I designed and had fabricated this electric sleeve hitch using a craftsman hitch and other parts for my John Deere LT 155. Sadly, my Deere has been retired with a broken rod in the unrepairable Kohler and I have purchased another tractor that will not accept the sleeve hitch. I have a 42" blade and a trailer hitch ball mount for it and it will accept any standard sleeve hitch implements. Should fit any LT series tractor and probably many others. The spread between the arms of the hitch is about 12.75". I have included two photos of the unit on the Deere. Also includes a control switch for dashboard mount. I have about $475 in it. I can take $350. Let me know through the Forum.
