What engine does Craftsman riding mower use?
The Craftsman lawn tractor model 917272059 is equipped with a 16 HP low-emission engine (as listed in the owner’s manual). For the exact engine manufacturer and model family used on your tractor, match the engine ID label on the engine to the specifications in the 917272059 owner's manual.
How to identify the exact engine on model 917272059
Use these quick checks to confirm the engine make and model so you get the right tune-up and repair parts:
- Locate the engine ID label (typically on the blower housing, valve cover area, or near the starter)
- Write down the engine model, type, and code (or spec number)
- Compare those numbers to the engine section/specifications in the 917272059 owner's manual
- Use the engine ID when selecting parts like spark plugs, air filters, and fuel filters
- If the label is dirty, wipe it gently; avoid spraying water directly into electrical components
What we know from the manual (model-specific)
The owner’s manual for Craftsman 917272059 describes the tractor as:
| Item | Model-specific detail |
|---|---|
| Tractor model | 917272059 |
| Engine power rating | 16 HP |
| Mower deck size | 42 in |
| Starting system | Electric start |
| Transmission | 6-speed transaxle |
Why it matters
Engine identification prevents wrong-part returns and saves time during maintenance. The same tractor platform can be paired with different engine variants over production runs, and the engine ID is what determines the correct ignition, fuel, and air-intake parts.

What year was Craftsman 917272059 made?
The Craftsman lawn tractor model 917272059 is typically from the mid-2000s era (about 2004 to 2006). We confirm this is the correct model family by matching the model number in the parts list and diagrams in the 917272059 owner's manual.
How we date this model
Craftsman 917-series tractors are commonly dated by the model’s parts breakdown, engine family, and decal/feature set shown in the manual.
Key indicators we use:
- The manual explicitly lists TRACTOR MODEL NUMBER 917.272059 in multiple assemblies (chassis, steering, engine).
- The engine listing shows a Kohler CV460 configuration in the engine breakdown.
- The deck and hood decal set shown aligns with LT-style tractors sold in that timeframe.
Quick reference
| Item | What we see for model 917272059 | What it suggests |
|---|---|---|
| Manual model match | 917.272059 appears in diagrams | Confirms the exact model |
| Engine family | Kohler CV460 listed | Common on mid-2000s LT tractors |
| Deck labeling | 42-inch deck decals referenced | Typical LT2000-style setup |
Why it matters
Knowing the approximate build era helps you choose compatible maintenance parts (blades, belts, mandrel components) and follow the correct service procedures for your exact chassis and deck configuration.
Helpful next steps
- Use the 917272059 owner's manual parts diagrams to match your exact deck and chassis layout
- If you are servicing the cutting system, confirm blade style and deck setup before ordering

How much does it cost to replace a riding lawn mower engine?
For a Craftsman lawn tractor model 917272059, replacing the engine typically costs about $260 to $1,800 installed, depending on the engine type, whether you choose OEM or aftermarket, and local labor rates. Most shops bill around 5 to 8 labor hours for a riding mower engine swap.
What drives the total cost
- Engine price: short block vs complete engine, horsepower, and crankshaft specs
- Labor time: removal, transfer of parts, and setup (throttle/choke, wiring, fuel)
- Extra parts: belts, pulleys, filters, fuel line, clamps, battery cables
- Condition issues: rusted fasteners, damaged wiring, worn PTO components
- Shop rates: regional hourly labor differences
Typical cost breakdown (installed)
| Cost item | Typical range | Notes |
|---|---|---|
| Engine (part only) | $200 to $1,400 | Biggest variable; match crankshaft size and PTO setup |
| Labor | $200 to $700 | Often 5 to 8 hours total |
| Misc. parts and fluids | $20 to $200 | Oil, filter, fuel filter, hardware |
| Estimated total | $260 to $1,800 | Common real-world range |
Before you replace the engine
Many “needs an engine” symptoms are caused by starting or fuel issues. We recommend checking these first:
- Battery charge and cable connections
- Starter solenoid and starter operation
- Fuel quality, fuel filter, and fuel flow
- Spark plug condition and ignition spark
- Safety interlock switches (seat switch, brake/clutch switch, PTO switch)
If the engine clicks but will not crank, use riding lawn mower engine clicks but doesnt turn over video. If it cranks but will not start, use riding lawn mower engine spins but wont start video.
Why it matters
An engine replacement can cost close to the value of an older 42-inch riding mower. Pricing the job up front helps you decide whether to repair, repower, or put that money into blades, belts, and deck service that restores cut quality.
For model-specific maintenance intervals and operating checks (including safety interlock behavior), use the 917272059 owner’s manual.

Is it worth replacing a lawn mower engine?
Yes; replacing the engine on your Craftsman lawn tractor model 917272059 is worth it when the deck, steering, and transaxle are still solid and the total swap cost stays well below the cost of a comparable new riding mower. Use the 917272059 owner’s manual for safety interlock checks and service intervals.
Quick decision checklist
- Deck is structurally sound (not rusted through, no major cracks)
- Transaxle drives smoothly (no slipping, grinding, or loss of drive)
- Steering and frame are tight (no excessive play or damage)
- You can handle the labor or have a shop do the swap
- You want to keep your current deck and attachments
Cost rule of thumb
If the engine swap total (engine, fluids, hardware, labor) is more than about 50% of a comparable new tractor, replacing the tractor is the better value. If it is well under that mark, an engine swap is a strong investment.
| Condition of the tractor | Best choice | Why it matters |
|---|---|---|
| Chassis, deck, and drive are in good shape | Replace engine | Restores power and starting without replacing the whole machine |
| Deck and drive system both need major work | Replace tractor | Repair costs stack up and reliability drops |
| You need minimal downtime | Replace tractor | Fewer surprises than a major rebuild |
What to inspect before you buy an engine
- Blade and mandrel condition: the manual links vibration and poor cut to worn or bent parts; a deck issue can feel like an engine problem
- Deck belt condition: glazing, cracking, or slipping under load
- Cooling and maintenance history: clogged screens and cooling fins shorten engine life
- Safety interlocks: seat and clutch/brake interlocks must operate correctly before you run the tractor
If vibration or cut quality is the main complaint, replacing deck wear parts first can solve it without an engine swap; for example, a damaged blade or loose hardware can cause heavy vibration.
Helpful deck parts to consider during inspection:
Why it matters
An engine swap restores power, but it will not fix a worn deck, bent mandrel, or slipping belt. Checking the deck, belts, and safety systems first prevents spending engine money on a tractor that still will not cut or drive correctly.
