How much does it cost to replace a riding mower engine?
Replacing the engine on a Craftsman riding mower like model 917288522 typically costs $800 to $2,500 total (engine plus labor), depending on horsepower, crankshaft type, and whether you do the swap yourself or pay a shop.
Typical cost breakdown
- Engine (new): $500 to $1,800
- Labor (shop install): $300 to $900
- Pickup/delivery (if needed): $50 to $200
- Extra parts and supplies: $25 to $200 (oil, filter, fuel line, clamps, hardware)
| Scenario | What you pay for | Typical total |
|---|---|---|
| DIY engine swap | Engine + supplies | $550 to $2,000 |
| Shop replacement | Engine + labor + supplies | $800 to $2,500 |
| Repair instead of replace | Tune-up or starting system fix | $100 to $600 |
What changes the price the most
- Engine match details: crankshaft diameter/length, mounting pattern, and PTO setup (critical for deck engagement)
- Condition of the tractor: worn belts, pulleys, wiring, or fuel system can add time and parts
- Why it “needs an engine”: many no-start complaints are battery, wiring, or solenoid related
If your tractor only clicks or won’t crank, the manual troubleshooting chart points first to the battery, terminals, wiring, and solenoid. Checking those items can avoid an unnecessary engine replacement. See the 917288522 owner’s manual.
Before you buy an engine: quick checks we recommend
- Load-test the battery; clean and tighten battery terminals
- Inspect wiring at the starter and frame ground for corrosion or looseness
- Test the starter solenoid; replace if it’s not sending power to the starter
- Confirm the engine is not seized (remove spark plug and try to rotate by hand)
- Verify the deck and drive systems spin freely (a locked pulley or mandrel can overload the engine)
Parts that often get replaced during “engine” jobs
These are common add-ons when a tractor has starting or drive complaints:
- Lawn tractor starter solenoid 582042802
- Belts and pulleys (for example, a worn blade drive belt or idler pulley)
Why it matters
An engine swap is one of the highest-cost repairs on a riding mower. Spending 15 to 30 minutes diagnosing the starting and safety circuits first often turns a “needs an engine” situation into a much smaller repair.

Is it worth replacing a lawn mower engine?
Yes, it’s worth replacing the engine on your Craftsman 917288522 when the tractor is otherwise in solid shape (deck, transmission, steering) and the total repair cost stays well below the price of a comparable replacement tractor. If multiple major systems are worn out, putting that money toward a newer mower is the better value.
Quick decision checklist
- Replace the engine if the deck cuts well, the transmission drives smoothly, and the frame is sound.
- Replace the tractor if you also have loss of drive, major deck damage, or repeated electrical problems.
- Price it out first: engine cost + labor + tune-up parts + any “while you’re in there” repairs.
- Consider downtime: an engine swap can take days if extra parts are needed.
- Match the engine exactly: shaft size, crank length, charging output, and throttle/choke setup.
What to inspect on model 917288522 before spending money
Use the troubleshooting and service steps in the 917288522 owner’s manual to evaluate these common deal-breakers:
| Area to check | What you’re looking for | What it usually means |
|---|---|---|
| Transmission and drive | Slipping, no movement, or inconsistent speed | A second major repair that can outweigh an engine swap |
| Mower deck and spindles | Excess vibration, noisy mandrels, poor cut | Deck rebuild costs add up quickly |
| Starting system | Clicking/no crank, intermittent crank | Often battery, wiring, or solenoid, not the engine |
| Safety interlocks | Engine dies when releasing brake or engaging blades | Switch or wiring issues can mimic engine failure |
If the tractor only “clicks but won’t start,” the manual points to battery condition, corroded terminals, wiring, or a bad solenoid or starter. In that case, an engine replacement is usually unnecessary.
Parts that commonly get replaced during deck or drive repairs
If your “engine problem” is actually a blade-drive issue (blades won’t rotate, poor cut, belt smoke), these parts are often involved:
- Husqvarna lawn tractor blade drive belt 584453101 (worn or stretched belt)
- Lawn tractor mandrel housing 587819701 (noisy or loose spindle/mandrel)
- Mandrel pulley 532195945 (worn pulley causing belt slip)
Why it matters
An engine is one of the most expensive repairs on a riding mower. Confirming whether the real problem is starting, fuel, belt drive, or safety interlocks helps you avoid paying for an engine when a battery, solenoid, or deck belt would restore normal operation.

What kind of engine does a Craftsman riding lawn mower have?
The Craftsman riding lawn tractor model 917288522 is equipped with a low-emission gasoline engine (horsepower is listed as 21.0 HP in the operator documentation). For the exact engine make, model, and service specs, use the identification details in the 917288522 operator's manual.
How to identify the exact engine on your tractor
We recommend matching the engine ID tag on your machine to the manual’s specifications section.
- Lift the hood and locate the engine ID label (often on the blower housing or valve cover area)
- Write down the engine model, type, and code (or serial number)
- Compare those numbers to the engine information listed in the manual
- Use the engine ID when ordering tune-up parts (spark plug, air filter, fuel filter)
- If the label is dirty, wipe it clean; do not scrape it off
What we can confirm for model 917288522
Based on the operator documentation, this tractor is a Craftsman front-engine riding tractor with a low-emission gas engine and a 46-inch mower deck.
| Item | What to expect on 917288522 |
|---|---|
| Fuel type | Gasoline (up to E10 ethanol) |
| Engine type | Low-emission gasoline engine |
| Power rating shown | 21.0 HP (as rated by the engine manufacturer) |
| Mower deck size | 46 in |
Why it matters
The engine brand and exact model determine the correct maintenance parts and settings (oil type/amount, spark plug gap, air filter style). Using the engine ID prevents ordering the wrong parts and helps troubleshooting starting or performance issues.

What model number is the Craftsman 917288522?
The model number for this Craftsman front-engine lawn tractor is 917.28852 (often written without the dot as 91728852). For parts lookup and service, match the model number shown on the tractor’s ID label and in the 917288522 operator's manual.
Where to confirm the model number on your tractor
We recommend checking the tractor’s product identification label because it is the most reliable match for ordering belts, blades, and steering parts.
- Look under the seat area or on the rear fender/deck area for the ID label
- Match the full model and any product number listed
- Write down the model exactly, including any dot formatting (for example, 917.28852)
- Use the same model format when searching diagrams and parts lists
Why the number looks different (917288522 vs 917.28852)
It is common to see a longer number used for cataloging, while the operator’s manual and ID label show the “dot” model format.
| You might see | What it typically means | What to use for parts |
|---|---|---|
| 917288522 | Catalog or listing format | Use to find the correct model page |
| 917.28852 | Tractor model format shown in documentation | Use to match the ID label and manual |
Why it matters
Using the correct model format helps ensure you get the right deck and drive components for your tractor, such as the correct blade drive belt routing and the correct 46-inch deck parts.
