Each year, about 80,000 Americans visit emergency rooms for lawn mower injuries — and the vast majority of those accidents were completely preventable.
Staying safe is simple: always wear proper eye and hearing protection, clear your yard of hidden debris before starting, and never let children ride on the machine.
If you’d rather leave the mowing to someone else, Lawn Love connects you with local pros who handle it for you — no risk, no hassle.
| Key takeaways |

| • Wear safety glasses, hearing protection, and closed-toe shoes every time. • Clear debris before mowing; rocks and sticks can turn into 200 mph projectiles. • Keep children and pets out of the mowing area until you’re completely done. • Mow forward whenever possible. Reversing near children is the leading cause of riding mower fatalities. |
1. Wear proper safety gear
Proper protective gear is your only defense against flying debris and loud equipment.
Andrew Day, owner of Advanced Quality Lawn in Northeast Ohio, says, “If I had to pick only two or three gear items that actually matter, it would be real eye protection, hearing protection, and snug shoes with firm soles(not slides/crocs) for footing and to avoid getting toes under the deck edge when you pivot.”
Hearing protection is particularly crucial because gas mowers produce up to 100 decibels — well above the 85-decibel threshold for permanent hearing damage.
Yet, Kevin Thompson, owner of Sylvan Scapes in Staunton, VA, says homeowners frequently skip it, “underestimating the permanent, cumulative nerve damage caused by the high decibel output.”
| Gear | What it does |
| Dust mask | Keeps dirt and pollen out of your lungs |
| Hat with a visor | Provides shade and protects from the sun |
| Long sleeves and pants | Protects arms and legs from flying debris |
| Heavy shoes | Prevents falls and protects feet from the blade |
| Safety glasses | Protects eyes from flying debris |
| Sunscreen | Protects skin during outdoor chores |
| Vibration-dampening gloves | Protects hands and improves grip |
| Earmuffs or earplugs | Protects hearing from loud engine noise |

2. Read your mower’s manual
Every mower is different. The manual covers your specific fuel needs, weight limits, and safety systems. Never bypass these protections.
“The built-in safety features most often defeated are the operator presence bail on walk-behinds and the reverse interlocks on riders,” Day says. He warns that disabling them to save time clearing debris is exactly when machines get out of control.
Pro tip: Use only the blades specified in your manual. The wrong blade is dangerous and can void your warranty.
3. Maintain your mower
Skipping spring routine mower maintenance doesn’t just shorten your mower’s lifespan — it creates serious, long-term safety hazards.
Thompson says using an unmaintained gas mower for years risks long-term vibration syndrome, an underestimated hazard leading to chronic nerve damage and severe numbness.
Worn parts also can become dangerous projectiles.
Jeff Yochum, maintenance tech at Ring Container Technologies in Valdosta, says, “If you don’t grease the spindles, the bearing could lock up. Even worse, it could come apart, sending parts flying.”
He adds that neglected blades can also crack and send shrapnel flying.
What to do:
- Change your mower’s oil to prevent damaging vibrations.
- Grease spindles and replace worn blades to prevent shattering.
- Remove the spark plug before servicing blades to prevent accidental starts.

4. Inspect the mower
Before every mow, do a quick visual walk-around to check for loose parts, leaking fuel lines, and worn drive belts.
If you need to adjust the deck height or fold the handle, turn the engine off entirely.
“The most common routine hand and foot injuries I see are people adjusting the height lever or folding a handle with the machine still live,” Day says.
Severe cuts and pinches happen in an instant if the machine shifts.
“My neighbor almost lost a toe to a push mower blade,” Yochum says.
What to do:
- Check the fuel lines for cracks or leaks before adding gas.
- Check the drive belts for fraying or wear.
- Turn off the engine completely if the mower starts vibrating heavily or making strange noises.

5. Clear clogs safely
Clearing a clog by hand is a major safety hazard. Day cautions against “reaching under the deck just to pull the wad out,” noting that the blade can still shift even when the engine is off.
“Even with the engine off, the blade can still move from stored momentum, a bumped blade tip, or the driveline/belt tension settling – so your fingers become the ‘brake’ in a hurry,” he says.
Day’s safe clearing method:
- Shut the mower down completely.
- Disconnect the power (pull the spark plug wire, remove the battery, or take out the key).
- Use a stick or scraper to clear the jam from the side of the discharge chute.
6. Check for yard hazards
Walking your yard before mowing prevents serious accidents.
“Walk-behinds hurt people through contact, while riding mowers hurt people through mass and momentum (a heavy forward force),” Day says. Hitting a hidden hole with that power can easily launch you out of the seat.
Slopes require even more caution.
“One of the most common mistakes we see is mowing straight up and down with a walk-behind mower instead of going side to side,” says Taylor Olberding, owner of Heroes Lawn Care in Omaha, NE.
What to do:
- Push mowers on slopes. Always mow side-to-side.
- Riding mowers on slopes. Always drive straight up and down.
- Use caution on 15-percent grades. If you feel unsteady or the mower tilts, it’s too steep.
- Check whether the lawn is wet. It damages the turf and causes dangerous slips.
7. Remove all debris before mowing
Because mower blades spin at 200 mph, hitting a rock instantly launches it fast enough to break a window. Day warns that even “tiny grit and dry clippings come out fast and low.”
What to do:
- Pick up all the yard debris, including rocks and sticks, before starting the engine.
- Never tie up the deflector shield; keep it down to block flying debris.

8. Follow safe start-up rules
Starting the engine safely requires a few strict rules, beginning with who is allowed to operate the machine: According to the American Academy of Pediatrics, children must be at least 12 to use a push mower and 16 to drive a riding mower.
Always prepare and start gas mowers outdoors.
“Starting a gas mower in a closed garage can allow carbon monoxide to build up to dangerous levels within minutes,” Olberding says. He points out that you may not realize the risk of this invisible gas until it’s too late and you feel dizzy.
What to do:
- Only start gas mowers outdoors to avoid carbon monoxide buildup in garages or sheds.
- Fill the gas tank outdoors while the engine is completely cold.
- If you run out of gas mid-mow, wait at least 10 minutes for the engine to cool down before refueling.
- Never operate a mower under the influence of drugs or alcohol.
- Don’t touch the engine cover while the mower is running—it gets extremely hot.
- Turn off the mower completely when it’s unattended or not in use.
9. Never reverse near children
Backing up a riding mower is one of the most dangerous situations when mowing your lawn. The Consumer Product Safety Commission estimates that riding mowers cause about 90 fatalities annually, and 1 in 5 victims is a child, typically struck when a driver backs up without seeing them.
Because a heavy cutting deck can pull a child under in a split second, keeping them far away is your only defense.
“If they are close enough that you have to raise your voice to warn them instantly, they are too close,” Day says.
What to do:
- Mow forward whenever possible. Plan your pattern to minimize reversing.
- Before backing up, stop completely, look behind you, and confirm the area is clear.
- Keep kids and pets inside behind closed doors.
- Never allow a child to ride along on a riding mower, even for a short trip.
FAQs
The best time to mow is mid-morning (8-11 a.m.). The dried dew reduces the risk of slipping, and the cooler temperatures prevent stressing the lawn.
Battery or electric mowers eliminate gas hazards, but Day says a trigger bump can still start the blade. Olberding adds that their quietness creates a false sense of safety. Always remove the battery before maintenance.
To prevent damage and fire risks, empty the gas tank or add fuel stabilizer. Store the mower and extra fuel in a dry place, away from living spaces and heat sources.
