Do Craftsman mowers use Briggs and Stratton engines?
Yes, many Craftsman mowers and lawn tractors use Briggs and Stratton engines, but it depends on the specific model and production year. For Craftsman model 917258890, the engine brand is determined by the engine model tag on the engine itself, not by the tractor model number.
How to tell what engine is on a Craftsman 917258890
Check the engine identification label (usually on the blower housing, valve cover, or near the starter). Record the engine brand and the model-type-code (Briggs) or the equivalent ID (other brands).
- Look for a Briggs and Stratton logo and a model number format like 12H802-xxxx-xx
- If you see Kohler, Kawasaki, or another brand, use that brand’s engine ID format
- Match parts by the engine model, not just the tractor model
- If the label is dirty, wipe it clean and use a flashlight to read stamped characters
- If the label is missing, the engine shroud or valve cover sometimes has a stamped ID
Why Craftsman models can have different engine brands
Craftsman tractors were commonly built by major OEMs and could be sold with different engine options over time. That means two Craftsman tractors can look similar but use different engines and tune-up parts.
| What you’re checking | Where to find it | What it’s used for |
|---|---|---|
| Tractor model (917258890) | Under seat, frame, or fender tag | Chassis, deck, steering, drive parts |
| Engine model tag | On the engine | Filters, spark plug, carb parts, starter parts |
Related parts that are not engine-specific
If you are troubleshooting operation issues (like the blades not engaging), the problem can be outside the engine. For example, a faulty PTO switch can prevent the electric clutch from engaging.
- Inspect wiring connectors for corrosion or looseness
- Check safety interlock switches (seat, brake, PTO)
- Verify the PTO switch clicks and feels consistent
- If the PTO switch is damaged or intermittent, replace it with the correct part

Why it matters
Using the correct engine brand and engine model number prevents wrong tune-up parts (air filter, fuel filter, spark plug) and speeds up repairs when the tractor cranks, clicks, or won’t start.

How much does it cost to replace a riding lawn mower engine?
For a Craftsman riding lawn tractor like model 917258890, a full engine replacement typically costs $260 to $1,800 installed, depending on the engine type, labor rates, and whether extra items (belts, pulleys, wiring) are needed during the swap.
What drives the total cost?
- Engine price (new vs. rebuilt, horsepower, shaft size, charging system)
- Labor time (most riding mower engine swaps run about 5 to 8 hours)
- Extra parts discovered during teardown (worn belts, mounts, fuel lines)
- Shop fees (pickup/delivery, disposal, diagnostics)
- Season and local rates (spring demand often increases scheduling and labor costs)
Quick cost breakdown (typical ranges)
| Cost item | Typical range | Notes |
|---|---|---|
| Engine (part only) | $200 to $1,400 | Varies by brand, output, and configuration |
| Labor | $200 to $800 | Based on hourly rate and time |
| Misc. parts and supplies | $20 to $200 | Fuel line, clamps, oil, filter, hardware |
| Total installed | $260 to $1,800 | Most common all-in range |
Before you replace the engine
We recommend ruling out common “no start” causes first, because they are often cheaper than an engine:
- Weak battery or bad battery cables
- Faulty starter solenoid or starter
- Safety interlock issue (brake, seat, PTO)
- Fuel delivery problem (stale gas, clogged line)
- Ignition issue (spark plug, coil)
A fast first check is whether the engine clicks, spins but will not start, or does nothing. The steps in riding lawn mower engine clicks but doesnt turn over video help narrow that down.
Why it matters
An engine replacement can cost close to the value of an older tractor. Confirming the failure first helps you avoid spending hundreds on an engine when the real fix is a switch, battery, or fuel issue.

How do I find the model number on my 917258890?
Your Craftsman riding mower model number is printed on a product ID label (model and serial tag) attached to the tractor frame. On model 917258890, check the common label locations below, then match the full number exactly when ordering parts.
Where to look on a Craftsman front-engine lawn tractor
Check these spots in order (labels are usually a sticker or metal tag):
- Under the seat on the seat pan or fender deck
- On the rear fender near the seat (left or right side)
- On the frame rail near the engine compartment
- Under the hood near the dash tower or steering column area
- Near the transaxle on the rear frame
What the label should show
Look for these fields on the tag so you capture the right information:
- Model number (for this tractor, it should read 917258890)
- Serial number (helps identify production run)
- Sometimes an engine model/type/code (engine parts use this, not the tractor model)
Quick check: tractor model vs. engine model
Use the tractor model number for chassis and deck parts; use the engine numbers for engine-specific parts.
| You need parts for | Use this number | Example on your unit |
|---|---|---|
| Mower deck, belts, steering, switches, wheels | Tractor model number | 917258890 |
| Carburetor, starter, ignition coil, engine gaskets | Engine model/type/code | Listed on engine shroud |
Why it matters
A single digit difference can change the correct diagrams and parts list. Using the exact model number helps ensure the right fit for items like the lawn tractor ignition switch 532140301 or the lawn tractor ground drive belt, 1/2 x 84-1/2-in 532140218.
