The article analyzes the technical means for uprooting trees. Tools aggregated with wheel and caterpillar tractors of various traction classes are the most popular ones in Russia. Abroad, self-propelled stump removers with high engine power and high performance are used, which are in demand in various industries (forestry, agricultural and oil and gas complexes, road construction), when laying high-voltage power lines and their maintenance, as well as in other areas of the national economy. The analysis of technical means for uprooting trees has shown that the dominant trend is creation of stump removers that ensure safety of the process, its high productivity and decrease in the number of personnel on felling. Self-propelled robotic stump remover equipped with wide-profile low-pressure tires has been developed to implement innovative technologies in the forest complex. Ensuring the technological process is carried out by robot-eradicator in unmanned mode. It is achieved by using a technical vision system, navigation equipment, automated control of technological equipment, transmission and steering. The aim of the study was to evaluate the longitudinal stability of a robotic self-propelled stump remover during vertical transportation of a tree and environmental compatibility of its wheeled mover with soil and vegetation cover. Conducted theoretical studies have found that the proposed layout scheme of a self-propelled stump remover provides longitudinal stability when moving with a tree in an upright position without the use of ballast counterweights behind the rear axle. It was also found that the wheel mover of the stump remover equipped with wide-profile low-pressure tires is environmentally friendly when performing technological operations in the summer-autumn period
