Abstract

From an environmental perspective, the article presents results of theoretical studies to justify parameters and the angle of entry into the soil of ripper tooth, and width and length of the working surface of the ripper tooth of combined unit. Graphs of changes in the working surface length of the ripper tooth depend on the angle of entry of the tooth into the soil at different values of tillage depth and width of combined soil-cultivating unit for minimum tillage, to ensure high-quality loosening of the soil at minimum energy consumption. Based on the results of theoretical and experimental studies in the field of soil science and agriculture, a scheme for placing working bodies on the frame of a combined soil-cultivating unit for minimal tillage has been developed, which contributes to increasing soil fertility with minimal energy and labor costs.
