Actually it is that deep sometimes, anna_fox7. Nostalgia is a real feeling, not just liking old stuff. It's about missing a time you can't get back.

How much did that mistake end up costing you?

Yeah, the grinder is a nightmare in wet clay. It just turns into a muddy paste and jams up. Ross.felix is right to ask about a puller, but those need dry, solid ground to anchor. In that soup, you did it the hard way but the right way. Hand digging and cutting the main roots is the only real fix when it's that wet. A big pry bar can help pop the stump loose after the roots are cut. Brutal work, but it's done.
