Craftsman 917271060 42" 15.5-hp automatic lawn tractor Parts

For the Craftsman 917271060 (42 in, 15.5 HP automatic) riding lawn tractor, a full engine replacement typically costs $260 to $1,800 installed, depending on the engine, labor rates, and any extra parts needed; plan on about 6 labor hours for a riding mower engine swap.

What drives the total price

Engine replacement cost is mostly parts plus labor, with a few common add-ons that can change the final bill.

• Engine price (new or remanufactured) is the biggest variable
• Labor rate and shop minimums vary by region
• Extra parts often needed: belts, pulleys, wiring repairs, fuel line, clamps
• Deck and drive condition can add time if components are seized or worn
• Pickup and delivery fees (if you do not transport the tractor)

Typical cost breakdown (installed)

Cost item	Typical range	Notes
Engine (part)	$200 to $1,400	Varies by brand, HP, and crankshaft specs
Labor	$200 to $600	Often around 6 hours total
Misc. parts and shop supplies	$20 to $200	Hardware, fuel line, filters, clamps
Estimated total	$260 to $1,800	Most jobs land in the middle of the range

Before you replace the engine, check these common “not an engine” issues

We see many tractors that will not start or will not drive due to safety interlocks, wiring, or belt problems, not a failed engine.

• Verify the operator presence and interlock system works correctly (seat switch, brake switch, PTO switch)
• Inspect wiring and connectors for looseness or damage
• If the tractor has loss of drive, check the freewheel control position and the ground drive belt condition
• If the mower deck is the issue (blades not turning), inspect the deck drive belt and mandrels
• Review the safety and troubleshooting steps in the 917271060 owner's manual

Why it matters

An engine swap is one of the highest-cost repairs on a riding mower. Confirming the problem first helps you avoid paying for an engine when a belt, switch, or wiring repair would restore operation.

On the Craftsman riding mower model 917271060, the model and serial number are typically found on the tractor frame under the seat (or on the underside of the seat). Use that exact model number to match the correct parts list and the correct 917271060 owner's manual.

Where to find the model and serial number

Check these common locations on Craftsman front-engine lawn tractors:

• On the frame under the seat (lift the seat up)
• On the underside of the seat pan
• Near the rear fender or seat support area (on a sticker or metal tag)
• On the frame rail close to the transmission area

How to use the number to look up parts

Once you find the tag, copy the numbers exactly (including any dots or dashes on older tags) and use them to identify the right diagrams and replacement parts.

• Write down the model number and serial number
• Match the model number to the tractor family (for example, 917.271060 is commonly shown as 917271060)
• Use the serial number to confirm production range when multiple versions exist
• Keep the tag info with your maintenance records for belts, blades, and tune-up parts

Quick guide: model number vs. serial number

What you see on the tag	What it’s used for	Example for this tractor
Model number	Identifies the exact tractor design and parts breakdown	917271060 (often printed as 917.271060)
Serial number	Identifies the build sequence and production run	Varies by unit

Why it matters

Using the exact model number prevents ordering the wrong deck parts, drive components, or electrical items. Even tractors with the same 42-inch deck and 15.5 HP rating can use different belts, blades, or mandrel assemblies.

Craftsman uses engines from multiple manufacturers across its riding mower lineup. For Craftsman model 917271060, the sure way to identify the engine brand is to read the engine identification label on the engine itself; use that brand plus the engine model/type/code to match engine-specific parts. See the 917271060 owner's manual for the tractor’s operating and maintenance specifications.

How to identify the engine brand on a Craftsman 917271060

Check the engine tag, not the tractor hood decal. On most 15.5 HP lawn tractor engines, the ID label is easy to spot.

• Look for a label on the blower housing, valve cover, or near the starter
• Write down the engine brand (commonly Briggs & Stratton, Kohler, or Kawasaki)
• Record the engine model, type/spec, and code/serial numbers
• Use the tractor frame tag to confirm the tractor model is 917271060
• Use engine numbers for tune-up parts (air filter, fuel filter, spark plug, carburetor parts)

What the 917271060 manual tells you (and what it does not)

The manual is designed for operation and maintenance; it lists service specs you can use regardless of engine brand.

Item (manual spec)	Typical use
Fuel type	Confirms the correct gasoline grade to run
Oil viscosity by temperature	Helps prevent hard starting and engine wear
Spark plug type and gap	Helps restore smooth starting and running

Why it matters

Tractor parts (deck, chassis, drive) match the 917271060 platform, but many engine parts only match when you use the engine brand and engine ID numbers. That prevents ordering the wrong filter, ignition part, or carburetor component.

Examples of tractor parts that match the 917271060 platform

These are tractor components (not engine-internal parts) that are commonly replaced:

• Ignition harness 532179722 (wiring harness for the ignition circuit)
• Molded ignition key 532140403 (key used to operate the ignition switch)
• Lawn tractor ground drive belt, 1/2 x 82-in 532140294 (belt that drives the transmission)

For Craftsman model 917271060 (42-inch, 15.5 HP automatic lawn tractor), the owner’s manual identifies it as a 15.5 HP tractor but does not list a specific engine brand or model in the excerpts we have. Use the tractor’s engine ID label and the 917271060 owner's manual to match the correct tune-up and repair parts.

How to identify the exact engine on your 917271060

Check the engine itself, not the mower deck or tractor frame. Most riding mower engines have an ID tag (often on the blower housing, valve cover area, or near the starter).

• Look for engine model, type, and code (or a spec number) on the label
• Write the numbers down exactly; letters matter
• Use the engine ID to choose the right spark plug, air filter, oil filter, and drive belt parts
• If the label is dirty, wipe it and use a flashlight to read stamped characters
• Keep the engine ID with your maintenance records for faster parts lookup later

What we can confirm from the manual (model 917271060)

The manual provides key operating and maintenance specs for this tractor setup.

Spec (from manual)	Value
Horsepower class	15.5 HP
Fuel capacity	1.25 gallons
Fuel type	Unleaded regular
Spark plug	Champion RC12YC (gap 0.030 in.)
Oil capacity	4.0 pints with filter; 3.5 pints without filter

Why it matters

Craftsman tractors in the 917 series can be built with different engine families over time. Using the engine ID prevents ordering the wrong ignition parts or maintenance items, and it helps ensure correct oil and tune-up specifications.

Related parts customers commonly replace

These are tractor parts (not engine-brand specific) that often come up during maintenance and mowing performance issues:

Craftsman model 917271060 is a 42-inch, 15.5-hp automatic lawn tractor; this model number identifies a specific tractor configuration, but the exact build year is determined by the product identification label (serial/date code) on the tractor, not by the parts list alone. Use the 917271060 owner's manual to locate the ID label and decode the date.

How to find the build date on your tractor

Look for the product identification label in the common locations below (the manual shows the exact spot for this model):

• Under the seat pan or on the seat bracket area
• On the rear fender pan (near the seat)
• On the frame rail, typically left side
• Under the hood near the dash tower
• Near the transaxle area on the frame

What to write down (so you get the right year)

Record these items exactly as shown on the label:

• Model number: 917271060
• Serial number (sometimes called product number)
• Any date code or manufacture code
• Engine model information (this tractor commonly uses a Kohler CV15S-series engine)

Quick guide: model number vs. serial number

Label item	What it tells you	Why it matters
Model number (917271060)	The tractor design and parts family	Ensures correct parts diagrams and assemblies
Serial number / date code	The production run and build date	Pins down the exact year
