Where can I find my lawn mower engine model number?
On the Craftsman 247204112 rear-engine riding mower, the engine model number is usually printed on an engine ID label or stamped plate on the engine itself (not on the mower frame). Common locations include near the spark plug, near the muffler/heat shield area, on the recoil starter housing, or under the engine shroud; see the 247204112 operator’s manual for safety steps before you reach around the engine.
- On the sheet metal or valve cover area near the spark plug
- On or near the muffler side (often on a metal tag or label)
- On the recoil starter housing (if your engine uses a pull-start style housing)
- Under the engine shroud or top cover (you may need to remove a cover to see it)
- Near the carburetor or air cleaner base on some engines
The engine identification is often a small group of numbers and letters. Depending on the engine brand, you may see multiple fields.
| Label field | What it’s used for | Example format |
|---|---|---|
| Model | Identifies the engine family | 12Axxx-xxxx-x |
| Type/Spec | Narrows down exact configuration | 1234-01 |
| Code/Serial | Production date/serial info | YYMMDDxxxx |
We use the engine model and spec/type numbers to match the correct maintenance and repair parts (oil filter, air filter, fuel filter, ignition parts). That helps avoid ordering a part that fits a different version of the same engine family.
- Park on a flat surface and set the parking brake
- Remove the key and let the muffler cool completely
- Keep hands and clothing away from moving parts
- If you remove any shrouds, reinstall them before operating

Is it worth replacing a lawn mower engine?
Yes, it can be worth replacing the engine on your Craftsman 247204112 if the mower is otherwise in good shape and you are not near the end of its typical service life. This model’s operator guidance cites an average useful life of 7 years or 270 hours, so engine replacement makes the most sense when you are well under that range and the rest of the machine is solid. See the Craftsman 247204112 operator’s manual.
- Check hours first: Use the hour meter; if you are close to 270 hours, major repairs usually have a lower payoff.
- Confirm the failure is truly the engine: Fuel delivery, ignition, and safety interlocks can mimic engine failure.
- Price the full job: Engine, mounting hardware, belts, fluids, and any shop labor.
- Inspect the drivetrain and deck: Hydrostatic drive issues, spindle wear, or deck damage can change the math.
- Consider downtime: If you need the mower running quickly, a full engine swap may not be the fastest path.
Before committing to an engine replacement, we recommend checking these items because they are frequent no-start or poor-run culprits:
- Stale fuel or restricted fuel flow (inspect/replace the fuel filter 84001895)
- Dirty air filter (restricted airflow)
- Spark plug and ignition lead issues
- Blown fuse or wiring damage
- Safety interlock problems (seat switch, PTO switch, brake/lever position)
Use this simple comparison to decide:
| Situation on Craftsman 247204112 | Usually makes sense to… |
|---|---|
| Under ~50% of typical life (well under 7 years/270 hours) and deck/drivetrain are strong | Replace the engine |
| Near end of life (close to 7 years or 270 hours) or multiple major systems are worn | Replace the mower |
| Unsure if it’s fuel/air/electrical vs. engine damage | Diagnose first |
An engine swap is a big investment, but it can restore reliability and extend the usable life of your Craftsman 247204112. Verifying hours and ruling out fuel, air, and safety-switch issues helps you avoid replacing an engine when a smaller repair would solve the problem.

Is it worth repairing a lawn mower engine?
Yes, repairing the engine on your Craftsman 247204112 is usually worth it when the problem is external and serviceable (fuel delivery, air intake, ignition, routine maintenance). If the engine has internal damage or repair costs approach replacement cost, replacement is typically the better value.
Use these practical checkpoints before you spend money on parts or labor:
- Start with the easy wins: stale fuel, clogged air filter, plugged fuel filter, fouled spark plug, blown fuse, or safety interlock issues.
- Repair is favored when the mower is otherwise solid (deck, hydro drive, frame) and the issue is a normal wear item.
- Replace is favored when compression is low, the crankshaft is bent, the block is damaged, or it smokes heavily after basic service.
- Consider hours and age: this series is commonly referenced with an average useful life around 7 years or 270 hours in the operator guidance.
- Factor downtime: if you need it running quickly, a replacement engine (or mower) can be faster than a rebuild.
Before you assume the engine is “bad,” we recommend these steps from the troubleshooting flow in the Craftsman 247204112 operator’s manual:
- Verify PTO is disengaged and parking brake is set
- Confirm the spark plug wire is connected
- Drain and refill with fresh gasoline (fuel older than about 30 days can cause hard starting)
- Check for a clogged air filter and replace if dirty
- Check for a restricted fuel supply and replace the fuel filter
- Inspect the fuse if the starter won’t crank
| Symptom | Likely cause | Typical fix |
|---|---|---|
| Starts then dies | Restricted fuel flow | Replace inline fuel filter |
| Runs rough, lacks power | Dirty air filter | Replace air filter |
| Oil looks dirty, engine runs hot | Oil not serviced | Change oil and oil filter |
If your symptoms match, these model-compatible parts are a good place to start:
A “no-start” or “runs rough” complaint on the Craftsman 247204112 is often a maintenance issue, not a failed engine. Spending a little on filters and basic service can prevent bigger damage and extend engine life.

What are the common problems with Craftsman lawn mowers?
On the Craftsman 247204112 zero-turn riding mower, the most common problems we see are no-start conditions, rough running, overheating, uneven cutting, and excessive vibration. These issues are usually tied to routine maintenance items (fuel, air, oil, blades) or safety interlock switches covered in the 247204112 operator's manual.
Start with the basics that cause the highest percentage of complaints:
- Engine won’t start: PTO switch not off, parking brake not set, stale fuel, blown fuse, spark plug wire off
- Engine runs rough or surges: choke left on, dirty air filter, restricted fuel flow, loose spark plug wire
- Engine overheats: low oil level, grass/debris blocking cooling fins and shrouds
- Uneven cut: deck not leveled, dull/bent blades, uneven tire pressure
- Vibration: loose blades/spindle hardware, damaged blade
If the mower cranks but won’t fire, replacing a restricted fuel filter is a common fix; use the correct fuel filter 84001895.
| Symptom | Most likely cause | First action |
|---|---|---|
| No start | Safety interlock not satisfied | PTO off, levers neutral, brake set |
| Starts then dies | Fuel restriction or stale fuel | Drain old fuel, check filter |
| Runs rough | Dirty air filter | Inspect/replace air filter |
| Overheats | Debris on cooling system | Clean cooling fins/shrouds |
| Cuts uneven | Deck level or blade condition | Level deck, sharpen/replace blades |
Catching these problems early helps prevent bigger failures like belt damage, transmission strain, and premature engine wear. It also keeps the safety interlock system working correctly, which is critical on a zero-turn rider.
The 247204112 manual notes an average useful life of 7 years or 270 hours; staying on top of oil changes, air filter service, and blade checks is the best way to reach that target.
