Craftsman 917273820 tractor dyt4000 Parts

Craftsman uses engines from multiple manufacturers across different tractor and mower models. For the Craftsman lawn tractor model 917273820, the owner’s documentation identifies it as a low-emission internal combustion engine, but it does not call out a single engine brand name in the excerpted pages; check the engine shroud label and the owner's manual for the exact engine identification details.

Across Craftsman riding mowers and lawn tractors, it’s common to find engines supplied by major small-engine makers. The exact brand depends on the specific model and production run.

• Briggs & Stratton (very common on many Craftsman models)
• Kohler (common on some higher-output configurations)
• Kawasaki (less common, but used on select models)
• Craftsman-branded labeling on the tractor does not always match the engine maker
• The engine model and type are usually printed on the engine itself (blower housing, valve cover area, or emissions label)

Use the tractor’s engine labeling to confirm the manufacturer and engine family.

• Turn the engine off and let it cool completely
• Lift the hood and look for an emissions label or stamped model/type code
• Check the recoil housing or blower shroud for a manufacturer badge
• Record the engine model and type numbers exactly as shown
• Match those numbers to the engine parts list and specifications in the owner's manual

Engine brand and engine model/type determine the correct tune-up parts and service specs (oil type, spark plug, air filter, belt routing references, and maintenance intervals). Using the engine’s exact ID prevents ordering the wrong parts for your Craftsman 917273820.

On your Craftsman tractor model 917273820, the engine identification is listed in the documentation as Briggs & Stratton engine model 31P777 with type 0296-E1. For the exact label location on the engine itself, use the diagrams and ID guidance in the owner's manual.

Most riding mower engines show the engine model and type on a label or stamping on the engine shroud or blower housing. Check these common spots:

• Top of the engine near the valve cover area
• Blower housing (the metal/plastic cover around the flywheel)
• Near the starter motor or solenoid area
• On the side of the engine shroud facing the seat
• On a stamped pad on the engine block (varies by engine family)

Engine IDs are usually a set of fields. Here is what each one is used for when matching parts like air filters, carburetor kits, or ignition components.

• Wipe off grass and oil film; use a flashlight to read faint stamping.
• Write the numbers down exactly, including dashes.
• If the label is missing, use the engine model and type shown in the owner's manual to narrow the match, then confirm by comparing your engine’s components (air cleaner style, carburetor linkage, muffler layout).

The tractor model number (917273820) helps match chassis and deck parts, but the engine model and type are what ensure you get the correct engine-specific parts and tune-up items.

The model number is 917.273820 (often written without the dot as 917273820) for this Craftsman front-engine lawn tractor (DYT4000 series). You can confirm it in the parts diagrams and identification sections of the owner's manual.

We recommend checking the tractor’s ID label and matching it to the manual and parts list.

• Look for the product identification label under the seat or near the rear fender area
• Match the label to the model shown in the electrical and chassis parts diagrams
• Record the full model number before ordering blades, belts, or electrical parts
• Use the model number to ensure the correct deck and steering components are selected

In documentation and parts lists, the same model can appear with or without punctuation.

The model number is the key to getting the right Craftsman riding mower and tractor parts. For example, the correct ignition and electrical components (like the molded key and solenoid) are tied to the exact model number, not just the tractor family name.

On your Craftsman riding tractor, the model number is typically on the product identification label under the seat or on the frame near the engine. For this unit, the model is 917273820; you can also confirm it in the 917273820 owner's manual.

• Near the rear fender area, inside the left or right side panel
• Under the hood on the chassis (less common)

Craftsman tractor model numbers are usually a 9-digit number (often shown with a dot in printed materials).

We use the model number to match the correct parts diagrams and replacement parts for your exact tractor configuration (mower deck, drive system, steering, and hardware). Even small model differences can change belts, blades, and deck components.

Before ordering, match both the model number and the part description. For example, if you are servicing the 42-inch deck, common wear items include blades such as the lawn tractor 42-in deck high-lift blade 532138971 or the husqvarna lawn tractor mulching blade, 21-in 532134149 (choose the blade style that matches how you mow).

Craftsman is a brand name, and Craftsman riding lawn tractors have been manufactured by different companies over the years depending on the model and production run. For your Craftsman lawn tractor model 917.273820, use the owner's manual and the parts diagrams to identify the correct OEM-style replacement parts and service procedures.
