Don't know if ya'll are into this, but saw a Clark 475b loader in an auction so I was reading about them. Found this, thought it was cool. https://www.youtube.com/watch?v=0-rVHgOorKM
I've seen the video before, but I'd forgotten about it. That is a fantastic movie. Two 16V GMC engines side-by-side... running wide open climbing out of the pit. Thank for the link! ps, the bucket curl is z-bar style linkage. I wonder if that was the first on a loader?
