Craftsman 917377661 gas walk-behind lawn mower Parts

To identify what kind of lawn mower you have, match the brand and model number on the mower’s ID label to the diagrams and specifications in the 917377661 owner's manual. For Craftsman model 917377661, you will typically use one parts breakdown for the mower and a separate one for the engine.

Most walk-behind mowers have an ID label on the mower housing or rear deck area. Once you find it, write down:

• Brand name (Craftsman)
• Model number (example: 917377661)
• Product type (gas walk-behind lawn mower)
• Any engine brand and engine model/type code (often on the engine shroud)
• Serial number (helpful for production variations)

A gas walk-behind mower is really two systems bolted together: the mower chassis and the engine. That is why you often see:

• Mower parts: handle, wheels, drive system, deck, blade hardware, grass catcher or mulcher plug
• Engine parts: carburetor, air filter, ignition, recoil starter, fuel system

This matters because ordering the correct replacement part depends on whether the part belongs to the mower frame or the engine.

Use these features to describe your mower accurately when shopping parts or troubleshooting:

• Drive type: self-propelled (has a drive control lever) vs. push
• Discharge style: rear bagging, side discharge, mulching (many ship ready to mulch)
• Height adjustment: single-point height adjuster vs. individual wheel adjusters
• Starting system: recoil pull start (starter handle) vs. electric start

Using the exact model number and the correct diagram prevents wrong-part returns and speeds up repairs, especially for common wear items like blades, belts, and wheels.

For a Craftsman gas walk-behind mower like model 917377661, we look up the correct parts by matching the model number from the mower’s ID label to the parts diagrams and lists in the 917377661 owner’s manual. Once you have that number, you can reliably identify the right blade, belt, drive parts, and decals.

On most Craftsman walk-behind mowers, the model number is printed on a label or stamped into the metal on the mower body. Check these common spots:

• Rear of the mower deck (near the back wheels)
• Top of the deck near the engine mounting area
• Under the rear discharge door or near the bagging opening
• On the handle support brackets (left or right side)
• Near the drive cover area (if your mower is self-propelled)

Once you find the model number, match it exactly (including all digits). Then use it to cross-check parts by description and diagram callout.

• Confirm the model number matches 917377661
• Use the parts list to identify the assembly (handle, drive, gear case, deck)
• Match the part description to the symptom (for example, drive issues often point to belt, pulley, or gear case components)
• Verify fasteners and small hardware (washers, E-rings, lock nuts) by diagram position

Craftsman model numbers are the key to correct fit. Many walk-behind mowers look similar, but use different drive belts, pulleys, and handle parts; using the exact model number avoids returns and repeat repairs.

For Craftsman gas walk-behind lawn mower model 917377661, the serial number is primarily used to identify your exact unit for parts and service records; we recommend recording it along with the purchase date as shown in the 917377661 owner's manual.

The model and serial numbers are printed on a decal on the rear of the lawn mower housing.

• Shut the engine off and let the muffler cool completely
• Tip the handle back slightly to access the rear housing area (do not tip the mower on its side unless the manual instructs it)
• Locate the decal on the rear of the deck/housing
• Write down the model number (917377661) and the serial number
• Record the date of purchase for your maintenance and parts history

Craftsman serial-number formats vary by product line and production run, so the safest approach is to use the serial number as an identifier rather than relying on one universal “MMDDYY” date code.

• Confirm you are ordering parts for the correct mower version
• Provide the number when requesting service or troubleshooting help
• Match decals and assemblies when comparing parts diagrams

Using the correct serial number and model number helps prevent ordering the wrong drive, handle, or control components, especially on walk-behind mowers where small design changes can affect fit.

The model number 917377661 identifies the mower family, not the build year by itself. To find the year for your Craftsman 917377661 gas walk-behind mower, we use the product identification (serial) number date code shown in the 917377661 owner's manual; that code is what tells the exact manufacturing date.

Look for the product ID/serial label and record the full serial number before decoding it.

Common label locations on a walk-behind mower:

• Rear of the deck near the discharge opening
• Top of the deck behind the engine
• Near the rear wheels or height adjuster area
• On the handle bracket area

Many Craftsman walk-behind mowers use a 6-digit date code within the serial number:

• First 2 digits: month
• Next 2 digits: day
• Last 2 digits: year

Knowing the exact year helps us match the correct parts and diagrams for your mower, especially for drive components like the gear case and belt system. For example, the parts list for model 917.377661 includes the gear case upper housing (listed as “Case, Upper”) and related drive hardware, which can vary by production run.

If you are troubleshooting drive issues while you’re checking the ID label, the manual’s drive section also points to common checks such as inspecting the drive belt and adjusting the drive control. A frequently replaced drive component on this model is the case, upper 532187531.

On a Craftsman walk-behind mower, the model number is on the mower’s product ID label (not on the engine). For your mower, the model number you want for most replacement parts is 917377661; confirm the label location using the 917377661 owner's manual.

Check these common label locations first (wipe off grass and dirt so you can read it):

• Rear of the mower deck near the discharge opening or rear door
• Top of the deck near the engine mounting area
• Back of the deck near the height-adjuster brackets
• Handle support area (lower handle brackets)
• Under the rear flap near the bagging or mulching opening

Your Craftsman mower uses a Briggs & Stratton engine, which has its own engine model/type/code. Use the mower model number for chassis, drive, and handle parts; use the engine model number for engine-specific parts.

• Write the number exactly as shown; include all digits
• Ignore paint codes and decal numbers
• If the label is damaged, compare the parts diagrams in the 917377661 owner's manual to confirm you have the right model

The mower model number (917377661) ties to the correct parts diagrams and part numbers for your specific deck and drive configuration. That prevents ordering look-alike parts that do not fit.
