An injector is provided at a lower portion of the blade. The frame is moved by a tractor, cutting the soil. Compressed air is injected from the injector into the soil for loosening the soil. Orifices for air injection are located at a narrowed neck of the injector for protection from soil clogging and escape of compressed air.
