Here are a few photos from when we started the foundation for our first building. We rented a big ol 2 person auger to dig 6 holes for sonotubes. It wasn't too rocky, but was still challenging to get to 48" to be below the frost line. We considered trying to figure out how to mount it to the Kubota so we wouldn't have to muscle it, but it turned out to require more brain power than it was worth to dig just 6 holes. We got it done pretty quickly.
