ABSTRACT:
A backpack blower has a lightweight engine, a starter, a fuel tank, a fan, a frame for the engine, two hollow tubes, and a control mechanism upon one tube. The blower improvement comes from a housing and two elbows. The round housing contains the fan and has two tangential outlets. The two elbows have a generally round cross section and a generally right angle shape. On each elbow, the first end connects with an outlet and the second end joins a tube. The elbows rotate and bend, directing leaves and debris with airflow from the tubes.
