Husqvarna 917380960 lawn mower Parts

The Husqvarna walk-behind mower model 917380960 is equipped with a 173cc Kohler engine (as shown on the cover of the 917380960 owner's manual).

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

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.

The engine brand and displacement affect maintenance and repair details such as spark plug type, air filter style, and carburetor settings. Using the correct engine identification also helps you choose compatible mower parts like the lawn mower ground drive belt, 3/8 x 35-3/8-in 532421527 when troubleshooting self-propelled drive issues.

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.

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.

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.

• 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

If you are also servicing the cutting system, we list the correct replacement blade for this model, including the lawn mower 22-in deck 3-in-1 blade 532420463. For more parts by model number, search on Sears PartsDirect.

For your Husqvarna 917380960 walk-behind mower, use fresh, clean unleaded regular gasoline; the manual lists unleaded regular as the correct fuel type, and gasoline with up to 10% ethanol (E10) is acceptable (more than E10 can cause problems). See the owner's manual for the fuel and capacity details.

Use fuel that matches these guidelines:

• Unleaded regular gasoline
• E10 (up to 10% ethanol) is OK
• Avoid gasoline over E10
• Avoid stale fuel (old gas is a common no-start cause)
• Avoid overfilling the tank; leave room for expansion

The manual lists the fuel tank capacity as 1.4 quarts.

These steps prevent hard starting and rough running:

• Shut the engine off and let it cool before refueling
• Fill outdoors and wipe up any spills
• Use a clean gas can; keep dirt and water out of the fuel
• If the mower has been sitting, drain/replace old fuel before troubleshooting
• Tighten the gas cap after filling

Correct fuel helps your mower start easily, run smoothly, and reduces issues like surging, stalling, and “won’t start” symptoms caused by stale fuel or contaminated gasoline.
