“…In order to verification of calculations and results, the average numerical values of the variables included in the obtained formulas have been taken based on known theoretical data (Panov and Vetokhin, 2008;Sineokov and Panov, 1977), they are: α = 30°; φ = 30°; φ1 = 40°; θ = 45°; β = 75°; 2b = 0.03 m; h = 0.1 m; ϑ = 2.77 m/s; σur = 15 kg/cm; ρ = 10 3 kg/cm. Accordingly, they obtain: A = 0.087; B1 = 0.22; B2 = 592; Rz = 748.93 N; Q = 28.19 N. The traction force of the working body is equal to P = 720.73 N. The obtained result is close to the expected one.…”

Due to the depletion of pastures, fodder provisioning is becoming an acute problem, therefore improving pastures by sowing seeds undercover crops and in turf is essential. The main purpose of the work is to reduce the traction force of the sod seeder by developing an effective working body. As a result, a new technology for improving forage and pasture lands and the design of a working body of sod seeder for site-specific seeding of crops undercover crops are proposed. The new technology provides simultaneous sowing of grass seed and fertilizer at two levels of soil horizon without excluding the forage area from the exploitation: grass seed to a depth of 40 mm and fertilizer to a depth of 120 mm. The seed sowing and fertilizer application depths are adjustable, and the sowing width reaches 40 mm. The traction force was determined by the dynamometric method during laboratory and field experiments. Theoretical studies have determined the dependence of the traction force on the average parameters of the cultivated soil layer and its physical and mechanical properties, as well as the parameters of the working body. According to the results of experimental and field studies, the traction force range of the sod seeder was within 8.28-8.63 kN.

“…Регион обладает обширными площадями деградированных кормовых угодий и залежных земель, которые могут быть введены в производственный оборот достаточно быстро и недорого, но на практике отсутствуют эффективные ресурсосберегающие технологии их рекультивации, удовлетворяющие экологическим требованиям [4,5]. Наиболее перспективной из существующих является агротехника, базирующаяся на прямом полосном посеве семян трав в дернину с механическим разрушением полосы дернины шириной не менее, чем необходимо для успешного прорастания семян и развития всходов без использования гербицидов для подавления ценотических связей и снижения конкуренции за факторы среды в ценозе [6,7,8,9], для осуществления которой разработано семейство дернинных сеялок с фрезерными бороздовскрывателями [10,11,12,13]. Метод разработан для применения на лугах и пастбищах, поддерживаемых в продуктивном состоянии, поэтому для эффективного использования в условиях деградированных кормовых угодий и залежных земель его агротехника и конструкция дернинных сеялок должны быть адаптированы к ним.…”

For the effective use of sod seeders SDK in conditions of degraded forage lands, it is necessary to modernize the design of their coulter group to work in conditions of high soil moisture and increased content of plant residues in it. A method of strip sowing is proposed, which is based on the removal of the sowing working elements from under the casing of a milling furrow opener, and a design and technological scheme of the coulter group with a shoe opener mounted on a suspension mechanism in the form of torsion springs. The coulter group includes a mounting bracket on a seeder, a suspension mechanism, shoe openers, rollers, mechanisms for adjusting the position of coulters in the vertical and horizontal planes and the forces of deepening coulters and the pressure of rollers on the soil. Compared to the coulter group of SDK seeders, its weight (19.6 kg) is reduced by 3.8 kg while the total length of the seeder increases by 0.12 m. To assess the efficiency of the modernized coulter group of the sod seeder, experimental studies were carried out in the field, during which the quality indicators of seed placement were determined when using a serial coulter group of SDK seeders and a prototype coulter group. Comparative studies of coulter groups of a sod seeder showed that when sowing Eastern galega, the depth of seed placement complies with agrotechnical requirements and is: for the coulter group of SDK seeder – 19.4...22.4 mm, for the prototype - 18.6...19.5 mm, and for the prototype the value of the standard deviation is almost two times lower. The uniformity of the distribution of seeds over the width of the strip for the coulter group of the SDK seeder is 20.2...26.1 mm, for the prototype – 8.4...10.1 mm.
