Are gas lawn mowers being phased out?
Gas walk-behind mowers like the Craftsman 917379202 are still widely used, but the market is shifting toward battery-electric models as some states and cities restrict new gas-powered outdoor equipment sales and many homeowners prefer lower-noise, lower-maintenance options. Existing gas mowers remain serviceable for years with proper upkeep.
What “phased out” usually means (and what it does not)
Most changes focus on new equipment sales, not taking away equipment you already own. For a rotary lawn mower like the Craftsman 917379202, the practical impact is usually:
- You can keep using your mower as long as it runs safely.
- Parts support often continues for many years after sales slow.
- Local rules may affect where and when gas equipment can be used (noise or emissions ordinances).
- Retail shelf space may shift toward electric, but gas parts and service remain common.
For model-specific operating and safety details, follow the owner's manual.
How to decide whether to keep your gas mower or switch
If your Craftsman mower starts reliably and cuts cleanly, keeping it is often the best value. Consider switching if you want less routine maintenance or you have storage and fuel-handling concerns.
| Factor | Gas mower (like 917379202) | Battery-electric mower |
|---|---|---|
| Maintenance | Oil, spark plug, air filter, fuel care | Blade care, battery care |
| Noise | Typically louder | Typically quieter |
| Runtime | As long as you have fuel | Limited by battery capacity |
| Storage | Fuel stabilizer and winterizing | Battery storage temperature matters |
Maintenance that keeps a gas mower viable longer
Good maintenance matters more as equipment ages. We recommend:
- Use fresh fuel; avoid storing gas from one season to the next.
- Let the engine cool before storing; never store with fuel indoors near ignition sources.
- Keep the blade tight and in good condition; a loose blade can damage the blade adapter.
- Replace worn drive components if self-propel stops pulling (belt, gears, wheels).
- Winterize before long storage (oil in cylinder, new spark plug as needed).
If you need a correct replacement cutting blade for this model, match by fit and length; the blade.22.mul 532406713 is a listed 22-inch mulching blade option.
Why it matters
Regulations and retail trends can change what is easy to buy new, but your day-to-day experience depends on reliability, safety, and parts availability. Keeping your Craftsman 917379202 maintained protects performance and helps avoid costly deck, blade adapter, or drive damage.

Is 2 year old gasoline still good for a lawn mower?
No. In a Craftsman 917379202 rotary lawn mower, 2-year-old gasoline is stale and commonly causes hard starting, rough running, and fuel-system problems. Our recommendation is to drain and dispose of old fuel, then refill with fresh gasoline before troubleshooting anything else (see the owner's manual).
What stale gas can do on this mower
The 917379202 manual lists stale fuel and water in fuel as common “does not start” causes, which is exactly what old gas often turns into during storage.
- Makes the engine hard to start or not start at all
- Causes surging, hesitation, or stalling under load
- Leaves varnish deposits that restrict carburetor passages
- Pulls moisture into the fuel (especially with ethanol blends)
- Creates debris that can clog the fuel cap vent or fuel line
What to do (safe, practical steps)
- Move the mower outdoors and let the engine cool.
- Drain the tank into an approved fuel container.
- Refill with fresh gasoline.
- If it still will not start, follow the “does not start” checks in the owner's manual (air filter, spark plug, control bar position, etc.).
- If drive performance is also poor after storage, clean the drive wheel area as described in the manual; debris buildup can bind the wheels.
Quick decision table
| Fuel age in tank | Typical condition | Best action |
|---|---|---|
| 0 to 30 days | Usually OK | Use it normally |
| 1 to 3 months | Starting to degrade | Use soon; avoid long storage |
| 6+ months | Often stale | Drain and replace |
| 2 years | Stale | Drain, replace, then troubleshoot |
Why it matters
Fresh fuel is the fastest, lowest-cost fix for a no-start on a walk-behind mower. Old gasoline can mimic ignition or carburetor failures, so replacing it first prevents unnecessary parts replacement and saves time.

What is the life expectancy of a gas lawn mower?
A well-maintained gas walk-behind mower like the Craftsman 917379202 typically lasts 8 to 10 years. Regular oil changes, blade care, and end-of-season storage steps make the biggest difference in engine life and drive system wear; follow the 917379202 owner's manual maintenance schedule.
What affects mower lifespan the most
- Oil maintenance: check oil regularly and change it about every 25 hours of operation or at least yearly.
- Clean deck and airflow: grass buildup increases corrosion and can strain the engine.
- Blade condition: a bent or dull blade increases vibration and load.
- Drive system care: keep drive wheels clean so they turn freely.
- Storage habits: storing clean and dry prevents rust and fuel issues.
Maintenance checklist we recommend for the Craftsman 917379202
Use this as a simple baseline; match intervals and procedures to the 917379202 owner's manual.
| Task | Typical interval | Why it helps |
|---|---|---|
| Check engine oil level | Before each use | Prevents running low and engine damage |
| Change engine oil | Every 25 hours or yearly | Reduces internal wear |
| Inspect and clean drive wheels | As needed, especially if self-propel slows | Prevents binding from grass and debris |
| Inspect blade and adapter | Every few mows | Reduces vibration and protects crankshaft |
Parts that commonly wear out first
These are normal wear items on gas rotary mowers; replacing them on time helps the mower reach its full life expectancy.
- Blade (mulching blade): consider the blade.22.mul 532406713 if your blade is damaged or won’t sharpen well.
- Drive belt: replace if self-propel slips or stops; see belt 532157769.
- Blade adapter: replace if the blade won’t stay tight or the mounting surfaces are worn; see lawn mower blade adapter 532421176.
Why it matters
Most “mower failures” are really maintenance issues: old oil, clogged debris, or worn drive parts. Keeping the Craftsman 917379202 tuned, lubricated, and stored correctly reduces expensive engine wear and keeps cutting performance consistent.
