I had a friend who was a construction engineer in Viet Nam. Every once in a while a tank would get stuck in mud that formed a vacuum with the flat bottoms. If the tank recovery vehicles could not pull them out the engineers moved in. They took a chunk of C4 and pushed it under the tank. Had the driver rev it up and then set it off. The C4 would pop the tank up and break the mud suction allowing them to drive out. Dont try this with your tractor. :laughing:
Unless you first installed an extra thick skid plate or using someone else's tractor.......
