ABSTRACT:
An improved, highly utilitarian bucket is described. The bucket incorporates two traversely spaced side walls connected by a backwall plate so as to form a generally scoop-shaped enclosure. The leading edge of the backwall is provided with a one-piece cutting-edge plate disposed between the side walls and formed with a plurality of tangs along its leading edge. The tangs are adapted to removably carry a plurality of generally flat tooth-plates. Each tooth-plate defines two oppositely disposed beveled edges. Because of the symmetric nature of the tooth-plates, they may be reversed to extend, if not double their useful life. Several embodiments of the tooth-plates are described. In addition, the bucket is particularly adaptable to serve as a mount for a easily connected back-fill blade.
