That was awesome, I had to watch it again!Why do none of these videos show how to get the chain in there? It must be the hard part.This is great how did you make it and what did you pull it with?Didnt show how chain was fed through. was a rope or cable pushed to other end to drag chain in.Can somebody tell me how they pass chain from on end to other before they attached it to the cleaner bearing in mind culvert was clogged.
