I can't stress how much I agree with that statement. I own a B2150 with BH and subframe mount. You wouldn't believe how much damage I've repaired due to the BH on the subframe. And quite frankly the B2150 tail/axle casting aren't at all what I would call beefy to start with. Plus the 3 point limit (enforced by hydraulics) is around 1000 lbs, which tells you something very important right there. As questionable as a 3 point BH may be on various models, I think putting one on a B2150 is about the most likely to end in disaster. If I did, I would put the smallest one I could find on it. If it's marketed for a B7100 or less, or a BX, then you might get away with using it on a B2150...
