Craftsman 917377822 gas walk-behind lawn mower Parts

On the Craftsman 917377822 gas walk-behind mower, the most common problems we see are no-start or hard-start conditions, rough running, loss of drive (self-propel), excessive vibration, and uneven cutting. Many of these issues trace back to routine maintenance items or wear parts listed in the 917377822 owner’s manual.

Common issues and what they usually point to

• Won’t start / hard to start: stale fuel, dirty air filter, fouled spark plug, or a disconnected spark plug wire
• Runs rough or surges: fuel quality issues, dirty carburetor passages, restricted air flow
• Loss of power: grass buildup under the deck, cutting too low in heavy grass, low oil level
• Excessive vibration: bent or loose blade, damaged blade adapter
• Self-propel slows or won’t pull: worn belt, belt off pulley, stretched/broken drive cable

Quick checks we recommend first (fast, high-impact)

1. Disconnect the spark plug wire before inspecting anything near the blade.
2. Verify fresh fuel (used within about 30 days) and the correct oil level.
3. Inspect the blade for bends, cracks, or looseness.
4. Clean packed grass from the underside of the mower deck.
5. If self-propel is weak, inspect the drive cable and linkage; replace the lawn mower drive cable 583180101 if it’s stretched or damaged.

For the Craftsman gas walk-behind mower model 917377822, the owner’s documentation identifies it as a 7.0 horsepower mower but does not name a specific engine manufacturer on the pages we can validate here. In general, Craftsman walk-behind mowers have been built with engines from multiple suppliers depending on the production run.

How to identify the engine brand on model 917377822

The most reliable way is to read the engine’s own ID label, not the mower deck label.

• Look on the engine shroud (top cover) for a brand badge (Briggs & Stratton, Tecumseh, Honda, etc.).
• Find the engine model and type numbers stamped on the blower housing or valve cover.
• Check near the spark plug area and muffler heat shield for an ID sticker.
• Use the maintenance section in the 917377822 owner’s manual to confirm tune-up specs once you know the engine family.

Common engine brands used on Craftsman walk-behind mowers

Craftsman has used different engine brands across different mower models and years. These are the most common you’ll run into:

Engine brand	Where you’ll typically see it	What it affects for parts/service
Briggs & Stratton	Many Craftsman push and self-propelled mowers	Air filter, carburetor parts, ignition parts
Honda	Some Craftsman walk-behind models	Different spark plug and filter styles
Tecumseh (older)	Older Craftsman mowers	Legacy parts and older spec formats

Why it matters

The engine brand determines the correct spark plug, air filter, carburetor parts, and sometimes even the starter components. The mower model number (917377822) helps with deck and drive parts, but the engine ID is what locks in engine maintenance parts.

For Craftsman gas walk-behind mower model 917377822, the owner’s documentation identifies it as a Craftsman product sold and supported by Sears (Sears, Roebuck and Co.). The exact factory that built a given Craftsman mower can vary by production run, so the most reliable identifier is the model and serial tag plus the model-specific parts list in the 917377822 owner’s manual.

What we can confirm for model 917377822

From the model-specific manual, this mower is presented as a Craftsman rotary lawn mower with Sears listed as the supporting company.

Why you may see different “makers” mentioned

• Brand owner/seller (Craftsman via Sears support) is not always the same as the factory builder
• Parts listings can show supplier names for specific components
• Model-number “prefix rules” are not a guaranteed way to identify the builder for every unit

Example of a component supplier vs. the mower brand

Some compatible parts for this model include supplier-labeled components, such as the american yard products lawn mower anti-fold bracket 586122501. That indicates a component source, not necessarily the sole manufacturer of the complete mower.

Why it matters

For Craftsman walk-behind mower model 917377822, we can’t determine the build year from the serial number using the model-specific information available; the 917377822 owner’s manual shows where to find the serial number decal, but it does not include a serial-number-to-year decoding chart.

Where to find the serial number on model 917377822

The manual states the model and serial numbers are on a decal on the rear of the lawn mower housing.

• Look on the rear of the mower deck (housing)
• Brush off grass and dirt so the decal is readable
• Write down the full model number (917377822) and the entire serial number
• Take a clear photo of the decal for reference
• If the decal is worn, check nearby areas on the deck for a secondary label

How to identify the year when the serial code isn’t published

Because Craftsman serial formats can vary by production run and supplier, the most reliable way is to use the exact serial number from your decal and have it matched in a manufacturer or service database.

• Use the model number + serial number together (both are needed)
• Compare the mower’s features to the correct parts diagrams for 917377822
• If you’re replacing drive components, confirm the exact part match before ordering

What you might see on the decal

Decal detail	What it means	Year result
“Date of purchase” (you wrote it in)	Owner-recorded date	Not the build year, but a good clue
Only model and serial	Identification only	Year must be verified another way
Separate “DOM” or “MFG DATE” field	Direct manufacture date	Use that year

Why it matters

Knowing the correct year or production version helps prevent ordering the wrong maintenance or drive parts for your Craftsman mower, especially when designs change within the same model series.
