How to find Craftsman parts?
For your Craftsman front-engine lawn tractor model 917258904, the fastest way to find the right replacement part is to match your model number to the correct parts diagram section, then confirm the part name and ID before ordering (especially for steering, deck, and electrical items like the PTO switch).
Step-by-step: how we recommend finding the right part
- Confirm the full model number on the tractor’s ID tag: 917258904
- Identify the system you’re repairing (mower deck, steering, ignition, fuel)
- Use the parts diagram to locate the exact callout number for that system
- Match the callout to the part listing and verify the part name and part ID
- Compare your old part to the listing (mounting holes, connector style, length, and finish)
- Order the exact match; avoid “close enough” substitutions on belts, pulleys, and switches
Common parts customers look up on model 917258904
These are examples of model-matched parts that are often searched when troubleshooting starting, cutting, or steering issues:
| What you’re fixing | Part to check first | What it affects |
|---|---|---|
| Blades will not engage | Switch.pto.3 582107601 | Sends power to the electric PTO clutch circuit |
| No crank or intermittent start | Lawn tractor ignition switch 532140301 | Key-start power to starter circuit and safety interlocks |
| Poor cut or squeal under deck | Lawn tractor idler pulley 532139245 | Belt tension and blade drive routing |
| Loose steering or wandering | Drag link 532175572 | Front wheel steering linkage alignment |
Why it matters
Riding mower parts are highly model-specific. On Craftsman 917258904, small differences in a belt length, pulley offset, or switch connector can cause repeat failures, no-start conditions, or unsafe operation. Matching by model and diagram prevents wrong-part returns and downtime.

How to look up Craftsman model number?
For a Craftsman riding mower like model 917258904, you can look up the model number by finding the model and serial tag on the tractor, then using that exact number when searching parts and diagrams. On most Craftsman tractors, the tag is on the frame under the seat or on the underside of the seat.
Where to find the model number on a Craftsman tractor
Check these common locations first (clean off grass and dirt so the tag is readable):
- On the frame directly under the seat
- On the underside of the seat pan
- Near the rear fender area by the seat mounting points
- On a sticker or metal plate with both model and serial information
How to use the model number once you find it
Use the model number exactly as shown (including all digits) to match the correct Craftsman parts list.
- Enter the full model number (example: 917258904)
- Use the parts diagrams to identify the exact part name and ID
- Match by fit, not just by appearance (many parts look similar)
- If a part is missing hardware, replace the fastener with the correct type and size
Quick check: model number vs. serial number
| What you see on the tag | What it’s used for | Example |
|---|---|---|
| Model number | Finding the correct parts diagrams and part IDs | 917258904 |
| Serial number | Identifying production run details | Varies |
Why it matters
Craftsman tractors often have multiple versions that look alike but use different steering, deck, and electrical parts. Using the exact model number helps you avoid ordering the wrong items, such as a lawn tractor ignition switch 532140301 or a switch.pto.3 582107601.

What year is a Craftsman 917258904 riding mower?
A Craftsman riding mower with model number 917258904 does not have a single “model year” like a car; the exact build date is tied to the serial number and product ID tag on the tractor. We use that tag information to match the correct parts and specifications for your specific unit.
Where to find the date information on model 917258904
Look for the product identification label in one of these common locations on Craftsman front-engine lawn tractors:
- Under the seat pan (lift the seat and look on the frame or fender pan)
- On the rear frame plate behind the seat
- Near the engine compartment on the frame rail
- Under the hood on the chassis
- On the left or right side of the frame near the footrest
What to write down (so you can pinpoint the year)
The label typically includes multiple identifiers. Record all of these:
- Model number: 917258904
- Serial number: (unique to your tractor)
- Product number or ID: (sometimes shown as a separate number)
- Engine model/type/code: (useful when ordering engine-related parts)
Quick check: “model year” vs. “parts year”
For repairs, the most important thing is matching the correct parts to your exact build configuration.
| What you have | What it tells you | Why it matters |
|---|---|---|
| Model number (917258904) | Tractor family/configuration | Gets you to the right parts diagrams |
| Serial number | Build sequence and date range | Helps narrow the production timeframe |
| Engine code | Engine build date | Confirms tune-up and fuel system parts |
Why it matters
Craftsman tractors can keep the same model number while using different suppliers or running changes (switches, pulleys, steering parts). Using the ID tag details helps prevent ordering the wrong ignition switch, PTO switch, or drive components.
