This invention concerns an implement for a hydraulic excavator comprising essentially a ripper and a scoop wherein these implements may independently fulfill their respective operations while both are mounted on the dipper arm. The scoop may be swung rearwardly behind the ripper when the latter is in use and will form part of the face of the scoop when the scoop is in use. Relative movement between the scoop and ripper is effected essentially by an auxilliary hydraulic piston and cylinder assembly on the excavator.
