Do Craftsman mowers use Briggs and Stratton engines?
Some Craftsman mowers use Briggs and Stratton engines, but not all. For the Craftsman lawn tractor model 917271110, the engine family varies by production configuration, so the most reliable way to confirm what your tractor has is to match the engine identification on the unit to the specs in the 917271110 owner's manual.
How to confirm the engine on your 917271110
Use the tractor itself to verify the engine brand and model; that is what parts and tune-up specs are based on.
- Lift the hood and look for an engine label on the blower housing or valve cover.
- Write down the engine model, type, and code (common on Briggs engines).
- Compare those numbers to the engine section in the 917271110 owner's manual.
- If the label is missing, check for a stamped ID near the starter or muffler area.
- Use the engine ID (not just the tractor model) when ordering ignition, carburetor, and gasket parts.
What the manual tells you (model-level specs)
The 917271110 manual lists tractor-level operating and maintenance specs that apply regardless of engine brand, such as fuel type, oil viscosity by temperature, and tire pressure.
| Item | Spec for 917271110 |
|---|---|
| Fuel | Unleaded regular; 1.25 gallon capacity |
| Oil type | SAE 30 above 32°F; SAE 10W-30 below 32°F |
| Tire pressure | Front 14 PSI; rear 10 PSI |
| Blade bolt torque | 27 to 35 ft-lbs |
Why it matters
Engine brand and model determine the correct tune-up parts (spark plug, air filter, fuel filter) and service procedures. Using the tractor model alone can lead to the wrong engine parts, even when the deck and drive parts are correct.

What drives the total cost

- Labor rate (common shop rates vary widely by region)
- Extra parts discovered during removal (belts, pulleys, wiring, mounts)
- Tune-up items (spark plug, air filter, fuel filter, oil)
- Deck and drive condition (a worn belt or seized pulley can add time)

Parts that commonly get replaced at the same time

Why it matters
A riding mower engine swap is a major repair, so it only makes sense if the rest of the Craftsman 917271110 is in good shape (deck, transmission, steering, and frame). The manual also emphasizes safe service practices, including never making adjustments with the engine running and using extra caution around sharp mower blades.
