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.
What this means for parts and service
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
Quick ID guide (tractor vs. engine)
| 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 |
Common signs you are dealing with an engine-specific issue
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.
Why it matters
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.
What drives the total cost
- 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
Typical cost breakdown (what you are paying for)
| 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 |
Parts that are commonly replaced at the same time
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)
Why it matters
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.
Where to confirm the correct engine and specs
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.

- Near the transaxle area on the frame (rear of tractor)
What the model number looks like
Craftsman tractor model numbers are commonly formatted with a dot:
