What kind of engine does a Craftsman riding lawn mower have?
For Craftsman model 917288100, the operator’s manual identifies it as a lawn tractor with a low-emission gasoline engine; horsepower and engine brand vary by configuration, but this model is rated at 20.0 HP (as rated by the engine manufacturer). For exact engine details, use the 917288100 owner’s manual.
How to identify the exact engine on model 917288100
Use these quick checks to match the engine type and service parts:
- Look for the engine ID label on the blower housing or valve cover (model, type, code).
- Compare the engine label to the specifications section in the manual.
- Confirm whether your tractor has electric start and automatic transmission (both are listed for this model).
- Check the air filter and spark plug style; they often differ by engine family.
- If you are ordering deck-related parts, confirm your deck size; this model is shown with a 42-inch mower deck.
What we know from the manual (model-specific)
| Item | What to expect on 917288100 |
|---|---|
| Engine type | Low-emission gas engine |
| Power rating | 20.0 HP (manufacturer-rated) |
| Starting | Electric start |
| Drive | Automatic transmission |
Why it matters
The exact engine make and model controls the correct tune-up parts (spark plug, air filter, fuel filter) and the right maintenance specs. It also helps when troubleshooting starting issues or poor performance.
If you are focused on mowing performance rather than engine service, blade choice also matters; a high-lift blade improves bagging and discharge in many conditions, while a mulching blade is better for fine clippings.

What year was Craftsman 917288100 made?
The Craftsman lawn tractor model 917288100 is commonly associated with the mid-2000s era, and it aligns with the Craftsman 917.28810 series shown in the operator documentation. For the most accurate build timeframe for your exact tractor, match the product/serial information to the 917288100 owner's manual.
How to pinpoint the exact year for your specific tractor
Because model families can span multiple production runs, the most reliable way to date your tractor is by using the identification information on the machine.
- Locate the model and serial number label (commonly under the seat, on the frame rail, or near the engine compartment)
- Write down the full serial number exactly as shown
- Compare the label details to the identification guidance in the 917288100 owner's manual
- If your tractor has an engine model/type/code label, record that too (it often helps narrow the production date)
- Keep the numbers with your maintenance records for future parts lookups (belts, blades, filters)
What we can confirm from the documentation
The operator documentation identifies this tractor as a Craftsman lawn tractor in the 917.28810 model series with a 42-inch mower deck and electric start.
| Item | What it tells you | What it does not tell you |
|---|---|---|
| Model number family (917.28810 / 917288100) | Product series and parts platform | Exact build year by itself |
| Serial number | Best indicator of production timing | Nothing unless you record it |
| Engine code | Often date-coded by engine maker | Tractor assembly date may differ |
Why it matters
The exact year affects parts and service details such as deck configuration, belt routing, blade style, and electrical components. For example, if you are servicing the cutting deck, using the correct blade type and hardware helps prevent vibration and uneven cutting; see options like the lawn tractor 42-in deck high-lift blade 532138971 when you are matching deck parts.

Where can I find my lawn mower engine model number?
On your Craftsman lawn tractor model 917288100, the engine model number is printed on an engine ID label or stamped into the engine shroud. The quickest way to find it is to remove the hood (if needed) and look on top of the engine cover and along the side of the blower housing. For model-specific safety and access steps, use the 917288100 owner's manual.
Where to look on the engine
Check these common locations first (clean the area if it is dusty or oily):
- Top of the engine cover (shroud) near the recoil housing or air screen
- Side of the blower housing (often easiest to see from the right side)
- Valve cover area or nearby flat metal surface with a stamped code
- Under the hood near the engine mounting area (label may face the frame)
- Near the muffler heat shield (label can be on an adjacent shroud panel)
What to write down (and why)
Most small engines use multiple identifiers. Record everything exactly as shown.
| What you see on the engine | What it’s used for | Example format |
|---|---|---|
| Model number | Identifies the engine family | 12Axxx-xxxx |
| Type / trim code | Narrows down parts variations | Type 0xxx |
| Code / date | Helps match the correct revision | YYMMDDxx |
Tips to make the label readable
- Turn the key off, remove the key, and let hot parts cool.
- Wipe the label area with a rag; use a soft brush for packed grass.
- Use a flashlight and take a phone photo, then zoom in.
- If the label is missing, look for stamped numbers on metal shrouds.
Why it matters
The tractor model number 917288100 identifies the chassis and deck, but the engine model number is what we use to match engine-specific parts like the starter, carburetor, ignition coil, and air filter.

Who makes Craftsman push mower engines?
Craftsman uses engines from multiple small-engine manufacturers; the maker depends on the specific mower and the engine model stamped on the engine. For Craftsman model 917288100 (a front-engine lawn tractor, not a push mower), use the 917288100 owner's manual to locate the engine identification and follow the correct maintenance specs.
How to tell who made the engine (works for push mowers and riding tractors)
Use the engine’s ID, not the mower or tractor model number:
- Look for a brand badge on the engine shroud (common makers include Briggs & Stratton, Kohler, and Kawasaki).
- Find the engine model and type code on a label or stamped metal (often on the blower housing, valve cover, or near the muffler).
- Write down the full engine model, type, and code before buying tune-up parts.
- Match parts like the air filter, spark plug, and fuel filter to the engine model.
- If the label is missing, clean the shroud and check multiple sides of the engine for a stamped code.
What applies to Craftsman 917288100
The 917288100 operator manual covers safe operation and routine service for this riding lawn tractor, including where to find engine identification and how to set up maintenance intervals.
Quick ID checklist
| What you have | Where to look for engine ID | What the ID helps you choose |
|---|---|---|
| Push mower | Engine shroud or valve cover label | Air filter, spark plug, carb parts |
| Riding lawn tractor (917288100) | Engine shroud or valve cover label | Oil spec, tune-up parts, service settings |
Why it matters
The engine manufacturer and engine model number determine the correct service parts and specs (oil type, plug gap, air filter style), which prevents hard starting, surging, and premature engine wear.
