Abstract: 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.
