What we can confirm for model 917271660

• Engine type: low-emission design (operates differently than older engines)
• Starting system: electric start
• Mower deck size: 42-inch
• Drive system: automatic transmission

Where to find the engine brand and model (fast)

The engine manufacturer (commonly Briggs and Stratton, Kohler, or similar on tractors of this class) is identified on the engine itself and in the documentation.

• Check the engine shroud/valve cover label for the engine model, type, and code
• Look for the emissions label near the muffler or blower housing
• Match those numbers to the tune-up section in the 917271660 owner's manual
• Use the engine model to buy the correct spark plug, air filter, and oil filter

Common engine types you will see on tractors like this

Engine style	What it means	What you will notice
Single-cylinder gasoline	One-cylinder mower engine	More vibration, simpler maintenance
Low-emission design	Newer emissions-compliant carb/fuel setup	Can be more sensitive to stale fuel

Why it matters

The engine make and model determines the correct maintenance parts and settings (spark plug type/gap, air filter style, oil capacity, and carburetor adjustments). Using the wrong tune-up parts can cause hard starting, surging, or poor power under load.

Replacing the engine on a Craftsman lawn tractor model 917271660 typically costs $800 to $2,500 total (engine plus labor). The final price depends on engine type, whether you reuse pulleys and wiring, and how much shop time is needed for setup and safety checks.

What makes the price go up or down

• Engine cost: Most replacement riding mower engines fall in the $500 to $1,800 range.
• Labor time: Commonly 3 to 8 hours, depending on rusted fasteners, wiring condition, and alignment.
• Extra parts: Belts, pulleys, keys, and hardware often get replaced during the swap.
• Deck and drive condition: If the tractor also has a worn drive belt or deck issues, the shop may recommend addressing those at the same time.
• DIY vs shop: DIY saves labor but still requires careful setup and testing.

Typical cost breakdown

Cost item	Typical range	Notes
Replacement engine	$500 to $1,800	Varies by horsepower, crankshaft size, and brand compatibility
Labor	$300 to $1,200	Based on 3 to 8 hours shop time
Misc. parts and supplies	$25 to $200	Fuel line, clamps, oil, filter, hardware
Total installed	$800 to $2,500	Most common real-world range

Smart checks before you buy an engine

We recommend confirming the tractor is worth the investment and that the “no-run” problem is truly engine-related.

• Verify the engine turns freely (not seized)
• Check battery and starting circuit first (clicking or no-crank can be electrical)
• Confirm the key and ignition switch are working (a lost or damaged key is common)
• Inspect belts and pulleys for binding that can overload the engine
• Review the maintenance and troubleshooting sections in the 917271660 owner's manual

If you need a replacement key during diagnosis, the molded ignition key 532140403 is a common wear item for this tractor.

Why it matters

An engine replacement can cost more than the tractor’s resale value, but it can still be the best choice when the deck, transaxle, and chassis are in good shape and you want reliable mowing for years.

For Craftsman lawn tractor model 917271660, the engine manufacturer shown in the tractor documentation is Briggs & Stratton. “547cc IntelliPower” is a marketing label used on other tractor lines; it is not the engine description used for this Craftsman model.

What the 917271660 documentation shows

In the engine section of the tractor parts breakdown, the engine is identified as a Briggs & Stratton engine, and the engine breakdown pages are labeled for a Briggs & Stratton engine.

• Check the engine pages in the tractor parts breakdown for the maker name
• Use the engine’s model and type from the engine ID tag when ordering engine-specific parts
• Match tune-up parts by engine family (air filter, spark plug, fuel filter) rather than by deck size
• If your tractor has had an engine swap, the engine ID tag is the deciding reference

IntelliPower vs this Craftsman tractor (how to tell them apart)

Item to compare	“547cc IntelliPower” engines	Craftsman 917271660
How it’s described	Marketing name tied to certain newer tractors	Identified by Briggs & Stratton maker and engine breakdown in documentation
Best way to identify	Engine label and model/type on the engine	Engine ID tag plus the tractor’s engine breakdown
Best way to buy parts	Use engine model/type, not the marketing name	Use engine model/type, not a cc claim

Why it matters

Engine parts (carburetor, ignition parts, gaskets, filters) must match the exact engine model and type. Using a “547cc IntelliPower” description on a Craftsman 917271660 can lead to ordering the wrong parts.
