How old is my mower by serial number?
On Craftsman walk-behind mower model 917.376804, the serial number is on a decal on the rear of the mower housing; once you have that serial number, we use it to identify the manufacturing date code format and estimate the mower’s build timeframe. For the exact decal location and record fields, use the 917376804 owner's manual.
Where to find the serial number on model 917.376804
Look for a decal (label) on the rear of the lawn mower housing.
- Tip the mower only as directed in the manual (to avoid fuel or oil spills)
- Wipe the rear housing clean so the decal text is readable
- Record the serial number exactly as printed (letters and numbers)
- Record the date of purchase if you still have it
- Take a clear photo of the decal for your records
How serial numbers usually encode the build date
Many mower serial numbers include a date code near the beginning or within the string. Common patterns you may see include:
- YYMMDD (year, month, day)
- MMDDYY (month, day, year)
- YYWW (year and production week)
- A letter + numbers code where the letter indicates month or plant
Quick decode examples (common formats)
| Example code | Typical meaning | What it tells you |
|---|---|---|
| 240315 | YYMMDD | Built March 15, 2024 |
| 031524 | MMDDYY | Built March 15, 2024 |
| 2431 | YYWW | Built in week 31 of 2024 |
Why it matters
Knowing the mower’s approximate age helps us match the right Craftsman parts (blade, belt, drive components) and choose the best maintenance schedule for storage, tune-ups, and wear items.
Helpful next step
If you are already servicing the mower, follow the maintenance and storage guidance in the 917376804 owner's manual so the engine oil, blade, and drive system stay in good shape.

What model number is the Craftsman 917376804?
The model number for this Craftsman walk-behind gas lawn mower is 917.376804 (often written without the dot as 917376804). You’ll see it printed on the mower’s model label and on the cover page of the 917376804 owner's manual.
Where to find the model number on the mower
We recommend checking the mower’s model label first because it matches parts diagrams and replacement parts lists.
- Look for a model and serial number label on the mower deck (top surface near the engine) or near the rear of the deck
- Clean off grass and debris so the full number is readable
- Write the number exactly as shown, including any dots or dashes
- Record the serial number too; it helps confirm production details
- Use the model number when ordering common wear items like a blade, belt, or wheel
Why you may see the number written two ways
Both formats refer to the same Craftsman mower; the dot is a formatting style used in manuals and labels.
| How it may appear | What it means | Use it for |
|---|---|---|
| 917.376804 | Label/manual formatting | Verifying the exact mower model |
| 917376804 | Website/parts lookup formatting | Searching parts and diagrams |
Why it matters for parts and repairs
Using the exact model number helps us match the correct parts list for your 22-inch power-propelled mower, including drive system items and hardware.

- Lawn mower 22-in deck mulching blade 532406713 for cutting performance
