Abstract
An implement adapter for providing excavation versatility that couples with and attaches to an excavation tool assembly for mounting a working implement thereon. The implement adapter comprises a frame for holding a working implement, wherein the frame is coupled and semi-fixedly attached to an excavation tool assembly. A parking projection holds the coupling element of the frame at a sufficient height above a surface when the implement adapter is detached from the excavation tool assembly and supported on the surface by the parking projection and a lowermost portion of either the frame or the working implement. The height at which the coupling portion is held by the parking projection enables engagement of the coupling portion with a cooperative coupling element on the excavation tool assembly without the need for any manual assistance. Additionally, the implement adapter has sliding and rotating connecting elements capable of connection to various sizes of excavation tools via manual or remotely actuated fastening mechanisms.
