“…It should be noted that the use of the above-mentioned working bodies contributes to an increase in energy costs for tillage. Most of the scientific research is aimed at improving the geometric shape of the working bodies themselves, which does not give a sufficient result in view of the destruction of the plow sole, although it has some effect in terms of creating an agronomically valuable soil structure [17][18][19]. The scientific research [20] proves that the cultivation units with skimmers, second-row skimmers or other bodies creates an acceptable soil structure and partially destroys plow soles.…”

Technogenic influence on agricultural soils leads to the transformation of their morphological features, significantly worsens their agrochemical, physical, mechanical and agrotechnological properties, prevents the optimal use of potential soil fertility and, as a result, leads to a decrease in crop yield. Mechanical soil decompaction when using various types of subsoilers, including the flexible chain-type working body (the chain), is used to prevent the negative consequences of technogenic influence. According to the results of the analytical calculations, the proportionality factor of the chain length, which determines the ratio of the width of the plow grip to the chain length of a flexible subsoiler, was established. The specified coefficient is proportional and equals 2.4. The use of the specified coefficient allows us, at the stage of the development of the design and technological documentation, to determine the main design parameter of the flexible subsoiler, which is the length of the used chain depending on the width of the plow grip. The surface of the field cultivated with the experimental tillage tool meets the requirements for sowing the agricultural crops without performing additional technological operations.
