How old is my mower by serial number?
To estimate the age of your Craftsman gas walk-behind mower model 917377823, we use the serial number from the ID decal on the rear of the mower housing, then match that serial format to the manufacturer’s date code. The quickest first step is finding and recording that serial exactly as shown in the 917377823 owner’s manual.
Where to find the serial number on model 917377823
The model and serial numbers are printed on a decal located on the rear of the lawn mower housing.
- Tip the mower only as directed in the manual (avoid fuel spills)
- Wipe dirt and grass off the rear deck area so the decal is readable
- Write down the model number and serial number exactly (including any letters)
- Record the date of purchase if you still have it (receipt, warranty card, or service record)
- Take a clear photo of the decal for reference
How serial numbers translate to “age”
Most walk-behind mowers do not show the build date in plain text; the date is typically embedded in the serial number as a manufacturer code.
| What you have | What it tells you | Best use |
|---|---|---|
| Serial number | Manufacturing date code (varies by maker) | Best way to estimate mower age |
| Date of purchase | When you bought it (not always build date) | Helpful for warranty and maintenance history |
| Model number 917377823 | Identifies the correct parts and diagrams | Needed to match the right lookup method |
Practical ways to narrow down the mower’s age
- Compare the serial number format to the identification section in the 917377823 owner’s manual
- If the decal includes a “date of purchase” field that was filled in, use that as a reliable baseline
- If you have service paperwork, the earliest service date is a strong clue to the mower’s minimum age
- If you are stocking maintenance items, follow the tune-up guidance in how to tune up a lawn mower video
Why it matters
Knowing the mower’s age helps us match the correct Craftsman parts (like a drive cable, blade adapter, or wheel hardware), plan maintenance intervals, and decide when wear items should be replaced versus adjusted.

What are the most common issues with 917377823?
The most common issues we see on the Craftsman 917377823 gas walk-behind lawn mower involve starting and running problems, weak self-propel drive, poor cutting quality, and wheel or handle hardware loosening over time. Use the maintenance and adjustment steps in the 917377823 owner's manual to confirm the correct settings and service intervals.
Common symptoms and what they usually point to
- Won’t start or starts then dies: stale fuel, dirty air filter, fouled spark plug, or carburetor varnish
- Runs rough or surges: partially clogged carburetor, restricted fuel flow, or governor linkage out of adjustment
- Self-propel won’t pull: stretched/misadjusted drive cable, worn drive components, or a slipping belt/pulley
- Cuts uneven or leaves strips: dull/bent blade, deck packed with wet grass, or blade adapter wear
- Wheel wobble or poor traction: worn wheel parts, missing clips/e-rings, or loose fasteners
Quick checks we recommend first (fast and safe)
- Drain old fuel and refill with fresh gasoline (use the correct fuel type noted in the manual).
- Inspect and replace the spark plug if it’s dark, oily, or the electrode is worn.
- Clean the underside of the deck (with the spark plug wire disconnected).
- Verify the blade is tight and the blade adapter is not rounded or cracked.
- Check cable free-play and engagement; a loose cable often causes weak drive.
Parts that commonly wear on this model
These parts are often involved when the symptoms above show up:
| Symptom | Part to inspect | What failure looks like |
|---|---|---|
| Engine won’t shut off or must hold bail tightly | Lawn mower zone control cable 532191221 | Cable frayed, kinked, or out of adjustment |
| Self-propel weak or intermittent | Lawn mower drive cable 583180101 | Excess slack, stretched housing, broken end |
| Uneven cut, blade won’t stay tight | Lawn mower blade adapter 532421176 | Rounded drive tabs, wobble at blade mount |
| Wheel play/noise | Lawn mower e-ring 812000058 | Missing/loose retainer, wheel shifting on axle |
Why it matters
Small issues like a stretched cable or worn blade adapter reduce cutting performance and can accelerate wear on the drive system, wheels, and deck hardware. Catching them early keeps the mower safer and more reliable.
