Do not operate mowing equipment around children. Never leave a running mower unattended. Some of the larger or commercial mowers allow the mowing blade to be disengaged and the engine to remain running. If operating a mower like this, take special care when you remove the bag to empty clippings or perform other activities near the mower while the engine is running. Wait until the grass on an incline is dry, then mow across the slope with a walk-behind mower, or up and down the slope with a riding mower to avoid slipping.
Some slopes are too steep to mow with a walk-behind or riding mower.
Never allow passengers on riding mowers. It is very dangerous to let a small child ride on the mower with an adult. If the self-propelling power of a mower is used to transport a mower over a gravel road or other debris covered surface, disengage the blade or turn the mower off and push it rather than mow over a dangerous surface. Allow fuel-powered mowers to cool before adding fuel or working on the engine. Do not add fuel while the mower is running and do not mow or add fuel while smoking.
