- Rear of the deck near the discharge opening or rear door area
- Side of the deck near a wheel height adjuster
- Near the engine mounting area on the deck (less common)
What the label looks like and what to copy
The label usually includes multiple identifiers. Copy them exactly as shown.
- Model number (example format: 917.370872 or 917370872)
- Serial number (unique to your mower)
- Product number or other manufacturing codes (if shown)
Quick ID checklist
| Item | What it’s used for | Why it matters |
|---|---|---|
| Model number | Parts lookup and diagrams | Ensures correct fit for blades, belts, wheels |
| Serial number | Production variation | Helps match the right revision of parts |
| Engine model/type/code | Engine parts | Needed for spark plug, air filter, carburetor parts |
Why it matters
Craftsman walk-behind mowers can look similar across multiple model numbers, but parts like the blade, drive belt, and transmission components can differ. Using the exact model number helps us match the correct diagrams and compatible parts the first time.

What are the common problems with Craftsman lawn mowers?
On the Craftsman 917370872 walk-behind mower, the most common problems are no-start conditions (fuel, spark, or control-bar issues), loss of drive from dirty or worn drive-wheel components, poor cutting from a worn or loose blade, and performance problems caused by grass buildup under the deck. See the 917370872 owner's manual for the model-specific troubleshooting chart and maintenance steps.
Most common symptoms and what usually causes them
- Won’t start: dirty air filter, stale fuel or water in fuel, spark plug wire off, bad spark plug, control bar not held down, weak battery (if equipped)
- Loss of power: cutting too much grass, dirty air filter, grass and debris packed under the deck, walking speed too fast
- Excessive vibration: worn, bent, or loose blade; broken blade adapter; bent crankshaft
- Hard to push or drive slows: drive wheels not turning freely due to grass and debris; worn drive components
Quick checks we recommend first (safe, fast, and common)
- Confirm the control bar is held against the handle while starting (the engine brake must release).
- Check fuel quality: if fuel is old, drain and refill with fresh gasoline.
- Inspect the spark plug lead: make sure the wire is firmly connected.
- Look under the deck (engine off, spark plug wire removed): remove packed grass and leaves.
- Check the drive wheels: if they do not spin freely, clean debris from the dust cover, pinion, and gear teeth.
Parts that commonly wear on this model
| Problem you see | Part that often fixes it | What it affects |
|---|---|---|
| Poor cut, vibration | Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 | Cut quality and balance |
| Mower won’t self-propel or slips | Lawn mower ground drive belt 532196853 | Drive engagement |
| Drive wheel binds or skips | Lawn mower wheel dust cover 581840401 | Keeps debris out of wheel drive |
Why it matters
Catching these issues early prevents unsafe vibration, protects the engine from overload (especially when grass builds up under the deck), and keeps the self-propel system from wearing out faster.
