How about recovery gone bad? These were taken from a job site I was on years back. The concrete truck was bringing concrete for footings. The truck drove up on to the building pad, but found a soft spot on the way in. The driver shut down the drum because he was afraid it would pull him over. I tried to pull it out with our D7H, but broke the tow hooks off. Thats where we stopped. They called a wrecker service that "knows how to get is out, he does it all the time." We sat back and watched the show. The driver could not get enough stabilizer into the pad to keep from pulling himself around. So, I buried the blade on the 7 and he chained up, the end result is as follows. Btw, the cement mixer only sat for 45 minutes, by the time she hit the ground, no cement came out of the drum. Truck had only been in service for a short time.
