The RYOBI 40V HP Brushless Edger delivers more power than a 21cc gas edger making it a true gas replacement without the maintenance and hassle. 40V HP technology combines a brushless motor, advanced electronics, and high performance lithium technology, to power through the toughest trenching around your driveways, sidewalks, and flower beds. Functioning as a dedicated edger with an 8" blade, this edger easily adjusts from 0.5" to 2.25" using the single point height adjustment. This allows you to achieve your ideal depth. The 5" rear wheel along with the blade indicator allow for consistent and accurate edging. Achieve maximum control with the variable speed trigger and 2 speed switch. When it is time to change the blade, the spindle lock helps in making the task quick and easy. Best of all, it is part of the RYOBI 40V system where any 40V battery works with any 40V product. The RYOBI 40V HP Brushless Edger is backed by the RYOBI 5-Year Manufacturer's Tool Warranty and includes RY40708 40V HP Brushless Edger, Blade Wrench, and Operator's Manual. Battery and charger sold separately.
