Abstract

See full text

A trailed agricultural implement is disclosed. The trailed agricultural implement includes a hydraulically-driven pump for moving a fluid at an actual fluid rate. An electro-hydraulic valve is configured to regulate an implement hydraulic pressure to the hydraulically-driven pump. The hydraulically-driven pump regulates the actual fluid rate. The electro-hydraulic valve is configured to receive a vehicle hydraulic pressure. The electro-hydraulic valve communicates with a vehicle load sense system. The load sense system senses the implement hydraulic pressure and communicates with a vehicle hydraulic pump. The vehicle hydraulic pump adjusts the vehicle hydraulic pressure to correspond to the implement hydraulic pressure.
