Zusammenfassung:A hydraulic system is disclosed. The hydraulic system may have a unidirectional variable displacement first pump, a first hydraulic actuator connected to the first pump via a closed-loop first circuit, a unidirectional variable displacement second pump, and a second hydraulic actuator connected to the second pump via a closed-loop second circuit. The hydraulic system may also have a third pump selectively connectable in closed-loop manner to the first or second circuits, and a first valve disposed between the first hydraulic actuator and the first pump and configured to selectively direct fluid from the first circuit to the second and third pumps.
