Is it worth repairing a lawn mower engine?
Repairing the engine on your Craftsman lawn tractor model 917276702 is worth it when the problem is a basic maintenance or bolt-on fix (fuel, spark, starting, belts) and the tractor is otherwise solid. If the repair cost approaches about half the price of a comparable replacement tractor, replacement usually makes more sense.
Quick decision checklist
- Start with maintenance items first (fuel, spark plug, air filter, oil level and condition).
- If the engine cranks slowly or only clicks, test the battery connections and starting circuit.
- If it cranks but will not start, focus on fuel quality and ignition.
- If the tractor has good compression but runs poorly, a carburetor clean or tune-up is often worthwhile.
- If the crankshaft is bent or the engine has internal damage (knocking, seized), replacement is typically the better value.
Typical repair cost guide (what we see most often)
| Repair type | What it usually involves | Typical DIY cost range |
|---|---|---|
| Minor | Tune-up parts, fuel refresh, cleaning | $20 to $100 |
| Medium | Carburetor service, starter/solenoid, belts | $100 to $300 |
| Major | Internal engine work, major mechanical damage | $300+ |
Model-specific tips that affect “worth it”
Your 917276702 manual emphasizes that many common wear items are normal maintenance (blades, spark plugs, air cleaners, belts, oil filters) and that stale/contaminated fuel can drive fuel-system repairs; using fuel within about 30 days helps prevent repeat problems. Use the 917276702 owner's manual to follow the correct maintenance schedule and operating practices.
Why it matters
A riding mower engine problem is often caused by simple issues (stale fuel, dirty air filter, weak battery) that are inexpensive to correct. Fixing those first prevents unnecessary parts replacement and gets you back to reliable starting and full-speed mowing performance.

How much does it cost to replace a riding lawn mower engine?
Replacing the engine on a Craftsman riding tractor like model 917276702 typically costs $260 to $1,800 installed, depending on the engine type, labor rates, and whether related items (battery cables, belts, pulleys) also need service. Engine replacement labor commonly runs about 6 hours.
What drives the total cost?
- Engine price: new replacement engines vary widely by horsepower, shaft size, and mounting pattern
- Labor time and shop rate: most of the bill is removal, transfer of parts, and setup
- Extra parts discovered during the swap: worn belts, idlers, wiring, or fuel system issues
- Electrical starting issues: a “no crank” problem can look like an engine failure
- Deck and drive condition: if the tractor has other major wear, repair value changes
Quick cost breakdown (typical ranges)
| Cost item | Typical range | Notes |
|---|---|---|
| Engine (part only) | $200 to $1,400 | Varies by spec and brand compatibility |
| Labor | $300 to $900 | Often about 6 hours total |
| Misc. parts and shop supplies | $20 to $200 | Fuel line, clamps, hardware, oil, filter |
Before you replace the engine, rule out common “won’t start” causes
The troubleshooting steps in the 917276702 owner’s manual point first to basics like battery, wiring, fuse, ignition switch, and solenoid or starter. Check these items before committing to an engine swap:
- Battery charge and cable connections (clean and tight)
- Fuse condition
- Wiring harness connections at the starter and frame ground
- Ignition switch operation
- Starter solenoid function (a common failure point)
- PTO clutch disengaged and brake pedal fully depressed (safety interlocks)
If you suspect a solenoid issue, the lawn tractor starter solenoid 582042802 is a model-matched replacement part.
Why it matters
An engine replacement is one of the highest-cost repairs on a riding mower. Confirming the problem is not electrical (battery, solenoid, ignition switch) prevents unnecessary expense and gets your Craftsman tractor back to mowing faster.

What engine does Craftsman riding mower use?
Craftsman riding mowers use engines from common small-engine makers (most often Briggs & Stratton, Kohler, or similar), and the exact engine on Craftsman model 917276702 is identified by the engine’s model and spec numbers on the engine itself. Use the 917276702 owner's manual to locate the engine identification information and match service parts correctly.
How to identify the exact engine on model 917276702
Find the engine ID tag so you can match tune-up parts and service specs accurately:
- Look for an engine label on the blower housing, valve cover, or near the starter
- Record the engine brand and the model/type/code (or model/spec)
- Use those numbers when shopping for spark plugs, air filters, and fuel system parts
- If the label is dirty, wipe it clean and take a clear photo for reference
- Keep the tractor model number 917276702 with your engine numbers for future repairs
Quick starting-system checks (often mistaken for “engine problems”)
If the tractor clicks or cranks slowly, the issue is usually electrical, not internal engine damage:
| Symptom | Most likely area | What to check first |
|---|---|---|
| Clicks but won’t crank | Battery or starter circuit | Battery terminals, ground cable, fuse |
| Cranks but won’t start | Fuel or ignition | Fresh fuel, choke setting, spark plug wire |
| No click, no crank | Safety interlocks | Brake pedal switch, seat switch, PTO off |
If you confirm the battery and cables are good but it still only clicks, the lawn tractor starter solenoid 582042802 is a common no-crank component on this tractor platform.
Why it matters
The engine’s model and spec determine the correct maintenance items (oil type, spark plug, air filter) and the right adjustment procedures. Matching by engine ID prevents ordering the wrong parts even when the tractor model number is correct.
