Our patented Strato-Charged engine technology, the main engine and drive shaft assembly combines with five individual tool attachments.  (not shown is the trimmer).  These attachments can be switched out quickly and easily, making the Maxtreme “several tools in one” without sacrificing quality or durability.  By using a single engine power source, users maintain just one engine instead of several.  The Maxtreme has seven-point, splined, solid-steel drive shaft.  Reduces vibration throughout the shaft during acceleration and deceleration, an invaluable feature in the field.
