What Is a Craftsman Lawn Mower Serial Number? (Year Lookup Guide)
A Craftsman lawn mower serial number is a unit-specific identifier printed on its product label. It may help a manufacturer confirm when the mower was built, but Craftsman has no single year code that works across all models. Record the full serial and model numbers, then verify the date through the maker’s matching records or support.
Could two Craftsman mowers that look alike have different year codes? Yes. The serial number belongs to one specific mower, and its format can depend on the mower’s model and original manufacturer. The steps below help you find the label and check the year without relying on a guess.
What a Craftsman Lawn Mower Serial Number Identifies
A serial number is the identifier assigned to an individual mower. It differs from the model number, which identifies a product design or configuration. A serial may contain production information, but you can use it to establish a build date only when the correct manufacturer’s format or records support that reading.
Think of the model number as identifying the kind of mower, and the serial number as distinguishing one unit from others of that model. For a year lookup, both numbers are useful. The model helps point you to the right manufacturer, manual, parts list, and serial-number system.
A serial number is not necessarily the mower’s model year, the year it was sold, or the age of its engine. Those dates can differ. If you need a reliable manufacture date, ask the manufacturer or an authorized support channel to interpret the mower’s complete identification details.
Find the Craftsman Model and Serial Number
The model and serial numbers are usually printed on a product identification label attached to the mower. Label locations vary by mower type and model. Check the frame, mower deck, rear body, and seat area; on a riding mower, also look beneath or behind the seat and consult the operator’s manual.
Before searching, park the mower on level ground, switch it off, and remove the ignition key if it has one. Let hot parts cool. If you need to reach beneath the deck, disconnect the spark-plug lead first. For battery-powered equipment, follow the manual’s battery-isolation instructions.
Look for a label or plate that lists both the model and serial number. If grass or dirt hides the information, clean the label gently with a cloth. Do not scrape it or use a solvent that could damage the printed details.
Write down each number exactly as shown. Keep letters, leading zeros, and separators. Take a clear photo of the full label, including any brand or manufacturer information. A partial or misread number can lead to a wrong date estimate or an incompatible part.
If the label is hard to read, use good lighting and take close-up photos from different angles. Do not guess at unclear characters. A support representative may be able to help interpret a photo, but the result still depends on having enough legible information.
Identify the Manufacturer and Verify the Mower’s Year
Craftsman mowers have been made by different manufacturers, so the serial-number format is not universal. A model prefix can help identify the likely maker: 247 generally points to MTD-built equipment, while 917 generally points to equipment built by AYP/Husqvarna. Neither prefix, by itself, tells you the mower’s year.
Start with the complete model number and the mower type, such as a walk-behind mower or riding mower. Then use the matching manual, manufacturer parts lookup, or support channel. These sources can help identify the correct product family and may offer a way to confirm the production date.
| What you have | What it can tell you | What it cannot confirm alone |
|---|---|---|
Model prefix 247 |
The mower is generally associated with MTD-built equipment | The mower’s manufacture year |
Model prefix 917 |
The mower is generally associated with AYP/Husqvarna-built equipment | The mower’s manufacture year |
| Complete model number | Product configuration and the right parts information | A confirmed build date in every case |
| Complete serial number | A unit-specific identifier that may support a date lookup | A date without the right format or manufacturer records |
| Engine label or date | Information about the engine | The mower’s manufacture date |
Some online sites offer serial-number decoders. Treat a result as a lead, not proof, unless it matches the applicable manufacturer’s format and can be corroborated. If the format is unclear, ask manufacturer support to confirm the build date using the complete model and serial numbers.
Do not infer the year from the mower’s appearance, an engine date, or a partial serial. An engine may have been made before the mower was assembled, and parts may have been replaced. The mower’s own identification details are the better starting point.
Compare Common Year-Lookup Situations
A lookup scenario shows how to handle the information you have without filling in missing details by guesswork. These examples are illustrative, not confirmed histories of particular mowers. In each case, the safe next step is to match the full model and serial numbers with the correct manufacturer’s information.
| Situation | Sensible next step | Avoid |
|---|---|---|
A complete 247 model and serial are readable |
Check the matching MTD-related manual or support lookup; ask support to confirm the date | Treating 247 as a year code |
A complete 917 model and serial are readable |
Check the matching AYP/Husqvarna-related information or support channel | Assuming every 917 serial uses one year formula |
| The model is readable, but the serial is worn | Photograph the label and contact support with all remaining identifiers | Using a partial serial to decode a year |
| The label is missing or replaced | Look for other remaining identifiers and ask the manufacturer what it can verify | Ordering parts based on appearance or a guessed year |
| The engine has a readable date code | Use it only as engine information unless the mower maker confirms more | Treating the engine date as the mower’s build date |
For example, if a mower’s label clearly shows a model beginning with 247, that prefix can help direct your search to the likely manufacturer. It does not establish a production year. You still need the complete serial and a model-specific lookup or confirmation.
If a riding mower’s label is partly hidden beneath the seat, consult the operator’s manual before moving parts or reaching into a tight area. If the numbers are unreadable, stop rather than scraping the label. A clear photo and the remaining numbers are more useful than a damaged label.
Use the Correct Model Number for Parts and Service
The model number is usually the key identifier for finding parts that fit a mower’s design. The serial number can help distinguish the individual unit or narrow down production details, but it should not replace the model number when you search for parts or request service.
When looking up a part, enter the complete model number into the matching manufacturer’s parts resource. Check that the result describes the same mower type and configuration. If a parts listing asks for a serial range, provide the serial number too, and follow the listing’s instructions.
If a listing or repair guide uses a year, confirm that the year applies to your specific model. Do not choose a part because a mower looks similar or because an online year estimate seems close. When information conflicts, pause and ask the manufacturer or a parts specialist to verify compatibility from the full model and serial.
Keep the distinction simple:
- Model number: identifies the mower’s product configuration and is the main starting point for parts.
- Serial number: identifies an individual mower and may help confirm production information.
- Engine number or code: identifies engine information and does not automatically establish the mower’s year.
Preserve Identification Labels and Records
A machine record makes future year checks, parts searches, and service questions easier. Save the confirmed model and serial numbers, the manufacturer’s date confirmation if available, and the matching manual in one place. A label photo is useful, but it does not replace the written numbers.
Store the information on your phone or with the mower’s paperwork. Include the date you checked the information and where the confirmation came from. If a later parts lookup gives a different result, you can compare the records rather than starting over.
If the label is worn, damaged, or replaced, do not try to restore it by scraping, grinding, or using chemicals. Contact the manufacturer with every remaining identifier and explain what is missing. It may be able to confirm some details, but a year should not be treated as certain unless the available information supports it.
Conclusion
A Craftsman serial number identifies an individual mower, but it does not follow one year-decoding rule across all models. Find and record the complete model and serial numbers, use the model prefix only to guide your manufacturer search, and confirm the build date through matching documentation or support. Use the model number, not a guessed year, to begin a parts search.
Frequently Asked Questions
These short answers cover common questions about Craftsman mower serial numbers and year lookups. The main point is consistent: the complete model and serial numbers are more useful than a prefix or visual estimate, and manufacturer-specific information is needed to confirm a production date.
Where is the serial number on a Craftsman lawn mower?
Check the product label on the frame, deck, rear body, or seat area. On a riding mower, look beneath or behind the seat. Locations vary, so use the operator’s manual for the exact spot.
Is the Craftsman model number the same as the serial number?
No. The model number identifies the mower’s product configuration. The serial number identifies an individual unit and may help with production-date records.
Can I tell the year from a Craftsman serial number?
Sometimes, but only if the serial format for that model is known or the manufacturer can confirm it. Craftsman does not use one universal year code across all mowers.
Does a 247 prefix tell me the mower’s year?
No. 247 generally identifies MTD-built equipment, but it does not establish the manufacture year.
Does a 917 prefix tell me the mower’s year?
No. 917 generally identifies equipment built by AYP/Husqvarna, but the prefix alone does not confirm a date.
Can an engine date code tell me when the mower was made?
Not by itself. The engine and mower may have different production dates. Ask the mower’s manufacturer to confirm the mower’s build date.
What should I do if the serial-number label is unreadable?
Photograph it, record every legible character, and contact manufacturer support with the complete model number and any other remaining identifiers. Do not guess at missing characters.
Can I order parts using only the serial number?
Use the complete model number as your starting point. Provide the serial too if a parts lookup or support representative requests it, especially when production details may matter.
Is an online Craftsman serial-number decoder reliable?
It may offer a useful lead, but verify the result against the correct manufacturer’s format, documentation, or support channel before treating it as confirmed.
Should I use the mower’s appearance to estimate its year?
No. A mower’s appearance can be misleading, especially if parts have been replaced. Use the identification label and manufacturer records instead.
