What model number is the Craftsman 247889981?
The model number is 247.889981 (often written without the dot as 247889981) for this Craftsman gas walk-behind mower. You can confirm it on the model and parts identification pages in the 247889981 owner's manual.
Where to find the model number on the mower
Most Craftsman walk-behind mowers place the model tag in one of these spots:
- On the rear of the deck near the discharge chute
- On the deck housing near the engine mounting area
- On the frame near the rear wheels
- On a label near the handle mounting brackets
Model number vs. engine model number (common mix-up)
This mower has a separate engine model number used for engine-specific parts (spark plug, air filter, carburetor parts). The mower model number identifies the deck, drive system, wheels, handle, and controls.
| What you’re identifying | Example from this mower’s documentation | Used for |
|---|---|---|
| Mower model number | 247.889981 | Deck, blade, wheels, drive belt/cable, handle parts |
| Engine model number | 219807-3712-G5 | Engine tune-up and internal engine parts |
Why it matters
Using the correct model number prevents ordering the wrong blade, belt, or hardware. For example, this model uses a 33-inch deck system, so parts like the blade must match that deck size.

What are the most common issues with 247889981?
The most common problems we see on the Craftsman 247889981 walk-behind mower are drive and blade system wear (belt, pulleys, cables), cutting issues (dull or damaged blade, deck buildup), and fuel-related no-start symptoms. Use the owner's manual for model-specific adjustments and maintenance intervals.
Common symptoms and what usually causes them
- Mower will not self-propel or drive is weak: worn or stretched drive belt, idler pulley wear, or a cable out of adjustment
- Blade will not engage or cuts unevenly: blade timing belt issues, mandrel wear, or a bent/dull blade
- Excess vibration: damaged blade, loose fasteners, or mandrel bearing wear
- Poor cut quality or clumping: deck packed with wet grass, blade dull, or deck housing damage
- Hard starting or stalling: stale fuel, restricted fuel flow, or dirty air filter (maintenance item)
Quick checks we recommend first
- Disconnect the spark plug wire before inspecting under the deck.
- Tip the mower safely (most walk-behinds: air filter and carburetor side up) and clear packed grass.
- Inspect the blade for bends, cracks, and heavy nicks.
- Check belt condition for glazing, cracking, or slack.
- Verify control cables move freely and return fully.
Parts that commonly solve these issues (when worn)
If your symptoms match, these model-listed parts are frequent fixes:
| Symptom | Likely wear item | Example part on this model |
|---|---|---|
| No/weak drive | Belt or idler pulley | Belt, 1/2 x 72-1/2-in 954-04139 or lawn mower idler pulley 753-08171 |
| Blade not engaging, timing off | Blade timing belt | Mtd lawn mower blade timing belt, 3/4 x 50-7/8-in 754-04136 |
| Vibration, noise at spindle | Mandrel assembly | Lawn mower mandrel assembly 918-04439C |
| Poor cut, tearing grass | Deck blade | Mtd lawn mower 33-inch deck 2-in-1 blade 942-04154A |
| Drive or blade control feels wrong | Control cable | Lawn mower clutch cable kit 946-04609 or lawn mower brake control cable, left 946-04608 |
Why it matters
Catching belt, pulley, blade, and mandrel wear early prevents bigger damage to the deck housing and improves cut quality, safety, and drive performance.

What is the average lifespan of 247889981?
A Craftsman walk-behind mower like model 247889981 typically lasts 10 to 15 years with normal residential use and routine maintenance. The engine’s emissions durability guidance in the owner's manual also aligns with roughly a decade-plus of typical homeowner run time.
What determines lifespan on this mower
The biggest drivers are annual run hours, storage, and how consistently you maintain the engine and drive system.
- Annual usage (most walk-behind mowers run about 20 to 25 hours per year)
- Oil changes and correct oil level
- Clean air filter and fresh fuel practices
- Blade condition and deck cleanliness
- Belt and pulley wear in the drive and blade system
- Rust prevention and dry, covered storage
Practical lifespan ranges (what most owners see)
| Usage pattern | Typical outcome | What to focus on |
|---|---|---|
| Light (small yard, good storage) | 12 to 15 years | Fuel care, corrosion prevention |
| Average (typical homeowner) | 10 to 12 years | Oil changes, blade sharpening |
| Heavy (large yard, dusty conditions) | 7 to 10 years | Air filtration, belts, frequent service |
Maintenance that extends life the most
These are the highest-impact items we recommend staying on top of:
- Change engine oil on schedule; never run low
- Keep the cutting system balanced; replace a bent or badly worn blade such as the Mtd lawn mower 33-inch deck 2-in-1 blade (part number 942-04154A)
- Inspect and replace worn drive components like the Mtd lawn & garden equipment belt, 1/2 X 72-1/2-in (part number 954-04139) when slipping starts
- Keep cables adjusted so the blade brake and drive engage fully
- Clean grass buildup under the deck to reduce corrosion and load
Why it matters
A mower that is maintained to last 10 to 15 years starts easier, cuts cleaner, and avoids premature wear on high-cost assemblies (blade drive, pulleys, and mandrel components). Following the service intervals and specs in the owner's manual is the fastest way to protect the engine and cutting deck.
