Industrial Revolution

Nowadays, highly mechanized agriculture industry, but thousands of years people worked the land by hand or using the power of pets. With what started the history of agricultural technology? Of course, with plow. Plow, as you know, work the soil, turning the top layer of soil, he loosened the soil, removes it from the weeds, making soft. The first people to grow plants worked with his hands or with simple hoes, but it was is only possible in areas with very fertile soil. In places where the soil was not very good yields were low before the invention of the plow that allowed up to the surface more nutritious lower layers. It is assumed that the 6th millennium BC in the area between the first plows had already existed. They were arranged in an elementary way, in a wooden frame (beam) into a sharpened piece of wood (share) perpendicular to the earth. Plough did not change its long construction until the Romans perfected it, they invented the plow, which cast the land to the side and used a special knife to cut the ground before the ploughshare, which facilitated the plowing.

Plow for a long time was made of wood, sometimes with an iron blade. Only in 1730 was put completely iron plow. Since the Industrial Revolution began to make plows from steel. There were 2 or more plows plowshares, but to the appearance of tractors, many of plowshares were not used as a horse can not pull the plow more than one groove, with two only two horses cope, and with a five furrow horse is the limit. Greatly accelerated the emergence of plowing steam engines, gasoline even further ahead of them are not in power. Several steam-engine move could pull a plow and plowed a huge day for the incredible space. Now they use reversible plow, which is not leaves characteristic of the traditional plow ridges.
