The wheel on a back-geared spins quickly, while a direct-stroke mill must turn slowly to build up the force to pump water. Self-oiling mills became popular in the 1920's. These windmills had an enclosed gearbox with an oil-bath that would lubricate the moving parts of the mill as the moved. This meant maintenance on these mills was minimal.
