In the territory of the Republic of Crimea, the production of growing cereal crops in arid conditions is becom-
ing topical. The most effective method is the introduction of a system of saving farming. Existing analogues of seeders
with disc coulters in conditions of heavy and loamy soils of the arid region of the Republic of Crimea have limited
opportunities. A scheme of sowing with rolling out at the level of seed occurrence and a construction of a vomer sec-
tion with a roller pressing in the seeds is proposed. This scheme includes: cropping of soil; Seedbed formation; Distri-
bution and indentation of seeds into the soil; Transportation and separation of the undercut loose soil layer; Upsetting
and leveling of the soil covering the seed. The structure of the proposed vomer section includes a stand on which a
seed conduit, a diffuser and a cultivator leg with two flat-cutting knives and a chisel are fixed. A rolling device with
a cutter in the form of an ellipsoid of rotation is hinged to the stand. Behind the packing roller to the frame there are
attached lamellar tines, made in the form of segments of a logarithmic spiral. At justifying the design parameters and
operating modes, methods of theoretical and agricultural mechanics, mechanics of continuum, elasticity theory, inte-
gral and differential calculus were applied. Taking into account the need to ensure an even distribution of the sealing
action of the paw on the soil, an analytical expression describing the law of distribution of the contact pressure of the
cutting edge of the paw on the soil was obtained, which allowed to justify the shape of the cutting edge of the blade of
the paw of the vomer section. The shape of the cutting blade is determined taking into account the physico-mechanical
properties of the soil: the deformation index, the shear modulus and the friction coefficient of the blade on the soil. The
shape of the compacting roller is determined, which ensures the uniformity of indenting seeds into the soil compacted
by the blade. The roller must have the form of a truncated ellipsoid of revolution. Covering the dented seeds with a
roller is carried out by the guide trays. Overtake is carried out with the final precoating and leveling of the soil surface.
Key words: sowing, working organ, soil moisture, traction resistance, opener, cutting edge, packing,
deformation index, soil bed
