The Mechanisation of Farming
The mechanization of agriculture is often considered to have begun with the 18th-century inventions ofjethro Tull's mechanical seed drill of 1701 and Andrew
Meikle's threshing machine, patented in 1788, but these inventions built on far older technology. Carvings excavated at the Babylonian city of Ur show that wheeled carts were in use as early as 4000 BC. They are also known to have been used in India shortly afterwards.
Knowledge of this invention spread so that by 2000 BC the use of wheels had reached Persia, and then Europe by about 1400 BC. Initially the wheels were fixed to an axle and the whole assembly rotated, but this was later refined so that just the wheels rotated. Many kinds of animals were used to pull carts, including oxen, water buffalo, donkeys, horses, camels, elephants and even slaves. Tracks, and then roads, suitable for use by primitive vehicles were built. The next development of equivalent importance was the mechanical means of propulsion.
