We are located on what is known as a drumlin. 24" of soil more or less, hard-pan and then gravel. There are stones through the profile from softball size to ones that will fill the bed of a pickup truck. I often need an excavator for some of the stones when we are getting ready to plant. I like the ripper idea although the less I disturb the soil the fewer stones I have to contend with. The large Best Angle stakes have worked well so far and drive in well due to their small size but I am getting nervous about their longevity. The longest they have been in the ground is nine years.
