What model number is the Craftsman 917377543?
The model number is 917.377543 (often written without the dot as 917377543). On this Craftsman rotary lawn mower, the model and serial number are printed on a decal attached to the rear of the mower housing; confirm it there and match it to the 917377543 parts list in the 917377543 owner's manual.
Where to find the model number on the mower
We use the model number to match the correct blade, drive parts, and hardware for your exact Craftsman walk-behind mower.
- Look for a decal on the rear of the lawn mower housing
- Record both the model number and serial number
- Write down the date of purchase if you still have it
- Use the model number when ordering parts like a blade adapter, wheel, or drive cover
Model number formats you may see
Both formats refer to the same mower.
| Format | Example | What it means |
|---|---|---|
| With dot | 917.377543 | Common on manuals and decals |
| Without dot | 917377543 | Common on parts sites and searches |
Why it matters for parts and repairs
Using the exact model number prevents ordering the wrong cutting or drive components. For example, this model uses specific items such as the lawn mower mulching blade 532406713 and the drive cover 583720801, which are not universal across Craftsman mowers.
Quick tip when the decal is hard to read
- Clean the decal gently with a damp cloth
- Take a close-up photo and zoom in
- Compare the characters to the model number shown in the manual

Where can I find my lawn mower engine model number?
On the Craftsman rotary lawn mower model 917377543, the mower’s model and serial numbers are on a decal attached to the rear of the lawn mower housing. The engine model number is typically on an engine label or stamped into the engine shroud; use the 917377543 owner's manual to confirm the exact label location and what to record.
Where to look on the mower and engine
- Check the rear of the mower deck/housing for the mower model and serial decal.
- Look on the engine shroud (blower housing) for an engine ID label.
- Check near the recoil starter/pull cord area for a sticker or stamped numbers.
- Look around the muffler side and spark plug side of the engine shroud.
- Wipe off grass and oil film; labels can be hard to read when dirty.
What numbers to write down
For parts lookup and service, we recommend recording these items:
| Item | What it’s used for | Where it’s found |
|---|---|---|
| Mower model number (917377543) | Finding mower parts diagrams | Rear housing decal |
| Mower serial number | Identifying production run | Rear housing decal |
| Engine model/type/code | Engine-specific parts and tune-up specs | Engine shroud label/stamp |
Why it matters
The mower model number (917377543) gets you the correct Craftsman walk-behind mower parts list (blade, belt, wheels, controls). The engine model number narrows it down further for engine-only items like spark plug, air filter, and carburetor parts.
Quick safety reminder before inspecting
- Disconnect the spark plug wire before reaching near the blade or working around the engine.
- Tip the mower only as directed in the manual to avoid fuel or oil spills.

Where can I find the Craftsman mower serial number?
On the Craftsman rotary lawn mower model 917377543, the serial number is on the product ID decal attached to the rear of the mower housing (deck). We recommend writing down both the model and serial number before ordering parts or looking up specifications in the 917377543 owner's manual.
Where to look on the mower
Check these spots in this order:
- Rear of the mower deck (housing): look for a decal/label with model and serial information
- Near the discharge area on the deck: labels are often placed where they stay visible
- Handle area and rear door area: some decals are easier to see with the bagger removed
- If the label is dirty: wipe it with a damp rag so the numbers are readable
What the label typically includes
The decal usually lists the key details you need for parts lookup and service.
| Item on decal | What it’s used for |
|---|---|
| Model number (917377543) | Ensures diagrams and parts lists match your exact mower |
| Serial number | Helps identify production run details and correct part variations |
| Date of purchase (your record) | Useful for maintenance tracking and service history |
Why it matters
The serial number helps us match the correct Craftsman walk-behind mower parts (like a blade adapter, belt, or control cable) to your exact build. That reduces wrong-part returns and speeds up repairs.
Quick tip for parts ordering
If you’re replacing common wear items, confirm the part location and fasteners in the manual first. For example, blade service often involves the blade hardware; having the correct fastener on hand (such as a lock nut 532409149) can keep the job from stalling.
