What model number is a Craftsman 6.75 lawn mower?
A “Craftsman 6.75” label by itself is not a single model number; it usually refers to the engine’s horsepower class, not the mower’s model. For the Craftsman tractor model 917276330, the correct model number is printed on the ID tag and shown in the 917276330 owner's manual.
Where to find the model number on a Craftsman mower
On most Craftsman walk-behind mowers and riding mowers, the model number is on an ID label, not on the engine cover.
- Walk-behind mower: rear deck area, near the wheels, or on the back flap/handle bracket
- Riding mower/tractor: under the seat, on the frame near the rear fender, or near the engine compartment
- Sometimes listed as “Model No.” and may include dots (example: 917.276330)
What “6.75” usually means (and why it matters)
“6.75” is commonly used to describe an engine power class. Different mower models can use similar engines, so using “6.75” alone can lead to ordering the wrong belt, blade, or ignition parts.
Why it matters
- Parts look similar but mount differently (blade adapters, pulleys, deck hardware)
- Belts vary by length and width
- Electrical parts can differ by connector style and safety interlock design
Quick checklist to identify the right model
Use this checklist before ordering parts:
- Write down the full model number from the mower’s ID tag (often starts with 917 for Craftsman)
- If present, record the product number and serial number
- For tractors, also note deck size (example shown for 917276330 is a 54-inch deck)
Common Craftsman numbering examples
| What you see | What it is | What to use for parts |
|---|---|---|
| 6.75 | Engine power class | Not enough by itself |
| 917.XXXXXX | Craftsman model format | Use the full 917 model |
| Engine model (Briggs & Stratton) | Engine ID | Use for engine-only parts |
If you are trying to identify a walk-behind Craftsman 6.75 mower (not a tractor), match the full model number from the mower’s ID tag to the parts list for that exact model.

Common engine-related symptoms and what they usually point to
The manual’s troubleshooting chart highlights several common causes of power loss and poor running. Here is a practical way to group them:
| Symptom | Most common causes | What to check first |
|---|---|---|
| Loss of power | Dirty air filter, stale fuel, low/dirty oil | Air filter condition, fresh fuel, oil level |
| Hard starting (cold) | Choke not used correctly, weak battery | Choke operation, battery charge |
| Rough running | Spark plug, fuel delivery, clogged muffler/screen | Spark plug, fuel filter, air screen |
Parts that often relate to “engine won’t start” complaints
If the engine type is correct but the tractor will not crank or start, these model-compatible electrical parts are commonly involved:
- Solenoid with brass plunger 532146154 (starter circuit switching)
- Lawn tractor ignition switch 532193350 (key switch power routing)
- Molded ignition key 532140403 (worn key can cause intermittent contact)
Why it matters
On riding mowers, the tractor model number (917276330) identifies the chassis and deck, but the engine ID determines the correct engine-specific maintenance parts and settings. Matching both prevents wrong parts and repeat starting or performance problems.
