Spring is here, so it's time to think about beautiful green lawns. And lawnmowers -- which can be fast and dangerous. Before mowing, check every inch of turf for rocks, wire and debris. If hit by a mower blade they could be launched with deadly force and shoot out faster than a speeding bullet. Keep bystanders to a minimum. Kids, friends and spectators could get hurt. Be especially careful when starting a mower. Wear sturdy shoes and keep hands and feet away from the blade at all times. Always turn off the engine when you step away, even if it's only for a moment. Never fill the gas tank when it's running or hot. When cutting wet grass or mowing slopes, make sure you have good footing. In case you do fall or slip, know how to shut down the engine fast. With a little care and extra effort you'll have a beautiful lawn all summer long and be around to enjoy it. And that's the On The House tip for today.
