BUCKIN' AND HIS PRO MAC 700, VOLUNTEER IN THE PARK - YouTube
Bucken has no chain brake, must of been an earlier Mac edition..
I dont get it I cant cut a stick without an eye full of sawdust and Bucken has neither ear or eye protection on from one of loudest saws created but he did wear ear protection for a little bit @14:45 after he flooded out the Mac. What a mess he was in, he had no where's near the right equipment for that job and I dont think I could cut wood with a axe on my belt. I hope someone has logged that mess by now, be a waste to let it go to rot....
