How many years should a lawn mower last?
A Craftsman walk-behind lawn mower like model 917370924 typically lasts 8 to 15 years with normal homeowner use. With consistent maintenance (oil changes, clean deck, sharp blade, and fresh fuel practices), many owners get 10+ years of reliable mowing.
Typical lifespan ranges
Lifespan depends most on hours of use per season, storage conditions, and how well the cutting and drive systems are maintained.
- 8 to 15 years is typical for a gas walk-behind mower
- 10+ years is common with routine tune-ups and clean storage
- Heavy weekly use, sandy soil, and wet mowing shorten life
- Neglected oil changes and a dull blade shorten engine and deck life
| Usage pattern | What we typically see | What helps most |
|---|---|---|
| Light (small yard, short season) | 12 to 15 years | Clean storage, fresh fuel |
| Average homeowner use | 8 to 12 years | Annual tune-up, blade care |
| Heavy use (large yard, long season) | 5 to 8 years | More frequent service, belt checks |
Maintenance that extends mower life
These are the highest-impact habits for a gas walk-behind mower like the 917370924.
- Change engine oil on schedule (more often in dusty conditions)
- Keep the underside of the deck clean to prevent corrosion and drag
- Sharpen or replace the blade when cuts look ragged
- Use fresh gasoline and avoid long-term storage with untreated fuel
- Inspect wear items like belts, wheels, and control cables each season
If your mower is leaving uneven cuts or vibrating, a worn or damaged blade is a common cause; the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 is one of the model-matched blade options listed for this mower.
Why it matters
A mower that is maintained cuts cleaner, runs cooler, and puts less strain on the engine and drive system. That reduces expensive failures and keeps your Craftsman mower safer and easier to operate.
For model-specific maintenance intervals and seasonal storage steps, follow the 917370924 owner's manual.

What kind of gas do I put in my lawn mower?
For the Craftsman lawn mower model 917370924, we recommend using fresh regular unleaded gasoline; in most walk-behind mower engines, 87 octane is the right choice, and E10 (up to 10% ethanol) is commonly acceptable. For the exact fuel guidance for your mower, follow the 917370924 owner's manual.
What to use (and what to avoid)
- Use fresh regular unleaded gas (typically 87 octane).
- Use E10 if that is what is available locally (up to 10% ethanol).
- Avoid old/stale fuel (more than about 30 days without stabilizer).
- Avoid E15/E85 fuels; higher ethanol blends can cause hard starting and fuel-system issues.
- Do not use race fuel or “premium only” gas unless the manual specifically calls for it.
Quick fuel guide
| Fuel type | OK for most walk-behind mowers | Notes |
|---|---|---|
| Regular unleaded (87) | Yes | Best everyday choice |
| E10 (10% ethanol) | Yes | Common at U.S. pumps |
| Premium (91-93) | Not needed | Usually no benefit |
| E15 | No | Higher ethanol than typical small-engine guidance |
| E85 | No | Too much ethanol for small engines |
Best practices for fewer starting problems
- Buy gas in small quantities so it stays fresh.
- If the mower will sit, add fuel stabilizer and run the engine a few minutes.
- Store fuel in an approved container, tightly sealed.
- If the mower won’t start after storage, drain old fuel and refill with fresh gas.
Why it matters
Using the right gasoline helps your Craftsman 917370924 start easier, run smoother, and reduces carburetor varnish and fuel-line deterioration that can lead to no-start or surging problems.

How do I find the model number on my 917370924?
The model number for your Craftsman walk-behind mower is printed on the mower’s model and serial number label. On most Craftsman mowers like model 917370924, that label is on the rear of the deck near the back wheels or on the rear handle bracket; confirm the exact label location in the 917370924 owner's manual.
Where to look on the mower
Check these common label locations first:
- Rear of the cutting deck (back edge, above the discharge area)
- Top of the deck near the engine mounting area
- Rear handle bracket or handle support area
- Under the rear flap or near the grass bag opening
- Side of the deck near a rear wheel height adjuster
What the label looks like
The label typically includes several identifiers. Use the model number for parts lookup.
| Label item | What it’s used for | Example format |
|---|---|---|
| Model number | Correct parts diagrams and part fit | 917.XXXXXX or 917XXXXXX |
| Serial number | Production run identification | Letters and numbers |
| Product number | Sometimes used on outdoor power equipment | Varies |
Tips to make sure you have the right number
- Write the model number exactly as shown (include dots or dashes if present).
- If the label is dirty, wipe it with a damp cloth; avoid soaking the label.
- If the label is worn, take a close-up photo and zoom in to read it.
- Use the model number (not the engine model) when ordering mower deck, drive, or handle parts.
Why it matters
Craftsman mower parts can look similar across different 917-series models, but belt routing, blade style, and control cables can differ. Using the exact model number helps ensure the correct diagrams and parts for your mower.
