Does Craftsman use Kohler engines?
Yes, Craftsman uses Kohler engines on some riding mowers and tractors, but it depends on the specific model and production run. For the Craftsman lawn tractor model 917252531, the tractor and engine each have their own model number; we use the engine model number (from the blower housing) to identify the exact engine brand and parts. See the 917252531 owner's manual.
Use these checks to confirm what engine is on your tractor:
- Lift the seat and locate the tractor model plate (confirms 917252531).
- Find the engine model number on the blower housing (this identifies the engine maker and spec).
- Compare the engine label to common engine brands used on Craftsman tractors (Kohler, Briggs and Stratton, Tecumseh, etc.).
- Use the engine model number when ordering tune-up parts like spark plugs, air filter, and fuel filter.
- If you are replacing drive components, use the tractor model number for chassis and deck parts.
Craftsman is the equipment brand; engines are commonly sourced from multiple manufacturers. That is why the manual notes that the tractor has its own model number and the engine has its own model number.
| What you’re identifying | Where to look | What it’s used for |
|---|---|---|
| Tractor model (917252531) | Model plate under the seat | Deck, belts, steering, chassis parts |
| Engine model number | Label on blower housing | Engine parts and engine brand confirmation |
Engine brand affects the correct maintenance parts and settings (for example, the correct air filter style and spark plug type). Using the engine model number prevents ordering the wrong parts even when the tractor model is correct.

How much does it cost to replace a riding lawn mower engine?
For the Craftsman lawn tractor model 917252531, a full engine replacement typically runs about $260 to $1,800 installed, depending on the engine type, labor rates, and whether related items (belts, wiring, battery) also need service. Plan on around 6 labor hours for a riding mower engine swap.
- Engine price: new, used, or remanufactured engines vary widely
- Labor time and shop rate: most of the bill is labor if the engine is hard to access
- Extra parts often replaced at the same time: drive belts, fuel filter, spark plug, battery cables
- Condition of mounting hardware and wiring: rusted bolts and damaged connectors add time
- Deck and drivetrain setup after install: adjustments and test run time
| Cost item | Typical range | Notes |
|---|---|---|
| Engine (part only) | $150 to $1,400 | Biggest variable; depends on horsepower and brand family |
| Labor | $100 to $600 | Often 4 to 8 hours total |
| Fluids, tune-up items, small hardware | $10 to $150 | Oil, filter (if equipped), fuel line clamps, fasteners |
| Total installed | $260 to $1,800 | Common real-world range |
Many “dead engine” symptoms are actually battery, starter, or fuel issues. The troubleshooting section in the 917252531 owner’s manual covers checks like battery terminals, wiring, ignition switch, and solenoid/starter.
- Recharge or replace the battery; clean and tighten terminals
- Inspect wiring connections for looseness or corrosion
- Test the solenoid and starter if you hear clicking
- Replace the spark plug and fuel filter if it cranks but will not start
- Drain old fuel and refill with fresh gasoline (especially after storage)
An engine replacement is one of the highest-cost repairs on a riding mower. Confirming the problem first helps you avoid paying for an engine when a battery, solenoid, or fuel issue is the real cause.

How do I find the model number on my 917252531?
On the Craftsman lawn tractor model 917252531, the tractor model number and serial number are printed on the model plate under the seat. Lift the seat and read the plate; record both numbers for ordering the correct parts and manuals.
- Park on a flat surface, set the parking brake, and turn the key off
- Let the engine and muffler cool completely
- Lift the seat to access the identification plate underneath
- Write down the model number and serial number exactly as shown
- Use those numbers when searching diagrams and ordering parts
Your tractor and engine use different identification plates. For this Craftsman tractor, the manual notes the tractor plate is under the seat, and the engine model number is on the engine blower housing.
| What you need | Where it’s found | What it’s used for |
|---|---|---|
| Tractor model number (917252531) | Plate under the seat | Correct tractor parts, deck parts, belts, steering parts |
| Tractor serial number | Plate under the seat | Identifying the exact production version |
| Engine model number | Engine blower housing | Engine-specific parts and service items |
Using the exact model and serial number helps us match the right diagrams and parts for your specific build, especially for common wear items like a drive belt, mower deck components, and steering parts.
- Use the 917252531 owner’s manual to confirm the model plate location and see the parts lists and diagrams.
