Abstract
An earthworking device such as a power scraper has a cutting edge assembly which may be mounted to give either a straight or a crenellated edge. The assembly consists of several identical long, narrow, rectangular members which have chamfered longitudinal marginal portions and are mounted alternately with the chamfers facing up and facing down, and the latter chamfers overlying the former. Threaded bolts impale holes near one end of the members which have their chamfers down so as to secure those members to the top surface of the scraper blade and frictionally clamp the other members to the blade.
