FIELD: agriculture and mechanical engineering, in particular, weedage controlling equipment. ^ SUBSTANCE: apparatus has working tool carrier frame, isolation plate located on frame and equipped with active members arranged in several rows at different heights. Length of section of each subsequent row of active members is greater than length of section of previous row of active members in the course of advancement of tractor. Row of active members is made in the form of sections connected in parallel and joined with feeding busbar which may be switched to control and protection unit. Each section is formed as U-shaped bar with attachment. Planes of rows of active members are arranged at an acute angle to plane of mower. Working tool of apparatus is equipped with mechanical mower located forward of active members. Carrier frame attachment means for attaching frame to transport means is provided with hydraulic cylinder for leveling of soil irregularities during operation of apparatus. Control and protection unit consists of generator, voltage increasing device, and voltage reducing device, said parts of control and protection unit being connected in series. Voltage reducing device is connected through control unit to voltage regulator. ^ EFFECT: enhanced reliability in operation, increased velocity and effectiveness of weedage control. ^ 4 cl, 3 dwg |
