“…It's like I built a miniature version of the machine in the movie fern gully that clears the rain forest.”

And OMG… that’s exactly what I’m picturing as I visualize this beast and your experience of using it based on you’re description. 😂

You have much better means than I do.
Ive primarily painstakingly used pure blood sweat and tear operated limb snippers/ hand saw,
eventually I upgraded to a sawzaw and chainsaw;

if it’s a big leftover stump, start a burn pile from said endless, fruitfully growing stupid pokey, prickly brush so as a cool 😎 byproduct you create…. flexible options to where you’d like to have a bonfire.(!)
Yeah it probably won’t be completely gone cos the stuff burns up quicker than the stump does, and it’s not really pretty, but it’s nicer than being swallowed by briars, and good things there’s never ending supply of brush so some day the stump might actually be completely burnt gone 🥲
