Figuring out what the John Deere serial number means not only saves you time to pick up the right model, but also gets the right parts. What’s more, it also helps you troubleshoot. This guide aims to decode both the modern and old serial numbers for you.
Modern Equipment: The 17‑Digit Product Identification Number (PIN)
Since around the year 2000, all John Deere equipment has used a 17‑digit alphanumeric Product Identification Number (PIN)—functionally similar to a car’s VIN (Vehicle Identification Number). Every digit in this code reveals something important about your tractor or mower.
Example Serial Number:
1LVZ235AHMC123456
Breakdown of the 17‑Digit Structure
| Section | Digits | Description / Example |
|---|---|---|
| World Manufacturer Identifier (WMI) | 1–3 | Identifies the manufacturer and region of production. Example: 1LV = John Deere, USA (Greeneville, TN Plant). |
| Vehicle Descriptor Section (VDS) | 4–8 | Indicates the specific model and main features. Example: Z235A = ZTrak Mower, Model Z235A. |
| Check Digit | 9 | A calculated code used internally to verify the accuracy of the PIN. |
| Year of Manufacture | 10 | Represents the production year. (See Year Code Explained below.) |
| Factory / Plant Code | 11 | Identifies the assembly plant where your equipment was built. |
| Sequential Manufacturing Number | 12–17 | The unique number for your unit in that model’s production line. |
Year Code Explained
The 10th digit in a 17‑digit John Deere PIN represents the year of manufacture. To prevent confusion, certain letters and numbers are never used (I, O, Q, Z, and 0).
| Range | Code / Year |
|---|---|
| 2001–2009 | 1–9 |
| 2010 | A |
| 2011 | B |
| 2012 | C |
| 2013 | D |
| 2014 | E |
| 2015 | F |
| 2016 | G |
| 2017 | H |
| 2018 | J (skips I) |
| 2019 | K |
| 2020 | L |
| 2021 | M |
| 2022 | N |
| 2023 | P (skips O) |
| 2024 | R (skips Q) |
| 2025 | S |
| 2026 | T |
| … | … through Y (2030) |
The sequence repeats approximately every 30 years. However, for nearly all equipment, the context of the model’s design, technology, and appearance makes it easy to identify the correct decade, preventing any confusion.
Older Equipment (Pre-2000): The 13-Digit Serial Number
If your tractor or mower was built before 2000, it likely has a 13-digit serial number. These older numbers follow a different format and do not directly encode the manufacturing year.
Example Serial Number: M00318X485001
| Position | Meaning / Example |
|---|---|
| 1 | Machine Type Code (e.g., M = Mower/Tractor) |
| 2–6 | Model (e.g., 00318 = Model 318) |
| 7 | Safety / Check Code |
| 8–13 | Sequential Production Number |
Key Difference
Unlike the modern PIN, you can’t read the production year directly from this number.
To determine the year:
- Record your full model and serial number.
- Search online or consult your John Deere dealer’s “serial number year chart.”
- Compare your serial number range to find the corresponding year of manufacture.
How to Locate Your Serial Number
Finding the identification plate is easy once you know where to look.
The black‑and‑silver metal tag is riveted to your machine’s frame and clearly labeled “Product Identification Number” or “PIN.”
Typical Locations:
- Compact Utility & Lawn Tractors: Right-hand side of the frame, below the engine, near the front wheel.
- Utility Tractors (5E–5M Series): Right-hand side of the main frame, near the steps or front axle.
- Row Crop & Large Tractors (6M–8R Series): Right-hand frame rail, often visible near the cab door or steps.
Older machines may have slightly different tags, but are usually mounted in similar areas.
Pro Tip: After finding the tag, take a clear photo with your phone. It’s your permanent backup in case the plate becomes damaged or unreadable later.
When to Use Your Serial Number
Your serial number serves multiple essential purposes:
- Order Parts: Ensures you get parts made for your exact model and build date.
- Schedule Service: Technicians use the PIN to check maintenance requirements, bulletins, or recalls.
- Register Warranty or Equipment: Registration forms and official records require the correct serial number.
Having your serial number ready allows your dealer or supplier to find everything related to your machine instantly.
Need Help Locating or Decoding Your Serial Number?
If you can’t find the tag or need help interpreting it, contact your local John Deere dealer or a trusted aftermarket parts specialist.
They can confirm your equipment’s details, decode the PIN, and help you order the correct components the first time.
Final Thoughts
Your John Deere serial number (PIN) is the foundation of your machine’s identity—revealing where it was built, when it was assembled, and what configuration it left the factory with.
