The article alleges equation for the movement of soil particles on the working surface of the working bodies (knives), a vertically-rotary tillage body actively driven. Soil particles are treated as a material point moving in a plane perpendicular to the axis of rotation of the blade. It is assumed that the shape of the knife is arbitrary and is set to smooth planar curve in the plane of movement of material point. Certain power is needed to overcome the friction between the soil particle and the surface of the working body.
