Craftsman 917370444 lawn mower Parts

The most common issues we see on the Craftsman 917370444 walk-behind gas mower are drive problems (won’t self-propel or slips), poor cutting quality (uneven cut or vibration), and discharge or mulching problems (clogging or poor bagging). Many of these trace back to normal wear items and simple adjustments listed in the owner's manual.

Common problems and what usually causes them

• Self-propelled drive won’t move or is weak: worn or stretched belt, cable out of adjustment, worn drive components.
• Mower vibrates or cuts unevenly: bent or dull blade, loose blade hardware, damaged blade adapter.
• Grass clumps, poor bagging, or side discharge issues: clogged deck, damaged deflector, weak chute door springs.
• Hard starting (electric start models): weak battery, charger issue, wiring connection problems.
• Wheels not driving evenly: worn pawls or pinion gear, debris in wheel drive.

Quick checks we recommend before buying parts

1. Shut off engine and remove the spark plug wire before inspecting under the deck.
2. Tip the mower safely (air filter and carburetor side up, per the manual).
3. Check the blade for damage and tightness; inspect the blade adapter for rounding or cracks.
4. Inspect the drive system for belt wear and cable slack.
5. Clean packed grass from the deck and discharge path; verify the deflector and chute door move freely.

For the Craftsman lawn mower model 917370444, we recommend using fresh regular unleaded gasoline; in most areas that means 87 octane. Gasoline with up to 10% ethanol (E10) is typically fine for walk-behind mower engines, but avoid higher-ethanol blends.

What to use (and what to avoid)

• Use fresh, clean regular unleaded fuel (commonly 87 octane).
• Use E10 if that is what is readily available.
• Avoid E15, E20, E85 and other higher-ethanol blends.
• Avoid old gas (especially fuel that has been sitting for weeks or months).
• Avoid mixing oil into the gas unless your mower is specifically a 2-cycle engine (most Craftsman walk-behind mowers like this are 4-cycle).

Quick fuel guide

Fuel type at the pump	OK for most walk-behind mowers?	Why
Regular unleaded (87)	Yes	Reliable combustion and easy starting
E10 (10% ethanol)	Yes	Common and generally compatible
E15 or higher ethanol	No	Can cause hard starting and fuel system issues
Premium (91-93)	Not needed	Usually provides no benefit in small engines

Best practices for fewer starting and running problems

• Buy gas in small quantities so it stays fresh.
• If the mower will sit, run the engine a few minutes after fueling so fresh gas reaches the carburetor.
• Keep the fuel cap area clean so debris does not fall into the tank.
• For storage, follow the fuel and storage steps in the 917370444 owner’s manual.

Why it matters

Using the right fuel helps prevent varnish buildup in the carburetor, reduces hard-start complaints, and keeps the engine running smoothly under load when cutting thicker grass.
