ABSTRACT:
A nozzle for use with a walk-behind blower includes a nozzle restriction due to a sloped upper wall of the nozzle body. The nozzle restriction increases the air velocity in the upper region of the nozzle and forces leaves and debris downward so that airflow through the lower region of the nozzle more effectively laterally displaces them. The configuration of the nozzle body may be adapted to accommodate a variety of engine outputs while utilizing a common design for a blower frame, impeller and shroud.
