Craftsman 917388130 lawn mower Parts

The model number for this Craftsman walk-behind mower is 917.388130 (often written without the dot as 917388130). You can confirm it on the model tag and in the 917388130 owner's manual.

Where to find the model number on the mower

Check these common locations on Craftsman walk-behind mowers like model 917388130:

• On a label or plate on the rear of the deck (near the discharge opening)
• On the deck housing near the engine mounting area
• Near the height adjuster area on the deck side
• In the printed manual cover page and parts list

How to read the number correctly

Craftsman model numbers are sometimes shown with punctuation.

How it may appear	What it means
917.388130	Same model number, formatted with a dot
917388130	Same model number, formatted without a dot

Why the model number matters

Using the exact model number ensures we match the correct parts and diagrams for your mower, especially for items like the blade, blade adapter, wheels, and control cables.

If you are ordering a cutting part, match the model number first, then verify the part by description. For example, this model uses a 21-inch mulching blade option such as the lawn mower 21-in deck mulching blade 532406706 when the deck configuration calls for it.

Quick tip before ordering parts

• Confirm the model number from the mower tag (not just the engine tag)
• Use the model number to select the correct parts diagram section
• Compare the old part’s shape and mounting points to the replacement listing

For the Craftsman lawn mower model 917388130, we recommend using fresh 87-octane unleaded gasoline for normal operation. The bigger priority than octane is fuel freshness and cleanliness; stale or contaminated gas is a top cause of hard starting and rough running. See the fuel and operation guidance in the 917388130 owner's manual.

What to use (and what to avoid)

• Use fresh, clean unleaded gasoline from a clean gas can.
• 87 octane is the standard choice for most walk-behind mower engines.
• Avoid using old fuel that has been sitting for weeks or months.
• Avoid fuel contaminated with water, rust, or dirt.
• If your mower runs hot, pings, or surges, address maintenance items first (air filter, blade, fuel quality).

Quick decision guide

Situation	Best choice	Notes
Normal mowing, fresh fuel available	87 octane	Most common recommendation for small 4-cycle engines
Fuel has been stored a while	Replace with fresh fuel	Old fuel causes starting and running problems
You suspect rust or debris in the can	New clean can, fresh fuel	Rust and dirt in gasoline create performance issues
Engine pings under load	Fresh fuel + tune-up checks	Octane alone usually is not the fix

If you are having starting or running problems

The manual’s troubleshooting guidance points to fuel quality and basic ignition checks first. Use this order:

• Drain old gas and refill with fresh gasoline.
• Check for water in fuel (drain and refill if suspected).
• Inspect and service the air filter.
• Verify the spark plug wire is firmly connected.
• If you recently hit something, check for a loose blade or a worn adapter; the blade adapter 532418373 is a common wear item on many 21-inch decks.

Why it matters

Small air-cooled mower engines are sensitive to fuel condition. Fresh, clean gasoline helps prevent hard starting, surging, and stalling, and it reduces deposits that can affect carburetor performance.

On the Craftsman walk-behind mower model 917388130, the model number is printed on a decal on the rear of the lawn mower housing. Use that decal to record both the model and serial number for parts lookup and service reference; see the 917388130 owner's manual.

Where to look on the mower

Check these common spots first (starting with the most likely for this model):

• Rear of the mower deck (housing), on a decal near the back edge
• Rear-facing surface of the deck, above the discharge area
• Near the handle mounting brackets on the deck (if the decal was relocated)
• On the bagger door area or rear door assembly (if equipped)

What you should write down

The decal typically includes more than one identifier. Capture all of these:

• Model number (for this mower: 917388130)
• Serial number (unique to your mower)
• Date of purchase (helpful for maintenance records)

Model number vs. engine model number

Your mower has a Craftsman mower model number and a separate Briggs & Stratton engine model number. Use the right one depending on what you are doing.

You need to…	Use this number	Example you may see
Find mower deck, handle, wheels, bagger parts	Mower model number	917388130
Find engine-specific parts (carburetor, recoil starter, ignition)	Engine model number	126T02-0709-EA

Why it matters

Using the correct model number helps us match the exact parts diagram for your mower so you get the right blade, cable, or hardware the first time.

Craftsman model 917388130 is identified by model and serial or date information on the mower’s ID label; the model number itself does not contain a single “model year.” Use the ID label (and the Briggs & Stratton engine code as a backup) to determine the build year; see the 917388130 owner's manual for label locations and identification details.

Where to find the build year information

Check the mower first, then the engine.

• Mower ID label on the deck (top surface near the rear discharge area)
• Label near the handle brackets or height adjuster area
• Under the rear door or near the bagger opening
• Briggs & Stratton engine shroud label (engine model and code)

What to record (and how to use it)

Write the information exactly as shown; it is the most reliable way to pin down production timing.

• Model number: 917388130
• Serial number (if present)
• Any date code or “DOM” style marking on the mower label
• Engine code from the Briggs & Stratton label (useful if the mower label is missing)

Quick reference

If you find this	It tells you	Best use
Mower serial or date code	Mower production timing	Use this to identify the mower’s year/build period
Engine code	Engine build date	Use as a close indicator when mower label is unreadable
Model number only	Product family	Use for parts diagrams, not for year

Why it matters

Knowing the build period helps us match the correct walk-behind mower parts when there are mid-series changes (deck hardware, controls, or bagging components). For example, confirming the correct blade style before ordering a lawn mower 21-in deck mulching blade 532406706 prevents fit issues.

Tips to avoid ordering the wrong part

• Match the full model number: 917388130
• Compare your old part’s markings to the parts list in the manual
• If hardware is missing, match fasteners by size and application (example: lock nut 532409149)
