We do a bit of sidewalk r/r in Champaign/Urbana Il. They require roots be sawed on each side of the new walk . Supposedly , the key word , they won't come back . We rented a Vermeer walk behind . Run it down each side of existing walk , remove walk and roots as you grade for new walk . This unit runs on the walk with cutter wheel offset to the right . They may make one for a skidsteer . RD would know more about this .
I thought about that, but since Jim is on the other end of the world and mentioned that the trees may die, I didn't want to go there. I've never heard of the trees he has next to the drive and don't know what kind of abuse they'll take. About 20-years or so ago, a certain concrete company was talked about on the Rick Dees radio show for WAY too long (for my liking anyway.) Seems the contractor had killed his very expensive imported tree. I seem to remember cutting those roots myself with a sawzall when we set concrete forms. OOPS!
For an interesting read on oak tree wilt root control, check out Yellowdog's thread on the heavy equipment forum on lawnsite. He had a long-arm trencher specially built to use (mainly) on his property.
