Where to look on a Craftsman riding mower
- Lift the seat and look for a metal or adhesive model plate on the frame
- Write down the model number and serial number exactly as shown
- If the plate is dirty, wipe it clean so every digit is readable
- Take a photo of the plate for reference when ordering parts
Tractor model number vs. engine model number
Your tractor and engine use different model numbers. For model 917251550:
| What you’re identifying | Where it’s located | Why it matters |
|---|---|---|
| Tractor model number (917251550) | Plate under the seat | Ensures the correct Craftsman parts diagrams and parts list |
| Engine model number | On the engine blower housing | Helps match engine-specific parts like filters and carburetor components |
Why it matters
Using the correct model number prevents ordering the wrong parts for your Craftsman front-engine lawn tractor, especially for items that vary by build such as belts, switches, and steering or ground drive components.
Helpful next step

What kind of oil do you use in a Craftsman lawn tractor?
For the Craftsman lawn tractor model 917251550, use SAE 10W-30 4-cycle engine oil for temperatures above 32°F, and SAE 5W-30 for temperatures below 32°F (API SF/SG). This viscosity match helps protect the engine during both hot mowing and cold starts; see the owner's manual for the full viscosity chart and service intervals.
Oil type and temperature chart
Use this quick guide for your engine oil selection:
| Outside temperature | Recommended oil | Notes |
|---|---|---|
| Above 32°F (0°C) | SAE 10W-30 | Best for typical mowing-season temps |
| Below 32°F (0°C) | SAE 5W-30 | Helps with easier cold-weather starting |
How much oil does it take?
Your 917251550 engine oil capacity is:
- With oil filter: 4.2 pints
- Without oil filter: 3.7 pints
If you are doing an oil change with a filter, we recommend replacing the filter at the same time; the oil filter 12-050-01-s1 listed for this model is a common maintenance item.
Tips for choosing and using the right oil
- Use 4-cycle (4-stroke) engine oil (not 2-cycle mix).
- Choose oil that meets API SF/SG performance listed for this tractor.
- Check oil level on level ground before each use.
- Do not overfill; fill only to the FULL mark on the dipstick.
- For seasonal temperature changes, switch viscosity (10W-30 to 5W-30) to match conditions.
Why it matters
Correct oil viscosity reduces wear on internal engine parts, improves lubrication at startup, and helps control operating temperature. Using the right oil for the weather is one of the simplest ways to extend the life of a Craftsman riding mower engine.

What year did Craftsman make the 917251550?
Craftsman model 917251550 was produced in multiple runs; the model number alone does not identify a single build year. The reliable way to get the exact year for your tractor is to read the product ID label and match it to the specifications and parts breakdown in the 917251550 owner's manual.
How to find the exact build year on your tractor
Check the tractor itself first, then use the manual to confirm what you have.
- Locate the product ID label (commonly under the seat, on the frame rail, or near the rear fender pan).
- Write down the serial number and any date code printed on that label.
- Check the engine identification tag; the manual shows a Kohler CV22-PS67515 configuration for this model.
- Compare your tractor’s deck and chassis to the illustrated parts sections to confirm the configuration.
- If the label is missing or unreadable, use distinctive parts (PTO switch style, wiring layout, deck hardware) to narrow the production version.
Model-specific identifiers we can confirm
The documentation for this Craftsman tractor ties these details directly to model 917.251550.
| What to check | What you should see for 917251550 | Why it helps |
|---|---|---|
| Manual model listing | 917.251550 | Confirms you are using the correct book |
| Engine family shown | Kohler CV22-PS67515 | Helps match engine tag details |
| Parts sections | Chassis, engine, mower deck | Helps verify the exact configuration |
Why it matters
The build year and production version affect parts fit, especially for electrical and drive components. For example, a no-start or no-crank issue often traces to the PTO circuit; matching your switch style to the correct replacement (such as the switch 582107601) prevents ordering the wrong part.
