Abstract: One of the main working bodies of grain seeders is the coulter, the work of which determines the uniform distribution of seeds along the length of the furrow and the depth of their seeding. Of the wide variety of used coulters, the most widespread are double-disc coulters, since they have less traction resistance and better quality indicators of their work. However, as shown by scientific research of foreign and domestic scientists, when the double-disc coulters are working, the quality indicators of their work are not met, as a result of which the yield of the cultivated crop decreases. To eliminate the noted drawbacks during the operation of double-disc coulters in the Penza State Agrarian University, innovative double-disc coulters for a grain seeder have been developed. During the operation of these coulters, in comparison with the serial ones, thanks to the installation of a seed guide, a soil ripper and a seed speed damper on the coulters, the seeds are evenly distributed along the length of the furrow and the depth of their planting.
