Summary: A study was conducted aimed at studying the problems of the reliability of coulter discs and proposing ways, methods of restoring and optimizing the design of coulters of grain seed drills to maximize their reliability and durability. Grain planters in agriculture play a key role in the process of growing crops. However, one of the most important components of these units are coulter discs, which are often exposed to aggressive conditions and heavy physical loads. Ensuring the reliability of coulter discs of grain seeders is a key aspect in agricultural production, since the efficiency of the technological process of sowing directly affects the yield and quality of agricultural crops. A thorough analysis of the geometry and materials of the disks was carried out to identify weak points and potential sources of activation, as well as to determine the main factors that lead to their wear and destruction. The values and distribution of the residual stresses in the material of the new disk and the restored one by welding three segments made of steel with surmite surfacing and vibration hardening were determined. The values of the degree of strengthening of the material of the cutting edge of restored coulter discs were found. Optimal modes of vibration strengthening are established: frequencies and amplitudes of oscillations of the processing tool, time. The research makes it possible to develop an optimized design of opener discs, which will ensure their high reliability and service life during various operating conditions. The results of the research will be used to improve the technical characteristics and production technologies of coulter discs, which will help to increase productivity, reduce the costs of repairing seed drills and ensure efficient sowing.
