Craftsman 917374542 lawn mower Parts

For the Craftsman lawn mower model 917374542, use regular 87-octane unleaded gasoline; higher octane (like 91) does not add power or protection in a mower engine. Also, use fuel with no more than 10% ethanol (E10) as noted in the 917374542 owner's manual.

Use these fuel guidelines to prevent hard starting, surging, and carburetor issues:

• Use fresh, clean unleaded gasoline (87 octane).
• Use E10 or less (up to 10% ethanol); avoid E15/E85.
• Buy only what you will use in 30 days (or treat with stabilizer).
• Keep the gas can clean and rust-free; dirt and rust cause fuel system problems.
• If the mower has been sitting, drain old fuel and refill with fresh gas.

Higher octane mainly resists knock in high-compression engines; most walk-behind mower engines are designed for regular fuel.

Using the right fuel helps your Craftsman mower start easier, run smoother, and reduces varnish buildup that can clog the carburetor and shorten engine life. Fuel quality is also a common cause of “won’t start” and “runs rough” symptoms.

If you are already doing seasonal maintenance, follow the storage and fuel-handling guidance in the 917374542 owner's manual so you do not carry old gas from one season to the next.

• Find the product identification label on the mower deck or rear housing area.
• Write down the serial number and any date code shown.
• Compare the format to the date-code explanation in the manual.
• If your mower has a Briggs & Stratton engine, also check the engine label for its date code.
• Use the date code to confirm whether your unit was built early or late in 2011.

Knowing the correct year helps you avoid ordering the wrong blade, belt, or drive parts when Craftsman made mid-year design changes. For example, the correct blade and drive components for model 917374542 include items like the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 and the drive belt listed for this model.
