What model number is a Craftsman 6.75 lawn mower?
A “Craftsman 6.75” is a walk-behind mower description, not a single model number. On our Craftsman equipment, the exact model number is found on the product ID tag; for riding tractors like Craftsman model 917.276760, the operator manual also lists it clearly in the front pages of the 917.276760 owner's manual.
How to find the correct model number on a 6.75 mower
Look for the model number on the mower’s ID label (not the engine cover). Common label locations include:
- Rear of the deck near the discharge chute
- Under the seat area on self-propelled models (if equipped)
- On the handle bracket or rear frame
- Near the engine mounting area on the deck
- On a sticker or metal tag with “Model” and “Serial”
What to write down (so you get the right parts)
For parts lookup and diagrams, we recommend capturing these details exactly as printed:
- Full model number (all digits and punctuation)
- Serial number (helps confirm production run)
- Product type (walk-behind mower vs. riding mower/tractor)
- Deck size (for example, 21-inch walk-behind decks are common)
- Engine brand and model (helpful for tune-up parts)
Quick comparison: “6.75” vs. the model number
| Item on the mower | What it tells you | What we use for parts |
|---|---|---|
| 6.75 (HP rating) | General power class | Not enough by itself |
| Model number | Exact mower identity | Primary lookup key |
| Serial number | Build/run details | Confirms correct match |
Why it matters
Many Craftsman mowers share similar 6.75 HP labeling but use different blades, belts, air filters, and carburetor parts. Using the exact model number prevents ordering the wrong part and avoids fitment issues.

What are the parts of a lawn mower engine?
On the Craftsman 917276760 front-engine lawn tractor, the engine system is made up of fuel, air, ignition, and mechanical components that work together to create combustion and turn the crankshaft; the tractor also adds safety and control linkages that affect starting and operation (see the 917276760 owner's manual).
Core engine parts (what they do)
- Fuel system: fuel tank, fuel lines, fuel filter (if equipped), carburetor
- Air intake: air filter, intake housing, engine air screen/fins (cooling airflow)
- Ignition: ignition switch, ignition coil, spark plug, spark plug wire
- Mechanical: cylinder, piston, connecting rod, crankshaft, crankcase
- Starting/charging: starter motor, starter solenoid, battery, charging circuit
- Exhaust: muffler
Tractor-specific controls that affect the engine
Your riding tractor adds controls and safety circuits that can prevent starting or shut the engine down if conditions are unsafe.
- Clutch/brake pedal: used for declutching, braking, and starting the engine
- Throttle/choke control: used for starting and controlling engine speed
- Operator-presence and reverse operation system (ROS): safety interlocks tied to seat/brake/attachment operation
Quick reference table
| System | Common parts | Typical symptom when faulty |
|---|---|---|
| Fuel | tank, carburetor | cranks but will not start, surging |
| Air | air filter, air screen/fins | loss of power, overheating |
| Ignition | switch, coil, spark plug | no spark, intermittent start |
| Starting | battery, solenoid | clicking, no crank |
Why it matters
Knowing which system you are dealing with speeds up troubleshooting. For example, a “click but no crank” points you toward the battery and starting circuit, while rough running often points to air/fuel delivery or ignition.
Helpful DIY guidance
For starting-circuit symptoms, use riding lawn mower engine clicks but doesnt turn over video.

Is it worth repairing a lawn mower engine?
Yes, it’s usually worth repairing the engine on your Craftsman lawn tractor model 917276760 when the problem is a maintenance item or a bolt-on part (fuel, ignition, starting, belts). If the repair requires major internal engine work, replacement is typically the better value.
Quick decision guide (cost vs. value)
Use these ranges to decide quickly:
- Under $100: almost always worth it (spark plug, air filter, fuel system cleaning)
- $100 to $300: worth it if the tractor is otherwise solid (deck, transmission, steering)
- Over $300: usually replace the engine or the tractor unless you do the labor yourself
- Any cost: fix first if it’s a safety or reliability issue (brakes, wiring, fuel leaks)
| Repair type | Common examples | Usually worth it? |
|---|---|---|
| Maintenance / tune-up | Spark plug, air filter, fresh fuel | Yes |
| Starting / electrical | Battery cables, solenoid, key switch | Often |
| Fuel / carburetion | Cleaning carburetor, replacing fuel filter | Often |
| Major engine work | Valves, compression issues, rebuild | Usually no |
What we recommend checking first (fast, high-impact)
The manual’s maintenance schedule supports starting with basics that improve engine life and performance.
- Check engine oil level before each use
- Replace the spark plug at least yearly
- Clean or replace the air filter at least yearly
- Inspect wiring and connections if starting is inconsistent
- Clean debris buildup around hot engine/exhaust areas before testing or storing
For model-specific maintenance intervals and procedures, use the 917276760 owner’s manual.
When a “repair” is really a mower-deck issue
Many “engine problems” are actually load problems from the cutting system. If the tractor bogs down, vibrates, or cuts poorly, inspect the deck for buildup and worn rotating parts.
- Clear packed grass under the deck
- Check for bent or loose blades
- Inspect mandrels and pulleys for binding
If you’re chasing vibration or uneven cutting, replacing a worn blade can be a smart first step; for example, the lawn tractor 42-in deck high-lift blade 532138971 is a common wear item on this model’s deck setup.
Why it matters
A small, targeted repair keeps your 917276760 reliable and safe. The manual emphasizes routine checks (oil, brakes, tire pressure) and keeping debris off hot engine parts, which prevents bigger failures and reduces downtime.

Who makes the 547cc IntelliPOWER engine?
“547cc IntelliPOWER” is an engine marketing label used on some newer riding mowers; it is not the engine description used for Craftsman model 917276760 in our operator literature. To identify who made your engine, match the manufacturer using the engine’s model and code from the engine ID label, then cross-reference it in the 917276760 owner's manual.
How to identify the engine maker on Craftsman 917276760
The tractor model number identifies the mower platform; the engine maker is identified from the engine tag.
- Park on level ground, set the parking brake, and remove the key
- Let the engine cool completely before touching shrouds or muffler areas
- Lift the hood and find the engine ID label (commonly on the blower housing or valve cover area)
- Write down the full engine model, type/spec, and code
- Use that information when ordering tune-up parts and when looking up engine service data
What “IntelliPOWER” means (and why it can be confusing)
“IntelliPOWER” is typically used to describe an engine system designed to maintain power under load. It is not a standardized service identifier like an engine model/type code, so it does not reliably tell you the manufacturer by itself.
Quick check table
| Item you have | Where to find it | What it tells you |
|---|---|---|
| Engine model/type/code | Label or stamped tag on the engine | Engine manufacturer and exact engine family |
| Tractor model 917276760 | Tractor ID tag, manual cover | Tractor platform, controls, and maintenance schedule |
| “547cc IntelliPOWER” wording | Product listing or decal | Feature branding, not a parts lookup key |
Why it matters
Using the engine model/type/code prevents ordering the wrong air filter, spark plug, or fuel system parts and ensures you follow the correct adjustment procedures for your specific engine.
