Is it worth replacing a lawn mower engine?
Yes; replacing the engine on your Craftsman lawn tractor model 917272460 is worth it when the deck, chassis, steering, and drive system are still in good condition and you want several more seasons of service. If multiple major systems are worn out, replacement makes more sense.
- Deck is not rusted through and the mandrel area is solid
- Tractor drives normally (no chronic slipping or loss of drive)
- You can keep up with routine maintenance (cooling, fuel, ignition)
- Engine-swap total cost stays well below a comparable replacement tractor
- Wear parts are still available for ongoing upkeep
| Condition on the tractor | What it usually means | Best move |
|---|---|---|
| Deck and chassis are solid; engine is the main failure | Good candidate for an engine swap | Replace engine |
| Deck is heavily corroded or damaged; several systems worn | Repairs stack up quickly | Replace tractor |
| Blades do not rotate due to deck/mandrel problems | Cutting system needs repair first | Fix deck first |
| Loss of drive caused by a worn belt | Often a lower-cost repair | Repair drive system |
The 917272460 manual calls out maintenance items that prevent engine damage and no-start complaints.
- Keep the grass screen and cooling fins clean to prevent overheating
- Replace the in-line fuel filter once each season
- Replace spark plug(s) at the beginning of each mowing season or every 100 hours
- Never make adjustments or repairs with the engine running
For model-specific procedures and safety steps, use the 917272460 owner's manual.
- Drive slipping or no movement: lawn tractor ground drive belt, 1/2 x 82-in 532140294
- Clicking/no crank electrical issue: solenoid with brass plunger 532146154
- Poor cut or vibration: inspect blades and mandrel components
An engine swap pays off only when the cutting deck and drive system are dependable; fixing cooling, fuel, or belt problems first prevents repeat failures.

What engine does Craftsman riding mower use?
Craftsman lawn tractor model 917272460 is a 42-inch, electric-start riding tractor with a low-emission gasoline engine. The exact engine brand and model are identified on the engine ID label and in the Product Specifications section of the owner's manual.
Use the engine’s identification tag, then match it to the tractor documentation.
- Find the engine ID label on the blower housing, valve cover, or near the starter
- Write down the engine model, type/spec, and code (these are the key service identifiers)
- Match those numbers to the engine information listed in the owner's manual
- Use the engine ID when buying tune-up items (spark plug, air filter, fuel filter)
- If the label is dirty, wipe it clean; if it is missing, look for stamped numbers on the shroud
These are the tractor-level specs we use to guide correct maintenance and troubleshooting.
| Item | What it means for you |
|---|---|
| 42-inch mower deck | Blade and deck parts must match a 42-inch deck setup |
| Electric start | Starting system includes battery, starter, wiring, and solenoid |
| Low-emission engine | Follow the manual’s starting and warm-up procedure |
Craftsman used multiple engine suppliers across similar-looking tractors; the engine ID is what prevents ordering the wrong carburetor, ignition parts, or tune-up kit.
If the engine clicks but will not crank, the starting circuit is a common place to check first.
- Solenoid with brass plunger 532146154 (starter solenoid)
- Battery cables and connections (clean and tighten)
- Safety interlock switches (seat, brake, PTO)
- Ignition key and switch circuit
For ordering, use the parts list for model 917272460 on this page, or search by model number on Sears PartsDirect.

What model number is a Craftsman 6.75 lawn mower?
“6.75” is an engine power class label, not a single Craftsman model number. For the Craftsman front-engine lawn tractor covered by this page, the model number is 917.272460 (shown on the cover of the owner's manual).
We use the equipment model number from the product ID tag, not the engine shroud label.
- Check under the seat on riding mowers and lawn tractors
- Look on the frame near the rear wheels or footrest area
- Check near the steering column or dash support
- Write down the full model number and any serial number
- Use the full model number when ordering blades, belts, ignition parts, and deck hardware
| Marking you see | What it identifies | Best use |
|---|---|---|
| 6.75 (on engine cover) | Engine power class | General reference only |
| 917.272460 | Craftsman equipment model number | Correct identifier for most parts |
| Engine model/type numbers | Engine manufacturer identifiers | Engine-only parts and tune-up items |
Deck size, transmission, and chassis design change which blade, belt, or ignition components fit. Using the equipment model number prevents ordering a part that looks similar but mounts differently.
This model uses a 42-inch mower deck; common deck and starting items include:
- Blade 42" 532138971
- Lawn tractor ground drive belt, 1/2 x 82-in 532140294
- Molded ignition key 532140403
If you are trying to identify a different Craftsman mower that only says “6.75,” use the ID tag model number first; then you can search parts by that model on Sears PartsDirect.

What year was Craftsman 917272460 made?
Craftsman model 917272460 was built across multiple production runs (not a single model-year), so the exact year is identified by the serial number/date code on the tractor’s ID plate. We use the ID plate information to match the correct parts and specifications in the owner's manual.
Check these common locations for the product identification label:
- Under the seat (lift the seat pan and look on the fender pan area)
- On the frame near the rear wheels
- Under the hood near the dash tower (less common)
- Near the transmission area on the frame rail
Write down:
- Model number: 917272460
- Serial number (full string)
- Any date code (letters and numbers)
Once you have the serial/date code, you can use it to confirm the correct configuration for maintenance items like blades, belts, and electrical parts.
Common parts that vary by configuration include:
- Mower deck blades (standard vs. mulching vs. high-lift)
- Ground drive belt length and routing
- Electrical items such as the ignition key and starter solenoid
| System | Example part | What it affects |
|---|---|---|
| Mower deck | Blade 42" 532138971 | Cut quality and discharge |
| Mower deck | Husqvarna lawn tractor mulching blade, 21-in 532134149 | Mulching performance |
| Electrical | Molded ignition key 532140403 | Starting and key fit |
| Starting | Solenoid with brass plunger 532146154 | Cranking power to starter |
The build year and serial/date code help ensure we match the correct deck setup and wiring configuration for your Craftsman front-engine lawn tractor, which prevents ordering the wrong blade style, belt, or electrical component.
If you need to order parts beyond what’s listed here, we recommend searching by model number on Sears PartsDirect.
