In southern zone of cotton growing with insufficient moisture, one of the leading places is occupied by develop tools which simultaneously execute the technology trial of forming ridges and prepare them to display cotton. The purpose of research confirms design and the width gripper roller with elastic stems. Constructive scheme of the comb-maker with the roller-comb-makers is given. The proposed design scheme of the machine includes sequentially installed comb-makers and rollers-comb-makers. Analytic dependencies and mathematic patterns were obtained to define the width gripping roller of comb-forming machine. Theoretical and experimental studies have established that to ensure that the soil is prepared for sowing cotton on the ridges with minimum power consumption, width the gripping roller of the comb-forming machine should be at least 60 cm.

A design diagram of comb formation roller in resilient stems is given. Comb-forming roller consists of support and small discs, as well as elastic rods. Elastic rods are installed along the perimeter of the diameter of the disks through their holes. Analytical dependences and mathematical models are obtained for determining the distance between disks, the diameter of disks, the diameter, length and number of elastic rods. One-factor experiments were carried out to substantiate the diameter of the disks and the number of rods. It was found that with the length of the elastic rods of the comb-forming roller 65-75 cm, the diameters of large, medium and small discs, respectively, at least 600mm, 550 mm and 200 mm, the angle of sharpening of the discs within 55-650, the issue of stems within 64 - 69 trimming and diameter bars 3 mm, intensive defeat of chunk and high- quality creation of ridges is ensured.

The research was carried out with the aim of theoretically determining the traction resistance of a rotary tillage tool for pre-sowing soil cultivation. When developing theoretical prerequisites, we used the results of previous studies by various authors, as well as a rational formula proposed by Academician V.P. Goryachkin to determine the traction resistance of the plow. The traction resistance Pt of the rotary tillage tool is made up of the traction resistance of the spiral-screw working body ( ) and the traction resistance of the section of ellipsoidal needle discs ( ). In turn, the traction resistance depends on the forces of resistance of the soil to rolling, friction and crushing, the traction resistance consists of the forces of resistance of the soil to friction, cutting and throwing away. According to the final equation, the traction resistance of the rotary tillage tool depends on the design (the gravity of the spiral-screw working body, the diameters of the spiral-screw working body and ellipsoidal needle disks, the angle of inclination of the forming surface of the spiral-screw working body to the soil surface, the number of needles on the ellipsoidal disk , the angle of inclination of the hub of the elliptical needle disc to the axis of rotation, the number of elliptical needle discs in the section), kinematic (translational speed of the implement, cutting speed of the soil, the indicator of the kinematic mode), technological (width of the tool grasp, depth of soil mulching, width of soil shavings, number of needles simultaneously in the soil, the coefficient taking into account the surface roughness of the spiral-screw working body) parameters, as well as the physical, mechanical and technological properties of the soil (density, rolling resistance coefficient, sliding friction coefficient, coefficient of resistivity to cutting, coefficient of volumetric crushing, coefficient of rejection). The resulting expression can be used to determine the traction resistance of similar tillage machines and rotary-type implements
