Craftsman 917388980 lawn mower Parts

On the Craftsman walk-behind mower model 917388980, the model and serial number are printed on a decal on the rear of the mower housing (rear of the deck). Use that exact model number when ordering parts and checking specifications in the 917388980 owner's manual.

Check these common spots on the rear of the deck (mower housing):

• Back of the deck, near the handle mounting points
• Rear panel area above the discharge opening
• Near the height-adjustment brackets on the rear corners
• On a decal that also has a serial number and purchase/date fields

Record both numbers so we can match the correct parts list and diagrams for your exact build.

• Model number: identifies the mower platform (for example, 917388980)
• Serial number: identifies the production run
• Date of purchase: helpful for maintenance tracking and service history

Craftsman walk-behind mowers often share similar deck and handle designs, but small differences (like a control cable length, wheel style, or discharge components) can change which replacement part fits. Using the exact model number helps prevent ordering the wrong part.

For a Craftsman walk-behind mower like model 917388980, the most reliable way to identify the build year is to use the model and serial number tag on the mower and match the serial/date code format shown in the 917388980 owner's manual. Many Craftsman serial tags use a date-style code where the last two digits indicate the year.

On walk-behind mowers, the tag is commonly found on the mower deck (often near the rear, side, or above the discharge area). Look for:

• Model number: 917388980 (this identifies the exact mower family)
• Serial number: a longer code that may include a date segment
• Engine information: sometimes listed separately on the engine shroud

Craftsman has used more than one serial format over the years. These are the most common patterns customers see:

• MMDDYY (6 digits): first two digits are month, next two are day, last two are year
• A longer serial with a date segment: the date may be embedded within the full serial
• Letter + digits formats: some versions use a single digit within the code to represent the year

If the tag is worn or missing, these steps still help narrow it down:

• Compare the mower’s handle and control layout to the diagrams in the manual
• Check for original hardware and assemblies (handle knobs, discharge parts, wheel style)
• Use the illustrated parts list to confirm you have the correct model family

If your mower matches model 917388980, these parts commonly appear in the parts breakdown:

• Upper handle 532194179
• Guide.rope.s 586122501
• Discharge guard 589482402

The correct year (and exact model) helps ensure you get the right blade adapter, control cable, wheels, and fasteners; small design changes across years can affect fit and safety.

For a Craftsman 917388980 walk-behind mower, it’s usually cheaper to repair when the problem is routine maintenance or a small wear part; replacement makes more sense when the engine or drive system needs major work or when repair cost is about half the price of a comparable new mower.

Use this quick rule: repair if the fix is simple and the mower is otherwise in good shape; replace if multiple major issues stack up (hard starting plus poor cutting plus wheel/handle damage).

Common “repair-first” situations:

• Dull, bent, or damaged blade (the manual recommends keeping the blade sharp and replacing bent/damaged blades)
• Clogged deck or poor bagging (cleaning under the deck is routine maintenance)
• Normal tune-up items (spark plug, air filter, oil check)
• Loose hardware or handle issues (often just fasteners or adjustments)
• Worn control cable symptoms (engine stops when you release the control bar)

Common “replace-or-major-repair” situations:

• Low compression, heavy smoke, or persistent knocking (engine internal wear)
• Repeated no-start after fuel system and ignition basics are addressed
• Structural damage to the deck/housing from impacts
• Multiple expensive problems at once (engine plus wheels/handle plus controls)

A well-maintained mower cuts cleaner, bags better, and runs cooler. Your manual calls out regular maintenance (spark plug, air filter, blade checks, cleaning under the deck), which prevents the “small problem becomes big repair” cycle.

• Follow the maintenance schedule in the 917388980 owner’s manual.
• Keep the blade sharp; a dull blade strains the engine and worsens cut quality.
• Clean under the deck regularly (built-up clippings increase drag).
• Avoid impacts; the manual advises stopping and inspecting after striking an object.
• Never adjust wheel height with the engine running.
