Shown is my stump pulling system. It is a 42:1 compound block and tackle sized to deliver 20T to the stump using a modest size pulling vehicle. I”ve done about a dozen stumps with this rig and, in all prior cases, the stump tips over slowly, inch by inch, and grudgingly crawls out of its crater carrying a dirtball about the size of Montana. This time the combination of tree rot and ground condition produced a dramatic fracture. The stump flew fifteen feet in less than an eye blink. That weight at that speed would certainly deliver lethal force to anyone standing downrange.
