do you run your wackers and trimmers full throttle? i have very little mechanical ability, but someone told me a long time ago, that running them full throttle "beats on the machine." it made sense, i only run them as hard as i have to. my wacker guy though, he runs it balls to the wall all the time. a few weeks back he took out a window. listen to this...thursday while we were mowing, i look across the yard, and he's just standing there, wacker laying on the ground. i though he was too hot, taking a break. after he didn't move for a few minutes, i went over. it seems, he was wacking, full throttle, and kicked up a rock. the rock, went into his nostral. the rock, was bigger than his nostral, but had so much intensity, that it split his nostral open, and went inside. he was stunned for a few minutes, had a bloody nose, was able to get the rock out, and had a small tear on his nostral, no stitches required. wack full throttle, or not?
