Hi,

The model serial number of a John Deere lawn mower is printed on an identification tag located on the left side of the deck (standing behind the mower). The serial number (PIN) is 13 or 17 digits long. Photos of the 1935 Model “DI” serial number 123172 currently on display at the John Deere Pavilion. This tractor is the first official industrial tractor sold to the public.

Earlier today over in the Late Model Tech forum I referred to the Serial Number Magic Decoder Pin here in the FAQs.
Only, I cannot seem to find a post where it was spelled out stand-alone. Oh, I see it in several other threads. Just not by itself. So, time to do a little cutting and pasting:
Explanation of Type Codes per SM 2064
Basic Tractor Serial Number Explanation

T 5 F 3 M xxxxxx T
1. The first letter designates the application T = Tractor
2. This number designates the series
4 = JD350 Deere

5 = JD450
3. This number designates tractor style
C = Crawler
E = Crawler Loader
F = Crawler Dozer
4. This number designates the fuel type of the engine:
1 = Gasoline
3 = Diesel
(2 must have been LP Gas)
5. This letter designates the type of transmission:

D = Directional Reverser (JD 350)
M = HLR (JD 450)
6. Sequence serial number of six digits

7. This letter designates the plant:
