Sure must be nice to have rock free dirt.
Right?!
It only looks that way. We've had a LOT of rain lately. The ground is soaked.
I haven't found many large rocks, but lots of smaller ones (fist size down), and sand/gravel/clay.
The picture where the auger is full of dirt, and the 2 of the tractor; to dig there by hand you need a pickaxe normally. There's probably a foot of loosened soil on top at this point (I loosened and dug/sorted a mess of root thatch by hand, that's what's left of the spoil pile.). It's a mess I've been slowly dealing with for years.
It may even be old driveway underlayment. Directly to the right of the hole I dug is a sheet of old pavement 6 or so inches down. Runs over 100 feet as far as I can tell. It's one of the jobs I got the BX for.
The 3 hole spot I don't know as much about. I tore out a dogwood stump from there yesterday, I figured it would be a good spot to start testing the larger auger.
This winter I ran the 6 inch auger about 10 feet from a spreading Norway Maple, it had no problem burying itself.
I've got other parts of the yard that are rougher, I'll get a chance to test it there eventually.
