ABSTRACT:
A self propelled apparatus for digging a shallow trench along one side of a roadway is disclosed, and which is useful as part of a roadway widening operation. The apparatus comprises a cutter drum mounted to one side of the chassis of the apparatus, and a conveyor belt is mounted to the same side of the chassis with an inlet end positioned immediately adjacent the cutter drum and an elevated outlet end positioned beyond the forward end of the chassis. An enclosure surrounds the cutter drum so that the drum may be rotated in a downwardly cutting direction, and the loosened soil or other material may be lifted and guided around the drum and deposited onto the conveyor. The cutter drum includes one or more extensions which may be coaxially mounted thereto, so as to permit the width of the cutter drum and thus the width of the resulting trench to be selectively varied.
