This video was taken way back in 2008 and features a totally submerged Komatsu PC400-7, which is being rescued from a muddy, water filled hole, during a freezing cold Russian winter. The rescue team have deployed 2 Caterpillar D9R’s to basically tug the machine out of the hole. The dozers doing the pulling were assisted by a couple of excavators. 

Heartbreaking to see machines in this kind of state, and I wonder if it was ever rebuilt and put back into service?
