Enter the RYOBI 40V System with the 40V 15” String Trimmer Kit. 40V technology delivers more power than a 21cc gas string trimmer, making this trimmer a true gas replacement. Experience gas performance with just the pull of a trigger, no maintenance or hassle. Achieve up to 71 minutes of runtime so you can tackle your yardwork without any interruptions. Easily transform your string trimmer into a variety of tools with the attachment capability to tackle any job around the yard.
