Ever wondered how old that trusty Craftsman lawn mower in your garage actually is? Knowing the year of manufacture can be crucial for finding the right replacement parts, estimating its value, or simply satisfying your curiosity. While Craftsman doesn't always make it easy to pinpoint the exact year, the serial number holds the key. This guide will walk you through the process of decoding that serial number and uncovering your mower's age, even if the model number is missing or incomplete.
Why Knowing Your Craftsman Mower's Age Matters
Beyond pure curiosity, knowing the age of your Craftsman lawn mower is practical for several reasons:
- Finding the Right Parts: Over the years, Craftsman has released countless models, and even similar-looking mowers can have different parts. Knowing the year of manufacture ensures you order the correct belts, blades, spark plugs, and other components. Using the wrong parts can lead to poor performance or even damage your mower.
- Estimating its Value: If you're planning to sell your mower, knowing its age helps determine a fair price. Older mowers, naturally, will be worth less than newer models, even if they're in good working condition.
- Understanding its History: Perhaps you inherited the mower from a family member or bought it used. Knowing its age provides a piece of its history and can help you understand its features and capabilities.
- Maintenance and Repairs: The age of your mower can influence the types of maintenance it needs. Older mowers may require more frequent servicing or be more prone to certain types of repairs.
- Safety: Understanding the age of your mower helps you determine if it meets current safety standards. Newer mowers may have safety features that older models lack.
Where to Find the Model and Serial Number
Before you can decode anything, you need to locate the model and serial number on your Craftsman lawn mower. Here's where to look:
- Riding Mowers: Typically, you'll find a sticker or plate located under the seat, on the frame near the engine, or on the back of the mower.
- Walk-Behind Mowers: Look for a sticker or plate on the deck of the mower, near the engine, or on the handle. It is often located on the rear deflector shield.
The model number usually starts with "917." followed by a series of numbers and sometimes letters. The serial number is usually a longer string of numbers and letters, and it's the key to determining the year. Take a picture of the model and serial number plate or sticker before you start. This will be helpful if the numbers are faded or difficult to read.
Decoding the Serial Number: The General Approach
While there's no single, universal decoding method for all Craftsman lawn mower serial numbers, here's a general approach that works for many models:
Identify the Manufacturer: Craftsman lawn mowers were manufactured by different companies over the years, primarily MTD (Modern Tool and Die Company), AYP (American Yard Products, now part of Husqvarna), and others. Knowing the manufacturer can help narrow down the decoding method.
Look for a Date Code: Some serial numbers include a date code directly within the string. This is often in the format of MMDDYY (Month, Day, Year) or YYMMDD (Year, Month, Day). Look for a sequence of numbers that could represent a date.
Check the Beginning of the Serial Number: Many serial numbers use the first few digits or letters to indicate the year of manufacture. For example, a serial number starting with "10" might indicate a 2010 model, but this isn't always the case.
Consult Online Resources: Several online forums and websites specialize in decoding Craftsman serial numbers. Search for "[Craftsman lawn mower serial number decoder]" or "[Craftsman model number lookup]" to find these resources. Be sure to provide the full model number and serial number when using these tools.
Contact Sears/Craftsman Customer Support: If all else fails, you can contact Sears or Craftsman customer support directly. Provide them with the model and serial number, and they should be able to tell you the year of manufacture.
Decoding Serial Numbers Based on Manufacturer
As mentioned earlier, different manufacturers used different serial number formats. Here's a breakdown of how to decode serial numbers based on the most common Craftsman lawn mower manufacturers:
MTD-Manufactured Craftsman Mowers
MTD (Modern Tool and Die Company) was a major manufacturer of Craftsman lawn mowers. Their serial numbers often follow a format where the first few digits indicate the year of manufacture.
- Example: If the serial number starts with "10" or "2010," it's likely a 2010 model. However, this is not a guaranteed method, and you should cross-reference with other information if possible.
Key Characteristics of MTD Serial Numbers:
- Often longer serial numbers (11+ characters).
- Usually contain a mix of numbers and letters.
- The first few characters may indicate the manufacturing plant location and date.
How to Decode an MTD Serial Number (Example):
Let's say your serial number is "115C205A678."
- Identify the Potential Year: The "115" might be a Julian date code (day of the year). The "C" is a manufacturing code. The "20" could indicate 2020, but it's unlikely considering the other numbers.
- Use an Online Decoder: The best approach with MTD serial numbers is to use an online Craftsman model number lookup tool. Enter the full serial number and model number to get the most accurate results.
AYP/Husqvarna-Manufactured Craftsman Mowers
AYP (American Yard Products, now part of Husqvarna) also manufactured many Craftsman lawn mowers. Their serial numbers often have a different format than MTD's.
- Key Characteristics of AYP Serial Numbers:
- Typically shorter than MTD serial numbers (9-11 characters).
- Often start with a series of numbers followed by letters.
- May contain a date code in the format of YYMMDD or MMDDYY.
How to Decode an AYP Serial Number (Example):
Let's say your serial number is "020304A001."
Identify the Potential Date Code: The "020304" could represent a date. It could be either:
- YYMMDD: 2002, March 04
- MMDDYY: February 03, 2004
Cross-Reference with Model Number: To determine which date format is correct, compare the features of your mower with those of models produced in 2002 and 2004. Look for product manuals online to compare.
Use an Online Decoder: If you're still unsure, use an online Craftsman model number lookup tool. Enter the full serial number and model number to get the most accurate results.
Other Manufacturers
Craftsman has also used other manufacturers over the years. If you suspect your mower was made by a different company, try searching online for "[Manufacturer Name] serial number decoder" to find specific decoding instructions.
Tips for Accurate Decoding
- Double-Check the Numbers: Make sure you're reading the numbers and letters correctly. Faded or damaged stickers can be difficult to decipher.
- Enter the Full Serial Number: Don't leave out any digits or letters. Even a single incorrect character can lead to inaccurate results.
- Consider the Model Number: The model number can provide additional clues about the year of manufacture. Use it in conjunction with the serial number when searching online.
- Look for Other Clues: Check for any other markings or labels on the mower that might indicate the year of manufacture. For example, some mowers have a date code stamped on the engine.
- Don't Rely on a Single Source: Cross-reference information from multiple sources to ensure accuracy.
What If the Serial Number is Missing or Unreadable?
Sometimes, the serial number sticker or plate is missing or damaged beyond recognition. In this case, you can try the following:
- Check the Engine: The engine may have its own serial number, which could provide clues about the year of manufacture. Look for a sticker or plate on the engine block.
- Compare with Online Images: Search online for images of similar Craftsman lawn mowers. Compare the features of your mower with those of models produced in different years.
- Consult a Small Engine Repair Shop: A knowledgeable small engine repair shop may be able to identify the year of manufacture based on the mower's design and components.
- Estimate Based on Features: If all else fails, you can estimate the age of your mower based on its features. For example, electric start mowers are generally newer than pull-start models.
Frequently Asked Questions
