How to find Craftsman model number?
On a Craftsman walk-behind mower like model 917377041, the model number is typically printed on the mower’s identification label on the rear of the deck, near the lower handle mounting area. Match that number exactly when ordering parts or using the 917377041 owner's manual.
Check these common label locations first:
- Back of the mower deck, between the lower handle mounts
- Rear deck panel just above the discharge area
- Near the height-adjuster brackets on the deck (less common)
- On a worn label, the model number may be faint; use a flashlight and wipe off dirt
For the best parts match, record the full ID information from the label.
- Model number (example: 917377041)
- Serial number (helps confirm production run)
- Engine model (this mower uses a Honda GCV160 series engine per the manual)
- Any extra suffixes or revision codes printed after the model number
| Item on label | What it’s used for | Example |
|---|---|---|
| Model number | Correct parts diagrams and assemblies | 917377041 |
| Serial number | Confirms exact build/version | Varies |
| Engine model | Engine-specific tune-up parts | Honda GCV160 |
Craftsman walk-behind mowers often share similar decks and controls across multiple models, but small differences (drive cable routing, wheel hardware, blade brake and clutch setup) can change the exact replacement part you need. Using the exact model number prevents ordering the wrong blade, drive parts, or hardware.

Should I use 87 or 91 gas for lawn mower?
For the Craftsman walk-behind mower model 917377041, we recommend using regular unleaded 87-octane (87 AKI) gasoline for normal operation. Higher octane (like 91) does not add power or improve reliability in a typical small mower engine; fresh, clean fuel matters more.
- Use fresh, clean unleaded gasoline (87 AKI).
- Avoid old fuel; stale gas is a top cause of hard starting and rough running.
- Avoid high-ethanol blends when possible; ethanol attracts moisture during storage.
- Do not mix oil into the gas unless your engine is specifically a 2-cycle design (most walk-behind mowers like this are 4-cycle).
- If the mower will sit, add fuel stabilizer and run the engine briefly to circulate treated fuel.
| Fuel choice | OK to use? | When it makes sense |
|---|---|---|
| 87 octane (regular) | Yes | Everyday mowing and best overall choice |
| 89 octane (mid-grade) | Yes | Fine if that is what you have available |
| 91+ octane (premium) | Yes | No real benefit for mowing; use only if already in your can |
| Old/stale gas | No | Drain and replace with fresh fuel |
These checks solve most “bad gas” symptoms on model 917377041:
- Drain the tank and refill with fresh gasoline.
- Check and replace the spark plug if starting is inconsistent.
- Clean or replace the air filter if the engine surges or smokes.
- Verify the fuel valve lever (if equipped) is in the ON position.
- Review the fuel and starting steps in the 917377041 owner's manual.
Using the correct fuel helps prevent hard starting, surging, and carburetor varnish. The manual’s troubleshooting guidance also points to fresh gasoline and basic tune-up items (air filter, spark plug) as key fixes when the engine will not start or runs rough.
