Great find Martin! I don't have a IH cart....... (Yet) but I would like to have tall sides. I have a homemade vac on a homemade cart that I really like in the fall.
I think both of those may in fact be a "factory" (not IH) set up for a vac system. I'm sure the EZ-vac one is, but IIRC, I've seen that galvanized set-up before too. Something about it looks very familiar....
