<P> The entire history of agriculture contains many examples of the use of tools, such as the hoe and the plough . But the ongoing integration of machines since the Industrial Revolution has allowed farming to become much less labour - intensive . </P> <P> Current mechanised agriculture includes the use of tractors, trucks, combine harvesters, countless types of farm implements, aeroplanes and helicopters (for aerial application), and other vehicles . Precision agriculture even uses computers in conjunction with satellite imagery and satellite navigation (GPS guidance) to increase yields . </P> <P> Mechanisation was one of the large factors responsible for urbanisation and industrial economies . Besides improving production efficiency, mechanisation encourages large scale production and sometimes can improve the quality of farm produce . On the other hand, it can displace unskilled farm labour and can cause environmental degradation (such as pollution, deforestation, and soil erosion), especially if it is applied shortsightedly rather than holistically . </P> <P> Jethro Tull's seed drill (ca . 1701) was a mechanical seed spacing and depth placing device that increased crop yields and saved seed . It was an important factor in the British Agricultural Revolution . </P>
