Mate, I have broken my share of Brushcutters..the NEW stihl..”Stihl aint working”.. is the saying we ran with. yes, 25 yr ago they were made with real metal, real engineering. Today, its SHINDIAWA or go home and cry. We have bounced those things across roads that would shake the rear end out of your XR. they have rattled and bounced in trailers with 20ltr drums of water/poison/fuel, boxes with axes etc etc. you cannot kill them. Like i mentioned, they even run when the slide hangs out the carby. they scream like a banshee on heat, cut a track to route Satan outa hell they would. The kick they deliver when they flick back out of a tree trunk is UNBELIEVABLE. Toward the end of my time doing this we modified a Canoe rack to tie the machines down on..to save on the bits that were getting destroyed..like the carby slide screw piece.
