rico,
Been following this thread (as I use a front end blower on my 600' of crushed slate drive...ah, with a lot of stones that some how got there while I was doing other things with the tractor /forums/images/graemlins/tongue.gif). The one thing I have not seen mentioned is that, yes, most small stones will just go right through and hopefully not break a car or neighbor's window, etc.. However, if you have trees, or other hard surfaces within reach of the flying stones, be careful where that chute is aimed when you go by them. I've had a few stones bounce right back at the tractor, and/or my head /forums/images/graemlins/blush.gif.
Just a note from the "Safety Police" /forums/images/graemlins/grin.gif
