I recently purchased 14 mowers from an old small engines repair shop for $140 bucks $10 bucks a mower. They are all old craftsmans that are pretty small but they all have. Peerless 400 series transmissions in them. I have taken all of the transmissions out and cleaned them and all of them are the same 401A or 400 model numbers. I just want to know if I bought something that was a good investment.
