Are gas lawn mowers being phased out?
Gas walk-behind mowers like the Husqvarna 917376970 are not being phased out everywhere at once, but new-sales restrictions in some areas and growing demand for battery mowers are steadily reducing gas mower availability over time. Your mower remains serviceable, and parts support keeps it running for years.
What “phased out” usually means (and what it does not)
Most changes focus on new equipment sales, not taking existing mowers out of service.
- Some regions restrict or plan to restrict new gas outdoor power equipment sales.
- Existing gas mowers are typically still allowed to be used, maintained, and repaired.
- Retailers may stock fewer gas models as electric options expand.
- Commercial and heavy-duty use cases often keep gas equipment in rotation longer.
- Parts like blades, belts, wheels, and grass catcher components still wear out and need replacement.
For model-specific operation and safety guidance, use the 917376970 owner’s manual.
How to plan for long-term ownership of a gas mower
If you want your 917376970 to stay reliable as the market shifts, focus on routine maintenance and wear items.
- Use fresh fuel; the manual allows gasoline up to 10% ethanol (E10).
- Keep the blade sharp and balanced; replace it when bent or cracked.
- Inspect the grass catcher and discharge components for wear and damage.
- Check fasteners after blade service; the manual lists blade bolt torque of 35 to 40 ft-lbs.
- Store safely: let the engine cool before storage and avoid storing with fuel indoors.

Why it matters
Even if gas mower sales decline in some areas, your Husqvarna 917376970 can deliver dependable performance with basic upkeep. Staying ahead of blade, belt, and bag wear prevents poor cut quality, drive problems, and unsafe operation.

How do I know what model my mower is?
Your Husqvarna walk-behind mower’s model number is on the mower’s ID label; for this unit it should read 917.376970. We recommend matching the full model number exactly (including dots) before ordering parts or using diagrams in the 917376970 owner's manual.
Where to find the model number on the mower
Check these common locations on Husqvarna walk-behind mowers:
- On the mower deck housing (often near the rear or side of the deck)
- Near the engine area, under or around the engine shroud
- On the handle support area or rear skirt area
- On a label that also lists a product number (this model’s product number is often shown as HU600F)
What to write down (so parts match)
Copy the identification exactly as it appears on the label.
- Model number: 917.376970
- Product number (if shown): HU600F
- Brand: Husqvarna
- Any extra suffixes or revision codes printed on the tag
Quick check table
| What you see on the label | What it means | Why we use it |
|---|---|---|
| Model No. 917.376970 | The mower model | Matches the correct parts diagrams |
| Product No. HU600F | Product identifier | Helps confirm the exact build |
| Engine info (example: Kohler XT149) | Engine family/model | Helps when buying engine-specific parts |
Why it matters
Using the exact model number prevents ordering the wrong blade, wheel, or drive parts. For example, the correct drive system parts list for this mower includes items like the lawn mower ground drive belt 532196853 and the lawn mower transmission assembly 589600601, which can vary by model.

Is 2 year old gasoline still good for a lawn mower?
No. For a Husqvarna walk-behind mower model 917376970, 2-year-old gasoline is stale and commonly causes hard starting, surging, and carburetor/fuel-system problems. Drain the old fuel, refill with fresh gasoline (up to E10), and follow the storage and fuel guidance in the 917376970 owner's manual.
What to do if 2-year-old gas is in the mower
- Move the mower outdoors and let the engine cool completely.
- Drain the fuel tank and dispose of old gasoline properly.
- Refill with fresh, clean gasoline (the manual allows gasoline with up to 10% ethanol, E10).
- If it still will not start or runs rough, clean the carburetor and check the air filter.
- If you suspect water in the fuel, drain and refill again; water contamination often mimics ignition issues.
Quick troubleshooting: symptoms and likely cause
| Symptom | Common fuel-related cause | What usually fixes it |
|---|---|---|
| Won’t start | Stale fuel or water in fuel | Drain tank, refill with fresh gas |
| Starts then dies | Varnish in carburetor jets | Carburetor cleaning |
| Surges at idle | Partially clogged carburetor | Carburetor cleaning, fresh fuel |
| Hesitates under load | Restricted fuel flow | Fresh fuel, inspect fuel path |
Why it matters
Old gasoline oxidizes and can form varnish that clogs small carburetor passages. Your 917376970 manual also calls out stale fuel and water in fuel as common “does not start” causes, and it recommends emptying and refilling with fresh, clean gasoline.
How to prevent this next time
- Do not store gasoline from one mowing season to the next.
- Use a clean, non-rusting gas can to reduce dirt and rust contamination.
- Run the mower regularly during the season so fuel does not sit for long periods.
- For off-season storage steps, follow the 917376970 owner's manual.
