What engine does Craftsman riding mower use?
The Craftsman front-engine lawn tractor model 247203743 uses a gasoline engine, but the exact engine brand, displacement, and horsepower depend on the specific engine installed on your tractor. We recommend confirming the engine model and type using the ID label and the 247203743 owner's manual.
How to identify the exact engine on model 247203743
Use these quick checks to match the correct engine and service parts:
- Look for the engine ID label on the blower housing, valve cover, or near the starter
- Record engine brand (commonly Briggs & Stratton, Kohler, or similar)
- Record the engine model and type (and code/serial if shown)
- Compare the label info to the engine section in the 247203743 owner's manual
- If the label is missing, use the tractor’s build tag and parts diagrams to narrow it down
What you can expect on a front-engine Craftsman tractor
Most front-engine Craftsman riding mowers in this class use a single-cylinder, vertical-shaft gas engine designed for mowing loads and belt-driven decks.
| Item to confirm | Where to find it | Why it matters |
|---|---|---|
| Engine brand | Engine shroud/cover label | Determines tune-up parts and specs |
| Model/type code | Engine ID label | Ensures correct carburetor, starter, and gaskets |
| Shaft orientation | Vertical shaft (typical) | Must match pulleys and deck drive |
| Charging system | Stator/regulator (varies) | Affects battery charging and no-start issues |
Why it matters
The engine model controls the correct oil type, spark plug, air filter, and fuel system parts. It also helps diagnose common problems like clicking no-starts or cranking without starting.

Is it worth replacing a lawn mower engine?
Yes, it’s usually worth replacing the engine on your Craftsman 247203743 front-engine lawn tractor when the deck, frame, steering, and transmission are still solid and the total engine job costs less than about half the price of a comparable new tractor. Use the 247203743 owner's manual to confirm engine specs and service procedures before you commit.
Quick decision checklist
- The mower deck is not rusted through and still cuts evenly
- The frame is straight and the steering is tight (no excessive play)
- The transmission drives smoothly forward and reverse
- You can get the correct replacement engine or short block for your exact setup
- You are comfortable with a moderate DIY project (wiring, fuel line, throttle/choke linkages)
- The total cost (engine + parts + your time) stays under the “50% of new” rule
Cost and effort: what to compare
| Option | Upfront cost | Time/skill | Best when |
|---|---|---|---|
| Replace engine (complete) | Higher | Moderate | You want the cleanest reset and best reliability |
| Replace short block | Medium | Higher | Top end is damaged but accessories are reusable |
| Buy new tractor | Highest | Low | Multiple systems are worn out or you need zero downtime |
What to inspect on model 247203743 before deciding
- Deck system: spindle/mandrel noise, vibration, and blade condition (a worn blade can mimic engine strain)
- Starting system: battery cables, solenoid, and safety circuits (a “bad engine” is often a no-crank issue)
- Fuel system: stale fuel, clogged filter, varnished carburetor
- Compression and smoke: heavy blue smoke or low compression points toward internal wear
If the tractor won’t crank and you only hear a click, troubleshoot the starting circuit first; the lawn tractor starter solenoid 725-06153 is a common failure point.
Why it matters
An engine swap can extend the life of a good Craftsman chassis for years, but it only pays off when the rest of the tractor is dependable. Checking the deck, drive, and electrical system first prevents spending engine money on a tractor that still won’t mow reliably.

How to look up Craftsman model number?
For Craftsman front-engine lawn tractor model 247203743, we look up the model number by finding the model and serial tag on the tractor, then using that exact model number to match the correct parts diagrams and replacement parts. The most common location is on the frame under the seat or on the underside of the seat; confirm the exact location in the 247203743 owner's manual.
Where to find the model number on a Craftsman riding mower
Check these common tag locations first (clean the area so the numbers are readable):
- On the frame under the seat (lift the seat and look on the chassis rails)
- On the underside of the seat pan
- Near the rear fender area by the seat mount
- On the frame near the engine compartment (less common)
- On a sticker or metal plate with both model and serial information
How to use the model number to look up parts
Once you have the model number, match it exactly (including dashes or extra digits) to ensure you get the right Craftsman parts list for your tractor.
| What you have | What to do | Why it helps |
|---|---|---|
| Model number (example: 247203743) | Search parts by model | Ensures diagrams and parts match your build |
| Serial number | Keep it for reference | Helps confirm production variations |
| Deck size info (if listed) | Compare to deck parts | Prevents ordering the wrong blade or belt |
If you are servicing the cutting deck, using the correct model number helps you choose the right wear items, such as the lawn tractor 46-in deck 2-in-1 blade 942-04290.
Why it matters
Craftsman tractors can look similar across years, but small differences in deck hardware, interlock wiring, and steering components can change which part fits. Using the exact model number avoids returns and gets your mower back to cutting sooner.

How to identify a lawn mower engine?
To identify the engine on your Craftsman lawn tractor model 247203743, locate the engine’s ID label or stamped code on the engine shroud (sheet metal) near the muffler and air cleaner; those numbers are what you use to match parts and service information. Use the 247203743 owner's manual for the exact label locations on your tractor.
Where to look for the engine ID
Check these common spots on front-engine riding mowers like the 247203743:
- On the sheet metal shroud directly above or near the muffler (right or left side)
- On the front of the engine near the air cleaner housing
- On a sticker or metal tag on the blower housing (the cover around the flywheel)
- Near the valve cover area (sometimes stamped into a plate or bracket)
- On the engine block casting (less common, usually harder to read)
What numbers you need (and what they mean)
Most engines use a small set of identifiers. Write them down exactly as shown.
| What you see on the engine | What it’s used for | Example format |
|---|---|---|
| Model number | Identifies the engine family | “XXXXX-XXXX” or similar |
| Type/spec code | Narrows down exact configuration | “TYPE XXXX” |
| Code/serial number | Build date and production run | “CODE XXXXXX” |
Tips to get an accurate match
These steps prevent ordering the wrong parts (especially ignition and fuel parts):
- Clean the label area first; grass dust and oil can hide digits
- Take a clear photo before you start shopping for parts
- Copy letters and dashes exactly; one character off can change the engine
- If the label is missing, use the tractor model number 247203743 to look up diagrams and compare engine components
Why it matters
The tractor model number identifies the chassis and deck, but the engine ID identifies the exact engine build. That matters for tune-up parts, starter/charging components, and fuel system parts.
