The implement has a frame (9) with a wheel (10) having peripheral blades to cut the trench and motor driven. An extractor removes waste produced by cutting the trench. A carrier (16) is connected to the frame and encloses the external part (10A) of the wheel, situated outside the trench, to come into contact with the surface of the soil. Extracting suction heads (17) are connected to the carrier and can create a vacuum in the internal space (E) between the external part of the wheel and the implement, and evacuate the waste from the excavation. |
