“…However, not all used seeders fully meet the agro technical requirements of sowing. The main task of the grain seeder is the uniform distribution of seeds over the coulters [3], the uniformity of the sowing depth [4][5][6], the creation of an optimal density of the soil layer between the seeds, the control of reliable seeding of seeds and its automation [7][8][9].…”

The assessment of modern grain seeders was carried out according to five indicators: price of the seeder, metal consumption and energy intensity of sowing, specific productivity and technical level of the seeder. Weight coefficients were introduced for each indicator. A method for making an objective decision for choosing the best seeder option from alternative options based on the Harrington function is substantiated. The desirability function has been modernized into a graphical form using rating scales. Any intermediate value of the estimated indicator was projected onto a segment of a straight line connecting the points of intersection of the lines of the minimum and maximum values of the estimated indicators and the extreme lines of the same indicators, projected from the Harrington desirability function to a dimensionless scale. Dependences of the indicators of the desirability function for all evaluated indicators are determined. A generalized indicator of a comprehensive assessment is formulated for making a final decision. As a result, it was found that the ALFA-6 seeder has the best performance. Seeders SZT-3.6 and SZP-3 received the worst rating. Their overall score is 42.9% lower than the ALFA-6 planter. The developed assessment methodology made it possible to outline ways for further improvement.

“…Taking into account the specifics of this technology, direct seeding machines operate in the conditions of increased soil resistance and a substantial amount of postharvest residues. These factors can significantly deteriorate the quality of the seed distribution in depth, which is mainly preconditioned by the instability of the coulter motion [1][2][3].…”

The paper presents the results of theoretical and experimental studies of the operating process of the seeder section for the no-till sowing machine. Based on the theoretical studies, the authors derived the dependences allowing one to obtain the motion trajectories of the seeder section elements with a parallelogram mechanism when following (gauging) the microrelief contour of the soil surface, taking into account its design parameters. The obtained theoretical trajectories were used as a basis for identifying rational parameters of the gauge wheel of the section. The results of the theoretical studies were confirmed experimentally by the laboratory experiments on a tillage bin, using the developed prototype of the seeder section when following artificial roughnesses. A comparison of the results of the theoretical and experimental studies demonstrated a sufficient degree of their convergence. The authors also established a regularity of the change in the uniformity of the coulter motion of the seeder section relative to the microrelief of the soil surface, depending on its position relative to the gauge wheel.

“…Tools are important elements of seeding machines used in the no-till technology [1][2][3][4][5]. These are generally combined sowing sections simultaneously performing several heterogeneous operations: cutting the upper compacted soil layer, furrowing, laying the seed into the soil, and seeding down [4,5].…”

The paper presents the results of studying the tractive resistance of the combined sowing section for no-till technology-based seeding. The sowing section consists of a slotting disk, an anchor colter, and a press wheel. To ensure the stability of the colter motion, the section has a parallelogram suspension and a balancing wheel with an adjustable vertical force acting on it, depending on the soil resistivity and the tilling depth. The sowing section ensures that the seeds are sown at a given depth in a moistened soil layer according to the agrotechnical requirements. Based on the theoretical studies, an analytical dependence was obtained, which allows for determining the tractive resistance of individual tools and the sowing section, depending on the design and operating parameters. The paper presents the results of the experimental studies on the dynamometer testing of the sowing section in laboratory conditions. To this end, an analog-digital measuring and computing complex and a software suite were used for the experimental data's post-experimental processing. Experimental dependences of the tractive resistance of individual tools and the sowing section, in general, were obtained, confirming the theoretical studies' correctness. The nominal tractive force of tractors was approximately determined, and the results of laboratory-field and field experiments with the sowing complex were presented.
