After reading John Smith's ID page concerning the NAA serial number location and looking at the changes in the model tractors and years. The serial number of mine is 40933, which would make it a 1940. On the intake engine side it has the 45 manifold and generator. Also the radius rods are 45 tube style, not the I style. The radiator has no shroud. What year is it really, or is it a combination of different tractors. Thanks for your help, Richard

John: I did just tonight sign up for photobucket and will try and post pics of the tractor. Thanks, Richard

A very comon practice of dealers was to have a rebuilt engine ready to go. When a farmer couldn't afford to lose his tractor because he needed to plow or plant or whatever, it really speeded things up to just do an engine swap. Most likely, you have a later production 2N with an earlier engine that was swapped into the tractor.

Relax, it happens all the time. The tractor won't run one bit differently. It's part of the charm of these old beasts.

Also be sure of your serial number - that the first or last digits haven't faded out. It should say *9N40933* Look for the *'s to deliniate the beginning and end of the serial number. Some serial numbers are so faint thet the FBI crme lab couldn't raise them.

Bob: I was searching in the archives for answers also and came to the same conclusion. The id's on the components don't make much sense. Starter bump has j207, axle trumpets: B43 left and B53 right, shift cover: S2-A, rear center section: HF TO-4024, transmission aluminum bottom cover: 9N 605-A2. The dash is cast iron or steel and not aluminum. The generator has a cut out on it but no top adjuster. Also the intake is 45 style. Maybe it's a 44 or 45 with a 40 engine. Yes it has stars on both ends of the serial number on the engine. Thanks guys for the help. Richard

1941 was a unique year for the dash. It was a one piece steel/iron casting with the steering column. In 1942 they redesigned the dash so that the dash itself is a piece of thick stamped metal and it is separate from the steering column and bolted to it. This 2N dash remained unchanged to the end of 2N production in 1947.

Hope this helps.

I think you're mixing apples and oranges a bit. Let's back up and start from the beginning.

First, what does your tractor look like?

Compare to the photos below (borrowed from John Smith's site):

Here is Tyler's very nicely restored 9N. A 2N will look very similar.

Very often a 9N or 2N will be painted red and gray like an 8N. Compare the rear wheels to quickly tell a 9N/2N from an 8N when the paint looks the same.

Here is an 8N:

Now if your tractor looks like the top photo, then your s/n would indeed be a 1940. But if your tractor looks like the second photo, your s/n would be a 1948. The serial number sequence started over when the model changed from 2N to 8N.

The s/n sequence started over again in 1953 when the NAA/Golden Jubilee replaced the 8N. If your serial number starts with NAA then your tractor should look something like this:

If it does, then your serial number says it is a 1953.

I hope this helps.

Thanks Jim: I was looking at John Smith's ID site. Mine is not a 8N as the rear wheels have the big bolt pattern and the transmission is a 3 speed. There is gray paint under the weathered red on the governor. The thing for me to do next is find the casting numbers representing dates of build.
