well here i am. worked 10 hours today clearing a nearly half mile long fencerow. that 066 gets heavy towards evening. got a couple nice big fat red oaks, though. for some crazy reason when i got home i just had to fire up my big muckaluck, just to hear it roar. how far can your biggest saw throw chips? i found chips off this at 19 feet out. try and beat it. no cutting downwind...............
