An agricultural system includes a tow bar for attachment to a towing vehicle in a trailing position relative to a direction of movement along a field. The system includes a plurality of row-cleaning devices attached in parallel strip positions along the tow bar. Each row-cleaning device has a rigid frame, a leading coulter, one or more furrow-opener disks, and a pivotable row-cleaning linkage. The disks have a leading edge adjacent to a trailing edge of the coulter. The row-cleaning linkage is attached to the rigid frame, with the coulter and disks being coupled to the rigid frame via the row-cleaning linkage. The system further includes a roller device between two adjacent parallel strip positions and attached at each end to a respective rigid frame via a respective pivotable roller linkage. The roller linkage is independently movable relative to the row-cleaning linkage.
