How do I identify my Craftsman lawn mower?
To identify your Craftsman riding mower, match the model number on the product identification label to your paperwork and parts listings. For this model, the correct model number is 917288120 (also shown as 917.28812 in the manual). Use the 917288120 owner's manual to confirm label location and key specs.
Where to find the model number on the tractor
On Craftsman riding mowers like model 917288120, the model and serial information is typically on a product identification label located under the seat area.
- Park on a flat surface, set the parking brake, and shut the engine off
- Flip the seat forward and look on the underside of the seat or the seat pan area
- Wipe dirt and grass off the label so all digits are readable
- Record the full model number and the serial number (both help with parts matching)
- Use the recorded model number when ordering belts, blades, pulleys, and electrical parts
What numbers to use when ordering parts
Use the model number to pull the correct diagrams and parts list; then use the part ID for the exact replacement.
| What you have | Example for this tractor | What it’s used for |
|---|---|---|
| Model number | 917288120 | Finds the correct parts breakdown |
| Manual model format | 917.28812 | Confirms operating and service info |
| Part ID | 582042802 | Orders a specific part (example: solenoid) |
If you are troubleshooting a no-start condition while identifying parts, the lawn tractor starter solenoid 582042802 is one common electrical item tied to starting.
Why it matters
A single digit off can route you to the wrong deck size, belt length, or blade style. Correct identification helps ensure the right fit for common wear items like drive belts, deck blades, and mandrel components.

How to look up Craftsman model number?
On the Craftsman lawn tractor model 917288120, you can look up the model number by finding the model and serial tag on the tractor itself, then using that exact number when searching parts and manuals. The tag is typically on the frame under the seat or on the underside of the seat; confirm the exact location in the 917288120 owner's manual.
Where to find the model and serial tag
Check these common locations first:
- On the frame directly under the seat (lift the seat to view)
- On the underside of the seat pan
- Near the rear fender area close to the seat mounting points
- On the frame rail near the battery tray (some builds)
How to read the number correctly
Use the full model number exactly as printed.
- Write it down or take a clear photo
- Include all digits (example format: 917.28812 may appear with a dot in the manual)
- Do not use the engine model number in place of the tractor model number
- Use the serial number when ordering decals, wiring, or chassis-specific items
Quick lookup checklist
Use this checklist to avoid the most common mistakes:
- Tractor model number matches the tag (not the mower deck sticker)
- Serial number is captured (helps match production run)
- Product type is correct (front-engine lawn tractor)
- You are searching parts under Craftsman 917288120
Model number vs. serial number (what each is for)
| Item | What it identifies | When you need it |
|---|---|---|
| Model number | The tractor design and parts family | Parts diagrams, belts, blades, electrical parts |
| Serial number | The specific unit and build range | Verifying correct variations and decals |
Why it matters
Using the exact model number for your Craftsman tractor prevents ordering the wrong belt, blade, or electrical component. Even similar-looking tractors can use different deck, transmission, or wiring configurations.

How to read a Craftsman serial number?
On a Craftsman lawn tractor like model 917288120, the serial number format depends on the manufacturing source, so we read it by first locating the serial tag and then matching the number pattern to the date-code style shown in the 917288120 owner's manual. This gives you the most accurate build date and parts match.
Where to find the serial number on a Craftsman tractor
Most Craftsman riding mowers and lawn tractors place the serial/model tag in one of these spots:
- Under the seat on the seat pan or fender pan
- On the frame rail near the engine compartment
- Near the rear hitch plate or transaxle area
- Under the hood near the dash tower
- On the mower deck shell (less common for the main tractor serial)
How to decode the serial number (common Craftsman patterns)
Craftsman serial numbers are not one universal format. These are the most common ways we see them decoded:
- MMDDYY (month, day, year): Example:
072811= July 28, 2011 - YYWW (year, week): Example:
2315= 15th week of 2023 - Vendor code + date code: Letters/numbers at the start identify the manufacturer; the date is embedded later
Quick check table
| What you see in the serial | Most likely meaning | What to do next |
|---|---|---|
| 6 straight digits | Often MMDDYY | Confirm against the tag layout and manual notes |
| 4 digits that look like a week code | Often YYWW | Convert week to an approximate month |
| Letters mixed with numbers | Vendor/date embedded | Use the model tag info and manual guidance |
Why it matters
The build date and serial format affect parts lookups (especially for deck components, belts, and electrical items). Using the correct serial decoding helps ensure you order the right items for your exact configuration, such as a lawn tractor starter solenoid 582042802 when diagnosing a no-crank condition.
