A hydraulic system has gravitional load energy recuperation by opening a recuperation piloted valve with a pilot pressure supplied by a hydraulic pump so as to drive a recuperation hydraulic motor with a source of fluid pressurized by gravity from the load. The recuperation hydraulic motor drives the mechanical drive train of the prime mover that drives the pump that supplies the load, and other pumps that supply other loads.
