What engine does Craftsman riding mower use?
The Craftsman front-engine lawn tractor model 917276410 is equipped with a low-emission gasoline engine and is identified in the operator documentation as an 18.5 HP, 42-inch mower tractor. For the exact engine manufacturer and engine model details, use the identification information in the 917276410 owner's manual.
How to identify the exact engine on your tractor
We recommend confirming the engine make and model from the engine’s ID label (not just the tractor model tag). Look in these common locations:
- On the engine blower housing (top or side cover)
- Near the starter or valve cover area
- On the engine shroud close to the spark plug
- On a sticker or stamped plate near the muffler heat shield
- In the engine section of the 917276410 owner's manual
What to write down before ordering engine-related parts
Having the correct engine ID prevents wrong-part returns for tune-up and starting components.
| What to record | Example format | Why it matters |
|---|---|---|
| Tractor model | 917276410 | Confirms deck and chassis configuration |
| Engine model/type | Numbers and letters on engine label | Matches carburetor, starter, ignition parts |
| Engine code/date | Code string on label | Identifies production variation |
| Deck size | 42-inch | Matches blades, belts, mandrels |
Why it matters
Many Craftsman tractors share the same tractor model family but use different engine builds over time. The engine model number is what determines the correct starter, solenoid, ignition parts, and tune-up items.
If you are also servicing the cutting system, matching the deck components to your setup helps; for example, blade style changes performance and bagging or mulching results.

What model number is a Craftsman 6.75 lawn mower?
A Craftsman “6.75” walk-behind mower does not map to one single model number because 6.75 is an engine power rating used across many different Craftsman mowers. For the most accurate match, we use the model number from the mower’s ID label, not the engine marking.
Where to find the correct model number
Check the mower’s product ID label (not the engine shroud). Common locations include:
- Rear of the deck near the discharge chute
- Under the seat area on self-propelled models (if equipped)
- On the frame near the rear wheels
- On the handle support bracket
If you are working from a Craftsman riding tractor manual, note that this page’s documentation is for Craftsman model 917276410 (a lawn tractor), not a 6.75 walk-behind mower; see the 917276410 owner's manual.
What “6.75” usually means
On many Craftsman mowers, “6.75” refers to the engine family or horsepower class, which is shared across multiple mower models.
Quick ID checklist
Use these details to narrow the correct parts list once you have the model number:
- Deck size (often 21-inch on many Craftsman walk-behind mowers)
- Drive type (push vs. self-propelled)
- Starter type (recoil vs. electric start)
- Blade adapter style and bolt pattern
- Rear bagger vs. side discharge vs. mulching setup
Common confusion: mower model vs. engine model
| What you see | What it identifies | Best use |
|---|---|---|
| “6.75” on the engine | Engine power class | General reference only |
| Model number on mower ID label | The mower itself | Correct parts lookup |
| Engine model/type code | The engine | Engine-specific parts |
Why it matters
Using the exact mower model number prevents ordering the wrong blade, belt, air filter, or carburetor parts, since Craftsman used the same 6.75 engine rating across many different deck and drive configurations.

What year was Craftsman 917276410 made?
Craftsman model 917276410 does not have a single published “model year”; this tractor was produced and sold across multiple seasons. The most accurate way to identify your unit’s build timeframe is to use the serial number and product identification label on the tractor, then confirm specs in the 917276410 owner's manual.
How to find the build timeframe on your tractor
Use the tractor’s ID label first; it ties your exact unit to the correct parts and configuration.
- Find the model and serial number label (commonly under the seat, on the frame rail, or near the engine compartment).
- Record the model number 917276410 and the full serial number exactly as printed.
- Check for any date code on the label (some labels include a manufacture date or coded date).
- Keep the serial number handy when ordering belts, blades, steering parts, or electrical parts.
- If the engine has its own ID tag, record that too; engine date codes can help narrow the timeframe.
What the manual confirms for model 917276410
The operator’s manual verifies the configuration for 917.276410 (the same model number format with a dot).
| Manual item | What it confirms | Why it helps |
|---|---|---|
| Model number | 917.276410 | Confirms you have the correct manual family |
| Mower deck | 42-inch mower | Helps match deck parts such as blades and mandrels |
| Engine rating | 18.5 HP | Helps match tune-up and engine-related maintenance |
| Transmission | 6-speed transaxle | Helps match drive belt and linkage setup |
Why it matters
Craftsman riding mowers often have mid-series changes; the serial number is what prevents wrong-part issues on high-wear items like blades, mandrel assemblies, and the ground drive belt.
