What kind of engine does a Craftsman riding lawn mower have?
The Craftsman riding lawn mower model 917289223 uses a low-emission, internal-combustion gasoline engine; the operator’s manual for this model does not identify the exact engine brand or cylinder configuration. For the correct engine details, we match by the tractor’s model and the engine’s own model/type code. See the 917289223 operator’s manual.
We recommend checking the engine label on the tractor itself; that label is the most reliable way to confirm the engine family and service parts.
- Lift the hood and look for an engine ID label on the blower housing or valve cover
- Record the engine model, type, and code (sometimes shown as model-type-code)
- Use that engine ID when buying tune-up parts (spark plug, air filter, oil filter, fuel filter)
- If the label is hard to read, wipe it clean and take a clear photo before ordering parts
- Keep the tractor model number 917289223 handy because it helps confirm the correct chassis and deck parts
Based on the documentation for Craftsman model 917289223, we can confirm these engine-related specs and requirements:
| Spec (from manual) | Value |
|---|---|
| Fuel type | Unleaded regular gasoline |
| Fuel capacity | 2.50 gallons |
| Oil type (by temperature) | SAE 30 (above 32°F), SAE 5W30 (below 32°F) |
| Spark plug | Champion RC12YC (0.030 in gap) |
The engine brand and model determine the correct maintenance parts and settings. Using the engine’s model/type code helps prevent ordering the wrong spark plug, air filter, or fuel system parts, and it supports easier troubleshooting if the tractor won’t start.

How to find Craftsman model number?
For a Craftsman riding mower like model 917289223, we typically find the model number on a product label under the seat area (often on the frame under the seat, or on the underside of the seat). Once you have it, match parts and diagrams using the exact model number. For label examples and tractor-specific details, use the 917289223 operator's manual.
Check these common label locations first (clean off grass and dirt so the numbers are readable):
- On the frame under the seat (lift the seat up)
- On the underside of the seat pan
- Near the rear fender area close to the seat mounting points
- On the chassis rail near the battery or rear wheels (varies by build)
- On a sticker or metal tag that includes both model and serial information
Craftsman riding mower model numbers are usually a 9-digit format. For this tractor, the model family is shown as 917.28922 in the manual, and the full model used for parts lookup is 917289223.
| What you see | What it’s used for | Example for this tractor |
|---|---|---|
| Model number | Identifies the exact parts breakdown | 917289223 |
| Serial number | Identifies production run details | Varies |
Even one digit off can change the deck, belt routing, or electrical components.
- Write the model number exactly as printed (include all digits)
- If the label is worn, take a clear photo and zoom in
- Use the model number (not the engine brand) to match tractor parts
- Confirm deck size and blade style before ordering cutting parts
We use the model number to match the correct diagrams and compatible replacement parts for your Craftsman tractor, including belts, blades, pulleys, and safety switches.

How much does it cost to replace a riding mower engine?
Replacing the engine on a Craftsman riding lawn tractor like model 917289223 is usually a major repair; a typical total is $900 to $2,500 for the engine plus labor, with the final price driven by the exact replacement engine and local shop rates.
The operator’s manual for model 917289223 focuses on operation, maintenance, and troubleshooting; it does not list engine replacement pricing or a specific engine cost. For model-specific maintenance steps that can help prevent engine damage, use the 917289223 owner’s manual.
Most engine-swap estimates change because of these factors:
- Replacement engine choice: new, rebuilt, or used
- Labor time: removal, mounting, wiring, throttle/choke setup, and test run
- Extra parts needed: belts, pulleys, fuel line clamps, battery cables, or hardware
- Reason for failure: overheating, oil starvation, or internal damage can add cleanup and repairs
- Shop minimums and pickup/delivery: common with riding mowers
| Scenario | What’s included | Typical total |
|---|---|---|
| Repair instead of replace | Fuel/ignition work, tune-up, minor fixes | $150 to $700 |
| Replace engine | Engine + installation + setup | $900 to $2,500 |
| Replace engine plus related wear items | Engine + installation + belts/pulleys/controls as needed | $1,100 to $3,000 |
Even if you only replace the engine, we often recommend checking these wear items because they can affect performance and reliability:
- Deck and drive belts for cracking or glazing
- Idler pulleys for bearing noise or wobble
- Fuel cap venting and fuel line clamps for leaks
- Wiring connections and safety interlock circuits
If your tractor also has drive or blade issues, inspecting the lawn tractor ground drive or blade drive belt, 1/2 x 92-2/5-in 592855201 can be a practical first step (only replace it if it matches your tractor’s belt routing and length).
An engine swap can approach the value of an older tractor. Comparing the engine-swap total to the condition of the mower deck, transmission, steering, and electrical system helps you decide whether repair or replacement makes more sense.
