Agricultural mechanization has involved the partial or full replacement of human energy and animal-powered equipment (e.g. plows, seeders and harvesters) by engine-driven equipment. Most of this is tractor driven and to a lesser extent self-propelled equipment (including harvesters, sprayers, fertilizer applicators, planters and seeders). Agricultural mechanization has been pioneered in North America and Europe and more recently in Japan, and is now spreading rapidly throughout the world. Notwithstanding such progress, a significant element of human and animal powered mechanization remains, particularly in the poorer regions of the world.
While much remains to be done on small farms in the poorest regions, sufficient progress has been made to accelerate food production in line with population growth (contrary to the Malthusian prediction). In this theme, farm machinery is considered with primary emphasis on engine and motor driven machines and implements and a lesser emphasis on human or animal powered equipment.
