What engine does Craftsman riding mower use?
For Craftsman lawn tractor model 917274352, the owner's manual identifies it as a low-emission, electric-start tractor and lists it as a 16.0 HP, 42-inch mower setup. For the exact engine manufacturer and model designation, use the engine ID label and the specifications section in the 917274352 owner's manual.
How to identify the exact engine on your tractor
Even within the same tractor model, the engine brand and spec code are confirmed by the engine’s ID tag (not the mower deck size).
- Look for an engine label on the blower housing, valve cover, or near the starter
- Record the engine model, type, and code/spec numbers
- Match those numbers to the engine parts list when ordering tune-up parts
- Use the tractor model number 917274352 when ordering chassis, deck, and drive parts

How much does it cost to replace a riding lawn mower engine?
For a Craftsman riding lawn tractor like model 917274352, a full engine replacement typically runs about $260 to $1,800 installed, depending on the engine type, labor rates, and whether related items (belts, pulleys, wiring) need attention during the swap. Confirm the exact engine spec and procedures in the 917274352 owner's manual.
What drives the total price
- Engine cost: the biggest variable (new vs. remanufactured, horsepower, shaft size)
- Labor time: commonly 4 to 8 hours for a riding mower engine swap
- Extra parts: fuel line, clamps, battery cables, mounting hardware, or a worn drive belt
- Shop fees: pickup/delivery, diagnostics, disposal
- Condition of the tractor: rusted fasteners and damaged wiring increase labor
Typical cost breakdown
| Cost item | Typical range | Notes |
|---|---|---|
| Engine (part only) | $200 to $1,500 | Varies by brand, power, and configuration |
| Labor | $200 to $800 | Based on hourly rate and time |
| Misc. parts/fluids | $20 to $150 | Oil, filter, fuel line, hardware |
| Total installed | $260 to $1,800 | Most jobs land in the middle |
Before you replace the engine
We recommend ruling out common “no start” causes first, because they can look like a bad engine.
- Check battery charge and cable connections
- Verify the safety interlock system is working (seat, brake, PTO)
- Inspect fuel quality and the fuel filter
- Check spark plug condition and ignition spark
- Confirm the engine turns freely by hand (with the key removed)
A helpful walkthrough is riding lawn mower engine spins but wont start video.
Why it matters
An engine replacement can cost close to the value of an older riding mower. Pricing the engine plus labor up front helps you decide whether to repair, rebuild, or invest in other maintenance items (like blades and belts) to extend the tractor’s service life.

Who makes the Craftsman 420cc engine?
For Craftsman tractor model 917274352, the owner’s manual lists a 16.0 HP, 42-inch mower tractor and does not describe it as a 420cc engine. To identify who made the engine on your specific tractor, use the engine’s model and spec numbers and cross-check them in the 917274352 owner’s manual.
How to identify the engine manufacturer on 917274352
Use the engine ID tag on the engine itself; that tag identifies the actual engine maker and exact build.
- Find the engine ID label on the blower housing, valve cover, or near the starter
- Record the full engine model, type, and code/spec numbers
- Match those numbers to the engine information and maintenance section in the 917274352 owner’s manual
- If the tractor has had an engine swap, trust the engine tag (not the tractor model number)
- Use the engine model/spec to select the correct air filter, spark plug, and fuel system parts
What “420cc” means (and what it does not)
“420cc” is engine displacement; it does not confirm the manufacturer by itself. Different makers can build engines with similar displacement.
| Identifier | What it tells you | Best use |
|---|---|---|
| Tractor model 917274352 | Tractor platform and parts fitment | Deck, chassis, steering, electrical parts |
| Engine model/type/code | Engine manufacturer and exact build | Tune-up parts, carburetor, ignition, starter |
| “420cc” | Displacement only | General comparison, not parts ordering |
Why it matters
Ordering engine parts by displacement alone often leads to wrong filters, carburetors, or ignition components. Using the engine model/type/code ensures the correct fit and speeds up troubleshooting for no-start, hard-start, and poor-running issues.

What year was Craftsman 917274352 made?
Craftsman model 917274352 is a front-engine lawn tractor; the documentation for this model identifies assemblies and parts lists but does not publish a single “model year.” To date your tractor accurately, we use the serial number (and any date code) from the product label and confirm configuration details in the 917274352 owner's manual.
How to find the manufacture date information
On most Craftsman riding mowers and tractors, the best dating info is on the tractor’s product label.
- Check under the seat, on the frame rail, or near the rear fender
- Record the model number (917274352) and the serial number exactly
- Look for a printed date code, DOM, or similar marking on the label
- If the tractor label is missing, record the engine model/type/code from the engine shroud
- Use the parts diagrams in the manual to match your deck and chassis configuration
What the manual confirms for this model
The manual for model 917274352 confirms key assemblies that help you match the correct production run when you compare your tractor to the illustrated parts lists.
| Manual section | What it helps confirm | Example shown for 917274352 |
|---|---|---|
| Mower deck breakdown | Deck size and blade listings | 42-inch mower deck assembly and blade options |
| Chassis and enclosures | Frame and hood family | Chassis, drawbar, hood assembly listings |
| Engine section | Engine identification used on this tractor | Engine model listing appears in the engine breakdown |
Blade note (to avoid ordering the wrong size)
This tractor uses a 42-inch deck, so blade selection must match the 42-inch deck specification.
- A 42-inch deck typically uses two blades
- A “42-inch deck blade” is not the same as a “21-inch blade” unless the deck specifically calls for that size
- The lawn tractor 42-in deck high-lift blade 532138971 is a 42-inch deck blade option listed for this model
- The husqvarna lawn tractor mulching blade, 21-in 532134149 is a 21-inch blade; only use it if your deck/blade listing specifically calls for a 21-inch blade
Why it matters
The “year” matters mainly because parts can change during a model’s production. Matching by model plus serial (and confirming deck and engine details) prevents wrong-part returns for belts, blades, mandrel parts, and steering components.
