FrANKLYN, I have a 4 acre planting that has a layer locally called a "Hardpack"that occurs about 12 to 18 inches down. I used a skid steer with a hydraulic Ram for pounding/driving posts. I drove 5-6" treated southern pine posts 4 feet down with little trouble. Beside the End posts/anchors there is another post every 30 ft or so. In between the posts I planted 10 to 11 Tall spindle trees all secured to 4 layers of High tensile wire spaced every 2 ft. This anchoring has been in the ground for 4 years now and is quite stable.
