How old is my mower by serial number?
On Craftsman model 917376390, the serial number is on a decal on the rear of the mower housing; once you have that number, we use it to identify the manufacturing date range (the exact format varies by the engine and mower components). The fastest path is to match your serial to the identification details shown in the 917376390 owner's manual.
Where to find the serial number on this mower
The manual specifies the model and serial numbers are located on a decal on the rear of the lawn mower housing.
- Tip the mower only as recommended in the manual (avoid spilling fuel and oil)
- Wipe the rear housing clean so the decal is readable
- Write down the full serial number exactly as printed
- Record the date of purchase too; it helps confirm the age range
How to decode the age from the serial number
Serial formats are not universal, so we decode it by looking for a date code pattern and by identifying which component the serial belongs to.
- Look for a 2-digit year (YY) or 4-digit year (YYYY) embedded in the serial
- Check for a month code (MM) near the year (common patterns include YYMM, MMYY, or MMDDYY)
- If the mower deck decal does not include a clear date code, check the engine identification label (many engines use their own date coding)
- Compare the serial format to the identification section in the 917376390 owner's manual
Quick reference: common date-code patterns
| Pattern you see | What it usually means | Example interpretation |
|---|---|---|
| YYMM | Year then month | 2304 = April 2023 |
| MMYY | Month then year | 0423 = April 2023 |
| MMDDYY | Month, day, year | 040523 = April 5, 2023 |
| YYMMDD | Year, month, day | 230405 = April 5, 2023 |
Why it matters
Knowing the mower’s age helps us choose the right maintenance schedule (oil, blade, drive system checks) and prevents ordering the wrong replacement parts when designs change mid-production.

Where is Craftsman's model number?
On the Craftsman walk-behind mower model 917376390, the model number is printed on the mower’s identification label and is also shown on the cover page of the 917376390 owner's manual. For this mower, the model number is 917.376390.

Mower model number vs. engine model number
Many customers find an engine number first, but that is not the same as the mower model number.
| What you’re identifying | Where it’s found | What it’s used for |
|---|---|---|
| Mower model number (917376390) | On the mower ID label and in the manual | Ordering Craftsman mower parts like blades, wheels, and cables |
| Engine model/type/code | Stamped or labeled on the engine shroud or valve cover area | Ordering Briggs & Stratton engine parts (carburetor, ignition, etc.) |
Why it matters
Using the correct mower model number helps us match the exact parts list and diagrams for your deck, drive system, and controls. For example, this model uses a 22-inch 3-in-1 blade such as the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 when you are replacing cutting components.
