DeWalt's DCMAS5713X1 is a powerful cordless grass trimmer which runs on a 54v Flexvolt battery, but the grass trimmer head can also be swapped out for other attachments in the Flexvolt Split Boom system, which include a brush cutter, hedge trimmer and pole saw. The split shaft design not only allows for different attachments to be mounted onto the tool, but also enables it to be dissasembled and packed down to save space during storage or transportation.
