Do Craftsman mowers use Briggs and Stratton engines?
Yes. The Craftsman model 247289330 uses a Briggs & Stratton V-twin engine (the manual lists a Briggs & Stratton Platinum V-Twin and shows engine model 407777-0717-B1). Craftsman mowers can also use other engine brands depending on the specific model and series.
What this means for parts and service
When you confirm the engine make and engine model, you can match the correct tune-up and repair parts (spark plug, air filter, fuel filter, carburetor parts) and follow the right maintenance specs.
- Check the engine ID label on the engine shroud or valve cover for the exact engine model and type
- Use the engine model to select the correct Briggs & Stratton parts list and repair manual
- Follow the oil and fuel recommendations listed for your tractor
- Keep safety interlocks and PTO controls working correctly before mowing
Quick model-specific details (247289330)
| Item | What we use for this model | Why it helps |
|---|---|---|

| Fuel type | Unleaded gasoline | Helps prevent starting and running issues |
| Spark plug listed | Champion RC12YC | Common tune-up reference |
Why it matters
Ordering engine parts by “Craftsman mower” alone often leads to mismatches. Using the 247289330 tractor model plus the Briggs & Stratton engine model keeps maintenance (oil changes, spark plug replacement, carburetor service) accurate and reduces downtime.

How much does it cost to replace a riding lawn mower engine?
For the Craftsman 247289330 riding mower, engine replacement typically costs about $1,200 to $3,500 total (engine plus labor). The engine itself is often the biggest expense, and installation commonly takes around 4 to 8 labor hours, depending on shop rates and any extra parts needed.
What drives the total cost
- Engine price: New replacement engines for riding mowers commonly run $900 to $2,000+.
- Labor: Many shops charge $100 to $180 per hour.
- Extra parts and supplies: Belts, hardware, fuel line clamps, oil, filter, and shop supplies can add up.
- Why the engine failed: If the failure involved overheating, fuel contamination, or vibration, you may need additional repairs.
- Availability: In-stock engines and local shop scheduling can affect the final bill.
Typical cost breakdown (example ranges)
| Cost item | Typical range | Notes |
|---|---|---|
| Replacement engine | $900 to $2,000+ | Varies by engine model and spec |
| Labor (4 to 8 hours) | $400 to $1,440 | Based on $100 to $180/hr |
| Fluids, tune-up items, misc. parts | $50 to $250 | Oil, filter, spark plug, clamps, hardware |
| Estimated total | $1,200 to $3,500 | Most common real-world range |
Before you replace the engine, check these quick items
If the mower will not start or runs poorly, a few basics can mimic “bad engine” symptoms. Our troubleshooting steps in the 247289330 owner's manual cover common no-start and rough-running causes.
- Confirm the PTO is disengaged and the parking brake is set
- Check fresh fuel (gas older than ~30 days can cause hard starting)
- Inspect the fuel line for blockage and verify the cap vent is open
- Check the spark plug wire connection and spark plug condition
- Inspect and service the air cleaner
Why it matters
An engine swap is one of the highest-cost repairs on a riding mower. Verifying fuel, ignition, and airflow issues first can prevent paying for an engine when a lower-cost fix (like a plug, filter, or fuel system cleaning) solves the problem.

Is it worth replacing a lawn mower engine?
Yes, replacing the engine on your Craftsman 247289330 zero-turn riding lawn mower is worth it when the deck, frame, steering, and drive system are still solid and the total engine swap cost stays well below the cost of a comparable new mower. If the mower has multiple major wear issues, replacement usually makes more sense.
Quick decision checklist
- The mower deck is not rusted through and the spindles feel tight (no grinding or wobble).
- The transaxle/drive pulls strongly and does not slip when hot.
- Wiring and safety interlocks are intact (no hacked or bypassed switches).
- You can do the work safely or have a shop install the engine.
- The engine replacement cost (engine, hardware, belts, labor) is under about half the price of a comparable new mower.
What to inspect before you buy an engine
Use the 247289330 owner's manual to review safety and service guidance, then inspect these common “make or break” areas:
| Area | What “good” looks like | What pushes you toward replacing the mower |
|---|---|---|
| Deck and blades | Deck is straight; blades stop quickly after disengaging PTO | Deck is cracked, heavily rusted, or blades do not stop promptly |
| Drive system | Smooth engagement; consistent speed | Slipping, whining, or loss of drive when warm |
| Fasteners and mounts | Engine mount bolts and blade hardware stay tight | Stripped threads, broken mounts, repeated loosening |
| Fuel/air | Clean fuel, clean air filter, no debris packed on cooling fins | Stale fuel issues plus heavy overheating damage |
Why it matters
An engine swap can extend the life of a good chassis for years, but it does not fix underlying deck, drive, or safety problems. The manual also emphasizes keeping nuts/bolts tight, maintaining safety interlocks, and clearing debris around the engine to prevent overheating and fire hazards.
Safety notes we follow during engine-related work
- Disconnect the spark plug wire(s) before any repair work.
- Let the muffler and engine cool completely before touching.
- Never bypass the safety interlock system.
- Keep grass and debris cleared from the engine cooling fins and housing.
