How many horsepower is a 547cc motor?
A 547cc engine is typically about 18 to 20 horsepower on riding mowers, depending on the engine design and the RPM where it’s rated. Your Craftsman model 917254710 is a 14 HP, 38-inch riding tractor; we recommend using the rating shown in the owner's manual for your exact mower.
Why cc and horsepower do not match 1:1
Engine displacement (cc) measures cylinder volume; horsepower measures power output at a specific RPM. Two engines with the same cc can have different horsepower because of:
- Rated RPM and governor setting
- Compression ratio and combustion design
- Carburetor and intake/exhaust tuning
- Emissions calibration
- How the manufacturer reports “gross” vs “net” power
Quick reference: what 547cc usually means on a riding mower
These ranges are practical, real-world expectations for lawn tractor engines:
| Engine size (cc) | Typical horsepower range | Common application |
|---|---|---|
| 400 to 500cc | 12 to 18 HP | 38 to 42-inch decks, lighter loads |
| 547cc | 18 to 20 HP | 42 to 46-inch decks, heavier mowing |
| 600 to 725cc | 20 to 26 HP | larger decks, hills, towing |
How to confirm the correct horsepower for your mower
For Craftsman 917254710, the most accurate way is to confirm the engine model and the mower’s stated rating:
- Check the hood decal or frame label for the mower’s HP rating
- Check the engine shroud for the engine model and type
- Match the engine model to the specifications section in the owner's manual
- If you are troubleshooting performance, verify the air cleaner and fuel delivery are clean and unrestricted
Why it matters
Using the correct horsepower rating helps you choose compatible parts and set realistic expectations for mowing speed, hill performance, and towing. It also prevents ordering the wrong drive components when diagnosing slipping or weak drive.
If you are chasing a drive issue (loss of ground speed, slipping under load), a worn ground drive belt is a common cause; the v-belt 532125907 is one of the model-matched options listed for this tractor.

Who makes the 547cc IntelliPOWER engine?
The Craftsman 917254710 38-inch 14-hp riding tractor uses a Briggs and Stratton engine (manual lists engine model 400707, type 1507-01); it is not a 547cc IntelliPOWER engine. For the exact engine identification details and parts breakdown, use the owner's manual.
How to confirm the engine maker on your tractor
We recommend verifying the engine ID on the engine itself, then matching it to the tractor documentation.
- Look for the engine label on the blower housing or valve cover area
- Record the engine model, type, and code (Briggs and Stratton uses all three)
- Compare those numbers to the engine section in the owner's manual
- Use the tractor model number 917254710 when ordering chassis or deck parts
- Use the engine model/type when ordering engine-specific parts (air cleaner, carburetor, starter)
What the manual shows for model 917254710
The manual’s engine parts pages identify the engine as Briggs and Stratton and list the engine model and type.
| Item | What to look for | What it tells you |
|---|---|---|
| Tractor model | 917254710 | Which Craftsman chassis/deck you have |
| Engine maker | Briggs and Stratton | Who manufactured the engine |
| Engine model/type | 400707 / 1507-01 | Which engine parts diagram applies |
Why this matters when buying parts
Engine branding and displacement terms (like “547cc IntelliPOWER”) are used on some newer riding mowers, but parts ordering depends on the exact engine model/type and the exact tractor model. Using the correct IDs prevents mismatched belts, pulleys, and engine service parts.
If you are ordering common tractor wear items, you can also shop by model and parts diagram on this page, or search more broadly on Sears PartsDirect.

What model number is the Craftsman 42 riding mower?
For the Craftsman model page you’re on, the correct model number is 917254710, and it’s a 14 HP 38-inch front-engine riding yard tractor (not a 42-inch mower). For exact deck size and identification details, use the owner's manual.
How to confirm the model number on your mower
We recommend matching the model number on the tractor’s ID label to the manual and parts diagrams.
- Look for the product ID label under the seat, on the frame rail, or near the engine
- Confirm the model number is 917254710 (numbers and punctuation must match)
- Compare the deck size listed on the label (this model uses a 38-inch mower deck)
- Use the manual’s repair parts section to match assemblies like the 38-inch mower deck
- If your label shows a different model, use that exact number when ordering parts
38-inch vs 42-inch: what’s different
A “42-inch Craftsman riding mower” is a different configuration than model 917254710. The deck size affects belt length, blade set, spindle parts, and deck hardware.
| Item | Model 917254710 (this page) | Typical 42-inch mower |
|---|---|---|
| Deck size | 38-inch | 42-inch |
| Belt fit | 38-inch deck belt routing and length | Different belt length and routing |
| Parts lookup | Use 917254710 diagrams | Use the exact 42-inch model number |
Why it matters for parts and repairs
Using the wrong model number is the fastest way to end up with a belt, pulley, or safety switch that does not fit. For example, this model’s parts list includes items like the lawn tractor blade drive belt 532106085 and the lawn tractor seat switch 532421062, which are selected to match the 38-inch deck and this tractor’s interlock system.
Ordering the right parts
We recommend ordering replacement parts from the parts list for Craftsman 917254710; for broader model searches, use Sears PartsDirect.

How to tell what year a Craftsman mower is?
For a Craftsman riding tractor like model 917254710, the year is identified from the tractor’s ID label using the serial number (not the model number alone). Find the ID label, record the full serial exactly, then use the identification guidance in the 917254710 owner's manual.
Where to find the ID label
On most Craftsman front-engine lawn tractors, the ID label is typically located in one of these places:
- Under the seat pan or on the seat support
- On the rear fender pan near the seat
- On a frame rail near the engine
- Under the hood near the dash tower
How to use the numbers you find
Use the model number to confirm the correct parts diagrams, then use the serial number to narrow down production details.
- Model number (917254710): identifies the tractor family and parts breakdown
- Serial number: ties to the build run and is the best clue to the year
- Engine date stamps: can differ if the engine was replaced
What to write down (exactly)

|---|---|---|
| Model number | 917254710 | Confirms the correct parts list |
| Serial number | (from ID label) | Used to determine build year/run |
Why it matters for repairs and parts
Craftsman tractors can look similar across multiple years, but deck linkage and belt routing can change. Matching by model and serial helps you avoid ordering the wrong belt length or hardware.
If you are ordering common wear items, match them to the diagrams for model 917254710; for example the lawn tractor blade drive belt 532106085 or the lawn tractor seat switch 532421062. For broader parts searching by model number, use Sears PartsDirect.
