    摘要: A blower is provided having a plurality of tubular nozzles removably attachable to the blower enabling an operator to easily vary the velocity and air discharge pattern. The blower forms part of an operator carried power tool having a drive motor spaced from the blower assembly by a tubular boom containing a drive shaft. The blower comprises a blower housing having an axial air inlet and an air outlet defined by a tubular section. An impeller is pivotally mounted within the blower housing and driven by the drive shaft. As the impeller is rotated, air is drawn through the air inlet and discharged through one of a plurality of tubular nozzles mounted on the blower housing tubular section. Tubular nozzles have varying geometries to conveniently vary the discharge air pattern.

    摘要: A battery powered line trimmer having a forward and rearward handle attached thereto, and further having an arm cradle atop the battery casing allowing the operator to rest his forearm upon it during operation. The arm cradle allowing the operator to maintain control of and maneuver the line trimmer by using the rear handle and arm cradle should the need arise for him to release his grip of the forward handle while cutting vegetation. The line trimmer further has a relatively high ratio of mass movement of inertia about a vertical axis extending through the center of gravity to mass of the line trimmer.
