The aim of the study is to study and analyze the process of penetration (deepening) of the frontal plow. Dependencies are obtained for determining the length of the deepening of the serial and frontal plows into the soil. The dynamics of the process of deepening of the frontal plow is analyzed depending on its dynamic characteristics. A differential equation is obtained that characterizes the process of deepening the frontal plow. Theoretical and experimental studies have established that the depth of the frontal plow is significantly affected by the weight of the plow, traction resistance and the relative position of its working bodies. The length of the path of penetration of the frontal plow does not depend on the width of the plow and is 2.0-2.5 m, which is 3-3.5 times less than the path length of a serial plow of equal width.

The aim of the study is to study and analyze the physical, mechanical and technological properties of the soil of the cotton growing zone. The results of determining the relief of cotton fields, physical, mechanical and technological properties of takyr soils and gray soils, and the most common in areas of cotton cultivation are presented. It was found that before plowing, cotton fields have a pronounced uneven relief, characterized by the presence of ridges and irrigation furrows. The average height of the ridges in fields with row spacing of 90 and 60 cm is 17.1 and 12.8 cm, respectively. The physical-mechanical and technological properties of the soil of the arable and sub-arable layer of a cotton field along the track of wheels differ significantly from the soil between rows without a track of wheels and a ridge: the density of the soil along the track of the wheels of light gray soils reaches 1.78 g/cm3, and of takyr soils - 1.51 g/cm3, which is respectively more than the density of the ridge soil by 0.24 and 0.16 g/cm3; the resistance of light gray soils to shear is 1.4 and 1.2 times greater than to rupture and torsion, and takyr soils - 1.33 and 1.15 times, respectively; density, hardness and resistance of the soil to various deformations has a maximum value in layers of 15-25 cm along the track of the tractor wheels.

The purpose of the study was to substantiate the technology and parameters of the “paraplau” type soil dredger for a two-tier plow. The basic principles and methods of classical mechanics, mathematical analysis and statistics were used in this study. Sub-tillage loosening of the most compacted layers of the soil of the fields from under the cotton must be carried out in a strip way along the line of the middle of the irrigation furrows between the rows. It is established that for the implementation of strip loosening of the subarable soil layers of fields from under cotton, the width of the two-tier plow should be a multiple of the width of the row spacing. At the same time, for loosening the compacted subsurface layers of the middle of the row spacing of cotton with one working body, the soil dredgers are installed behind each even lower body in the plane of the field edges of the odd bodies. In the case of subtillage loosening of the middle of the row spacing by two soil dredgers with an inclined stand, one soil dredger is installed behind each lower body. An analytical relationship is obtained to justify the relative position of the plow bodies and the soil dredgers, as well as their parameters. Experimental studies have established that the resistivity of a two-tier plow decreases (in comparison with continuous loosening) when the most compacted layers of the middle of the row are loosened with a pointed paw by 17.56%, two soil dredgers with inclined posts by 24.04%, and one soil dredger with an inclined post by 23.24%.

The paper studies the direction turnover layers along slope and placement of working bodies on a plow for plowing slope fields. The diagrams of the turnover of layers on the slope and the layout of the working bodies on the plow are given. It is proved that intermittent grooves ridges, according to agro technical requirements, it is necessary to rotate the layers downhill. It was found that when installing a cut-out spherical disk behind the front cases, a groove is formed above the a is under it. The subsequent layer wrapped in an even body. At the same time, rainwater is sub-arable of soil, which prevents water erosion. The results of one-factor experiments using strain-measuring methods are presented. It has been established that to ensure complete turnover of the layers within their own furrow by the hulls and the formation of the required ridges and intermittent grooves longitudinal distance between and toe even-numbered body ploughshare should be at least 110 cm.

The study aims to substantiate the design scheme of a linear plow with a disk angle. The authors have developed a linear plow with a disk plow for smooth, furrowless plowing. The proposed plow has disc lugs, screw housings, and guide plates. The technological scheme turnover of polygonal layers formed by disk pre-plates, the scheme mutual arrangement housings and guide plates, and the general view laboratory-field installation for conducting experiments are given. During the experiments, the degree of sealing plant residues, height irregularities on the surface arable land, and the traction resistance device were used to evaluate the performance plow. To ensure the required quality work with minimal traction resistance, a linear plow must be equipped with disc pre-lugs installed in front housings along their field cut line. When installing a disk prep lug with a working surface facing towards the turn formation, the degree sealing plant residues and the height of irregularities is 92-95% and 4.3-5 cm, respectively, which fully complies with agro technical requirements.
