Great video showing how difficult dealing with large stumps cam be. As stated in my other video comment I would still have burned it but made the stump the center of my new wood yard burn pile for scraps from that operation over time. Stumps never burn fast or easy but you can how ever light a fire and leave it to do other things around the farm. I’ve always made a plunge cut vertically in the stump prior to burning as a burnt motor oil deep entry point. Great real world showing that things that sound easy can’t be very difficult.
