An agricultural device may include an elongate housing having first and second ends and defining a cavity between the first and second ends, and a rotating shaft extending longitudinally through the cavity of the elongate housing and coupled to the first and second ends. The agricultural device may include a mechanical gearbox coupled between the rotating shaft and a tractor, and chain segments coupled to the rotating shaft and being longitudinally spaced on the rotating shaft. The mechanical gearbox may be configured to spin the rotating shaft so that the chain segments extend and impact a ground surface.
