Abstract

In one aspect, a system for controlling the supply of hydraulic fluid to an implement may include a pump, a control valve coupled to the pump and first and second fluid lines provided in flow communication with output ports of the control valve. The system may also include a pressure control valve configured to regulate a pressure of the hydraulic fluid being supplied to the control valve such that the hydraulic fluid is supplied to the control valve at a first pressure for raising at least one ground-engaging component of the implement and a second pressure for lowering the ground-engaging component(s). Moreover, the system may include a bypass line in fluid communication with the pressure control valve such that fluid diverted through the bypass line actuates the pressure control valve to adjust the fluid pressure of the hydraulic fluid supplied to the control valve between the first and second pressures.
