Anyone have any experience with the weight kit sold for the Bush Hog or Rhino Post Hole Diggers (PHD). I haven't been able to find one yet at my local dealers. The online instructions show a hole drilled through the boom, but my boom doesn稚 have the pre-drilled hole in it and I am not real keen on drilling one either. Are there other options for adding weights to the boom? I am not ready to jump up to hydraulic down force right yet.
