Abstract
The article presents the effect of using a tillage tool with skimmers, second stage skimmers, and bodies (double-deck plow) on the reduction of traction resistance and energy consumption by at least 1.1 kN, i.e., 3.3%. In addition, the statistical characteristics of the plowing depth and the width of the longitudinal profile of the field are stabilized. The use of agricultural machinery with skimmers, secondary skimmers, or bodies ensures even distribution of plowing depth fluctuations. The use of a plow without skimmers mounted on it leads to a regular and significant increase in the spread of fluctuations in the working depth and cross-section of the field. The normalized correlation function of this process is characterized by the presence of a noticeably marked periodic component. When the plow is used without skimmers mounted on it, the working period of the unit practically corresponds to the working width of the tillage tool. The use of skimmers with a grinding angle of 25° causes its deformation in the soil environment, which results in stratification, not shearing. This ensures a statistically significant and regular decrease in the traction resistance of the plow.
