What model number is the Craftsman 42 riding mower?
For the Craftsman front-engine lawn tractor on this page, the model number is 917255981. You can confirm it on the model tag and in the owner's manual, which lists the tractor as model number 917.255981.
Where to find the model number on the tractor
We recommend checking the tractor’s identification label first, then matching it to the manual and parts list.
- Look for the model tag under the seat or seat pan area
- Check the frame near the rear fender or footrest area
- Compare the full model number (all digits) to the parts diagrams
- Use the model number when ordering belts, pulleys, steering, or electrical parts
Model number vs. deck size (42-inch)
A “Craftsman 42 riding mower” description usually refers to the cutting deck width, not a single universal model number. Many Craftsman tractors use a 42-inch deck, so the model number is what ensures correct parts fit.
| What you have | What it means | Why it matters |
|---|---|---|
| 42-inch deck | Cutting width of the mower deck | Helps narrow parts, but not enough to guarantee fit |
| Model number 917255981 | Exact tractor identification | Ensures correct belts, steering parts, and electrical parts |
| Part number | Manufacturer’s number for a part | Used to match the exact replacement |
Why it matters for parts and repairs
Using the correct model number prevents common fit issues, especially on wear items and drive components.
Common examples on this model include:
- Lawn tractor drive v-belt 532144200 for blade drive applications
- Lawn tractor lawn mower secondary v-belt 532137153 for ground drive applications
- Solenoid 532146154 if the starter circuit clicks or won’t crank

What year is my Craftsman mower serial number lookup?
On many Craftsman riding mowers, the build date is encoded in the serial number as a date code; once you identify that code on your Craftsman model 917255981, the last two digits typically indicate the year. For the exact serial number location and format used on your tractor, use the 917255981 owner's manual.
How to find the serial number on model 917255981
Look for a product ID label in one of these common spots:
- Under the seat pan (lift the seat)
- On the frame near the rear wheels
- Under the hood near the engine compartment
- Near the footrest area on the chassis rail
How to decode the “date code” (common Craftsman format)
Many Craftsman labels include a 6-digit date code that reads MMDDYY.
- MM = month
- DD = day
- YY = year
Example
If the code is 072811, that reads as July 28, 2011.
Quick check: date code vs. model number
| Item | What it tells you | What it does not tell you |
|---|---|---|
| Serial number date code | Approximate build date (month, day, year) | Engine model details, deck size, options |
| Model number (917255981) | The correct parts breakdown for your tractor | The exact build day |
Why it matters
Getting the year right helps us match the correct parts diagrams and maintenance specs for your Craftsman tractor, especially for items that change over production runs (belts, steering parts, and electrical components).

What is the average lifespan of 917255981?
A Craftsman riding lawn tractor like model 917255981 typically lasts 10 to 15 years with normal residential use and consistent maintenance. Lifespan depends most on how often you mow, storage conditions, and staying on schedule with belts, blades, oil changes, and battery care.
What most affects lifespan
- Maintenance frequency: oil changes, air filter service, lubrication, and blade care
- Drive system wear: belt condition, idler pulleys, and proper belt tension
- Operating conditions: steep hills, heavy towing, dusty mowing, and wet grass
- Storage: covered, dry storage reduces corrosion and electrical issues
- Fuel habits: fresh fuel and clean fuel system parts prevent hard-start problems
Maintenance items that commonly limit service life
Many “end of life” symptoms are really wear items that are designed to be replaced.
| Wear item | What you notice | Example part for this model |
|---|---|---|
| Drive belt | slipping, loss of ground speed | Lawn tractor drive v-belt 532144200 |
| Blade drive belt | blades slow, poor cut | Lawn tractor blade drive belt 532131264 |
| Battery and starting circuit | clicking, no crank | Solenoid 532146154 |
| Idler pulley | squealing, belt wear | Lawn tractor idler pulley 532139245 |
Why it matters
Knowing the typical 10 to 15 year lifespan helps you decide whether to invest in maintenance and key replacements (like a V-belt, idler pulley, or solenoid) versus planning for a future upgrade. Regular service also improves cut quality and reduces downtime during mowing season.
Where to confirm your maintenance schedule
We recommend following the service intervals and safety guidance in the owner's manual for Craftsman model 917255981, including the maintenance schedule, lubrication points, and storage steps.
