Several times my PTO auger became an unplanned screw anchor, it could instantly screw all the way down into wet/damp CA adobe. The grade 5 3/8" bolt shear pin also sheared. With no reverse and no way it was going to pull out, it was a big digging job. Take off the auger, go get and attach the backhoe (55hp JD tractor). We learned to peck drill carefully if into damp adobe. Hydraulic drive augers have reverse and lots of advantages and can probably be feathered to a slow speed with the valve. I don't think a telescoping shaft would be needed as the 3pt hitch can be in float mode.

btw the JD5410 tractor, front loader, backhoe, auger with downforce + 2 screws, box scraper/ripper with hydraulics, HD single point ripper/cable/pipe puller, hitch mounted boom and wand sprayer is for sale near San Jose, CA, can deliver locally, contact me off list Also a ride on Ditch Witch and Komatsu D21P dozer if any interest.

Has anyone used a post hole auger on a tractor to drive screw anchors??
I think they are a bit too fast, but might handle the job if properly managed. I'd rig a telescoping shaft, like on the pto driveshaft, to go between the auger drive coupling and the anchor eye.
