ABSTRACT:
A surface finishing tool for a backhoe comprising a pair of arms which are pivoted on the brackets which extend along the back of the bucket so as to depend therefrom. A scraper of approximately the width of the bracket is welded across the ends of the arms and a stop bar on the arms engages the brackets when the bucket is in its load-carrying position whereby the bucket may be pulled to drag the scraper along the surface. When in the raking or digging positions the arms merely hang down along the back of the bucket with the scraper blade free of engagement with ground.
