Soil tillage machinery with the main function of turning soil and loosening and breaking soil. The main types are spar plow, disc plow, rotary plow and so on. Egypt, China, Persia and other ancient agricultural countries had primitive wooden plows pulled by oxen three or four thousand years ago. The European spar plow was founded in the 8th century, and in 1847, the disc plow was patented in the U.S. In 1896, the Hungarians created the rotary plow. The spar plow is the most widely used plowing machine in the world. The disc plow has a better ability to cut grass roots, but the mulching performance is not as good as the spar plow. The soil tilled with the spar and disc plow is generally not as fine and flat as required for sowing, and must be harrowed and suppressed for subsequent operations. In addition, plowing with spar and disc plow requires a lot of traction, and the tractor generated by the large traction is limited by the tire attachment performance, its power is not fully utilized. since the late 19th century, many countries and regions are exploring new tools for plowing, creating a variety of drive-type soil tillage machinery, such as rotary tiller, rotary hoe, etc.. Their outstanding advantage is that they can obtain a very loose and fine seed bed at one time, but the productivity is lower, energy consumption is higher, and the function of turning and burying stubble, weeds and fertilizer is not as good as that of the spar plow.
