How to look up Craftsman model number?
To look up your Craftsman model number for parts and manuals, find the model/serial tag on your tractor and match the model number exactly (for this unit, it is 917273760). Once you have it, use it to pull the correct diagrams, maintenance info, and replacement parts in the 917273760 owner's manual.
Where to find the model number on a Craftsman riding mower
Most Craftsman riding mowers and lawn tractors place the model/serial label in one of these spots:
- 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 close to the seat mounting points
- Occasionally on the frame near the engine compartment (less common)
How to read the tag so you get the right parts
Write down the information exactly as shown on the label.
- Model number: use all digits (example: 917273760)
- Serial number: helps identify production run details
- Product name/type: “lawn tractor” or “riding mower”
- Engine info: useful for engine-specific parts (filters, spark plug, etc.)
Quick check table
| What you see on the tag | What to do with it | Why it helps |
|---|---|---|
| Model number (917.273760 or 917273760) | Enter it without spaces | Pulls the correct parts diagrams |
| Serial number | Keep for reference | Helps confirm exact build |
| Deck size / HP (example: 42 in, 18.0 HP) | Use as a cross-check | Prevents ordering the wrong blade or belt |
Why it matters
Craftsman tractors often share similar frames and decks across multiple models. Using the exact model number ensures you get the correct items like blades, belts, mandrel parts, and steering components.
Example of a model-matched part
If you are shopping for mower deck blades for this model, use model-based diagrams to confirm fit before ordering a blade such as the lawn tractor 42-in deck high-lift blade 532138971.

What brand engine does Craftsman use?
Craftsman uses engines from multiple manufacturers depending on the tractor and production run. For the Craftsman lawn tractor model 917273760, the engine is an 18.0 HP low-emission internal combustion engine; the exact engine brand is identified in the model’s documentation and engine labeling (see the 917273760 owner's manual).
How to identify the engine brand on model 917273760
Use these quick checks to confirm what your tractor has:
- Check the engine shroud or valve cover for a brand badge (commonly Briggs & Stratton, Kohler, or Kawasaki on many Craftsman tractors).
- Look for an engine model/type code sticker near the starter, blower housing, or valve cover.
- Match the engine model code to the engine parts list in the 917273760 owner's manual.
- If decals are missing, use the tractor model number 917273760 plus the engine model code when ordering parts.
- If the engine cranks but will not start, follow the no-start diagnostics in riding lawn mower engine spins but wont start video.
Common engine brands used on Craftsman lawn tractors
Craftsman has historically sourced engines from several major small-engine makers. Which one you have depends on the specific tractor model and year.
| Engine brand | Where you’ll usually see it | What to record for parts |
|---|---|---|
| Briggs & Stratton | Engine shroud label, stamped model-type-code | Model, type, code |
| Kohler | Valve cover/shroud tag | Spec number, serial |
| Kawasaki | Shroud tag near recoil/starter area | Model, spec, serial |
Why it matters
The engine brand and engine model code determine the correct tune-up parts (air filter, spark plug, fuel filter) and service specs (oil type/quantity, valve settings). Using the tractor model number alone can lead to the wrong engine parts.

How to identify a lawn mower engine?
On the Craftsman lawn tractor model 917273760, we identify the engine by locating the engine identification numbers (model, type, and code) stamped on the engine itself. The most common locations are on the blower housing (shroud) near the muffler or on a label near the air cleaner; confirm the exact location using the 917273760 owner's manual.
Where to look on the tractor
Check these spots first (wipe off grass and oil so the stamp is readable):
- On the sheet metal shroud directly above or near the muffler (right or left side)
- On the front face of the engine, between the air cleaner and other engine markings
- On a sticker or metal tag near the air cleaner housing
- Near the starter area on the engine block (less common)
What numbers you need (and why)
Most small engines use a few identifiers. Write them down exactly as shown.
| What you see | What it’s used for | Example format |
|---|---|---|
| Engine model/type | Ordering engine-specific parts | 12Axxx-xxxx |
| Code/date | Determining production version | YYMMDDxx |
| Spec/trim | Matching carburetor, ignition, governor parts | Spec #### |
Tips to get a clean, readable ID
- Turn the key to STOP, remove the key, and let the engine cool
- Use a flashlight and take a photo, then zoom in
- Clean gently with a rag and mild degreaser; avoid scraping the stamp
- Copy letters and numbers exactly (including dashes)
Why it matters
The tractor model 917273760 tells us the chassis and deck family (for example, 42-inch mower setup), but the engine ID is what matches tune-up parts like the air filter, spark plug, fuel filter, and carburetor components.

Is it worth replacing a lawn mower engine?
Yes, it’s worth replacing the engine on your Craftsman lawn tractor model 917273760 when the tractor’s deck, transmission, and frame are in solid condition and the total engine swap cost stays well below the cost of a comparable replacement tractor. If the tractor has multiple worn systems, replacement is usually the better value.
How we decide if an engine swap makes sense
- The mower deck is not rusted through and still cuts evenly after leveling
- The transmission and drive system move smoothly (no slipping, no grinding)
- Steering and brakes operate correctly (the manual recommends checking brake operation frequently)
- You can source the correct engine and any required pulleys, belts, or wiring adapters
- The total parts plus labor cost stays under about half the price of a similar new riding mower
For model-specific maintenance and safety steps (including servicing guidance and safety warnings), use the 917273760 owner’s manual.
Cost and effort comparison
| Option | Typical cost | Time/skill | Best when |
|---|---|---|---|
| Repair existing engine (tune-up, carb clean) | Low | Moderate | It cranks and runs poorly, or starts then dies |
| Replace engine (complete swap) | Medium to high | High | Engine is seized, thrown rod, or low compression |
| Replace tractor | High | Low | Deck, steering, and drive system are also worn |
Before you replace the engine, rule out common “no start” causes
Many “bad engine” symptoms are actually basic fuel, ignition, or electrical issues. The manual’s troubleshooting points to items like the air filter, spark plug, battery, fuel filter, and wiring.
- Verify the brake pedal is fully depressed and the attachment clutch is disengaged
- Check battery condition and clean battery terminals
- Inspect wiring connections at the ignition switch, solenoid, and starter
- Replace the spark plug and confirm the spark plug wire is tight
- Refresh fuel (drain old gas, refill with fresh gasoline)
If the tractor only clicks or spins but won’t start, follow riding lawn mower engine clicks but doesnt turn over video and riding lawn mower engine spins but wont start video.
Why it matters
An engine replacement can extend the life of a good Craftsman chassis for years, but it only pays off when the rest of the tractor is dependable. Otherwise, you risk putting a new engine into a mower that still needs blades, belts, mandrel work, or steering repairs soon after.
