Craftsman 917288720 tractor Parts

Replacing the engine on a Craftsman riding mower like model 917288720 typically costs $1,200 to $3,500 total (engine plus labor). The wide range comes from engine size/type, whether you choose new vs. used, and how much shop time is needed for wiring, pulleys, and belt alignment.

Most engine-replacement quotes are a mix of parts cost and labor time. Common cost drivers include:

• Engine type and horsepower (single-cylinder vs. V-twin)
• Crankshaft specs (diameter/length/keyway) and pulley compatibility
• Electrical system match (charging output, connectors, safety interlocks)
• Fuel system work (tank/line condition, carb setup)
• Extra wear items discovered during the swap (belts, idlers, battery cables)

These ranges are typical for riding lawn tractors in this class.

The exact engine replacement cost for 917288720 depends on the engine currently installed and the crankshaft and mounting specs; those details are confirmed by checking the engine ID tag and the specifications section in the 917288720 operator's manual.

If your tractor is also slipping, squealing, or has blade-drive issues, it can be smart to price related wear items at the same time, such as the lawn tractor ground drive or blade drive belt, 1/2 x 92-2/5-in 592855201.

An engine swap can exceed the value of an older tractor, but it can still be the best choice when the deck, transmission, and steering are in good shape. Getting the correct crankshaft and electrical match prevents repeat labor and premature belt or pulley wear.

On the Craftsman front-engine lawn tractor model 917288720, the model number is typically found on an ID label on the tractor frame under the seat, or on the underside of the seat itself. Once you have that number, you can match the correct diagrams, parts, and maintenance info in the 917288720 operator’s manual.

Check these common label locations first:

• Under the seat on the frame rail (lift the seat and look down at the chassis)
• On the underside of the seat pan
• Near the rear fender area close to the seat mounting points
• On the frame near the engine compartment (less common, but worth a quick look)
• On a sticker or metal tag that also lists a serial number

For parts lookup and service, we recommend recording:

• Model number (for this page: 917288720)
• Serial number (helps confirm production run and correct variations)
• Any product number or manufacturing code shown on the same label

If the tag is damaged, you can often still narrow it down by comparing key components (deck size, controls, and drive system) to the diagrams and specs in the 917288720 operator’s manual.

Using the exact model number prevents ordering the wrong belt, blade, switch, or hardware. Even small differences between similar Craftsman tractors can change which parts fit and how they install.

For Craftsman lawn tractor model 917288720, the operator’s manual describes a 25.0 HP gas-powered tractor with a low-emission internal combustion engine. The manual does not identify the engine manufacturer or engine model; the most accurate way to confirm is by reading the engine ID label and cross-checking it with the 917288720 operator’s manual.

Use the engine’s ID tag to match tune-up and fuel-system parts correctly.

• Lift the hood and find the engine identification label.
• Write down the manufacturer, model, type, and code/spec.
• Use that engine ID when selecting spark plug, air filter, fuel filter, and oil filter.
• Keep the tractor model (917288720) handy for chassis and deck parts.
• If the label is missing or unreadable, a technician can often identify the engine by casting numbers and configuration.

These items are listed in the product specifications section of the manual for model 917288720.

The tractor model number helps with deck, steering, and drive components, but the engine ID determines the correct maintenance parts and settings. Matching by engine ID helps prevent wrong-part returns and hard-start or rough-running problems.
