How to look up Craftsman model number?
For a Craftsman riding lawn tractor like model 917270682, we look up the model number by finding the model and serial tag on the tractor and then using that exact model number (and often the serial) to match the correct parts list and owner's manual. The tag is typically on the frame under the seat or on the underside of the seat; confirm the exact location in the 917270682 owner's manual.
Where to find the model and serial tag
Check these common locations first (clean off grass and dirt so the numbers are readable):
- On the frame directly under the seat
- On the underside of the seat pan
- Near the rear fender area around the seat mounting points
- On a sticker or metal plate with “Model” and “Serial” fields
What to write down (so parts match)
Record the information exactly as shown on the tag.
- Full model number (example format: 917.270682)
- Serial number
- Any product number or type number listed
- Engine model information (helpful for engine parts)
Quick match guide
| You have | Use it for | Why it helps |
|---|---|---|
| Model number (917270682) | Tractor and deck parts lookup | Ensures diagrams and parts lists match |
| Serial number | Production break matching | Avoids ordering the wrong revision |
| Engine model/type | Engine-specific parts | Engines can vary within the same tractor model |
Why it matters
Craftsman tractors often share similar frames and mower decks across multiple models. Using the exact model number and serial number prevents mismatches on common wear items like blades, belts, mandrel parts, and steering components.
Related parts you might match by model
If you are confirming deck-related parts for 917270682, a common example is the husqvarna lawn tractor mulching blade, 21-in 532134149. Always verify fit by model and deck configuration before ordering.

What engine does Craftsman riding mower use?
The Craftsman riding mower model 917270682 uses a 16.0 HP, electric-start engine (as specified in the 917270682 owner's manual). This model is an automatic lawn tractor with a 42-inch mower deck, so it is built for steady power and consistent cutting performance.
What we can confirm for model 917270682
From the model documentation, we can rely on these model-specific details:
- Engine output: 16.0 HP
- Starting system: electric start
- Mower deck size: 42 inches
- Tractor type: front-engine, automatic lawn tractor
- Brand: Craftsman
What “engine does it use?” usually means
Many owners are really asking for the engine manufacturer (for example, Briggs & Stratton, Kohler, Tecumseh) or the engine model number. On riding mowers, that information is typically found on:
- The engine ID label on the blower housing or valve cover area
- The emissions label (often near the muffler or shroud)
- The engine section of the 917270682 owner's manual
Quick ID checklist (before ordering engine parts)
Use these steps so you match the correct tune-up and fuel parts:
- Write down the engine model, type, and code from the engine label
- Confirm whether your tractor has a single-cylinder layout (common on 16 HP tractors)
- Check that the deck is the 42-inch configuration before buying blades or mandrel parts
- If you are servicing the cutting system, inspect the mandrel and blade mounting star
Related specs at a glance
| Item | What to look for | Why it matters |
|---|---|---|
| Horsepower | 16.0 HP | Helps match engine service parts and performance expectations |
| Start type | Electric start | Points to battery, starter, solenoid, and key switch checks |
| Deck size | 42-inch | Determines blade length, belt routing, and mandrel style |
Why it matters
The exact engine make and model controls which spark plug, air filter, fuel filter, and carburetor parts fit. Even within the same Craftsman tractor model family, engine variants can change what maintenance parts you need.

How much does it cost to replace a riding lawn mower engine?
For a Craftsman riding tractor like model 917270682, a complete engine replacement (parts plus labor) typically runs $600 to $2,500. The biggest cost drivers are the engine brand/horsepower, whether the replacement is a direct bolt-on match, and the labor time to swap and test it.
What affects the total price?
- Engine cost: New replacement engines commonly fall in the $400 to $1,800 range.
- Labor time: Most riding mower engine swaps take 4 to 8 hours depending on access, wiring, and pulley alignment.
- Extra parts and supplies: Oil, filter, fuel line, clamps, belts, and hardware often add $25 to $200.
- Electrical and safety checks: Seat switch, brake/clutch interlock, and wiring condition can add time.
- Fuel condition: Stale fuel can create “new engine” starting issues; our manual guidance is to use fuel within about 30 days of purchase. See the 917270682 owner's manual.
Quick cost breakdown (typical ranges)
| Cost item | Typical range | Notes |
|---|---|---|
| Replacement engine | $400 to $1,800 | Varies by spec and availability |
| Labor | $200 to $700 | Based on shop rate and hours |
| Fluids, filter, misc. parts | $25 to $200 | Oil, filter, clamps, hardware |
| Total installed | $600 to $2,500 | Most common real-world range |
Before you replace the engine, check these items
Many “needs an engine” symptoms are caused by starting, fuel, or safety interlock problems.
- Battery charge and cable connections
- Starter solenoid and starter motor operation
- Safety interlock switches (seat switch, brake/clutch switch, PTO switch)
- Fuel freshness and fuel delivery (stale fuel is a common culprit)
- Basic tune-up items (spark plug, air filter)
If the engine clicks but won’t turn over, use riding lawn mower engine clicks but doesnt turn over video to narrow it down before committing to an engine.
Why it matters
An engine is one of the highest-cost repairs on a riding mower. Confirming the real failure first helps you avoid replacing an engine when the actual fix is a battery, wiring issue, or safety switch adjustment.

How do I tell what year my Craftsman mower is?
For Craftsman lawn tractors like model 917270682, the year is identified from the product identification tag (model and serial number). Find the tag, record the serial number exactly, then decode the date code format used on that tag; our 917270682 owner's manual helps you confirm you are using the correct tractor model information.
Where to find the identification tag
On many Craftsman front-engine lawn tractors, the model and serial tag is commonly located:
- Under the seat or on the seat pan/bracket area
- On the rear fender pan near the seat
- On a frame rail near the engine compartment
- Near the footrest area on the frame
Clean the tag and copy the serial number character-for-character.
How to decode the build year from the serial number
Craftsman used multiple serial formats over time. Use these checks in order:
- Look for a 6-digit date code that reads MMDDYY; the last two digits are the year
- If the serial is longer, look for a 6-digit block that matches a real month and day (01-12 and 01-31)
- If the tag prints MFG DATE or DOM, use that printed date as the build date
Example date code
| Code on tag | Decodes as | Build year |
|---|---|---|
| 071294 | July 12, 1994 | 1994 |
Why it matters
The build year helps us match the correct parts and diagrams for your exact tractor configuration (mower deck, steering, wheels). That prevents ordering a look-alike part that does not fit.
Tips to avoid common mistakes
- Use the tractor serial tag, not the engine model number
- Record letters and numbers carefully; one wrong digit can change the year
- Use the model number exactly as shown for this tractor: 917270682
