Yes, but I cant for the life of me remember what we called them :Banghead
Didn't the Banana Splits run a couple of them
Agri-Cat :yup new it would come to me if I didn't push it. Thinking about it the Banana Splits were 8 wheels ( I think )
The Banana Splits were playing with Amphicat, 6 wheeled, amphibious ATVs. I had one back in the early 70s, fantastic rig for a duck hunter in beaver pond country. Weak point was the tires, they were just thick inner tubes, no cord in them and they were vulcanized to an integral wheel. Instead of airing them up to a pressure you wrapped a tape around them and inflated to a diameter, 63" IIRC. Came out to something like 3 PSI.
