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 parts listing; for this tractor, the model number format you need is 917258873. On most Craftsman riders, the label is under the seat, so flipping the seat forward is the fastest way to confirm the exact model.
Where to find the model number on a Craftsman rider
Check these common label locations first:
- Under the seat (often on the underside of the seat or on the frame directly beneath it)
- Rear fender pan area near the seat mounting points
- Frame rail near the engine compartment
- Under the hood near the dash tower (less common)
- Near the transaxle area on the frame (occasionally)
What to write down (so you get the right parts)
Record the information exactly as printed on the label:
- Model number (example: 917258873)
- Product number (if shown)
- Serial number
- Engine model and type (helpful for tune-up and fuel system parts)
Quick check table
| Label item | What it does for you |
|---|---|
| Model number | Matches the correct parts diagrams and part fit |
| Serial number | Helps confirm production run details |
| Engine model/type | Helps match engine-specific parts (filter, plug, carb items) |
Why it matters
Craftsman riding mowers can look nearly identical across years, but small changes in steering, deck drive, and electrical parts can change what fits. Confirming 917258873 before ordering prevents wrong-part returns and downtime.

Is it worth replacing a lawn mower engine?
Yes, replacing the engine on your Craftsman 917258873 front-engine lawn tractor is worth it when the tractor’s deck, steering, and transmission are in solid shape and the total engine swap cost stays well below the cost of a comparable replacement mower (a common cutoff is about 50%).
Quick decision checklist
- The mower deck shell is not rusted through and the spindles are serviceable
- Steering and front axle are tight (no severe slop or bent linkage)
- Transmission drives smoothly (no slipping, whining, or loss of pull)
- You can do the labor yourself or have a shop you trust
- The engine replacement includes the correct crankshaft size and PTO setup for your deck drive
Cost and effort: what to compare
Use this simple comparison to decide:
| Option | Upfront cost | Time/effort | Best when |
|---|---|---|---|
| Replace engine | Medium to high | Medium to high | Chassis and deck are strong; you want more years of service |
| Buy a new mower | High | Low | Multiple major systems are worn; you want minimal downtime |
| Repair existing engine | Low to medium | Medium | Problem is clearly fuel, ignition, or starter related |
Before you commit: rule out common “engine is bad” problems
Many no-start and no-crank complaints are caused by battery, safety switches, or fuel issues, not a failed engine.
- If it clicks but won’t crank, check battery voltage, cables, and solenoid connections
- If it cranks but won’t start, check fresh fuel, fuel flow, air filter, and spark
- Verify the PTO is disengaged and the brake/clutch is fully depressed (interlock circuit)
- Inspect wiring at the ignition switch and PTO switch for looseness or corrosion
- Check for a seized deck spindle or belt issue that overloads the engine when the PTO is engaged
Helpful walkthroughs:
- Riding lawn mower engine clicks but doesnt turn over video
- Riding lawn mower engine spins but wont start video
Why it matters
An engine swap can be a smart investment because it restores reliability and starting performance without replacing the entire tractor. If the rest of the Craftsman 917258873 is mechanically sound, you keep a proven chassis and avoid the learning curve and setup time of a new machine.

What brand engine does Craftsman use?
For Craftsman model 917258873 front-engine lawn tractor, the engine brand is Kohler. Craftsman has used several engine suppliers across its product lines, but this specific tractor model is built with a Kohler engine, so you should use Kohler engine identification when buying tune-up parts.
How to confirm the engine brand and ID on 917258873
Use the engine’s data tag, not the hood decal, to match the correct air filter, spark plug, oil filter, and fuel parts.
- Find the Kohler ID label on the blower housing, valve cover area, or near the starter
- Record the engine model and spec number (Kohler uses a spec number to pinpoint exact configuration)
- Compare the recorded ID to the parts you are replacing (filter shape, plug type, oil filter thread)
- If the tractor will not crank, verify the brake is fully set and the PTO is disengaged
- Keep the engine ID with your maintenance log for faster ordering next time
Craftsman engine brands: general guidance (not model-specific)
Craftsman has used different engine manufacturers on other riding mowers and tractors. Here is a quick reference:
| Craftsman equipment (varies by model) | Common engine brand used | What to check |
|---|---|---|
| Many lawn tractors | Briggs & Stratton | Model-type-code tag on engine |
| Some lawn tractors | Kohler | Model and spec number tag |
| Select models | Kawasaki | FR/FS/FX model tag |
Why it matters
Engine brand and the exact engine ID control parts fit. Ordering by tractor model alone can still lead to the wrong tune-up parts if the engine spec differs, so the Kohler model and spec number keeps maintenance accurate.

What year did Craftsman make the 917258873?
Craftsman model 917258873 does not have a single published “model year”; Craftsman tractors are identified by the model number plus the serial or product ID label on the machine. Use the serial number and any date code on your tractor to determine the exact build date.
Where to find the build date information
Check the tractor itself; this is the only reliable way to pin down the year for 917258873.
- Look under the seat for the product ID label (model and serial)
- Check the frame rail near the rear wheels for a sticker or stamped tag
- Write down the full serial number and any date code printed on the label
- If the label is missing, look for a stamped chassis number and compare it to parts diagrams
- Keep the engine model and code handy (often on the engine shroud) because it can help confirm the era
Using parts to confirm you are matching the right configuration
Parts will not tell you an exact year by themselves, but they help verify you are looking at the correct wiring, safety interlock setup, and drive configuration for your specific tractor.
| What you’re comparing | What it helps confirm | Example part used on this model |
|---|---|---|
| PTO control style | Electric PTO switch and wiring layout | Switch.pto.3 582107601 |
| Key switch style | Safety interlock and harness connections | Lawn tractor ignition switch 532140301 |
| Ground drive setup | Belt routing and drive system configuration | Lawn tractor ground drive belt, 1/2 x 84-1/2-in 532140218 |
Why it matters
The build date affects which electrical harness, safety switches, and belt routing your Craftsman riding mower uses. Matching parts to the exact configuration prevents ordering the wrong components and reduces repeat repairs.
