What kind of engine does a Craftsman riding lawn mower have?
The Craftsman riding lawn mower model 917271061 uses a 15.5 HP gas engine with electric start (as listed in the model’s documentation). For the exact engine make and model (such as Briggs & Stratton and the engine model number), we recommend matching the engine ID label to the specifications in the 917271061 owner's manual.
How to identify the exact engine on model 917271061
Use these quick checks to confirm what you have before ordering tune-up parts:
- Look for the engine ID label on the blower housing, valve cover, or near the starter
- Record the engine model, type, and code (or spec number)
- Compare those numbers to the engine information listed in the manual
- If the label is missing, use the tractor model number 917271061 plus the engine’s physical features (air filter style, carburetor layout) to narrow it down
- Keep the engine numbers with your maintenance records for future parts lookups
What the manual tells us about this tractor’s engine setup
The documentation for Craftsman 917271061 confirms key engine-related specs used for operation and maintenance.
| Spec item | What to expect on 917271061 |
|---|---|
| Horsepower rating | 15.5 HP |
| Starting system | Electric start |
| Fuel type | Unleaded regular gasoline |
| Oil viscosity (typical) | SAE 10W30 above 32°F; SAE 5W-30 below 32°F |
Why it matters
The engine brand and exact engine model determine the correct spark plug, air filter, oil filter, and some fuel system parts. Using the tractor model alone is not always enough for engine tune-up parts, so confirming the engine ID prevents wrong-part returns and hard-start issues.

What are the parts of a tractor engine?
On the Craftsman tractor model 917271061, the engine is a Kohler CV15.5S (Type 41596); its main engine systems include the fuel system, ignition/electrical, crankcase, and lubrication components, along with external items like the throttle control and muffler. For the exact illustrated breakdown, use the 917271061 owner's manual.
Major engine systems (what they include)
These are the core “groups” you will see in the engine parts diagrams for this model:
- Fuel system: carburetor-related parts, fuel line, hose clamps, fuel filter
- Ignition and electrical: flywheel, stator, ignition module, spark plug, kill/ground lead
- Crankcase and breather: crankcase hardware and sealing surfaces
- Oil pan and lubrication: oil pan components and lubrication-related parts
- Exhaust: muffler and related mounting hardware
Common engine parts you may replace
Many repairs on a riding mower engine involve service parts and bolt-on components rather than internal machining.
- Spark plug
- Fuel filter
- Carburetor repair kit or gaskets
- Throttle control linkage items
- Muffler (this model lists an exhaust muffler)
If you are replacing the muffler on this tractor, match it to the exact listing for exhaust muffler 532159420.
Quick reference: engine “parts list” examples for this model
| Engine area | Example parts you may see listed | What it does |
|---|---|---|
| Fuel system | Fuel line, fuel filter, carburetor kit | Delivers and meters fuel to the engine |
| Ignition/electrical | Stator, ignition module, spark plug | Creates spark and charges the battery |
| Exhaust | Muffler | Reduces noise and routes exhaust |
| Controls | Throttle control | Sets engine speed and choke for starting |
Why it matters
Knowing the engine system (fuel vs. ignition vs. lubrication) helps you troubleshoot faster. For example, a no-start often points to fuel delivery or ignition parts, while smoking or low power can point to air/fuel mixture, exhaust restriction, or maintenance issues.

Who makes Craftsman lawn mower engines?
For the Craftsman 917271061 front-engine lawn tractor, Craftsman-branded tractors commonly use engines supplied by major small-engine manufacturers such as Briggs & Stratton, Kohler, or Kawasaki; the exact engine maker for your unit is identified on the engine ID label and in the 917271061 owner's manual.
How to identify the engine manufacturer on your tractor
Use the engine’s model and type code (on the engine itself) to confirm who made it.
- Lift the hood and locate the engine ID label (often on the blower housing, valve cover, or near the starter)
- Write down the engine brand plus the model/type/code numbers
- Match those numbers to the engine maker’s lookup (Briggs & Stratton, Kohler, or Kawasaki)
- Cross-check the engine information against the specifications section in the 917271061 owner's manual
- If the label is missing or unreadable, use the tractor’s build information and parts diagrams to narrow it down
What we can confirm for model 917271061 from the manual
The manual confirms the tractor configuration (15.5 HP, electric start, 42-inch mower deck, automatic transmission), which is consistent with engines sourced from the common suppliers above.
Quick reference: where to look
| What you need | Where to find it | Why it helps |
|---|---|---|
| Engine brand name | Printed on the engine shroud/cover | Identifies the manufacturer immediately |
| Engine model/type/code | Engine ID label or stamped tag | Needed for correct tune-up and parts |
| Tractor model number 917271061 | Tractor frame tag | Helps match the correct manual and diagrams |
Why it matters
The engine manufacturer determines the correct spark plug, air filter, oil filter, and tune-up procedure. Using the engine’s exact model/type/code prevents ordering the wrong maintenance parts and helps troubleshooting (no-start, hard-start, or stalling) go faster.

What year did Craftsman make the 917271061?
Craftsman model 917271061 is commonly identified as a 1991 Craftsman LT1000-series lawn tractor (often listed as 1991-03 in parts/diagram catalogs). For confirmation tied to your exact tractor configuration, match the model and key assemblies in the 917271061 owner's manual.
How to confirm the build timeframe on your specific tractor
We recommend verifying using identifiers that stay with the machine, since tractors can be sold across seasons.
- Check the product identification label (typically under the seat or on the frame near the rear fender pan).
- Compare your engine family and spec tag to what your tractor uses.
- Match chassis and enclosure parts diagrams to your tractor’s layout.
- Verify deck and lift components match the illustrated assemblies.
- Use the manual parts lists to confirm major assemblies (chassis, engine, lift, wheels).
Quick reference: what we can verify from the manual vs. what indicates the year
| Item | What it tells you | Where to look |
|---|---|---|
| Model number 917271061 | Confirms the exact Craftsman model family | Tractor ID label; manual cover/parts sections |
| Engine model/spec | Helps narrow production window and correct tune-up parts | Engine tag on Kohler engine |
| Parts diagrams (chassis/engine/lift) | Confirms configuration used on your tractor | Manual illustrated parts lists |
Why it matters
Knowing the correct year range helps you order the right maintenance and repair parts (belts, blades, mandrel parts, steering parts) and prevents mismatches when Craftsman used similar model numbers across LT-series tractors.
