A B S T R A C T A bucket-wheel for loosening and picking up material carries a plurality of buckets distributed peripherally and provided, at the cutting corners, with oscillating impact- cutting edges. When the said bucket-wheel, mounted upon a boom, pivots, these cutting edges must perform special cutting work in order to loosen the material. Each activat- able impact-cutting edge is therefore arranged at the cutting edge of the bucket and of the pre-cutter. The impact-cutting edge may be accommodated, with its shaft, in a bush in a cutter-carrier where it is protected. Actuation may be effected by an adjacent striker under the action of a pressure- medium. Pins prevent the impact-cutting edges from rotating in the cutter-carrier. A limiting device may be provided so that only those strikers which must actually carry out cutting work are acted upon by the pressure-medium, the other strikers being separated from the system by a pressure- medium control.
