Questions and answers
I have a Hyundai single stage snow thrower, Model Number HS4620. My chute rotator is very difficult to use whenever I want to change directions of the shute. It's become now impossible to move at all. How do you replace the cable(s) for the chute rotator? where and in what direction should they be fed, etc, etc. Diagrams would be very useful and helpful to follow along with or a video. Thank you.
