One or more techniques and/or systems are disclosed for a hydraulic system that is used with a vehicle hitch, to raise and lower an implement attached to the hitch. The system has a lifting side, that raises the hitch, and a downforce side that applies downward pressure. Hydraulic actuators are used to apply the up or down force using supply lines coupled to both sides. A downforce pressure control valve controls an amount of hydraulic pressure is supplied to the downforce side. A mode select valve is fluidly coupled to the downforce pressure control valve and is used to select hitch operation between a double acting hitch position, a single acting hitch position, and a neutral position. A work port check valve is between the downforce side and the mode select valve to stop the fluid from flowing back into the system when de-energized or in the neutral position.
