How much does it cost to replace a riding lawn mower engine?
For a Craftsman lawn tractor like model 917274033, a full engine replacement (parts plus labor) typically runs about $260 to $1,800 installed, depending on the engine type, shop labor rate, and any extra repairs needed during the swap. Confirm the correct engine specs and procedures in the 917274033 owner's manual.
What drives the total replacement cost
Engine replacement pricing varies because the “engine” cost is only part of the job. Common cost drivers include:
- Engine brand and horsepower (OEM-style vs aftermarket equivalent)
- Labor time (riding mower engine swaps commonly take several hours)
- Extra parts discovered during teardown (belts, pulleys, wiring, fuel lines)
- Deck and drive system condition (worn components can add time)
- Pickup/delivery and seasonal demand at local service shops
Typical cost breakdown (what you are paying for)
| Cost item | Typical range | Notes |
|---|---|---|
| Replacement engine | $200 to $1,400 | Biggest variable; depends on spec match |
| Labor | $60 to $400+ | Based on shop rate and hours |
| Misc. parts/fluids | $0 to $200 | Oil, filter, fuel line, clamps, hardware |
| Optional tune-up items | $0 to $250 | Battery, spark plug, air filter, etc. |
Before you replace the engine, check these quick items
Many “needs an engine” symptoms are caused by starting or fuel issues. We recommend checking:
- Battery and cable connections (clean and tight)
- Safety interlock switches (seat, brake, PTO)
- Fuel quality (old fuel can prevent starting)
- Air filter condition (restricted airflow can mimic engine failure)
- Starter/solenoid symptoms (clicking vs cranking)
If the engine clicks but will not crank, use riding lawn mower engine clicks but doesnt turn over video to narrow it down.
Why it matters
An engine replacement can approach the value of an older riding mower. Getting an accurate diagnosis first helps you avoid paying for a major repair when a battery, wiring issue, or safety switch is the real cause.

How to confirm the engine model on your tractor
We recommend matching the manual listing to the engine’s ID tag on the mower so you order the right tune-up and fuel parts.
- Park on a flat surface, set the parking brake, and let the engine cool.
- Lift the hood and look for the Briggs model-type-code label (often on the blower housing or valve cover area).
- Confirm the model number matches 407577-0284-E1.
- Record the full Briggs “model/type/code” for the most accurate parts matching.
- If the label is dirty, wipe it gently; do not scrape off the printing.
What the manual tells us about this engine setup
The manual’s engine breakdown for model 917274033 identifies the engine and several related components (fuel tank, oil drain tube/plug, throttle and choke controls).
| Item | What to look for | Why it helps |
|---|---|---|
| Engine model | Briggs 407577-0284-E1 | Confirms the correct engine family and spec |
| Fuel system | Rear fuel tank and fuel line routing | Helps when diagnosing fuel delivery issues |
| Oil drain | Easy oil drain plug/tube parts shown | Helps with oil change and leak checks |
Why it matters
Briggs engines can share the same horsepower range but use different carburetors, ignition parts, and filters. Verifying the exact engine model prevents wrong-part orders and speeds up troubleshooting.
