Craftsman 917388562 lawn mower Parts

On Craftsman walk-behind mowers like model 917388562, we find the model and serial number on a decal located on the rear of the lawn mower housing. Use that model number to match the correct parts list and diagrams in your owner's manual.

Where to look on model 917388562

Check these common spots in this order:

• Rear of the mower deck (housing), near the back edge
• Rear panel area above the discharge opening (rear discharge models)
• Near the height adjuster brackets on the deck
• On the deck surface near the engine mounting area

Tips to read the decal (and what to write down)

The decal can be dirty or faded, so a quick cleanup helps.

• Wipe the area with a damp rag; avoid soaking the decal
• Use a flashlight at a low angle to make stamped/printed text easier to see
• Record both the model number and the serial number
• Take a clear photo for reference when ordering parts

Model number vs. serial number

Item	What it’s used for	Example for this mower
Model number	Identifies the exact mower design and parts breakdown	917388562
Serial number	Identifies your specific unit and production run	Varies by unit

Why it matters

Parts like the blade, blade adapter, control cable, and deck hardware can vary by model. Using the exact model number helps us match the right diagrams and the right replacement parts (for example, the husqvarna lawn mower 21-in deck 3-in-1 blade 532189028 for this model).

For your Craftsman lawn mower model 917388562, we recommend regular unleaded 87 octane. Using 89 octane will not improve performance in a properly running small engine; the key is using fresh fuel and storing it correctly (especially if the mower will sit for 30 days or more). See the fuel guidance in the owner's manual.

What fuel to use (and what to avoid)

• Use fresh, clean, regular unleaded gasoline (87 octane minimum).
• Do not mix oil with gasoline.
• Buy only what you can use in about 30 days to keep fuel from going stale.
• Avoid fuel with more than 10% ethanol (E10) when possible; higher ethanol blends can cause storage and fuel-system issues.
• If the mower will sit 30+ days, plan to run the fuel system dry or follow the storage steps in the manual.

87 vs 89: what changes and what does not

Higher octane is mainly for engines designed for it (high compression). Most walk-behind mower engines are tuned for regular fuel.

Fuel choice	What you can expect	Best use case
87 octane (regular)	Normal starting and power	Everyday mowing
89 octane (mid-grade)	No meaningful benefit	Only if 87 is unavailable

Why it matters

Old fuel and high-ethanol fuel are two of the most common causes of hard starting, surging, and poor power. Using the correct gasoline and keeping it fresh helps protect the carburetor, fuel lines, and overall engine reliability.

Common problems on the Craftsman 917388562 gas walk-behind mower include no-start conditions (fuel, spark, safety controls), loss of power from heavy grass or a dirty air filter, poor or uneven cutting from a worn or loose blade, and excessive vibration from blade or crankshaft issues. Use the owner's manual troubleshooting chart to match symptoms to fixes.

Most common symptoms and what usually causes them

• Won't start: stale fuel, dirty carburetor, fouled spark plug, control bar not held, fuel valve OFF (if equipped)
• Loss of power: cutting too much grass, dirty air filter, grass buildup under the deck, too much oil, walking speed too fast
• Poor cut or uneven cut: worn/bent/loose blade, uneven wheel height settings, debris packed under the mower
• Excessive vibration: loose or damaged blade, bent engine crankshaft
• Starter rope hard to pull: flywheel brake engaged when control bar is released, blade dragging in grass, broken blade adapter

Quick checks we recommend first (fast and safe)

1. Disconnect the spark plug wire before inspecting the blade or working under the deck.
2. Confirm the control bar is held firmly against the handle while starting.
3. Check fuel: drain old gas and refill with fresh fuel.
4. Inspect the air filter and replace if dirty.
5. Check oil level; overfilling can cause running problems.

Parts that commonly solve cutting and vibration complaints

If your mower is cutting poorly or vibrating, these model-matched parts are often involved:

Symptom	Common fix	Example part for this model
Uneven cut, ragged grass tips	Replace a worn/bent blade	21-in deck 3-in-1 blade 532189028
Blade feels loose or won't stay tight	Inspect blade mounting hardware	Lawn mower blade adapter 581547901
Deck packs with clippings	Clean underside; verify bagging setup	Grass bag 532410666

Why it matters

Ignoring power loss, vibration, or a hard-to-pull starter rope can lead to bigger failures (like blade adapter damage or crankshaft problems) and can make the mower unsafe to operate.

For a Craftsman walk-behind mower like model 917388562, the model number does not contain the build year. To find the year, we use the engine or mower serial number/date code and match it to the format shown in your owner's manual.

Where to find the numbers to decode

Look in these common spots on a Craftsman mower:

• Mower deck housing (sticker or stamped tag near the rear discharge area)
• Handle support area (near the height adjusters or handle brackets)
• Engine shroud (engine model/type and a separate engine code)
• Under the grass bag door (if equipped)
• Near the rear wheel brackets

How serial number formats usually work

Craftsman mowers and their engines can use different date-code styles. Here are the most common patterns we see:

• MMDDYY (month, day, year)
• YYMMDD (year, month, day)
• Julian date (a 3-digit day-of-year plus a year digit)
• Engine-specific code (letters and numbers where the year is embedded)

Quick examples (format only)

Example code	Common interpretation	Year shown
072811	MMDDYY	2011
110728	YYMMDD	2011
21107	Julian style (varies by maker)	depends

Tips to avoid a wrong year

These checks keep the lookup accurate:

• Use the full serial/date code, not just the first few digits.
• If you find both a mower tag and an engine tag, decode the engine code first; it is usually the most reliable for build date.
• If the code includes letters, write it exactly as shown (letters often matter).
• Confirm the mower is model 917388562 (shown in the manual) before ordering parts.

Why it matters

Knowing the correct year helps us match the right blade, blade adapter, control cable, and deck hardware for your mower. For example, this model uses parts like the walk-behind lawn mower engine cable 532176556 and the lawn mower blade adapter 581547901, and small changes by year can affect fit.
