US Patent 9290897 Snow thrower chute rotation mechanism

A chute rotation mechanism for a snow thrower having a frame and a chute rotatably mounted to the frame includes a ring gear configured to be mounted to the chute, a drive gear engaging the ring gear, and a handle assembly configured to pivot relative to the frame. The chute rotation mechanism also includes a first cable extending between the drive gear and the handle assembly. The handle assembly is pivotable in a first direction to tension the first cable and rotate the drive gear, thereby rotating the ring gear in a corresponding first direction. The chute rotation mechanism further includes a second cable extending between the drive gear and the handle assembly. The handle assembly is pivotable in a second direction to tension the second cable and rotate the drive gear, thereby rotating the ring gear in a corresponding second direction.
