So recently the small front wheel on my small Craftsman rider (Model 536.270320) somehow split the center section off. No biggie, I just grabbed my welder and welded it back together, but in my haste I forgot to remove the center plastic/nylon bushings and melted them a little bit. Over the past couple weeks they've finally rounded out, so the mower is pretty much down. Looked on Sears website and found a replacement assembly, but it is over $90 with shipping! The part number on their site is 1401381-601, and a quick Google search has proven unsuccessful. It brought up a couple Husqvarna wheels, but they look different. Anybody know if I can get something similar and/or cheaper? I only plan on having this mower for another year and do not want to put any more money into this thing. Already planned to have a new mower at this point, but it never worked out...
