An agricultural row unit includes an attachment frame adapted to be rigidly connected to a towing frame. A linkage assembly is pivotably coupled to the attachment frame to permit vertical pivoting movement of the linkage assembly relative to the attachment frame. A hydraulic cylinder is coupled to the linkage assembly for urging the linkage assembly downwardly toward the soil. A hose connection manifold is mounted adjacent to the hydraulic cylinder for circulating hydraulic fluid between a hydraulic source and the hydraulic cylinder. The hose connection manifold has a plurality of ports including an inlet port, an outlet port, and a valve port, the inlet port being adapted to receive an inlet hose, the outlet port being adapted to receive an outlet hose, and the valve port being adapted to receive an end of a hydraulic control valve.

The agricultural row unit of claim 1, wherein the hydraulic control valve is a hydraulic cartridge valve attached to a control module. 3. The agricultural row unit of claim 2, wherein the control module includes one or more of a pressure transducer, embedded electronics, and an electronic connector. 4. The agricultural row unit of claim 1, wherein hydraulic control valve is removably connected to the hose connection manifold via the valve port. 5. The agricultural row unit of claim 1, wherein at least one of the plurality of ports is plugged. 6. The agricultural row unit of claim 1, further comprising an accumulator enclosed at least in part within a protective cover and mounted to the hydraulic cylinder, the protective cover having a central axis parallel to a central axis of the valve port. 7. The agricultural row unit of claim 6, wherein the central axis of the valve port is perpendicular to a central axis of the hydraulic cylinder. 8. The agricultural row unit of claim 1, wherein the inlet port receives a first end of the inlet hose, a second end of the inlet hose being connected to the hydraulic source. 9. The agricultural row unit of claim 1, wherein the inlet port receives a first end of the inlet hose, a second end of the inlet hose being connected to the hydraulic source, the outlet port receiving a first end of the outlet hose, a second end of the outlet hose being connected to an adjacent row unit. 10. An agricultural system, comprising: a hydraulic source for supplying pressurized hydraulic fluid;a towing frame attachable to a towing vehicle;a first row unit attached to the towing frame and including a a first hydraulic cylinder for urging the first row unit downwardly toward the soil, anda first hose connection manifold mounted adjacent the first hydraulic cylinder for circulating hydraulic fluid between the hydraulic source and the first hydraulic cylinder, the first hose connection manifold being a valve-less manifold; anda second row unit attached to the towing frame and including a a second hydraulic cylinder for urging the second row unit downwardly toward the soil, anda second hose connection manifold mounted adjacent the second hydraulic cylinder for circulating hydraulic fluid between the hydraulic source and the second hydraulic cylinder, the second hose connection manifold including a hydraulic control valve. 11. The agricultural system of claim 10, wherein at least one of the first hose connection manifold and the second hose connection manifold receives hydraulic fluid directly from the hydraulic source. 12. The agricultural system of claim 10, wherein at least one of the first hose connection manifold and the second hose connection manifold received hydraulic fluid indirectly from the hydraulic source, via a respective adjacent row unit. 13. The agricultural system of claim 10, wherein each of the first hose connection manifold and the second hose connection manifold has a plurality of ports including one or more of an inlet port, an outlet port, and a valve port. 14. The agricultural system of claim 13, wherein the hydraulic control valve has an end received within the valve port. 15. The agricultural system of claim 13, wherein the hydraulic control valve is removably received within the valve port. 16. The agricultural system of claim 13, wherein at least one of the plurality of ports is plugged. 17. The agricultural system of claim 10, wherein the hydraulic control valve is a hydraulic cartridge valve attached to a control module. 18. The agricultural system of claim 17, wherein the control module includes one or more of a pressure transducer, embedded electronics, and an electronic connector.
