How to look up Craftsman model number?
For a Craftsman riding lawn tractor like model 917288123, the model number is typically on a product ID label under the seat or on the frame near the rear wheels. Once you find it, use that exact number to match the correct parts list and diagrams in our owner's manual.
Check these common label locations first:
- Under the seat (lift the seat and look on the fender pan or seat deck area)
- On the frame rail (left or right side, near the rear wheel)
- Near the engine compartment on the frame (behind the front axle area)
- Under the hood area on a frame crossmember
- Near the footrest area on the frame
Record the information exactly as it appears on the label.
- Model number (example format: 917.XXXXXX or 917XXXXXX)
- Product number or serial number (if listed)
- Engine model and type (helpful for tune-up and starting parts)
Use this table to avoid common mix-ups when ordering parts.
| What you see on the label | What it means | Why it matters |
|---|---|---|
| Model number | Identifies the tractor platform | Ensures the right diagrams and parts fit |
| Serial number | Identifies your specific unit | Helps confirm production version |
| Engine numbers | Identifies the engine | Helps match ignition and starting components |
Craftsman tractors often share similar decals and deck sizes, but belts, blades, electrical parts, and deck hardware can vary by model series. Using the exact model number helps you get the correct items the first time, such as a lawn tractor ignition switch 532193350 or lawn tractor starter solenoid 582042802.

What kind of oil does my Craftsman lawn tractor take?
For your Craftsman lawn tractor model 917288123, use SAE 30 engine oil when operating above 32°F, and SAE 5W30 when operating below 32°F. Use a high-quality detergent oil that meets API service classification SG-SL; see the owner's manual for the full viscosity chart and maintenance details.
Use the oil grade that matches your typical mowing temperature range.
| Operating temperature | Recommended oil type | Notes |
|---|---|---|
| Above 32°F | SAE 30 | Best for warm-weather mowing |
| Below 32°F | SAE 5W30 | Helps cold starting; check level more often |
Oil capacity:
- With filter: 56 oz
- Without filter: 48 oz
Good oil habits prevent hard starting, smoking, and premature engine wear.
- Check the oil level before starting and after every 8 hours of operation.
- Change oil every 50 hours of operation or at least once a year.
- Change oil when the engine is warm (it drains more completely).
- Keep dirt out of the crankcase when removing the dipstick or drain cap.
- Tighten the oil fill cap/dipstick securely after each check.
Using the correct SAE viscosity for the temperature keeps the engine properly lubricated. Multi-viscosity oils (like 5W30) improve cold starts, but in warmer conditions they can increase oil consumption, so checking the level regularly helps protect the engine.
