Your Craftsman riding mower model number is on the tractor’s ID label (not on the engine). For the Craftsman model 917273811, the model number is used to match the correct parts list, decals, and deck components; confirm it on the label and in the 917273811 owner's manual.

On most Craftsman front-engine lawn tractors, the model/serial label is typically found in one of these spots:

• Under the seat on the seat pan or fender area
• On the rear fender deck near the seat
• On the frame rail near the engine compartment
• Under the hood area on the chassis (near the steering column)
• Near the footrest area on the frame

For Craftsman tractors, the model number is usually a 9-digit number (often shown with a dot in manuals).

The engine has its own model/type/code, but that is mainly for engine-specific parts. For everything else (mower deck, steering, chassis, wheels, electrical), use the tractor model number.

• Mower deck assembly and belt routing
• Blades and mandrel assemblies
• Steering gears and front axle parts
• Wheels and tires
• Ignition key and dash components

Using the correct model number prevents ordering the wrong deck parts or blades for a 42-inch setup. For example, once you confirm you have model 917273811, you can confidently match common wear items like the lawn tractor 42-in deck high-lift blade 532138971 to the correct deck configuration.

For the Craftsman lawn tractor model 917273811, use a high-quality detergent 4-cycle engine oil that meets API service classification SG-SL, and choose the SAE viscosity based on your expected outdoor temperature (per the oil viscosity chart in the owner's manual).

The manual specifies an API rating (SG-SL) and directs you to select viscosity by temperature. In practice, these are the most common choices for riding mower engines:

• SAE 10W-30: best all-around choice for many climates
• SAE 5W-30: best for colder starts and early-season mowing
• SAE 30: common for consistently warm weather

If you already have 5W-30 4-cycle engine oil, it’s a solid choice for cooler weather operation and easier starting.

Keeping the oil at the correct level matters as much as the oil type.

• Check oil with the tractor on level ground
• Wipe the dipstick, reinstall and tighten, then recheck the level
• Fill only to the FULL mark (do not overfill)
• Check oil before starting and after each 8 hours of operation
• Change oil every 50 hours of operation or at least once a year

Running low on oil or using the wrong viscosity increases heat and wear. On a front-engine tractor like the Craftsman 917273811, correct oil level and timely changes help protect the engine and keep starting and mowing performance consistent.

For the Craftsman front-engine lawn tractor with a 42-inch mower deck on this page, the model number is 917.273811. You can confirm it on the product ID label and in the 917273811 owner's manual.

Use these quick checks to make sure you are matching parts and diagrams to the right Craftsman tractor:

• Check the product ID label under the seat, on the frame, or near the rear fender area
• Match the model format; Craftsman tractor models commonly start with 917.
• Verify the deck size; this model uses a 42-inch mower deck
• Cross-check the model number in the manual parts lists and diagrams
• Use the model number (not just “Craftsman 42”) when ordering blades, belts, and mandrel parts

On Craftsman riding mowers, “42” typically refers to the cutting width of the mower deck, not the tractor itself. For model 917.273811, the manual’s mower deck section lists a 42-inch deck assembly and compatible blades.

If you are shopping for deck parts, the model number matters because blade style and mounting can vary.

• For mulching setups, use the husqvarna lawn tractor mulching blade, 21-in 532134149
• For bagging or side discharge, use the lawn tractor 42-in deck high-lift blade 532138971
• For deck drive issues (slipping, squealing, poor blade speed), check the condition and routing of the ground drive and deck belts

Using the correct model number (917.273811) prevents wrong-part returns and helps you get the right diagrams for deck, electrical, steering, and chassis components.
