The author presented the results of R&D and a new device for restoring and increasing the area of mountain meadows and pastures. It has been found that there is a lack of small, maneuverable equipment for small-contour mountainous slopes covered with hummocks, anthills, and stones, which reduce the yield of forage grasses and contribute to injuries among grazing animals. The purpose of the study is to develop a method and a device that increase the useful area and efficiency of haymaking plots, and reduce degradation processes and increase the yield of forage lands. This method is expressed in the fact that the device performs a step-by-step cutting of hummocks, grinding and leveling the surface of the site. The object of the study is the design parameters of the device, working parts (blades) that prevent it from sliding down the slope, and the quality of the soil cover after the use of the device. The dependencies of the skid of the hill cutter on the slope steepness and the speed of the device when using various anti-skid blades were determined. The tests were carried out in the village of Dargavs, North Ossetia, at the experimental site of the scientific research base of the Scientific Research Institute of the Russian Academy of Sciences. The device was tested in accordance with GOST 33687-2016 "Machines and tools for surface treatment. Test methods", GOST 473117 "Hill cutters". It was found that the slippage of the hill cutter at a slope steepness of up to 150 is relatively small, both when working with a disc and a straight vertical blade and does not interfere with the normal operation of the hill cutter. The quantity and quality of the cut hummocks were determined by counting before and after the passage of the device, the value was 97%.
