What are the most common issues with 917376657?
The most common issues we see with the Craftsman 917376657 walk-behind gas mower are drive problems (self-propel not pulling), poor cutting quality, and bagging or discharge troubles. These usually trace back to wear items like the drive belt, wheels/pawls, blade and adapter, or the rear door and deflector setup; use the owner's manual for the correct adjustments and safety steps.
Common problems and what they point to
- Self-propelled drive slips or won’t move: worn or stretched belt, worn drive wheel/pawl, or a loose/misadjusted drive control cable.
- Cuts unevenly or leaves strips: dull/bent blade, damaged blade adapter, or deck height set unevenly side-to-side.
- Excess vibration: blade damage, blade adapter wear, or loose mounting hardware.
- Poor bagging or clumping: grass bag airflow restriction, rear door not sealing, or mowing too fast in wet/tall grass.
- Discharge chute won’t stay closed: weak or broken deflector spring or damaged deflector.
Quick checks we recommend (before buying parts)
- Disconnect the spark plug wire and tip the mower safely as described in the owner's manual.
- Inspect the blade for bends, heavy nicks, or a rounded cutting edge.
- Check the drive system for belt glazing/cracks and verify the drive control cable has proper tension.
- Spin the rear wheels by hand; binding or skipping often indicates wheel/pawl wear.
- Confirm all four height adjusters are set to the same notch.
Parts that commonly solve these symptoms (when worn)
| Symptom | Likely wear item | Example part for this model |
|---|---|---|
| No/weak self-propel | Drive belt | Belt 532157769 |
| Poor cut, scalping, strips | Blade | Lawn mower 22-in deck mulching blade 532406713 |
| Blade won’t stay tight or wobbles | Blade adapter | Lawn mower blade adapter 532421176 |
| Won’t bag well | Bag or rear door sealing | Lawn mower grass bag 532401963 or rear door 532401813 |
Why it matters
On the 917376657, the blade and drive components are wear items; replacing them on schedule restores cut quality, reduces vibration, and prevents extra strain on the transmission and cables.

What is the average lifespan of 917376657?
A Craftsman walk-behind mower like model 917376657 typically lasts 8 to 12 years with normal residential use and routine maintenance (oil changes, blade care, clean air filter, and proper storage). Heavy use, dusty conditions, and skipped maintenance shorten lifespan.
What most affects lifespan
- Engine maintenance: clean oil and a clean air filter prevent premature wear
- Blade condition: a bent or dull blade increases vibration and engine load
- Drive system wear (self-propelled models): belt, pulleys, and transmission wear over time
- Deck care: keeping the underside clean reduces rust and improves airflow
- Storage: dry storage and fuel management reduce corrosion and carburetor issues
Typical lifespan by usage
| Usage pattern | Typical lifespan | What to watch for |
|---|---|---|
| Light (small yard, weekly) | 10 to 12 years | normal blade and wheel wear |
| Moderate (average yard, seasonal) | 8 to 10 years | drive belt and cable adjustments |
| Heavy (large yard, frequent, rough terrain) | 5 to 8 years | transmission, wheels, deck corrosion |
Parts that commonly extend service life
Replacing wear items on time keeps the mower cutting cleanly and reduces strain on the engine and drive.
- Lawn mower 22-in deck mulching blade 532406713 (sharp blade, less vibration)
- Belt 532157769 (restores self-propelled drive performance)
- Lawn mower transmission assembly 532415226 (fixes slipping or no-drive conditions)
- Lawn mower drive wheel 532403111 (improves traction and drive engagement)
Why it matters
A mower that is maintained and repaired early usually costs less to keep running and delivers a cleaner cut; waiting until parts fail can lead to extra wear on the engine, deck, and drive components.
For model-specific maintenance intervals and procedures, follow the owner's manual.

What model number is a Craftsman 6.75 lawn mower?
A “Craftsman 6.75” label usually refers to the engine series (often a Briggs & Stratton 625 Series), not the mower’s model number. For the Craftsman walk-behind mower covered by this page, the model number is 917.376657 (often written without the dot as 917376657). See the 917376657 owner's manual for the model/serial label location and exact identification.
How to find the model number on your mower
We recommend using the mower’s model/serial tag, not the engine cover decal.
- Look on the rear of the deck near the discharge opening
- Check the back plate area behind the engine
- Inspect the handle bracket area near the lower handle mounts
- Wipe off grass and oil film; the tag is often hard to read when dirty
- Write down both the model number and the serial number for parts matching
“6.75” vs. mower model number (quick comparison)
| What you see | What it identifies | Example | What to use for parts |
|---|---|---|---|
| 6.75 / 6.75 hp (or similar) | Engine marketing rating/series | Briggs & Stratton 625 Series | Use the mower model number first |
| Engine model/type/code | The engine itself | Stamped on engine shroud | Use for engine-only parts |
| Mower model number | The complete mower (deck, drive, handle, wheels) | 917.376657 | Use for most Craftsman mower parts |
Why it matters
Using the engine label alone can lead to the wrong blade, belt, or drive parts because multiple Craftsman decks can use similar engines. Matching parts to 917.376657 keeps fit and function correct for the cutting deck and self-propel system.
Common parts that depend on the mower model
If you are ordering wear items, the mower model number is the key.
- Blade and blade hardware (deck-specific)
- Self-propel drive parts (belt, pulleys, transmission)
- Handle and control components (cables, control bar)
For example, this model uses a 22-inch mulching blade such as the lawn mower 22-in deck mulching blade 532406713 when you are replacing the cutting blade.
