The soil is fairly hard clay.
I rented a one man 8" gas-powered auger, and the thing would not go anywhere. It just spun but didn't go down. I tried to apply a little weight to it, and it would bind and stop spinning. I couldn't get anywhere with it. Very frustrating.
I really hate to try to do this by hand.
The holes are close to some obstacles so I don't have much clearance.
Any advice? Maybe I just got a bad auger? Can anyone recommend a decent auger to rent?
I'm in the Oakland,CA area.
