A walk-behind string trimmer, also known as a wheeled string trimmer or wheeled trimmer, is a landscaping tool used to trim grass and weeds. It is powered by a gasoline engine or an electric motor, and it has a rotating nylon line that cuts through vegetation. Walk-behind string trimmers are typically used for larger areas, such as lawns and fields, and they can be more efficient and less fatiguing to use than handheld string trimmers.
Walk-behind string trimmers offer several benefits over handheld string trimmers. First, they are more powerful, so they can cut through thicker vegetation more easily. Second, they are self-propelled, so you don’t have to push them forward manually. Third, they have a wider cutting swath, so you can cover more ground in less time. Finally, they are more comfortable to use, as you don’t have to hold them up with your arms.
