Saturday morning I was finally able to coordinate my time with a friend with a tractor and we set to work exercising the stump left from the large pine which was felled. The machine was admittedly small for the task at hand, but I was limited to the size I could get in the back yard. I only have about 7 feet between my house and the neighbours fence.
I did not think a pine tree would have so many tap roots! We found a half dozen roots as large as my forearm running straight down. We had to undermine the stump with a shovel and just keep working at it until it broke loose. 4 hours later and it was finally free!
We then set to work with rough lay out and excavating for the thickened edge slab:
