Craftsman 917376402 lawn mower Parts

The model number for this Craftsman walk-behind gas lawn mower is 917.376402 (often written without the dot as 917376402). You can confirm it on the mower’s model tag and in the 917376402 owner's manual.

Look for the model label in the most common locations:

• On the rear of the mower deck near the discharge opening
• On the top of the deck near the engine mounting area
• Near the handle mounting brackets
• In the documentation that came with the mower

Manufacturers and parts sites may show the same model in slightly different formats.

Using the exact model number 917376402 helps us match the correct parts diagrams and replacement parts for your mower, such as the blade, drive components, and handle hardware. For example, this model uses a 22-inch multi-cut blade like the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825.

To avoid mix-ups, we recommend:

• Copying the model number directly from the mower label
• Keeping the dot if your label shows it (917.376402)
• Matching the part name and part ID when selecting replacements

For a Craftsman lawn mower model 917376402, it’s cheaper to repair when the fix is routine maintenance or a single worn part; it’s smarter to replace when the engine or drive system has major, repeated failures and repair costs approach about half the price of a comparable new mower.

We use these quick rules to decide:

• Repair if the mower starts and runs well and the issue is wear-and-tear (blade, cable, wheels, bagging parts).
• Repair if the problem is maintenance-related (oil, spark plug, air filter, cleaning under the deck).
• Replace if the mower has recurring major problems (hard starting plus low power plus heavy smoke).
• Replace if the drive system or engine needs expensive work and the mower is already near end-of-life.
• Replace if safety or performance is compromised (persistent vibration after blade service, chronic stalling under load).

The 917376402 manual emphasizes maintenance as the best way to avoid costly repairs. Use these steps before deciding to replace:

• Follow the maintenance schedule in the 917376402 owner’s manual.
• Keep the blade sharp; replace a bent blade with an approved replacement such as the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 when needed.
• If the mower is self-propelled and won’t move, clean debris from the drive wheel area (hubcaps, locknuts, washers, dust cover, pinion gear teeth).
• Do not adjust engine speed or the governor; have a qualified service center handle speed issues.

Repairing makes sense when you’re restoring normal mowing performance with predictable parts and maintenance. Replacing makes sense when you’re paying repeatedly for major drivetrain or engine work and still not getting reliable starts, steady power, and consistent drive.

On a Craftsman walk-behind mower, the model number is printed on the mower’s ID label; for this unit it appears as 917.376402 (often shown without the dot as 917376402). Use that exact model number when looking up parts and diagrams in the 917376402 owner's manual.

Look for a sticker or metal tag on the mower housing, then wipe it clean so the numbers are readable.

• On the rear of the deck near the discharge opening or rear door area
• On the top of the deck near the engine mounting area
• Near the handle mounting brackets on the deck
• Around the wheel height adjuster area
• On the back panel near the grass bag or rear baffle

The label typically includes a model number and may also list an engine family or series (for example, a Briggs & Stratton series). For parts ordering, we match the mower by the mower model number first.

The model number ties your mower to the correct parts list and exploded-view diagrams. That prevents ordering a similar-looking part that will not fit, such as the wrong 22-inch blade, drive components, or handle hardware.

• Copy the model number exactly as printed
• If the label is worn, take a photo in bright light and zoom in
• Use the model number to confirm fit before choosing common wear items like the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825

On the Craftsman walk-behind mower model 917376402, the most common problems we see are no-start conditions, loss of power, poor cut quality, excessive vibration, and drive issues. These symptoms usually trace back to fuel quality, ignition parts, airflow, blade condition, or grass buildup; use the 917376402 owner's manual troubleshooting chart to match symptoms to fixes.

• Won’t start: stale fuel, dirty air filter, disconnected spark plug wire, bad spark plug, or a loose blade/blade adapter
• Loss of power: cutting too much grass at once, dirty air filter, grass buildup under the deck, or too much oil in the engine
• Poor cut (uneven or ragged): worn or bent blade, uneven wheel height settings, or deck packed with clippings
• Excessive vibration: bent/loose blade, damaged blade adapter, or (more seriously) a bent crankshaft
• Hard to push or loss of drive: drive system wear, debris binding the wheels, or transmission/drive components slipping

1. Start with fuel: drain old gas and refill with fresh, clean gasoline.
2. Check the air filter: replace if dirty or oil-soaked.
3. Inspect the blade and mounting: a loose or damaged blade can cause vibration and poor cutting.
4. Clean under the deck: packed grass reduces airflow and power.
5. Verify control bar operation: the engine brake and safety controls must fully engage.

If your mower shakes, cuts poorly, or leaves uncut strips, the blade is a top suspect. For this model, a common replacement is the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825.

Ignoring vibration, poor cutting, or repeated no-start issues can lead to bigger failures (damaged blade adapter, crankshaft stress, or premature drive wear). Fixing the basics early keeps your Craftsman mower cutting cleanly and running safely.
