No. If you can get a hole drilled vice dug go for it. I was offered
factory made rebar cages suitable for either, take your pick. I chose
square and backhoe over round and drilling as the lowest bid I got on
drilling a 5 ft diameter hole was $2000. Extra concrete due to backhoe
precision was way under $2000. Back hoe cost $80. The drilling folks
wanted me to be liable for any teeth they might break.

I have an HDX-589. I'm in the planning stages for getting the tower

I ran across a driller yesterday that can drill the 10' deep hole to a
diameter of 7' (87" to be exact).
We have excellent soil here for self supporting towers, caliche.
Digging by hand is out and using a back hoe would probably make an
over size hole.
Is there a reason not to use a cylinder vs a square hole?
