The Quick Change head allows you to convert from bump head to Aero-Flex®® blades in 30 seconds or less! The Bonus Aero-Flex® cutting head utilizes nylon blades to better cut through heavy vegetation without breaking or snagging on brush and obstacles. The TB685 EC trimmer comes equipped with a .095" cutting line that creates a 18" cutting swath and an adjustable Pro handle for both right and left-handed use. The TrimmerPlus® attachment system provides the ability to tackle multiple tasks with one trimmer. TrimmerPlus® attachments and JumpStart™ sold separately.
