Master Outdoor Upkeep

This cordless outdoor power tool converts into multiple pieces of equipment. With just one base unit and a variety of attachments, it’s perfect for properties with limited storage and smaller lawns. While the string trimmer and hedge trimmer attachments, along with the extension pole, are included with the base unit, there are additional attachments sold separately. Those include a blower and chainsaw, which can also be used with the extension pole for more reach, and a mower deck that works together with the string trimmer.
