We used the jackhammer to break up the rock both in the trench, towards the street, and around the base of the stump.
This gets us to a level about 9 to 12 inches below the stump.
We can then continue to dig out the dirt from around the stump.
And slowly work our way around the stump.
Taking out rock and roots as we go.
until we have the stump and its roots pretty well exposed.
This produces both a lot of rock, which we are disposing of, and a lot of dirt. The dirt gets mixed with leaves and grass, and then piled up. Initially we were carting it up and onto the part of the front yard that has already been dug up, in the front.
but that area is pretty well filled up at this point, from the sidewalk to the street to the mailbox all the way back to where we are digging. So we started to fill in a small corner of the trench which was pretty well done.
but now we have pretty well filled that area up too.
