Combined tool for improving arid pastures

Abstract

The purpose of the study is to substantiate the advantages of the combined tool developed by the authors for improving pastures. The device of a tool for improving pastures is given. The results of comparative tests of existing guns and a mock-up sample of a combined gun are presented. During field experiments, fuel consumption, unit performance, soil crumbling, hardness, humidity, and soil density were determined. The calculation of the technical and economic indicators of the tool was carried out. According to the results of tests and calculations, it was found that the combined tool surpasses the existing tools used to improve pastures in terms of the main technical and economic indicators. At the same time, the developed tool allows to increase labor productivity by 6.1 times and reduce fuel consumption by 84.7%. As a result, annual labor savings amount to 823.1 people • h, operating costs will decrease by 82.5%.
