Where can I find my lawn mower engine model number?
On the Craftsman mower model 917370680, the engine model number is typically printed on the engine itself (not on the mower deck tag). Common locations include the recoil starter housing, the sheet metal near the muffler/spark plug area, or under the engine shroud; see the 917370680 owner’s manual for model and ID label guidance.
Where to look on the engine
Check these spots first (wipe off grass and oil so you can read the stamp/label):
- On the recoil starter housing (pull-start cover)
- On the sheet metal near the muffler or spark plug
- Under the engine shroud/blower housing cover
- Near the carburetor or air filter housing area
- On a valve cover or nearby flat machined surface (some engines)
Mower model number vs. engine model number
Your mower and engine have different identifiers. This helps us match the right parts.
| What you’re identifying | Example for this unit | Where it’s found | Used for |
|---|---|---|---|
| Mower model number | 917370680 | Decal on the rear of the mower housing | Mower deck, wheels, drive system parts |
| Engine model number | Varies by engine | Label/stamp on the engine | Engine parts (carburetor, ignition, starter, etc.) |
Tips to read the tag correctly
- Look for a model, type, and code (common on Briggs & Stratton engines).
- Write the numbers down exactly as shown, including dashes.
- If the label is missing, look for a stamped number on metal surfaces.
Why it matters
The mower model 917370680 identifies the Craftsman chassis and drive components, but the engine model number is what we use to match the correct engine tune-up and repair parts.

How do I find out what kind of lawn mower I have?
For a Craftsman walk-behind mower like model 917370680, the fastest way to identify what you have is to match the mower’s model number and serial number from the deck decal, then confirm the engine model on the engine shroud. Our 917370680 owner’s manual explains where to find the mower identification decal.
Where to look on model 917370680
On this Craftsman mower, the mower model and serial number are typically on a decal on the rear of the mower housing (deck). The engine has its own model/type/code label on the engine.
- Check the rear of the mower deck for the model/serial decal
- Write down the full model number and serial number exactly as shown
- Check the engine label separately (engine model is different from mower model)
- Use the mower model to match the correct chassis parts diagrams
- Use the engine model to match the correct engine parts diagrams
Why there are “two model numbers” (mower vs. engine)
Your Craftsman 917370680 is the mower (chassis) model, but the engine is a separate Briggs & Stratton unit with its own identification. That’s normal for gas walk-behind mowers.
| What you’re identifying | What it controls | Example for this mower |
|---|---|---|
| Mower model number | Deck, wheels, handle, drive system, bagging/mulching parts | 917370680 |
| Engine model number | Carburetor, air filter, ignition, recoil starter, fuel system | Briggs & Stratton engine label |
Why it matters
Using the correct mower model and engine model prevents ordering the wrong parts, especially for common wear items like the blade, drive components, and control cables.
If you’re replacing a wear item on the mower deck, confirm it matches the mower model; for example, the correct blade for this model is the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825.

What are the common problems with Craftsman lawn mowers?
On the Craftsman 917370680 walk-behind mower, the most common problems are no-start or hard-start, loss of self-propel drive, excessive vibration, and poor or uneven cutting. These symptoms usually trace to fuel, ignition, airflow, or the blade and drive system; use the troubleshooting charts in the 917370680 owner's manual.
Common symptoms and likely causes (917370680)
- Won’t start / hard to start: stale fuel, dirty air filter, bad spark plug, spark plug wire disconnected
- Loss of power / runs rough: dirty air filter, grass buildup under the deck, fuel system varnish from old gas
- Excessive vibration: bent or loose blade, damaged blade adapter, loose blade bolt
- Uneven cut: dull blade, wheels set at different heights, deck packed with wet clippings
- Self-propel won’t move or slips: worn drive belt, drive cable out of adjustment, debris in drive wheels
Model-specific parts to check first
If your symptom points to a worn cutting or drive component on model 917370680, these parts are commonly involved:
| Symptom | Part to inspect first | What it does on this mower |
|---|---|---|
| Vibration or poor cut | Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 | The 22-inch cutting blade; damage or dull edges can cause vibration and ragged cutting |
| Blade wobble or won’t stay tight | Blade adapter 581473301 | Centers the blade and also serves as the blade adapter/pulley interface used to transfer rotation |
| Side discharge not directing clippings | Lawn mower clipping deflector 532426129 | Helps route clippings safely during side discharge |
Quick checks we recommend before buying parts
- Use fresh unleaded gasoline (do not mix oil in the gas)
- Check the oil level before each use; change oil about every 25 hours/season
- Clean packed grass from the underside of the deck (disconnect the spark plug wire first)
- Confirm all wheels are set to the same cutting height
- Inspect the blade and adapter for cracks, bends, or looseness
Why it matters
Fixing the root cause early helps prevent bigger damage, such as crankshaft issues from running a bent blade or premature drive wear from debris buildup and misadjusted controls.
