A plow is a farm implement for tilling the land. It is composed of a heavy blade at the end of a beam. It is usually tied to a group of livestock or motor vehicles to pull it. It can also be driven by manpower. It is used to break up soil and plow grooves to prepare for sowing. In order to speed up the tillage rate, more plow teeth are generally added to the plow to form a multi-tooth plow.
