Abstract: An earth working apparatus features a horizontally-oriented rigid support frame across a forward end of which is disposed a generally vertical scraper blade. Mounted forwardly of the frame is a roller. A holding device projects rearwardly from the frame and is pivotally coupled to a steerable motive vehicle in a manner which permits vertical swinging of the frame. A ram is disposed vertically above the holder. The ram is pivotally coupled at one end to the support frame and at the other end to the vehicle so as to effect swinging of the frame. Also pivotally mounted on the vehicle to swing vertically is an elevator linkage. The holder is pivotally coupled to a swinging end of that linkage and the ram is pivotally coupled thereto. Also mounted laterally across the support frame and forwardly of the scraper blade is a drag blade.
