Abstract
The present invention is directed to an adjustable attachment for mounting a tool to a tow bar. A shank having first and second spaced parts has a bracket for attaching the first shank part to a tow bar in an operative position thereon so that the shank may follow the movement of a drawing vehicle. A structure is provided for attaching a tool to the second shank part. The second shank part, with a tool attached thereto, is spaced below the first shank part with the tool in its operative position. A pivotal joint joins the first and second shank parts. At least one threaded bolt having a threaded shaft with two ends and a head at one end and a free end at the other end threadably engages a threaded receptacle. The threaded receptacle is positioned such that the free end of the shaft prevents the pivoting of the second shank part in at least one of a clockwise or counter-clockwise direction.
