I don't have the equipment for that; you have to dig and cut the roots etc without a dozer. What I will do is cut close to the ground and let nature rot them out.
Drill a few holes/ run the tip of the bar in 4-5" , make an "X" add some corn syrup/ cover will rot quicker
The stumps will be behind the fence line so not in the way; I will cut the rest of the stump for the wood.
Yes, I know, I have had that to happen before, I take the axe and easily knock them off; eventually they will die.
salt will supposedly help stop them from setting shoots. Dunno about rotting. I've never tried it, we have termites that work for free. An axe does work good although red oak and black cherry suckers can be rather persistent. Both are probably good for coppicing for rocket stove firewood. I use black cherry suckers in the garden for short poles as they often quickly grow nice and straight.
I thought I would try a back leaning tree; a small sweetgum not too large in diameter for practice. I wanted to drop it across the garden as cutting in the direction of the lean would most likely result in it getting hung in other trees. I made a good notch but messed up the back cut; I angle the bar and the cut ended up being below the notch. I was worried that I was going to have to leave it as it was and wait for the winds to take it down but I managed to drive the wedge in with a large hammer and drop the tree.
I guess. I was a bit nervous on this one when I messed up. I did wait for the winds to die before attempting the tree.. As soon as I saw the tree start to move I ran as fast as I could to put a safe distance between me and the tree.
I got the sweetgum bucked and then the storms started moving in. I still had the poplar in the garden and now the sweetgum. I rushed to get them up and stacked out of the garden so they would not get mud on them. I just managed to get finished when the rain started. I rush home as large drops of rain fell and made it into the house in the nick of time.
