Sometimes taking a supposed short cut can prove to be a more expensive and time consuming way to solve a problem. Since I have a Land Pride HD25 PHD (SSQA model) with standard 9" and 12" augers, the temptation is to use what I have and try to make it work. I find myself in that situation, and perhaps foolishly ordered a Land Pride 6" rock auger in the hope that it'll help me achieve the objective of making a bunch of 4ft deep holes in my very rocky ground.
My thought here is that spending around $1,400 on a 317-258A rock auger is worth the risk. If it works then great, if not, hopefully I learn something and I'll still have the auger that I could use elsewhere. Considering that I have very little cost into this shed project, and that it would cost tens of thousands of dollars to pay someone to build it, I think I can absorb the cost of a rock auger regardless of whether it works or not.
The desire is to end up with 14 holes in two parallel, symmetric and straight rows, but it's highly unlikely to happen. The obvious way to do this would be to rent a large excavator and to dig two trenches to a depth of 4ft and position posts accordingly. But then I'm reminded of the fact that my neighbor (a contractor with lots of equipment) decided to move his 40ft x 40ft shop about 8ft to the west to avoid a massive boulder that was in the way. He didn't want to blast it out to make room for the foundation. So even with big equipment, not all problems are easily solved. That's oddly comforting.
I envy those with rock free ground.
