Do Craftsman mowers use Briggs and Stratton engines?
Some Craftsman mowers use Briggs and Stratton engines, but it depends on the specific mower model and production year. For the Craftsman lawn tractor model 917287120, the engine brand is identified in the specifications section of the 917287120 owner's manual, which is the best way to confirm what your tractor was built with.
How to confirm the engine brand on your Craftsman 917287120
We recommend checking the tractor itself and matching it to the manual specs.
- Look for the engine ID label on the engine shroud or valve cover (often lists brand and model).
- Compare the engine model and type to the “Product Specifications” section in the manual.
- Use the tractor model number 917287120 (not just “917.28712”) when cross-referencing parts.
- If you are ordering tune-up parts, match by engine model, not only by tractor model.
- If the engine has been replaced, the current engine brand may differ from the original.
Common Craftsman engine brands (what you may see)
Craftsman has used multiple engine suppliers across different mower lines.
| Craftsman mower type | Common engine brands you may find | What to verify first |
|---|---|---|
| Riding lawn tractor | Briggs and Stratton, Kohler, Tecumseh (older units) | Engine model label |
| Push mower | Briggs and Stratton, Honda (varies by series) | Product tag and engine label |
Why it matters
The engine brand determines the correct maintenance parts and service procedures (oil type, spark plug, air filter, fuel filter, and carburetor parts). Using the engine model ID prevents ordering the wrong parts even when the deck size and tractor model match.

What Craftsman lawnmower do I have?
If you have a Craftsman riding mower or lawn tractor, the fastest way to identify exactly what you own is to match the model number on the product identification label to your paperwork and parts diagrams. For this page, the model is Craftsman 917287120; confirm your label shows 917.28712 or 917287120. See the 917287120 owner's manual for label location details and model identification.
Where to find the model number on a Craftsman lawn tractor
On Craftsman tractors like 917287120, the product identification label is commonly located under the seat area. Check these spots first:
- Underside of the seat or seat pan (lift the seat)

- Near the rear fender or chassis rail close to the seat
- On the mower deck shell (less common for the primary model label)
What to write down (so you get the right parts)
Record the information exactly as printed; one character off can change the parts list.
- Model number (example: 917.28712)
- Product number (if listed)
- Engine model and type (often on the engine itself)
- Serial number (helpful for production changes)
Model number formats you might see
Craftsman tractor labels often show the model with or without punctuation.
| You see on the label | How it’s used for parts lookup |
|---|---|
| 917.28712 | Same model as 917287120 |
| 917287120 | Same model as 917.28712 |
| A different 917.xxxxx | Different model; parts can vary |
Why it matters
The model number determines the correct deck size, blade style, belts, and electrical parts. For example, a 42-inch deck setup can use different blade types and drive components depending on the exact model and production run.

What size belt does a 42 inch Craftsman deck take?
For the Craftsman lawn tractor model 917287120 with a 42-inch mower deck, the deck belt is typically 1/2-inch wide and usually falls around 95 to 101 inches long depending on the exact deck and pulley setup. We recommend confirming the belt routing and spec in the 917287120 owner's manual.
Quick way to identify the correct belt size
- Check the old belt for printed width and length (often stamped on the outer surface).
- Compare the belt path to the routing diagram in the manual.
- Measure the belt width with a ruler or caliper; most 42-inch decks use a 1/2-inch belt.
- If the belt is missing, measure the belt path with a flexible tape (around all pulleys and idlers).
- Inspect idler pulleys and mandrel pulleys for wear; worn pulleys can throw off fit and cause slipping.
Belt length guidance for this model
The parts list for this model includes a belt listed as 1/2 x 101-1/6 inches, which is a common size range for a 42-inch deck/drive application on tractors like this.
| What you’re checking | Typical value for 42-inch decks | What to do next |
|---|---|---|
| Belt width | 1/2 in | Match width first; wrong width slips or jumps |
| Belt length | ~95 to ~101 in | Use routing diagram and pulley count to confirm |
| Belt condition | No cracks, glazing, or fraying | Replace if worn to prevent poor cut and belt breakage |
Parts that commonly affect belt fit and performance
If the belt keeps coming off or squeals, these deck components are often involved:
- Husqvarna lawn tractor belt, 1/2 x 101-1/6-in 592855001 (correct width range for this tractor)
- Mandrel pulley 532195945 (worn grooves can shred belts)
- Lawn tractor mandrel housing 587819701 (bearing drag can overheat belts)
Why it matters
A belt that is even slightly off in width or length can cause blade speed loss, uneven cutting, premature belt wear, or repeated belt derailment. Matching the belt to the correct routing and pulley setup is the fastest way to get reliable mowing performance.
