This past winter I saw this new stump grinder tooth and pocket that Vermeer was coming out with "early this spring". I really like the look of them, kind of like Green teeth but with 2 cutting surfaces on each tooth. I was going get them for our 252 but they never were released. I was at Vermeer last week and they told me the teeth will not be out until the end of summer. I was pretty bummed out since I thought these would make life a lot easier in the stumper world. Oh well maybe next season.
