Owner’s manual
What kind of engine does a Craftsman riding lawn mower have?
The Craftsman riding lawn mower model 917258911 uses a gas-powered small engine (the manual covers engine maintenance items like oil type, air filter, and spark plug). For the exact engine make, model, and horsepower rating used on your tractor, match the engine identification numbers shown in the 917258911 owner's manual.
How to identify the exact engine on model 917258911
Use these quick checks to confirm what you have before ordering engine parts or doing a tune-up:
- Look for the engine ID label on the engine shroud, valve cover, or blower housing
- Record the engine model, type, and code (or spec number)
- Compare those numbers to the engine section in the manual and parts diagrams
- Verify whether your tractor has a single-cylinder or twin-cylinder layout by the cylinder head(s)
- Use the engine ID to select the correct spark plug, air filter, and fuel system parts
What the manual tells you about the engine (and why it helps)
Even when the brand or horsepower varies by production run, the manual guidance still applies for keeping the engine reliable:
| Maintenance item | What to do | Why it matters |
|---|---|---|
| Engine oil | Check level before use; change on schedule | Prevents wear and overheating |
| Air filter / air screen | Clean or replace as needed | Helps starting and power under load |
| Spark plug | Inspect and replace when worn | Reduces misfires and hard starting |
| Fuel system | Use fresh fuel; follow storage steps | Prevents varnish and no-start issues |
Common symptoms that point to an engine or starting issue
If you are asking about the engine because it will not start or crank, these are the most common causes on riding tractors:
- Weak battery or corroded battery cables
- Faulty safety interlock switch (seat, brake, or PTO circuit)
- Bad starter solenoid (a click with no crank is a common clue)
- Stale fuel or a restricted fuel path
- Dirty air filter or fouled spark plug

Is it worth replacing a lawn mower engine?
Yes, replacing the engine on your Craftsman 917258911 front-engine lawn tractor is worth it when the tractor’s deck, steering, and drive system are still solid and you want more years of reliable mowing. It is usually not worth it when multiple major systems are worn and the total repair cost approaches the price of a comparable replacement tractor.
Quick decision checklist
- The mower deck is not rusted through and still cuts evenly after leveling
- The tractor drives smoothly (no slipping, belt smoke, or loss of motion)
- Steering and front end feel tight (no severe play in linkage)
- You can complete routine maintenance safely (oil, filters, belts)
- You are comfortable doing a larger DIY repair and setup
Costs and condition: a simple comparison
| If your tractor is like this | Engine replacement usually makes sense | A different solution usually makes sense |
|---|---|---|
| Deck and chassis are in good shape | Yes | No |
| Multiple wear items are failing (belts, pulleys, steering parts) | Sometimes | Often |
| You need it dependable for weekly mowing | Yes (after full tune-up) | If repairs stack up |
| You already need several high-cost parts | Less often | More often |
What to inspect before you commit
Use the maintenance and service sections in the owner's manual to evaluate the tractor’s overall condition and safety.
- Drive belts and pulleys: Worn belts or frozen pulleys can add significant cost; a common wear item is the lawn tractor ground drive belt, 1/2 x 84-1/2-in 532140218.
- Blade drive system: If the deck drive is noisy or binds, check idlers and mandrels; a common wear item is the lawn tractor idler pulley 532139245.
- Safety interlocks: The manual emphasizes not tampering with safety devices and checking operation regularly; a bad interlock can mimic engine problems.
- Fuel system condition: Old fuel and restricted filters cause hard starting and poor running; the manual calls for replacing the in-line fuel filter once each season.
Why it matters
An engine swap only pays off when it restores a tractor that is already structurally sound. If the deck, belts, pulleys, and safety systems are neglected, a new engine can still leave you with poor cut quality, drive issues, or unsafe operation.

Where can I find my lawn mower engine model number?
On Craftsman tractor model 917258911, the engine model number is on the blower housing of the engine (the shroud covering the flywheel and cooling fins). Your tractor model number is on the model plate under the seat; both numbers help us match the correct parts and diagrams in the owner's manual.
Where to look (quick checklist)
- Park on a flat surface, set the parking brake, and remove the key
- Let the engine cool completely
- Lift the hood and locate the blower housing (typically the top/front shroud)
- Look for a label or stamped ID on the blower housing
- Write down engine model and any type/spec numbers shown
What you should record
Use this as a guide when you copy the information:
| Item to record | Where you’ll find it | Example for this tractor |
|---|---|---|
| Tractor model number | Model plate under the seat | 917258911 |
| Engine model number | Blower housing | CV22S |
| Engine type number | Blower housing label | 67515 |
Why it matters
The tractor model number identifies the chassis and mower deck parts; the engine model and type numbers identify the correct ignition, fuel system, and other engine-specific parts. Using all three prevents ordering the wrong solenoid, belt, or fuel tank.
Related parts you may match by engine/tractor ID

What year did Craftsman make the 917258911?
Craftsman model 917258911 does not map to one single “model year”; it was produced across a range of years, and the exact build date is identified from the tractor’s serial number/date code. Use the identification steps in the owner's manual to locate the model and serial information and confirm the manufacturing date.
How to find the exact build year on your tractor
We use the tractor’s ID label (typically under the seat or on the frame) to determine the build date.
- Park on a flat surface, set the parking brake, and remove the key.
- Lift the seat and look for the model/serial label on the fender pan or frame.
- Write down the serial number exactly as shown.
- Look for a date code embedded in the serial number (format varies by production run).
- If the label is missing or unreadable, check for a second label on the frame rails near the engine.
What the model number tells you (and what it does not)
On Craftsman tractors, the 917 prefix identifies the product family and manufacturing source, but it does not reliably indicate a single calendar year by itself. Your 917258911 parts breakdown in the manual confirms the model identity and configuration (for example, the engine listing shows Kohler model CV22-PS67515), but the year still comes from the serial/date code.
Quick reference
| Identifier | What it helps with | What it does not confirm |
|---|---|---|
| Model number (917258911) | Correct parts diagrams and assemblies | Exact production year |
| Serial number/date code | Manufacturing date window | Parts compatibility by itself |
| Engine model (CV22-PS67515) | Engine-specific service parts | Tractor model year |
Why it matters
The build year affects small but important fit details like wiring harness revisions, safety interlock switch styles, and deck/drive belt routing. Confirming the serial/date code helps us match the right electrical and chassis parts the first time.
Parts that commonly vary by production run
If you are troubleshooting starting or safety issues while you are checking the ID label, these parts are often involved:
- Solenoid 532146154 (starter solenoid)
- Push-in interlock switch 532176138 (seat/brake safety circuit)
- Switch.pto.3 582107601 (PTO engagement switch)
