How to look up Craftsman model number?
For a Craftsman riding lawn tractor like model 917276181, we look up the model number by finding the model and serial tag on the tractor (most often under the seat area) and then using that exact number when searching parts and manuals, such as the 917276181 owner's manual.
Where to find the model and serial number tag
On most Craftsman front-engine lawn tractors, the identification tag is typically located in one of these spots:
- On the frame under the seat
- On the underside of the seat
- Near the rear fender area around the seat pan
- On the frame rail near the engine compartment (less common)
How to use the model number to look up parts
Once you have the model number, match it exactly (including all digits). For example, 917276181 points you to the correct diagrams and parts lists for this tractor.
- Enter the full model number when searching
- Use the parts diagrams to confirm the exact part name and location
- Match the part by description and fit, not just by appearance
- Keep the serial number handy for production-date variations
Example: model number vs. part identifiers
| What you have | Example | What it’s used for |
|---|---|---|
| Model number | 917276181 | Finds the correct tractor parts breakdown |
| Part ID | 587819701 | Identifies a specific Sears PartsDirect part listing |
| Part number | 187281 | Manufacturer number used across listings |
Why it matters
Using the exact Craftsman model number prevents ordering the wrong belt, blade, or electrical part. Even similar-looking 42-inch deck tractors can use different mandrel housings, pulleys, or wiring harnesses depending on the model series.

What engine does Craftsman riding mower use?
For Craftsman lawn tractor model 917276181, the operator’s manual identifies it as a low-emission, 20.0 HP riding lawn tractor with a 42-inch mower deck; the manual does not call out a specific engine brand in the excerpted specs. For exact engine make and model, use the engine identification label and the 917276181 owner's manual.
How to identify the exact engine on your tractor
Use these checks to confirm the engine manufacturer and model family on your specific unit:
- Look for the engine ID label on the blower housing, valve cover, or near the starter
- Record the model, type, and code (common on Briggs & Stratton) or the model/spec (common on Kohler)
- Match the ID to the engine parts list section in the manual
- Compare the tractor’s model number 917276181 and serial information to the manual’s identification guidance
- If the label is missing, check for a stamped ID on the engine shroud or tag bracket
What we can confirm from the 917276181 manual
The manual for this tractor describes these key powertrain and deck characteristics:
| Item | What to expect on 917276181 | Where to confirm |
|---|---|---|
| Engine output class | 20.0 HP (low-emission design) | 917276181 owner's manual |
| Deck size | 42-inch mower deck | 917276181 owner's manual |
| Starting | Electric start | 917276181 owner's manual |
| Transmission | Automatic transmission | 917276181 owner's manual |

Getting the exact engine make and model right ensures you buy the correct tune-up and repair items (air filter, spark plug, fuel filter, starter solenoid) and follow the correct oil and maintenance specs for your engine.
Related part that often comes up with engine starting issues
If the engine clicks or struggles to crank, the starting circuit is a common place to inspect; one model-matched part to consider is the lawn tractor starter solenoid 582042802.

What engine oil for Craftsman lawn mower?
For the Craftsman lawn tractor model 917276181, we use SAE 10W-30 for most conditions; the engine ships from the factory filled with summer-weight oil, and you should always verify the correct viscosity and capacity in the 917276181 owner's manual.
Recommended oil type and when to use it
Most 4-cycle riding mower engines run best on detergent automotive oil that meets current API service ratings.
- SAE 10W-30: best all-around choice for typical spring through fall mowing
- SAE 30 (summer-weight): good for consistently warm temperatures
- 5W-30: best for cold-weather starting (early spring or late fall)
- Use 4-cycle engine oil only (never 2-cycle mix)
- Check oil on level ground and do not overfill
Quick oil selection guide
| Outdoor temperature | Oil viscosity to use | Why it helps |
|---|---|---|
| Below ~40°F | 5W-30 | Easier cold starts, faster lubrication |
| ~40°F to ~100°F | SAE 10W-30 | Strong protection across changing temps |
| Consistently hot weather | SAE 30 | Stable viscosity in heat |
How to check and top off oil (safe, fast steps)
Follow the dipstick method described in the manual.
- Park the tractor on a flat surface and let the engine cool
- Remove the oil fill cap/dipstick, wipe it clean
- Reinsert fully, then remove and read the level
- Add oil to reach the FULL mark (do not overfill)
- Reinstall the cap/dipstick securely before starting
Why it matters
Correct oil viscosity protects the engine from heat and wear, improves starting, and helps the tractor maintain consistent power under load (especially when mowing at full throttle).

What model number is a Craftsman 6.75 lawn mower?
A Craftsman “6.75” walk-behind mower is identified by the model number printed on its model tag, not by the 6.75 rating. If you are looking at our Craftsman riding tractor documentation, the operator manual shown is for model 917.27618 (model family 917276181). Use the model tag on your mower to match the exact number.
Where to find the model number on a Craftsman 6.75 mower
On most Craftsman 21-inch walk-behind mowers, the model tag is on the mower deck or rear housing. Look for a sticker or metal plate that lists Model and sometimes Product Number.
- Check the rear of the deck near the discharge opening
- Check the top of the deck near the engine mounting area
- Check behind the bagger door (if equipped)
- Wipe dirt and grass off the tag so all digits are readable
- Write the full model number exactly as shown (including dots or dashes)
Don’t confuse “6.75” with the model number
“6.75” is a power rating used on some mower engines; it is not unique to one Craftsman mower. Multiple Craftsman mowers can share that rating but use different blades, belts, and wheels.
| What you see | What it means | What to use for parts |
|---|---|---|
| 6.75 | Engine power rating | Model number from the tag |
| 917.xxxxxxx | Craftsman model format | Exact 917 number |
| 42" / 20.0 HP | Tractor specs (riding models) | Tractor model number |
If you are actually working on Craftsman model 917276181 (tractor)
For the Craftsman front-engine lawn tractor model 917276181, we use the operator documentation for setup, operation, and troubleshooting. Start with the 917276181 owner's manual.
Why it matters
The correct model number ensures you get the right maintenance parts (like blades, belts, and electrical components) and prevents ordering a part that fits a different deck size or drive system.

What year did Craftsman make the 917276181?
Craftsman model 917276181 is identified in the documentation as Model No. 917.27618 (a 20.0 HP, 42-inch deck, electric start, automatic transmission lawn tractor). The exact build year is typically determined from the tractor’s product ID/serial label; use the 917276181 owner's manual to confirm the label location and identification details.
How to find the exact year on your tractor
We use the product ID/serial label to match your specific production run. Check these common locations:
- Under the seat pan or on the seat bracket
- On the rear fender pan near the seat
- On the frame rail near the engine
- Near the transaxle area on the frame
- Under the hood along the chassis
What the model number tells you (and what it does not)
The model number narrows you to the correct parts and manual, but the serial/product number is what pins down the manufacturing date.
| Identifier | Example you may see | What it’s used for |
|---|---|---|
| Model number | 917276181 (or 917.27618) | Correct parts lists, deck size family, manual match |
| Serial/product number | Varies by unit | Production date and factory run identification |
Why it matters
Getting the year right helps us match the correct configuration for wear items and assemblies that can change mid-series, such as blades, belts, and deck hardware. For example, if you are servicing the 42-inch mower deck, common deck components include the lawn tractor mandrel housing 587819701 and the correct blade style for your cutting setup.
Quick tips when ordering parts for 917276181
- Match by model number + serial/product number, not model alone
- Verify deck size (42-inch) before buying blades or belts
- Replace worn hardware (lock nuts, clips) when removing pulleys or mandrels
- If the cut is uneven, check deck level and blade condition before replacing major parts
