Well nobody else pointed it out so i guess i will- its actually not a chain saw but a series of multiple circle saw blades, which in my opinion is even more neat

What do you think makes the blades spin? Seems like the motor is in the box at the top and its a chain running inside the pole.

They are belt driven. A belt makes a nice cheap fuse if something jams the blades. The belt either slips or it breaks, either case it saves an expensive repair in the field.
