How to confirm the engine on your mower

We recommend matching the engine information on your machine to the manual and labels on the mower:

• Check the engine shroud label for Kohler branding and the engine family/model details
• Verify your mower model tag shows 917.380960
• Compare the engine displacement listed on the engine label to the manual (173cc)
• If you are ordering drive parts, confirm your exact configuration before buying

Common mix-up: 163cc vs 173cc

Some online listings for similar Husqvarna walk-behind mowers mention a 163cc Briggs & Stratton engine. For model 917380960, the documentation identifies a 173cc Kohler engine.

For Husqvarna lawn mower model 917380960, the maximum ethanol blend we use is E10, which means gasoline with up to 10% ethanol. Gasoline with more than 10% ethanol (such as E15) is not recommended for this mower and can cause performance problems.

What “E10” means (and what to avoid)

Ethanol blends are labeled by the percent of ethanol in the fuel.

• Use: Unleaded regular gasoline up to E10 (10% ethanol)
• Avoid: E15, E20, E85, or any fuel labeled “flex fuel”
• Avoid: Gasohol containing methanol (wood alcohol)
• Do not use: Ether or starting fluids (they can damage the engine)

For the exact fuel guidance and operating notes for this mower, follow the 917380960 owner's manual.

Quick fuel compatibility chart

Fuel label	Ethanol content	Use in 917380960?
E0	0%	Yes
E10	10%	Yes
E15	15%	No
E85	85%	No

Why it matters

Higher-ethanol fuel attracts moisture and can contribute to hard starting, rough running, and fuel-system issues during storage. Using the correct fuel helps protect the carburetor, fuel lines, and overall engine performance.

Tips to prevent fuel problems

• Buy fresh fuel in small quantities so it does not sit for months
• If the mower will sit, use a fuel stabilizer and follow the storage steps in the manual
• Replace old fuel if it smells sour or looks dark
• Keep the gas can clean and rust-free to prevent debris in the tank
