An injecting ripper comprises a frame with a mounted device, a central knife, a ripper point, a tank for chemical substances with a sowing unit with a doser and a toxic-matter tube, a coverer. The central knife is arranged at an obtuse angle to the moving direction of the unit. An electric motor of direct current is used as a drive of the sowing unit in such a manner as to allow regulating the number of rotations by means of changing the voltage pattern in a system of electrical power supply thereof. |
