Is It Safe to Mow a Steep Slope?

Mowing slopes greater than 15 degrees poses a severe risk of lawn mower tipping, rolling over, or sliding, which can cause catastrophic physical injuries. Understanding the physics of your specific machine is crucial for backyard safety.

The Golden Rule: Up-and-Down vs. Side-to-Side

• For Push (Walk-Behind) Mowers: Always mow across the slope (side-to-side). If you slip, you will fall to the side, rather than pulling the dangerous spinning blades down directly onto your feet or body.

• For Ride-on (Tractor) Mowers: Always mow up and down the slope. Turning a heavy tractor sideways on a steep hill drastically shifts the center of gravity, causing the machine to roll over sideways onto the operator.

Pro Tips for Mowing Slopes Safely

• Never Mow Wet Slopes: Wet grass completely eliminates tire traction, making braking impossible.

• Set the Throttle Low: Maintain a slow, steady speed. Sudden acceleration or sharp turns on a hill can instantly lift the front wheels.

• Clear Debris First: Rake away rocks, hidden tree roots, and toys before starting; hitting an object on a hill can flip a mower instantly.
