:confused: My brother recently gave me a riding mower that runs really good.And me or my brother have no idea what kind of mower it is.It has a B/S 18 HP Twin head on it.The model # on the frame is 45160000 serial # 007406 and the code is 9222. I looked on the net and I guess it's an older mower but can't find it.If someone can help it would be thankfully.
