Tim, I'm not sure if this is what you mean't but the chains lift the plow and are used as a safety device. If your plow breaks down and you need to get home you can jack up the plow and shorten the chain .
You would'nt beleive how easy this thing is. They say you can get it on your truck in about 35 seconds. I'm a newbie and my fastest time is 26 seconds. My kid can put this thing on my truck if I would let her near it while I'm operating, but I don't.You guys are right about it tripping funny,though.I've had that thing standing on it's point, just like it's namesake, a big V!Boss has to be one of the toughest plows made. Good for a rookie like me to start out on.
