1. A control system for an agricultural toolbar drawn across a ground surface by a tractor, comprising:
a wheel coupled to the toolbar and engaging the ground surface; an actuator having an actuator pressure, said actuator being coupled to the toolbar, said actuator being disposed to modify a ground force between said wheel and the ground surface, said ground force being related to said actuator pressure; a fluid control system, said fluid control system being in fluid communication with said actuator, said fluid control system being operable to control said actuator pressure; and a controller in electrical communication with said fluid control system, wherein said controller is operable to send a command signal to the fluid control system, said command signal corresponding to a desired pressure, and wherein said fluid control system is operable to modify said actuator pressure in response to said command signal such that said actuator pressure corresponds to said desired pressure, and wherein said fluid control system is operable to maintain said actuator pressure at said desired pressure.
