Human and animal powered mechanization systems (Figures 2 and 3) are described in detail in Human and Animal Powered Machinery, EOLSS on-line, 2002. The drudgery, long hours and low pay typically associated with these systems make rural life in the developing countries an unattractive career for young men and women.
Additional and exciting technological developments are taking place in tractor design with emphasis on precision farming, communications and information technologies. These are intended to enhance performance and take account of energy conservation, environmental protection and sustainability considerations. The modern tractor is reviewed in detail in Tractors and Transport (EOLSS on-line, 2002).
