A hydrostatic transmission includes a side having an upstream radial piston motor and a downstream radial piston motor. The motors are connected to each other in series via a connecting line. A flow control valve is configured to discharge pressure medium from the connecting line so that the downstream motor is only engaged in the event of a predetermined amount of slippage of the upstream motor. Each motor has at least two groups of working flanks. Each flank is configured to operatively interact with a high pressure, such that each motor has at least two transmission steps.
