It is possible to refer less uniform distribution of seeds on nourishing area to shortcomings of two-disk plough share. For the elimination of this shortcoming two-disk plough share for narrow-rowed crops where seeds keep within 2 rows in one groove with distance between them 7.5 cm are produced. General angle of disks attack makes 23 with the angle of heel to the surface of the soil 20°. Such design feature the de-mands more thorough preparing of the soil, besides, two-disk plough share quickly lose working capacity during the work in the conditions of increased humidi-ty of the soil owing to sticking of working surfaces of disks by damp soil that does not allow to carry out sowing works to the best agrotechnical terms, espe-cially in the conditions of rainy spring. The research objective was to improve the technology of crops of seeds of grain crops in the conditions of increased humidity and technical means for the implementation of this type of work. For the solution of the objective a new design of making furrow worker of body for a seeder adapted for the work in the conditions of in-creased humidity of the soil is offered. New furrow making working body is plough share (the patent of Russian Federation No. 2511237). It allows to achieve the goal thanks to two furrow making disks installed parallel to the direction of the movement of the unit and are executed as disk knives with cutting edges on both sides of which bolts furrow making slips from polymeric material possessing hydrophobic properties fasten that interferes with sticking of damp soil to working surfaces of furrow making disks. The results of theoretical researches of work of a furrow making disk show that received analytical depend-ences allow optimizing constructed parameters of the disk for the formation of a profile and a bottom of a furrow. The dependences for the definition of the re-actions of the soil operating on furrow making disk during the work, the density of the bottom of the fur-row formed by a plough share, the design data of seeding section and the uniformity of depth of the course important for power assessment of new clos-ing-up worker of body have been established.
