Whern we moved in there was an 18" wide pine stump which was 2' tall and we dug it out, just the two of us over a fortnight or so.
Tools needed - axe, branch saw, assorted spades and trowels, sledge hammer, crowbar and lots and lots of swearing...
I'd try one of those products that you drilll holes in the stump and pour it in to both kill and accelerate decay. Or move house!
