A schematic diagram of the robotization of a wheeled tractor of traction class 3 is given. It is shown that «Agropilot» precision agriculture system ensures driving accuracy no worse than ± 0,05 m, the «Edelweiss» modular unified technical vision system allows to control an autonomous platform. The automated control system for shifting gears and ranges can operate in one of three modes: full automatic, semi-automatic and manual. The upper-level onboard information and control system provides automatic control of the machine-tractor unit in unmanned mode throughout the shift work. The influence of the technical level of the tractor on its performance, working speed and shift factor is considered. As a result of studies of the influence of the technical level of the tractor elements on the shift performance, it has been revealed that the design of the tractor can give an increase in productivity to 37,2 %.
