Starting 3rd summer on FT SD 54, 276 hours. Was mowing tonight and all of a sudden the mower jerked to the left. Stopped and got off the mower to find the tire going flat and the center broke out of the rim. Not a happy camper! Looked at the right side and the rim on that side is starting to crack as well. Mower is not abused in anyway and still looks new. This mower has been a lemon since I bought it, oil pump lost pressure, got that fixed then the bottom crank seal leaked like crazy, then the oil drain pipe gasket started leaking. The shop took care of it all but they have had this mower more than me. Has anyone else ran into this issue with the rims?
