Where can I find my lawn mower engine model number?
On the Craftsman 917289106 riding lawn tractor, the engine model number is typically stamped into the metal on the engine itself (often on the blower housing, valve cover area, or near the cylinder head). Use the locations shown in the owner's manual to confirm the exact spot for your tractor and engine.
Where to look on the engine
Check these common engine ID locations (wipe dirt and grass off first):
- Top or side of the cylinder head area (stamped into metal)
- Blower housing or engine shroud (sticker or stamped plate)
- Valve cover area (near the top of the engine)
- Near the starter or flywheel screen
- Frame rail near the engine (sometimes a secondary label)
What the number looks like (and what to record)
We recommend writing down all identifiers you find, because parts lookups often need more than one number.
| What to capture | Why it matters |
|---|---|
| Engine model number | Identifies the exact engine family and spec |
| Type/spec code | Narrows down carburetor, ignition, and charging parts |
| Code/date (if present) | Helps match production changes |
Why it matters
The tractor model number (917289106) identifies the mower and deck system, but the engine model number identifies engine-specific parts like ignition components, starter parts, and fuel system items. Having both prevents ordering the wrong part.
If the tractor will not start while you are checking
Follow basic safety steps first: set the parking brake, turn the key to STOP, and remove the key before working around the engine. If you are diagnosing a no-start, common causes include a weak battery, corroded terminals, loose wiring, or a faulty solenoid.
- Clean and tighten battery terminals
- Inspect wiring connections at the starter/solenoid
- Check for a solid click at the solenoid when turning the key
- Verify the ignition switch is functioning
If you determine the solenoid is faulty, the lawn tractor starter solenoid 582042802 is a common replacement part for this model.

What model number is a Craftsman 917289106 lawn mower?
The model number is 917.28910 (often written without the dot as 91728910) for the Craftsman front-engine lawn tractor covered by this parts list. Your full tractor model identifier may also include a product prefix like 917289106, so we recommend matching the number on the ID tag to the owner's manual.
Where to find the model number on the tractor
Look for the model/product identification label in one of these common spots:
- Under the seat (seat pan area)
- On the rear fender near the seat
- On the frame rail near the engine
- Near the footrest area on the chassis
- Under the hood area on the frame
How the numbers relate (917.28910 vs 917289106)
Craftsman riding equipment often shows a shorter model plus a longer product number. Both can be useful when ordering parts.
| What you see | Example | What it means | When to use it |
|---|---|---|---|
| Model number (manual format) | 917.28910 | The tractor model shown in the operator’s manual | Manuals, general specs, many parts lookups |
| Model number (no dot) | 91728910 | Same model number, different formatting | Parts lookup and searches |
| Product number / full identifier | 917289106 | A longer identifier tied to the exact build/configuration | Best for exact parts matching |
Why it matters
Using the exact model/product number helps us match the correct deck parts, belts, and electrical components for your tractor, such as a ground drive belt, blades, or an ignition switch.
Parts you may commonly match by model number
If you are confirming fitment for maintenance items, these are examples of parts listed for this model page:
- Lawn tractor ground drive or blade drive belt 592855201 (belt routing and length must match)
- Lawn tractor ignition switch 532193350 (keyed switch style varies by build)
- Lawn tractor starter solenoid 582042802 (starting circuit components vary by configuration)

What year was Craftsman 917289106 made?
Craftsman model 917289106 (LT2000 series) was produced across multiple years, so there is not one single “made year” tied to that model number alone. The exact build date is identified on the tractor’s product/serial number label (commonly under the seat) and is sometimes referenced in the documentation for your unit in the owner's manual.
How to find the exact year on your tractor
Use the tractor’s ID label to pin down the manufacturing date for your specific unit.
- Park on a level surface, set the parking brake, and remove the key
- Lift the seat and look for the product/serial number label (often on the fender pan under the seat)
- Write down the model number and serial number exactly as shown
- Check the date code or manufacturing information printed on that label
- Match the information to the identification section in the owner's manual
What “917289106” tells you (and what it does not)
The model number identifies the product family and configuration (LT2000-style front-engine lawn tractor), but it does not uniquely encode a single calendar year.
| Identifier | What it’s used for | What it helps you do |
|---|---|---|
| Model number (917289106) | Finds the correct parts diagrams and parts list | Ensures belts, blades, electrical parts, and chassis parts match |
| Serial number | Identifies your specific tractor | Helps determine the exact build date and production run |
Why it matters
The production year can affect small design changes such as deck hardware, belt routing, and electrical connectors. Confirming the build date helps you choose the right maintenance and replacement parts, such as a deck belt or blade.
Common parts that vary by deck setup
If you are ordering parts, confirm your deck configuration first.
- Deck drive belt options can differ by routing and length (example: lawn tractor ground drive or blade drive belt, 1/2 x 92-2/5-in 592855201)
- Blade style can vary by cutting preference (mulching vs high-lift)
- Spindle and mandrel components can vary by deck revision (example: lawn tractor mandrel housing 587819701)
