<p>A hydraulic system (72) is disclosed having first, second, and third pumps. The hydraulic system may also have a first actuator (26) connected to the first pump in closed-loop manner, a second actuator (32) connected to the second pump in closed-loop manner, and a third actuator (34). The hydraulic system may further have a selector valve (122) associated with the third pump, and a first switching valve (121) associated with the third pump and the third actuator. The first switching valve may be movable between a first position at which the third pump is connected to the third actuator in a closed- loop manner to move the third actuator in a first direction, a second position at which the third pump is connected to the third actuator in a closed-loop manner to move the third actuator in a second direction, and a third position at which the third pump is connected to the selector valve.</p> |
