Abstract
A debris blower includes an engine mounted to an engine mount and connected to a turbine. The engine mount and housing of the turbine are respectively mounted between a second side of a frame and first and second longitudinal supports connected to and between first and second sides of the frame. A screen guard is secured utilizing bolts extending in a non-rotatable manner from a top plate connected between the second longitudinal support and the second side. Due to the frame and engine mount having a parallelism and flatness tolerance, the engine and turbine can be aligned without shimming. A sensor senses first and second trip devices positioned at circumferential locations on the exit nozzle to rotate the exit nozzle to preset angles. Remote and hard wire controls each include direction and speed switches. A resume switch throttles the engine between idle and operating speeds.
