Farm machinery, mechanical devices, including tractors and implements, used in farming to save labour. Farm machines include a great variety of devices with a wide range of complexity: from simple hand-held implements used since prehistoric times to the complex harvesters of modern mechanized agriculture.
Until the 1950s mechanization played only a minor role. The emphasis on biological technology was supported by conscious government choice: in the late nineteenth century Japan imported machinery from the United States, but did not find it useful. It then hired biologists from Germany to assist in developing its biological research program, which was successful. The United States, however, emphasized mechanical technology even before 1880. Although publicly funded biological research was initiated in the 1870s, it did not produce big increases in yields until about 1930, well after the major land frontiers had been closed and mechanization was far advanced.
