Are gas lawn mowers being phased out?
Gas walk-behind mowers like the Craftsman 917372270 are not being phased out everywhere at once; the shift is happening gradually as some states and cities restrict new sales of certain gas-powered outdoor equipment, while many areas still allow gas mowers and support parts and service.
What to expect (practical reality)
Even where new gas mower sales are limited, owners typically can keep using and maintaining existing mowers. For the 917372270, routine maintenance and safe operation guidance in the Craftsman 917372270 owner's manual helps you keep the mower reliable for years.
- Existing gas mowers are commonly allowed to be used and repaired.
- Restrictions usually focus on new equipment sales, not ownership.
- Parts support often continues long after a model is discontinued.
- Electric options are growing because they are quieter and lower maintenance.
- Gas mowers remain common for tougher grass, larger yards, and long run times.
How to keep your gas mower viable long-term
A mower that starts easily and runs smoothly is easier to keep in service, regardless of market trends.
- Follow the service schedule for oil changes, blade care, and spark plug replacement.
- Use fresh fuel and avoid storing old gasoline from season to season.
- Keep the deck clean to prevent corrosion and heavy buildup.
- If you hit an object or the mower vibrates excessively, stop and inspect before mowing again.
- Replace wear items promptly, especially cutting components.
Common maintenance items for this model
| Maintenance need | What you do | Example part for 917372270 |
|---|---|---|
| Poor cut quality or tearing grass | Sharpen or replace the blade | Blade 532406713 |
| Hard starting after storage | Refresh fuel, inspect carburetor components | (Fuel system parts vary by engine) |
| Excess vibration | Inspect blade and mounting hardware | Blade plus fasteners as needed |
Why it matters
If your area tightens rules on new gas mower sales, the best way to protect your investment is to keep the Craftsman 917372270 safe, well-maintained, and ready to run. Good maintenance also reduces vibration, improves cut quality, and helps prevent avoidable engine and deck damage.

What model number is the Craftsman 917372270?
The model number is 917372270. On Craftsman walk-behind mowers, the model number is the primary identifier we use to match the correct repair parts list, diagrams, and service information for your exact mower.
Where to find the model number on the mower
Most Craftsman walk-behind mowers list the model number on a product label or decal. Check these common spots:
- Rear of the mower deck near the discharge opening
- Top of the deck near the engine mounting area
- Back panel behind the bagger (if equipped)
- Handle support area near the height adjuster brackets
For model-specific label locations and parts diagrams, use the 917372270 owner's manual.
Why the model number matters for parts
Many walk-behind mowers look similar but use different blades, drive parts, and hardware. Using 917372270 helps ensure you get the right fit for items such as:
- Blade and blade mounting hardware
- Drive control and wheel adjuster parts
- Belts, bushings, and bearings
- Engine-related service parts (carburetor and starter components)
Example: a common model-matched part
If you are replacing the cutting blade on this mower, match by model number and deck size. A commonly listed blade for this model is the blade 532406713.
| What you are doing | What to match | What can go wrong if mismatched |
|---|---|---|
| Replace blade | Deck size and blade center hole pattern | Vibration, poor cut, unsafe fit |
| Order drive parts | Drive system style and wheel adjuster type | Mower will not self-propel correctly |
| Tune-up planning | Engine family and linkage style | Hard starting or surging |
Quick tip before ordering
Write the model number exactly as shown on the label (all digits), then confirm it against the parts list in the manual. This prevents mix-ups with similar Craftsman mower series.

What is the average lifespan of 917372270?
A Craftsman walk-behind mower like model 917372270 typically lasts 8 to 12 years with normal residential use and routine maintenance (oil changes, blade care, and clean fuel). Following the maintenance schedule in the 917372270 owner's manual is the most reliable way to reach that lifespan.
What most affects lifespan
- Engine care: clean oil at the right interval and correct oil type/level
- Fuel quality: fresh gasoline, clean carburetor, no long-term stale fuel storage
- Blade condition: a sharp, balanced blade reduces engine load
- Deck and airflow: keeping the underside clean prevents corrosion and improves cut quality
- Storage: dry storage and end-of-season prep reduce rust and starting problems
Quick maintenance targets (from the manual)
The manual lists key specs that support long life, including:
| Item | Spec for 917372270 | Why it matters |
|---|---|---|
| Oil capacity | 20 oz | Correct level prevents accelerated engine wear |
| Spark plug gap | 0.030 in | Proper ignition helps easy starts and smooth running |
| Blade nut torque | 70 to 75 ft-lbs | Keeps the blade secure and reduces vibration |
Signs your mower is nearing end-of-life (or needs major service)
- Hard starting even with fresh fuel and a good spark plug
- Noticeable vibration (often a bent blade or worn mounting hardware)
- Loss of power under normal grass load
- Excessive oil consumption or smoking
- Drive system slipping or inconsistent self-propel (if equipped)
Parts that commonly extend service life
Replacing wear items on time usually costs far less than replacing the mower:
- Blade 532406713 (a worn or bent blade strains the engine and hurts cut quality)
- Starter components if recoil starting becomes unreliable (handle, spring, pawl)
- Carburetor wear items if fuel leakage or flooding occurs (for example, needle/float parts)
Why it matters
A mower that is maintained to spec runs cooler, vibrates less, and puts less stress on the crankshaft, blade adapter, and drive components. That directly translates into more seasons of dependable starts and consistent cutting.
