FIELD: agriculture.;SUBSTANCE: machine comprises frame, to which body of multi-shaft cylindrical reducer is fixed, and mechanism of rotation control, providing for body rotation by 180° when stem is treated. Body is arranged with supports and dampers at the opposite ends and milling drums at vertical output shafts. Body is arranged with the possibility to rotate around central driving shaft. Mechanism to control body rotation is arranged in the form of spring-loaded feeler with pusher, finger and two cams. Finger is movably inserted in bushing fixed onto frame. Cams are located symmetrically relative to axis on upper surface of vessel. Control mechanism is equipped with electric system, comprising electromagnet, intermediate relay and two switches. Electromagnet is kinematically connected to finger. One switch is kinematically connected via pusher with feeler, and other alternately interacts with cams as body rotates. Electromagnet has device to block electric contacts of switch connected to feeler.;EFFECT: invention will make it possible to treat garden undertree area without damage to tree stems, and also to increase device reliability.;3 dwg
