Hello; Important ag tip; if the wheels of the tractor are digging deeper furrows than the plow shares are then it’s to wet to be in the field to begin with. When pulling hard with a chain should always put a tire in the middle. There's a vid on here of a guy pulling out a jeep and goes through window and caves in his face. At 1:47 the guy blowing the tractor on fire. I guess that Superman can put out a fire by blowing but not him! What farmer would go to a muddy field to make ruts any farmer would wait till ground drys. One never ever gets stuck in the mud with a tractor. I haven't, not in the last 20 years since I am farming. It is all down to the utter stupidity that is overwhelming in the farm and construction industry. For any and all of these situations to happen you first have to make a monumental mistake and misjudgement.
