Where can I find my lawn mower engine model number?
On the Craftsman lawn tractor model 917272243, the engine model number is listed in the engine section of the tractor documentation; for this tractor it identifies a Kohler engine (CV624) with a type number (65578). Use the engine’s ID label on the engine itself to match what you see in the 917272243 owner's manual.
Where to look on the engine
Most riding mower engines have an ID label or stamped plate on the engine shroud or valve cover area. Check these common spots first:
- On top of the engine cover (shroud) near the air cleaner
- On the side of the blower housing (near the recoil or starter area)
- Near the valve cover on twin-cylinder engines
- On the engine block near the starter or muffler (sometimes stamped)
- Under the hood, on a label facing upward (wipe dirt and oil off first)
What numbers you need (and how to use them)
For parts lookup and correct service info, we recommend recording all three fields from the engine ID:
- Model (engine family, for example CV624)
- Type (build specification, for example 65578)
- Code/serial (production date or serial)
Quick reference for this tractor
| Item | What it identifies | Example for 917272243 |
|---|---|---|
| Tractor model number | The mower/tractor platform | 917272243 |
| Engine model number | The engine family | CV624 |
| Engine type number | Exact engine configuration | 65578 |
Why it matters
The tractor model number tells us the chassis and deck configuration, but the engine model and type determine the correct ignition parts, starter components, gaskets, and tune-up items. Matching the engine ID prevents ordering the wrong Kohler parts.

Is it worth replacing a lawn mower engine?
Yes; replacing the engine on your Craftsman lawn tractor model 917272243 is worth it when the deck, frame, steering, and drive system are still solid and the total swap cost stays well below buying a comparable new tractor. If several major systems are worn, replacement is the better value.
Quick decision checklist
Use these checkpoints before you buy an engine or short block:
- Deck shell and frame are straight, with no rust-through or cracks
- Tractor drives consistently (no chronic slipping or loss of drive)
- Safety interlocks work (seat switch, brake, PTO); never bypass them
- The problem is truly engine-related, not multiple unrelated failures
- Your total parts plus labor estimate stays under about 50% of a comparable new tractor
For safety and service reminders (for example, never making adjustments with the engine running), follow the 917272243 owner's manual.
Cost and effort comparison
| Option | Best when | What to plan for |
|---|---|---|
| Replace engine | Tractor is in good shape overall | Wiring and controls hookup, pulley and belt alignment, break-in and tune-up |
| Replace short block | Bottom end is damaged but accessories are reusable | More teardown; transferring carburetor, ignition, and external parts |
| Replace tractor | Multiple systems are worn | Higher upfront cost; less repair time |
What to inspect on 917272243 before committing
These checks prevent installing a new engine and still having poor mowing performance:
- Clean grass and debris from under the mower deck (buildup is a common cause of poor cut and power loss)
- Inspect blade-drive components for binding or wear; a frozen idler pulley or worn belt can stop blades from turning
- Check for excessive vibration from worn or loose blades and damaged mandrels
- Rule out “engine-like” symptoms caused by basics: dirty air filter, stale fuel, clogged fuel filter, or a bad spark plug
If you are already in the deck area, replacing a worn idler can be smart preventive maintenance; the lawn tractor blade idler pulley 532177968 is one example of a deck-drive wear part used on this model.
Why it matters
An engine swap is a major investment. Confirming the deck, belts, pulleys, and safety systems are in good condition ensures the tractor will mow safely and perform well after the new engine is installed.

What the manual tells you (and what it does not)
The owner’s manual for 917272243 describes the tractor’s operation and maintenance schedule; the engine family is verified by the engine’s own ID tag.
| Item | Where to verify | Why it matters |
|---|---|---|
| Engine make/model | Engine ID label | Ensures correct tune-up parts and carburetor kits |
| Horsepower/displacement | Engine label/spec decal | Confirms performance and correct service specs |
| Starting system | Dash controls/manual | Helps diagnose no-crank and charging issues |
| Deck load/belt routing | Tractor diagrams/manual | Affects engine load and drive/deck belt setup |
Why it matters
Craftsman tractor model numbers identify the chassis and controls, but the engine ID determines the correct ignition, fuel, and filtration parts and many troubleshooting steps.
