Justification of ways to increase the durability of tillage working bodies

Based on an analysis of the features of operation of tillage working bodies proposed methods to increase their durability, combining intermittent overlaying welding surfaces by wear–resistant materials and influence deep cold. Justified stand options for cryogenic influence on details of tillage machinery. The results of the experiment for the realization of the offered methods of durability for example loosening claws of the tiller are give
