We have used them for 15 years (Krinner) For small jobs we used a
adapter for screwing in by hand. An auger made the pilot hole. For
larger projects, used an adapter to a Bobcat or similar. A pilot hole
helped. For that technique, you really have to work to keep the drive
vertical. It tends to angle due to the way the machine's attachment are
works. Chris

Hi Wrenches,
For a long time, we have installed ground-mounted arrays using 1'
diameter holes, 4' deep, filled with concrete and 2" schedule 40 pipe.
Increasingly, I am seeing ground screws as an alternative that could
save time, disturb less ground, and reduce costs.
Has anyone made the switch to ground screws? I feel that similar
equipment would be needed for driving the screws as is used to auger
the concrete based holes. How has this worked for you in reality?
Best regards,
Jason Lord
