9N ID ?

My daughter and I picked up our first tractor to play with.
The serial number (10425) puts it as an early 1940 9N.
But it has the later dash and neutral safety start switch.
And to confuse matters even more it has 10-28 rear wheels and tires.
I read somewhere that there is a number on the rear somewhere that might
help to further ID this tractor. Where is it located?
I'll try pictures, and I know it's the wrong paint but my wife likes
the "Red Belly" tractors witch made getting permission easier.

Parts get change around on these old tractors. It's hard to find one with all original parts. The 10-28 is the old tire number, would be like 11.2 28 today. If your numbers are correct, (I would recheck them) then some stuff has been changed. As you said the dash, the hood, the fenders, the front spindles, left brake pedal, radiator, steering wheel, grill, rims.
I don't think your rear trumpet will have a production code. The tractor has most of the parts that a later 1940 would have so again check the numbers.
Will post a link to my later 1940 for comparison
Good luck with your new tractor

Here is a video of my 1940 #31798. You will note it has the same tin as yours with the hinged battery hood door, gas fill cap on the right side, single rib fenders and hump style left brake pedal. In the other video the updated one you will see the correct radiator, yours appears to be changed out. Any questions my email is open.
BTW your ferguson plow appears to be a little later '43 to '47.

There is no part number in the 10,400 range so I'm assuming you are looking in the correct spot for the serial number -see photo below. Often times folks see a number on a part and assume it is the serial number. Serial numbers on all 9N, 2N, and early 8N models began and ended with a STAR * symbol. ALL 9N and 2N's will have s/n's with the "*9N" prefix -no such thing as a '2N' stamped serial number. engine block serial numbers were marked with special steel hand stamps -see additional photo. The numeral '1' used a capital letter "I" and the numerals 6 and 9 used a lowercase letter "b". If indeed you have s/n *9N-I0425* then there are other tell-tale items to look for. Have you been to John Smiths web site? See LINK below. Do you have the original 6-volt generator or ha sit been converted to 12-volts with an alternator? I suggest you invest in the proper manuals too and read religiously. The 9N/2N Operator's and Service Manuals, an I&T F-04 Manual, and a 39-53 MPC (Master Parts Catalog) are essential required reading. I do see a smooth rear axle hub and starter button on shift cover. That was moved from the dash at s/n 12500. I see a hinged battery door, changed from the snap-in at s/n 25000, and single ribbed fenders. Tire size was measured differently back then. They were measured on the inside that is why size is marked 10-28. Later, the industry changed to measuring on the outside, thus 10-28 became 11.2 x 28 -one and the same. I can't tell for sure on yours, but the early 9N's used a 6-loop rear rim, originally 8 x 32, then the 9 x 28. This was before the hat rims were introduced. Note too that engine blocks were swapped out as well as parts. Blown or problematic engines were often swapped into other tractors so many 'mutts' are out there. Serial numbers only ID the engine block, not necessarily the entire tractor. That's why you have to look at many other parts to correctly identify it. Unless it is an early 9N and you plan to restore it to all original, what matters is that the electrical system is properly wired, be it original 6-volt/positive ground or if has been converted to 12-volts with an alternator. It is also important to note that you have a front mount distributor so your manuals will explain how to deal with it. Other early 9N parts would be a brass fuel sediment bulb assembly, hydraulic oil dipstick on shifter cover, and large, non-pressurized radiator. You can also search the archives here for other answers and post questions as well...So, welcome to the wonderful world of Ford N-Series Tractors.

New to Ford Tractors, one should invest these essential manuals for a 9N or 2N...

Thanks for the reply.
I was pretty sure it was a later 1940 but the tire size
confused me. Tractor data lists a 8.00-32 for the 9N and
10.00-28 for the 2N.
I missed getting the plow by a couple hours. But I did get
the back blade.
Thanks

Thanks for the reply.
The serial is *9NI0425*
I've got the old generator but the tractor has been converted to 12 volt.
It's been too cold since we got it home to work on it, hopefully
it warms up soon.
The p/o has some of the manuals but hasn't dropped them off yet.
Their busy trying to close out their Grandfathers estate, so i'm
just waiting.
Thanks

Tractor data is sometime not always right with there info. The 10x28 oversize tires and wheel set 9N-11170-B could be purchased in 1940. The PO of my tractor brought his tractor with the 10x28 on it. The authorized accessories show this on the back cover. This was included with all the original paperwork he gave me.

OK -just saying some things don't belong on an early 1940 9N, later ones, yes, but no big deal. You know you have a 12-volt system, and a front mount distributor, so those are two of the more important issues. I still would buy your old generator -email open once again. Do you have the round can cutout too? WIRING PICTOGRAMS by JMOR is a must-have document for every N-Owner as well as Bruce(VA)'s 75 Tips for N Owners. Good luck and have fun out there...
