ABSTRACT:
An attachment is provided for selectively operating one of a variety of tools for removable attachment to the arm of a backhoe machine from which the bucket has been removed. One of the tools may have a first portion movable with respect to a second portion. Each of the tools are mounted to a rigid bar, any one of which is alternatively insertable into one end of a frame fittable on the backhoe arm. The backhoe includes a hydraulic cylinder disposed along the arm for pivoting the bucket when attached, and the attachment is provided with a sliding member connectable with the end of the cylinder for movement thereby along the attachment frame. A guide member directs the sliding member along the length of the frame. A lever is pivotally attachable at one end to a movable portion of the movable tool, and is pivotally attachable at an opposite end to the sliding member when the tool is secured in place along the frame.
