Craftsman 917280350 tractor Parts

To identify your Craftsman riding mower, match the model number on the product identification label to your paperwork and parts listings. For this tractor, the model number is 917280350; it also appears as 917.28035 in the 917280350 owner's manual.

On most Craftsman front-engine riding mowers, the identification label is located under the seat area. Use these quick checks:

• Park on a level surface, set the parking brake, and remove the key
• Flip the seat forward (or look under the seat pan) for the product identification label
• Write down the model number and serial number exactly as shown
• Look for punctuation variations (for example, 917280350 vs 917.28035) and record both
• Use the model number to pull the correct parts diagrams and the correct manual

Craftsman model numbers are sometimes printed with a dot in the middle on manuals and decals. These typically refer to the same tractor family.

Using the exact model number prevents ordering the wrong belt, deck, or electrical parts. For example, the correct deck and drive system routing and adjustments are model-specific in the manual, and parts like a starter solenoid or drive belt can vary by series.

Yes; replacing the engine on your Craftsman lawn tractor model 917280350 is worth it when the tractor is otherwise in good condition and the total engine job costs less than about 50% of the tractor’s current value. If multiple major systems are worn, replacement makes more sense.

• Price the full job: engine, labor, fluids, and tune-up parts.
• Compare that total to the tractor’s current value; over ~50% means replace the tractor.
• Confirm the deck and transaxle operate smoothly (no binding, slipping, or loud mechanical noise).
• Rule out safety shutoff problems that mimic engine failure (seat switch, brake/parking brake logic, reverse operation system).
• Check for deck drag that overloads the engine (packed grass, frozen idlers, frozen mandrels).

Use the troubleshooting and safety sections in the 917280350 owner’s manual to verify the engine is truly failing and not being shut down by an interlock or overloaded by the mower deck.

• True engine failure signs: low compression, heavy smoke, knocking, metal in oil.
• Starting issues: weak battery connections, bad cables, or a failing solenoid.
• Deck load issues: obstruction in clutch mechanism, worn belt, frozen idler pulley, frozen blade mandrel.

• No crank or clicking: lawn tractor starter solenoid 582042802
• Blades will not rotate or deck binds: lawn tractor drive belt 532138255

An engine swap is one of the biggest repairs on a riding mower; confirming the real cause prevents spending engine money on a problem that is actually a safety shutoff or a seized deck component.

The Craftsman riding lawn tractor model 917280350 is equipped with a 17.5 HP (as rated by the engine manufacturer) gasoline engine and electric start. Craftsman used different engine manufacturers across tractor models; the exact engine make and model for your unit is identified on the engine label and in the 917280350 owner's manual.

The operator documentation for this tractor calls out these engine-related details:

• 17.5 HP rating (engine-manufacturer rated)
• Electric start
• Operate the engine at full throttle (fast) for best mowing performance
• Use the throttle correctly before stopping to reduce backfiring
• Engine warm-up time increases in colder temperatures

To get the precise engine type (manufacturer plus model/type code), check the engine’s ID information:

• Look for a model/type/code label on the blower housing or engine shroud
• Check near the starter area for an engine ID sticker
• Look for an emissions label that lists engine family information
• Record the numbers exactly; use them when ordering engine-specific parts

The tractor model number gets you the right Craftsman chassis and mower deck parts, but the engine ID is what ensures tune-up and fuel-system parts fit the engine that’s actually installed.
