A new plow with a heavy iron plowshare enabled peasants to plow fields in about half the time it took before, made it possible to till much deeper into the soil, and made breaking the soils of Northern Europe and Britain possible. This went along with the development of a collar allowing farmers to hook these plows to horses, which are not as powerful as the oxen that were usually used for plowing.
