down faster than it can dig , stalling the machine . Then ya gotta
uncouple the power head (this is driven via a drive cable and torque arm
to a worm and pinion) from the auger and use a wrench to reverse it out
of the hole . Don't forget to cut that root before you continue ... any
way , the reason for this task is to build a carport structure over our
camper . It'll be 12' wide and 11' tall clear dimensions , and 30 feet
long to accommodate the camper and both Harleys . That's bigger than
needed for the camper both wide and tall , but we're considering moving
up to an RV in the future , it's going to be big enough for anything but
a Class A (I think that's the big'uns) which is way bigger than we're
considering . And my back still hurts , but nowhere near as much as if
I'd dug those holes by hand .

You could have done it the easy way. Just throw a shovel of concrete on
the ground for the footers. That's what they did in a 120 unit condo
development where I once lived. Found it out when the decks started
sinking. The building inspector, I think he was last seen headed
for Montana. The FBI raided the home of the mayor a few years later.
The mayor, who was also the paid fire chief in a nearby town, had $50K
in cash hidden in his attic. He plead guilty to multiple bribery charges.
