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.

Where to find the 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.

What “6.75” means (and why it can be confusing)

“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.

Quick ID checklist

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)

Model number vs. engine model number

Item	What it identifies	Where it’s found
Mower model number	The mower and its parts diagrams	Mower frame/deck tag
Engine model number	The engine and engine-specific parts	Engine blower housing

Why it matters

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.

What drives the total price

• 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.

Typical cost breakdown (installed)

Cost item	Typical range	Notes
Replacement engine	$500 to $2,000	Most of the total cost
Labor	$300 to $900	Often 4 to 8 hours
Misc. parts and fluids	$25 to $150	Oil, filter, clamps, tune-up items

When replacement makes sense vs. repair

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.

Before you buy an engine

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.

Quick checks that can avoid an engine swap

• 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.

Why it matters

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.

How to identify the exact engine on model 917256670

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

What the engine ID typically looks like

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

Engine brand	What you usually see on the tag	What it’s used for
Briggs & Stratton	Model / Type / Code	Tune-up parts and build date
Kohler	Model / Spec / Serial	Correct carburetor and ignition parts
Tecumseh (older units)	Model / Spec / DOM	Service parts and settings

Why it matters

The tractor model number 917256670 identifies the chassis, deck, and drive system. The engine ID identifies the exact engine build so you get the right air filter, spark plug, carburetor, and starter parts the first time.

Parts that may relate to engine service on this model
