Tractor?

Nonetheless, parts are available and all interchange from all kinds of parts OEM, NOS, salvaged, and you name it. And depending on what you want to do...make it work, show it, rebuild it back to original, or paint it like a zebra or camouflage or worse yet green and yellow. All depends on what you want to do. But not to worry getting parts is not all that difficult.

My '40 9n has no casting codes anywhere.

John Smith has some very good information for indentifying your N series tractor with photos of items to locate. I've given the link below.

On that page is a picture of a 1939 9N. Your serial number is you best bet, but if your tractor has been rebuilt, you may have a different year engine mated with a different year rear end.

Good luck.

Second, the factory identifier for model year is the engine serial number. It will be faintly hand stamped on a boss below the head between the oil filter housing and the starter. Frequently very hard to read. 1939 first serial is 9N1;
40 first number would be 9N 10234. 41 would start with 9N 45976.

There is also a code stamped above the starter which should give you an engine build date. First letter is a month code A=January etc. then day of the month then one digit for year.

Here is the hang up==on a sixty year old tractor the engine could have been replaced. On the other hand very few 9N parts are year specific.

More than you wanted to know==right?

Your mileage may vary

Hope this helps. :})
