The Massey Ferguson 135: a tractor that's more than just a machine. It's a workhorse, a piece of history, and for many, a cherished family heirloom. Knowing the year your MF 135 was built isn't just about satisfying curiosity; it's crucial for sourcing the correct parts, understanding its value, and appreciating its place in the legacy of agricultural machinery. This guide will help you decipher the serial number on your MF 135 and unlock its history.
Why Knowing Your MF 135's Year Matters
Pinpointing the exact year of manufacture for your Massey Ferguson 135 opens a world of benefits. It's not just about bragging rights, although owning a classic like this is certainly something to be proud of.
- Parts Identification: Sourcing the right replacement parts becomes significantly easier. The MF 135 underwent minor changes throughout its production run, and parts that fit a 1965 model might not be compatible with a 1970 version. Knowing the year ensures you get the perfect fit.
- Accurate Valuation: Whether you're buying, selling, or simply insuring your tractor, the year of manufacture plays a significant role in determining its market value. Older, well-maintained models can command a premium.
- Historical Context: Understanding the year your tractor was built allows you to delve into the historical context surrounding its production. What were the economic conditions? What other innovations were happening in agriculture at the time? It adds a layer of depth to your appreciation of the machine.
- Restoration Accuracy: If you're planning a restoration project, knowing the original specifications for your tractor's year is essential for achieving historical accuracy.
Where to Find the Serial Number on Your MF 135
The serial number on your Massey Ferguson 135 is usually stamped on a plate or tag located in one of these places:
- On the dashboard: Look for a small metal plate riveted to the dashboard, usually on the right-hand side. This is the most common location.
- On the engine block: Sometimes, the serial number is stamped directly into the engine block itself. This is less common, but worth checking. Look near the starter motor or around the fuel pump area.
- On the transmission housing: Another possible location is on the transmission housing, typically on the left-hand side, near where the gear shift lever is located.
- Under the seat: In some cases, a plate may be found under the seat, affixed to the seat support structure.
Pro Tip: Years of dirt, grime, and rust can obscure the serial number. Use a wire brush and some penetrating oil to carefully clean the area before attempting to read it. A good flashlight is also invaluable.
Decoding the Serial Number: Unlocking the Year
Once you've located the serial number, you'll need to decode it to determine the year of manufacture. Massey Ferguson used a sequential numbering system, so earlier serial numbers correspond to earlier production years. Here's a general guide to help you:
Important Note: These ranges are approximate and can vary slightly depending on the manufacturing location (Coventry, UK or Detroit, USA). Use this as a guideline, but always cross-reference with other sources if possible.

- 1974: 9A90001 - 9A99999
Example: Let's say your MF 135 has a serial number of 255000. Looking at the Coventry, UK serial number ranges, this falls between 245168 and 262202, indicating that it was likely manufactured in 1969.
Important Considerations:
- Serial Number Overlap: There can be some overlap in serial number ranges between years, especially at the beginning and end of a production year.
- Rebuilt Tractors: If your tractor has been rebuilt or had major components replaced, the serial number might not accurately reflect the original year of manufacture.
- Data Plate Replacement: The original data plate containing the serial number could have been lost or replaced over the years.
- Variations: There can be slight variations in serial number formats and locations depending on the specific model and manufacturing plant.
Beyond the Serial Number: Other Clues to Age
While the serial number is the most reliable indicator of your MF 135's age, other clues can help you narrow down the timeframe:
- Engine Type: Different engines were used in the MF 135 over its production run. Researching the engine type in your tractor can provide valuable information. For example, the Perkins AD3.152 diesel engine was a common choice.
- Transmission Type: The MF 135 was available with different transmission options, including a manual transmission and a Multi-Power transmission. The presence of Multi-Power can help identify a later model.
- Sheet Metal Design: Minor changes were made to the sheet metal design over the years. Examining the shape of the hood, fenders, and grill can offer clues.
- Paint Color: While paint can be changed, knowing the original paint colors used by Massey Ferguson during different years can be helpful.
- Options and Features: The availability of certain options and features, such as power steering or specific types of hitches, can also help determine the age.
