Where to find model number on Craftsman lawn mower?
On the Craftsman walk-behind mower model 917387680, the model and serial numbers are printed on a decal on the rear of the lawn mower housing. Use that decal information when ordering parts or checking specifications in the 917387680 owner's manual.
Where to look on the mower
Check these common spots first (in order):
- Rear of the mower deck (rear of the housing), on a decal
- Back edge of the deck near the discharge area
- Near the handle mounting area on the deck (if the decal was relocated)
- If the decal is dirty: wipe it clean and look for “Model No.” and “Serial No.”
What the label typically shows
The decal usually includes both identifiers; record both for future reference.
| Item on decal | What it’s used for | Example format |
|---|---|---|
| Model number | Identifies the exact mower version for parts diagrams | 917.387680 (often shown with a dot) |
| Serial number | Identifies the production unit for service records | Letters and numbers |
Why it matters
Using the correct model number helps us match the right Craftsman walk-behind mower parts (blade, wheels, handle hardware, and control cable) to your exact deck and engine setup, which prevents ordering the wrong replacement.
Quick tip if you’re ordering a blade
If you’re replacing the cutting blade, match the part to your model and deck size; for this mower, a common replacement is the lawn mower blade 532406713.

What kind of gas do I put in my push lawn mower?
For the Craftsman 917387680 gas walk-behind mower, use fresh unleaded gasoline; regular pump gas is the right choice for normal mowing. Fill only at the gasoline filler cap and never add fuel indoors or near ignition sources; follow the fuel and safety details in the 917387680 owner's manual.
What we recommend for fuel
- Use fresh, clean unleaded gasoline from a busy station.
- Avoid old fuel; don’t use gas that has been sitting for more than 30 days.
- If your area offers ethanol-free gas, it helps reduce storage problems.
- If you use E10 (10% ethanol), keep it fresh and use fuel stabilizer for storage.
- Wipe up spills right away and keep gasoline off wheels and painted surfaces.
Quick fuel guidance (everyday mowing vs. storage)
| Situation | Best practice | Why |
|---|---|---|
| Weekly mowing | Fresh unleaded gas | Reliable starting and steady power |
| Hot weather mowing | Fresh unleaded gas, don’t overfill | Reduces vapor and spill risk |
| End of season storage | Add stabilizer and run the engine briefly | Helps prevent stale fuel and hard starts |
Before you fuel up (safe, fast checklist)
- Shut the engine off and let it cool.
- Move the mower to a well-ventilated area.
- Clean debris around the fuel cap so dirt doesn’t fall into the tank.
- Fill carefully; leave a little space for expansion.
- Tighten the cap securely before starting.
Why it matters
Fuel quality directly affects starting, surging, and overall engine life. Fresh unleaded gasoline helps your mower run at the correct speed under load and reduces carburetor varnish during storage.

What is the life expectancy of a gas lawn mower?
A gas walk-behind mower like the Craftsman 917387680 typically lasts 8 to 10 years with normal homeowner use and consistent maintenance. Regular tune-ups, clean operation, and proper off-season storage do the most to extend engine life and keep the deck and drive components reliable.
What most affects mower lifespan
- Maintenance frequency: oil changes, air filter service, and blade care prevent premature wear.
- Cleaning habits: built-up grass and debris make the engine run hotter and shorten engine life.
- Storage practices: storing clean and dry, plus fuel management, reduces corrosion and starting issues.
- Operating conditions: sandy soil, heavy dust, steep slopes, and thick wet grass increase wear.
- Wear items replaced on time: blades, blade adapters, spark plugs, and cables are designed to wear.
Maintenance schedule that supports an 8 to 10 year lifespan
The Craftsman manual calls out key intervals and practices that directly impact longevity. Use the 917387680 owner's manual for the exact procedures and specifications.
| Item | Typical interval | Why it matters |
|---|---|---|
| Spark plug | Each mowing season or every 100 hours | Reliable starting and efficient combustion |
| Underside deck cleaning | After each use | Prevents corrosion and airflow restriction |
| Fastener check (nuts/bolts/screws/pins) | Before storage and periodically | Prevents vibration damage and loosening |
| Blade condition | Inspect often; sharpen/replace as needed | Reduces engine load and improves cut quality |
Parts that commonly wear out first
These are normal “expendable” items on many gas mowers; replacing them on time helps the mower last longer.
- Lawn mower blade 532406713 (dull or bent blades strain the engine)
- Lawn mower blade adapter 532418373 (worn adapters can cause vibration and poor blade fit)
- Zone control cable (if the engine control bar feels loose or inconsistent)
Why it matters
Most mower “end of life” problems come from heat, corrosion, and vibration. Keeping the deck clean, the engine tuned, and the blade system tight and balanced reduces stress on the crankshaft, bearings, and mounting hardware.
