Craftsman 917371130 rotary lawn mower Parts

On the Craftsman rotary lawn mower model 917371130, the serial number is recorded from the decal on the rear of the mower housing. We use that serial number to identify the exact production run so you get the right parts and service information; see the 917371130 owner's manual for the decal location.

Where to find the serial number on model 917371130

Look for a decal on the rear of the lawn mower housing (deck).

• Tip the mower only as recommended in the manual (to avoid fuel or oil spills)
• Wipe grass and dirt off the rear deck area so the decal is readable
• Record the model number and serial number exactly as printed
• Also write down the date of purchase (the manual provides a space for it)

How to interpret the serial number

Craftsman serial-number formats vary by mower family and manufacturing source. For this model, the most reliable approach is to use the serial number as an identifier (not as a guaranteed date code) when ordering parts or checking specifications.

• Use the full serial number, including any letters
• Do not drop leading zeros
• If the decal is worn, take a clear photo and zoom in to confirm characters
• Match parts by model 917371130 first, then confirm with the serial number

Quick reference: model number vs. serial number

Item	What it tells us	Where it’s used
Model number (917371130)	The mower design and parts breakdown	Parts diagrams, repair parts lists
Serial number	The specific unit and production run	Verifying correct part variations

Why it matters

Using the correct serial number helps prevent ordering the wrong blade, control cable, or hardware when there are mid-production changes. For example, confirming fitment is especially important for wear items like the lawn mower blade 532406712 and control components.

For the Craftsman 917371130 rotary lawn mower, we recommend using fresh regular unleaded gasoline (87 octane). Higher octane (like 91) does not make the engine run better in this type of mower; fuel freshness and proper storage matter far more for reliable starting and smooth running.

What to use (and what to avoid)

• Use fresh 87 octane unleaded gasoline.
• Avoid stale fuel; it is a top cause of no-start conditions.
• Avoid leaving fuel sitting in the tank for 30 days or longer without proper storage steps.
• Be cautious with alcohol-blended fuels (gasohol/ethanol/methanol); they can attract moisture and cause fuel separation during storage.
• Never add engine or carburetor cleaner products directly into the fuel tank.

Storage guidance (prevents most fuel problems)

If you will store the mower for 30 days or longer, we follow the storage method in the 917371130 owner's manual: empty the gas tank, start the engine, and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season.

Quick storage checklist

• Let the engine cool completely before storing.
• Store the mower in a ventilated area away from ignition sources.
• Run the engine until it stops after emptying the tank (long-term storage).
• Use a clean, non-rusting gas can to reduce dirt and rust contamination.

Why octane is not the main issue

Octane mainly relates to resistance to knock in higher-compression engines. Most walk-behind mower engines are designed to run correctly on regular fuel, so 91 octane is usually unnecessary.

Fuel choice	Best use	What it helps most
87 octane (regular)	Everyday mowing	Correct operation and value
91 octane (premium)	Not needed for normal use	Typically no performance gain
Fresh fuel (any octane)	Always important	Starting, smooth running, fewer carb issues

Why it matters

Using the right fuel practices helps prevent hard starting, rough running, and carburetor problems. In the manual troubleshooting guidance, stale fuel and water in fuel are common causes when a mower does not start.

Where to confirm the model number

We use the mower’s model tag and the manual’s “Model No.” line to match parts and diagrams correctly.
