I had the same problem. There is a groove in the tire bearing and on the axle stem where your tire goes on. Wherever you changed your tire, look for a long piece of metal or something. It is placed in those grooves to stabalize the tire on the stem. If it is not there, it will just turn and your tractor will seem like it's screwed.
