Does Craftsman use Kohler engines?
Yes, Craftsman uses Kohler engines on some riding mowers and tractors, but it depends on the specific model and production run. For the Craftsman lawn tractor model 9172736402, the engine details and service specs are listed in the 9172736402 owner's manual.
How to tell what engine your Craftsman tractor has
The most reliable way is to confirm the engine manufacturer and model from the tractor itself, then match it to the manual and parts diagrams.
- Check the engine ID label on the blower housing or valve cover (often shows brand and model family).
- Compare that label to the engine information section in the manual.
- Use the tractor model number 9172736402 when ordering parts to avoid mismatches.
- If you are shopping engines, match crankshaft size, mounting pattern, and PTO output.
- For tune-up parts, match the engine model (not just the tractor model).
Common engine brands you may see on Craftsman riders
Craftsman has been sold with engines from multiple manufacturers over the years. Kohler is one of them, along with other common small-engine brands.
| What you’re checking | Where to look | What it confirms |
|---|---|---|
| Tractor model | Frame tag under seat or on fender | Which parts diagrams/manual apply |
| Engine brand/model | Engine ID label | Whether it’s Kohler (or another brand) |
| Deck size/drive setup | Deck tag and belt routing | Correct blade and belt style |
Why it matters
Engine brand and model determine the correct maintenance parts (spark plug, air filter, oil filter) and the right troubleshooting steps for starting, charging, and fuel issues. Using the tractor model alone can lead to ordering the wrong engine-specific parts.

Is it worth replacing a lawn mower engine?
Yes; replacing the engine on your Craftsman lawn tractor model 9172736402 is worth it when the deck, chassis, steering, and transaxle are in good condition and the total swap cost stays well below the price of a comparable replacement tractor. If the engine job reaches about half the cost of a new tractor, replacement usually makes more sense.
Quick decision checklist
- Deck is solid (not cracked or rusted through) and can be leveled for an even cut
- Transaxle drives smoothly (no slipping, no loud grinding)
- Steering and brakes work correctly and can be adjusted
- You can service it safely (key removed, spark plug wire disconnected)
- Engine swap total (engine plus incidentals) stays under about 50% of a replacement tractor
What to check first on model 9172736402
Use the safety and troubleshooting steps in the 9172736402 owner's manual before diagnosing.
- Fuel and tune-up basics: stale fuel, dirty fuel filter, dirty air filter, low or dirty oil
- Belt and deck load: a worn blade drive belt can mimic “low power”
- Vibration sources: bent blades, loose blade bolts, worn mandrel parts
Symptom guide (often not the engine)
| What you notice | Common cause | What to do next |
|---|---|---|
| Cranks but will not start | Fuel or ignition maintenance issue | Fresh fuel, tune-up, check wiring/connections |
| Loses power while mowing | Airflow, oil, or deck drag | Clean/replace air filter, change oil, clean fins/deck |
| Excessive vibration | Blade or mandrel problem | Replace/sharpen blade, tighten hardware |
Parts often replaced during an overhaul
- Blade drive belt: Craftsman lawn tractor blade drive belt, 5/8 x 97-2/5-in 532174883
- PTO engagement switch (if blades will not rotate): switch.pto 582107601
- High-lift blade (if bent or worn): lawn tractor 42-in deck high-lift blade 532138971
Why it matters
An engine swap pays off when it restores reliable power to a safe, solid tractor; the manual’s troubleshooting chart shows many “engine” complaints are maintenance, belt, or electrical issues.

How do I find the model number on my 9172736402?
Your Craftsman lawn tractor’s model number is printed on the product identification label on the tractor frame. Once you locate it, match the full model number exactly (for example, 9172736402) when ordering parts or using diagrams in the 9172736402 owner's manual.
Where to look on the tractor
On Craftsman riding mowers and lawn tractors, the model label is typically in one of these spots:
- Under the seat on the seat pan or fender area
- On the rear fender deck near the seat
- On the frame rail under the hood (front of tractor)
- Near the engine compartment or battery area
- On the left or right side of the chassis, just above the footrest
What to write down (and why)
Record the information exactly as shown on the label; it prevents ordering the wrong blade, belt, or steering part.
- Full model number (use all digits)
- Product number or serial number (if listed)
- Engine model and type (often listed separately on the engine)
Quick ID checklist
| Item on label | Example | Why it matters |
|---|---|---|
| Tractor model number | 9172736402 | Matches the correct parts diagrams |
| Serial/product number | Varies | Helps confirm production run |
| Engine model/type | Varies | Needed for engine-specific parts |
Why it matters
Craftsman tractors can look similar across years, but parts like deck blades, mandrel assemblies, and drive belts vary by model. Using the exact model number helps ensure correct fit for items such as the Craftsman lawn tractor blade drive belt, 5/8 x 97-2/5-in 532174883 and deck components.
