How to read Craftsman serial number?
On Craftsman lawn tractor model 247270390, the serial number is primarily used to identify the exact production run for parts lookup and Smart Lawn App setup. The most reliable way to interpret it is to match the serial number format shown on the product label and in the owner's manual.
Where to find the serial number (and why it matters)
You typically need the serial number when ordering the correct replacement parts, checking compatibility for attachments, or pairing the mower to the Smart Lawn App.
Common places to check:
- Under the seat on the frame or seat pan
- On the rear frame near the hitch plate
- Near the engine compartment on the chassis rail
- On a barcode label used for Smart Lawn App entry
How Craftsman serial numbers are commonly formatted
Craftsman riding mower serial numbers are not all identical across years and factories. Some units use a date-coded pattern (often interpreted as month, day, year), while others use a plant and sequence format.
Use this quick guide to decide what you have:
- If the serial begins with 6 digits that look like a date, it is often read as MMDDYY.
- If the serial includes letters mixed with numbers, it is usually a manufacturing code plus a sequence number.
- If your label shows barcodes for model and serial, enter them exactly as printed for the best match.
Quick comparison
| What the serial looks like | What it usually means | Best next step |
|---|---|---|
| 6 digits (example: 072811) | Often a date code (MMDDYY) | Confirm against label format in the manual |
| Letters + numbers | Factory/line code + sequence | Use it for parts lookup and app pairing |
| Two barcodes (model and serial) | Scan/enter for Smart Lawn | Enter both values exactly |
Smart Lawn App note (model and serial are both used)
For Smart Lawn features, the operator manual explains that the app prompts you to enter the mower’s model number and serial number barcodes and then connects via Bluetooth when the key is in the ON position or the engine is running. The serial number is used to identify your specific unit during setup.
Why it matters
Serial number format affects how you interpret the digits and helps prevent ordering the wrong Craftsman or MTD-style parts for your exact 247270390 configuration.

What are common problems with Craftsman riding mowers?
Common problems on a Craftsman riding mower like model 247270390 usually fall into a few buckets: it will not start or cranks slowly, it starts but runs poorly or overheats, the cut quality is uneven or it vibrates, or the deck will not mulch well. Our owner's manual troubleshooting chart and maintenance schedule help pinpoint the cause fast.
Most common symptoms and what typically causes them
- Clicks but will not crank: weak battery, loose cables, or a failing starter solenoid
- Cranks but will not start: stale fuel, dirty air filter, fouled spark plug, or fuel delivery issue
- Runs rough or hesitates: dirty air cleaner, spark plug gap issue, or restricted airflow
- Overheats: low engine oil level or debris packed around cooling fins and blower housing
- Vibration or poor cut: loose/unbalanced blade, bent/dull blade, deck out of level, or uneven tire pressure
Quick checks we recommend first (in order)
- Oil level: check before each use; low oil can damage the engine.
- Air intake and cooling: clear grass and debris from the engine cooling fins and blower housing.
- Air filter and spark plug: replace common tune-up items if they are dirty or worn.
- Blade condition: tighten, balance, sharpen, or replace if bent or dull.
- Tire pressure: match pressures side-to-side to prevent an uneven cut.
Parts that commonly solve these problems
| Problem area | Common fix | Example part for model 247270390 |
|---|---|---|
| No-start or clicking | Replace solenoid | Lawn tractor starter solenoid 725-06153 |
| Runs rough, lacks power | Replace air filter | Lawn & garden equipment engine air filter KH-32-883-09-S1 |
| Hard starting, misfire | Replace spark plug | Spark plug KH-25-132-12-S |
| Poor mulching or vibration | Replace blade | Mtd lawn tractor 46-in deck mulching blade 942-04268 |
Why it matters
Most “big” mower problems start as simple maintenance issues. Keeping oil at the correct level, maintaining airflow (clean filter and cooling fins), and keeping blades sharp prevents overheating, stalling, uneven cutting, and premature wear on the PTO and drive components.
Helpful DIY guidance
If your symptom is specifically a no-crank or click condition, follow riding lawn mower engine clicks but doesnt turn over video for a step-by-step diagnostic path.

What model number is the Craftsman 247270390 riding mower?
The model number for this Craftsman riding mower is 247270390. In the operator documentation, this tractor is part of the 247.27039* model series (the asterisk indicates related variants in the same family); use the exact number on your ID tag for parts and manual matching.
Where to find the model number on the tractor
We use the model number and serial number together to match the correct parts list (blade, air filter, solenoid) and the right operating instructions.
- Check the product ID label under the seat or near the frame by the engine
- Write down both the model and serial numbers
- If your label shows a dot format (example: 247.27039), match it to 247270390 for ordering
- Use the barcode entry option if you are pairing with the Smart Lawn app
Model number formats you may see
The same mower family can be printed a few different ways depending on the label or manual.
| Where you see it | Example format | What it means |
|---|---|---|
| Parts listing and ordering | 247270390 | Exact model used for this parts page |
| Operator’s manual series | 247.27039* | Model family; includes close variants |
| ID label | 247.27039XXX | Variant suffix; use the full label when possible |
Why it matters
Using the exact model number prevents ordering the wrong maintenance parts and hardware, especially on items that vary by deck and engine configuration (for example a 46-in blade set, throttle cable routing, or electrical connectors).
Helpful next steps
- Confirm your maintenance intervals and specifications in the owner's manual
- If you are doing a tune-up, common items for this model include the spark plug and engine air filter
- For cutting performance issues, inspect the deck blade condition and tire pressure before adjusting the deck

What riding mower has the least problems?
If you want the fewest problems, choose a well-built riding mower with a proven engine and a hydrostatic transmission, then keep up with routine maintenance. For owners comparing brands, Kubota and John Deere are widely regarded as top reliability picks; within Craftsman, your best results come from following the maintenance and operating guidance in the 247270390 owner's manual.
What “least problems” usually means
Most “problem-free” experiences come down to fewer breakdown-prone systems and better upkeep.
Common reliability factors:
- Hydrostatic transmission (smoother drive, fewer shift-linkage issues)
- V-twin engine (typically smoother, less vibration than many single-cylinder designs)
- Easy-to-service air filter and spark plug access
- Proper deck setup (level deck, correct tire pressure)
- Correct mowing habits (avoid overloading the deck)
How to pick a mower that stays reliable
When you compare lawn tractors and zero-turn mowers, focus on build and serviceability more than marketing features.
Quick comparison
| What you prioritize | Best fit | Why it tends to have fewer issues |
|---|---|---|
| Long-term durability, heavy use | Premium lawn tractor | Heavier frames and drivetrains, better component life |
| Fast mowing around obstacles | Zero-turn mower | Fewer passes, but more drive system complexity |
| Lowest maintenance | Electric rider | No fuel system or oil changes; battery health becomes the key |
Keeping your Craftsman 247270390 trouble-free
Your Craftsman 247270390 is designed for normal residential grass (up to about 10 inches). Avoiding overload and keeping the engine tuned prevents many “mower problems” that are really maintenance issues.
Start with these high-impact items:
- Replace the spark plug on schedule (a worn plug can cause hard starting and poor idle); use spark plug KH-25-132-12-S
- Keep the intake clean; replace the lawn & garden equipment engine air filter KH-32-883-09-S1
- Run at proper engine speed when mowing and mulching; slow RPM causes poor cut quality
- Keep blades sharp and balanced; replace if bent; consider the mtd lawn tractor 46-in deck mulching blade 942-04268
- Level the deck and keep tire pressure even to prevent uneven cutting
Why it matters
Most “least problems” decisions are really “least downtime” decisions. A mower with a solid drivetrain plus consistent tune-ups (air filter, spark plug, blades, deck leveling) avoids the most common no-start, rough-running, vibration, and poor-cut complaints.
