Wow! What must that be like...digging out a stump without it filling up with water as you're working. :) Water table is high at my place. I have a U17 so digging up stumps is an adventure, and I get tossed about too like you did a couple of times. I use a 12k winch secured to a nearby tree to assist in pulling stumps out of the hole. That KX40 seems to do a good job of it by itself.
Kx71 is a great machine but if your looking for more power I would move up to a kx040-4 or KX91-3 or even a KX121-3. The 121 and the 040-4 are almost the same in power wise just the 121 is little smaller of q machine but we have a 040-4 and it's a beast for a mini
I literally was just thinking, wouldn't it be easier to tip the stump out with the tree still on it? And then here you are, 1st comment! Answers my question.
young man , u are digging closed to the stump / u need find the end of the roots first then dig backward to the stump , u want bounce so must ! then the stump will come out lot easy then for sure !
