Does Craftsman use Kohler engines?
Yes. Craftsman uses Kohler engines on some riding mowers and tractors, but not on every model. For Craftsman model 917258557, the engine brand depends on the specific engine installed on your tractor, so we recommend confirming it from the engine ID tag before ordering engine parts.
How to confirm which engine your Craftsman 917258557 has
Look for the engine identification label (usually on the blower housing, valve cover area, or near the starter). Use these checks:
- Find the engine brand (Kohler, Briggs and Stratton, Tecumseh, etc.) printed on the shroud or tag
- Record the engine model and spec numbers (often required for tune-up and carburetor parts)
- Compare the tag info to what is stamped or printed on the engine cover
- If the tag is missing, note the engine features (single vs twin cylinder, air filter style, muffler shape)
- Match the engine info to the correct parts diagrams before purchasing
What this means for parts and maintenance
Even when two Craftsman tractors share the same tractor model family, the engine can vary by production run or prior replacement. That is why engine tag information matters for items like spark plugs, air filters, fuel filters, and mufflers.
Common tractor parts that are not engine-brand specific
These parts are selected by tractor deck and drive system, not by whether the engine is Kohler:
- Mower deck blades and mandrel components
- Ground drive belt and blade drive belt
- Steering and wheel hardware
- Deck leveling and idler pulley parts
If you are servicing the cutting system on this tractor, a common match is the husqvarna lawn tractor mulching blade, 21-in 532134149.
Quick comparison: tractor model vs engine model
| Item | Where to find it | What it controls |
|---|---|---|
| Tractor model (917258557) | Tractor frame tag (often under seat or on frame) | Deck, belts, steering, chassis parts |
| Engine model/spec | Engine ID tag on the engine | Tune-up parts, fuel system parts, engine-specific components |
Why it matters
Ordering by the correct engine model prevents wrong-fit tune-up parts and helps troubleshooting issues like no-start, hard starting, or poor power under load.
For starting problems, we also recommend riding lawn mower engine spins but wont start video.

How much does it cost to replace a riding lawn mower engine?
For a Craftsman riding lawn tractor like model 917258557, a full engine replacement typically costs $260 to $1,800 installed, depending on the engine type, labor rates, and whether related drive or deck parts need service at the same time.
What drives the total price
Engine replacement cost is usually a mix of parts, labor, and “while we’re in there” maintenance.
- Engine cost: varies widely by horsepower, shaft size, and charging system
- Labor time: commonly around 6 hours for a riding mower engine swap
- Extra parts: belts, pulleys, hardware, and fuel system items may be needed
- Shop rates: local labor rates can change the total significantly
- Condition of the tractor: rusted fasteners, worn mounts, or wiring issues add time
Typical cost breakdown (installed)
| Cost item | Typical range | Notes |
|---|---|---|
| Replacement engine | $200 to $1,400 | Biggest variable; must match shaft and mounting specs |
| Labor | $200 to $600 | Often based on ~6 hours |
| Misc. parts and supplies | $20 to $200 | Fuel line, clamps, oil, filter, hardware |
| Estimated total | $260 to $1,800 | Most common real-world range |
Parts that often get checked or replaced during an engine swap
Even if you only replace the engine, we often see these items inspected because they affect performance and reliability.
- Ground drive belt (cracking, glazing, slipping): lawn tractor ground drive belt 532140294
- Blade drive belt (deck engagement issues): lawn tractor drive belt 532144200
- Engine pulley (wobble, worn grooves): engine pulley 532140186
- Muffler (rust-through, excessive noise): muffler 532159420
Why it matters
An engine replacement is one of the highest-cost repairs on a riding mower. Comparing the installed cost to the tractor’s overall condition (deck, transmission, steering, and belts) helps you decide whether to repair now or invest in a different machine.

What engine does Craftsman riding mower use?
Craftsman riding mowers use different engines by model and build date. For Craftsman model 917258557, the correct way to identify the exact engine is to read the engine ID tag on the engine itself (manufacturer, model, type, and code); that ID is what we use to match tune-up and replacement parts.
How to identify the engine on model 917258557
Find the engine identification label or stamped tag, then write down every line exactly.
- Engine manufacturer name (commonly Briggs & Stratton, Kohler, or Tecumseh)
- Engine model number
- Type/spec number
- Code or date code
- Any additional spec or trim numbers
Where the engine ID tag is usually located
On most front-engine lawn tractors, the ID is easy to spot once the hood is open.
- Blower housing (fan shroud) near the recoil or air intake area
- Valve cover area
- Near the starter motor
- On the engine block above the PTO/clutch area
Why we use the engine ID (not just the tractor model)
The same tractor model can ship with different engines across production runs, and the engine ID controls the exact maintenance parts and settings.
| What you are trying to match | What number to use | Example outcome |
|---|---|---|
| Air filter, spark plug, fuel filter | Engine model and type/spec | Correct tune-up kit parts |
| Carburetor or starter parts | Engine model plus code | Correct revision/version |
| Belts and deck hardware | Tractor model 917258557 | Correct deck and drive parts |
Related parts that affect “power” but are not engine parts
If the engine runs but the tractor feels weak or the blades slip, these deck and drive parts are common causes.
- Slipping drive: lawn tractor ground drive belt, 1/2 x 82-in 532140294
- Blade engagement slip: lawn tractor drive belt 532144200
- Poor cut or vibration: husqvarna lawn tractor mandrel assembly 532130794
Why it matters
Using the engine ID prevents ordering the wrong spark plug, air filter, carburetor, or starter parts and helps restore reliable starting and full cutting power.
