What model number is a Craftsman 6.75 lawn mower?
A “Craftsman 6.75” is a power rating, not a unique model number; the exact model depends on the mower’s product label. For the Craftsman lawn tractor on this page, the model number is 917.275682 (shown in the 917275682 owner's manual).
Check the product identification label on the mower; it lists the model number and usually a serial number.
- Look on the rear of the deck near the discharge chute
- Check under the seat (riding models) or on the frame rail
- Look near the engine mounting area or behind the front wheels
- Write down the full model number exactly as shown (numbers and dots)
- Use the model number to match the correct blades, belts, and engine parts
“6.75” typically refers to an engine power class used across many Craftsman walk-behind mowers. Multiple different models can share the same 6.75 rating, so parts lookup must be done by model number.
| What you have | What it tells you | What you still need |
|---|---|---|
| “6.75” on the engine cover | General engine power class | The mower model number from the ID label |
| Model 917.275682 | Exact Craftsman model on this page | Use it to select the right deck, blades, and belts |
Using the correct model number prevents ordering the wrong cutting blade, drive belt, or PTO switch. Even small deck and frame changes between similar Craftsman mowers can change part fit.

Is it worth replacing a lawn mower engine?
Yes, it’s worth replacing the engine on your Craftsman lawn tractor model 917275682 when the tractor’s deck, steering, and transmission are still solid and you want more years of service. If the total engine job approaches about half the cost of a comparable replacement tractor, putting that money toward a new unit is usually the better value.
- The mower deck is not rusted through and still cuts evenly after leveling
- The transmission drives normally (no slipping, no loss of motion)
- The frame and steering are tight (no excessive play)
- You can do the work yourself or have a shop you trust
- You can source the correct engine and any required pulleys, wiring, and mounting hardware
Engine replacement is more than “swap and go”; it often includes belt routing checks, PTO engagement checks, and safety switch verification.
| Option | Upfront cost | Time/effort | Best when |
|---|---|---|---|
| Replace engine | Medium to high | High | Tractor is otherwise in great shape |
| Repair existing engine | Low to medium | Medium | Issue is fuel, ignition, carburetion, or compression-related |
| Replace tractor | High | Low | Multiple major systems are worn out |
Use the maintenance and safety guidance in the 917275682 owner’s manual to evaluate overall condition. Focus on these areas first:
- Blade and deck condition: blades must be sharp and not bent; blade bolts must be tightened properly
- Mandrel and deck hardware: listen for bearing noise and check for wobble at the blade spindles
- Belts: worn belts can mimic power loss; inspect the ground drive belt and blade drive belt
- Safety systems: the reverse operation system (ROS) and interlocks must function correctly
- General service condition: debris buildup, loose fasteners, and fuel or oil leaks add risk and cost
A new engine can restore reliability, but it will not fix a worn deck, failing mandrel bearings, or slipping belts. Confirming the deck and drive systems are healthy prevents spending engine money on a tractor that still won’t perform.

How much does it cost to replace a riding lawn mower engine?
For a Craftsman riding lawn tractor like model 917275682, engine replacement typically runs about $800 to $2,500 total (engine plus labor). The biggest cost drivers are the exact engine type, whether any pulleys or wiring need updates, and shop labor time; confirm specs in the 917275682 owner's manual.
- Engine type and horsepower: exact replacement engines cost more than “universal” options.
- Labor time: riding mower engine swaps commonly take around 4 to 8 hours depending on rusted fasteners and access.
- Extra parts found during teardown: worn belts, damaged pulleys, or electrical issues add cost.
- Delivery and core charges: freight can be significant for engines.
- DIY vs. shop install: DIY saves labor but requires safe lifting and correct belt routing.
Even if you are replacing the engine, we often see these wear items addressed during the job:
| Item | Why it is replaced | Example for this model |
|---|---|---|
| Ground drive belt | Cracking, glazing, slipping | Lawn tractor ground drive belt, 1/2 x 82-in 532140294 |
| Blade drive belt | Deck engagement issues, belt wear | Craftsman lawn tractor blade drive belt, 5/8 x 97-2/5-in 532174883 |
| PTO switch | Intermittent deck engagement | Switch.pto 582107601 |
| Cost piece | Typical range |
|---|---|
| Engine (part only) | $500 to $1,800 |
| Labor | $300 to $900 |
| “While you’re in there” parts | $0 to $250 |
A replacement engine can make sense when the tractor’s deck, transmission, and steering are still in good shape. If multiple major systems are worn, putting that money toward a different mower can be the better value.

What brand engine does Craftsman use?
Craftsman uses engines from multiple manufacturers across its riding mower and lawn tractor lineup. For Craftsman lawn tractor model 917275682, the engine is a Briggs & Stratton (24 HP class) engine; confirm the exact engine model and type on the engine ID label and in the 917275682 owner's manual.
Depending on the tractor series and production year, Craftsman tractors are commonly equipped with:
- Briggs & Stratton engines (very common on many Craftsman riders)
- Kohler engines (common on mid to higher horsepower models)
- Kawasaki engines (used on some higher-end configurations)
- Other OEM-supplied engines on certain model years
Use these checks on your Craftsman 917275682 to match parts and service info correctly:
- Find the engine ID label on the blower housing, valve cover, or near the starter
- Write down the engine model, type, and code numbers from that label
- Cross-check those numbers in the 917275682 owner's manual for maintenance specs
- Use the engine numbers (not only the tractor model) when buying tune-up items like spark plugs, air filters, and oil filters
| Where you check | What you’ll find | Best use |
|---|---|---|
| Engine ID label/plate | Manufacturer plus engine model/type/code | Correct engine parts and service procedures |
| Owner’s manual | Maintenance intervals, oil type/capacity, adjustments | Proper upkeep and troubleshooting |
| Tractor parts diagrams | Deck, drive, steering, and electrical parts | Correct tractor-mounted parts selection |
Engine brand and engine model numbers control the exact maintenance parts and settings. Using only the tractor model can lead to the wrong spark plug, air filter, or oil filter, even when the tractor is the correct model.
