I see you have the mmm on with the hoe in place too, I would caution you to take the time to remove the mmm when working in rough locations as you can easily damage it.
Any trouble with the stumps? I received the same setup as you (less the MMM)yesterday. I dug a 50 trench for wiring and have about six small oak stumps to remove. Learning, but not there yet on the BH.
