The technology of continuous lowering of stumps below the soil surface throughout the area of cutting is proposed to reduce the loads on the working bodies and frames of tillage tools and ensures complete mechanization of the reforestation process. A technological process has been developed to prepare stumps for lowering below the ground surface, which consists in creating platform-deepenings around stumps and cleaning their lateral surface from the soil within the depth of the platform. An aggregate for its implementation consisting of a tractor, a hydraulic manipulator, a screw rotator and a platform-maker with flexible working bodies has been designed. A mathematical model of the aggregate operation has been created. It enables to evaluate the efficiency of the manipulator placement of platform-maker and to determine the influence of the parameters of the hydraulic manipulator on the performance of the aggregate. The influences of the stump distribution density, the boom of the manipulator and the maximum angle of its rotation on the performance of the platform-maker have been determined. It was revealed that the productivity of the aggregate increases with an increase in the density of stump distribution on the cutting and the main geometrical parameters of the hydraulic manipulator.
