Is it worth replacing a lawn mower engine?
Replacing the engine on your Craftsman lawn tractor model 917272245 is worth it when the tractor’s deck, chassis, steering, and drive system are still solid and the total engine-swap cost stays well below the cost of replacing the whole tractor. If multiple major systems are worn, replacement makes more sense.
- The mower deck is not rusted through and still cuts evenly after cleaning and leveling.
- The tractor still drives normally (no slipping or loss of drive).
- You are not also chasing major vibration issues from worn blades or bent mandrels.
- You can do basic DIY work (belt routing, wiring connections, throttle/choke linkage).
- The engine failure is confirmed (not a fuel, spark, or safety-interlock issue).
Use this simple guideline to decide quickly.
| Situation | What it usually means | Best move |
|---|---|---|
| Engine is bad but tractor is otherwise strong | You are extending the life of a good machine | Replace engine |
| Engine is bad and drive/deck also need work | Costs stack up fast | Consider replacing tractor |
| Engine “seems dead” but basics not checked | Often a starting or fuel issue | Troubleshoot first |
Your 917272245 manual’s troubleshooting chart points to several non-engine causes of poor running or power loss. Before pricing an engine, we recommend these checks:
- Clean grass and debris from under the deck and around the engine cooling fins/air screen.
- Check oil level and change dirty oil.
- Clean or replace the air filter.
- Replace or regap the spark plug; make sure the plug wire is tight.
- Replace the fuel filter and drain stale fuel; refill with fresh gasoline.
For step-by-step guidance and model-specific procedures, use the owner's manual.
An engine swap is a big investment in time and money. If the real problem is maintenance related (dirty air filter, stale fuel, clogged cooling fins) you can restore power and reliability without replacing the engine.

What brand engine does Craftsman use?
For the Craftsman lawn tractor model 917272245, the engine brand is Kohler. This model uses a Kohler engine identified in the documentation as Kohler CV624 (Type 65578); you can confirm the exact engine labeling and service details in the owner's manual.
Knowing the engine brand and model helps you match the correct tune-up and drive components (filters, belts, ignition parts) and follow the right maintenance intervals.
- Use Kohler-specific engine service specs (oil type, spark plug gap, air filter style)
- Order parts by the tractor model number 917272245 when possible
- Use the engine model CV624 when shopping engine-only parts
- Keep fuel fresh (most small engines run best on fuel used within about 30 days)
- Follow the maintenance schedule to prevent hard-start and power-loss issues
| Item | What to look for | Example for this tractor |
|---|---|---|
| Tractor model | ID on the tractor and in documentation | 917272245 |
| Engine brand | Name on engine shroud/labels | Kohler |
| Engine model/type | Engine tag or manual engine section | CV624, Type 65578 |
Even though the engine is Kohler, many common wear items on the tractor are chassis or deck related. If you are troubleshooting slipping drive or poor movement, the ground drive belt is a frequent check.
- Lawn tractor ground drive belt, 1/2 x 82-in 532140294 (loss of drive, squealing, glazing)
- Pto switch 582107601 (mower deck will not engage)
- Lawn tractor blade idler pulley 532177968 (deck belt noise, wobble)
- Husqvarna lawn tractor idler arm return spring 532105709 (belt tension problems)
Craftsman tractors can be built with different engine suppliers across model lines. For 917272245, the Kohler CV624 identification keeps you from buying the wrong engine service parts and helps you use the correct adjustment and troubleshooting procedures.

What year is my Craftsman mower serial number lookup?
The year of a Craftsman mower is not determined by a single universal “serial number date code” format. For Craftsman lawn tractors like model 917272245, we identify the build date by matching the product ID and serial number format shown on the tractor’s ID label to the decoding guidance in the owner's manual.
Look for the product identification label in one of these common spots:
- Under the seat pan (lift the seat)
- On the frame near the rear wheels
- Under the hood near the engine compartment
- Along the left or right side of the chassis rail
Write down both values:
- Model number (for this tractor: 917272245)
- Serial number (often a longer mix of numbers and letters)
Some Craftsman equipment uses a date-style code where groups of digits represent month, day, and year. Other tractors use a different serial format where the date is not in a simple MMDDYY pattern. The most reliable method is to compare your exact serial number pattern to the decoding notes for your tractor family.
| If your serial number starts with | What it usually means | What to do next |
|---|---|---|
| 4 to 6 digits that look like a date | Possible MMDDYY-style date code | Confirm the grouping using the manual guidance |
| Letters plus numbers (long string) | Factory/sequence code, not a simple date | Use the manual’s ID label section and keep the full string |
| Missing/illegible label | Date code cannot be read | Replace the label or use other documentation tied to the tractor |
Knowing the correct year helps us match the right parts and diagrams for your Craftsman lawn tractor, especially for wear items like belts, steering parts, and deck hardware.
If you are already working on the front end or wheels while checking the label, common items on this model include the axle cap 532104757 and the wizard lawn tractor axle flange bearing 532009040.

Where can I find my lawn mower engine model number?
On your Craftsman lawn tractor model 917272245, the engine model number is printed on the engine identification label (a sticker or metal tag) attached directly to the engine. For this tractor, the engine listing in the owner's manual identifies a Kohler engine model number CV624 with type number 65578.
Clean off grass and oil first so the numbers are readable. Check these spots:
- On the blower housing/engine shroud (top or side of the engine)
- On the sheet metal near the muffler or heat shield
- Near the spark plug side of the engine
- Under the top engine cover (shroud) if the label is tucked underneath
- Near the starter/solenoid area on the engine
Record every line on the label, not just one number.
| Label field | What it looks like | What it’s used for |
|---|---|---|
| Engine model | CV624 | Matches the correct engine family |
| Type number | 65578 | Matches the exact engine build/spec |
| Serial number | A longer unique number | Helps confirm the exact production run |
The tractor model number (917272245) is used for chassis, deck, and steering parts, but engine parts are matched to the engine model and type. Using CV624 and 65578 prevents ordering the wrong ignition, fuel, or starting components.
