In a grubber implement designed for deep loosening of soil by means of a downward projecting tooth 16, which is fitted on a tractor lift-borne chassis 2, the tooth 16 is angularly adjustable with power-assistance by means of a hydraulic cylinder 24, even whilst performing grubbing work. The tooth 16 assumes a pronounced downward and forward inclined position, as a result of which significant advantages are achieved in terms both of the low tractive effort required and the quality of the soil working. The power-assisted pivotable tooth 16 also makes the implement suitable for other relevant purposes. <IMAGE>
