摘要： A hydraulic system and earth-moving vehicle employing the hydraulic system are disclosed. The hydraulic system may include a first hydraulic cylinder and a second hydraulic cylinder, first and second hydraulic pumps and control valves to modulate provision of hydraulic fluid and pressure from the first and second hydraulic pumps to the first and second hydraulic cylinders as appropriate for the task being performed. If the task is digging with the earth moving vehicle, the first and second cylinders may be associated with tilting and lifting, respectively, and the control valves may be oriented so as to make each pump dedicated to one of the cylinders, and if demand is not being met, to then diminish power to the drivetrain to allow the tilting and lifting to be performed. The combiner may or may not be open during this time. The task is not digging, a combiner valve can be opened to allow for cross-flow between the pumps and the cylinders.
