In order to provide an articulated arm bucket excavator 10-11-18 with a remotely controlled ripper attachment, a ripper tooth 20 is rigidly secured on the web of a link 17 having end mounting sleeves so that the conventional bucket-tipping link can be replaced by the ripper link (17,20). In use the ripper link (17,20) connects the crowd arm (16) to the excavator bucket (18) so that the ripper (20) and bucket (18) are simultaneously attached to the end of the excavator arm (10,11). In the fully "crowded" position of the bucket (18) the ripper (20) is in its operational position for ripping the ground (24). Thus, bucket (18) or ripper (20) can be selected at will from the cab of the excavator by movement of the crowd arm (16). <IMAGE> |
