Craftsman 917370602 lawn mower Parts

For the Craftsman walk-behind mower model 917370602, use fresh regular unleaded gasoline; in most areas that means 87 octane and up to 10% ethanol (E10). Avoid premium fuel unless your engine label or manual specifically calls for it; it does not improve performance in typical mower engines.

• Use fresh gas (ideally less than 30 days old).
• Use regular unleaded (typically 87 octane).
• E10 is commonly acceptable for walk-behind mowers.
• Avoid E15/E85 fuels; higher ethanol blends can cause hard starting and fuel-system issues.
• Avoid gas that smells sour, looks dark, or has water/debris in it.

• Buy gas in small quantities so it stays fresh.
• Keep the fuel cap area clean so dirt does not fall into the tank.
• If the mower will sit for 30+ days, treat fuel and run the engine briefly to circulate it.
• For off-season storage, follow the steps in the 917370602 owner's manual.

Using the right gasoline helps your Craftsman mower start easier, run smoother under load, and reduces carburetor varnish and fuel-line deterioration that can lead to no-start or surging.

On a Craftsman walk-behind mower like model 917370602, the model number is printed on the mower’s ID label (not on the engine). We use that mower model number to match the correct deck, handle, wheel, and drive parts for your exact machine.

Look for a sticker or metal tag on the mower body (deck) or handle area:

• Top of the mower deck near the rear discharge opening
• Back of the deck behind the engine (near the height adjusters)
• Side of the deck near a rear wheel
• On the handle support brackets or lower handle mount area
• Under the rear flap or near the bagging or mulching opening

Most Craftsman mower ID labels include a few key fields. Use the model number for parts lookup.

• Write the model number exactly as shown; include any dots or dashes if present.
• If the label is worn, wipe it clean and use a flashlight at an angle to make the print stand out.
• Use the mower model number for chassis parts; engine parts often use the engine’s separate model and type numbers.

The mower model number determines fit for critical items like the blade, drive system, and discharge components. For example, the correct blade for this mower is the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825, and using the wrong blade can cause poor cutting and vibration.

For diagrams and the exact label location guidance, use the 917370602 owner’s manual.

Common problems on a Craftsman walk-behind mower like model 917370602 usually fall into a few buckets: it will not start, it runs rough or stalls, it leaves an uneven cut, or the self-propel drive will not pull. Most fixes come down to basic maintenance, blade condition, and drive cable or transmission wear; see the 917370602 owner's manual for model-specific checks and adjustments.

• Will not start: old fuel, dirty carburetor, fouled spark plug, clogged air filter, stuck recoil starter
• Starts then dies / surges: restricted fuel flow, dirty carburetor jets, water in fuel, partially clogged air filter
• Poor cut quality / vibration: bent or dull blade, loose blade hardware, grass buildup under the deck
• Self-propel will not move: stretched/misadjusted drive cable, worn drive wheel components, worn transmission
• Clippings not discharging well: clogged deck, damaged deflector, mulching door not sealing

1. Turn the engine off and disconnect the spark plug wire.
2. Tip the mower with the air filter and carburetor side up (to reduce fuel/oil leakage).
3. Inspect the blade for bends, cracks, and heavy dulling; replace if damaged.
4. Check for packed grass under the deck and around the discharge opening.
5. If it is self-propelled, check cable tension and that the drive control bar fully engages.

Catching blade and drive problems early prevents deck damage, reduces vibration that can loosen fasteners, and helps the engine run under a steady load for cleaner cuts and longer mower life.
