By now you probably know what a boom pole is from the other posts but I thought I'd throw this in to you - if you have any intention of buying a post hole digger for your tractor, you will also have a boom pole, that is with most models. I have a Leinbach post hole digger and the gearbox assembly comes off with just 1 pin - instant boom pole! It even has a hook welded to the end already. Don't forget about ballast on the front of your tractor when you start lifting something stuck pretty far out the back on a pole.
