How much does it cost to replace a riding lawn mower engine?
Replacing the engine on a Craftsman 917287132 front-engine lawn tractor typically costs $900 to $2,500 installed. That total reflects a complete riding-tractor engine swap (engine plus labor) and the common add-ons needed to make the replacement reliable.
Typical cost ranges for a riding-tractor engine swap
Most shops price this job as engine cost plus 5 to 8 labor hours, plus fluids and small parts.
| Cost item | Typical range | What it covers |
|---|---|---|
| Replacement engine (part only) | $600 to $1,800 | New or reman engine matched by crankshaft size, PTO, and mounting pattern |
| Labor | $350 to $900 | 5 to 8 hours for removal, install, setup, and test run |
| Fluids and small parts | $50 to $250 | Oil, filter, fuel line/clamps, hardware, shop supplies |
| Total installed | $900 to $2,500 | Common real-world total for a riding lawn tractor |
What changes the price the most
- Exact engine match requirements: crankshaft diameter/length, keyway, and PTO setup
- Electrical condition: corroded cables, damaged wiring, weak battery
- Fuel system cleanup: stale fuel, clogged filter, dirty carburetor
- Deck and drive wear: belts and pulleys sometimes get serviced while access is easy
- Shop add-ons: pickup/delivery, disposal fees, and local labor rates
Checks to do before paying for an engine
Our experience is that many “bad engine” complaints are actually starting or fuel issues. The troubleshooting section in the 917287132 owner’s manual points you to common no-start items like the battery, wiring, fuse, ignition switch, and solenoid/starter.
- Recharge or replace the battery; clean terminals
- Inspect wiring for looseness, corrosion, or damage
- Check the fuse (if equipped)
- Verify the ignition switch output
- Test the starter solenoid and starter motor
If you get a click but no crank, the starter solenoid is a frequent fix; the lawn tractor starter solenoid 582042802 is a model-matched part option.
Why it matters
An engine replacement is one of the highest-cost repairs on a riding mower. Confirming the electrical and fuel basics first helps you avoid replacing an engine when the real problem is a solenoid, wiring, or maintenance.

How to look up Craftsman model number?
To look up the model number for your Craftsman riding mower, find the ID label on your tractor first. For Craftsman model 917287132, the model and serial tag is typically on the frame under the seat or on the underside of the seat; then use that exact number to match parts and diagrams in the 917287132 owner's manual.
Where to find the model and serial number
Check these common locations on Craftsman front-engine lawn tractors:
- On the frame directly under the seat (lift the seat to view)
- On the underside of the seat pan
- Near the rear fender area close to the seat mounting points
- On a sticker or metal tag attached to the chassis rail
How to use the model number to look up parts
Once you have the model number, use it exactly as printed (including dots and digits) to ensure the correct parts list for your tractor-series DLS3500.
- Match the model number first, then confirm the product type (riding mower/tractor)
- Use the parts diagrams to identify the exact component name
- Cross-check the part description before ordering
- If you are servicing the mower deck, confirm deck size (many are 46-inch on this series)
Quick example: model number vs. part identifiers
| What you see | Example | What it’s used for |
|---|---|---|
| Model number | 917287132 | Selects the correct tractor parts breakdown |
| Part ID | 584453101 | Identifies a specific part listing |
| Part number | 405143 | Manufacturer number used for compatibility |
Why it matters
Using the exact Craftsman model number prevents ordering the wrong belt, blade, or electrical part. Even similar-looking tractors can use different deck drive systems, mandrel assemblies, or wiring harnesses.
If you are troubleshooting a deck that will not engage or a belt that keeps slipping, the parts list for model 917287132 helps you match common wear items like the husqvarna lawn tractor blade drive belt 584453101 to the correct deck configuration.

What model number is the Craftsman 917287132 engine?
The engine on a Craftsman 917287132 lawn tractor does not use the tractor’s model number as its engine model number. For the correct engine model and specification numbers, we use the engine ID label on the engine itself and confirm it against the 917287132 owner's manual.
Where to find the engine model number
On Craftsman riding mowers, the engine model is listed on the engine manufacturer’s ID label (not on the hood or tractor frame tag).
- Look on top of the engine shroud (blower housing) near the recoil starter area
- Check the valve cover area or near the spark plug
- Look near the muffler heat shield (often on a sticker or metal tag)
- Clean the area first; grass dust and oil film can hide the numbers
- Write down model, type/spec, and code/serial exactly as shown
What numbers you should record (and why)
Different engines can be used across similar tractor platforms, so we match parts by the engine’s full ID.
| Label item | What it tells us | Used for |
|---|---|---|
| Engine model | Engine family and displacement | Tune-up and internal parts |
| Type/spec | Exact build configuration | Carburetor, ignition, governor parts |
| Code/serial | Production date/run | Correct revisions and supersessions |
Quick checks if you are shopping for parts
If your goal is to buy common maintenance parts, we typically start with the tractor model 917287132, then confirm the engine ID to avoid mismatches.
- Air filter and pre-filter
- Spark plug
- Fuel filter
- Oil filter (if equipped)
- Starter and electrical parts
If the tractor will not crank, a common electrical part to verify is the lawn tractor starter solenoid 582042802.
Why it matters
Using the tractor model number alone can lead to the wrong engine parts because the tractor model identifies the chassis and mower deck system, while the engine model identifies the exact engine build.
