Wow, what a project to get the grader free! It took over an hour, and the problem was the grader’s weight. They decided to try to pull the grader out from the roadway side, and filled in the trench all ’round so that if it moved, it would go only more level ground. At first they tried to use the crawler’s bucket to pull at the rear end of the grader, but the leverage problems quickly made it apparent that power was lacking. Once they added a second grader with more cables, the back end came out of the hole and she was up and drivable. The tracks on the crawler didn’t do the pavement any good, but damage was minimal.
The video below is about 6 minutes long, if you have that much time to waste. Enjoy!
