As part of the Ryobi ONE+™ system of over 150 cordless tools for the home, garden, automotive, crafting and so much more, the Ryobi RY18SFX35A-0 18V ONE+™ Brushless 35cm Scarifier is perfect for maintaining lawn health by removing thatch and moss. The Scarifier gently perforates the soil to breathe life back into your lawn and promote growth by allowing water and nutrients to reach the soil underneath instead of sitting on top of the surface. The scarifier has four working depths so you have complete control over the lawn health. Incorporating advanced Brushless technology means more power, longer runtime, and a longer life through its friction less motor. Intelligent electronics constantly regulate the motor to balance power and battery efficiency. The ONE+™ 35cm Brushless Scarifier requires 2 x 18V ONE+™ batteries and runs from both simultaneously. The folding handles on the unit make for easy storage in small spaces in your garage, shed, or workshop. Using 2 x 5.0Ah batteries (not included), the Ryobi RY18SFX35A-0 can scarify a lawn up to 525m² on a single charge. This is a bare tool - batteries, charger and debris catcher (RAC822) are not included.
