Craftsman 917374367 lawn mower Parts

For Craftsman model 917374367, the serial number tells you the mower’s build identity, but the most reliable way to establish “how old” it is is to match the serial number on the mower’s decal to your recorded purchase date and any date code format shown in the 917374367 owner’s manual.

Where to find the serial number on this mower

The model and serial numbers are on a decal on the rear of the lawn mower housing.

• Look at the rear of the mower deck (housing) for the decal
• Write down the full serial number exactly as shown
• Record the date of purchase (if you still have it)
• Keep the information with your maintenance records

How to estimate the mower’s age from the serial number

Many walk-behind mowers use a serial number that includes a date code (often year and month, sometimes month and day). Once you locate the serial number, check for a pattern like these:

• YYMMDD (year, month, day)
• MMDDYY (month, day, year)
• YYMM (year, month)
• A leading 2-digit or 4-digit year embedded near the start

Quick decode examples (common formats)

If the serial starts with	Read it as	Example meaning
YYMMDD	Year-Month-Day	230615 = June 15, 2023
MMDDYY	Month-Day-Year	061523 = June 15, 2023
YYMM	Year-Month	2306 = June 2023

Why it matters

Knowing the approximate build date helps us choose the right maintenance parts (blade, belt, cables) and confirm compatibility when you are troubleshooting issues like poor cut quality, drive problems, or worn controls.

For the Craftsman 917374367 gas walk-behind mower, we recommend using regular 87-octane unleaded gasoline; higher octane (like 91) does not add power or protection in this type of small engine. Use fresh fuel and keep ethanol at 10% (E10) or less as noted in the 917374367 owner's manual.

Fuel type guidelines (what works best)

• Use fresh, clean unleaded gasoline.
• Use 87 octane for normal operation.
• Use gasoline with up to 10% ethanol (E10).
• Avoid fuel over E10 because it can create fuel-system issues and can void warranty coverage per the manual.
• If the mower will sit 30 days or longer, empty the tank and run the engine until the carburetor is dry.

87 vs 91: what changes and what does not

Higher octane is mainly for engines designed for it (typically higher compression). Most walk-behind mower engines are designed to run correctly on regular fuel.

Fuel choice	What you get	When to use it
87 octane (regular)	Correct combustion for most mower engines	Everyday mowing
91 octane (premium)	No performance benefit in most mowers	Only if your manual specifically requires it
E10 or less	Acceptable per manual	Normal fueling
Over E10	Higher risk of storage and fuel-system problems	Avoid

Why it matters

Using the right fuel helps prevent hard starting, stale-fuel varnish in the carburetor, and fuel-system corrosion during storage. The manual also calls out ethanol limits, which protects long-term reliability.
