Abstract
The article presents the methods and results of bionic modeling in agricultural mechanics, which made it possible to justify models of working bodies adapted to the soil environment: a tillage ring-cutting roller using modeling of a digging foot of the rhinoceros beetle; a spring soil leveler, where the burrowing limbs of the mole cricket (Gryllotalpa) are used; a stubble cultivator, in the likeness of the forms of a burrowing limb of the scarab beetle (Scarabaeus). The analysis of the results of the tests shows that all the models of working bodies of machines for surface tillage, created by the method of bionic modeling, show a significant decrease in traction resistance in comparison with serial working bodies.
