Craftsman 917271731 tractor Parts

For Craftsman lawn tractor model 917271731, the tractor is equipped with a 17.5 HP engine (electric start) as shown in the specifications section of the 917271731 owner's manual.

How to confirm the exact engine brand and model on your tractor

The manual confirms horsepower, but the quickest way to identify the exact engine make and model (Briggs & Stratton, Kohler, etc.) is to read the engine ID information on the engine itself.

• Look for the engine ID label on the blower housing, valve cover, or near the starter
• Record the model, type, and code (or serial) from the label
• Match that information when ordering engine parts (filters, spark plug, carburetor parts)
• If the label is missing, check for stamped numbers on the shroud or tag bracket
• Keep the engine ID with your tractor model number for future maintenance

What we know from the model 917271731 documentation

The owner’s manual for this Craftsman front-engine lawn tractor lists these key engine-related specs.

Spec	What to expect on 917271731
Starting system	Electric start
Engine output	17.5 HP
Tractor type	Front-engine lawn tractor

Why it matters

Engine identification prevents wrong-part orders and speeds up tune-ups. Many riding mowers share similar frames and decks, but engine families can use different air filters, fuel filters, spark plugs, and carburetor linkages even when horsepower is the same.

Craftsman engines are made by several manufacturers depending on the specific mower or tractor model. For the Craftsman riding tractor model 917271731, the owner’s documentation identifies it as a 17.5 HP tractor with a low-emission engine; the engine’s brand is typically confirmed by the engine ID label and the parts list in the 917271731 owner’s manual.

How to identify who made the engine on model 917271731

Use these quick checks on your tractor before ordering engine parts:

• Look for the engine ID label on the blower housing, valve cover, or near the starter (it lists the engine maker and model).
• Check the horsepower rating and any emissions label wording (often tied to the engine manufacturer).
• Match the engine model/type code to the engine maker’s format (common formats differ by brand).
• Use the tractor’s parts diagrams and maintenance section to confirm the correct engine family.
• If the label is missing, compare the carburetor, air filter housing, and muffler layout to the manual’s illustrations.

Common engine makers you may see on Craftsman riding tractors

Craftsman has historically used multiple engine suppliers across different product years and series. The most common manufacturers include:

Engine maker	Where you’ll usually see it	What to look for on the label
Briggs & Stratton	Many Craftsman lawn tractors	Model, Type, Code fields
Kohler	Some mid to higher spec tractors	Model and Spec numbers
Kawasaki	Some premium tractors	Model and Spec/Serial format

Why it matters

Engine parts (air filter, spark plug, carburetor parts, starter, fuel system components) are matched to the engine model, not just the Craftsman tractor model number. Confirming the engine maker prevents wrong-part returns and helps troubleshooting go faster.

The Craftsman tractor model 917271731 is typically from the mid-2000s (about 2004 to 2006). For the most accurate confirmation, match your tractor’s product ID tag and any date codes to the identification details shown in the 917271731 owner's manual.

How to confirm the build year on your specific tractor

We recommend using the tractor’s ID information (not just the model number) because the same model can be produced across multiple seasons.

• Locate the product ID tag (commonly under the seat, on the frame rail, or near the engine compartment)
• Write down the model number (917271731) and the serial number
• Look for a date code on the tag or on major components (engine, transaxle)
• Compare the decal set and chassis configuration to the illustrated parts lists in the manual
• If the engine has its own model and code label, use that code to narrow the engine’s production date

What the manual confirms (and what it does not)

The documentation we have for this tractor clearly identifies the model and its assemblies, which helps you match your machine to the correct parts diagrams.

What you can verify	Where to verify it	Example from this model’s manual excerpts
Model number	Manual parts lists and diagrams	“TRACTOR MODEL NUMBER 917.271731”
Major assemblies and part breakdowns	Chassis, steering, mower deck sections	Chassis, steering assembly, mower deck listings
Exact production year	Product ID tag and serial/date codes	Not listed in the parts-list pages

Why it matters

Knowing the correct production window helps you avoid ordering the wrong parts when Craftsman made running changes (belt routing, deck hardware, steering parts, decals) within a model family.

If you are matching mower deck parts, the mower deck section in the manual is also a quick way to confirm you have the same deck configuration before ordering items like the husqvarna lawn tractor mulching blade, 21-in 532134149.

Replacing the engine on a Craftsman front-engine lawn tractor like model 917271731 typically costs $260 to $1,800 installed. The total depends on whether you buy a new or remanufactured engine, how much labor is needed, and whether related drive and electrical parts must be transferred or replaced; use the 917271731 owner's manual to match engine mounting and controls.

What drives the total cost

• Engine price: horsepower class, crankshaft size, and whether it includes muffler, starter, and charging system
• Labor time: riding tractors take longer than walk-behind mowers because of wiring, fuel lines, and belt/pulley transfers
• Parts you may reuse or replace: pulleys, key switch, wiring connectors, throttle/choke cables
• Deck and drive condition: worn belts, idlers, or mandrels add time and parts cost
• Shop rate and turnaround: local labor rates and seasonal demand

Typical cost breakdown (parts and labor)

Cost item	Typical range	What it covers
Replacement engine (part only)	$200 to $1,500	Long block or complete engine, depending on package
Labor	$150 to $600	Removal, installation, setup, and test run
Fluids and small supplies	$20 to $150	Oil, filter, fuel line, clamps, hardware

Checks to make before ordering an engine

These are the fit items that prevent expensive returns and rework.

• Crankshaft diameter, length, and keyway (must match your pulley)
• Engine mounting bolt pattern and base style
• Electrical leads: starter cable, charging lead, kill wire
• Throttle and choke linkage compatibility
• Muffler/exhaust clearance and heat shielding

Why it matters

An engine swap only pays off when the rest of the tractor is solid. If the mower deck has vibration or belt slip, plan to service deck-drive parts at the same time, such as the v-belt 532138255, so the new engine can deliver full power to the blades.
