How to look up Craftsman model number?
For a Craftsman riding tractor like model 917258872, you can look up the model number on the tractor’s model plate (typically under the seat). Use that full model number when ordering parts or checking specifications in the 917258872 owner's manual.
Where to find the model number on the tractor
On Craftsman front-engine lawn tractors, the tractor model number is on a model plate under the seat.
- Park on a flat surface, set the parking brake, and turn the key off
- Let hot engine and muffler parts cool
- Lift the seat and look for a sticker or metal plate
- Write down the full model number exactly as shown (for example, 917.258872)
- Keep it with your maintenance records for faster parts lookup
Tractor model number vs. engine model number
Your tractor and engine have different model numbers. The tractor model number is used for chassis, deck, steering, and drive parts; the engine model number is used for engine-specific parts.
| What you are identifying | Where to look | Example from this model |
|---|---|---|
| Tractor model number | Model plate under the seat | 917.258872 |
| Engine model number | Blower housing on the engine | CV20S-PS65530 |
Tips for using the model number to find the right parts
Once you have the tractor model number, match it to the parts diagram and parts list.
- Use the tractor model number for items like tires, belts, and steering parts
- Match the part description to the diagram callout before ordering
- Replace missing wheel trim with the correct axle cap style, such as the hub cap 532104757 when it matches your diagram
- If you are unsure between similar hardware (nuts, clips, washers), compare size and thread specs listed in the parts list
Why it matters
Using the exact Craftsman model number prevents ordering the wrong belt, deck component, or steering linkage. It also helps you find the correct safety and operation information for your specific tractor.
