    摘要： An excavating machine of the type including a chassis and a digging unit mounted for digging movement thereon. The unit comprising an endless wheellike member and a plurality of peripherally spaced sets of laterally staggered tooth members detachably mounted in angularly oriented relation on the wheellike member for moving excavated material upwardly and outwardly of the digging unit. The body of each tooth member having leading and trailing ends and inner and outer edges extending therebetween, and including an attachment portion adjacent the leading and trailing ends, and a blade portion made integral therewith adjacent the leading end and outer edge thereof. A plow assembly is mounted for selective directional adjustment on the chassis and includes an angularly oriented winglike scraper construction operative on opposed sides of the digging unit for moving excavated material away from the digging unit.
