odd serial number

1-----2345----6----- 7 SNM 43TR 010001 T

The fifth number can either be an R,U,H . Number 5 on my engine serial number is four (4)

SNM 41T4 0166xx T

Sonething is not right

The serial number is clear and easy to read and I have checked it closely several times.

Anyone have any information on these serial numbers

(1)SN-serial number
(2)M- Engine
(3)4- 3cylinder
(4)1-gasoline 3-diesel
(5)R-RU model L-LU model H-HU model
(6)sequence serial number(010001)
(7)T-Dubuque

Thanks

Not sure if you are referring to the TRACTOR serial number or the ENGINE serial number, but in either case I believe the information you are using is inaccurate.

If you are looking at the TRACTOR serial #:

The first letter designates tractor..... ..... ... T
The first number designates series..... ..... 4 (a 1020)
The next letter designates style..... ..... ..... R, H, or L
The next number designates fuel type..... 1 (gasoline) 3 (diesel)
The next letter designates trans. type..... ....C, D, H
The next six digits are the serial number
The final letter designates the manufacturer.....T (Dubuque)

I emailed John Deere maybe they have more info.

I'll let you know if they turn up anything interesting
