An improved tool adapted for attachment to a double pin mounting structure of the type that is commonly employed on excavator or backhoe type machines or vehicles. The improved tool is a bucket assembly with a grapple-like tine assembly mounted thereto and controlled by hydraulic actuators. The bucket assembly is mounted to a boom of a backhoe, for example, utilizing a single assembly composed of a hydraulic actuator and coupling members to attach to the double pin mounting structure on the tool. The bucket assembly is mounted on the boom to provide extended movement relative to the boom, and the grapple-like tine assembly is mounted to the bucket assembly for full closure and to enable near full opening relative to the bucket assembly. The tine assembly may be actuated by a pair of hydraulic actuators mounted adjacent one or both sides of the bucket assembly via a free floating bell crank for each pair of hydraulic actuators.
