Unlocking the secrets of your vintage Farmall 656 often starts with a simple number: the serial number. This seemingly insignificant string of digits holds the key to determining the year your tractor rolled off the assembly line, and that information is crucial for everything from ordering the correct parts to understanding its historical significance. Knowing the model year allows you to properly identify components, troubleshoot issues specific to certain production runs, and even accurately assess its value. Let’s dive into how to decipher this vital piece of information and what you can learn from it.
Why Knowing Your Farmall 656's Model Year Matters
Beyond simple curiosity, pinpointing the exact year of your Farmall 656 unlocks a wealth of practical benefits. Think about it: Farmall made subtle but important changes to the 656 throughout its production run. Knowing the year helps you:
- Order the Right Parts: Parts compatibility can vary slightly from year to year. Using the serial number to determine the model year ensures you're getting the correct components for repairs and maintenance.
- Understand Specific Issues: Certain years might be known for specific problems or design flaws. Knowing your tractor's year allows you to research potential issues and be proactive in addressing them.
- Assess Value Accurately: The model year is a significant factor in determining the value of your tractor. Older or rarer years might command a higher price.
- Trace Its History: The model year is a starting point for researching the tractor's history, including its original owner, where it was sold, and its overall story.
Where to Find the Serial Number on Your Farmall 656
Before you can decode the model year, you need to locate the serial number. Fortunately, Farmall kept it in a relatively consistent location.
- Primary Location: The most common location is on a plate located on the left-hand side of the tractor, near the clutch housing. Look for a small metal plate riveted to the casting.
- Alternate Location: In some cases, the serial number might be stamped directly into the clutch housing itself, usually in the same general area. You may need to clean the area thoroughly to reveal the stamped number.
- Paperwork: Don't forget to check your paperwork! The original owner's manual or sales receipt might contain the serial number.
Important Tip: Serial number plates can be damaged, lost, or painted over. If the plate is missing or unreadable, try the alternate location or consult with a Farmall expert who might be able to help identify the tractor based on other features.
Decoding the Serial Number: Cracking the Code
Once you've found the serial number, you can use it to determine the model year. Here's a breakdown of the serial number ranges for the Farmall 656:
- 1965: 501 - 5164
- 1966: 5165 - 18430
- 1967: 18431 - 32950
- 1968: 32951 - 48850
- 1969: 48851 - 58621
- 1970: 58622 - 65470
- 1971: 65471 - 70292
- 1972: 70293 - 75000
Example: If your Farmall 656 has a serial number of 25000, it was manufactured in 1967.
Important Considerations:
- Serial Number Breaks: Note that the serial number ranges often end mid-year. This means that a tractor with a serial number close to the end of a range might have been manufactured late in that year, or even early in the following year.
- Suffix Letters: Some Farmall 656 tractors may have a suffix letter after the serial number (e.g., "R", "V", or "D"). These letters typically indicate specific engine configurations or other options. While the serial number itself determines the model year, the suffix can provide additional information about the tractor's specifications.
- Canadian Production: If your Farmall 656 was manufactured in Canada, the serial number ranges might be slightly different. Consult with a Farmall expert or a Canadian tractor registry for accurate information.
Key Features and Changes Throughout the Farmall 656 Production Run
While the serial number tells you the year, understanding the changes and features introduced during the Farmall 656's production run adds another layer of knowledge. Here are some notable changes:
- Early Models (1965-1967): These models typically featured the original design and components.
- Mid-Production Models (1968-1970): Some minor cosmetic and mechanical changes might have been introduced during these years. Check parts catalogs specific to these years for any subtle differences.
- Late Models (1971-1972): Later models might have incorporated improvements based on feedback from the field.
Important Note: Documenting the specific changes introduced each year is difficult without access to detailed factory records. Relying on parts catalogs, owner's manuals, and the expertise of Farmall enthusiasts is crucial for accurate information.
