Congratulations.
I also noticed that the bed that you were "deep tilling" was only about 3

below there with the normal tiller blades not an option? This may be Faster, but I bet shovel-out-and-till would have mixed
organic matter into the subsoil better.

I have several patches, shoveling will be a lot of back breaking work.
You will notice that the auger mixes the soil like a mixer, much better than doing it by hand.
