The article deals with the dynamic analysis of the motocultivator motor load considering structural peculiarities of the milling work tools and their interaction with the soil. The authors describe the application areas of milling cultivators produced by domestic and foreign manufacturers. The features of the design of the milling work tools and the shortcomings leading to increased costs of power, the loss of productivity and quality of soil treatment are described. To find out the causes of reduced efficiency and establish the most optimal modes for motocultivators adjusted for the structural features of the work tools and specific soil conditions the authors have carried out a detailed analysis of the design of milling work tools of the motocultivator NEVA MK-200. The analysis includes the determination of the order and calculation of the operating angle for the interaction of the blades with the soil. The dynamic analysis has been carried out by the known semigraphical methods for one working cycle, which is equal one complete revolution of milling drums in the normal course of technological process of cutting the soil; the relations between the maximum torque and the power required to drive a knife have been calculated. The dynamic analysis has been also used to evaluate the total average torque of the drive shaft of milling drums. The analytical and graphical dependences of the engine power required to drive its work tools have been determined in view of the soil condition, structural and technological features of the functioning of the milling motocultivators. Processing the values of graphical dependences of the required engine power made it possible to establish its approximated functions. Based on the said functions, the authors have determined optimal and critical operation modes for motocultivators depending on configuration of milling work tools and soil penetration index when the engine operates under full load conditions.
