Craftsman 917287120 lawn tractor Parts

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.

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.

Craftsman has used multiple engine suppliers across different mower lines.

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.

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.

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)
• Left side of the frame under the seat area
• Near the rear fender or chassis rail close to the seat
• On the mower deck shell (less common for the primary model label)

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)

Craftsman tractor labels often show the model with or without punctuation.

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.

The model number for this Craftsman front-engine lawn tractor is 917.28712 (often written without the dot as 917287120). You can confirm it on the model tag and in the 917287120 owner's manual.

We recommend checking these common locations on Craftsman riding mowers:

• Under the seat on the fender pan or seat bracket area
• On the frame near the engine compartment
• Near the rear hitch plate or drawbar area
• Inside the hood area on the chassis rail

Manufacturers and parts sites format the same model number a few different ways.

Using the exact model number helps us match the correct diagrams and parts for your mower deck, drive system, and electrical components. For example, the correct starter circuit parts can vary by model; a common replacement on this model is the lawn tractor starter solenoid 582042802.

Before ordering parts, we match these details:

• Model number (917.28712 or 917287120)
• Product type (front-engine lawn tractor)
• Deck size (this model is commonly listed with a 42-inch mower deck)
• Engine and transmission type listed in the manual

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.

• 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.

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.

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)

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.
