You are correct. Every once in a while we get nice dark loamy dirt, but it is about 4 to 1 on each hole we dig.
The trick is:
- auger at idle
- auger a foot down and stop auger
- remove rock and debris around auger
- start again go as far as you can down.
- pull auger up a bit remove debris
- Rinse and repeat.
Holes were taking 30 minutes to complete are now taking 10 minutes
