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.
