When evaluating tillage machines, one of the important places is occupied by agrotechnical assessment of the quality of the technological process of tillage. The properties of the soil as an object of cultivation, as well as the processes occurring during the interaction of the soil with any materials, are studied by agricultural mechanics, created by V.P. Goryachkin. One of the most important characteristics of the soil condition is the hardness of the soil, or the resistance provided by the soil to the penetration of any deformer into it. This article describes the forces and stresses that occur when the plunger penetrates into the soil. According to the theoretical provisions, friction force F, drag force Q, total force P, stresses σ1 and hardness T are calculated, theoretical dependences of soil hardness on the tip diameter on compacted and loose soil are given.
