I have the same tractor, great little workhorse. Two things that I don't like about it though, is that you can only board the tractor on one side and the backhoe operating seating is very cramped.
I can't say I'm proficient, there is still some jerking action when I'm operating it, but I got comfortable with it after a few hours, it takes repetitions
I hadn't given the ax work much thought but thanks. All the stumps I've removed before the tractor was with a shovel and ax, I guess old habits are hard to break.
