Two notes:
First, the only difficulty I have installing the 46 BH is removing the 3PH 1st, when I've been using 3PH implements. Installing the 46 is a breeze, on anything close to a level area, with a little practice.
Second, WATCH OUT for how FAST that boom moves, especially when fully extended dipper. Get it out away from anything and practice with it slowly. Bruises to siding, trees,... can happen really fast. Bruises to people and pets are much more serious.
Have fun. The 46 is a very capable tool.
