I bought an off topic (MTD) tractor from Builder's Square in 1996 because that's what I could afford at the time. Today I replaced the plastic ring gear that broke on Sunday. Except for changing oil and batteries that is the absolute first thing I had to do to this tractor. Still has the original belts. I never expected it to last this long. Borrowed the neighbor's 2 year old big box green tractor to mow after my ring gear broke broke and it mowed like crap and seemed very cheap. I thought about getting rid of the MTD when I get my deck for the 1250 done but I might keep it around. Probably wouldn't get much for it. I don't think workmanship is the problem. The assemblers can only put together what they are given.
