What kind of gas do I put in my lawn mower?
For the Craftsman lawn mower model 917374552, use fresh regular unleaded gasoline; gasoline with up to 10% ethanol (E10) is acceptable. Avoid fuels with more than 10% ethanol because they can cause fuel-system problems and can void the product warranty. See the 917374552 owner's manual for fuel and storage details.
Fuel type to use (and what to avoid)
- Use regular unleaded gasoline (fresh, clean fuel).
- E10 (up to 10% ethanol) is OK for this mower.
- Avoid E15, E20, E85, or any fuel labeled more than 10% ethanol.
- Avoid old fuel; stale gas is a common reason a mower will not start.
- Keep fuel clean; dirt or rust from a bad gas can leads to carburetor issues.
Quick fuel guidance table
| Fuel label at the pump | OK for 917374552? | Why |
|---|---|---|
| Unleaded (ethanol-free) | Yes | Clean, stable fuel choice |
| E10 | Yes | Allowed by the manual |
| E15 or higher | No | Exceeds 10% ethanol limit |
Storage and “stale gas” prevention
Alcohol-blended fuels can attract moisture during storage, which can lead to fuel separation and acids that damage the fuel system. For storage of 30 days or longer, we recommend:
- Empty the gas tank.
- Start the engine and let it run until the fuel lines and carburetor are empty.
- Refill with fresh gasoline next season.
For step-by-step seasonal prep, use how to winterize a lawn mower.
Why it matters
Using the right gasoline helps your Craftsman 917374552 start easier, run smoother, and reduces carburetor and fuel-line problems that often show up after storage.

What year is my Craftsman mower serial number lookup?
On Craftsman walk-behind mower model 917374552, the serial number is on a decal on the rear of the mower housing; the year is determined by decoding that serial number, not the model number. Use the format shown in your Craftsman 917374552 owner's manual to record the serial number and purchase date.
Where to find the serial number (917374552)
Look for a decal on the rear of the lawn mower housing.
- Tip the mower only as recommended in the manual (fuel and oil can spill)
- Wipe grass and dirt off the rear housing so the decal is readable
- Write down the full serial number exactly as shown
- Record the date of purchase if you still have it
How to decode the year from the serial number
Many Craftsman mower serial numbers use a date-coded pattern where the digits represent a build date (often month, day, then year). If your serial number appears to be in a 6-digit date format, it is commonly read like this:
| Serial digits | Meaning | Example |
|---|---|---|
| 1st-2nd | Month | 07 = July |
| 3rd-4th | Day | 28 = 28th |
| 5th-6th | Year | 11 = 2011 |
Quick checks to avoid a wrong year
- If the “month” portion is higher than 12, your serial number is likely not in MMDDYY format
- If the “day” portion is higher than 31, it is likely not MMDDYY format
- If your mower has electric start and a battery system, match features to the equipment description in the manual to confirm you are decoding the correct unit
Why it matters
Knowing the correct build year helps you match the right Craftsman parts (blade, drive belt, control cable) and avoid ordering look-alike components that do not fit your exact mower.

What is the average lifespan of 917374552?
A Craftsman walk-behind mower like model 917374552 typically lasts 8 to 10 years with normal residential use and routine maintenance (oil changes, blade care, clean deck, and proper storage). Heavy use, dusty conditions, and skipped maintenance shorten that lifespan.
What most affects mower lifespan
- Engine maintenance: clean oil, clean air filter, fresh fuel
- Blade condition: a bent or dull blade increases vibration and engine load
- Deck care: grass buildup holds moisture and accelerates rust
- Drive system wear: belt, cable, and transaxle wear from hills and frequent self-propel use
- Storage: dry storage and off-season prep prevent corrosion and fuel issues
Quick maintenance schedule (typical)
| Task | Typical interval | Why it matters |
|---|---|---|
| Change engine oil | Every season or ~25 hours | Reduces internal engine wear |
| Sharpen/replace blade | 1 to 3 times per season | Improves cut, reduces strain |
| Clean underside of deck | After mowing or weekly | Prevents rust and clogging |
| Inspect drive belt/cable | Each season | Prevents loss of self-propel |
Signs your 917374552 is nearing end-of-life
- Hard starting even with fresh fuel and a tuned ignition system
- Excessive vibration (often tied to blade or blade adapter issues)
- Self-propel slipping or not pulling consistently
- Deck rust-through or cracking around mounting points
Parts that commonly extend service life
Replacing wear items on time keeps the mower cutting and driving correctly:
- Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 (clean cut, less vibration)
- Lawn mower ground drive belt, 3/8 x 35-3/8-in 532421527 (restores self-propel traction)
- Lawn mower drive control cable 583502501 (improves drive engagement)
Why it matters
Knowing the typical 8 to 10 year lifespan helps you decide whether to invest in maintenance parts (blade, belt, cable) or plan for a replacement, especially if the deck or drive system shows major wear. For model-specific maintenance and safety steps, follow the 917374552 owner's manual.
