Craftsman 917370840 lawn mower Parts

Gas walk-behind mowers like the Craftsman 917370840 are not being phased out everywhere at once, but the market is shifting toward battery-electric models as some states and local areas restrict new sales of certain gas-powered outdoor equipment. Your mower remains serviceable and supportable with routine maintenance and replacement parts; use the 917370840 owner's manual for safe operation and upkeep.

Most changes focus on new equipment sales, not taking existing gas mowers out of service.

• Some regions restrict or plan to restrict sales of certain new gas-powered lawn equipment
• Existing gas mowers can typically still be used and maintained
• Retailers may stock fewer gas models over time as demand shifts
• Commercial and heavy-duty use cases often keep gas options available longer
• Parts availability is driven by model demand and supplier production, not just regulations

A well-maintained gas mower cuts cleaner, starts easier, and avoids premature engine wear.

• Clean the underside of the deck after each use (scrape off grass buildup)
• Clean under the drive cover at least twice per season
• Replace the spark plug at the start of each mowing season or every 100 hours
• Inspect safety and wear items (grass catcher components, deflectors, cables)
• Stop and inspect the mower if you strike an object; repair before restarting

If you plan to keep the Craftsman 917370840 for years, these are typical wear items to watch.

Even if electric mowers become more common, keeping your gas mower maintained protects cut quality and reduces downtime. It also helps you avoid damage from overheating caused by grass and debris buildup.
