another tip for ya is to build a snow guard onto the hitch, If you are using a heavy steel tube hitch with a spring on the sled end I have taken a piece of lexan and cut it to fit over the U shaped opening of the hitch and screwed it to the hitch just make sure you do this while it is hooked to the sled you cant go the whole length of the hitch because you wont be able to slide the hitch onto the sled and dont pinch the width of the U shape I will take a pic today and post for ya
