FIELD: agricultural production, in particular, plant growing. ^ SUBSTANCE: apparatus has device for measuring area of stem section and working tools. On the basis of measurements, voltage supplied to working tools is adjusted. Optimal conditions are created for plant treatment regardless of diameter of stems. Also, power consumption is reduced owing to employment of end switches adapted for automatic switching-off of power units of working tools in case of "idle stroke". ^ EFFECT: increased efficiency and reduced power consumption. ^ 2 dwg |
