Flying Saw
 

Does anyone have any information about the company that makes/supplies the circular saw set ups used on a long line to trim trees on the edges of powerline easements?

No I'm not a saw spotter, rather someone I know is in the powerline business and has seen one once and wants to import one.

Thanks

The best I can do for you is contact Chris Soloy who is now the manager for Prisim Helicopters Wasilla Alaska. When he ran Soloy Helicopters he operated the saw for the maker. He should be able to point you in the right direction.
Hope this helps.
