Like skidsteer says, with the New Holland you have to have a very good eye or preferably a helper guide you when drilling holes. You will have go forward and backward nearly a foot after it's done to keep it straight. Eventually once you get a bunch of straight holes, it gets easier and better. The deepest hole I dug was 24" diameter, and 13' deep using extensions. It wasn't pretty and it kind of looked like a lazy snake going down

And as I found it's anything but vertical lift---I have picked up slabs of concrete with no problem UNTIL I just barely reached the top of the 10' tall dump truck and ended up resting on the buck board--the last foot or so of lift it starts going forward which is not a good thing when you're lifting on the margin anyway.
