An agricultural implement system is provided that includes an implement, and a fluid control unit configured to mount to a tow vehicle. The agricultural implement system also includes a depth control cylinder mounted to a frame of the implement and fluidly coupled to the fluid control unit. The depth control cylinder is configured to adjust a penetration depth of a ground engaging tool of the implement by varying a height of a ground engaging wheel. In addition, the agricultural implement system includes a sensor communicatively coupled to the fluid control unit and configured to output signals indicative of the penetration depth of the ground engaging tool. The fluid control unit is configured to automatically control fluid flow to the depth control cylinder based on the signals to maintain a user-selectable penetration depth.
