What year is my Craftsman mower serial number lookup?
For Craftsman model 917287131, the year is not determined by the model number alone. You typically identify the year by reading the date code embedded in the serial number on the tractor’s product label, then converting that code into a calendar date.
Where to find the serial number on model 917287131
We usually see the serial/product label in one of these spots on a front-engine lawn tractor:
- Under the seat (lift the seat pan)
- On the frame near the rear wheels
- On the underside of the hood or near the dash tower
- Near the engine compartment on the chassis rail
For label locations and tractor identification details, use the 917287131 operator's manual.
How the serial number date code is commonly formatted
Many Craftsman-built tractors use a 6-digit date code within the serial number that reads as:
- MMDDYY (month, day, year)
Example
| Date code | Interprets as | Build date |
|---|---|---|
| 072811 | MMDDYY | July 28, 2011 |
If your serial number includes a different pattern (letters mixed in, more digits, or multiple number groups), the “year” may be encoded differently.
Quick checklist to decode it correctly
- Write down the full serial number exactly as shown (include letters)
- Look for a 6-digit group that could be MMDDYY
- Confirm the “month” is 01-12 and the “day” is 01-31
- If multiple 6-digit groups exist, use the one closest to “SERIAL” or “S/N”
Why it matters
Knowing the build year helps us match the right Craftsman parts and specs for your 917287131, especially for wear items like mower blades, belts, and electrical switches.

What kind of engine does a Craftsman riding lawn mower have?
The Craftsman riding lawn mower model 917287131 is equipped with a low-emission, internal combustion gasoline engine rated at 20.0 HP by the engine manufacturer. For the exact engine make/model used on your tractor, we recommend checking the engine ID label and the 917287131 operator's manual.
What we can confirm for model 917287131
From the model-specific specifications in the manual, this tractor uses:
- Gasoline engine (unleaded regular fuel)
- 20.0 HP rating (as rated by the engine manufacturer)
- Electric start system
- 6-speed transaxle drivetrain
- Spark plug type: Champion RC12YC (0.030 in gap)
Where to find the exact engine brand and model
On riding mowers like the Craftsman 917287131, the tractor model number identifies the tractor platform, but the engine model is typically identified on the engine itself.
Check these common locations:
- Valve cover or blower housing label
- Engine shroud near the recoil area (if equipped)
- Sticker near the spark plug wire
- Stamped tag near the muffler or fuel tank side
Once you have the engine model/type code, you can match tune-up items (spark plug, air filter, fuel filter) more accurately.
Quick spec snapshot (model 917287131)

What kind of oil do you use in a Craftsman lawn tractor?
For the Craftsman lawn tractor model 917287131, we use high-quality detergent 4-cycle engine oil rated API SG-SL: SAE 30 when operating above 32°F, and SAE 5W30 when operating below 32°F. See the oil chart in the 917287131 owner's manual.
Oil type and temperature guide
Use the viscosity that matches your typical mowing temperature.
| Outside temperature | Recommended oil (engine) |
|---|---|
| Above 32°F (0°C) | SAE 30 |
| Below 32°F (0°C) | SAE 5W30 |
Oil capacity for model 917287131
This model lists different capacities depending on whether an oil filter is installed.
- With oil filter: 56 oz
- Without oil filter: 48 oz
Tips for choosing and using the right oil
- Use detergent oil meeting API SG-SL.
- If you run 5W30 above 32°F, check the oil level more often; multi-viscosity oils can increase oil consumption in warmer temps.
- Check oil on level ground and keep the level up to (but not over) the FULL mark.
- Change engine oil about every 50 hours of operation or at least once a year.
Why it matters
Correct oil viscosity helps the engine stay lubricated at startup and protected under load. Using the wrong viscosity can increase wear, cause hard starting in cold weather, or lead to low-oil operation if consumption increases.
