Craftsman 917376543 lawn mower Parts

A “Craftsman 6.75” label usually refers to the engine rating, not a single mower model number. For the Craftsman walk-behind mower shown on this page, the model number is 917.376543 (often written without the dot as 917376543); you can confirm it on the rear housing decal and in the 917376543 owner's manual.

Where to find the model number on the mower

We use the mower’s model number (not the engine label) to match the correct diagrams, blade, belt, and drive parts.

• Look for a decal on the rear of the mower housing
• Record the model number and serial number from that decal
• Use the model number when ordering common wear items like a blade, belt, or wheel
• If the decal is dirty or faded, wipe it clean and use a flashlight at an angle

“6.75” vs. mower model number: what’s the difference?

“6.75” is commonly used as an engine power identifier on older walk-behind mowers; the mower model number identifies the complete unit (deck, drive system, handle, and controls).

What you see	What it identifies	What to use it for
6.75 (engine label)	Engine power family	General engine reference only
917.376543 / 917376543	Complete Craftsman mower	Parts lookup, diagrams, manual
Serial number	Your exact unit	Warranty and service records

Why it matters

Using the correct model number prevents ordering the wrong blade, ground drive belt, or transmission parts. For example, this model uses a 22-inch 3-in-1 blade option such as the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825, which must match the deck and adapter setup.

For the Craftsman 917376543 gas walk-behind mower, we recommend clean, fresh, unleaded gasoline with a minimum 87 octane (87 AKI). Avoid old fuel; stale gas is a common reason a mower will not start. Confirm any model-specific fuel notes in the 917376543 owner's manual.

Fuel to use (and what to avoid)

Use fuel that helps protect the carburetor and keeps starting easy.

• Use fresh, unleaded gasoline (87 AKI or higher)
• Use fuel with up to 10% ethanol (E10)
• Do not use stale fuel from last season
• Do not use fuel contaminated with water, rust, or dirt (dirty cans cause problems)
• Store gas only in a clean, approved gas can; replace the can if it starts to rust

Quick guide: what’s OK vs not OK

Fuel choice	Recommended?	Why
Fresh unleaded 87 AKI (regular)	Yes	Reliable starting and normal performance
Unleaded with up to 10% ethanol (E10)	Yes	Common pump fuel; acceptable for small engines
Old gas (weeks to months old)	No	Causes hard starting, rough running, and deposits
Gas with water or debris	No	Leads to no-start and fuel system damage

Why it matters

Fuel quality directly affects starting, power, and engine life. The mower’s troubleshooting guidance lists stale fuel and water in fuel as common causes of a no-start condition, so using fresh gas is one of the fastest ways to prevent downtime.

Helpful tips for storage and seasonal use

• Do not store gasoline from one season to the next
• Let the engine cool before storing the mower indoors
• Keep the mower clean; built-up debris can make the engine run hotter
• If you need off-season prep steps, follow the storage section in the 917376543 owner's manual

On your Craftsman walk-behind mower model 917376543, the model number is printed on a decal on the rear of the lawn mower housing. Use that exact model number when ordering non-engine parts so you get the correct blade, belt, wheels, and handle components.

Where to look on model 917376543

Check these common decal locations first:

• Rear of the mower deck housing (most common on this model)
• Back panel area just above the discharge opening
• Near the height-adjustment area on the rear axle support
• On the handle mounting bracket area (less common)

If the decal is dirty or faded, wipe the area with a damp rag and mild soap, then dry it and re-check.

What numbers to record (and why)

We recommend writing down both the model and serial information from the decal.

• Model number: identifies the mower platform (used to match parts diagrams)
• Serial number: helps confirm production run details when parts changed mid-series
• Date of purchase: useful for maintenance tracking and warranty timing

Quick reference

Why it matters

Craftsman walk-behind mowers often share similar-looking decks and handles, but parts like the drive belt, blade, and deflector can differ by model. Using the exact model number prevents ordering the wrong fit.

For model-specific diagrams and identification notes, use the 917376543 owner's manual.
