What engine does Craftsman riding mower use?
The Craftsman riding mower model 917272911 uses a 20.0 HP engine (low-emission design) with electric start and a 42-inch mower deck. For the exact engine identification details used on your tractor (label locations and specs), follow the owner's manual.
Even within the same tractor model, the most reliable way to confirm the exact engine family is to read the engine data label on the engine itself.
- Park on a level surface, set the parking brake, and remove the key.
- Let the engine cool completely before touching the muffler or cylinder area.
- Look for an engine label or stamped plate near the blower housing, valve cover, or starter area.
- Record the engine model, type, and code (or similar ID fields).
- Use that engine ID when ordering engine-specific maintenance parts.
From the Craftsman documentation for model 917272911, we can match these core specs:
| Spec | What you can expect on 917272911 |
|---|---|
| Engine output | 20.0 HP |
| Starting system | Electric start |
| Mower deck size | 42-inch |
| Transmission | 6-speed transaxle |
The engine brand and exact engine ID determine the correct tune-up parts (air filter, spark plug, fuel filter) and the right service procedures. Using the tractor model number alone is helpful, but the engine label is what prevents ordering the wrong engine-specific parts.
If you are refreshing cut quality on the 42-inch deck, these common wear items are often replaced together:
- Lawn tractor 42-in deck high-lift blade 532138971 (for lift and discharge)
- Husqvarna lawn tractor mulching blade, 21-in 532134149 (for mulching setups)
- Husqvarna lawn tractor mandrel assembly 532130794 (if you have blade wobble or bearing noise)

What model number is a Craftsman 6.75 lawn mower?
A “Craftsman 6.75” label by itself is not a single model number; it usually describes the engine horsepower class, not the mower’s model. For this page, the confirmed model number is Craftsman 917.272911, which is a 20.0 HP, 42-inch front-engine lawn tractor (not a 6.75 walk-behind mower); use the ID tag and the owner's manual to match the correct model before ordering parts.
On Craftsman equipment, the model number is typically on a product ID label, not on the engine cover.
- Check under the seat, on the frame near the rear wheels, or near the footrest area
- Look for a long number that starts with 917 on many Craftsman tractors
- Write down the full model number exactly as shown (digits and punctuation)
- Use the model number to match the correct parts diagram and part list
“6.75” is commonly used to describe an engine power class on some walk-behind mowers; it does not uniquely identify the mower.
| Marking you see | What it usually means | What to use for parts |
|---|---|---|
| 6.75 | Engine power class (not unique) | Model number from the ID label |
| 917.272911 | Equipment model number (unique) | Parts list for model 917.272911 |
Using the wrong model number can lead to ordering blades, belts, or deck parts that do not fit. For example, this tractor uses a 42-inch mower deck assembly, and common deck-related parts can include items like a blade, mandrel, or deflector shield.
For Craftsman 917.272911, you can order parts from the list for this model, or search by model number on Sears PartsDirect. If you are servicing the mower deck, examples of parts listed for this model include the lawn mower housing 548102301 (mower deck assembly) and the molded ignition key 532140403 (starting/ignition).

What year was Craftsman 917272911 made?
The Craftsman front-engine lawn tractor model 917272911 was produced during the LT2000-era, most commonly in the early-to-mid 2000s. To pinpoint the exact year for your specific tractor, use the model and serial number information shown on the tractor’s ID plate and confirm it against the identification details in the owner's manual.
We use the tractor’s ID plate information because the same model number can be produced across multiple seasons.
- Look for the model/serial number plate (commonly under the seat area or on the frame near the seat pan).
- Write down the full serial number exactly as shown.
- Check for any date code or manufacturing code printed on the label.
- Compare the label details to the identification guidance in the owner's manual.
- If the label is damaged, clean it gently and use a flashlight to read stamped characters.
The documentation we have for this unit clearly identifies the tractor as model 917272911, and it includes full parts diagrams and lists for assemblies like chassis, steering, lift, and seat. That confirms you have the correct model family for ordering parts and matching diagrams.
| What you have | What it tells you | What it does not tell you |
|---|---|---|
| Model number: 917272911 | Correct parts diagrams and compatible replacement parts | The exact production year by itself |
| Serial number (from ID plate) | The best way to narrow to a specific build period | Nothing unless you record it accurately |
The production year affects small running changes such as deck hardware, steering linkage revisions, and seat or lift components. Getting the year right helps ensure the replacement part you order matches your tractor’s exact configuration.
When you are matching parts, we recommend using the diagrams for your exact model and verifying by visual match.
- Mower deck blades (for example, lawn tractor 42-in deck high-lift blade 532138971)
- Mandrel and spindle components (for example, husqvarna lawn tractor mandrel assembly 532130794)
- Steering linkage parts
- Seat and seat switch mounting hardware
- Lift linkage and retainers

Where can I find my lawn mower engine model number?
On the Craftsman lawn tractor model 917272911, the engine model/type number is shown in the engine section of the tractor documentation; it identifies the Briggs & Stratton engine as 407677 with type 0229-E1. For the exact location of the stamping on your engine, use the diagrams in the owner's manual.
We use two reliable places to confirm the engine model information:
- Owner’s manual engine breakdown pages (fastest way to match the engine family and type)
- Engine shroud and valve cover area where Briggs & Stratton typically stamps or labels the model/type code
- Blower housing (top/front of engine) where a sticker or metal stamping is often placed
- Near the cylinder head area on V-twin engines (stamping can be on either side)
For this tractor, the manual lists the engine as a Briggs & Stratton model and type combination.
| Item | What it means | Example for 917272911 |
|---|---|---|
| Engine model number | Identifies the engine family | 407677 |
| Type number | Identifies the exact configuration | 0229-E1 |
| Tractor model number | Identifies the mower/tractor | 917272911 |
- Wipe off dirt and oil first; use a rag and mild degreaser.
- Use a flashlight and take a phone photo; zoom in to read small characters.
- Write the number exactly as shown, including dashes (for example, 0229-E1).
- If a sticker is missing, check for a stamped number on the metal nearby.
We use the engine model/type number to match the correct tune-up parts and engine-specific components (carburetor kits, gasket sets, ignition parts). Using only the tractor model number can lead to the wrong engine parts when multiple engine versions were used.
You can order tractor and deck parts for 917272911 from the parts list for this model, or search by model number on Sears PartsDirect.
