IH 666 Serial Number Qestion

E

My father owns a IH 666, and it has a rather strange serial number. Normally, I don't have a problem placing dates and such, but this is a bit of a poser. The full number on the plate is:

F2450146U010530

There are NO spacings in between the numbers and letters, and the stampings are clear and legible.
I'm assuming the numbers after the F are the serial, except there are too many: 666's should only have 5 digits, which could mean the number after the U, except IT starts with 0.

Am I making this harder than it is and reading too much into it?
Anybody able to decipher what all the numbers and letters mean?
Help?
 
If 10530 is the serial, then what are all the numbers in front? Usually IH listed the serial numbers after the F.

And that begs the question of the 'U'....this is a row crop tractor, so even if IH went with the obvious, as in utility, it still seems really odd.
 
Kind of a fine line between the Utility, row crop, and wheatland versions of the "larger" tractors during that time period. At that time the row crop was still Farmall. The 666 only came in the International version -- thus it may have been considered a "utility". It also came in a high clearance version. I have never seen one, so should not comment -- info is from the literature I have. You can cultivate with utility type tractors. "Generally" they were not used with front mount cultivators, there are exceptions, maybe the 666 is one of those.
 


The first numbers on there are build codes that designate what machine it is. These are between the F and the U

I believe the U stands for unit. 010530 is the SN.
 
I have never seen a 666 utility. All I ever seen have Farmall 666 on the model tag and International on the hood. 666 was designed for front mount cultivators same as all Farmall tractors. It is a Farmall. It is a genuine row crop tractor. Mine even has the tricycle Farmall front end.

As I stated, I haven't seen one. Also the books I have don't show the pictures, so I assumed the International only as listed in Ken Updike's book meant there was no row crop, instead of there being no utility. As your picture indicates, I was wrong as I have never learned not to assume anything. Obviously that is a row crop -- NOW (too late to weazel out of my mistake) I suddenly regained my brain function. I was thinking of a 606, of which there is not "supposed" to be a row crop version, only a Utility -- haven't seen one of those in person either, so I won't comment further. I left the farm in 1960, retired in 2001, began to collect and study International after 40+ years, I should not comment on anything newer than a 460/560. Enough baloney.
 
CNKS it doesn't matter one bit, that is why this is such a great forum. Have plenty of folks to catch mistakes. You are 100% correct about the 606 it was available as utility only as far as I know. I have seen a couple of them, and they were utility tractors.
 
The fist prtion of the serial number is kind and code for ordering and factory production information. The "U" is for country of manufacture, United States, in this case. The next six digits are the serial number. Since they never reached 100,000 units, the first "0" is just a filler to retain the six digits in this location. As best as I can remember, country codes were U=US, C=Canada, B=Britain, D=Germany (Deutchland I think),J=Japan. There were probably others nut these were the ones we saw commonly here in eastern Canada.

read Ken's book again, carefully. within a few pages of the info you are remembering, i believe he also writes that beginning with the '66 series, the Farmall name was dropped, and the series number was the only indication of row crop, utility, etc.

I am not having much luck tracking down the year of my 666. The serial number I have is 2450168U14580. Any help would be greatly appreciated.

Thanks!
