Craftsman 917374430 lawn mower Parts

For your Craftsman walk-behind mower model 917374430, the quickest way to identify what you have is to match the mower model number and serial number from the rear housing decal, then use the separate mower and engine identifiers when looking up diagrams, manuals, and parts. See the 917374430 owner’s manual.

Where to find the identification numbers on model 917374430

On this Craftsman mower, the manual specifies that the model and serial numbers are on a decal on the rear of the lawn mower housing.

• Look on the rear of the mower deck/housing for a decal or sticker
• Write down the model number (917374430) and the serial number
• Keep the numbers with your paperwork for future parts lookups
• If the decal is dirty, wipe it gently so the numbers are readable

Why you may see two different “models” (mower vs. engine)

Many walk-behind mowers use:

• A mower model number (covers the deck, wheels, handle, drive system, bagging/mulching parts)
• A separate engine model/type/code (covers carburetor, ignition, recoil starter, air filter, etc.)

That is why you may find one set of diagrams for the mower and another for the engine.

What to record (and how you’ll use it)

What you’re identifying	Where it’s found	What it helps you get
Mower model and serial	Rear housing decal	Correct Craftsman parts diagrams and mower manual
Engine model/type/code	Engine shroud or valve cover label	Correct engine parts and tune-up components

Why it matters

Using the correct mower and engine identifiers prevents ordering the wrong blade, drive parts, or hardware. For example, when replacing a wear item like the lawn mower blade 532406713, matching by model helps ensure proper fit and safe cutting performance.

On Craftsman walk-behind mower model 917374430, the model and serial number are printed on a decal on the rear of the mower housing (deck). We recommend writing both numbers down exactly as shown before ordering parts or looking up specifications in the 917374430 owner's manual.

Where to look on model 917374430

Check these common spots on the mower deck:

• Rear of the mower housing, near the discharge door area
• Rear panel of the deck, above the wheels
• Near the height adjuster area on the deck (if the decal has shifted)
• Under heavy grass buildup (clean the area first)

Tips to make sure you copy the right number

Model numbers and serial numbers can look similar. Use these quick checks:

• Model number is typically a longer identifier (for this mower, it is 917374430)
• Serial number is unique to your specific mower
• Copy numbers exactly; include all digits
• If the decal is dirty, wipe it gently and let it dry before reading

Model vs. serial number (quick reference)

What you need	What it’s used for	Example for this mower
Model number	Finding correct diagrams and compatible parts	917374430
Serial number	Identifying production run details	Varies by unit

Why it matters

Using the exact model number helps us match the correct Craftsman parts (like a blade, drive belt, or wheel components) to your mower’s deck size and drive system, so you avoid returns and fit issues.

For Craftsman walk-behind mower model 917374430, we recommend fresh, clean, regular unleaded gasoline with a minimum of 87 octane. Do not mix oil with the gasoline; this mower uses separate engine oil. For the exact fueling and safety steps, use the 917374430 owner’s manual.

Fuel type and freshness guidelines

Using the right fuel helps prevent hard starting, surging, and carburetor varnish.

• Use unleaded regular, 87 octane (AKI) or higher.
• Buy fuel you can use within 30 days.
• Keep the gas can clean and sealed to reduce moisture and dirt.
• Avoid overfilling; fill only to the bottom of the filler neck.
• Wipe up spills before starting the engine.

Ethanol (E10) and storage tips

The manual notes that alcohol-blended fuels can attract moisture and cause fuel separation during storage. If you use ethanol-blended fuel, keeping it fresh matters even more.

Quick comparison

Fuel situation	What we recommend	Why it matters
Mowing weekly	Fresh 87+ octane unleaded	Best starting and performance
Fuel may sit 30+ days	Treat with stabilizer or run the tank/carburetor dry before storage	Helps prevent gum and varnish
End-of-season storage	Empty fuel system or stabilize and run engine 10 minutes	Reduces carburetor problems next season

If the mower runs rough after refueling

Stale fuel is one of the most common causes.

• Drain old fuel and refill with fresh unleaded
• Check the air filter for dirt buildup
• Inspect the spark plug condition and gap
• Make sure the primer is used correctly for cold starts

Why it matters

Fuel quality directly affects starting, power, and the life of the fuel system (tank, fuel line, carburetor). Fresh, correct-octane gasoline is one of the easiest ways to keep your Craftsman mower reliable.

For Craftsman walk-behind mower model 917374430, the model number “917” does not identify the year. To determine the year, we use the serial number/date code on the mower’s rear housing decal, then match that code to the manufacturer’s date format shown in the 917374430 owner’s manual.

How to find the build date on model 917374430

On this Craftsman mower, the manual notes the model and serial numbers are on a decal on the rear of the lawn mower housing. Use that decal to capture the information needed.

• Look for the rear housing decal (back of the deck)
• Write down the serial number exactly as shown
• If the decal includes a date code, record that too
• Take a clear photo before the decal fades further
• Keep the serial number with your maintenance records

Why “Model 917” is not the year

“917” is a Craftsman model prefix used across many different products and production years. The year is tied to the serial/date code, not the “917” prefix.

Identifier	What it tells you	What it does not tell you
Model number (917374430)	Exact mower configuration for parts lookup	The manufacturing year by itself
“917” prefix	Product line/manufacturer coding	The year
Serial/date code on decal	Production date information	Replacement part condition

Why it matters

Knowing the correct year helps when you are comparing manuals, confirming engine family changes, or ordering wear items like a lawn mower blade 532406713 that must match your exact deck setup.
