[TowerTalk] Driving Screw Anchors

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.
