Back in the mid 90's and early 2000's i was hard pressed to find a sewer project that lacked a Hippo vibratory compactor mounted on the back of a D5C or D37E dozer. Now I can't even find them in a google search. did the company fold, or were they replaced by something more effecient?
a what?..... Pj
PETA got them outlawed; you can't flatten hippos anymore, you have to move them to a new habitat
that is one of the funniest things i have ever seen.
Is "hippo rollers" the same thing as cow tipping only in Africa?
I finally found paper evidence of their existence! from May 1997 issue of Michigan Contractor and Builder: Apparently patented by "JB Development Inc, Holt MI, close to where I grew up which would explain why no one else had heard of them and why I had seen them all over... http://i193.photobucket.com/albums/z269/demoguy324/Misc%20Michigan/sc002405e3.jpg
