I have a Craftsman 5.5HP 21" Multi-cut push mower, not self propelled. The right front wheel is sticking. I bought a replacement part and when you tighten up the nut that holds on the wheel, it becomes locked just kike the original was doing. It will not turn after about 5 minutes of mowing. Just started after about 10 years of use. Does not make sense to me.
