World Amazing Tree Cutting and Trimming Machine - Heavy Equipment Cutting Big Tree Machine

 That helicopter and those blades look perilously close to them power lines.  2:00 - 3:05  Oh man, I don't think I can cut a carrot with that level of skill.  Wonder what the 5 gallon gas jug was for at the start of the helicopter segment The blades.  After watching this video I understood that some people have so much time and money that they invent complicated machines (and motorised machines) to do simple (manual ) work that is already being done by simple machines.
E.g. Using helicopter for trimming trees that was way too dangerous, complicated and expensive. And the worst part, the trimming was not even done with proper finishing.
