digging in clay

[yankeepac]

Putting up a horse fence, and have a long line where I hit clay at each hole. the bushhog auger seems like it has plenty of power, but the bit only goes in a few inches, and then the hole has to be dug by hand to breakup the clay in the hole. taking about 30 minutes a hole. No rocks have been found. Is there a particular technique that eluding me? Can I put a different tip on the bit, to pull the bit in more aggressively?

I don't know what kind of tip yours has but I got one from TSC and the carbide cutters to go with it. Been very pleased so far.

For me, and I have red Georgia clay and then rocks, I have to put additional downforce on the auger itself. Sometimes I use an iron bar and others I use a 4" post to apply the leverage.........God bless.......Dennis
