I personally have never seen a post hole digger that worked from the front loader, all of the others Ive seen work off the rear PTO. Maybe Im uninformed, is this one of the patents also? All I know is I installed fencing on 13 acres in Tennessee, and I had to guide the tractor operator back to every hole (within an inch or two). If he could have seen what he was doing, it would have made the project that much easier...
