Does Craftsman use Kohler engines?
Yes. Craftsman uses Kohler engines on some lawn tractors, and the Craftsman lawn tractor model 917273663 is equipped with a Kohler CV730 engine (type 0028) per the 917273663 owner's manual.
When your tractor has a Kohler engine, you typically match engine parts (like ignition and starting components) to the Kohler engine model, and tractor parts (like belts, pulleys, and chassis hardware) to the Craftsman model number.
- Use the tractor model (917273663) for deck, drive, steering, and chassis parts
- Use the engine model (Kohler CV730) for engine-specific items (spark plugs, starter/solenoid, charging parts)
- Confirm the engine model and type before ordering engine parts
- Follow the maintenance schedule and oil recommendations in the manual
| What you are working on | Identify it by | Example for this model |
|---|---|---|
| Mower/tractor frame and drive system | Craftsman model number | 917273663 |
| Engine components | Kohler engine model and type | CV730, type 0028 |
If you are troubleshooting a no-start, no-crank, or charging problem, you are usually in “engine parts” territory.
- Engine clicks but will not turn over
- Engine spins but will not start
- Battery not charging while running
- Starter/solenoid problems
- Ignition/electrical concerns
For step-by-step troubleshooting, use riding lawn mower engine clicks but doesnt turn over video.
Kohler engine model numbers help prevent wrong-part orders. On model 917273663, knowing it uses a Kohler CV730 lets you match the correct ignition/electrical and starting-system components when servicing the tractor.

How much does it cost to replace a riding lawn mower engine?
For the Craftsman lawn tractor model 917273663, a full engine replacement typically runs $260 to $1,800 installed, depending on the engine, labor rates, and any extra parts needed (belts, pulleys, wiring). Plan on about 6 hours of labor for a riding mower engine swap.
- Engine price (new vs. rebuilt, horsepower, crankshaft specs)
- Labor rate (shop minimums and regional pricing)
- Extra parts discovered during teardown (worn belts, damaged pulleys, loose hardware)
- Fuel system cleanup (old fuel, clogged lines, dirty tank)
- Electrical/safety circuit issues that show up after installation
| Cost item | Typical range | Notes |
|---|---|---|
| Replacement engine | $200 to $1,400 | Biggest variable; must match mounting and crank specs |
| Labor (riding mower) | $200 to $600 | Often ~6 hours total |
| Misc. parts/fluids | $20 to $200 | Oil, filters, belts, fasteners |
If the old engine failed violently, overheated, or threw a belt, we often see related wear in the drive and deck system. These are common “while you are in there” items for this model:
- Lawn tractor ground drive belt, 1/2 x 82-in 532140294 (if the tractor drive belt is worn or glazed)
- Lawn tractor engine pulley 532174607 (if the pulley is wobbling or the bore is damaged)
- Lawn tractor blade idler pulley 532177968 (if the deck belt system is noisy or rough)
An engine replacement only pays off when the rest of the tractor is in solid shape. If the transmission, deck mandrels, or chassis are heavily worn, the better value can be repairing the existing engine or addressing the root cause (overheating, lack of oil, fuel contamination) before installing a new one.
Use the 917273663 owner’s manual to verify the tractor’s configuration and maintenance requirements, then match the replacement engine by mounting pattern and crankshaft dimensions.

How do I find the model number on my 917273663?
The model number for your Craftsman lawn tractor is printed on the product identification label; for this tractor it’s 917.273663 (often shown as 917273663 online). Use the label number when ordering parts and matching diagrams in the owner's manual.
On Craftsman riding mowers and lawn tractors like model 917273663, the ID label is typically in one of these spots:
- Under the seat (lift the seat and look on the seat pan or frame)
- On the rear fender/footrest area near the seat
- On the frame rail near the engine compartment
- Near the transaxle area on the frame (rear of tractor)
Craftsman tractor model numbers are commonly formatted with a dot:
| You might see it as | It means |
|---|---|
| 917.273663 | Model number (same tractor) |
| 917273663 | Same model number without the dot (common online) |
- Wipe dirt and grass off the label so all digits are readable
- Write down the full model number exactly as shown
- If the label also lists a serial number, record it for your own reference
- Use the model number to confirm part diagrams before replacing belts, pulleys, or electrical parts
The model number ties your tractor to the correct parts list and diagrams. For example, the manual’s electrical and chassis diagrams are labeled for TRACTOR MODEL NUMBER 917.273663, which helps you match the correct components and hardware.
