Abstract: The invention relates to adding of auxiliary apparatus to a conventional or standard hydrostatic steering system of the type in which a steering wheel controlled metering device controls the application of pressurized fluid to hydraulic motor means which operates the rod system of the wheels to be steered. The auxiliary apparatus allows a conventional metering system of relatively small size and capacity to be utilized for heavier vehicles than a system of a particular size or capacity could otherwise be used for. The auxiliary apparatus includes a valve which is operable in response to the pressure differential across the motor ports of the meter of the conventional system to provide greater operating forces for turning the wheels of the vehicle.
