How to find Craftsman model number?
On a Craftsman riding mower like model 917272074, we typically find the model number on the tractor frame under the seat (or on the underside of the seat itself). Once you have that number, you can match the correct diagrams, parts, and maintenance specs in the owner's manual.
Where to look on your Craftsman riding mower
Check these common spots first:
- On the frame directly under the seat (lift the seat up)
- On the underside of the seat pan
- Near the rear fender area close to the seat mounting points
- On a sticker or metal tag with both model and serial information
What the model number looks like
For this Craftsman lawn tractor, the model number format is a 9-digit number.
| What you see | What it means | Example |
|---|---|---|
| Model No. | Identifies the exact tractor configuration | 917272074 |
| Serial No. | Identifies your specific unit | Varies |
Tips to make sure you copy it correctly
A single wrong digit can pull up the wrong parts list, so we recommend:
- Wipe dirt and grass off the tag before reading it
- Write the number down and double-check each digit
- Take a clear photo of the tag for reference
- Use the model number (not the engine brand) when looking up tractor parts
Why it matters
The model number ties your mower to the correct parts diagrams and specifications (for example, this tractor is a 17 HP, 42-inch deck configuration). Using the right model number helps you choose compatible items like a blade, tire, or ignition key without guesswork.

What year is Craftsman Model 917272074?
Craftsman model 917272074 is identified by its model number in the tractor’s documentation; the owner’s manual for this exact model covers the 17 HP, 42-inch deck tractor configuration. For the most accurate “year” identification, we use the product ID/date code on the tractor (not the model number alone) and confirm it against the owner's manual.
How to find the build date on your tractor
Look for a product label (often under the seat, on the frame rail, or near the engine area). Many Craftsman riding mowers use a date code on the label that can be read as MMDDYY.
- Find the product label and locate the date code (if present)
- Read the code as month, day, year (example: 072811 = July 28, 2011)
- Record the full model number 917272074 and any serial/date code
- Compare the tractor configuration to the manual (engine HP, deck size, transmission type)
- Use the date code as the “year” reference for your specific unit
What we can confirm for model 917272074 from the manual
The documentation for Craftsman 917272074 describes this configuration:
| Spec item | What the manual shows for 917272074 |
|---|---|
| Tractor type | Front-engine lawn tractor |
| Engine | 17 HP (Kohler CV490) |
| Mower deck | 42-inch |
| Starting | Electric start |
| Drive | 6-speed transaxle |
Why the “year” is not the same as the model number
The model number identifies the tractor’s design and parts breakdown; the date code/serial information identifies when your specific tractor was built. That matters when you are matching maintenance parts (like blades, belts, or electrical components) to what is actually installed.
Parts that commonly get replaced on this model
If you are confirming the tractor’s age for maintenance planning, these are common wear items:
- Mower blade (deck cutting performance)
- Mandrel components (blade spindle area)
- Ignition key and starting circuit parts
For example, this model’s parts list includes the husqvarna lawn tractor mulching blade, 21-in 532134149 and the solenoid with brass plunger 532146154.

Is it worth replacing a lawn mower engine?
Yes; replacing the engine on your Craftsman lawn tractor model 917272074 is worth it when the tractor’s deck, steering, and transaxle are in good shape and the total engine job stays under about half the value of a comparable working tractor. Use the owner's manual to confirm the engine is the real failure.
Quick decision checklist
Replace the engine when most of these are true:
- The mower deck and chassis are solid (no cracks or severe rust-through)
- The transaxle drives smoothly (no slipping, grinding, or loss of drive)
- Steering and brakes operate normally
- Wiring and safety interlock system work correctly
- You can keep parts plus labor within your budget
Replace the tractor instead when most of these are true:
- The transaxle is failing (often a high-cost repair)
- The deck has major damage or repeated mandrel failures
- Multiple major systems need work at the same time (engine plus transaxle plus deck)
Cost and condition guide
| What to check | What “good” looks like | Why it matters |
|---|---|---|
| Transaxle | Strong pull, no slipping | Biggest cost risk after an engine |
| Deck/mandrels | No wobble, no chronic vibration | Protects belts, blades, and cut quality |
| Starting system | Cranks strongly | “Bad engine” symptoms can be electrical |
Confirm it is really an engine problem first
The 917272074 manual troubleshooting and maintenance sections point to common power-loss and running issues caused by basic service items.
- Check oil level and oil condition
- Clean the air intake and engine cooling fins; blocked cooling causes overheating damage
- Replace seasonal tune-up items (spark plug, fuel filter)
- Remove grass and debris buildup under the mower housing
- If it only clicks or will not crank, test the starting circuit
If the tractor clicks but will not crank, a common repair is replacing the starter solenoid; see solenoid with brass plunger 532146154.
Why it matters
An engine swap only pays off when it fixes the main problem. Verifying cooling airflow, fuel delivery, and the starting and safety circuits prevents spending engine-level money on a tractor that only needs routine maintenance or a bolt-on part.
