In article process of design of soil-cultivating tools on the basis of creation of their solid-state models by means of CAD is considered. Examples of use of system of solid-state modeling of SolidWorks and the package of engineering calculations of COSMOS integrated with it for the solution of a specific objective on justification of design data of the combined working body working in the conditions of existence of obstacles in the soil are given.Data of the kinematic and dynamic analysis allowing to establish forces arising on working bodies and links of the safety mechanism, at various options of interaction with an obstacle are provided. Are submitted data of results of laboratory researches, over real working bodies allowing to check reliability of researches of solid-state models of working bodies appendices for engineering calculations. Divergences on the maximum values of traction resistance of section of a cultivator when overcoming an obstacle made no more than 3,9%. The conclusion about applicability of means of CAD and reliability of the received results is drawn.
