abstract: a downforce controller for an agricultural implement having a double-acting hydraulic cylinder. the cylinder is configured to be coupled to an agricultural row and an agricultural toolbar for transmitting a net downforce between the agricultural toolbar and the agricultural row unit. a first pressure in the first chamber of the cylinder and a second pressure in the second chamber of the cylinder having counteracting effects on the net downforce. a manifold coupled to the cylinder is in fluid communication with the first chamber. a pressure control valve supported by the manifold is in fluid communication with the manifold and the first chamber abstract of the patent summary: "integrated implantation descending force control systems, methods and apparatus". The present invention relates to a downforce controller for an agricultural deployment having a double acting hydraulic cylinder. The cylinder is configured to be coupled to an agricultural row unit and an agricultural toolbar to transmit a net downward force between the agricultural toolbar and the agricultural row unit. a first pressure in the first cylinder chamber and a second pressure in the second cylinder chamber which have neutralizing effects on the net downward force. a manifold coupled to the cylinder is in fluid communication with the first chamber. a pressure control valve supported by the manifold is in fluid communication with the manifold and the first chamber.abstract: (en)a downforce controller for an agricultural implement having a double-acting hydraulic cylinder. the cylinder is configured to be coupled to an agricultural row unit and an agricultural toolbar for transmitting a net downforce between the agricultural toolbar and the agricultural row unit. a first pressure in the first chamber of the cylinder and a second pressure in the second chamber of the cylinder having counteracting effects on the net downforce. a manifold coupled to the cylinder is in fluid communication with the
