Abstract: A method of controlling a hydraulic system includes providing fluid to a first actuator with a first pump via a first closed-loop circuit of a machine, and providing fluid to a second actuator with a second pump via a second closed-loop circuit of the machine. The method also includes providing fluid to a third actuator with a third pump via a third closed-loop circuit of the machine, and providing fluid to a fourth actuator with a fourth pump via a fourth closed-loop circuit of the machine. The method further includes forming a combined flow of fluid including fluid from the first circuit and fluid from at least one of the second, third, and fourth circuits, and directing the combined flow to the first actuator while providing fluid to the actuator of the at least one of the second, third, and fourth circuits.
