Can I use premium gas in my lawn mower?
Yes, you can use premium gas in your Craftsman 917388114 mower, but it is not needed for normal operation. For best results, use fresh, clean regular unleaded gasoline and avoid storing fuel from one season to the next; stale fuel is a common no-start cause.
What we recommend for fuel on model 917388114
- Use fresh regular unleaded gasoline for everyday mowing.
- Buy fuel in small quantities so it gets used up quickly.
- Do not store gasoline from one season to another.
- Keep your gas can clean and replace it if it starts to rust (rust and dirt cause fuel problems).
- If the mower will sit, use a fuel stabilizer and follow the storage steps in the owner's manual.
Why premium gas usually does not help
Premium fuel mainly provides higher octane. Most walk-behind mower engines are designed to run correctly on regular unleaded, so higher octane typically does not improve power, starting, or engine life.
If the mower will not start after sitting (fuel-related checks)
Stale fuel and contamination are frequent issues. Before deeper repairs, we recommend these quick checks:
- Drain old fuel and refill with fresh gasoline.
- Check for water in fuel (often shows up after long storage).
- Inspect the air filter; a dirty filter can prevent starting.
- Confirm the spark plug wire is firmly connected.
- If you recently hit something, check for a loose blade or a damaged blade adapter.
Common fuel symptoms and what they point to
| Symptom | Most likely fuel issue | What to do first |
|---|---|---|
| Starts then dies | Stale fuel or water in fuel | Replace fuel with fresh gasoline |
| Will not start after storage | Stale fuel | Drain tank and refill |
| Runs rough | Contaminated fuel | Replace fuel; clean/replace gas can |
Why it matters
Using fresh fuel and storing it correctly helps prevent hard starting, rough running, and carburetor problems. It also reduces downtime and helps your mower deliver consistent cutting performance.

Does anyone make a 36 inch zero turn mower?
Yes. 36-inch zero-turn mowers are made by multiple brands and are a common choice when you need zero-turn maneuverability but also need a narrower deck to fit through gates or handle tighter yards. They are a different mower type than the Craftsman 917388114 walk-behind.
What “36-inch zero-turn” usually means
A 36-inch zero-turn is a riding mower with a 36-inch cutting deck and lap-bar style steering (or similar) that can pivot in place.
- Fits many smaller gates and sheds better than 42-inch and larger decks
- Turns tightly around trees, beds, and hardscape
- Cuts faster than most walk-behind mowers on larger lawns
- Typically costs more than a walk-behind because of the drive system and deck design
How to decide if a 36-inch zero-turn is the right size
Measure first so you do not buy a deck that will not fit where you need it.
| What to measure | What to look for | Why it matters |
|---|---|---|
| Narrowest gate opening | Clearance beyond deck width | Deck width is not the same as overall mower width |
| Storage door opening | Overall machine width | Some 36-inch units are wider than 36 inches |
| Yard obstacles | Turning space | Zero-turns excel in tight layouts |
| Terrain | Slope and traction needs | Steeper slopes can require different tires or a different mower type |
If you are comparing to your Craftsman 917388114 walk-behind
Your Craftsman 917388114 is designed around safe walk-behind operation, including an operator presence control bar and required guarding. For operating and safety basics (especially around rotating blades and discharge), follow the owner's manual.
Why it matters
A 36-inch zero-turn can save time, but it also changes how you mow, store, and maintain equipment. If your main issue is cut quality on the Craftsman walk-behind, a sharp blade and solid blade mounting often make a bigger difference than changing mower types.

What model number is the Craftsman 42 riding mower?
The Craftsman model on this page is 917388114, and it is a gas walk-behind rotary lawn mower (21-inch deck), not a 42-inch riding mower. For model-number identification and where to find the ID decal on the mower housing, use the owner's manual.
How to identify the correct model number
For Craftsman equipment, the model number you need is the one on the product’s model/serial decal (not the deck size or a store listing name).
- Look for the decal on the rear of the mower housing (common location for model 917388114).
- Write down both the model number and serial number.
- Use the full model number with all digits (example: 917388114).
- If you are trying to identify a 42-inch riding mower, check the decal under the seat area, on the frame, or near the engine (typical riding mower locations).
Walk-behind mower vs. 42-inch riding mower: quick comparison
| Feature | This page’s model | Typical 42-inch riding mower |
|---|---|---|
| Model number shown in manual | 917388114 | Varies by tractor |
| Mower type | Walk-behind | Riding mower/tractor |
| Cutting width | 21-inch | 42-inch |
| Common parts you shop for | Blade, blade adapter, wheels, control cable | Deck belts, spindles, pulleys, blades |
Why it matters
Using the wrong model number is the fastest way to order the wrong blade, cable, or hardware. Once you match the exact model on the decal, the parts diagrams and part numbers line up correctly.
