Craftsman 917270911 tractor Parts

Replacing the engine on a Craftsman riding lawn tractor like model 917270911 typically costs $260 to $1,800 installed, depending on the engine type, whether you reuse pulleys and wiring, and local labor rates. Most riding mower engine swaps take about 6 labor hours.

• Engine price (new vs. rebuilt, horsepower, shaft size and length)
• Labor time (shop rate and how much teardown is required)
• Extra parts often replaced during the swap (belts, pulleys, hardware)
• Fuel system cleanup if old fuel or debris contributed to the failure
• Electrical and safety interlock checks after installation

We recommend confirming the problem is truly a failed engine and not a starting or safety issue. The 917270911 uses an operator presence and interlock system; if it is not working correctly, the tractor may not start or may shut off unexpectedly.

• Verify the clutch/brake pedal is fully depressed
• Make sure the attachment clutch is disengaged
• Inspect battery cables and connections for corrosion or looseness
• Check for stale fuel, a dirty fuel filter, or a faulty spark plug
• Confirm the seat switch and parking brake shutoff behavior matches the manual

For the exact safety interlock behavior and service cautions for this model, use the 917270911 owner's manual.

An engine replacement is one of the highest-cost repairs on a riding mower. A quick diagnosis first can prevent spending hundreds on an engine when the real issue is a battery, wiring, fuel delivery, or an interlock switch.

For Craftsman lawn tractor model 917270911, the owner’s manual identifies it as a 19.5 HP electric-start tractor with a 42-inch mower deck and a 6-speed transaxle. For engine brand and model details, use the engine identification section in the 917270911 owner's manual.

We recommend confirming the engine by reading the engine data label (not the tractor frame tag). On most Craftsman front-engine tractors, the label is on the engine shroud or near the valve cover.

• Turn the engine off and let it cool completely
• Lift the hood and locate the engine data label
• Write down the engine model, type, and code (or spec number)
• Match those numbers when ordering tune-up parts (spark plug, air filter, fuel filter)
• If the label is missing, use the tractor’s parts diagrams and decals list in the manual to narrow down the engine family

The manual gives you tractor-level specs that help ensure you are looking at the right platform when identifying the engine.

The engine make and model determine the correct maintenance parts and settings (spark plug type, oil viscosity, valve clearance, and tune-up intervals). Using the wrong engine spec can cause hard starting, poor mowing performance, or premature wear.

If you are servicing the cutting system while you are identifying the engine, these model-matched parts are common wear items:

• Husqvarna lawn tractor mulching blade, 21-in 532134149 (blade condition affects cut quality)
• V-belt 532138255 (worn belts can slip and reduce deck performance)
• Molded ignition key 532140403 (handy if your key is worn or missing)

Craftsman model 917270911 was produced in the mid-2000s, most commonly around 2004 to 2006. For the most accurate date range for your exact tractor, we recommend matching the product identification information on the unit to the details shown in the 917270911 owner's manual.

We use the tractor’s identification information (not just the model number) to narrow the manufacturing year.

• Locate the product identification label (typically under the seat, on the frame, or near the engine area)
• Write down the serial number exactly as shown
• Compare the serial number format and any date codes to the identification guidance in the manual
• If the tractor has an engine model/type code plate, record that too (engine codes can help confirm timeframe)
• Keep the deck and chassis numbers handy if you are ordering parts like blades, belts, or steering components

The build year affects parts compatibility for common wear items such as the mower deck blade, ground drive belt, steering linkage, and lift components. Even within the same Craftsman model family, small production changes can affect which part number fits.

• Confirm your deck size and blade mounting style
• Check belt routing and measure the old belt if it is missing or shredded
• Match steering and lift parts by diagram callout when possible
