How much does it cost to replace a riding lawn mower engine?
For a Craftsman lawn tractor model 917273142, replacing the engine typically costs $260 to $1,800 installed, depending on the engine type, labor rates, and whether related items (belts, wiring, pulleys) also need service. Most riding mower engine swaps take around 6 labor hours.
What drives the total cost
- Engine price (new vs. rebuilt, horsepower, shaft size, charging system)
- Labor time (engine removal, transfer of pulleys, wiring, throttle/choke linkages)
- Extra parts often replaced at the same time (belts, key, hardware)
- Condition issues discovered during the job (damaged wiring, worn pulleys)
- Shop rates in your area
Typical cost breakdown
| Cost item | Typical range | Notes |
|---|---|---|
| Engine (part only) | $200 to $1,400 | Biggest variable; must match shaft and mounting pattern |
| Labor | $200 to $700 | Often 5 to 7 hours for a riding mower |
| “While you’re in there” parts | $20 to $200 | Belts, key, fasteners, tune-up items |
| Total installed | $260 to $1,800 | Common real-world range |
Smart checks before you buy an engine
We recommend confirming the engine is truly the problem before replacing it, because many “no start” or “no crank” complaints are caused by fuel, ignition, or safety circuits.
- Verify the engine turns freely by hand (with spark plug removed)
- Check for fresh fuel and a clean fuel path (water in fuel is a common issue)
- Inspect wiring connections and safety interlocks
- Confirm spark plug wire is tight and the plug is serviceable
- Check for clogged cooling fins or a clogged muffler
For model-specific troubleshooting steps and safety guidance, use the 917273142 owner’s manual.
Why it matters
An engine replacement is one of the highest-cost repairs on a riding mower. A quick diagnosis can prevent spending hundreds on an engine when the real fix is a belt, wiring repair, or fuel system service.
