A self-cleaning plow was made out of a broken steel blade which he carefully polished. It was a work of the inventor John Deere. He has carefully thought about the material for a moldboard, about its shape, the curve line. Deere has cautiously analyzed the trouble and made a conclusion that people needed a plow that would be cleaned by itself, without any assistance. Working with cast-iron plows farmers had to stop their work very often to clean the sticky soil off of their plows. The farmers’ work in the field was hard as the Midwestern dark-brown soil, one of the richest in the world, was very difficult to plow for the reason of high viscosity.

The history of the company started in 1837 in Grand Detour, Illinois where John Deere, the founder of the company, opened a blacksmith shop to repair and manufacture horseshoes, pitchforks, shovels and other small things needed by farmers. But Deere & Company has factories, offices and other facilities in over 30 countries so that Deere’s specialists could see and act in response to their clients’ demands in any part of the world. The company's headquarters is located in Moline, Illinois, USA. Over the years it has changed to this or that extent but it was always with a leaping deer which graceful figure symbolized permanent creation and revival. John Deere’s logo was registered for the first time in 1876 and became one of the most recognizable logos in the world.

In addition diesel engines, transmissions for heavy machinery, gardening equipment, snow machines are also released by the company. Besides the company produces construction machinery, such as excavators, loaders, tracked loaders, graders, bulldozers and others, as well as a range of forestry equipment covering harvesters, forwarders and skidders, which in 2000 was supplemented by timberjacks. John Deere is a brand name of an American corporation Deere & Company, which specializes in manufacturing of agricultural machinery including tractors, combine harvesters, cotton harvesters, sprayers, silage technique, planters, seeders etc.
