As part of the ONE system, one battery fits over 100 tools across DIY, Garden, Automotive and Crafting, the Ryobi RY18EGA-0 Edger is ideal for keeping borders crisp and tidy. It is also great for preventing invasive weeds growing into the flower bed and plant roots from growing into the lawn. The Edger is designed with a 4-step height adjustment to fit all needs and a dual serrated 22cm blade for longer life. The front and rear wheel allow for added stability and easy alignment. The RY18EGA-0 is sold as a 'bare' tool (without a battery or charger) but is compatible with all batteries and chargers across the 18V ONE system.
