Pintle hook hitches with ball mounts are specialty mounts that convert a pintle hitch and a ball coupler into a multipurpose tool. To use the pintle hook, attach the hook to a lunette ring to tow one or more trailers. To use the ball coupler, open the hook and attach the coupler to the hitch ball directly. Some ball mounts come with interchangeable parts to match ball couplers of different sizes.
