Abstract
An apparatus for removing ballast utilizes a ditcher wheel to remove ballast from along the side of a railroad track. An undercutter is pivotally mounted to the frame of the ditcher wheel rearwardly thereof and is also pivotal about a vertical axis such that the undercutter may be placed beneath the track while supported by the ditcher wheel. A portion of the undercutter is aligned parallel to the track proximal and rearwardly of the ditcher wheel and serves to urge the ballast removed by the undercutter into the path of the ditcher wheel for removal.
