Wearing ability of soils and its effect on the durability of the working bodies of tillage machines

Wearing the soil´s capacity is the main factor affecting the durability of parts and compo-nents of tillage machines and the life of the machinery and tools in general. The article shows the influence of the different soil types on the degree of wear of the working bodies and it was found that the wear rate depends on the texture, moisture content, density and uniformity of the soil, the speed and shape of working bodies, the properties of the materials of which they are made. An analysis of the nature of plowshares wear, ripping tines, disc of harrows, seeders openers and knives of cutters was done.
