How much does it cost to replace a riding lawn mower engine?
For a Craftsman riding mower like model 917254410, a full engine replacement (parts plus labor) typically runs $260 to $1,800 installed, with about 6 hours of labor on most riding lawn tractors. Your final price depends on engine type, mounting pattern, and whether related drive components need service.
What drives the total cost
- Engine choice: OEM-style replacement vs. aftermarket equivalent
- Labor time: shop rate and how seized or rusted fasteners are
- Extra parts: belts, pulleys, wiring, fuel line, and hardware often get replaced at the same time
- Fuel system condition: dirty tank or degraded fuel can add cleanup time
- Delivery and disposal: shipping for the engine and disposal of the old one
Typical cost breakdown (installed)
| Cost item | Typical range | Notes |
|---|---|---|
| Replacement engine | $200 to $1,400 | Biggest variable; depends on horsepower and crankshaft specs |
| Labor | $200 to $600 | Often 5 to 7 hours at local shop rates |
| Misc. parts and supplies | $20 to $200 | Belts, clamps, oil, filter, hardware |
Smart checks before you buy an engine
- Confirm the crankshaft diameter, length, and keyway match your current engine.
- Verify the bolt pattern and muffler/exhaust clearance.
- Inspect the ground drive belt and idlers; a worn belt can mimic “weak engine” symptoms.
- Check the ignition switch and wiring if the mower will not crank.
- Look for fuel contamination; a damaged tank can cause repeat problems.

Why it matters
An engine swap is one of the highest-cost repairs on a riding mower. Verifying crankshaft specs and addressing wear items (like belts and electrical starting parts) prevents fitment issues and helps the new engine deliver full power and reliable starting.

How to look up Craftsman model number?
For a Craftsman riding mower like model 917254410, we look up the correct model number by finding the model and serial tag on the tractor (most often under the seat or on the seat underside), then using that exact number to match parts and diagrams.
Where to find the model number on a Craftsman riding mower
Check these common locations first:
- On the frame under the seat (lift the seat and look for a sticker or metal tag)
- On the underside of the seat itself
- Near the rear fender or frame rail close to the seat mounting area
- On the mower deck shell (less common, but possible on some builds)
How we recommend you “look it up” for parts
Once you find the tag, use the model number exactly as printed (including all digits).
- Write down the model number and serial number
- Confirm the model number matches the format like 917.254410 or 917254410
- Use the model number to pull the correct parts list for your tractor
- Match parts by part name, part ID, and where it appears in the diagram
If you are working on the front axle or wheels, a common example part you might see listed for this model is the hub cap 532104757.
Quick checks to avoid ordering the wrong part
| What to check | What it should look like | Why it matters |
|---|---|---|
| Model number | 8 to 10 digits (often starts with 917) | Ensures the correct parts breakdown for your tractor |
| Serial number | Letters and numbers | Helps confirm production run differences |
| Product type | 44 inch, 6-speed mower garden tractor | Confirms you are in the right family of parts |
Why it matters
Craftsman tractors can look similar across years, but small differences in steering, deck drive, and fuel system parts can change by model number. Using the exact model number is the fastest way to get the right belt, pulley, ignition switch, or fuel tank the first time.

What brand engine does Craftsman use?
Craftsman riding mowers and lawn tractors (including model 917254410) are commonly equipped with engines from major small-engine makers such as Briggs & Stratton, Kohler, and sometimes Kawasaki. The exact engine brand depends on the specific Craftsman model and engine spec number on the engine itself.
How to identify the engine brand on model 917254410
We recommend checking the engine ID label directly on the engine shroud or valve cover area. That label tells you the engine manufacturer and the engine model/type code.
- Look for a sticker or stamped tag on the blower housing (top/front of engine)
- Record the engine brand (Briggs & Stratton, Kohler, Kawasaki)
- Write down the engine model and spec/type code
- Use that engine info when ordering tune-up parts (spark plug, air filter, fuel filter)
- If the label is missing, compare the engine’s physical features (air cleaner style, dipstick location) to common engine families
What Craftsman typically uses (quick comparison)
Engine suppliers vary by tractor series, deck size, and year. Here is what we most often see on Craftsman lawn tractors:
| Engine brand | Common on Craftsman tractors | Notes |
|---|---|---|
| Briggs & Stratton | Very common | Wide parts availability; many variants by spec code |
| Kohler | Common | Often found on higher-trim models and some series engines |
| Kawasaki | Less common | Frequently used on select premium models |
Why it matters
The engine brand and spec code determine the correct maintenance and repair parts. For example, a fuel system issue might point you toward replacing a cracked tank or contaminated fuel, but the correct filters and carburetor parts still depend on the engine’s exact identification.
If you are troubleshooting fuel delivery on this tractor, the model-specific fuel tank 532151346 is one of the parts we stock for Craftsman 917254410.

What year is a Craftsman 917254410 riding mower?
Craftsman model 917254410 does not map to one single “model year” the way cars do; this series of front-engine riding mowers was sold across multiple production runs. The most reliable way to pin down the exact year is to match the tractor’s product/serial information to the correct parts breakdown for 917254410 and its engine family.
How to identify the exact year on a 917254410
Use these checks on your Craftsman 44-inch 6-speed mower garden tractor:
- Look for the model and serial tag under the seat, on the frame rail, or near the rear fender pan.
- Write down the serial number exactly as shown (letters and numbers).
- Note the engine brand and model (often on the valve cover or blower housing).
- Compare your tractor’s configuration to the parts used on your unit (for example, ignition and fuel system parts).
- If the tractor has been repaired before, verify that major assemblies (engine, transaxle, deck) match the current build.
Parts clues that help confirm the correct production run
When the model year is unclear, confirming a few key parts helps ensure you are looking at the right configuration for Craftsman 917254410.
| What you check | What it tells us | Example part on this model page |
|---|---|---|
| Ignition switch style and connector | Helps match wiring and safety interlock setup | Lawn tractor ignition switch 532365402 |
| Fuel tank shape and outlet location | Helps match fuel line routing and mounting | Fuel tank 532151346 |
| Drive belt routing and length | Helps match deck/drive layout used in that run | Ground drive belt 583639501 |
Why it matters
Getting the year and production run right prevents ordering the wrong Craftsman riding mower parts (belts, ignition components, and fuel system pieces are common mismatch points). It also helps you troubleshoot correctly when symptoms point to a specific configuration.
Quick tip before you order parts
- Confirm the model number is exactly 917254410 on the tractor tag.
- Match at least one “hard ID” part (ignition switch or fuel tank) to your machine.
- If your tractor will not crank, start with the ignition and safety circuit checks, then verify the correct switch.
