Craftsman 917256670 lawn tractor Parts

A Craftsman “6.75” walk-behind mower is identified by the model number on its model tag, not by the 6.75 rating. For your Craftsman riding lawn tractor documentation, the model shown is 917256670; use the mower’s own tag to confirm the correct walk-behind model number.

Look for a sticker or metal tag on the mower; common locations include:

• Rear of the deck near the wheel height adjuster
• Under the rear discharge flap (if equipped)
• On the handle support or rear frame crossbar
• Near the engine mounting area on the deck

For the riding tractor model 917256670, the manual notes the tractor model plate is located under the seat; see the 917256670 owner’s manual.

“6.75” is typically an engine power rating used on many different Craftsman walk-behind mowers. Multiple model numbers can share the same rating, so the rating alone is not enough to identify parts.

Use this information from the mower tag when looking up parts:

• Full model number (usually 9 digits, sometimes with a prefix)
• Product type (walk-behind mower vs. riding tractor)
• Deck size (often 21 in. on many 6.75 walk-behind mowers)
• Engine model number (separate from the mower model)

Using the exact model number prevents ordering the wrong blade, air filter, carburetor, or drive belt, especially when several Craftsman mowers share similar deck sizes and engine ratings.

For a Craftsman lawn tractor like model 917256670, a full engine replacement typically costs $800 to $2,500 installed (engine plus labor). The engine itself is usually the biggest cost; labor commonly runs 4 to 8 hours depending on shop rates and what else needs attention.

• Engine type and horsepower: higher HP and OEM engines cost more.
• Labor time: removing the hood, wiring, fuel line, exhaust, and drive components adds time.
• Extra parts and fluids: oil, filter, fuel line, clamps, spark plug, and gaskets are often replaced during the job.
• Condition of the tractor: rusted fasteners, damaged wiring, or worn pulleys can add labor.
• Shop rate in your area: hourly rates vary widely.

Engine replacement is usually the right call when the engine has internal damage (knock, low compression, heavy smoke) or repeated failures. If the tractor still drives well and the deck and steering are solid, a new engine can extend the machine’s life significantly.

Use the 917256670 owner’s manual to confirm where the tractor model plate is located and to identify the engine model number on the blower housing; engine swaps must match mounting pattern, crankshaft size, and electrical connections.

• Verify the battery and cables are clean and tight
• Confirm safety interlock switches are working
• Check for fuel delivery issues (stale fuel, clogged filter)
• Inspect ignition and spark plug condition
• Make sure the engine is not hydro-locked (fuel in cylinder)

For no-crank symptoms, we also recommend riding lawn mower engine clicks but doesnt turn over video as a fast diagnostic walkthrough.

An engine replacement is one of the highest-cost repairs on a riding mower. Confirming the engine model number and ruling out starting or fuel issues first helps you avoid buying an engine when a smaller repair restores normal operation.

The Craftsman lawn tractor model 917256670 uses a gasoline internal-combustion engine. Craftsman tractors in this series were built with different engine suppliers over time, so the correct way to identify your exact engine (make, horsepower, and spec numbers) is to read the engine ID tag and confirm it against the 917256670 owner's manual.

Use the engine’s identification label, not the tractor hood decal.

• Look for an ID tag on the blower housing, valve cover, or near the starter
• Record every field exactly as shown (model, spec, and serial or code)
• Clean the tag area first so numbers are readable
• Use the engine ID when ordering carburetor, starter, ignition, or charging parts
• Match the ID to the engine section and parts lists in the manual

Different manufacturers format IDs differently; these are the most common patterns.
