Walk Behind Trimmer can provide you with different walk-behind trimmer accessories. We collected 21 brands and many models with the manufacturer’s specification for you to read-on, compare between them and find out which one is suitable for your needs. Wheeled string trimmers, also called walk behind string trimmers, feature rugged string trimmer heads attached to a walk-behind frame and use two large wheels for maneuvering over rough terrain. A walk-behind string trimmer covers a much wider cutting area than a hand-held string trimmer. Thick fields of weeds and overgrown lots are no match for such a powerful piece of equipment.
