coefficient of volumetric crumpling of the soil depending on the crumpling rate, s/m, Э ϑ - the rate of crushing of the soil by the occipital chamfer in the vertical direction m /s . According to research [13] we will be able to record (13) where, a – depth of tillage, m; 0 ρ and ρ - soil density before and after treatment, kg/m 3 . Given the expression we get (14) or (15) Using the formula (15), it is possible to analyze the change in the reaction of the soil to the occipital chamfer depending on its main parameters. As noted above, the stability of the plow stroke in depth is violated if the condition is not met . (16) Substituting the values y P and y R into the formula (16) and after some transformations, we obtain a mathematical model of the change in the depth of plowing. (17) If we take into account that the stability of maintaining a given processing depth is determined by the suitability of the ploughshare for further operation, then it can be seen from formula (17) that the main influencing factor on the processing depth is the physical and mechanical properties of the soil and the geometric parameters of the blade. The resource of the ploughshare according to the constructive factor is determined by the formula [14] (18) where n hh , 0 – initial and maximum wear width of the part; dt dh – intensity of blade width change. If we use the value of the average rate of wear, the resource of the working body is as follows (19) After substituting the value of I from formula (7) into formula (13), we get (20) If in formula (20), instead of P and R , substitute their values from formulas (11) and (12), taking into account the value h д [15] (21) h s = l s × sinε R= + . , . .
