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 given

The results of research on the influence of wear-resistant hardening surfacing on bionically justified parameters on the efficiency, durability and traction resistance of cultivator hoes and hoe coulters are presented. The economic efficiency of the proposed method of strengthening the hoe working bodies is determined.
