- Look for the engine model and type code on the blower housing, valve cover, or an ID label
- Compare the engine model number to the engine listing in the manual
- Use the engine model to choose the correct tune-up and fuel system parts
- If your tractor has been repowered, rely on the engine tag, not the tractor model number
What this means for parts and service
Your tractor model number identifies the chassis and mower deck parts; the engine model identifies many engine-specific parts.
| Item | Use it for | Example for 917270311 |
|---|---|---|
| Tractor model number | Deck, steering, belts, frame parts | 917270311 |
| Engine model number | Carburetor, ignition, internal engine parts | B&S 289707-1179-E1 |
Why it matters
Ordering the right maintenance and repair parts depends on matching the correct engine family. Even similar Craftsman tractors can use different engines, and the carburetor, spark plug, and gaskets can vary by engine model.

How to identify the exact engine on your 917270311
Use these quick checks to match what is actually on your tractor:
- Look for the engine ID label on the blower housing, valve cover, or near the starter
- Record the engine model, type, and code (common Briggs & Stratton format)
- Compare those numbers to the engine information listed in the specifications section
- Check whether your tractor has headlights; charging output can differ by configuration
- Verify fuel and oil specs before service (wrong oil viscosity can affect starting and wear)
Key specs you can rely on (from the manual)
These specifications apply to the tractor setup covered by the manual and are the right baseline for maintenance.
| Item | Specification |
|---|---|
| Fuel capacity/type | 1.25 gallons, unleaded regular |
| Engine oil type | SAE 30 (above 32°F), SAE 5W-30 (below 32°F) |
| Oil capacity | 3.0 pints |
| Spark plug | Champion J19LM or RJ19LM, gap 0.030 in |
| Charging system | 3 amps battery, 5 amps headlights |
Why it matters
Knowing the exact engine model helps us match the correct tune-up parts (spark plug, air filter, belts) and set the right maintenance intervals. It also prevents common issues like hard starting, poor mowing power, and premature engine wear.
Related maintenance tip
If your tractor clicks but will not crank, the starting circuit (battery connections, safety interlocks, starter solenoid) is the first place to check. The riding lawn mower engine clicks but doesnt turn over video walks through the most common causes.
