An excavating apparatus adapted for use with a grader, backhoe, loader or the like which includes an excavating implement supported from the end of a longitudinal member by an implement supporting means which is movable about a first pivot means having an axis extending in a direction transverse to the length of the longitudinal member. The excavating implement is mounted for movement about a second pivot means having an axis which extends in the plane of the longitudinal direction of the longitudinal member. The second pivot means extends between the implement supporting means and the lower part of the rear portion of the implement and this second pivot means is adjacent to the ground when the leading edge of the implement rests on the ground. The apparatus also includes means for moving the implement supporting means about the first pivot means and means for moving the implement about the second pivot means. In a preferred embodiment the means for moving the implement about the second pivot means includes a hydraulically operated reciprocating means, such as a cylinder and ram, which has one end pivotally attached to one of the excavating implement and the implement supporting means and the other end pivotally attached to the other of the implement and the implement supporting means. Also, preferably, at least the major portion of said means for moving the implement is located in the space between the rear portion of the excavating implement and the forward portion of the implement supporting means.
