Craftsman 917377610 gas walk-behind lawn mower Parts

Common problems on the Craftsman 917377610 gas walk-behind mower include no-start conditions (stale fuel, dirty air filter, bad spark plug, disconnected plug wire), loss of power from grass buildup under the deck, and vibration or poor cutting from a loose or worn blade or a damaged blade adapter. See the owner's manual for the model-specific troubleshooting chart and maintenance schedule.

Most common symptoms and what they usually mean

• Won’t start: stale fuel, water in fuel, dirty air filter, bad spark plug, or the control bar not held against the handle
• Loses power: deck packed with wet grass, cutting height too low, walking speed too fast, dirty air filter, oil level incorrect
• Poor cut or uneven cut: blade worn/bent/loose, wheel heights not set evenly, debris buildup under the mower housing
• Excessive vibration: blade damaged/loose, blade adapter damaged, crankshaft bent (often after striking an object)
• Starter rope hard to pull: blade dragging in grass, flywheel brake engaged when the control bar is released, or impact damage

Quick checks we recommend before buying parts

1. Drain and refill with fresh gasoline if fuel is old.
2. Clean the underside of the mower deck (grass and debris reduce airflow and power).
3. Verify all wheels are set to the same cutting height.
4. Inspect the blade and hardware; tighten the blade bolt.
5. Check the drive system if it is self-propelled and won’t move.

Parts that commonly solve cutting and vibration complaints

If the mower shakes, cuts poorly, or the blade feels loose, these are frequent wear items:

Self-propel won’t move or slips	Ground drive belt worn/stretched	Lawn mower ground drive belt 532160816

For ordering, we recommend using the parts list for model 917377610 first; you can also search by model number on Sears PartsDirect.

Why it matters

Most “big” mower problems start as basic maintenance issues: old fuel, restricted airflow, or grass packed under the deck. Fixing those first prevents repeat failures and helps the engine and drive system last longer.

• Check the decal on the rear of the mower housing
• Record both the model and serial number for future parts lookup
• Use the model number when selecting parts like a blade adapter, drive belt, or handle components
• Keep the number with your maintenance notes (oil changes, blade sharpening, tune-ups)

The Craftsman 917377610 model number identifies the mower series, not the build year. To find the year, use the serial number date code on the mower’s ID decal (typically on the rear of the mower housing) and match it using the identification details in the owner's manual.

Where to find the date information

On Craftsman walk-behind mowers like model 917377610, the model and serial numbers are listed on a decal attached to the mower housing. Once you have the serial number, you can decode the manufacture date.

• Look for the ID decal on the rear of the mower housing
• Write down the serial number exactly as shown
• Check for a date-coded pattern within the serial number
• Record your date of purchase too (helpful for maintenance and parts matching)

How the serial number date code is commonly read

Many Craftsman mower serial numbers use a MMDDYY style date code (month, day, year) within the serial number string. That means the last two digits typically indicate the year.

Example date code	Interprets as	Year shown
072811	July 28, 2011	2011
041514	April 15, 2014	2014
092009	September 20, 2009	2009

Why it matters

The correct year helps us match the right parts and specs for your mower’s exact configuration (engine components, drive system parts, and blade hardware). For example, if you’re replacing cutting parts, using the correct 21-inch blade and mounting hardware prevents vibration and poor cut quality.

Parts that often depend on correct identification

If you are ordering parts after you confirm the serial/date code, these are common items customers replace on this model:

• Husqvarna lawn mower mulching blade, 21-in 159267 (cut quality and vibration)
• Lawn mower blade adapter 581547901 (blade fit and alignment)
• Lawn mower ground drive belt 532160816 (self-propel drive)
• Lawn mower drive cable 532405995 (drive engagement)

You can order replacement parts from the parts list for model 917377610, or search by model number on Sears PartsDirect.

On a Craftsman gas walk-behind mower like model 917377610, the model number is typically printed on a model and serial number label attached to the mower deck or handle mounting area. Use that exact number when ordering parts or looking up specifications in the owner's manual.

Common places to check on model 917377610

• Top of the mower deck near the rear discharge opening or height adjuster area
• Side of the deck near a rear wheel bracket
• On the handle support or handle mounting bracket
• Near the engine mounting area on the deck (not on the engine itself)
• Under the grass catcher flap area (rear discharge models)

Mower model number vs. engine model number

Your mower has a mower model number and the engine has its own engine model number. For parts like wheels, belts, and handles, use the mower model number (917377610). For engine-specific items (carburetor, recoil starter, ignition parts), you may need the engine model number listed in the manual.

What you are identifying	Where to look	What it’s used for
Mower model number (917377610)	Label on deck or handle mount	Ordering Craftsman mower parts and diagrams
Engine model number	Stamped/printed on engine shroud or tag	Ordering engine parts and engine tune-up items

Why it matters

Using the correct model number prevents ordering the wrong blade, drive belt, or handle hardware. For example, common wear items for this mower include the husqvarna lawn mower mulching blade, 21-in 159267 and drive system parts like the lawn mower ground drive belt 532160816.

Quick tips for reading the label

• Write the model number exactly as shown (include all digits)
• If the label is dirty, wipe it with a damp rag and mild detergent
• If the label is faded, take a photo at an angle under bright light to make the print easier to read

If you need to order parts after you find the model number, you can use the parts list for model 917377610 or search by model on Sears PartsDirect.
