I use my rototiller all the time on my gravel driveway. It surely does loosen up all the stone, kills the weeds and renews the material. It works even in the dead of Summer when the material is packed like concrete. Then I use a landscape rake to crown and level it. Its no problem for the tiller (a 5' Yanmar). I put the gate in the full up position and run the tracktor backwards in lowest gear. This make the tiller dig into the material better without bouncing very much. It can make some noise, though. Whoever says it won't work or can't be done needs to develop an imagination, some creative thinking, and stay off the dumb pills. Now if you bought one of those little tinney tillers for grooming your cat's sandbox and leveling the sawdust in your Mommy's tomatoe garden, I could see you having a problem. But this is a solution to a situation that you don't need your checkbook for. Piece of cake.
