What model number is a Craftsman 247384380 lawn mower?
The model number for this Craftsman walk-behind mower is 247384380. On Craftsman mowers, the model number is the best way to match the correct operator instructions and ensure you order the right replacement parts for your exact deck and handle configuration; see the 247384380 owner's manual.
Where to find the model number on the mower
We typically see the model number on an ID label or tag in one of these spots:
- On the rear of the deck near the discharge opening
- On the top of the deck near the engine mounting area
- On the rear skirt area behind the engine
- On the handle support or lower handle bracket
Model number vs. manual model listing (why it can look different)
Some Craftsman operator manuals list a model family and note that the last digit can vary. That is normal for 21-inch mower platforms, and your full model number (247384380) is still the correct identifier to use for parts lookup and service.
| What you see | What it means | What to use for parts |
|---|---|---|
| 247384380 | Your exact mower model | 247384380 |
| 247.38438* | Model family shown in some manuals | 247384380 |
Why it matters
Using the exact model number helps prevent ordering the wrong blade, chute, or handle hardware, and it also ensures maintenance steps (like cutting height adjustment and blade service) match your mower’s setup.

Where is the serial number on a Craftsman lawnmower?
On most Craftsman walk-behind mowers like model 247384380, the model and serial number label is typically on the rear of the mower deck, near the lower handle mounting points. Use the label to match the correct parts list and the correct operating instructions in the 247384380 operator’s manual.
Where to look on the mower
Check these common label locations first (starting with the most likely):
- Back of the deck, between or just below the lower handle mounts
- Rear discharge opening area (near the trail shield/rear skirt)
- Top of the deck near the engine mounting area (less common)
- Side of the deck near the height adjuster brackets (less common)
Tips for finding a hard-to-see label
If the sticker is dirty or faded, these steps usually help:
- Wipe the area with a damp rag, then dry it
- Use mild soap and water; avoid harsh solvents that can remove printing
- Shine a flashlight across the surface at a low angle to make faint text stand out
- Take a close-up photo and zoom in to read worn characters
What you should write down (and why it matters)
Record both numbers exactly as shown.
| Item | What it’s used for | Why it matters |
|---|---|---|
| Model number | Identifies the mower version | Ensures diagrams and parts match your deck and handle setup |
| Serial number | Identifies the production run | Helps confirm the correct revision when parts changed mid-series |
Why it matters
Craftsman walk-behind mowers often have multiple close model variations; using the correct model and serial number helps us match parts like the grass catcher, discharge chute, and blade components to your exact deck configuration.

What is the average lifespan of 247384380?
The Craftsman 247384380 walk-behind mower has an average useful life of 7 years or about 140 hours of operation when maintained and used normally. After that point, we recommend a yearly inspection to keep mechanical and safety systems working correctly (see the 247384380 owner's manual).
What “7 years or 140 hours” means in real use
How quickly you reach 140 hours depends on your mowing habits.
- 1 hour/week for a 6-month season: about 26 hours/year (about 5 to 6 seasons)
- 2 hours/week for a 6-month season: about 52 hours/year (about 2 to 3 seasons)
- Larger yards, heavy mulching, or frequent bagging can add hours faster
- Poor storage (old fuel, moisture) shortens service life
| Usage pattern | Hours per year (typical) | Time to reach 140 hours |
|---|---|---|
| Light | 20 to 30 | 5 to 7 years |
| Moderate | 40 to 60 | 2 to 4 years |
| Heavy | 70 to 100 | 1 to 2 years |
Maintenance that most affects lifespan
Consistent maintenance is what keeps a gas mower reliable year after year.
- Change engine oil on schedule
- Keep the air filter clean
- Use fresh fuel and stabilize fuel for storage
- Keep the underside of the deck clean to prevent corrosion and poor cutting
- Replace worn cutting parts (a dull blade strains the engine)
Why it matters
Past the average useful life, wear on safety and drive components becomes more likely. A yearly inspection helps prevent hard starting, poor cut quality, and unsafe operation.
