No. But I have described a congruent example that does. And my only experience with the vertical hitch is with the Baldwin. Perhaps it is something that only the Baldwin will produce, but it is most definitely there. Have you removed the vertical hitches from the Baldwin to see if it goes away (obviously, this isn't possible without major redesign)? Maybe it is the suspended plate, but I wager that if the vertical hitches were not in place, it would not be there - at least not so prominently. Perhaps the vertical hitches you added had other factors that quelled the vibration. Since you were adding them to a design that previously did not have them, the hitch was closer to the plate than the accujust so the pitch of the vibration was higher and not so offensive? But the grunt of the stob doesn't lie. The vibration is transmitted very long distances through solid earth from a simple 1 1/2" x 1 1/2" wooden stake. And I know that the Baldwin accujust plate rings. It is the exact same model. Jeff
