Craftsman 917272421 lawn tractor Parts

For the Craftsman lawn tractor model 917272421, the engine manufacturer depends on the specific tractor configuration; this model’s 917272421 owner's manual lists a Kohler engine (Kohler model CV492-27506) in the engine breakdown, so Kohler is the maker for this version.

Even within the same Craftsman model family, the most reliable way to confirm is to match the engine ID on the tractor to the manual and parts list.

• Check the engine ID label on the engine shroud or valve cover (it typically lists the brand and model).
• Compare that engine model to the engine listing in the manual’s engine breakdown.
• Use the tractor model number 917272421 when ordering parts to avoid mismatches.
• If the tractor has been repowered, use the engine’s model and spec numbers for engine parts.

The documentation for this model points to Kohler as the engine supplier.

The engine maker determines the correct tune-up and repair parts (spark plug, air filter, fuel system parts, muffler, and gaskets). For example, this model’s engine parts list includes an exhaust muffler; if you’re replacing it, match the tractor parts list and use an exact-fit part such as the exhaust muffler 532159420 when it applies to your configuration.

The Craftsman lawn tractor model 917272421 is an 18.0 HP electric-start riding lawn tractor with a 42-inch mower deck, as shown in the 917272421 owner's manual.

Even within the same tractor model, the engine manufacturer and engine model code are best confirmed from the engine ID label on the engine itself.

• Lift the hood and look for the engine label on the blower housing, valve cover, or near the starter
• Write down the engine model, type, and code (or spec number)
• Match that information to the engine parts list in the manual
• Use the engine model code when ordering tune-up parts (spark plug, air filter, fuel filter)
• If the label is missing, check for stamped numbers on the engine shroud or tag near the muffler

The manual identifies the tractor configuration and power rating, which helps narrow engine families used on this platform.

The tractor model number (917272421) helps you find chassis and deck parts, but the engine model code is what ensures you get the correct ignition, fuel, and air-intake maintenance parts for reliable starting and smooth mowing.

Yes. On a Craftsman lawn tractor model 917272421, replacing the engine is worth it when the deck, steering, drive system, and wiring are in solid condition and the total swap cost stays well below the price of a comparable replacement tractor.

• The mower deck is structurally sound (no cracks or rust-through)
• The tractor drives strongly with no belt slip or weak pull
• Safety interlocks work (seat switch, brake start interlock, PTO interlock)
• You can source a correct replacement engine or compatible short block
• You can handle the labor, tools, and setup time

A bad engine is only one part of the total value. Check these common deal-breakers first:

• Deck and blade system: bent blades, worn mandrels, heavy grass buildup around mandrels and vent holes
• Belts and pulleys: cracking, glazing, or squeal under load
• Safety system behavior: engine starts only with brake depressed and PTO disengaged; engine shuts off if the operator leaves the seat under the conditions described in the manual
• Maintenance condition: dirty air filter, overheating from debris on hot engine or exhaust parts

An engine swap is a major repair; the tractor must remain safe afterward. Our guidance aligns with the safety and maintenance practices in the 917272421 owner's manual, including checking safety devices regularly and keeping debris off hot engine and muffler areas.

The Craftsman lawn tractor model 917272421 is shown in the manual with a Kohler engine identified as model CV492-27506 in the engine breakdown. To confirm the exact engine on your tractor, match that model number to the engine ID tag and use it when ordering engine-only parts.

Use the engine’s ID label because it includes the full model and spec information Kohler uses for parts lookups.

• Locate the engine ID tag on the blower housing, valve cover area, or engine shroud
• Wipe off grass and oil so the numbers are readable
• Record the full engine model (example shown: CV492-27506) plus any spec and serial numbers
• Use the engine model for tune-up parts like air filters, spark plugs, and carburetor items
• Use the tractor model (917272421) for chassis and mower deck parts

Using the engine model number prevents wrong-part returns, especially for Kohler-specific items where small spec differences change the correct gasket, filter, or ignition component.

These are tractor-matched parts commonly replaced during deck or chassis service:

• Craftsman lawn tractor blade drive belt, 5/8 x 97-2/5-in 532174883
• Husqvarna lawn tractor mulching blade, 21-in 532134149
• Switch.pto 582107601
