An agricultural vehicle system including a towing vehicle and an implement towed by the towing vehicle. The towing vehicle supplying pressurized hydraulic fluid to the implement. The implement includes a chassis, an electrical generation device carried by the chassis and a hydraulic flow control system. The electrical generation device has a hydraulically driven motor coupled to the pressurized hydraulic fluid. The hydraulic flow control system is configured to alter a flow of the hydraulic fluid to the motor and to maintain a speed of the motor, with the speed being dependent upon a configuration input defining a configuration of the implement to which the electrical generation device is coupled.
