ABSTRACT:
A mobile milling machine for milling a road surface includes a floating mold board for directing milled material onto a loading device positioned behind the machine. The mold board has fixed thereto a holder for the loading device. The loading device is pivotable side-to-side about a vertical axis, with respect to the holder. The mold board, the holder and the loading device are vertically movable a limited distance between a top and bottom stop position, and pivotable about a horizontal axis at the top stop position, to expose the milling roller for repairs. When the machine is in operation, the mold board, the holder and the loading device are hydraulically supported to permit the mold board to float along the milled surface in a grazing contact.
