Abstract
An implement control system includes an automatic control valve assembly configured to utilize fluid from a supply conduit to cause a cylinder to raise a ground engaging tool relative to a soil surface and to utilize the fluid flow from the supply conduit to cause the cylinder to lower the ground engaging tool relative to the soil surface while an automatic control mode is active. The implement control system also includes a controller configured to control the automatic control valve assembly based on a position of the ground engaging tool relative to the soil surface to control the position of the ground engaging tool relative to the soil surface while the automatic control mode is active. The controller is also configured to deactivate the automatic control mode in response to fluid pressure within a first manual control conduit exceeding a threshold pressure.
