Mechanized agriculture is the process of using agricultural machinery to massively increase farm output. In modern times, powered machinery has replaced many jobs formerly carried out by men or animals such as oxen and horses.
The history of agriculture contains many examples of tool use, but only in recent time has the high rate of machine use been at such a level.
The first pervasive mechanization of agriculture came with the introduction of the plough, usually powered by animals. It was invented in ancient Mesopotamia.
Current mechanized agriculture includes the use of airplanes, helicopters, trucks and tractors, among other vehicles. Modern farms even sometimes use computers in conjunction with satellite imagery and GPS guidance to increase yields.
