Abstract

A dividing cutting machine includes a cutter boom pivotable about a horizontal axis, at least one cutter head disposed on the cutter boom, a loader deck hingedly connected to the frame of the dividing cutting machine pivotable about a horizontal axis and provided with movable gathering arms for continuously sweeping the mined material upwardly over the loader deck to conveying means. Stops mounted on the cutter boom and on the loader deck at locations spaced from their respective horizontal pivot axes have a height which precludes physical contact between the cutter boom and the gathering arms in each mutual pivotal position.
