Agricultural system for field preparation

An agricultural system comprising:

• a tow bar for attachment to a towing vehicle in a trailing position relative to a direction of movement along a field;
• a plurality of row-cleaning devices attached in parallel strip positions along the tow bar, the plurality of row-cleaning devices including a first row-cleaning device and a second row-cleaning device,
• the first row-cleaning device being attached in a first strip position and including
• a first rigid frame for attachment to the tow bar,
• a first leading coulter,
• one or more first furrow-opener disks in a trailing position relative to the first leading coulter, and
• a first pivotable row-cleaning linkage attached to the first rigid frame, the first leading coulter and the first furrow-opener disks being coupled to the first rigid frame via the first pivotable row-cleaning linkage;
• the second row-cleaning device being attached in a second strip position, the second strip position being adjacent and parallel to the first strip position, the second row-cleaning device including
• a second rigid frame for attachment to the tow bar,
• a second leading coulter,
• one or more second furrow-opener disks in a trailing position relative to the second leading coulter, and
• a second pivotable row-cleaning linkage attached to the second rigid frame, the second leading coulter and the second furrow-opener disks being coupled to the second rigid frame via the second pivotable row-cleaning linkage;
• and
• a roller device attached between the first row-cleaning device and the second row-cleaning device, the roller device including
• a first pivotable roller linkage attached at a first end of the roller device and being independently movable from the first rigid frame,
• a second pivotable roller linkage attached at a second end of the roller device and being independently movable from the second rigid frame, and
• at least one roller bearing mounted along a rotational axis of the roller device.
