Had to post, not too often you will see something like this. It happened yesterday. Operator was driving across the top of the hill when the belt that supplies power to the hydro pumps broke. Unit lost drive power and steerablity. Front end swang down and gravity took over. Operator paniced and forgot about the parking brake. Operator suffered not injuries, except to his underwear. He was wearing his seat belt. The retaining wall is about 4' high, much higher and he would have tested the ROPS. Frame seems to be ok. Deck, front castor wheels and forks, rear radiator mounts, 1 oil cooler, and front extension arms toasted. If he had not had his seat belt on, he would have had many abrassions and possible broken bones from eating the pavement.
