“…Так, например, камни, находящиеся в почве и на ее поверхности, способствуют поломкам при работе сельскохозяйственной техники, снижая производительность и надежность ее работы [3,4]. В связи с этим бороны, у которых рабочие органы-диски расположены на одной оси, и дискаторы, рабочие органы-диски которых имеют индивидуальное крепление к стойке, имеющей защиту от перегрузок, позволяющие производить обработку участков с каменистой почвой, являются наиболее производительными почвообрабатывающими средствами [5,6].…”

BACKGROUND: The results of RD works on the laboratory prototype of a small disk harrow aimed for operation at mountainsides and capable to improve labor capacity and yield capacity of highland forage lands by 1520% are presented. AIMS: The developed laboratory prototype of a module of a mountain tractor-drawn small disk harrow for operation at sections of highland and piedmont areas capable to eliminate weed infestation of soil; to increase fertility and yield capacity of forage lands, to ensure stability of grass areas against deflation and erosion. METHODS: The technical examination of the laboratory prototype of the machine was carried out at the highland station of North Caucasian Research Institute of Highland and Piedmont Agriculture in Dargvas village, Republic of North Ossetia-Alania at the altitude of 1540 meters above the sea level and at the slope angle of up to 12. The properties of the testing conditions and the functional properties of unit operation were determined. The technical examination of the scientific documentation of the laboratory prototype of a module of a mountain tractor-drawn small disk harrow for cultivation of soil of highland grass areas was carried out in compliance with the GOST 33687-2015 standard. The subject of the study includes operating tools (the disks), distance between neighboring disks, disk curvature radius, disk diameter as well as the design of operating tools mounting at the frame of a small disk harrow. RESULTS: The laboratory prototype of a small disk harrow for soil cultivation at sections of highland and piedmont areas was developed and produced on the basis of a minitractor. The small disk harrow is represented as a tractor-drawn unit with inline arrangement of 9 spherical disks mounted to individual struts. The design of the mountain small disk harrow is provided with the capability of the unit to switch from the right-to-left mountainside operation mode to the left-to-right mountainside operation mode when turning and with the optional mounting of press wheels. CONCLUSIONS: Practical use of the module of a small disk harrow ensures reduction of generating processes ofmountainside sections, increases yield capacity of forage lands, ensures stability against water erosion and wind erosion as well as increases environmental stability and efficiency of grassland farming.

Abstract. The authors presented the results of scientific developments and a new device for improving and restoring mountain pasture areas by sowing grass seeds on depleted and thinned grass. The absence of small-sized maneuverable units capable of sowing grass seeds on sparse grass in the mountains was revealed. The purpose of the study is to develop and manufacture a laboratory sample of a block module based on a mini-tractor “Fenshow-180”, for surface sowing of grass seeds. The object of the study is agrotechnical techniques and an aggregate for the introduction of grass seeds, providing accelerated restoration of mountain pasture areas, increasing the yield of perennial grasses and soil resistance to water and wind erosion. The objectives of the research included the substantiation of the technology, the assessment of the effect of sowing grass seeds on the change in the qualitative and quantitative composition of the herbage, the possibility of improving plant nutrition and water-air regime, enriching the fodder herbage by sowing valuable types of herbs. Methodology and methods. The tests were carried out in the mountainous zone of the Republic of North Ossetia – Alania, in areas located at an altitude of 1540 meters above sea level. The planting of herbs was carried out on a rarefied section of the northern slope with a steepness of 160 in the area Sugsadtanrag. A technical examination of the unit was carried out according to the agrotechnical requirements and the terms of reference. The surface application of grass seeds was carried out according to the application standards. Results. It was found that the laboratory sample of the unit meets the agrotechnical requirements and technical specifications, the herbage yield increased in various areas from 90–170 %, the botanical composition of the herbage changed, which affected the quality of feed, provided an increase in the nutritional value of meadow grasses from 0.7 to 2.8–3.5 thousand fodder units/ha, with a content of 120–145 g digestible protein per 1 feed unit of dry mass of feed. The conclusion is made about the expediency of using the developed block module in mountain meadows and pastures with a slope of up to 16°. Scientific novelty. For the first time, a technology has been developed and a small-sized seeder based on a mini-tractor for the restoration of mountain pastures has been manufactured.
