I'm digging post holes in my yard for a fence and have come upon hard
clay soil with tons of tree roots below. I cant get my shovel more
that 2 inches deep. I have to finish my fence because i have half done
all this work to get 1/2 up already. The one side was very moist and
muddy but the trouble section is hard/clay like cememnt.

What are the tools and options I have to inexpensively get these holes
dug? Is there any reasonably priced machine that I should use? I'd
rather do manually if anyone has any tricks....

Neighbour with posthole digger on their tractor? I suspect any hand held
power tool would be useless as anything powerful enough to turn through hard
clay would rotate you in the opposite direction and anything you could hold
still would get through. Aside from that it's a heavy crow bar and muscle.
