Abstract
A device for attaching various earth-working tools to a bucket of excavating equipment, such as a front-end loader, backhoe, or excavator. A frame has two spaced parallel plates, each having a wedge-shaped notch on one side. A stabilizing bar, adjacent to the open end of the notches, connects the plates. The tool, such as an asphalt roller or cutter, is attached to the bottom of the frame between the plates. At the top of the frame, a clamping mechanism, having a pivoting arm, is mounted between the plates. To use the device, the excavator bucket is inserted into the wedge-shaped notch, with the device holding the bucket in place against the edges of the wedge-shaped notch, the stabilizing bar, and the pivoting arm of the clamping mechanism.
