Hey John,thanks
I would say you are probably going to get chips,
as you always get some stones. The best thing
I can recommend is having the driveway topped with
what we call here "driveway mix", which is very small
crushed stone (again, i think around here we call it #1)
mixed with stone dust. This mixture packs well, and if
you run these small stones thru they blower they do minimal
damage.
If you have seen what has been thru my blower, you wouldn't
believe it. I believe Shulte or Loftness had videos of blowing
gravel with their blowers on their website, my 47 has been there
done that. (i actually had to have a machine shop replace the
side of the blower housing around the impellar because of the
tears in the steel from my ex using it for 1 winter after I moved out)
anyway, there is also some very thin polyethylene sheets out
there that could be used to line the chute if you were concerned.
hmmmmmm...............
