Craftsman 247370100 lawn mower Parts

The most common issues we see on the Craftsman 247370100 walk-behind mower are starting problems, poor cutting quality, and discharge or mulching performance issues. These usually trace back to routine wear items, deck buildup, or control and chute components needing adjustment or replacement; use the 247370100 owner's manual for model-specific checks.

Common symptoms and what they usually mean

• Won’t start or starts then dies: stale fuel, dirty air filter, fouled spark plug, or carburetor varnish
• Cuts unevenly or leaves strips: dull/bent blade, loose blade adapter, incorrect cutting height, worn wheels
• Clumps grass or won’t mulch well: wet/overgrown grass, packed deck, mulching door not closing fully
• Grass blows out the side or chute won’t stay positioned: damaged chute, weak hinge/bracket, missing fasteners
• Blade won’t spin normally or vibration: blade damage, adapter wear, loose hardware (stop mowing until checked)

Parts on this model that commonly wear

These are frequently involved when the mower’s cut or discharge changes:

• Craftsman troybilt lawn mower 21-in deck mulching blade 942-0741A
• Mtd lawn mower blade adapter 748-0376E
• Lawn mower discharge chute assembly 931-04486A
• Mtd lawn mower zone control cable 946-0957
• Kmart lawn mower wheel 734-04562

Quick checks we recommend (safe, fast)

1. Shut off the engine, disconnect the spark plug wire, and let the muffler cool.
2. Tip the mower with the air filter and carburetor side up (prevents fuel and oil issues).
3. Scrape packed grass from the underside of the deck and around the discharge opening.
4. Inspect the blade for dull edges, bends, and cracks; tighten mounting hardware.
5. Confirm the cutting height is set evenly on both sides.

Symptom-to-fix guide

Symptom	Most likely cause	Typical fix
Uneven cut	Blade dull, height mismatch	Sharpen/replace blade; level height
Poor mulching	Deck packed, mulching door issue	Clean deck; check door/spring
Side discharge problem	Chute damage or misalignment	Replace chute/hinge parts
Engine stops when handle released	Zone control cable out of adjustment	Adjust or replace cable

Why it matters

A sharp, secure blade and a clean deck reduce engine load, improve cut quality, and help prevent vibration that can damage the crankshaft and deck components over time.

A Craftsman walk-behind gas mower like model 247370100 typically lasts 8 to 12 years with normal residential use and routine maintenance. Lifespan depends most on engine care, blade impacts, deck corrosion, and how consistently you service wear items listed in the owner's manual.

What affects lifespan the most

• Oil changes and clean oil level (biggest factor for engine life)
• Air filter and spark plug upkeep (easy, high impact)
• Blade strikes (rocks, roots) that stress the crankshaft and blade adapter
• Deck rust and corrosion from wet grass storage
• Wheel and height adjuster wear from rough terrain and frequent adjustments

Typical lifespan by usage pattern

Usage pattern	What we see most often	Expected lifespan
Light (small yard, weekly in season)	Lower hours, fewer impacts	10 to 12 years
Average (typical suburban yard)	Normal wear items replaced	8 to 10 years
Heavy (large yard, rough ground)	More vibration and deck wear	6 to 8 years

Maintenance that adds years (and prevents costly failures)

• Change engine oil on schedule; never run low
• Keep the underside of the deck clean and dry after mowing
• Replace a bent or badly worn blade; for this model, a common wear item is the 21-in deck mulching blade 942-0741A
• Inspect the discharge area and safety shielding; replace damaged pieces such as the side chute deflector 731-07486
• Check fasteners and controls for looseness; vibration accelerates wear

Why it matters

Most “mower won’t start” and “poor cut quality” complaints come from basic maintenance and impact damage, not the mower being “worn out.” Keeping the blade system straight and the engine serviced is what gets you to the 10 to 12 year range.
