Sounds like we gots to have it. Larry, any pics? If I assume correctly, these are literally screwing into the ground in place of a concrete footing. such that you can place/attach a structural or pipe column or its part of the screw. I can call some local rental yards and do some internet searching, but is there a brand name to the screw, driver, or a specialized 4WD unit? How many did you drive for 5.6kW? I had contacted the outfit that advertised on TV/web for a while a couple of years ago, but wasn't impressed, however, thought maybe with the right soil it could be exceptional tool for quick guy wire anchoring purposes for wind towers. This sounds like something more substantial. Thanks, Peter D.

The piers were in two parallel rows and all were within 1/2" of our string, though that is in the skill of the operator In very rocky soil it might be more problematic Larry Brown Sun Mountain On Jan 25, 2009, at 8:05 PM, Eric Andrews wrote: Does anyone have any experience using Helical screw pier footing for ground mount racks?
