A powertrain for a work machine, including at least one electric motor, an electric energy store, a multi-stage manual transmission, a heating circuit, and a cooling circuit. The at least one electric motor is configured to provide a mechanical input power. The manual transmission is configured to convert the mechanical input power and provide it as mechanical output power. The energy store is configured to supply the at least one electric motor and the heating circuit with electric power. The heating circuit is configured to provide a heating fluid for heating the energy store. The cooling circuit is configured to provide a cooling fluid for cooling and lubricating the manual transmission. The heating circuit and the cooling circuit are coupled via a heat exchanger and have only a single joint cooling device.
