A neighbor gave me an old broken riding mower. The transmission is broke. I took it apart and found whats broke but I can't find what transmission it is. The only markings on the casing is "MTD". On the mower itself, under the seat, is model# 189-465-084 C309D and
serial# 41-010 9485. Can anyone give some guidance where and how to identify this machine, transmission and where to find parts?
