Abstract
The snow thrower includes an impeller housing carrying an impeller for rotation about a transverse axis and having an upwardly open, forwardly inclined discharge chute through which snow is propelled by the impeller. One or more upwardly extending deflector vanes are disposed in the discharge chute for directing the discharge of snow. Each deflector vane includes a pivot pin which extends rotatably through the transverse rear wall of the discharge chute and a control mechanism, located exteriorly of the discharge chute and connected to the outer ends of the pivot pins, is operable to selectively pivot the deflector vanes between forward, left and right discharge positions.
