IMPROVING DIRECTIONAL STABILITY OF TOOLS USED FOR CULTIVATING ROW COPS

Positioning of a land cultivation unit on the fi eld determined by the specifi c location of its working tools is one of the precision farming criteria used in the cultivation of row crops. The navigation system provides reference-input signals as it determines the position of the machine-tractor unit (MTU) and its implements. When the MTU moves along the treated fi eld surface, its tools deviate from their trajectory due to the difference in density and soil moisture, as well as local inclines. The authors present a controlled mounted implement UNU-2, which together with the navigation system installed on the tractor allows determining the location and course position relative to the coordinates specifi ed by the navigation system. The paper also presents characteristics and operating principle of the device. Using the controllable mounted implement will allow positioning and changing the inclination angle of the tool on the prescribed fl at horizontal surface. This will ensure high accuracy of operations performed by the MTU, increase its technical performance level, and reduce labor costs. Thus, the use of tractors and controllable mounted implement based on navigation systems ensures the accuracy and effi ciency of such technological operations as planting and cultivating
of row crops. The development of a technical device for adjusting the trajectory of mounted implements increases the effi ciency of the MTU operation.
