Claim:
A snow blower discharge chute having a control mechanism for rotating the discharge chute, the control mechanism comprising: a first driven rubber disc; second and third rubber discs mounted to a swiveling bracket, wherein the second rubber disc is mounted above a pivot point of the swiveling bracket and the third rubber disc is mounted below the pivot point of the swiveling bracket, wherein the third rubber disc drivingly contacts the second rubber disc; a first sprocket attached to the second rubber disc by a shaft, wherein the first sprocket rotates with the second rubber disc; a second sprocket attached to the first sprocket by a chain; a clutch mechanism attached to the second sprocket by and attached to a worm gear, where the clutch mechanism rotates the worm gear, the worm gear attached to the discharge chute, wherein as the worm gear rotates the discharge chute rotates; a first cable attached to a first control lever of the snow blower and a first side of the swiveling bracket by a first cable adjuster; a second cable attached to a second control lever of the snow blower and a second side of the swiveling bracket by a second cable adjuster; wherein pulling on the first cable causes the swiveling bracket to pivot and the second rubber disc to contact the first rubber disc thereby driving the second rubber disc in a first direction and causing the discharge chute to rotate in a first direction; and wherein pulling on the second cable causes the swiveling bracket to pivot and the third rubber disc to contact the first rubber disc thereby driving the third rubber disc, wherein the third rubber disc drives the second rubber disc in a second direct and causes the discharge chute to rotate in a second direction.
