To verify that the tractor is actually the tractor that is listed on the foil tag under the hood (hoods are easily changed)
Look on the bell housing just above andbto the rear of the starter. There will be some numbers Hand Stamped there. NOT raised cast numbers.
You will likely have to scrape some rust, paint and crud off to see them. See photo for example.
