crazy, but it seems to work. I would not want to be the operator if it hits a rock.

There's so many ways that could go wrong.

Let me count the ways...

I don't know why a drilled square hole would be useful.

To hide a stolen washing machine

Perhaps for something like this?

There is actually a special bit that bores a small hole, then expands at the bottom to make footers like that. I am not finding the link right now.

Check out the vibration transmitted to that tractor. I'd be concerned that the bolts holding that tractor together would come loose.

The tractor operator's name is "Dusty".

Often required when a post is supporting a cantilever load. (e.g., a free swinging gate). A round post will eventually sag as the soil is displaced away by the force acting on it. A square hole (actually, the flat side) has a lot more surface area reacting the lateral force. "Square" is frequently specified by soil engineers but often ignored by contractors simply because they only have a round drill or auger. Nobody wants to spend for hand digging.

Engineering was VERY lacking on this design as the “digger” should have thrown the dirt away from the operator! As for usefulness......graves!

I was thinking along similar lines when it first started to dig, but the deeper it got the more the dirt went behind the machine, away from the operator.

and after all that, the bloody hole is round at the bottom.

How does engineer "A" get all that mechanism designed; bypassing a helical tooth arrangement or rotating the other, more logical direction, letting the chassis aid stability?

I wonder what the life of the chains is, it looks like good grinding paste
