The purpose of the research is to develop a device that can give an idea about changing the power parameters of tillage tool in all three planes of projections for the unsteady motion of the tractor with a tillage tool. This method is based on the model of force interaction of tillage implements with the soil, suggested by Professor L.V. Gyachev. The article is devoted to the study of power parameters of passive, active, and rotational tilling tool. A setup was designed to measure power parameters of tillage tool in three planes of projections. The installation to determine the power parameters of the tillage tool includes the following basic elements: soil channel, traction trolley, attachments and devices for converting of electrical signal and recording of the measured values. The sensors include: force sensors in linkage bars and sensors of working body movement. Electrical signals from sensors are served on an analog input module. Then the signals are supplied to the inverter interface. Next, the signals are processed on a computer. In the experiment, the tillage tool is set in various positions relative to the main (straight) movement, recorded are the parameters characterizing the coordinates (function arguments) and forces in the linkage (functions). Then the characteristics of the main force vector and main torque of the forces resultant of tillage tool interaction with soil are calculated. The results of several measurements are approximated by the curve most appropriate to the nature of the interaction. The obtained data are used in the study of stability, oscillations and dynamics of non-steady motion of tillers and tractor units.soiltillage toolforce interactionthe dynamicsstabilityfluctuationsпочварабочий органсиловое взаимодействиединамикаустойчивостьколебания[Бартенев И.М., Кургалин С.Д., Туровский Я.А., Лысыч М.Н.
