ABSTRACT:
An electrically powered snow blower discharge chute adjustment mechanism generally comprised of a meshingly engaging gearing arrangement wherein one of the gears is operably connected to a conventional electric motor (the drive gear), and the other gear is fixedly, circumferentially attached to the discharge chute. A three position toggle switch positioned at the operator's station of the snow blower is electrically connected to the motor for permitting the operator selective control of the direction of rotation of the discharge chute through power generated by the motor. Further, two notches are removed from opposite ends of the gear attached to the chute. The notches provide space in which the drive gear may rotatably idle when it is not meshingly engaged with the other gear. In addition, a spring loaded plunger is respectively positioned adjacent each cutout. The plungers operably engage a biasing bracket to automatically, effectively urge the two gears back into engaging relation if and when the two gears become disengaged.
