The article considers a certain consistency in the configuration of various grain seeder manufacturers with chisel-shaped (anchor) coulters with individual (rubberized, pneumatic, metal wedged) rollers in the furrow, which provides the possibility of more favorable conditions for seeds relative to their location in a moist layer with compaction of the soil covering them. The purpose of the research is to select the most optimal seeders with chisel-shaped working bodies, which allow efficient sowing with all known technologies, but especially today intensively implemented “No-Till”, “Mini-Till”, in moist deeper soil layers 10–12 cm, observing the optimal depth of seeding – 4–5 cm. The studies confirm an increase in the quality of sowing, especially with insufficient soil moisture and early aligned shoots using “No-Till”, “Mini-Till” technologies, which is important for most regions of the Russian Federation with “risky” agriculture and due to the predicted global warming. The research results are of particular importance when sowing winter crops, with the necessary development-tillering for their reliable overwintering and the formation of high yields
