ABSTRACT:
Two embodiments of a replaceable cutting edge assembly for earthmoving buckets, each assembly including a plurality of cutting edge sections arranged along a leading edge of the earthmoving bucket floor with digging teeth overlapping the junctures between the cutting edge sections, the cutting edge sections being configured for attachment to the bucket floor, for example, by means of bolts, while trapping and holding the digging teeth in place in order to facilitate replacement of individual portions of the assembly while also adapting the bucket for use with a single elongated cutting edge without the digging teeth. In one embodiment, the cutting edge sections and teeth are designed to provide a flush bottom surface suitable for finish work even with the teeth in place. In the second embodiment, additional means are employed to secure both the digging teeth and cutting edge sections in place along the leading edge of the bucket floor.
