Extreme Dangerous Climbers Dump Truck Bulldozer Operator - Largest Heavy Equipment Machines Monster.  Hmmm let me try and drive a 70 year-old machine through a river that's flowing at 30 or 40 miles an hour and see what happens.  The guy on the dozer trying to cross the river , I`ve been in a similar situation . I had success  by being patient instead of becoming one . Rivers that fast are usually rain fed  & will drop , plus it`s cheaper than a rebuild   Those excavators are fantastic machines. Good idea to have one around whenever an idiot is operating heavy machinery.  They must have  very allowable  weight  limits  in  some  of these  counties, and allot of no knowledge operators.
