Now that looks like fun.
Unfortunately, I have to paint in the evenings lately instead of tractoring. I pull in the driveway after work and all those logs and boulders cry out to me. Just gotta grip the steering wheel on my pickup, mutter something about self discipline, go inside and pick up a paint brush.
I have quite a few rocks like yours. My challenge is getting them out of their holes without a BH. Lots of hand digging and leverage with a stout crow bar to get a chain or strap under the rocks prior to lifting with the tractor. All without getting myself hurt. The tractor provides the brawn, I (hopefully) am providing the brains. /forums/images/graemlins/smile.gif
I'm thinking of getting a 3PH subsoiler to help to pry them up. Any thoughts on how well that might work?
