This commercial-duty edger is comfortable, lightweight and easy-to-use, which allows homeowners and lawn care pros to enhance the look of edging along driveways and sidewalks compared to what a trimmer can do. RedMax's patented Strato-Charged engine technology leads the pack in fuel efficiency. MaxTorque cutting technology prevents stalling, while an open-face aluminum guard resists clogging. Vibration dampening makes work more comfortable.
