Don't know of any but will keep my eyes open. Since you posted this in the Toolcat forum, are you planning on hooking to a Toolcat? If so be advised a 48" Bobcat soil conditioner has a narrower Bobtach hook up than the Toolcat. This soil conditioner was built for use on the walk behind track machines (MT52 & 55) and smallest skid-loader they make (was 463, now S-70).
