The article substantiates the characteristic bending points of blade operating body of the geokhod. The urgency of the research is considered. The information on the work peculiarities of the operating body of the geokhod is given. The method of calculation of the blade operating body of the geokhod is described, in particular, the entire force of the blocked cutting by a single radial blade of the IO of the geokhod is shown, and this force is also represented as a sum of three constituent forces. To establish the purpose and objectives of the study, it is justified to choose the force to overcome the soil resistance by the front face of the blade Pcv, which is proportional to the cross-sectional area of the slot before the front edge of the knife and which depends on the angle and strength of the soil. The limits of integration of the projection of the component of the soil resistance force into the cutting, depending on the width of the cut, on the axis of rotation of the geokhod P0.cvand on the plane perpendicular to the axis of rotation of the RIO.CV. Based on the study, the tasks for further research have been determined.
