a belt from the flywheel, and could be used for winching by use of a wire rope on a winding drum fitted to the rear axle. They were also used for hauling threshing equipment from farm to farm. The coming of more powerful diesel tractors after the last war, and later the combine harvester, saw the end of commercial work for this type of engine by the early 1950's.
