What kind of engine does a Craftsman riding lawn mower have?
The Craftsman riding lawn mower model 917288570 is equipped with a 24.0 HP engine (as rated by the engine manufacturer) and is labeled as a low-emission engine. The exact engine brand and model family are not identified by the model-specific information we have for this tractor.
How to confirm the exact engine on your tractor
The most reliable way is to read the engine identification label on the engine itself (not the tractor model tag). Use the steps and diagrams in the 917288570 operator's manual to locate service points and follow safe access procedures.
- Lift the hood and look for an engine label or stamped tag
- Record the engine model, type, and code (or serial)
- Match those numbers when ordering engine-specific parts (spark plug, air filter, fuel filter)
- If the label is dirty, wipe it gently so the numbers are readable
- Use the tractor model number 917288570 for chassis/deck parts, not engine internals
Model-specific specs we can confirm for 917288570
From the operator information for this model, we can confirm several engine-related service specs even without the engine brand.
| Spec (917288570) | Value |
|---|---|
| Engine power rating | 24.0 HP (manufacturer-rated) |
| Fuel type | Unleaded regular |
| Fuel capacity | 3.0 gallons |
| Spark plug | Champion QC12YC (0.040 in gap) |
Why it matters
Engine brand and model determine the correct tune-up parts and settings. The tractor model 917288570 helps us match deck, drive, steering, and chassis components, but the engine ID is what ensures you get the right maintenance parts for starting, power, and fuel efficiency.
If you’re troubleshooting loss of power when mowing, a worn blade belt can also be a factor; see the husqvarna lawn tractor blade drive belt 584453101 if you need a compatible replacement for this model.

Is it worth replacing a lawn mower engine?
For the Craftsman 917288570 front-engine lawn tractor, replacing the engine is usually worth it only when the tractor is otherwise in solid condition and the total repair cost stays below about half the price of a comparable replacement tractor. If the transmission, deck, or frame also need major work, replacement is typically the better value.
Quick decision checklist (Craftsman 917288570)
- Replace the engine if the deck cuts well, the transmission drives smoothly, and the chassis is not heavily rusted or damaged.
- Skip the engine swap if you also have slipping drive, major deck damage, or repeated electrical issues.
- Consider repair instead of replacement if the problem is fuel, ignition, or maintenance related (not internal engine failure).
- Factor in downtime: engine swaps can take time for parts matching, setup, and adjustments.
- Confirm specs first using the Craftsman 917288570 operator’s manual.
Costs and value: what to compare
Use this simple comparison to decide:
| Item to compare | What to estimate | What it tells you |
|---|---|---|
| Tractor replacement cost | Price of a similar 46-inch riding mower | Your “ceiling” for repairs |
| Engine replacement total | Engine + mounting/hardware + labor | True out-of-pocket cost |
| Other near-term repairs | Belts, blades, spindles, battery, tires | Whether more money is coming soon |
If your deck or drive system needs work anyway, pricing common wear parts can help you judge the full picture, such as a husqvarna lawn tractor blade drive belt 584453101 or a husqvarna lawn tractor 46-in deck high-lift blade 532405380.
Why it matters
An engine replacement can restore power and reliability, but it does not fix worn deck components, belt routing issues, or transmission wear. On a tractor like the 917288570, the best value comes from putting money into a machine that is structurally sound and still has a strong drive and cutting system.

Who makes Craftsman engines?
For Craftsman lawn tractor model 917288570, the engine is made by Briggs & Stratton. Craftsman is the tractor brand; the engine brand is identified on the engine itself and in the tractor documentation.
How we confirm the engine maker on model 917288570
The most reliable confirmation is the engine identification label and the tractor documentation.
- Look for a Briggs & Stratton label on the engine shroud or valve cover
- Record the engine model, type, and code numbers for parts matching
- Use the tractor documentation for safe access and basic identification steps
- Match tune-up parts (spark plug, air filter, oil filter) to the engine numbers, not just the tractor model
Reference: 917288570 operator's manual
Where to find the engine ID tag
On most Briggs & Stratton riding mower engines, you’ll find the ID in one of these places:
- On top of the engine shroud
- On the valve cover
- Near the spark plug area
- Stamped into the blower housing or engine block
- On a sticker under the hood near the engine
Why it matters
Briggs & Stratton engine identification determines the correct maintenance specs and replacement parts (oil type, spark plug gap, filters). Using only the tractor model number can lead to mismatched engine parts.
