Gas walk-behind mowers like the Craftsman 917378900 are not being phased out everywhere; rules vary by state and city, and most changes focus on limiting sales of new gasoline-powered outdoor power equipment rather than banning ownership or use. For model-specific operating and maintenance guidance, use the 917378900 owner's manual.

• Some areas are adopting restrictions on new gas-powered lawn equipment sales to reduce emissions and noise.
• Most policies do not require you to stop using a mower you already own.
• Many regions still allow gas mowers with no special requirements.
• Battery mowers are gaining market share, so gas models may have fewer new options over time.
• Parts support typically continues for years; routine wear items (blade adapter, belts, wheels, cables) remain serviceable.

1. Keep your mower running efficiently (clean deck, sharp blade, fresh fuel, correct throttle setting).
2. Stock common wear parts you replace periodically.
3. If self-propel stops pulling, check the drive system first; the lawn mower wont move troubleshooting video motion drive failure is a good starting point.

Knowing whether your local area is restricting sales versus use helps you decide whether to maintain your Craftsman mower, buy a backup gas mower, or plan a future switch to battery without rushing a replacement.

If your Craftsman gas walk-behind mower model 917378900 needs a repair that costs more than about half the price of a comparable new mower, replacing the mower is usually the cheaper long-term choice. Smaller fixes (belts, wheels, controls) are typically worth repairing.

• Repair it when the fix is routine maintenance or a single worn part.
• Replace it when the repair is a major drivetrain or engine-level expense.
• Replace it when multiple systems are failing at once (starting, drive, cutting).
• Repair it when the mower deck and engine are solid and you just need common wear parts.

For model-specific maintenance and adjustment guidance, use the 917378900 owner's manual.

These are common, contained repairs that often restore performance quickly:

• Replacing a worn self-propel belt such as the lawn mower ground drive belt, 3/8 x 32-1/2-in 532175436
• Replacing a damaged drive control such as the condrol.driv 583134601
• Replacing a worn drive wheel such as the husqvarna lawn mower drive wheel, 8 x 2-in 532180775
• Fixing cutting issues by replacing a worn blade adapter such as the lawn mower blade adapter 581547901

Major failures can approach the cost of a new mower, especially if labor is involved:

• Engine internal problems (low compression, heavy smoking, knocking)
• Repeated no-start issues after fuel-system and ignition basics are addressed
• Drive system damage that requires multiple major components at once

A walk-behind mower’s value is tied to the engine, deck condition, and drive system. Spending heavily on major failures rarely pays back, but replacing common wear parts can keep your Craftsman mower cutting and driving reliably for seasons.
