How much does it cost to replace a riding lawn mower engine?
For the Craftsman riding lawn tractor model 917287320, a typical engine replacement (parts plus labor) runs about $260 to $1,800 installed, with around 6 hours of labor in many shops. Total cost depends most on the engine type, whether wiring and pulleys transfer over cleanly, and any extra repairs found during removal.
What drives the price up or down
- Engine type and horsepower (OEM-style replacements cost more than basic equivalents)
- Labor rate (shop rates vary widely by region)
- Extra parts needed during the swap (belts, wiring, hardware, fuel line)
- Deck and drive condition (a worn belt or idler can add time)
- Electrical starting issues found during diagnosis (battery cables, solenoid, switch)
Common add-on repairs to budget for
Engine replacement often overlaps with “no-start” or “loss of power” symptoms. Our manual’s troubleshooting and maintenance sections are the best place to confirm what else needs attention; see the 917287320 owner's manual.
- Replace a weak starting component such as the lawn tractor starter solenoid 582042802
- Replace a worn deck or drive belt such as the lawn tractor ground drive or blade drive belt, 1/2 x 92-2/5-in 592855201
- Clean engine cooling fins and air intake areas to prevent overheating damage
- Replace the in-line fuel filter once each season (common cause of power loss)
- Check wiring connections and battery terminals if cranking is inconsistent
Quick cost snapshot
| Item | Typical range | Notes |
|---|---|---|
| Engine (part) | $200 to $1,500+ | Biggest variable; depends on spec and availability |
| Labor | $200 to $700+ | Often based on ~6 hours for riding mowers |
| Misc. parts/fluids | $20 to $200 | Belts, hardware, fuel line, oil, filter |
Why it matters
A new engine is one of the highest-cost repairs on a riding mower. Before committing, we recommend confirming the root cause (fuel, spark, cooling, or starting circuit) so you do not replace an engine when a solenoid, belt, or maintenance item is the real problem.

Is it worth replacing a lawn mower engine?
Yes; replacing the engine on your Craftsman 917287320 front-engine lawn tractor is worth it when the deck, steering, and drive system are in good shape and the total repair cost stays well below the price of a comparable replacement tractor. It is not worth it when multiple major systems are worn out.
Quick decision checklist
- Replace the engine if the deck is structurally solid (no rust-through or cracks).
- Replace the engine if it still drives strongly with no slipping or loss of drive.
- Replace the engine if the problem is clearly engine-related (low compression, heavy smoke, internal noise).
- Skip the engine swap if the deck has repeated spindle or mandrel problems.
- Skip the engine swap if the drive system also needs major work (belt, pulleys, transaxle).
Cost and condition guide
| Factor | Engine replacement makes sense | Replacement tractor makes sense |
|---|---|---|
| Overall condition | Frame, deck, controls are solid | Multiple systems are worn/damaged |
| Repair scope | Mostly engine-related | Engine plus deck/drive/steering issues |
| Budget | Repair is clearly cheaper | Repair total nears about 50% of replacement |
What to inspect before you decide
- Deck drive and cut quality: A worn belt or idler can feel like “low power”; check belt condition and routing.
- Mandrel area: Grass buildup around mandrels can hurt cut performance; inspect the lawn tractor mandrel housing 587819701 if you see wobble, noise, or chronic belt issues.
- Cooling and maintenance: Keep the grass screen and cooling fins clean to prevent overheating; follow the service guidance in the 917287320 owner’s manual.
Why it matters
An engine swap restores power and reliability, but mowing performance still depends on deck condition, blade sharpness, belt tension, and cooling airflow. Checking those items first prevents spending engine money on a tractor that still will not mow well.

What are some common problems with Craftsman riding lawn mowers?
Common problems on the Craftsman 917287320 riding lawn mower include no-crank or click-no-start issues, mower blades that will not rotate, poor grass discharge, and battery charging problems. Our 917287320 owner's manual troubleshooting chart also points to belt, idler pulley, and mandrel issues as frequent causes.
Most common symptoms and what usually causes them
- Engine clicks but will not turn over: weak battery, bad cable connections, starter solenoid, or safety interlock issue
- Engine spins but will not start: fuel, spark, or air delivery problems (often after storage)
- Mower blades will not rotate: worn or off-track mower drive belt, frozen idler pulley, or frozen blade mandrel
- Poor cut or poor discharge: deck not level, wet grass, low tire pressure, dull/bent blades, or debris buildup under the deck
- Battery will not charge: bad battery cell, poor connections, regulator (if equipped), or alternator
Quick checks we recommend before buying parts
- Park on level ground; set the parking brake, shut off the engine, and remove the key.
- Look for packed grass and debris under the mower deck and around the mandrels; clear buildup.
- Inspect belts for glazing, cracking, or slack; confirm the belt is routed on the engine pulley.
- Spin deck pulleys by hand (engine off, key removed); any pulley that feels rough or stuck needs attention.
- Check battery terminals for corrosion and tightness; confirm the ground connection is clean and secure.
Parts that commonly solve these problems on model 917287320
| Symptom | Common fix area | Example part for this model |
|---|---|---|
| Blades will not rotate | Deck drive system | Lawn tractor ground drive or blade drive belt, 1/2 x 92-2/5-in 592855201 |
| Blades will not rotate, noisy deck | Mandrel area | Lawn tractor mandrel housing 587819701 |
| Clicks but no crank | Starting circuit | Lawn tractor starter solenoid 582042802 |
| PTO will not engage blades | PTO control | Switch.pto 582107601 |
Why it matters
Catching belt, idler, and mandrel problems early helps prevent overheated pulleys, damaged spindles, and uneven cutting. Keeping the deck clean and the tractor maintained also improves safety and reduces downtime.

What engine does Craftsman riding mower use?
The Craftsman riding lawn tractor model 917287320 uses a low-emission gasoline engine (the operator’s manual notes it operates differently than older engines). For the exact engine make, model, and horsepower rating used on your tractor, we recommend checking the engine identification label and the 917287320 owner's manual.
How to identify the exact engine on your 917287320
Use these quick checks to match the correct engine parts and tune-up specs:
- Look for the engine model/type/code label on the engine shroud, valve cover, or blower housing
- Record the engine brand (commonly Briggs & Stratton, Kohler, or similar on tractors of this type)
- Note the horsepower or displacement listed on the label
- Match the label info to the specifications and maintenance sections in the manual
- If the label is dirty or faded, clean it gently and take a clear photo before ordering parts
What we can confirm from the manual (and what it means)
The manual for this tractor family calls out a low-emission engine and emphasizes reading operating instructions before starting.
Why that matters
Low-emission engines often have different starting and choke behavior than older designs, so using the correct throttle and choke procedure helps prevent hard starting, plug fouling, and poor mowing performance.
Quick operating tips tied to engine performance
These are common best practices for Craftsman tractors like model 917287320:
| Situation | Recommended control setting | Result |
|---|---|---|
| Mowing | Throttle at full speed (fast) | Best cut quality and engine efficiency |
| Cold start | Use choke, then ease it off as it warms | Faster starts, less stalling |
| Stopping | Turn key to STOP (do not use choke to stop) | Helps prevent battery drain |
Parts that commonly relate to “what engine do I have?”
Once you confirm the engine ID, these tractor systems are often involved in starting and drive complaints:
- Battery cables and connections (clean, tight terminals)
- Starter circuit components such as the lawn tractor starter solenoid 582042802
- Ignition switch and safety interlock switches
- Fuel quality (fresh fuel, clean filter)
- Air filter and spark plug condition
