Should I use 87 or 93 for lawn mower?
For the Craftsman lawn mower model 917389060, use fresh, clean regular unleaded gasoline with a minimum of 87 octane (AKI). Using 93 octane is not required for normal operation; it typically will not improve power or reliability in a standard 4-cycle mower engine.
What we recommend for fuel (and what to avoid)
- Use 87 octane (AKI) or higher; 87 is the normal choice for most walk-behind mowers.
- Buy fuel in small amounts; gasoline can start degrading in about 30 days.
- Keep fuel clean and dry; water or dirt in the can causes hard starting and surging.
- Avoid old fuel left over from last season unless it was stabilized and stored correctly.
- If you mow at higher altitude and notice pinging or power loss, follow the fuel guidance in the 917389060 owner's manual.
Quick comparison: 87 vs 93 in a mower
| Fuel choice | When it makes sense | What you should expect |
|---|---|---|
| 87 octane (AKI) | Normal mowing, most conditions | Correct performance for this mower |
| 93 octane (AKI) | Only if a specific engine issue requires it (uncommon) | Usually no noticeable benefit |
Fuel-related tips that prevent common starting problems
- If the mower has been sitting, drain the tank and refill with fresh fuel before troubleshooting.
- Check the spark plug wire is firmly connected before starting.
- If the engine runs rough after refueling, inspect the air filter and consider cleaning the carburetor.
- Keep the blade sharp so the engine is not overloaded; a dull blade can make the mower feel underpowered.
Helpful DIY guidance
If you are dealing with stale fuel symptoms (hard start, stalls, surging), follow the steps in how to keep lawn mower gas from going bad.
Why it matters
Using the right octane and fresh fuel helps your 917389060 start easier, run smoother, and reduces carburetor varnish buildup that leads to no-start and poor performance.

What model number is the Craftsman 917389060?
The model number for this Craftsman walk-behind gas lawn mower is 917.389060 (often written without the dot as 917389060). You can confirm it on the model identification page of the Craftsman 917389060 owner's manual.
Where to find the model number on the mower
We recommend checking the mower’s model tag first, then matching it to the manual.
- Look on the rear of the deck near the discharge opening
- Check the back panel/rear skirt area
- Inspect the handle mounting area (near the lower handle brackets)
- Compare the tag to the cover page of the manual for an exact match
Model number vs. engine model number (common mix-up)
This mower uses a Briggs & Stratton engine, which has its own separate engine model number. The mower model number is what you use for Craftsman parts lookups.
| What you’re identifying | Example format | Used for |
|---|---|---|
| Mower model number | 917.389060 (or 917389060) | Deck, blade, wheels, handle, cables |
| Engine model number | 126T02-1225-EA (example format) | Engine-specific parts like carburetor or recoil starter |
Why it matters
Using the correct mower model number ensures you get the right fit for parts like the blade adapter, zone control cable, and hardware. For example, the parts list for model 917.389060 includes items such as the lawn mower 21-in deck mulching blade 532406706 and the lawn mower zone control cable 532183281.

Where can I find the Craftsman mower model number?
On the Craftsman walk-behind mower model 917389060, the model number is printed on a decal located on the rear of the lawn mower housing. We recommend writing down both the model number and the serial number from that same decal before ordering parts.
Where to look on the mower
Check these common spots first:
- Rear of the mower deck (rear housing area), on a decal
- Near the rear discharge door or rear skirt area
- On the handle support area close to the deck (less common)
- Under grass buildup; wipe the area clean to reveal the decal
What the label typically shows
The decal usually includes more than just the model number.
| Label item | What it’s used for |
|---|---|
| Model number (example: 917389060) | Identifies the correct parts list for the mower |
| Serial number | Helps match production variations |
| Engine info (often Briggs & Stratton) | Helps when ordering engine-specific parts |
Tips to record it correctly
Small character differences matter when matching parts.
- Copy the model number exactly as printed (including dots if shown)
- Record the serial number from the same decal
- Take a clear photo of the decal for reference
- Use the model number when selecting parts like the blade adapter, wheels, and control cable
Why it matters
Craftsman walk-behind mowers can use different handles, wheels, blades, and hardware depending on the exact model and production run. Using the correct model number prevents ordering a blade, mulcher door, or fastener that does not fit.
