Do Craftsman mowers use Briggs and Stratton engines?
Yes, many Craftsman mowers use Briggs and Stratton engines, but it depends on the specific mower model and production run. For Craftsman lawn tractor model 917275031, the correct way to confirm the engine manufacturer is to match the engine ID information and parts listing in the 917275031 owner's manual.
Craftsman has used multiple engine suppliers across different mower types (push mowers, riding mowers, and lawn tractors). It is common to find Briggs and Stratton on some models, while others use different engine brands.
Common engine-brand possibilities include:
- Briggs and Stratton
- Kohler
- Tecumseh (older equipment)
- Other OEM-supplied engines depending on the mower line
Use these checks to identify what your tractor has without guessing:
- Look for an engine label on the blower housing or valve cover (often shows brand and displacement)
- Record the engine model, type, and code numbers (or spec number)
- Compare that information to the engine-related sections in the 917275031 owner's manual
- Use the tractor model number 917275031 when selecting parts so the correct engine group is shown
| Where to look | What it tells you | Why it helps |
|---|---|---|
| Engine shroud label | Engine brand and model | Confirms manufacturer quickly |
| Engine code/spec | Exact build configuration | Ensures correct tune-up parts |
| Tractor parts diagrams | Which engine family is installed | Prevents ordering mismatched parts |
Engine brand affects the correct maintenance parts and procedures, including the air filter, spark plug, fuel filter, and carburetor settings. Confirming the engine ID first helps avoid buying the wrong parts for your Craftsman lawn tractor.

Is it worth replacing a lawn mower engine?
Replacing the engine on a Craftsman lawn tractor like model 917275031 is worth it when the tractor’s deck, frame, steering, and transmission are still solid and the total engine swap cost stays well below the cost of a comparable new rider. If the tractor has multiple worn systems, replacement usually makes more sense.
- The mower deck is not rusted through and still cuts evenly.
- The transmission drives smoothly (no slipping, grinding, or loss of power).
- Steering and front axle are tight enough to track straight.
- You can source the correct engine or a compatible replacement and hardware.
- The total cost (engine, belts, blades, labor) is under about half the price of a similar new tractor.
Use this simple comparison to decide where your money goes.
| Option | Typical cost | Time/effort | Best when |
|---|---|---|---|
| Replace engine | Higher parts cost | Moderate to high | Chassis and deck are in great shape |
| Repair existing engine | Lower parts cost | High diagnosis time | Problem is fuel, ignition, or compression related |
| Replace tractor | Highest upfront | Low | Multiple systems are worn or unsafe |
Many “bad engine” symptoms are actually electrical or fuel related. Check these first:
- Battery charge and cable connections
- Fresh fuel and clean fuel flow from the tank
- Spark at the plug and a working ignition key switch
- Safety interlock switches (seat, brake, PTO)
- Air filter condition and choke operation
For step-by-step guidance, use the 917275031 owner’s manual.
Even if you replace the engine, you may still need small parts that affect starting and operation:
- Switch.pto 582107601 (PTO engagement and safety circuit)
- Molded ignition key 532140403 (worn keys can cause intermittent contact)
- Belts, pulleys, and mounting hardware as needed
An engine swap can extend the life of a good Craftsman rider for years, but it only pays off when the rest of the tractor is dependable. If steering, drive, and deck components are already failing, you can end up chasing repairs after the engine is new.

How much does it cost to replace a riding lawn mower engine?
For the Craftsman lawn tractor model 917275031, a typical engine replacement (parts plus labor) runs about $260 to $1,800, with around 5 to 8 labor hours for a riding mower engine swap. Exact cost depends on engine type, shop labor rate, and any extra parts needed.
- Engine price: new, rebuilt, or used engine options vary widely
- Labor rate: local shop rates and minimum charges
- Extra parts: belts, wiring, fuel components, and mounting hardware often add cost
- Root cause: overheating, low oil, or fuel contamination can damage related systems
- Turnaround time: seasonal demand can increase labor costs
| Cost item | Typical range | Notes |
|---|---|---|
| Engine (part) | $200 to $1,500 | Biggest variable; depends on horsepower and brand family |
| Labor | $200 to $700 | Often 5 to 8 hours for riding mowers |
| Misc. parts/fluids | $20 to $200 | Oil, filter, fuel line, clamps, hardware |
Many tractors get quoted for an engine when the real issue is electrical, fuel, or safety interlocks.
- Battery weak or connections corroded
- Starter solenoid or starter circuit issue
- Fuel stale, clogged fuel line, or dirty carburetor
- Safety switch or PTO circuit preventing crank
- Compression loss from a stuck valve (less common, but possible)
If the engine clicks but won’t crank, follow riding lawn mower engine clicks but doesnt turn over video. If it cranks but won’t start, use riding lawn mower engine spins but wont start video.
These are not “engine parts,” but they are commonly disturbed or found worn during the swap:
- Ignition key and switch components
- Fuel tank and fuel tank stem (if leaking or brittle)
- PTO switch (if the deck engagement circuit is failing)
For model 917275031, examples include the switch.pto 582107601 and the husqvarna lawn tractor fuel tank 532151346 when troubleshooting PTO engagement or fuel delivery issues.
A full engine replacement is one of the highest-cost repairs on a riding mower. Confirming the starting, fuel, and safety interlock systems first helps you avoid paying for an engine when a switch, wiring, or fuel issue is the real problem.
For model-specific procedures, torque points, and routing details, use the 917275031 manual.
