ARD: An ancient light plow with a simple blade that was used to scratch the surface of the soil rather than turn furrows. It was drawn by animals or people and grooved the ground, but it had no mold board or colter and therefore did not turn over the soil. With this type of plow cross-plowing was usually necessary, with a second plowing at right angles to the first.
