The article presents the methods and results of bionic modeling in agricultural mechanics, which made it possible to substantiate models of the working bodies of asymmetric flat-cutting paws adapted to the soil environment using the simulation of the burrowing foot of the common dung beetle (Geotrupes stercorarius). The solution of problems of improving the shapes of flat-cutting working bodies is proposed on the basis of the use of a mechanic-bionic approach, which allows analytically describe the geometric shape of their blade and rational values of oscillations in the horizontal plane. The experimental model of the working body with asymmetric flat-cutting paws reduces the traction resistance by 8 … 12%, in comparison with the serial model CFA-3.8. This is ensured by the optimal ratio of the working widths of the left and right flat-cutting knives, which ensure the stability of the course in depth and in the horizontal plane with the best agricultural performance.
