No aware of any. You have a couple options for sleeve hitches though: the Cub Cadet super-expensive (but really nice) one for about $950, or the JohnnyProducts one for about $575.
I am building my own....for a 2176 hydro and 3186 hydro....it will cost a few bucks to do it but will not be as expensive as the Cub factory ones ($899.99 for the 3186)...I will have about $275.00 in mine most is for the 3 pt hitch parts and hydro cylinder and control valve...links-USA has the hitch parts on e-bay and Bailey Hydraulic Cylinders Manufacturer has the best cylinders and a good price to boot!
