In modern agriculture, preference is given to agricultural machinery that enables the technological process to be carried out efficiently and in the shortest possible time. The article presents the design of a combined coulter, which enables high-quality distribution of seeds both in the length of the row and in depth at increased speeds. Compared to analogous devices, due to the original design of the ripper (seed guide), there is no mixing of soil and seed during work, which has a positive effect on improving the quality of work. The purpose of the theoretical study was to improve the quality of crop sowing by developing and using a combined coulter with a ripper (seed guide). Based on the results of the research, theoretical dependencies were determined, which made it possible to determine the index of the kinematic mode of seed flight, the optimal speed of the machine-tractor unit, as well as the angle of inclination of the curved part of the ripper. In the process of the research, the equa-tions of motion of a seed and a soil element during coulter operation were established. As a result of theoretical calculations, it can be noted that the index of the kinematic mode at a soil moisture content of 17-19% is 0.20...0.23 and at the same time the speed of the machine corresponds to 3-3.5 m/s.
Keywords: coulter, seeder, theoretical research, soil, sowing, seeds.
