I have a Central Park 16HP 42" 6 Speed Model # 1248502. I was mowing and heard a loud clank. The motor runs fine but the mower stopped moving. I looked under the mower and a gear is partially hanging out of the bottom in the rear of the mower. I assume this is the transaxle model #930-055. I am curious what transaxles are compatable with this model. I dont have the funds to buy a new one but have found used on craigslist for $75 but I am not sure what models are compatable with mine. Is this even worth fixing or should I look for a new one? Thank you.
