How old is my mower by serial number?
For Craftsman walk-behind mower model 917375622, the serial number tells you the mower’s build identity, but the most reliable way to document “how old” it is starts with locating the serial decal and pairing it with your purchase date. We show where to find the decal in the 917375622 owner's manual.
The model and serial numbers are printed on a decal 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 is readable
- Record the serial number exactly as shown (letters and numbers)
- Record the date of purchase if you still have it
- Take a clear photo of the decal for future parts lookups
Many outdoor power equipment serial numbers include a date code (often year and week, or year and month) embedded in the first several characters. Once you have the full serial number:
- Look for a 2-digit or 4-digit year pattern (for example, “YY” or “YYYY”)
- Check for a month or week indicator near the year digits
- Compare the decoded build date to your purchase date (purchase is often later)
- If the serial format is unclear, use the parts list in the manual to confirm you are decoding the correct mower family
| Date type | What it means | Best use |
|---|---|---|
| Build/manufacture date | When the mower was produced | Estimating true age of components |
| Purchase date | When you bought it | Warranty and maintenance history |
Knowing the approximate build date helps us match the correct Craftsman parts (blade, drive belt, control cable) and avoid ordering look-alike hardware that does not fit your exact production run.
If you are also tracking maintenance by age, the manual lists key service specs such as oil capacity and blade bolt torque; keep those with your serial number record in the 917375622 owner's manual.

How to find Craftsman model number?
On the Craftsman walk-behind mower model 917375622, the model number is printed on the mower’s identification label; it’s typically found on the rear of the mower deck near the lower handle mounting area. Confirm the full model number before ordering parts or using diagrams in the 917375622 owner's manual.
Check these common label locations on walk-behind mowers like model 917375622:
- Back of the mower deck (rear-facing side)
- Between or near the lower handle mounts
- On the deck housing close to the discharge area (less common)
- On a sticker or metal tag attached to the deck
Record the model number exactly as shown, including any punctuation on the label.
| What you see | What it’s used for | Why it matters |
|---|---|---|
| Model number (example: 917.375622) | Parts lookup and diagrams | Ensures the blade, belt, wheels, and cables match your exact build |
| Serial number | Production run identification | Helps confirm compatible revisions when parts changed mid-run |
If the label is dirty or faded, these steps usually help:
- Brush off dry grass and debris first
- Wipe with a damp rag and mild soap
- Use a flashlight at a low angle to highlight embossed print
- Take a close-up photo and zoom in
Craftsman walk-behind mowers can look similar across multiple model numbers, but parts like the drive belt, drive control cable, and mulching blade can differ. Using the correct model number prevents ordering the wrong replacement part.
