The working parts of soil cultivation and sowing machines operate under conditions of intense abrasive wear. As wear on the working parts increases, the relative unevenness of their travel depth increases, leading to higher traction resistance and, consequently, higher specific fuel consumption. It has been established that the intensity of changes in the mass, wear volume, and geometric characteristics of working parts is determined by the combined influence of the treated area and the soil’s mechanical and physical properties, leading to differences in the service life before reaching the critical wear threshold. Studies based on scientific articles have shown that modern strengthening methods can significantly increase the service life of agricultural machinery working parts by 1.5 to 5 times. There are various methods for restoring and strengthening working parts, increasing their wear resistance and durability. New materials are used to increase the service life of working parts; they are hardened during manufacture and, during operation, restored and made more wear-resistant. This research aims to increase the wear resistance of the coulter anchor for seed and fertilizer application by welding a T-620 electrode to its working surface. The following steps were taken to achieve this goal: theoretical research, calculations, the verification of the results using computer modeling (Rocky DEM 2024 R1.1 software package) to predict the abrasive wear of hard surfaces, as well as laboratory and field tests to confirm the results of the theoretical and experimental scientific research.
