Is it worth replacing a lawn mower engine?
Yes, replacing the engine on your Craftsman lawn tractor model 917258682 is worth it when the tractor’s deck, transmission, steering, and frame are still solid and the total engine job costs clearly less than buying a comparable new rider. If the tractor has multiple worn systems, replacement is usually the better value.
Quick decision checklist
- The mower deck shell is not cracked or badly rusted through.
- The transmission drives smoothly (no slipping, whining, or loss of power).
- Steering and front axle are tight enough to track straight.
- You can do the work (or pay for labor) without the total cost getting close to a new tractor.
- You plan to keep the tractor several more seasons.
Cost and effort: what to compare
Engine replacement cost is more than the engine itself. Plan for fluids, tune-up items, and time.
| Option | Upfront cost | Time/skill | Best when |
|---|---|---|---|
| Replace engine | Highest | Medium to high | Chassis and drivetrain are in great shape |
| Repair existing engine | Medium | Medium | Problem is limited (carb, ignition, fuel) |
| Replace tractor | Highest | Low | Multiple major systems are worn |
A practical rule we use: if the full engine replacement (parts + labor) is more than about half the price of a comparable new riding mower, replacement usually does not pay off.
Before you commit: rule out common “no-start” causes
Many “bad engine” symptoms are actually electrical or fuel issues.
- Battery weak or cables corroded (starter clicks, slow crank)
- Safety interlock switch issue (brake, seat, PTO)
- Old fuel or clogged fuel line/filter
- Dirty air filter or fouled spark plug
- Starter solenoid failing (single click, no crank)
If you’re hearing a click and no crank, the starter circuit is a smart first check; see riding lawn mower engine clicks but doesnt turn over video. If the solenoid is the culprit on this model, solenoid 532146154 is a common replacement part.
Why it matters
An engine swap can extend the life of a good Craftsman tractor, but it only makes sense when the rest of the machine (deck, belts, spindles, steering, and drivetrain) will not immediately need expensive repairs.

Does Craftsman use Kohler engines?
Yes. Craftsman has used Kohler engines on some riding mowers and tractors, but it depends on the specific model and production run. For the Craftsman lawn tractor model 917258682, the engine brand is determined by the engine ID tag on the engine itself.
How to tell what engine is on model 917258682
Look for the engine identification label (usually on the blower housing, valve cover area, or near the starter). That label tells you the engine manufacturer and the exact engine model/spec.
- Clean the label area so the numbers are readable.
- Record the engine model and spec numbers (not just horsepower).
- Compare the engine brand name on the tag (Kohler, Briggs and Stratton, Tecumseh, etc.).
- Use the engine model/spec to match tune-up parts (spark plug, air filter, fuel filter).
- If the label is missing, use the tractor’s product ID decals and the engine’s physical features (carburetor style, air box shape) to narrow it down.
What “Craftsman uses Kohler” usually means
Craftsman sources engines from multiple manufacturers across different mower lines. You will see Kohler more often on certain higher-trim or specific series, while other models may use different engine brands.
| What you’re checking | Where to look | What it tells you |
|---|---|---|
| Engine brand | Engine ID tag | Kohler vs other manufacturer |
| Engine model/spec | Engine ID tag | Exact service parts and settings |
| Tractor model | Tractor frame tag | Which parts diagrams apply |
Why it matters
The engine brand and spec determine the correct maintenance parts and troubleshooting steps. For example, a no-start issue can point you toward the right ignition, fuel, and safety-interlock checks once you know the engine family.
For common starting symptoms on riding mowers, we recommend riding lawn mower engine spins but wont start video.

Where can I find my lawn mower engine model number?
On your Craftsman riding lawn tractor model 917258682, the engine model number is printed on an engine ID label or stamped into the metal on the engine itself (not on the mower frame). We typically find it on top of the engine under the plastic engine cover, or on the side of the blower housing near the spark plug area.
Where to look first (fastest checks)
- Lift the hood and look for a white or silver ID label on the engine shroud
- Check the top of the engine under the plastic cover (common on twin-cylinder engines)
- Look on the side of the engine blower housing (often easier to see on some engines)
- Check near the valve cover, starter, or muffler heat shield for a stamped code
- Wipe off dirt and oil; the label is often hidden by grass dust
What the engine number looks like
Most riding mower engines use a small label or stamping that includes:
- Model (engine family/model)
- Type (variation of that model)
- Code or serial (build date/serial)
| What you need | Why you need it | Where you use it |
|---|---|---|
| Engine model number | Identifies the exact engine design | Engine tune-up parts, carburetor, starter, ignition parts |
| Engine type/spec | Matches the correct sub-variant | Gaskets, fuel system parts, governor linkages |
| Engine code/serial | Confirms production version | Service bulletins and exact part lookups |
Why it matters
Your tractor model number (917258682) identifies the mower chassis and deck, but the engine model number identifies the engine itself. Having both prevents ordering the wrong ignition parts, fuel parts, or starter components.

What engine does Craftsman riding mower use?
The Craftsman riding mower model 917258682 uses a gasoline-powered, single-cylinder small engine (the exact engine brand and horsepower vary by the tractor’s build and any engine swaps over its life). We confirm the engine type by checking the engine ID tag and matching it to the correct tune-up and starting parts.
How to identify the exact engine on model 917258682
Look for the engine identification label (usually on the blower housing, valve cover area, or near the starter). Record these items:
- Engine manufacturer (commonly Briggs & Stratton, Kohler, or Tecumseh on older Craftsman tractors)
- Model number
- Type/spec code
- Code/date (helps confirm the exact version)
- Shaft orientation and mounting pattern (useful when ordering belts and pulleys)
If the tractor cranks slowly or only clicks, the starting circuit can mimic an “engine problem”. The quickest next step is to follow riding lawn mower engine clicks but doesnt turn over video.
What we use the engine ID for (and why it matters)
The engine tag determines the correct maintenance and ignition/fuel parts, including:
- Spark plug and air filter style
- Carburetor kit or fuel shutoff parts
- Starter, starter drive, and charging system components
- Oil type and capacity guidance for that engine family
Common symptoms and what they usually point to
| Symptom | Most common cause | First check |
|---|---|---|
| Clicks but won’t crank | Weak battery, bad solenoid, poor cable connection | Battery voltage and cable ends |
| Cranks but won’t start | Fuel delivery or ignition issue | Fresh fuel, spark at plug |
| Starts then dies | Safety interlock, fuel restriction | Brake switch, fuel flow |
Parts that often get replaced during “engine” troubleshooting
On Craftsman tractors like 917258682, these are frequent culprits:
- Starter solenoid (a common no-crank cause); see solenoid 532146154
- Ground drive and deck belts (if the tractor moves or mows poorly after engine work); see v-belt 532138255 and lawn tractor v-belt 532144959
Why it matters
Ordering by tractor model alone can miss the correct engine-specific parts. Using the engine ID tag prevents wrong spark plugs, filters, and starting components, and it speeds up diagnosis when the mower won’t crank or won’t start.
