It’s a crazy idea but if this ever happens again, maybe try unhooking the brush hog from the back of the tractor if possible and move only the tractor out. Once the tractor is out, pull the brush hog out backwards with the tractor. I obviously don’t know anything about tractors so maybe this crazy idea wouldn’t work. I just felt so bad for you in this frustrating predicament! Glad you got it resolved! God bless❤️
