When sowing seeds of grain crops, it is important to ensure their uniform distribution over the area and depth, laying on a compacted bed. When the seeds are evenly distributed, they do not thicken during germination, which causes a decrease in yield. The purpose of the work is a comparative analysis of the statistical characteristics of the seed distribution over the area of the experimental and serial coulter. The design of the proposed coulter contains a pitched plate that provides a horizontal furrow surface. This is a prerequisite for increasing the uniformity of seed sealing. The results of field studies of an experimental coulter for sowing grain seeds and applying fertilizers below the seed layer are presented. A comparative analysis of the uniformity of the distribution of oat seeds over the area of sowing by an experimental coulter and a serial seed drill SZP-3.6A-0.2B. Studies have shown that the experimental coulter distributes seeds more evenly over the sowing width. This has a positive effect on their further germination. Statistical indicators of coulters are compared.
