I was poking around on YouTube the other day and I realized there are whole bunch of people building all kinds of weird vehicles, mostly with wheels, but some not. Today I was looking for multi-wheel vehicles and I came across this site, which has more weird vehicles than you can shake a stick at. Many of them are failed prototypes, but many were also successful in their highly specific roles. Most are big machines for industrial or miltary applications. This one is a prototype built by John Deere. Reminds me of the Imperial walkers from Star Wars.
