What would you have ground it with, even the larger grinder I rent wouldn't have reached near the top of the flush cut and the roots on the one side were under the stump
. It's out now and all filled in, drive repaired and the dam grade set so water will stay in the retainment (the elm was previously there to stop water) area I built so water doesn't rush across the drive. Still need to do the finish grade and add some more topsoil, that has to wait until I get rhe stump out of there. I made a cut from the center of the stump down the side into the roots all the way across it, then placed a steel wedge in the top and hammered it all the way in. The side it was on opened up about an inch, the other did nothing, now the wedge is firmly stuck in there. I'll probably just lift up one side and put a crap load of firewood under it, then raise the opposite side and do the sam. If I do that a few times it should break in half and lighten up enough for me to move it.
We got hit in 2019 too, lost about the same amount of trees in the front half of our property (around 20
). In that storm we were the last area that had any damage
. We are about 2/3s up the river valley and the wind comes across the valley and slams into our side.
