How to look up Craftsman model number?
On the Craftsman riding lawn tractor model 917270662, you can look up the model number by finding the model and serial tag on the tractor frame under the seat (or on the underside of the seat) and matching that number to your parts list and diagrams in the 917270662 owner's manual.
Where to find the model and serial number tag
We see the model listed as 917.270662 in the documentation; the tag on your tractor typically shows the same model number format.
Check these common locations:
- On the frame under the seat (lift the seat up)
- On the underside of the seat pan
- Near the rear fender area under the seat mounting zone
- On a frame rail close to the battery tray (varies by build)
How to use the model number once you find it
After you confirm the model number, use it to pull the correct parts breakdown for your exact deck and drivetrain configuration.
- Match the full model number exactly (example: 917270662)
- Use the parts diagrams to identify the part name first, then confirm the part ID
- Cross-check the deck section if you are ordering cutting parts (blade, mandrel, belt)
Example: model-specific parts you can identify by diagram
| What you are fixing | What the diagram helps you confirm | Example part for this model |
|---|---|---|
| Poor cut quality or damaged blade | Blade style and mounting | Husqvarna lawn tractor mulching blade, 21-in 532134149 |
| Deck vibration or squeal | Mandrel and pulley stack | Husqvarna lawn tractor mandrel assembly 532130794 |
| Tractor will not move properly | Ground drive belt routing and length | Lawn tractor ground drive belt, 1/2 x 82-in 532140294 |
Why it matters
Craftsman tractors often share similar looks across multiple model numbers. Using the exact model number prevents ordering the wrong mower deck parts, belts, or steering components, and it keeps maintenance specs aligned with your tractor.

Is it worth replacing a lawn mower engine?
Replacing the engine on your Craftsman 917270662 lawn tractor is worth it when the tractor’s deck, transmission, steering, and safety systems are in good shape and the total engine swap cost stays well below the cost of a comparable replacement tractor. If the tractor also needs major deck or drive repairs, replacement usually makes more sense.
Quick decision checklist
- The mower deck is solid (no major rust-through) and cuts well after basic service (sharpen blades, clean underside).
- The tractor still drives normally (no slipping or loss of drive).
- Steering and brakes operate correctly.
- Safety interlock functions correctly (seat switch, clutch/brake start logic, attachment clutch behavior).
- You can complete an engine swap safely (fuel handling, wiring, throttle/choke linkage, belt routing).
Cost rule of thumb (simple and practical)
Use this guideline for the Craftsman 917270662:
| Scenario | What it usually means | Best choice |
|---|---|---|
| Engine is bad, everything else is strong | You are buying years of additional service life | Replace engine |
| Engine is bad and deck needs major work (mandrels, pulleys, belt) | Costs stack quickly | Consider replacing tractor |
| Engine is weak but starts and runs | A tune-up may restore performance | Service first |
Why deck and blade condition matters
A “new engine” does not fix poor cutting caused by deck issues. The manual calls out common cut-quality causes like worn or bent blades, an unlevel deck, and grass buildup under the housing. Keeping blades sharp and the deck clean protects your investment whether you replace the engine or not. See the 917270662 owner's manual for blade care, blade installation direction, and blade bolt torque guidance.
Parts that often get addressed with an engine decision
If your deck has vibration, uneven cut, or blades that will not rotate, these are common wear items to inspect:
- Blade and mounting hardware (bent blade, loose bolt)
- Mandrel and pulley wear (bearing noise, wobble)
- Deck belt condition and idler movement
If you are refreshing the deck at the same time, a common wear item is the husqvarna lawn tractor mandrel assembly 532130794.
Why it matters
An engine swap only pays off when the rest of the tractor is safe and mechanically sound. The manual emphasizes keeping safety devices working properly and avoiding adjustments or repairs with the engine running; that same safety-first approach should guide an engine replacement decision.

What engine does Craftsman riding mower use?
The Craftsman riding mower model 917270662 uses a 15.5 HP engine with electric start, as shown in the model’s documentation. For the exact engine make, model, and service details, we follow the identification steps in the 917270662 owner's manual.
How to identify the exact engine on model 917270662
Engine brands and model numbers are typically listed on the engine itself (not just on the tractor decals). Use these quick checks:
- Look for the engine ID label on the blower housing, valve cover, or near the starter
- Record the engine model, type, and code (or spec number)
- Match that information when ordering tune-up parts (spark plug, air filter, fuel filter)
- Use the tractor model number 917270662 when looking up chassis parts (deck, belts, steering)
- If the label is dirty, wipe it clean; avoid scraping off the printed code
What the manual confirms (and what it helps you find)
The documentation for this tractor calls out the key engine configuration and where to go for specs and maintenance intervals.
| Item | What we use for model 917270662 | Where to confirm details |
|---|---|---|
| Engine output | 15.5 HP | 917270662 owner's manual |
| Starting system | Electric start | 917270662 owner's manual |
| Mower deck size | 42-inch deck | 917270662 owner's manual |
| Exact engine make/model | Read from engine ID tag | Engine label + 917270662 owner's manual |
Why it matters
The engine make and model determine the correct air filter, spark plug, oil type, and many fuel-system parts. Using only “Craftsman 917270662” can be enough for tractor chassis parts, but engine service parts often require the engine’s ID code.

What year did Craftsman make the 917270662?
Craftsman model 917270662 is a 15.5 HP, electric-start, 42-inch automatic front-engine lawn tractor; the owner’s manual excerpt confirms the model number and specs but does not list a single “model year.” To pin down the exact build year, we use the tractor’s product identification label and cross-reference it with the information in the 917270662 owner’s manual.
How to find the build year on the tractor
Look for the product identification label (often under the seat, on the rear fender pan, or near the frame by the engine). On many Craftsman 917-series tractors, the label includes a date code or serial number that indicates when it was built.
- Park on a flat surface, set the parking brake, and remove the key
- Lift the seat and check the underside of the seat pan and frame rails
- Check the rear fender area near the left or right wheel
- Wipe the label clean so the full serial and any date code is readable
- Write down the model number (917270662) and the serial/date code exactly
What we can confirm from the manual (and what it means)
The manual identifies the tractor as model 917.270662 and describes it as 15.5 HP, electric start, 42-inch mower, and automatic. Those details help match the correct parts and diagrams, but they do not uniquely identify a single production year.
| Item | What it tells you | Where it helps |
|---|---|---|
| Model number (917270662) | Product family and configuration | Selecting correct parts and diagrams |
| Serial/date code | Actual build timing | Determining the year |
| Engine model (example shown in manual) | Engine family and spec | Engine parts and service references |
Why it matters
The build year affects small running changes such as wiring routing, deck linkage hardware, and steering components. Using the serial/date code prevents ordering the wrong belt, pulley, or steering part.
