Yep, and root balls hold a lot of dirt, which ups the weight a lot.

That's one major advantage of using explosives to pop stumps out of the ground, rather than heavy machinery - the blast shakes nearly all of the dirt off. Much cheaper, too, if ANFO [Ammonium Nitrate/Fuel Oil mix] is used as the main charge.

And of course, blowing stuff up is just good fun anyway!

BTW, there's nothing illegal about this - have had to let it lapse now, but I held a Vic Blasting Explosives Licence for 25 years; with the 'mix ANFO authority' endorsement, for up to 50kg on any one day.
