How many horsepower is a 420cc Craftsman engine?
On the Craftsman lawn tractor model 917287460, the operator’s manual identifies the tractor as a 26.0 HP model. For a “420cc Craftsman engine” in general, horsepower varies by engine design and tune, but this specific tractor is marketed and labeled as 26.0 HP in its documentation.
How to confirm the horsepower on your exact tractor
We recommend matching the horsepower to the tractor’s model label and the specifications section in the documentation.
- Check the hood decals and the model tag for the HP rating.
- Verify the model number is 917287460 (not a close variant).
- Use the product specifications section in the 917287460 owner’s manual.
- If you are comparing engines, use the engine model/type on the engine shroud, not just “420cc.”
- Keep in mind that “cc” (displacement) does not convert to one fixed horsepower number.
420cc vs horsepower: what’s typical
Displacement is only one piece of the performance picture. Horsepower changes with RPM rating, carburetion/fuel system, emissions tuning, and how the manufacturer measures and labels output.
| What you have | What it tells you | What it does not tell you |
|---|---|---|
| 420cc displacement | Engine size (volume) | Exact horsepower |
| HP label on tractor | The marketed rating for that tractor | Engine-to-engine comparability across brands |
| Engine model number | Best way to match parts and specs | A universal HP conversion |
Why it matters
Using the correct horsepower rating helps when you are selecting maintenance parts (spark plug, oil type, belts) and when you are troubleshooting performance issues like bogging, hard starting, or poor cutting under load.

What are the parts of a tractor engine?
On the Craftsman 917287460 front-engine lawn tractor, the engine is built from core internal parts (like the cylinder, piston, and crankshaft) plus support systems (fuel, ignition, lubrication, and cooling). For your exact engine layout and service points, use the 917287460 owner's manual.
Main tractor engine parts (what they do)
- Cylinder block and cylinder head: form the combustion chamber and support valves
- Piston, piston rings, and wrist pin: compress the air-fuel mix and transfer force to the rod
- Connecting rod and bearings: link piston motion to the crankshaft smoothly
- Crankshaft and flywheel: convert up-and-down motion into rotation that drives the tractor
- Valves, valve springs, and guides: control intake and exhaust flow
- Camshaft and lifters: time valve opening and closing
Engine support systems you will service most often
- Fuel system: fuel tank, fuel line, filter, carburetor or injection components
- Ignition system: ignition switch, safety interlocks, coil, spark plug
- Lubrication system: oil sump, oil pump (on some engines), oil filter (if equipped)
- Air intake: air filter and housing
- Starting/charging: battery, starter, solenoid, alternator/stator
Quick reference: internal vs. external engine parts
| Group | Examples | Typical symptoms when worn |
|---|---|---|
| Internal rotating | crankshaft, connecting rod, bearings | knocking, low power, metal in oil |
| Internal sealing | piston rings, head gasket, valve seals | smoke, low compression, hard starting |
| External service items | spark plug, air filter, oil | rough running, stalling, poor starting |
Why it matters
Knowing which system a part belongs to helps you troubleshoot faster. For example, a no-start is often ignition, fuel, or starting circuit related, while smoke and low power usually point to compression or lubrication issues.
Helpful tip for this model
The manual calls out routine maintenance items as normal wear parts (such as spark plugs, air cleaners, belts, and oil filters), so keeping up with tune-ups prevents many “engine” problems from starting in the first place.
