Think those are sold by Northern Tool Company and a couple other catalog dealers. Think another name for them is Jimnie or something like that. I seen a couple in person here in New England. Owners bought because they were half the cost of a Ford/JD/Kubota.
I don't know how good they really are. I have never seen one on a dealers lot as a trade in, so owners are either holding onto them or sending them to scrap?????
