Abstract

A trenching attachment is provided. The trenching attachment includes a cutting tool and an indication structure that is operable to set a depth of the cutting tool relative to the rails of a railroad track. The indication structure and cutting tool are movable at least about a first, second, and a third axis to align the trenching attachment with a crib used to contain a railroad tie.
