Craftsman 917250510 lawn tractor Parts

For Craftsman lawn tractor model 917250510, the owner’s manual lists the engine model number as MV20S-57529. You can confirm the exact engine model on the engine blower housing and use that number when ordering engine-specific parts. See the 917250510 owner's manual.

How to identify the engine on your tractor

We recommend using the engine’s model number (not just horsepower) because many Craftsman tractors share similar frames but use different engines.

• Lift the seat and locate the tractor model plate to confirm 917250510.
• Find the engine model number on the blower housing (engine shroud).
• Write down the full engine model number exactly as shown: MV20S-57529.
• Use the engine model number when ordering engine parts (filters, carburetor parts, starter parts).
• Use the tractor model number when ordering chassis and deck parts (belts, steering, wheels).

Tractor model number vs. engine model number (quick guide)

What you’re looking up	Use this number	Where to find it
Tractor, deck, steering, wheels	917250510	Model plate under the seat
Engine-specific parts and specs	MV20S-57529	Blower housing on the engine

Why it matters

Using the correct engine model number prevents wrong-part issues, especially for tune-up items and fuel system parts. It also speeds up troubleshooting when the engine won’t start, clicks, or spins without firing.

Yes. Craftsman uses Kohler engines on some lawn tractors, and the Craftsman lawn tractor model 917250510 specifically lists a Kohler MV20S (type 57529) engine in the repair parts section of the 917250510 owner's manual.

What this means for parts and service

Knowing the engine brand and model helps you buy the right tune-up and engine parts (and avoid ordering tractor-frame parts by mistake).

Common engine-related items you may need to match to the Kohler MV20S include:

• Air filter and pre-filter
• Spark plugs
• Oil filter
• Fuel line and fuel filter
• Starter and solenoid components

Quick ID checklist before ordering

Use these checks to confirm you are shopping the correct engine family:

• Verify the tractor model number is 917250510
• Look for the engine label showing MV20S and 57529
• Match the part description to the engine section (not the mower deck section)
• Compare mounting style and connector type (starter, charging lead, kill wire)
• If you are replacing fuel system parts, confirm tank and line routing first

Parts on this model page that relate to the engine

These are tractor parts commonly involved in engine operation on model 917250510:

Part	What it affects	When to consider it
Fuel tank assembly 532151346	Fuel supply	Cracks, leaks, contaminated fuel, broken fittings
Switch 582107601	PTO engagement (electric clutch control)	Blades will not engage, intermittent PTO
Molded ignition key 532140403	Starting/security	Lost key, worn key causing poor contact

Why it matters

Kohler engines have model and type numbers that determine the correct carburetor parts, gaskets, oil filter adapter pieces, and other engine-specific components. Using the exact MV20S-57529 identification keeps repairs accurate and reduces repeat failures.

Replacing the engine on a Craftsman riding lawn tractor like model 917250510 typically costs about $260 to $1,800 installed, depending on the engine type, whether it’s a direct-fit replacement, and local labor rates. Plan on around 6 hours of labor for a full engine swap.

What drives the total cost

• Engine price: new, rebuilt, or used engines vary widely
• Fitment: direct bolt-in replacements cost less than custom-fit swaps
• Labor time: engine removal, wiring, throttle/choke linkage, and belt/pulley transfer
• Extra parts: fuel line, filters, battery, belts, or pulleys often get replaced at the same time
• Shop rates: hourly labor rates vary by region and season

Typical cost breakdown

Cost item	Typical range	Notes
Engine (part only)	$200 to $1,400	Biggest variable; depends on brand/HP and availability
Labor	$200 to $600	Often 4 to 8 hours total for a riding mower
Misc. parts/fluids	$20 to $200	Oil, fuel filter, clamps, belts, hardware

Smart checks before you buy an engine

We recommend ruling out common “no start” or “no crank” problems first, because they can look like engine failure.

• Confirm the battery is charged and cables are clean/tight
• Check safety interlocks (seat switch, brake/clutch switch, PTO switch)
• Verify the starter engages and the engine turns freely
• Inspect belts and pulleys for binding
• Make sure fuel is fresh and the air filter is not plugged

Parts that commonly get replaced during an engine swap

If your tractor has starting or PTO engagement issues, these model-matched parts are often involved:

• Pto switch 582107601 (controls blade engagement circuit)
• Molded ignition key 532140403 (worn keys can cause intermittent contact)
• Fuel tank assembly 532151346 (if the tank is leaking or contaminated)

Why it matters

A correct engine replacement restores power and reliability, but the best value comes from confirming the real failure first. Many “dead engine” symptoms are caused by electrical interlocks, fuel issues, or belt drag, not the engine itself.

For model-specific maintenance and adjustment procedures, use the 917250510 owner's manual.

The Craftsman lawn tractor model 917250510 does not have a single “model-year” published in the parts manual; this model number is used to identify the correct parts and diagrams, while the serial number/date code on the product ID label identifies when your specific tractor was built. Use the 917250510 owner's manual to locate the ID label and match assemblies.

How to find the build date on the tractor

On Craftsman riding mowers and tractors, the build date is tied to the product identification label, not the parts list pages.

• Look for the product ID label under the seat, on the frame rail, or near the rear fender pan
• Record the serial number exactly as shown (include letters and dashes)
• Record any engine model and type listed on the engine tag (helps confirm the era)
• Compare your tractor’s configuration to the manual’s sections (chassis, ground drive, decals)
• Use the serial/date code to determine the production date range for your specific unit

What the model number tells you (and what it does not)

The model number is the key for ordering correct replacement parts; the serial/date code is what pins down the manufacturing date.

Identifier	Where you find it	What it’s used for
Model number (917250510)	Product ID label	Selecting correct diagrams and parts lists
Serial number/date code	Product ID label	Determining the build date of your tractor
Engine model/type	Engine shroud tag	Confirming engine family for tune-up parts

Why it matters

Craftsman made running changes within similar tractor platforms; using the serial/date code prevents ordering the wrong belt routing parts, switches, or steering components even when the model number matches.

If you are troubleshooting electrical start or safety circuit issues while identifying the tractor, follow how to check the safety interlock circuits on a zero turn lawn tractor.
