4000 - 172 cu in - is it or isn't?

It is currently Ford blue, but under the hood I see some off-white or beige.
It has a 4-spd trans with the three spd range selector on the left side, thus 12 forward speeds.
12 volt generator system.

Any idea what I have?

If these numbers are correct, you have a 134 ci, 2000, made in 1964. Problem is that between 1962 and the beginning of 1964, there were only 37,930 made. This means they would have had to make and sell twice that many in 1964 alone. The model number is as follows:

21301
2 = 134 cu. in. gas or 144 cu. in. diesel engine
1 = Ind. and ag. models produced after 1963
3 = Utility-type tractor w/non-adj. front axle
01 = Four-speed w/o PTO

No idea what the "S" is..... .

If this is not correct, check the numbers as mentioned above. If you bought this as a 4000 with the 172 "Red Tiger", the seller was mistaken. Also, the 4000's made in 1965 were 3 cyl., not 4, and were COMPLETELY different animals.

I double checked the numbers...they are correct. The only thing to add, is there are diamonds fore and aft the 64274 s/n. It's also a gas engine.

I also found casting numbers on the right side of the block which read " CONN 6015J" and a set on the left side "7F16" ( the 6 could be a 0 ). That one looks like a casting pour date.

Are these any help?

Are there any differences in appearance between a 134 ci and a 172 ci?

Does the high serial number make sense?

Thanks for the help, Jay.
