What model number is the Craftsman 42 riding mower?
For the Craftsman 42-inch riding mower shown on this page, the model number is 917274822 (often written as 917.274822 in the manual). Use that full model number when ordering parts, looking up diagrams, or matching the correct 42-inch mower deck components.
Where to find the model number on the tractor
We recommend confirming the number on the tractor itself, then matching it to the documentation.
- Check the model label under the seat, on the frame, or near the rear fender area
- Write down the full number exactly as shown (including any dots)
- Match it to the cover page of the 917274822 owner's manual
- Use the same model number when searching for blades, belts, and deck parts
- If the label is hard to read, clean it gently and use a flashlight to see stamped characters
Model number vs. deck size (quick reference)
A 42-inch deck is a deck size, not a model number. Many Craftsman tractors use a 42-inch deck, so the model number is what ensures correct fit.
| Item | What it tells you | Example for this tractor |
|---|---|---|
| Model number | Exact tractor configuration | 917274822 (or 917.274822) |
| Deck size | Cutting width only | 42-inch mower deck |
Why it matters when buying parts
Parts like mower blades, mandrel components, and deck hardware can vary by tractor model even when the deck size is the same. Using 917274822 helps us match the correct Craftsman parts list and diagrams.
If you are shopping for common 42-inch deck wear items for this model, examples include the lawn tractor 42-in deck high-lift blade 532138971 and the husqvarna lawn tractor mulching blade, 21-in 532134149.

How much does it cost to replace a riding lawn mower engine?
For a Craftsman lawn tractor like model 917274822, a complete engine replacement (parts plus labor) typically runs $260 to $1,800 installed, with about 6 hours of labor for a riding mower engine swap. Exact cost depends on engine type, shop rates, and any extra repairs found during removal.
What drives the total price
- Engine cost (new, rebuilt, or used) is the biggest variable.
- Labor rate varies by region and service center.
- Extra parts often add cost (belts, pulleys, wiring repairs, fuel line, battery).
- Diagnosis time may be billed if the failure is not obvious.
- Tune-up vs. replace: many “no start” issues are fuel, spark, or safety interlock related.
Before you replace the engine, confirm it is actually bad
We recommend using the troubleshooting steps in the 917274822 owner’s manual to rule out common causes that mimic engine failure.
Common checks that often solve “dead engine” complaints:
- Battery charge and cable connections
- Fuse condition
- Starter/solenoid operation
- Spark plug condition and gap
- Fuel quality (stale fuel or water in fuel)
- Air filter restriction and oil level
Typical cost breakdown (example ranges)
| Cost item | Typical range | Notes |
|---|---|---|
| Replacement engine | $200 to $1,400 | Varies by HP, shaft size, and availability |
| Labor (riding mower) | $300 to $900 | Often ~6 hours total |
| Misc. parts/fluids | $20 to $200 | Oil, filter, fuel filter, hardware, belts |
Why it matters
An engine replacement can exceed the value of an older tractor. If the tractor still cuts well and the transmission and deck are solid, replacing the engine can be a smart way to extend the life of your Craftsman 917274822.

What year did Craftsman make the 917274822?
Craftsman model 917274822 does not map to one single “model year”; it’s a Sears model number used across a production run, and the exact build date is identified on the tractor’s product ID label. We use the 917274822 owner's manual to match the correct decals, chassis, and electrical parts for your specific unit.
How to find the exact year on your tractor
Check the product identification label (often under the seat, on the frame rail, or near the rear fender pan). Record these items:
- Model number: 917274822
- Serial number
- Date code (if listed)
- Engine model and code (on the engine tag)
- Any product number or “MFG ID” shown on the label
What the manual confirms (and why it matters)
The documentation we have is clearly labeled TRACTOR MODEL NUMBER 917.274822 and includes model-specific diagrams and parts lists (for example, electrical, chassis, steering, and decals). That tells us the manual is the right reference for identifying assemblies, but the build year is still determined by the ID label and serial/date code on your tractor.
Quick parts clues that help confirm you are matching the right tractor
When you are cross-checking your tractor against parts diagrams, these model-specific items are commonly used as “sanity checks”:
- Molded ignition key (often listed as key, molded) such as molded ignition key 532140403
- Chassis and enclosure identifiers (hood, fender/footrest, dash lower)
- Steering linkage layout (drag link, sector gear, axle assembly)
- Decal set names and placements
Common production-era guidance (typical for 917-prefix Craftsman tractors)
Many Craftsman tractors with 917 model numbers were produced broadly from the late 1990s through the mid-2000s. Use this only as a general range; the ID label provides the exact year.
| What you have | What it tells us |
|---|---|
| Model number only (917274822) | Identifies the correct parts breakdown and manual |
| Serial number and date code | Identifies the exact build date/year |
| Engine code | Helps confirm the production timeframe |
Why it matters
The exact year affects parts fitment for items like wiring harnesses, safety interlock switches, deck components, and steering hardware. Using the ID label details prevents ordering the wrong blade, belt, or electrical part.
