DeWalt 20V MAX Leaf Blower
Lawn · lawn
Cordless leaf blower on the DeWalt 20V MAX battery platform. Quieter and lighter than the backpack — the right choice for post-trim blow-off on small jobs, detail work near building entries, and noise-sensitive properties. Not designed for fall cleanup volume — use the Troy-Bilt backpack blower for large-leaf-volume work.
