How much does it cost to replace a riding lawn mower engine?
Replacing the engine on a Craftsman riding lawn tractor model 917287301 typically costs about $600 to $2,500 total (engine plus labor), with most installs taking 4 to 8 labor hours depending on wiring, throttle/choke linkages, and deck/belt setup. For model-specific procedures, use the 917287301 owner's manual.
What drives the total cost
- Engine type and horsepower (OEM-spec vs. compatible replacement)
- Labor time (shop rate and how much teardown is required)
- Extra parts discovered during removal (belts, pulleys, wiring)
- Fuel system cleanup if old fuel caused starting issues
- Battery/starting circuit condition (weak battery, corroded cables)
Typical cost breakdown
| Cost item | Typical range | Notes |
|---|---|---|
| Replacement engine | $400 to $1,800 | Biggest variable; match crankshaft size and mounting pattern |
| Labor | $200 to $900 | Commonly 4 to 8 hours at local shop rates |
| Misc. parts/fluids | $25 to $150 | Oil, filter, clamps, hardware, fuel line |
| Optional “while you’re in there” parts | $30 to $120 | Belts, idlers, battery cables |
Smart checks before you replace the engine
Many “needs an engine” symptoms are caused by serviceable issues. We recommend checking these first:
- Battery charge and cable connections (clean terminals)
- Starter/solenoid operation; a click with no crank often points to the starting circuit
- Fresh fuel and a clean fuel filter (stale fuel and water in fuel are common)
- Air filter condition and cooling fins/air screen cleanliness
- Spark plug condition and tight plug wire connection
If you’re chasing a no-crank issue, the lawn tractor starter solenoid 582042802 is a common repair part when the battery and wiring check out.
Why it matters
An engine swap is one of the highest-cost repairs on a riding mower. Confirming the problem first helps you avoid replacing a good engine when the real issue is the battery, solenoid, fuel, or ignition system.

What engine does Craftsman riding mower use?
The Craftsman riding mower model 917287301 uses a low-emission gasoline engine (as noted in the operator documentation). For the exact engine make, model, and specifications (such as displacement and tune-up parts), match the engine ID label on your tractor to the details in the 917287301 owner's manual.
How to identify the exact engine on your 917287301
Use these quick checks so you order the right maintenance and repair parts:
- Look for the engine ID label on the blower housing, valve cover, or near the starter
- Record the engine model, type, and code (or spec number)
- Compare that ID to the engine section in the 917287301 owner's manual
- If the tractor cranks slowly or only clicks, check battery cables and starter circuit connections first
- If the engine turns but will not start, confirm fresh fuel and a clean air filter before replacing parts
Common engine-related symptoms and likely causes
| Symptom | What it usually points to | What to check first |
|---|---|---|
| Clicks but will not crank | Weak battery, bad connections, solenoid issue | Battery charge, cable tightness, solenoid terminals |
| Cranks but will not start | Fuel, spark, air restriction | Fresh fuel, spark plug, air filter |
| Starts then dies when you release brake | Safety interlock circuit issue | Seat switch, brake switch, PTO switch position |
If you suspect a no-crank condition, the starter circuit is a common place to focus; the lawn tractor starter solenoid 582042802 is one of the key components in that circuit.
Why it matters
Craftsman tractors can share the same tractor model number while using different engine variants over production runs. Confirming the engine ID prevents ordering the wrong tune-up parts (spark plug, air filter, fuel filter) and speeds up troubleshooting.

Is it worth replacing a lawn mower engine?
Replacing the engine on your Craftsman 917287301 front-engine lawn tractor is worth it when the tractor chassis, mower deck, and drive system are still solid and the total engine swap cost stays well below the cost of a comparable new riding mower. If the tractor also needs major deck or transmission work, replacement usually makes more sense.
Quick decision checklist
- The mower deck is not rusted through and still cuts evenly after leveling
- The tractor still drives normally (no slipping, no loss of drive)
- You can do basic maintenance safely (fuel, belts, blades) and follow the 917287301 owner's manual
- The engine failure is confirmed (low compression, thrown rod, severe smoking) and not a simple fuel/ignition issue
- You plan to keep the tractor several more seasons
Cost and effort: what to compare
Use this simple comparison to decide:
| Option | Best when | Typical downside |
|---|---|---|
| Replace engine (complete) | Deck and drivetrain are in good shape | Higher up-front cost, more labor |
| Repair engine (limited) | Problem is starter, fuel delivery, ignition, or tune-up items | May not solve internal wear |
| Replace tractor | Multiple major systems are worn (engine + deck + drive) | Higher total spend, setup time |
Before you commit: rule out common “no-start” causes
Many “bad engine” symptoms are actually starting or safety circuit issues. Check these first:
- Battery condition and cable connections
- Starter engagement and solenoid operation (a click with no crank often points here)
- Fuel flow (replace the in-line fuel filter once each season)
- Spark plug condition (replace at the start of each mowing season or every 100 hours)
- Cooling fins and grass screen cleanliness (overheating can cause engine damage)
If you’re hearing clicking or the engine won’t crank, follow riding lawn mower engine clicks but doesnt turn over video before pricing an engine.
Why it matters
An engine swap can extend the life of a good Craftsman tractor, but it only pays off if the rest of the machine is safe and mechanically sound. The manual also stresses keeping hardware tight, maintaining safety devices, and never making adjustments with the engine running, which is especially important during major repairs.
