Does Craftsman use Briggs and Stratton engines?
Yes. Craftsman used Briggs & Stratton engines on many lawn tractors, and the Craftsman lawn tractor model 917271822 specifically lists a Briggs model 42E707 (type 2631-E3) engine in the engine breakdown in the owner's manual.
How to confirm what engine is on your 917271822
We recommend matching the engine information in two places so you order the right tune-up and engine parts.
- Check the engine ID label on the engine shroud or valve cover (model, type, code)
- Compare it to the engine listing in the owner's manual
- Use the full engine model and type when looking up engine-specific parts (carburetor kit, starter, gasket set)
- If the tractor has had an engine swap, trust the engine label over the tractor model number
What “Briggs model and type” means (quick reference)
| What you see | What it’s used for | Example for this tractor |
|---|---|---|
| Engine model | Identifies the engine family | 42E707 |
| Type number | Identifies the exact build configuration | 2631-E3 |
| Code | Identifies production date/version | Found on the engine label |
Why it matters
Briggs & Stratton engines can share the same model number but use different carburetors, starters, ignition parts, or gaskets by type number. Using 42E707-2631-E3 helps prevent ordering the wrong engine parts and speeds up troubleshooting.
Related parts you might replace on the tractor
Even when the engine is the main focus, these tractor parts commonly get serviced during mowing season:
- Blade and deck hardware (for cut quality)
- Ground drive belt (for traction and speed)
- Starter solenoid (for no-crank or click symptoms)
If you’re refreshing the cutting system, the husqvarna lawn tractor mulching blade, 21-in 532134149 is one of the listed replacement blades for this model.

What year is my Craftsman mower serial number lookup?
On a Craftsman lawn tractor like model 917271822, the model number does not tell you the build year by itself; you typically determine the year from the product identification label (serial number/date code) on the tractor. Use the date-code format shown in your 917271822 owner's manual and match it to the label on your machine.
Where to find the serial number (ID label)
We typically see the ID label in one of these spots on front-engine Craftsman tractors:
- Under the seat pan or on the seat support
- On the rear fender pan near the seat
- On the frame rail near the engine
- Near the transaxle area on the frame
How to decode the year from the serial number
Craftsman riding mower serial/date codes vary by production run, so the most reliable method is to read the exact format printed on your ID label and compare it to the identification information in the 917271822 owner's manual.
Common date-code patterns you may see include:
- MMDDYY (month, day, year)
- YYMMDD (year, month, day)
- A longer serial number where only a portion represents the date
Quick examples (format dependent)
| If your label uses this format | Example code | Interprets as |
|---|---|---|
| MMDDYY | 072811 | July 28, 2011 |
| YYMMDD | 110728 | July 28, 2011 |
Why it matters
Knowing the correct year helps you match the right maintenance parts and deck components (for example, blades, belts, and mandrel parts) and prevents ordering the wrong revision.
Parts that often depend on the exact build configuration
- Mower deck blade style and mounting
- Ground drive belt length
- Mandrel (spindle) shaft and housing style
- Electrical parts such as the starter solenoid and ignition key
If you are refreshing the cutting system on this model, the manual parts list for 917271822 shows a mulching blade and mandrel components that match common 42-inch deck setups, such as the husqvarna lawn tractor mulching blade, 21-in 532134149 and the vented mandrel shaft assembly 532137646.

How much does it cost to replace a riding lawn mower engine?
Replacing the engine on a Craftsman lawn tractor model 917271822 typically costs about $600 to $2,500 total (engine plus labor). Most of the cost is the engine itself; labor is commonly 4 to 8 hours depending on shop rates and whether pulleys, belts, or wiring need attention. See the 917271822 owner's manual for maintenance and safety steps that help prevent engine damage.
What makes the price go up or down
- Engine type and horsepower (single-cylinder vs V-twin, OEM-style vs aftermarket equivalent)
- Labor rate in your area and minimum shop charges
- Extra parts needed during the swap (belts, pulleys, hardware, battery cables)
- Fuel system cleanup if old or stale fuel caused problems (the manual notes fuel is best used within about 30 days)
- Deck and drive condition (worn belts or seized mandrels can add time)
Typical cost breakdown
| Cost item | Typical range | Notes |
|---|---|---|
| Replacement engine | $400 to $2,000 | Biggest variable; depends on spec and availability |
| Labor | $300 to $900 | Often 4 to 8 hours |
| Misc. parts and supplies | $25 to $200 | Belts, hardware, oil, filter, fuel line |
Parts that commonly get inspected during an engine replacement
Even if you are replacing the engine, we recommend checking these wear items so you do not reinstall a problem that causes poor performance or loss of drive:
- Ground drive belt such as lawn tractor ground drive belt, 1/2 x 82-in 532140294
- Starter circuit components such as solenoid 532146154
- Key and switch wear such as molded ignition key 532140403
- Blade drive components (mandrels, idlers, springs) if the deck was noisy or vibrating
Why it matters
A correct engine replacement is not just bolting in a motor. Proper belt routing, safe interlock operation, and correct throttle and brake behavior help prevent no-start issues and unsafe operation after the repair.
