How old is my lawn mower by serial number?
To estimate the age of your Craftsman walk-behind mower model 247374320, we use the serial number from the model and serial tag, then match its date code format to the manufacturer’s build date chart shown in the 247374320 owner's manual. This gives you the mower’s approximate manufacture date.
Where to find the serial number
On most Craftsman walk-behind mowers, the model and serial tag is a sticker or metal plate located on the deck or rear housing.
Check these common spots:
- Top of the mower deck near the engine mount
- Rear of the deck near the discharge opening or rear door
- Near the height-adjustment brackets by a rear wheel
- On the handle support area close to the deck
How to decode the serial number (what to look for)
Serial numbers typically include a date code (often embedded as digits that represent year and week, or year and month). Once you have the full serial number, compare its pattern to the examples in the manual.
Use this quick checklist:
- Write down the full serial number exactly as shown
- Look for a 2-digit year (YY) or 4-digit year (YYYY)
- Look for a week number (01 to 52) or a month indicator
- Confirm the format matches the manufacturer style shown in the manual
Quick guide: common date-code patterns
These are the most common formats we see on walk-behind mowers; your exact format depends on the manufacturer that built the Craftsman unit.
| What you see in the serial | Usually means | Example interpretation |
|---|---|---|
YYWW embedded in serial |
Year + week of year | 2315 = week 15 of 2023 |
YYYYMM embedded in serial |
Year + month | 202104 = April 2021 |
| Letter + numbers | Plant/line + date code | Use manual examples to match |
Why it matters
Knowing the build date helps us match the correct parts and diagrams for your mower, especially for wear items like the blade, wheels, control cable, and grass bag.

How to read a Craftsman mower serial number?
On many Craftsman walk-behind mowers (including model 247374320), the serial number is used to identify the manufacturing date and production run; a common format is MMDDYY (month, day, year). For the exact location and format used on your mower’s tag, use the 247374320 owner's manual.
Where to find the serial number on a walk-behind mower
We typically see the serial number on the mower’s ID label in one of these spots:
- Rear of the deck near the discharge opening or rear door
- Top of the deck near the engine mounting area
- On the rear frame crossbar behind the engine
- Near the height-adjuster area on the deck side
- On a label near the handle mount points
How to interpret the date code (common Craftsman format)
A very common Craftsman date-code pattern is:
| Serial number segment | Meaning | Example |
|---|---|---|
| First 2 digits | Month (01 to 12) | 07 = July |
| Next 2 digits | Day (01 to 31) | 28 = 28th |
| Last 2 digits | Year (00 to 99) | 11 = 2011 |
If your serial number begins with 072811, that reads as July 28, 2011.
Quick checks so you do not misread the tag
Before you decode it, we recommend these quick checks:
- Confirm you are reading the serial number, not the model number (247374320)
- Look for letters mixed in; letters often indicate a plant code or revision, not the date
- Write the number down exactly as shown, including leading zeros
- If the mower has multiple labels, use the one that lists both model and serial
Why it matters
The serial number helps match the correct Craftsman parts diagrams and revisions (blade, wheels, control cable, bagging parts) so you order parts that fit the exact production version of your mower.

What are the common problems with Craftsman lawn mowers?
Common problems on the Craftsman walk-behind mower model 247374320 usually come down to starting issues, poor cutting, and bagging or discharge problems. We see these most often when routine maintenance is overdue or when wear parts (blade, cables, wheels, chute) are damaged or loose; check the 247374320 owner's manual for the correct operating and maintenance steps.
Most common symptoms and what they usually mean
- Won’t start or starts then dies: stale fuel, dirty spark plug, clogged air filter, or carburetor varnish
- Hard to pull the starter rope: blade obstruction, seized blade adapter, or engine internal resistance
- Cuts unevenly or leaves strips: dull/bent blade, deck packed with wet grass, uneven wheel height
- Poor bagging or clumping: clogged deck, torn bag, wrong mowing speed for conditions
- Vibration or rattling: loose blade hardware, damaged blade adapter, bent blade
Quick checks we recommend first (5 to 10 minutes)
- Turn the fuel valve on (if equipped) and use fresh gasoline; drain old fuel if it smells sour.
- Inspect the blade area for packed grass and debris; clean the underside of the deck.
- Confirm the cutting height is set evenly on both sides.
- Check that the side discharge chute is installed and moving freely.
- Look for obvious looseness at the wheels and handle mounting points.
Parts that commonly affect performance on this model
If you’re seeing a specific symptom, these model-matched parts are often involved:
| Symptom | Likely area | Example model-matched part |
|---|---|---|
| Poor bagging, clumps | Bagging system | Lawn mower grass bag 964-04154 |
| Grass blowing out the side | Side discharge | Mtd lawn mower side chute deflector 731-07486 |
| Uneven cut, scalping | Wheels/height | Rear wheel (11-in) or wheel hardware |
| Vibration | Blade/blade mount | Mulching blade or blade adapter |
Why it matters
Most “common problems” are really performance symptoms caused by fuel quality, blade condition, and deck airflow. Fixing those basics first prevents repeat issues and helps the mower cut cleaner with less strain on the engine.

What model number is the Craftsman 247374320?
The model number for this Craftsman walk-behind lawn mower is 247374320. You’ll find it on the mower’s model and serial number label; matching that number in the 247374320 owner's manual helps ensure you get the right parts and service information.
Where to find the model number on the mower
Most Craftsman walk-behind mowers place the model/serial label in one of these spots:
- On the rear of the deck near the bagging opening
- On the top of the deck near the engine mount area
- On the rear frame or handle bracket area
- Near the height-adjustment area on the deck side
Why the exact model number matters
Craftsman mowers often have similar names (like “M210”), but parts can vary by deck design, handle hardware, and bagging or mulching setup. Using 247374320 helps us match the correct diagrams and parts list for your mower.
Common examples of parts that can differ by model
- Mulching blade style and center hole pattern
- Grass bag and frame fitment
- Side chute deflector shape and hinge points
- Control cable length and end fittings
Quick check: model number vs. part numbers
| What you’re looking at | Example format | What it’s used for |
|---|---|---|
| Model number | 247374320 | Identifies the mower |
| Part number | 942-0741A | Identifies a replacement part |
| Serial number | Varies | Production run tracking |
Helpful next step
If you’re confirming fitment for bagging parts, compare your setup to the diagrams in the manual and the parts list. For example, the lawn mower grass bag 964-04154 is a common replacement item on this model.
Why it matters
A one-digit mismatch in the model number can lead to ordering a blade, cable, or bagging component that does not mount correctly, even if it looks similar.
