Craftsman 917378341 lawn mower Parts

For a Craftsman walk-behind mower like model 917378341, we look up the model number by finding the model and serial tag on the mower deck or frame, then entering that exact number when searching for parts and diagrams. Use the 917378341 owner's manual to confirm the label location and format.

On most Craftsman walk-behind mowers, the model and serial information is on a sticker or metal tag in one of these common spots:

• On top of the mower deck near the engine
• On the rear of the deck near the bagger door
• On the side of the deck by a rear wheel
• On the frame near the handle mounting points
• Near the height adjuster area

Once you have the model number, match it exactly (including dots or dashes if shown on the tag). Then use it to pull the correct parts list and diagrams.

• Write the model number exactly as printed
• Record the serial number too (helps with production variations)
• Use the parts diagrams to identify the correct part name and reference number
• Order by the Sears PartsDirect part ID when possible to avoid mix-ups

If you are replacing a wheel or drive component, matching the model number first prevents ordering the wrong diameter wheel, belt length, or mounting hardware.

Craftsman model numbers identify the exact deck, drive system, and engine family used on your mower. Even small differences can change which control cable, wheel, or belt fits.

Common problems on the Craftsman 917378341 gas walk-behind mower include hard starting from priming issues, loss of power from a dirty air filter or grass buildup under the deck, uneven cutting from incorrect wheel height settings, and excessive vibration from a worn, bent, or loose blade. See the 917378341 owner's manual for the model-specific troubleshooting chart.

• Won’t start or starts then dies: over-priming (flooding), stale fuel, dirty air filter
• Loss of power: cutting too much grass at once, deck packed with clippings, oil level too high
• Uneven cut: wheel heights set unevenly, blade worn or bent
• Excessive vibration: blade loose or damaged, bent crankshaft after an impact
• Starter rope hard to pull: blade dragging in grass, blade adapter damage, flywheel brake engaged when the control bar is released

1. Set the mower to a higher cut if the grass is tall or thick.
2. Clean the underside of the mower housing (grass and debris reduce airflow and power).
3. Inspect the blade for bends, cracks, or looseness; tighten hardware as needed.
4. Check and correct the engine oil level.
5. Clean or replace the air filter if it is dirty.

If you find worn or damaged drive or height-adjust components during inspection, these model-matched parts are commonly involved:

Most “mower problems” are really performance issues caused by load (grass too tall), restricted airflow (dirty filter or packed deck), or blade condition. Fixing those first restores power, improves cut quality, and reduces vibration that can damage the crankshaft.

The model number is 917.378341 (often written without the dot as 917378341) for this Craftsman walk-behind rotary lawn mower; you can confirm it in the 917378341 owner's manual.

We recommend checking the mower’s model tag first, then matching it to the manual.

• Look on the rear of the deck near the discharge area
• Check near the handle mounting brackets
• Look around the engine mounting area on the deck
• Wipe off grass and dirt so the full number is readable

This mower has its own model number, and the engine can have a different model number.

Using the correct model number ensures you get parts that fit the Craftsman 917378341 deck and drive system (for example, the drive belt, wheels, and control cable routing). Ordering by a different product family name can lead to mismatched parts.

The model number 917378341 identifies a Craftsman rotary walk-behind gas lawn mower, not a riding mower; the year is not encoded in the model number itself. For the most accurate manufacture date, we use the product ID/serial information shown on the mower and the identification details listed in the 917378341 owner's manual.

We date a Craftsman mower by matching the serial number and product label information to the manufacturer’s records (the model number alone is not enough).

• Find the model and serial label on the mower deck or rear housing (location varies by build)
• Write down the full serial number exactly as shown
• Note any engine model number on the engine shroud (this mower commonly uses a Craftsman engine listed in the manual)
• Compare the label details to the identification section in the manual
• Use the serial and engine numbers when ordering parts or requesting service

Many Craftsman riding mowers use model numbers that start with 917, so it is easy to mix them up. Your 917378341 documentation and parts breakdowns are for a walk-behind rotary mower, including drive and handle components.

The 917378341 owner's manual lists this mower as Craftsman ROTARY LAWN MOWER and shows assemblies such as the gear case and drive system. If you are troubleshooting drive issues while you confirm the model, these parts are commonly involved:

• Control cable 532168552 (drive/control engagement)
• Lawn mower ground drive belt 532175436 (self-propel motion)
• Walk-behind lawn mower engine pulley 582940301 (belt drive at the engine)

Knowing the correct year and exact model helps us match the right blade, belt, cable, and hardware the first time, and it prevents ordering parts for a similarly numbered riding mower.
