Having a small kubota 12hp excavator myself, I am happy to see swales made with this type of excavator. One question though, How to you keep your trench level while digging?? or do you have a laserguide?
I did 3 scoops with an excavator while building a hugel. The first one had a stump in it which I thought was neat.
“There are no words to express the abyss between isolation and having one ally. It may be conceded to the mathematician that four is twice two. But two is not twice one; two is two thousand times one.”
