Abstract
An attachment, adapted to mount to the front edge of an excavating bucket, includes a working structure and a base. The front edge of the bucket defines an inner surface, an outer surface, and a beveled surface oriented at an inclination to the inner and outer surfaces. The base of the attachment includes a single leg or pair of legs having opposed engagement surfaces. The engagement surfaces on the two legged attachments diverge from one another to define a gap therebetween for receiving the lip of the bucket. One of the engagement surfaces defines a convex surface which enables the attachment to be mounted to a variety of different buckets irrespective of the inclination of the beveled surface of the front edge.
