How to find Craftsman model number?
On the Craftsman gas walk-behind lawn mower model 917377662, the model number is typically printed on an ID sticker or plate on the mower deck. For most Craftsman walk-behind mowers, you will find it on the rear portion of the deck near the handle mounting area; confirm the exact label location in the 917377662 owner's manual.
Where to look on the mower
Check these common spots first (wipe off grass and dirt so the label is readable):
- Back of the mower deck, between or near the lower handle mounts
- Rear of the deck just above the discharge area (if equipped)
- Top of the deck near the engine mounting area (less common)
- Side of the deck near a rear wheel (less common)
What to write down (and why)
Record the full model number and any serial or product number shown on the label.
- Model number: identifies the exact mower version so diagrams and parts match
- Serial number: helps confirm production run details when parts changed mid-series
- Engine model/type/code (if listed on the engine): helps when ordering engine-specific items
Quick ID checklist
Use this to make sure you are capturing the right information.
| Item on label | What it’s used for | Example format |
|---|---|---|
| Model number | Finds the correct parts list and diagrams | 917.XXXXXX or 917XXXXXX |
| Serial number | Confirms production run | Letters and numbers |
| Engine ID | Matches engine parts (spark plug, carb parts) | Model/type/code |
Why it matters
Craftsman walk-behind mowers often share similar decks and handles, but small differences (drive system, gear case, control cable routing) can change which belt, pulley, or hardware fits. Using the exact model number helps us match the right Craftsman parts the first time.

Should I use 87 or 91 gas for lawn mower?
For the Craftsman 917377662 gas walk-behind lawn mower, 87-octane (regular) gasoline is the right choice for normal operation. Higher octane (like 91) is not “better” for this type of small engine; it is mainly used for engines designed for higher compression.
What to use (and what to avoid)
- Use fresh, clean 87-octane unleaded gasoline.
- Avoid stale gas; it is a common cause of no-start and poor performance.
- Keep fuel clean and dry; water or dirt in fuel can cause hard starting and surging.
- Do not store gasoline from one season to the next.
- Replace old or rusty gas cans; rust and debris can contaminate fuel.
Quick decision guide
| Situation | Best choice | Why |
|---|---|---|
| Weekly mowing, normal temps | 87 octane | Correct for typical mower engines and reliable starting |
| Fuel has been sitting for weeks/months | Drain and refill with fresh 87 | Stale fuel commonly causes no-start and loss of power |
| Suspected water/dirt in fuel | Empty tank and refill with fresh 87 | Contamination leads to rough running and starting issues |
If the mower won’t start after refueling
The troubleshooting chart for this mower lists fuel-related causes like out of fuel, stale fuel, and water in fuel. Use these checks first:
- Confirm the tank has fresh gasoline.
- Check the spark plug wire is firmly connected.
- Inspect and clean or replace the air filter if dirty.
- If fuel is old, empty the tank and refill.
- Follow the starting steps and control locations in the 917377662 owner's manual.
Why it matters
Using the correct fuel and keeping it fresh helps prevent carburetor and starting problems, reduces downtime, and supports consistent power under load. Most “needs premium gas” symptoms are actually caused by stale fuel, contamination, or maintenance items.

What year is Craftsman Model 917377662?
Craftsman model 917377662 is a model number, not a date code; it does not directly tell the year. To find the year, we use the mower’s product identification label (often on the deck or rear housing) and decode the serial number/manufacturing code using the Craftsman 917377662 owner's manual.
Where to find the date information
On most Craftsman gas walk-behind mowers, the build date is tied to the serial number or a separate manufacturing code, not the 917.xxxxx model.
Check these common locations:
- Top of the mower deck near the engine mount
- Rear of the deck near the discharge opening
- Under the handle mounting area
- On a label near the drive cover or wheel height adjuster
How to decode it (what to look for)
Many Craftsman mowers use a code that includes a month/day/year pattern, but the exact format varies by production run. Use the label information and compare it to the identification section in the manual.
| What you have | What it tells you | What to do next |
|---|---|---|
| Model number (917377662) | Parts fit and diagrams | Use it to match parts and assemblies |
| Serial number / date code | Build date (year) | Decode using the manual’s ID guidance |
| Engine model/type code | Engine build info | Use for engine-specific parts and service |
Why it matters
Knowing the year helps us match the correct drive system, handle hardware, and gear case variations that can change across production runs, even when the model family looks similar.
Related parts you may see referenced in diagrams
If you are already looking at the drive or handle area while checking the label, these are common items shown in the parts list for model 917377662:
