Do Craftsman mowers use Briggs and Stratton engines?
Yes, many Craftsman mowers and lawn tractors use Briggs & Stratton engines, and Craftsman model 917270771 specifically lists a Briggs & Stratton engine model 42E707 (type 2631-E1) in the parts and repair sections of the 917270771 owner's manual.
What this means for parts and service
When your Craftsman 917270771 has a Briggs & Stratton engine, engine-related maintenance and repair parts are typically identified by the Briggs engine model and type number (not just the tractor model number).
Common engine service items you will match by engine model/type include:
- Air filter and pre-cleaner
- Spark plug and ignition parts
- Fuel filter and fuel line fittings
- Carburetor kits and gaskets
- Starter and charging system components
Quick ID checklist (use this before ordering)
Use these identifiers together to avoid ordering the wrong engine part:
- Tractor model: 917270771
- Engine brand: Briggs & Stratton
- Engine model: 42E707
- Engine type: 2631-E1
Tractor parts vs. engine parts (simple guide)
| You are replacing | Usually matched by | Example areas |
|---|---|---|
| Mower deck and cutting parts | Tractor model 917270771 | Blades, mandrels, deck belts |
| Drive and chassis parts | Tractor model 917270771 | Ground drive belt, steering, wheels |
| Engine internal or fuel/ignition parts | Briggs engine model/type | Carburetor, gaskets, ignition |
If you are working on the cutting system, a common deck-related replacement is the husqvarna lawn tractor mandrel assembly 532130794.
Why it matters
Briggs & Stratton built multiple versions of similar engines; the model and type number determine the exact carburetor, gasket set, and ignition parts that fit. Using the correct identifiers saves time and prevents repeat repairs.

How much oil does a Craftsman 917270771 take?
The Craftsman lawn tractor model 917270771 typically takes about 2 quarts (64 oz) of engine oil when you do an oil change and then top off to the full mark on the dipstick. For the exact fill amount for your Briggs and Stratton engine (42E707, type 2631-E1), use the specs in the 917270771 owner’s manual.
How we recommend filling it (most accurate method)
- Park on level ground and set the parking brake.
- Warm the engine 2 to 3 minutes, then shut it off and let it sit 1 minute.
- Drain oil completely; replace the drain plug/valve securely.
- Add about 1.5 quarts, wait 30 seconds, then check the dipstick.
- Add oil in small amounts until it reaches the FULL mark.
- Do not overfill; stop exactly at the full line.
Oil capacity quick guide
| Service situation | Typical amount to add | Final check |
|---|---|---|
| Drain and refill (common) | ~2.0 qt (64 oz) | Dipstick at FULL |
| If you changed an oil filter (if equipped) | Slightly more than 2.0 qt | Dipstick at FULL after a brief run |
Why it matters
Correct oil level protects the crankshaft, piston rings, and valve train. Low oil causes rapid wear; overfilling can make the engine smoke, leak, or run poorly.
Helpful related maintenance
- Use the viscosity listed in the manual for your temperature range.
- Check oil before each mow during heavy use.
- If the tractor starts smoking after an oil change, recheck for overfill.

What model number is the Craftsman 917270771 engine?
The Craftsman lawn tractor model 917270771 uses a Briggs & Stratton engine model 42E707 with type number 2631-E1. You will see this listed in the engine breakdown for this tractor; use these numbers when ordering engine-specific parts.
Where to find the engine model and type on the tractor
We recommend confirming the numbers on the engine ID label so you match the exact engine build.
- Look for a metal tag or sticker on the engine shroud, valve cover area, or blower housing
- Record both the model (42E707) and type (2631-E1)
- Also note the code number (a date code) if it is shown
- Match the engine label to the engine section in the 917270771 owner's manual
Why the “type number” matters
Briggs & Stratton uses the type number to identify the exact configuration (carburetor, governor linkages, muffler, charging system). Two engines can share the same model number but use different parts if the type number differs.
| What to capture | Example for this tractor | Used for |
|---|---|---|
| Engine model | 42E707 | Base engine family |
| Type number | 2631-E1 | Exact parts match |
| Code (date) | Varies | Production changes |
Related parts you might replace during engine or deck service
If you are doing a tune-up or chasing vibration and cut quality issues, these common mower-deck parts are often serviced at the same time (separate from the engine model ID):
- Inspect blades for bends, cracks, and dull edges
- Check belt condition for glazing, cracking, or stretching
- Spin mandrels by hand; replace if noisy or loose
- Verify pulleys turn freely and do not wobble
Helpful examples for this model include the husqvarna lawn tractor mulching blade, 21-in 532134149 and the lawn tractor drive belt 532144200.
Why it matters
Using the correct engine model and type prevents wrong-part returns and saves time, especially for ignition, fuel, and exhaust components that vary by engine configuration.
