How do I find out what kind of lawn mower I have?
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.
Where to find the model information
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)
Why there are usually two parts diagrams
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.
Quick checks that confirm the “type” of mower
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
| What you’re identifying | What to look for | Why it helps |
|---|---|---|
| Mower model | Deck ID label | Matches the correct mower diagrams |
| Engine model | Engine label/shroud | Matches the correct engine diagrams |
| Key features | Drive lever, mulcher plug, bagger | Narrows the right parts and instructions |
Why it matters
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.

How to look up Craftsman model number?
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.
Where to find the model number on a walk-behind mower
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)
How we use the model number to look up parts
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
Example: model-specific parts you can identify in the manual
| What you’re looking up | Example part type shown for 917377661 | Why it helps |
|---|---|---|
| Self-propel drive issues | Drive cover, V-belt, pulleys, gear case | Prevents ordering the wrong drive system parts |
| Handle hardware | Handle knob, rope guide, bolts | Ensures correct fit and thread size |
| Gear case components | Case halves, seals, washers | Helps pinpoint leaks or loss of drive |
Why it matters
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.

How to read a Craftsman serial number?
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.
Where to find the serial number on model 917377661
The model and serial numbers are printed on a decal on the rear of the lawn mower housing.
Quick steps
- 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
How to interpret the serial number format
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.
What you can reliably do with the serial number
- 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
Serial number vs. model number (what’s the difference?)
| Item | What it tells us | Example for this mower |
|---|---|---|
| Model number | The mower design family and parts breakdown | 917377661 |
| Serial number | Your mower’s unique build identifier | Found on rear housing decal |
Why it matters
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.

What year is the Craftsman 917377661?
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.
How to find the year on your mower
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
How the date code is typically formatted
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
Example (how to read it)
| Date code | Month | Day | Year |
|---|---|---|---|
| 072811 | 07 | 28 | 2011 |
Why it matters
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.

Mower model number vs. engine model number (important)
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.
| You need parts for | Use this number | Example parts |
|---|---|---|
| Mower deck, wheels, drive system, handle | Craftsman mower model: 917377661 | belt, gear case, wheels, handle knobs |
| Engine (carburetor, ignition, recoil, etc.) | Briggs & Stratton engine model (on engine shroud/cover) | air filter, carb kit, spark plug |
Quick tips to read the label correctly
- 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
Why it matters
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.
