Abstract: Systems, methods and apparatus for controlling the downforce applied to a row unit of an agricultural implement having multiple row units. A downpressure control device in fluid communication with a down chamber of the least one actuator maintains as a selected downpressure, any one of a continuous range of pressures in the downpressure chamber. A lift pressure control device in fluid communication with a lift chamber of the at least one actuator for controlling pressure in the lift chamber maintains as a selected lift pressure, any one of a continuous range of pressures in the lift chamber.
