Craftsman 917273010 tractor Parts

On Craftsman model 917273010 lawn tractors, the year is typically encoded in the serial number or date code on the ID tag. We use the tractor’s product ID label (not the engine tag) and match the date format shown in the owner's manual to identify the build year.

Where to find the serial number and date code

Look for the product identification label in one of these common spots:

• Under the seat pan (lift the seat)
• On the rear fender pan near the seat
• On the frame rail near the engine
• Near the steering column support

Write down both the model number (917273010) and the serial number exactly as shown.

How to decode the year (most common Craftsman formats)

Craftsman used more than one serial number style over the years. These are the most common patterns we see on riding mowers and tractors:

• 6-digit date code: often reads as MMDDYY (month, day, year)
• 10+ character serial: the year may be embedded, but the position varies by production run
• Engine serial: useful for engine parts, but it does not reliably date the tractor chassis

Quick examples

Code on tag	Typical meaning	Year
072811	July 28, 2011	2011
031506	March 15, 2006	2006

Why it matters

Knowing the correct year helps us match the right diagrams and parts for your 917273010, especially for items that change across production runs such as the pto switch 582107601 or the starter solenoid 532146154.

Tips to avoid a wrong match

• Use the tractor ID tag first; use the engine tag only as a secondary reference.
• If your tag has letters mixed with numbers, copy everything including dashes.
• When ordering, match by model number + serial/date code, not by appearance alone.

Craftsman engines are made by several different manufacturers depending on the specific tractor or mower model and production run. For Craftsman riding equipment like model 917273010, the engine is commonly sourced from major small-engine makers such as Briggs & Stratton, Kohler, or Kawasaki; the sure way to identify yours is by checking the engine ID label and the model’s documentation in the owner's manual.

How to identify who made the engine on your 917273010

Look for the engine’s identification label (usually on the blower housing, valve cover area, or near the starter). Use these details to match the manufacturer:

• Engine brand name on the shroud (Briggs & Stratton, Kohler, Kawasaki)
• Engine model and type code (or spec number)
• Serial number
• Horsepower/cc rating (helps confirm the correct parts list)
• Any emissions label that lists the engine family

What “Craftsman engine” usually means

Craftsman is the equipment brand; the engine is often built by an engine OEM and installed on the tractor during assembly. That is why two Craftsman tractors can use different engines even if they look similar.

Quick comparison: common Craftsman engine suppliers

Engine maker	Typical identifiers on the label	What you’ll use it for
Briggs & Stratton	Model, Type, Code	Tune-up parts, carburetor and ignition matching
Kohler	Model, Spec, Serial	Correct filters, fuel system parts, charging system
Kawasaki	Model, Spec, Serial	Correct air filter, fuel filter, and ignition parts

Why it matters

Engine manufacturer determines the correct maintenance parts (air filter, spark plug, fuel filter) and troubleshooting steps. It also helps when diagnosing no-start or no-crank issues that can involve the ignition key, PTO switch, or starter circuit.

Related parts that can affect starting (on this model)

If the tractor will not crank or the starter only clicks, these parts are commonly involved:

• Solenoid 532146154 (starter solenoid)
• Molded ignition key 532140403 (key and switch engagement)
• Switch.pto.3 582107601 (PTO safety interlock)

For a Craftsman riding lawn tractor like model 917273010, a full engine replacement typically costs about $800 to $2,500 total (engine plus labor). The biggest price drivers are engine brand/horsepower, whether you replace related wear parts, and local shop labor rates; see the 917273010 owner's manual for engine and service details.

Typical cost breakdown

These ranges reflect common riding mower engine swaps (not a tune-up or carburetor repair).

• Engine assembly: $500 to $1,800
• Labor (shop): $300 to $900 (often 4 to 8 hours)
• Fluids and small supplies: $20 to $80
• Optional add-ons: $50 to $400 (battery, belts, pulleys, wiring repairs)

Item	Typical range	Notes
Engine (new)	$500 to $1,800	Varies by horsepower and crankshaft specs
Labor	$300 to $900	Higher if rusted fasteners or wiring issues
Total installed	$800 to $2,500	Most common real-world range

What changes the price the most

• Crankshaft size and length: Must match your pulley and PTO drive setup.
• Electrical system condition: Weak connections can add diagnostic time.
• Drive and deck condition: Worn belts or pulleys can make a new engine feel “weak.”
• Shop minimum charges: Many shops bill a minimum even for straightforward swaps.
• DIY vs. shop install: DIY saves labor but requires safe lifting and correct alignment.

Smart checks before you commit to an engine

In many “needs an engine” cases, the fix is actually fuel, ignition, or starting.

• Confirm the engine turns freely by hand (spark plug removed).
• Check battery cables and starter circuit; a bad starter solenoid can mimic engine failure.
• Verify safety interlocks and PTO switch operation.
• Inspect belts and pulleys for binding.
• If it only clicks or will not crank, follow riding lawn mower engine clicks but doesnt turn over video.

Parts that commonly get replaced during starting or electrical repairs

If your issue is no-crank or intermittent starting, these model-compatible parts are often involved:

• Solenoid 532146154
• Molded ignition key 532140403
• Switch.pto.3 582107601

Why it matters

An engine swap is one of the highest-cost repairs on a riding mower. Verifying the starting, fuel, and safety circuits first helps you avoid replacing an engine when a solenoid, PTO switch, or wiring issue is the real cause.
