ABSTRACT:
A trench digger for digging and maintaining drainage ditches along railway road beds. The trench digger includes a compact rotary drum cutting head mounted on a boom that can be swung about a boom base pivot axis to position the cutting head to either side of a railroad mounted support carriage. A first conveyor carries loosened composite from the cutting head to a first conveyor discharge point rearwardly of the boom base pivot axis. A second conveyor, pivotally mounted to the boom base at a second conveyor pivot axis oriented rearwardly of the boom base pivot axis, receives the loosened composite from the first conveyor and conveys the loosened composite to a second conveyor discharge point remote from the boom base.
