Most homeowners use lawn mowers and string trimmers to maintain their landscapes.
Some are gasoline powered, but others are electrical. Electrical tools used outdoors can be extremely dangerous if not handled with care and under the right operating conditions. If the area where you are working outside is still wet from a prior rain, wear rubber-soled boots to provide some protection against shock or slipping. In general, when using a mower or a string trimmer, wear long trousers to protect your legs from stones or sticks and wear shoes or boots with protected toe caps, such as steel-toe boots. Always wear approved, comfortable safety goggles to protect your eyes from flying debris.
