Where can I find my lawn mower engine model number?
On your Craftsman lawn tractor model 917280150, the engine model number is typically on an engine ID label or stamped into the engine metal, usually on the blower housing, valve cover area, or near the starter. Use the locations shown in the 917280150 owner's manual to confirm the exact ID points for your tractor.
Where to look on the engine (most common spots)
Check these areas with the engine cool and the key removed:
- Top and sides of the engine shroud (blower housing)
- Valve cover area (often near the top of the cylinder head)
- Near the starter motor or starter solenoid mounting area
- Along the engine block near the muffler heat shield
- Under the hood on a label near the engine (sometimes on the frame close to the engine)
How to read and record the number
Write down the full engine identification exactly as shown; it is often more than one line.
| What to record | Example format you might see | Why it matters |
|---|---|---|
| Engine model | Model code (letters and numbers) | Identifies the correct engine parts |
| Type/spec | Type or trim/spec code | Narrows down carburetor, ignition, and gasket variations |
| Code/date | Code or serial/date | Helps match production changes |
Why it matters
The tractor model number (917280150) identifies the chassis and deck parts, but the engine model number is what you use to match engine-specific items like ignition components, fuel system parts, and tune-up parts.
Related starting-system tip
If you are chasing a no-start and you hear clicking, the manual troubleshooting chart points to common causes like a weak battery, corroded terminals, wiring issues, or a faulty solenoid or starter. If you suspect the solenoid, the lawn tractor starter solenoid 582042802 is a common starting-system replacement part for this model.

What engine does Craftsman riding mower use?
For Craftsman lawn tractor model 917280150, the operator’s manual identifies it as a 17.5 HP riding lawn tractor (horsepower rated by the engine manufacturer). For the exact engine make and model used on your tractor, match the engine ID numbers on the engine to the specifications section in the 917280150 owner's manual.
How to identify the exact engine on your 917280150
We use the engine’s ID tag to confirm the correct engine family and service parts.
- Open the hood and locate the engine identification label (often on the blower housing, valve cover, or near the starter)
- Write down the model, type, and code (or similar ID fields)
- Compare those numbers to the engine information listed in the specifications section of the manual
- Use the engine ID when selecting tune-up parts (spark plug, air filter, fuel filter)
- If the tractor cranks slowly or only clicks, check battery connections and starting circuit components
What the manual tells you about this tractor (engine-related)
The manual confirms key operating details that tie directly to the engine and drivetrain.
| Item | What to expect on this model |
|---|---|
| Engine rating | 17.5 HP (manufacturer-rated) |
| Starting system | Electric start |
| Drive type | 6-speed transaxle |
| Throttle use | Best mowing performance at full speed (fast) |
Common symptoms that get mistaken for an “engine problem”
If the tractor will not crank or start, the issue is often in the starting or safety circuits, not the engine itself.
- Weak battery or corroded battery terminals
- Faulty ignition switch (a common no-crank cause) such as the lawn tractor ignition switch 532193350
- Failing starter solenoid such as the lawn tractor starter solenoid 582042802
- Safety interlock switch not made (brake pedal not fully depressed, PTO engaged, operator not seated)
- Leaving the key in a position other than STOP can discharge the battery
Why it matters
The correct engine identification ensures you buy the right maintenance parts and troubleshoot accurately. Many Craftsman tractors share similar horsepower ratings, but use different engine variants that take different filters, plugs, and adjustments.

Who makes Craftsman lawn mower engines?
Craftsman riding mowers and lawn tractors (including model 917280150) commonly use engines supplied by major small-engine manufacturers such as Briggs & Stratton, Kohler, and Kawasaki. The exact engine maker for your tractor is identified on the engine’s ID label and in the owner's manual.
How to identify the engine manufacturer on model 917280150
Use these quick checks to confirm what engine you have before ordering tune-up or starting-system parts:
- Look for the engine ID label on the blower housing, valve cover, or near the starter
- Record the engine model, type, and code/spec numbers
- Match those numbers to the engine section in the owner's manual
- If your tractor has electric start, confirm the starting circuit components (battery cables, solenoid, ignition switch)
- Use the tractor model number 917280150 when cross-checking parts diagrams and listings
What this means for parts and repairs
Even when two Craftsman tractors share the same tractor model number, the engine brand and spec can change which maintenance parts fit (air filter, spark plug, fuel filter) and which electrical parts are used for starting.
Common starting-system parts you may need
If you are troubleshooting a no-crank or click-no-start condition, these model-listed parts are often involved:
| Symptom | Common area to check | Example part on this model page |
|---|---|---|
| Single click, no crank | Starter solenoid and battery connections | Lawn tractor starter solenoid 582042802 |
| No response when turning key | Ignition switch and safety interlocks | Lawn tractor ignition switch 532193350 |
| Intermittent crank | Loose hardware and mounting points | Lock nuts and flange nuts (verify size and location) |
Why it matters
Knowing the engine manufacturer helps you get the right maintenance parts and speeds up troubleshooting. Your tractor’s manual also emphasizes safe servicing practices (for example, avoiding adjustments with the engine running and using extra caution around sharp mower blades). Refer to the owner's manual for the correct identification locations and service guidance.

What year did Craftsman make the 917280150?
Craftsman model 917280150 is part of the 917.28015 tractor series shown in the owner's manual. The exact build year is identified from the tractor’s serial number and date code on the product label (typically under the seat or on the frame), not from the model number alone.
How to find the exact year on your 917280150
Use the tractor’s product identification label to confirm the manufacturing date.
- Park on a level surface, set the parking brake, and remove the key
- Look for the product label under the seat, on the rear fender pan, or on the frame rail
- Write down the serial number and any date code printed on the label
- If the label shows a date code, record it exactly as printed (numbers and letters)
- Match the date information to the format described in the owner's manual
What “917.28015” means (and why it matters)
The manual cover lists Model No. 917.28015 for this Craftsman front-engine lawn tractor platform (17.5 HP, 38-inch mower deck, electric start, 6-speed transaxle). That identifies the series and configuration, but the serial/date code is what pins down the production year.
Why it matters
Knowing the exact year helps us match the correct parts diagrams and revisions for items like the mower deck, steering, and electrical system so you get the right replacement part the first time.
Quick reference: model number vs. serial/date code
| Identifier | What it tells you | Where to find it | Best use |
|---|---|---|---|
| Model number (917280150) | Series and configuration | Product label, manual | Finding parts lists and diagrams |
| Serial number / date code | Exact production timing | Product label on tractor | Confirming the build year |
Common parts that vary by production run
If you are ordering parts, confirming the serial/date code prevents mismatches, especially for:
- Electrical start components (for example, lawn tractor ignition switch 532193350)
- Starting circuit parts (for example, lawn tractor starter solenoid 582042802)
- Mower deck drive components (for example, lawn tractor blade drive belt 532193214)
- Deck hardware and assemblies (for example, lawn tractor mandrel housing 587819701)
