Your telling me. This fall I was taking our combine down the road, couldn't tell what was going on because I was all over the road, had to slow way down. I got to the field and dad came running up and told me to kill the engine. One rear wheel only had two lug nuts holding it on. It was scary considering the road I was going down with it, steep ditches on each side, if it would have fallen off I don't know what I would have down. I guess yank back on the lever and pray. We had just checked the lugs before we started the season too, tight as could be. I took a socket to all the lug nuts on that machine every four days after that.
