Is it cheaper to repair or replace a lawn mower?
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.
- 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).
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 |
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.
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.

What are the common problems with Craftsman lawn mowers?
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.
- 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.
| 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 |
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)
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.

How do I find the model number on my 247385290?
The model number for your Craftsman walk-behind mower is printed on the model tag; on this series it appears as 247.38529 (often shown with a dot) and corresponds to 247385290 for parts lookup. Use the identification section in the 247385290 owner's manual to match the tag format.
Check these common model-tag locations on Craftsman 21-inch walk-behind mowers:
- On the rear of the deck near the discharge opening or rear skirt
- On the top of the deck near the engine mounting area
- Near the height-adjuster area by a rear wheel
- On the handle bracket area (lower handle mounts)
Model tags can show punctuation or extra characters. Use these tips so you get the right parts.
- Write the model exactly as shown on the tag first
- If you see 247.38529, enter it as 247385290 when searching parts
- Ignore spaces; keep the digits in order
- If the tag is dirty, wipe it with a damp rag and mild detergent, then dry it
| On the tag | Use for parts lookup |
|---|---|
| 247.38529 | 247385290 |
Craftsman model numbers identify the exact deck, handle, and blade-control setup; that is what ensures parts like the control cable, mulching blade, or side chute fit correctly and install without modification.
