Abstract
An improved blower for moving debris on a surface is provided. The blower includes a frame mounted on wheels and a motor mounted to the frame. A blower housing with an inlet opening and a discharge chute is also mounted to the frame. A fan is located in the blower housing and is drivingly connected to the motor to generate an air flow having a predetermined volumetric flow. An adjustable height, pivotable deflector is mounted in the discharge chute to split the air flow into upper and lower portions. The deflector is pivotable from a first, downwardly inclined position, to concentrate the lower portion of the air flow along the surface to create a lifting force for lifting and moving the debris while the upper portion of the air flow moves the debris outwardly, to a second position, in which the pivotable deflector is upwardly inclined to create an expanded air flow profile. The deflector height is adjustable to adjust the volumetric flow of the upper and lower portions.
