What year did Craftsman make the 917272950?
Craftsman model 917272950 was produced during the LT1000-era of Craftsman front-engine lawn tractors (commonly late 1990s through mid-2000s). For the exact build year of your specific tractor, use the product identification information shown in the Craftsman 917272950 owner's manual.
How to find the exact year for your tractor
We use the tractor’s identification label information to pin down the production date for a specific unit.
- Look for the model and serial number label (commonly under the seat, on the frame, or near the rear fender area).
- Write down the full serial number exactly as shown.
- Compare the serial number format to the identification section in the manual.
- If the label is damaged, check for a secondary label on the chassis.
- Keep the model number 917272950 handy when ordering parts like belts, steering parts, or electrical switches.
Why the “year” can be hard to state from the model number alone
On many Craftsman tractors, the model number identifies the configuration (chassis, deck family, steering assembly), while the serial number is what ties your tractor to a specific production run.
What you can use instead of the year (for parts matching)
| What to match | Best for | Example on this model |
|---|---|---|
| Model number (917272950) | Correct diagrams and assemblies | Mower deck, steering assembly |
| Part number / part ID | Exact replacement part | Riding lawn mower blade drive belt 532148763 |
| Serial number | Narrowing production date and revisions | ID label on tractor |
Why it matters
The correct production run helps avoid fit issues when replacing high-impact items like the blade drive belt, PTO switch, steering linkage, or deck hardware. Small mid-year changes can affect belt routing, brackets, and electrical connectors.

What engine does Craftsman riding mower use?
The Craftsman riding mower model 917272950 uses a 20 HP engine (as listed in the tractor’s documentation). For the most accurate engine details for your exact tractor, match the engine identification numbers shown in the 917272950 owner's manual.
How to identify the exact engine on your tractor
Even when horsepower is listed, the engine make and model are confirmed by the ID tag on the engine itself.
- Park on a level surface, set the parking brake, and let the engine cool completely
- Lift the hood and locate the engine ID label (often on the blower housing, valve cover, or near the starter)
- Record the model, type, and code (common on Briggs & Stratton engines)
- Compare those numbers to the engine information section in the 917272950 owner's manual
- Use the engine ID numbers when ordering tune-up parts (air filter, spark plug, fuel filter)
What we can confirm from the manual (model 917272950)
The manual for this Craftsman tractor calls out key engine-related specs you can use for maintenance and troubleshooting.
| Item | Specification (from manual) |
|---|---|

What model number is the Craftsman 42 riding mower?
For the Craftsman riding mower on this page, the model number is 917.272950 (often written without the dot as 917272950). We recommend confirming the exact model from the ID label and the 917272950 owner's manual so you match the correct parts and diagrams.
Where to find the model number on the mower
Look for the product identification label in common locations such as:
- Under the seat pan or seat bracket area
- On the frame rail near the engine
- Near the rear fender or battery compartment
- Under the hood area on the chassis
- On the mower deck shell (sometimes a separate deck tag)
Why your “42-inch” description may not match this model
This Craftsman 917272950 is documented as a garden tractor with a 46-inch mower deck in the manual. If you have a 42-inch deck, you may be looking at a different Craftsman model, or your tractor may have a different deck installed.
Quick check
| What you have | What to verify | What it affects |
|---|---|---|
| 42-inch deck | Deck tag and tractor model label | Deck belts, blades, mandrel parts |
| 46-inch deck | Manual and deck diagram match | Correct deck hardware and belt routing |
Parts matching tips (so you order the right item)
When ordering Craftsman tractor parts, we use the tractor model number first, then match the specific system (mower deck, steering, engine, electrical).
- Match the tractor model: 917272950
- Match the deck size shown in your diagrams (42 vs 46)
- Compare part descriptions to your assembly
- Use the illustrated parts list in the 917272950 owner's manual
- If you are troubleshooting PTO engagement, the switch 582107601 is a common electrical wear item on many tractors
Why it matters
Using the correct model number prevents wrong-fit parts, especially for deck components (belts, blades, mandrel housings) and electrical items (PTO switch, ignition harness).
