William Wittenmyer had been the former sales manager of Buckeye Traction Ditcher Co. Additions were received in September and November 1988 from Mrs. Wittenmyer. No restrictions exist on the use of this collection.
Duplication is permitted for the purposes of preservation and research.
Preliminary processing of the collection was done by Chris Haley in 1985. The register was completed by Marilyn Levinson, Curator of Manuscripts in April 1995. The company discontinued production in Findlay in 1973, although Ohio Locomotive Crane Company of Bucyrus is manufacturing a version of the machine. The revolutionary design of the ditcher digging wheel had neither an axle nor spokes, enabling the machine to dig a deeper trench that was uniform in size and grade. In 1988 the American Society of Mechanical Engineers designated an early model of the ditcher, No.88, in the possession of the Hancock Historical Museum, an International Historic Mechanical Engineering Landmark.
