My neighbor did some research on the subject and discovered that some  
designs are to prevent rolling past the 90 degree point.  The ROPS on my JD  450 
dozer is very tall and I believe would prevent going all the way over.   Of 
course if you were driving sideways on a steep grade I think the machine  
would go all the way over, probably several times.  I believe that there is  
some design requirement the ROPS be able to withstand more than one complete 
 rollover.  Like Dave said ROPS don't prevent rollover. :)   I think there 
are too many variables to make you safe during a  rollover.  How many people 
wear the seat belt-- I don't, and without a seat  belt chances are good you 
will end up under the machine.   :(
