The rotation assembly is comprised of a frame structure having a top surface. A longitudinal slot is formed along the top surface extending therethrough. A first pulley and second pulley are rotatably mounted to the top surface of the frame such that the slot is generally therebetween. A hydraulic cylinder is fixably mounted to the frame and has a pin extending through the cylinder arm of the hydraulic cylinder and the slot. Rotatably mounted on the pin atop the frame surface is a third pulley, such that activation of the cylinder arm causes the third pulley to travel along a path defined by the slot. The frame is fixably mounted to the rear of the snowblower housing. A first and second cable is fixably attached at one end to the side of the snowblower chute. The cables are looped around the pulleys in such a manner that activation of the cylinder causes the relative length of the cables with respect to the pulleys to vary, resulting in the rotation of the snowblower chute.
