I have an 1811 which is almost the same as your tractor and I would say $200-$300 minimum. Just the sleeve hitch and parts for it are usually over a hundred dollars. The necessary parts are the actuator arm that bolts to the rear end, the frankestien bolts, the rear end bracket, the lift rod, the two lift pieces for the hitch and then you will need the long rod that goes from the ram to the rear of the tractor and the little attachment bracket that goes with it. I bought mine from ebay and the guy sold me the wrong one but one of our forum members need it so it worked out. Be careful because people will sell you stuff that you cannot use. If you can find the exact dimensions of the long rod and the angle in it it will save you some time. If were you I would buy the whole kit from one of our sponsors and you will be way ahead.
BTW, I live in Tyrone GA and if you are anywhere near I would be glad to show you all of the pieces.
