Does Craftsman use Kohler engines?
Yes. Craftsman has used Kohler engines on some riding mower and lawn tractor models, but many Craftsman tractors (including older 12-hp, 38-inch front-engine designs like model 917254660) are more commonly found with Briggs & Stratton engines depending on the exact build and engine spec.
How to tell what engine is on your 917254660
Check the engine identification label on the engine itself (not the tractor frame). On most riding lawn tractors, you will find it:
- On the blower housing (recoil starter shroud) or valve cover area
- Near the muffler or above the spark plug
- On a sticker or stamped metal tag with model, type, and code
- Sometimes on the side of the engine block near the dipstick
If you are shopping parts, match parts to the engine model and type code, not just the Craftsman tractor model number.
Common engine brands you may see on Craftsman tractors
Craftsman has sourced engines from multiple manufacturers over the years. The most common ones include:
- Briggs & Stratton
- Kohler
- Kawasaki (on select models)
Quick comparison
| Engine brand | Typical use on Craftsman tractors | What to match for parts |
|---|---|---|
| Briggs & Stratton | Very common across many models | Engine model, type, code |
| Kohler | Used on some models and series | Engine model and spec number |
| Kawasaki | Used on select higher-end models | Engine model and spec |
Why it matters
Engine parts (carburetor components, ignition parts, starter parts, gaskets, and filters) are engine-specific. Even if two tractors share the same deck size, the correct tune-up and repair parts can differ by engine manufacturer and spec.

What model number is the Craftsman 917254660?
The model number for this Craftsman front-engine lawn tractor is 917254660. That number is the correct identifier to use when matching parts (like belts, pulleys, and electrical switches) to your exact 38-inch, 12-hp riding lawn tractor.
Where to find and confirm the model number
Use the 917254660 model number when you search parts diagrams and when you compare part fit.
- Check the model tag under the seat, on the frame rail, or near the engine compartment
- Write down the full model number exactly as shown (all digits)
- If you see extra numbers, those are often serial or product numbers; keep them for reference
- Use the model number to avoid ordering the wrong deck belt, drive belt, or steering part
Why the model number matters for parts fit
Many Craftsman riding mowers look similar but use different deck sizes, belt lengths, and safety interlock wiring. Using 917254660 helps ensure the parts you choose match your tractor’s configuration.
Examples of model-matched parts on this page
| What you are fixing | Common part type | Example part on this page |
|---|---|---|
| Tractor will not crank | Starter circuit component | Solenoid 532146154 |
| Blades will not engage or belt slips | Deck drive component | Lawn tractor blade drive belt 532106085 |
| Tractor will not move | Ground drive component | V-belt 532125907 |
Quick tip if your mower is labeled differently
If your hood or decals show a marketing name (for example, a series name), the model number is still the best match key for Craftsman parts lookup. For help locating the tag, use how to find your appliance model number (and what it means for parts).

What is the average lifespan of 917254660?
A Craftsman 917254660 38-inch, 12-hp riding lawn tractor typically lasts 10 to 15 years with routine maintenance and timely belt, blade, and steering wear-part replacement. Heavy mowing hours, rough terrain, and poor storage shorten life; consistent service extends it.
What most affects lifespan
- Engine hours and load: frequent tall, wet grass mowing increases wear.
- Deck drive system condition: worn belts and idlers slip, overheat, and stress spindles.
- Steering and front axle wear: loose linkage accelerates tire and bushing wear.
- Storage: covered, dry storage prevents corrosion and electrical issues.
- Fuel care: stale fuel and dirty caps/vents cause hard starting and carb problems.
Maintenance milestones we recommend
| Interval | What to do | Why it matters |
|---|---|---|
| Every mow | Check oil level, clear debris from deck | Prevents overheating and engine damage |
| Every 25 hours | Inspect deck belt, blade condition, tire pressure | Keeps cut quality and reduces strain |
| Seasonally | Replace worn belts, sharpen/replace blades, check steering play | Avoids breakdowns mid-season |
Parts that commonly determine “end of life” (and are replaceable)
If performance drops, these wear items often restore reliability:
- Deck belt: lawn tractor blade drive belt 532106085
- Idler pulley: lawn mower idler pulley 532121316
- Blade: lawn tractor blade 532143978
- Steering linkage: tie rod 532170162 and drag link 532105727
Why it matters
Most “tractor is worn out” complaints come from neglected wear parts, not the tractor frame itself. Replacing a slipping belt, noisy pulley, or loose steering linkage on the 917254660 often brings back safe operation and a clean cut.
