The purpose of the study is to increase the uniformity of seed placement at the sowing depth by using a coulter disk with epicycloidal grooves along the contour. The studies were carried out on the fields of LLC "Russkoe Pole" in Serdobsky district of Penza region in 2022-2023 using the C-6PM3 pneumatic seeder with the developed working bodies, which are coulters on the disks of which there are grooves on the contour in the form of an epicycloid, according to the methods of STO AIST 5.6-2018. The quality of the sowing carried out was assessed in accordance with GOST 31345-2017. Laboratory tests in the field using the C-6PM3 pneumatic seeder equipped with coulters with epicycloidal grooves along the contour have proven the reliability of the tests carried out in laboratory conditions, where the difference between the data was no more than 5%. The studies carried out made it possible to specify the structural dimensions of the coulter, on the disk of which grooves along the contour are in the form of an epicycloid. Based on the research results, the main design parameters of the experimental pneumatic seeder C-6PM3 equipped with coulters with epicycloidal grooves along the contour, which were determined in the laboratory studies, were specified.
Keywords: grain seeder, laboratory and field studies, single-disk coulter, sowing depth, seed distribution, soil.
