Today Jeff & I got the 6 holes dug for the support columns that will reinforce the corners of the retaining walls. They are all 6 feet deep and we placed SonoTubes in them which will then be filled with concrete and rebar, then tied into the footings.
The extension we had welded on the the post hole digger worked great but we had to make a bracket to attach the hydraulic motor to the end of Dozy’s back hoe.
This allowed us to raise the digger enough for the added length. Our clay soil was pretty tough on the digger and by the sixth hole, it started to wobble a bit.
