ABSTRACT:
A combination spacer and lifting device for backhoe machinery, wherein the device includes a spacer defined by an elongated tubular sleeve member which may be formed to have an extended tab member fixedly attached thereto. The sleeve member is positioned as a spacer between the hydraulic-cylinder link members, and is rotatably mounted on the link pin which pivotally connects the link members to the bucket of the backhoe. A hook member is connected to the extended tab member of the sleeve, providing a means by which a chain, cable or the like can be readily attached so as to carry or lift a given load or structure; and the hook is oriented to prevent interference with a bucket lifting arm.
