ABSTRACT:
Earth moving equipment for cutting into the earth employs a container having a forward opening. A holder is mounted in front of the container opening about in the middle thereof. A milling device is mounted on the holder for cutting into the earth. This milling device is positioned in front of the container for throwing cuttings into the container. The milling device includes right and left milling drums having respective axes subtending an obtuse angle with respect to each other. These milling drums each have a plurality of picks for cutting into the earth. The drums have a combined width exceeding that of the container so that the container can follow the milling device into locations cut out by said milling device. The milling drums are closely spaced to allow their picks to cut completely across their combined width without leaving an uncut region between the milling drums.
