Hey Chief,
If Mark H didnt have his identity crisis i would have asked him, if I knew who he was now
9" or 12" should be ok if I remember and it was him who made the reference to clearence on some PHD's...
I'm not going to get the down pressure option besides the expense, my soil isnt too hard so a basic PHD will work fine...
I've used a hand held and it did ok...
renting anything around here typically costs too much....especially the implements where its 50% of a new one, so I now buy them new...
Thanks again....
