Craftsman 247385290 lawn mower Parts

For a Craftsman 247385290 walk-behind mower, it’s cheaper to repair when the issue is routine maintenance or a small part replacement; it’s cheaper to replace when the engine or drive system needs major work or when repeated repairs keep stacking up close to the cost of a new mower.

A practical repair vs. replace checklist

• Repair if it needs a tune-up item (spark plug, air filter, fresh fuel, blade service).
• Repair if the mower runs but cuts poorly (often a dull or damaged blade).
• Repair if the fix is a single, visible deck or handle part (cracked cover, broken knob).
• Replace if the engine has low compression, heavy smoking, or persistent overheating.
• Replace if it has severe vibration after impact and the deck or crankshaft is damaged.
• Replace if multiple systems are failing (starting, cutting, and wheel/height adjustment).

What the manual says to check first (low-cost fixes)

Your 247385290 owner’s manual points to several common, inexpensive causes before you assume a major failure:

Symptom	Often caused by	Typical low-cost action
Won’t start	Stale fuel, not primed, faulty spark plug	Drain/refill with fresh gas, prime correctly, replace spark plug
Runs rough	Dirty air cleaner, gas cap vent plugged	Clean/replace air filter, clear/replace cap
Excessive vibration	Loose or bent blade	Tighten blade hardware, replace blade
Won’t mulch well	Wet or overly tall grass, dull blade	Mow dry grass, raise cut height, sharpen/replace blade

Parts that commonly make repair worthwhile

If the mower is otherwise in good shape, replacing a worn cutting or discharge component is usually a smart repair:

• Craftsman troybilt lawn mower 21-in deck mulching blade 942-0741A if the blade is dull, bent, or unbalanced.
• Side discharge components if clippings are not directing properly.
• Control and handle hardware if operation feels unsafe or inconsistent.

Why it matters

A mower that vibrates, has a damaged blade, or has worn discharge shielding can become unsafe and can also damage the engine over time. The manual also calls out stopping the engine and disconnecting the spark plug wire after striking an object, then repairing damage before operating again.

Common problems on the Craftsman 247385290 walk-behind gas mower are no-start or hard-start conditions, poor cutting quality, excessive vibration after hitting debris, and discharge or mulching issues caused by buildup or worn cutting parts. Our first checks are always fuel, oil level, and blade condition using the 247385290 owner's manual.

Quick checks we do first (fastest wins)

• Confirm the engine has fresh gasoline and the correct oil level (these mowers ship without oil or gas).
• Make sure the spark plug wire is firmly connected.
• Inspect the blade for bends, cracks, or heavy wear; replace if damaged.
• Check for grass buildup under the deck and around the discharge area.
• Verify the trail shield and chute area are intact and positioned correctly.

Most common symptoms and likely causes

Symptom	Most likely causes	What to do next
Won’t start / hard to start	Old fuel, dirty carburetor, fouled spark plug, low oil	Drain old fuel, add fresh fuel, service ignition and fuel system per the manual
Excessive vibration	Blade damage from striking an object, loose hardware	Stop engine, disconnect spark plug wire, inspect and repair before using
Poor cut (uneven)	Cutting height mismatch, dull blade	Set wheel height levers evenly; sharpen or replace blade
Clippings clump or don’t mulch well	Wet grass, grass too tall, deck packed with clippings	Avoid wet grass; bag if over 4 inches; clean deck

Parts that commonly get damaged or wear out

If you’re seeing vibration, poor cut, or discharge problems, these model-matched parts are frequent fixes:

• Craftsman troybilt lawn mower 21-in deck mulching blade 942-0741A (dull, bent, or nicked blade)
• Mtd lawn mower side chute deflector 731-07486 (broken or missing discharge control)
• Lawn mower control cable 946-04661 (blade control issues at the handle)

Why it matters

A walk-behind mower that vibrates, cuts poorly, or won’t start is often telling you something is unsafe or damaging the engine or deck. Catching blade damage, fuel issues, and grass buildup early prevents bigger repairs and improves cut quality.
