ABSTRACT:
An excavating apparatus for breaking and removing material away from an upright face of material is disclosed. The apparatus includes a rotary cutting head mounted between the fore ends of a pair of boom arms. The boom arms are pivotally mounted relative to the front end of a vehicular portion of the apparatus. A shroud partially surrounds the cutting head for confining material cut from the face. The shroud includes an edge shoe portion for engaging the face and is pivotally mounted at the fore-end of the boom arms. The shroud is adapted for selective rearward pivotal movement as the boom arms are swung upwardly for maintaining the edge shoe portion against the face.
