Abstract: The present invention concerns a bucket, an excavator including the bucket and method of construction of the bucket. In one form, the bucket includes an attachment portion for attachment of the bucket to the machine; and a containment portion mounted to the attachment portion, said containment portion defined by a base wall, an opposed top wall, a pair of opposed sidewalls and a rear wall, each of the base wall, the top wall and the opposed sidewalls having an outer edge and extending from the rear wall to the outer edge to define an opening to the containment portion. The bucket further includes a reinforcing formation extending across an outer surface of the top wall and at least an adjacent portion of each sidewall of the containment portion, said reinforcing formation having an arcuate shape that transitions into, and at least partially defines, a corner between the top wall and each sidewall to reinforce a join between the top wall and the sidewall and enhance rigidity of the bucket.
