Craftsman 917377151 gas walk-behind lawn mower Parts

Craftsman model 917377151 is identified by its model number, not by a built-in “year” code. For this mower, the most reliable way to confirm the production timeframe and exact specifications is to reference the model-specific documentation in the 917377151 owner's manual.

Many Craftsman walk-behind mowers do not encode the build year in the model number itself. Instead, the year is typically determined by one of these identifiers:

• Engine model and code (often stamped on the Briggs and Stratton engine shroud or valve cover area)
• Product/serial label on the mower deck or rear housing (if present)
• Date code on certain components (varies by supplier)
• Purchase date on your receipt (useful for warranty and parts history)

Use this list to find the information that actually dates the mower:

• Check the engine identification label (engine model, type, and code)
• Look for a sticker or stamped tag on the deck near the rear wheels or discharge area
• Record the full model number exactly as shown: 917377151
• Match your findings to the diagrams and specs in the 917377151 owner's manual

The “month, day, year” format people mention online usually applies to a separate date code (often on an engine or a serial tag), not the Craftsman mower model number.

Getting the year right helps us match the correct blade, drive belt, throttle/control parts, and other wear items for your exact configuration, especially when a model has running changes.

For a Craftsman walk-behind mower like model 917377151, the fastest way to identify what you have is to read the model and serial number decal on the mower housing, then use that model number to match the correct mower parts diagram and the correct engine parts diagram in the 917377151 owner's manual.

On this Craftsman mower, the model and serial numbers are listed on a decal attached to the rear of the lawn mower housing.

• Tip the handle up and look at the back of the deck (rear housing area)
• Wipe off grass and dirt so the decal is readable
• Write down both the model number and the serial number
• Record the date of purchase if you still have it (helpful for service and parts)
• Use the model number to confirm you are ordering parts for the correct mower platform

Most walk-behind mowers use two separate parts breakdowns:

• Mower (chassis/deck) parts: blade, wheels, drive belt, height adjusters, controls
• Engine parts: spark plug, air filter, carburetor parts, recoil starter, ignition parts
• The engine model is typically shown on the engine shroud or valve cover label

Once you confirm model 917377151, you can match high-wear items to the correct diagrams and hardware.

• Blade and blade mounting parts (example: lawn mower blade 532406713)
• Self-propel drive components (example: belt 532157769)
• Wheel and height adjuster pieces
• Control assemblies and cables
• Fasteners and washers used on the deck and handle

Using the exact mower model number prevents ordering the wrong blade, belt, or drive parts. Using the engine model prevents mismatching tune-up items like the spark plug and air filter.

For the Craftsman 917377151 gas walk-behind lawn mower, we recommend using fresh 87-octane (regular) unleaded gasoline; higher octane (89 or 91) is fine but does not improve performance in a properly running mower engine. For fuel and storage guidance specific to this mower, follow the 917377151 owner's manual.

• Use fresh, clean unleaded gasoline from a busy station.
• 87 octane is the standard choice for walk-behind mower engines.
• 89 octane is acceptable, but it is typically unnecessary.
• Avoid using old fuel; stale fuel is a common no-start cause.
• Keep the gas can clean; rust or dirt in the can leads to fuel system problems.

Stale fuel, water in fuel, and restricted airflow are more common than “wrong octane.” Check these first:

• Confirm the tank has fresh fuel (not last season’s gas).
• Inspect the air filter; a dirty filter can cause hard starting and power loss.
• If you suspect drive issues rather than engine issues, use the lawn mower wont move troubleshooting video motion drive failure.

Using the right fuel is mainly about cleanliness and freshness, not premium octane. Fresh gas helps prevent hard starting, surging, and carburetor varnish; clean storage practices also reduce rust and debris that can clog the fuel system.

The model number for this Craftsman gas walk-behind lawn mower is 917.377151; it’s printed on the mower’s model tag and shown on the cover of the 917377151 owner’s manual. Use this exact number when ordering parts like a blade, belt, or throttle.

We typically see the model number in one of these spots on Craftsman walk-behind mowers:

• On the rear of the deck near the discharge door
• On the deck top surface near the engine mounting area
• On a label near the handle mounting brackets
• In the manual’s front pages and repair parts sections

Craftsman model numbers can look similar, but parts and assemblies can differ by deck style, drive system, and engine setup. Using 917.377151 helps match the correct drive components, hardware, and cutting parts.

• Confirm the model tag reads 917.377151 (including the dot)
• Match the part description to your mower’s feature (rear discharge, self-propel)
• Compare your old part’s shape and mounting points to the diagram in the 917377151 owner’s manual

The right model number prevents wrong-part returns and gets your mower back to cutting and driving correctly the first time.
