Craftsman 917274640 lawn tractor Parts

Yes, Craftsman does use Kohler engines on some riding mower and lawn tractor models, but it depends on the specific tractor. For the Craftsman lawn tractor model 917274640, the engine make is identified in the 917274640 owner's manual, and that is the best way to confirm what your tractor was built with.

Use these quick checks on your 917274640:

• Check the engine shroud or valve cover for a brand badge (Briggs & Stratton, Kohler, Kawasaki).
• Look for the engine model and type numbers on the engine label (often near the starter, blower housing, or valve cover).
• Match the engine information to the specifications section in the 917274640 owner's manual.
• Use the tractor model number (917274640) when ordering tune-up and maintenance parts.
• If the tractor cranks slowly or only clicks, test the battery and starting circuit before assuming an engine issue.

Craftsman riding equipment has commonly been sold with engines from multiple manufacturers. Here is what that means in practical terms.

Engine brand determines the correct maintenance parts (air filter, spark plug, oil filter) and the right troubleshooting steps for no-start or hard-start problems. Using the engine label plus the tractor model keeps you from ordering the wrong parts.

If your tractor is not starting normally, these guides walk through the most common causes:

• Riding lawn mower engine clicks but doesnt turn over video

Yes, replacing the engine on your Craftsman lawn tractor model 917274640 is worth it when the tractor’s deck, chassis, steering, and transmission are still solid and you want several more seasons of reliable mowing. It is usually not worth it when the tractor has major deck rust, repeated drivetrain issues, or multiple worn safety and control systems.

• The mower deck is structurally sound (no cracks, severe rust-through, or bent spindles).
• The tractor still cuts well when blades and belts are in good shape.
• Steering, brakes, and safety interlocks operate correctly.
• You can do the work safely (fuel handling, lifting, wiring, torqueing fasteners).
• The total repair cost stays well below the cost of replacing the tractor.

Use this simple comparison to decide where your money goes.

Even when the engine is the main issue, we often see these related items matter for starting, running, and cutting performance:

• Ignition switch 532193350 if the key switch is intermittent
• Solenoid with brass plunger 532146154 if you get a click but no crank
• Molded ignition key 532140403 if the key is worn or damaged
• Blade drive belt 532174883 if the deck drive slips after the engine runs

An engine swap only pays off when the rest of the tractor is safe and serviceable. Your manual emphasizes keeping hardware tight, maintaining safety devices, and avoiding adjustments with the engine running; those basics protect you and prevent repeat failures after a major repair. Use the maintenance and safety sections in the owner's manual to evaluate the tractor before you invest in an engine.

The model number is 917274640. On this Craftsman riding lawn tractor, the owner’s manual identifies it as Model No. 917.274640 (often written without the dot as 917274640). For confirmation, match the number on your tractor’s model label to the owner's manual.

We typically see the model label in one of these spots on Craftsman riding mowers:

• Under the seat on the fender pan
• On the frame rail near the engine
• Near the rear hitch plate or drawbar area
• Under the hood area on the chassis
• On a sticker or metal tag with model and serial information

Craftsman model numbers are sometimes printed with punctuation in manuals but searched without it.

We use the exact model number to match the correct parts diagrams and part numbers for your mower deck, chassis, electrical system, and drive components. Even a single digit difference can point to a different deck size or wiring setup.

Before ordering, confirm these details match your tractor:

• Model number: 917274640
• Deck size (commonly 42-inch on this model family)
• Blade type you need (mulching vs. high-lift)

If you are replacing blades for the 42-inch deck, common options listed for this model include the lawn tractor 42-in deck high-lift blade 532138971 and the husqvarna lawn tractor mulching blade, 21-in 532134149.

Replacing the engine on a Craftsman riding lawn tractor like model 917274640 typically costs about $800 to $2,500 total (engine plus labor), depending on engine type, whether you reuse pulleys and wiring, and local labor rates. Engine replacement is a major repair, so we recommend confirming specs and procedures in the owner's manual.

Here are the biggest factors that change the price:

• Engine type and horsepower (single-cylinder vs. V-twin, vertical shaft)
• New vs. remanufactured vs. used engine (used is cheaper, but higher risk)
• Parts you replace at the same time (belts, pulleys, electrical parts)
• Labor time (shop rates vary; engine swaps often take several hours)
• Extra repairs discovered during removal (rusted fasteners, worn wiring, damaged mounts)

These ranges fit most front-engine riding mowers and lawn tractors.

If the tractor had starting or blade-drive issues before the engine failed, these parts are often worth checking while everything is accessible:

• Solenoid with brass plunger 532146154 (starter solenoid)
• Lawn tractor ignition switch 532193350 (key switch)
• Ignition harness 583209001 (wiring harness)
• Craftsman lawn tractor blade drive belt, 5/8 x 97-2/5-in 532174883 (deck belt)

An engine replacement only pays off when the rest of the tractor is in solid shape. If the deck, mandrels, steering, or transmission also need major work, the total repair cost can climb quickly, even if the engine price looks reasonable.
