  • Patent number: 11135710
    Abstract: The ‘Compact Excavator & Skid Steer Loader Auxiliary Hydraulic Coupler Installer Tool’ is designed as a handheld tool for the purpose of mechanically installing high pressure auxiliary hydraulic attachment couplings on Compact Excavators & Skid Steer Loaders. The uniqueness of the tool is that it provides a safe, clean, fast and simple alternative to the use of hand wrenches, drip pans, rags and additional environmental cleanup materials that are required when attaching hydraulically driven auxiliary attachments to compact excavators and skid steer loaders. The tool consists of 4 basic components. The handle, anchor, attachment head and forcing head. The single anchor tool handle provides the base from which multiple tools can be configured to fit any attachment or machine application by using one of the 2 anchors and one of the 3 attachment heads with one of the 3 forcing heads.
