“…A number of scientists consider the need to equip agricultural machines with various safety devices as one of the ways to reduce injuries in agriculture [4]. In relation to tilthers, they are described in [5][6][7][8][9]. However, many scientists prefer to improve the design of the tractor itself, designed to operate in difficult conditions [10][11][12].…”

The article is devoted to the search for a mathematical model convenient for practical calculations to determine the critical value of the angle of gradient for the tractor-mounted heavy tilther. It shows the existing mathematical model, which is then refined based on the stiffness of the elastic tractor wheels and their vertical reactions offset. Three methods of solving the resulting equations are analyzed, upon which the optimal one is chosen. As a result, a simple and convenient in practice mathematical model to determine the critical value of the angle of gradient for the tractor-mounted implement is obtained. The analysis of the calculation results showed that depending on the operating conditions and the weight of the tractor counterweight, the differences between the results calculated using the traditional and refined models can reach more than 4 degrees, which is very important to ensure the hill climbing safety.

Abstract. The authors present the technology and descriptions of aggregates for hay harvesting on mountain slopes. The aim of the study is to reduce the loss of green mass when harvesting hay with the use of mountain modification aggregates, to improve the safety of hay with the use of a preservative (table salt). The object of the study is a complex of hay harvesters, aggregated with low-clearance tractors, designed to work on sloping areas with a slope of up to 16°. The tasks of the research included: to select a set of hay harvesters, to study and use their technical capabilities, which allow optimizing the harvesting time, ensuring the lowest losses of the harvested feed, increasing its quality and safety for the winter-stable period of keeping animals. The novelty of the technical solution is that the selected haymaking machines allow you to reduce the time of haymaking operations in mountainous areas and reduce the cost of manual labor. Tests of this technology were carried out in the mountain zone of the RSO – Alania (Dargavs basin, the stronghold of the SKNIIGPSH) at an altitude of 1540 m above sea level in the south-eastern exposure with a slope steepness of up to 150. Results. It was found that the content of pressed hay increased-feed units by 32.1 %; dry matter by 29.6 %; crude protein by 17.3 %; fat by 7.4 %; fiber by 14.2 %; sugar by 17.6 %; metabolic energy by 8.0 %. The developed technology allows more than 1.2 times to reduce mechanical losses, provides an increase in productivity compared to manual harvesting in 4–5 times, reducing the time cleaning 3 times at the same time increase the nutritive value of forage mass, increases palatability harvested forage 18.5 %, which positively affects the physiological condition of the animals during the winter housing period, increasing milk yield is 11.7 %.

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.
