Wear of agricultural tools by soil particles

The tillage tools in exploitation are subjected to wear, which is caused by motion of working part of tool trough tilled soil mass. In this article, b y tribological approach to observed problem, the tribosystem, wear mechanis m and influential factors of wear process have been defined. The tribosyste m of tillage tool is specific by reason of his structure, what make difficu lt the analyse of the same. The wear mechanism is the example of low-stress abrasion by soil particles mass. The influential factors are classify into a three groups - propertys of abrasives, propertys of wear materials and l oad parameters, and each of factors has been separately analysed.
