The Craftsman lawn tractor model 917280151 is equipped with a 17.5 HP low-emission engine (as rated by the engine manufacturer). For the exact engine identification (model, type, and code), we use the engine ID label on the engine and confirm it against the owner's manual.
How to identify the exact engine model on 917280151
Use the engine’s ID label, then match it to the parts listing and specs.
- Turn the key off, remove it, and let the engine cool
- Lift the hood and look for an engine label or stamped tag
- Record the model, type, and code (or similar fields)
- Use those numbers to match the correct tune-up and engine parts

Where to look for the engine ID label
Most riding mower engines place the ID in one of these spots:

What year did Craftsman make the 917280151?
Craftsman model 917280151 was produced across multiple years; the model number alone does not identify a single build year. To get the exact year for your tractor, use the manufacturing date information on the product identification label and confirm the label location in the Owner's manual.
How to find the build date on model 917280151
Look for the product identification label in the most common locations for Craftsman riding tractors:
- Under the seat (seat pan area)
- On the frame rail near the seat
- Near the rear fender or hitch/drawbar area
- On the underside of the hood or near the dash (less common)
- On a vertical frame surface where it is protected from debris
How to use the label to determine the year
Once you find the label, write down everything exactly as printed (model, serial, and any date code). Many labels include a date code or a serial format that indicates when the tractor was built.
| Label detail you find | What it tells you | What to do next |
|---|---|---|
| A printed date or date code | The build year is included | Use the year shown to identify the correct parts configuration |
| Serial number only | The build date may be encoded | Use the serial format guidance in the manual and match parts by exact model and serial range |
| Label missing or unreadable | You still can narrow it down | Use engine ID numbers and the tractor’s parts configuration to match components |
Why it matters
Craftsman tractors can have running changes during production; the build year and serial range affect fit for deck, steering, and starting components. Confirming the year helps you order parts that match your exact configuration.
Parts that commonly vary by production run
After you identify the year or serial range, double-check these areas before ordering:
- Mower deck mandrel and spindle setup (example: Lawn tractor mandrel housing 587819701)
- Deck belt routing and belt length (example: Lawn tractor blade drive belt, 7/16 x 90-1/4-in 532193214)
- Key switch style and wiring connector (example: Lawn tractor ignition switch 532193350)
- Starting circuit components such as the solenoid (example: Lawn tractor starter solenoid 582042802)
